Personal experience of metalworking practice

When we are inspired by one thing, we can write down a thousand words in our hearts with a pen. Writing good experiences is very helpful for your future growth. The following is my personal experience of metalworking internship for your reference only. Welcome to reading.

The metalworking practice that I personally experienced for two weeks passed quickly. The two-week metalworking internship is a brand-new experience for our college students, which injects a fresh element into our boring and monotonous military school life, and also allows us to learn a lot of things that we could only hear or see on TV before.

Before the start of the two-week metalworking internship course, I was full of curiosity and awe, because before I really came into contact with this subject, I had heard from my seniors that it was a very challenging and challenging subject, and most of the contents we wanted to learn were never really touched before, and the whole metalworking internship process required our full attention and energy. Only in this way can we ensure that we can complete our metalworking internship task well and will do so.

Two weeks of life is very colorful. Experienced a series of very interesting and meaningful experiments such as lathe work, locksmith, forging and rolling, welding, casting and special processing. Through these experiments, we learned a lot of knowledge and skills that can only be learned in the technical training workshop. Although it is impossible to engage in important processing tasks in any workshop only by relying on this knowledge, we can proudly say that we have learned these things and can operate these instruments. With the acquisition of knowledge and skills, we also get a lot of happiness that is hard to get at ordinary times, including the pleasure of completing tasks and the joy of increasing knowledge. In short, the two-week metalworking practice left a deep impression on our life in HKUST, which enabled us to acquire great knowledge and skills and study happily. Metalworking practice life is very good!

Personal experience of metalworking practice Part II Metalworking Practice is a highly practical technical basic course, and it is an important compulsory course for engineering students in colleges and universities to learn the basic process methods and technologies of mechanical manufacturing and complete the basic engineering training. It not only enables us to acquire the basic knowledge of mechanical manufacturing, understand the general operation of mechanical manufacturing and improve our operating skills and hands-on potential, but also strengthens the exercise of integrating theory with practice, improves the potential of engineering practice and cultivates engineering quality.

Because of the New Year holiday, we only have X days of metalworking practice. During this period, I came into contact with milling, PLC, turning, welding, casting, rapid prototyping, die-cutting, EDM, stamping, locksmith and other posts 15. Every day, everyone has to learn a new skill. During my internship, I completed the process from knowing nothing about all kinds of work to making a finished product. With the patient and meticulous teaching of teachers and our inner cooperation, we did not have an injury accident, basically reached the expected internship requirements, and successfully completed the X-day metalworking internship.

In the practice of locksmith, we know that the main data of locksmith are scraping, drilling, tapping, sawing, filing, assembling and scratching; Understand the structure, classification, selection, filing posture, filing method and quality inspection of archives. To tell the truth, locksmith internship is boring. He may have been doing an action repeatedly all morning, but he still needs strength and accuracy, that is, holding a file back and forth on the workpiece. My hands are sore and my legs are stiff when I rest at noon. I finally got the work out in the afternoon. Although it is not very standard, it is the crystallization of my sweat and the result of my hard work at the end of the day. The next work is casting, which can be said to be a complete recollection of the time when I was a child playing with sand. But at this time, in addition to the impulsive heart, what is needed is more care and patience. After learning the CNC EDM, it also needs programming. But that's automatically programmed by the computer, as long as you input the drawings of the parts to be processed, choose the cutting path and put the raw materials away. Then, we learned arc welding under the guidance of our teacher. After half a day of arc welding practice, although I didn't fully master arc welding, I also learned a lot of basic operations of arc welding. We mainly mastered the friction arc initiation. After that, I learned a lot of funny jobs, such as rapid prototyping, wire cutting and counting cars. In these three jobs, I can finish my own work. I feel very gratified when I look at the works I have designed.

Thoughts on this internship:

Time flies, and two weeks are fleeting. Two weeks' metalworking practice gave me a lot of experience. I mainly start with the following points.

1. Through this internship, we have learned about the production mode and technological process of modern machinery manufacturing industry, and are familiar with the main molding methods and processing methods of engineering materials, the working principles and typical structures of the main equipment used, the use of fixtures and measuring tools and the safe operation technology. Understand the knowledge of mechanical manufacturing process and the application of new technology, new technology and new equipment in mechanical manufacturing.

2. Have preliminary independent operation skills in the main molding and processing methods of engineering materials.

3. In the process of understanding, being familiar with and mastering the necessary engineering basic knowledge and operation skills, we have cultivated, improved and strengthened our engineering practice potential, innovation consciousness and innovation potential.

4. The internship rules made by students in the process of internship, such as strengthening the cleaning of machine tools and observing the safety operation rules of various types of work, have also played a good role in promoting the cultivation of students' comprehensive engineering quality.

5. We have cultivated and exercised our own views on labor, quality and economy, strengthened our awareness of observing labor discipline, safety technical regulations and caring for state property, and improved our overall comprehensive quality.

As college students, after more than ten years of theoretical study, we have been told more than once that there is a gap between theoretical knowledge and practice, but we have never taken this sentence seriously and have no chance to verify the actual gap. Metalworking practice gives us the opportunity to master knowledge in practice. Without the rigorous environment in the classroom, we felt the atmosphere in the workshop. The studious eyes of the students and the careful and patient operation of the instructor constitute the common scenery in the workshop.

In the classroom, we feel the importance of hands-on potential, and we can't finish practical work only by thinking and thinking with our brains. Only by having a scientific knowledge system and mastering practical potential, including mechanical operation and continuous accumulation of experience, can we apply what we have learned to practical work flexibly and effectively. The current education system in China makes the practical potential of college students who enter universities through the college entrance examination weak. Therefore, universities in the transitional stage between school and society undertake the task of cultivating students' practical potential. Metalworking practice is an effective way to cultivate students' practical potential. Based on this, students must pay enough attention to this course and make full use of this month's time to improve their practical potential. There is also a learning classroom. Through our hands-on, we supplement and question the theoretical knowledge we have mastered. This is just the opposite of traditional classroom education. These two learning methods complement each other, which can fill the blank and make up for some blind spots of one of them. Through metalworking practice, I feel that the actual production mode is still relatively backward, and I can't actually operate the advanced equipment introduced in the book. The equipment in practice is often labor-intensive and low in technology, but some basic knowledge can be applied in practice.

This internship, let us understand that we should pay serious attention to details and not be careless. At the same time, it also cultivated our indomitable nature and perseverance that we will never give up until the last second!

Personal experience of metalworking practice After nearly a semester of study and practice, our metalworking practice is finally over. In these ten weeks, we have learned a lot of knowledge that books can't. Look at our own innovative works, perhaps not as full of aesthetic feeling and artistic breath as imagined, but still full of our hard work and joy of struggle. At the moment when the metalworking internship tour is coming to an end, I want to say from the heart that we have had joys and sorrows in this unforgettable ten weeks.

First metalworking practice

As an engineering student of Harbin Institute of Technology, it is necessary to learn such an innovative practical course that integrates hands-on and brain. The school did its best to build a well-equipped metalworking practice base for us, which gave us a good place to play our talents and learn skills.

But to be honest, at first, we were still full of strangeness and unknowns about metalworking practice. After all, this is not exactly the same as sitting in the classroom and listening to the teacher. Metalworking practice has more hands-on practice than ordinary lectures and notes. If we personally operate steel machines, big or small, which can only appear in factories and technical schools, and let them listen to their own words at will and make standardized assessment documents, it is really beyond our usual "unsuspecting" college students. Besides, hammers, saws, planers and lathes used in metalworking practice are dangerous. In the first theoretical class, the teacher repeatedly stressed that the first requirement of metalworking practice is safety. The word security has also become the supreme truth that we have been obsessed with for some time. Safe operation is not only responsible for your own safety, but also for the safety of others, and it is also a necessary guarantee for the smooth production of qualified parts. Therefore, in actual production practice, we are adhering to such a principle. In the actual operation of each type of work, strictly follow the teacher's requirements and operate according to the specifications. For example, when welding, we always remind our companions next to us to code the mask. Before drilling, carefully check whether the drilling rig is installed tightly, wear work clothes and fasten the cuffs in each class, and female students wear hats when they participate in lathe work. Although these seemingly trivial details, but really fundamentally put an end to possible security risks, let us successfully and safely end the metalworking practice course. By extension, this also reminds us that we must pay attention to some details in our lives and not ignore the most basic requirements. Details determine success or failure, and it is also the premise for us to succeed in doing something. It is precisely for this reason that there is no accumulation, and there is no miles. On the other hand, metalworking practice has also taught us such a truth, which will make us go better and further in our later life.

Second, the happy metalworking practice class

Although at the beginning, I was inevitably full of doubts and puzzles about metalworking practice and doubted whether I could learn these practical skills well, when I really started these production studies, I listened to the teacher's inculcation, kindly reminded us of possible problems in operation, worked hard to complete my work and even innovated my own research according to the teacher's instruction and the requirements in the book, and gradually mastered the "key points" of metalworking practice. It is definitely impossible not to comply with the production operation specifications; But you can't be timid and afraid to practice. What we get on paper is superficial. We have all heard the story of Zhao Kuo. Therefore, we must do it ourselves, so that we can turn other people's things into our own skills, truly achieve the purpose of metalworking practice, and become a qualified engineering college student who "got the lathe and got the classroom".

I remember that we were milling workers in the first class. At first, we thought there was no difference between the machine tools in the whole workshop. Later, after the teacher's explanation, I found that all lathes have their own unique features, such as vertical and horizontal. It was also in this workshop that I cut out my first evaluation piece, a small iron block. Looking at this polished iron mill, I still have a feeling of joy.

After that, I also studied similar types of planers and lathes. There is also welding. There was always an unspeakable fear of welding. I feel that this high temperature and high pressure thing is in my hand and my eyes are so close. The operation must be very dangerous. I feel I have no confidence. After seeing the teacher's demonstration, everyone went to the welding table with trepidation, installed covered electrode on the machine with fear, put on masks, and tried to weld the riddled iron plate. Sure enough.

However, at first, everyone stuck the covered electrode firmly on the iron plate, so they all pulled it out in a panic. Later, I slowly groped for the spot welding that the teacher said, and realized the feeling reflected by the distance of 2mm, and gradually mastered the essentials. From the initial zigzag welding to the fish scale pattern mentioned by the teacher at last, I feel that I have gained a lot in just half a day.

The fitter should be the one who impressed the most. Fiddler is a big project, and it should be our most time-consuming project. Everyone's task is simple, that is, to make a day and a half of events into a small hammer. Seemingly simple things actually cost us a lot of effort. Take making a hammer as an example. First, the surface should be polished repeatedly with a file until it meets the standard size. This process alone took nearly an afternoon. Then use a circular file to make an arc that meets the requirements and grind out several chamfers. It takes time and energy to grind a seemingly short distance with your heart. At the end of the day, everyone has a backache and has been shouting tired. However, the final result is very good. After the heat treatment process, a bright little hammer is freshly baked, and the smile on everyone's face is the best portrayal.

Third, the process of innovative works.

After studying all the working procedures, we began to design innovative works. After repeated discussions in our group, everyone's opinions changed again and again. Finally, we decided to create a "street corner" work with the house as the main body, which is intended to reflect a harmonious and beautiful corner. It is our ideal to have a comfortable and stable living environment, especially in the current situation of high housing prices, not everyone can own their favorite house. We also want to embody such a beautiful wish through our own hands, hoping that everyone can have their own comfortable residence, happy life and bright future.

However, in the process of creation, there are still many problems. Some points and the connection between points and surfaces are very difficult. According to our original idea, covered electrode welding is neither beautiful nor realistic, and it is very difficult to operate. Fortunately, the teacher still gave us a lot of help and helped us make suggestions. Spot welding is clean where it can be welded, and the corners that cannot be welded are also overcome by punching and folding. In the last period of time, the weather gradually warmed up, and everyone was still full of energy and a clear division of labor. Some are responsible for computer design, others are responsible for hand-made cutting. Although there is still a lack of artistic beauty, we finished the task on time and basically showed the theme we originally wanted to express.

abstract

The process of metalworking practice is full of hardships and happiness, but it is hard-won. The process of learning and making progress together is always worth remembering. Finally, thank the school for providing us with such a hands-on platform for our all-round development; Thanks to our instructors and all the teachers who helped and taught us, you really let us learn what we should have and expand our ability; At the same time, I would also like to thank my colleagues in the same group and other students who studied together. The days when we struggled together were unforgettable, and I believe these are also our precious spiritual wealth after work. In the future study and life, we should also maintain the spirit of hard work and innovation in metalworking practice, keep learning and making progress, and make due contributions to the country!

Metalworking practice has experienced four metalworking practices personally, and there are joys and sorrows. Now think about this unforgettable time in the past, only those who have experienced it personally can understand it. By studying various types of work, we have learned a lot about the principles and techniques of metalworking operation, and also mastered some operation skills and methods, as well as unfamiliar professional terms that used to sound so familiar but now sound so cordial!

Although most of us will not engage in these jobs in the future, or even have the possibility of contact, the experience and feelings brought by metalworking practice are priceless to each of us in our work, study and life. You may not feel the value of some things now, but eventually you will. Everyone has this process!

I also benefited a lot from my internship classmates. Without selfish help, we sincerely encourage each other to cheer and share the pressure of work and the joy brought by success. Metalworking practice is more like a collective activity, which has narrowed the distance between us, filled the gap that once existed, and the charm of collectivism has been vividly displayed! There are few opportunities for classmates to get along with each other in college. Thanks to the metalworking internship for giving us such an opportunity. Such activities are worth learning by the education department.

The metalworking practice is over after five weeks of personal experience, but mine has benefited for life. Although most of us will not engage in these jobs in the future, or even have the possibility of contact, the experience and feelings brought by metalworking practice are priceless to each of us in our work, study and life. Metalworking practice is not only to strike the iron, but also to make an ordinary iron into another ordinary iron.

With the opportunity of metalworking practice, we can apply what we usually learn from theory to practice, and turn a lifeless iron into a work of art with creative wisdom and pleasant cooperation. There are also practical ability, team spirit of artistic creation, hard-working spirit, etc., which are not simple brute force while the iron is hot. The significance of metalworking practice is that non-mechanical and electrical students learn the basic knowledge of mechanical manufacturing technology through practice, improve their operating skills, and lay a certain foundation for the use and maintenance of mechanical equipment in the future.

Some people think that metalworking practice for non-mechanical and electrical majors in liberal arts is useless at all, which is a complete waste of students' time and school resources. People who hold this objection think that the liberal arts major has nothing to do with metalworking, and metalworking is not helpful for future employment. In fact, these pragmatists only see the superficial phenomenon, knowing one thing and not knowing the other. Things are generally related. We can't look at the problem in isolation, but we should look at it from the perspective of connection and development. Although it can't be applied to actual production as quickly as professional students for the time being, it can produce benefits quickly.

But the influence of metalworking on students is lifelong and profound. For example, as a student majoring in Chinese language and literature, even if he is not engaged in mechanical and electrical career. Living in modern society, we still have to deal with the manufacturing industry and understand it. If you become a reporter after graduation and go to a factory to interview, but you know nothing about factory production, even if you have beautiful writing style, what you write will be empty and boring, without blood and meat. On the contrary, because you have the special and precious practical experience of metalworking practice in the university, writing this press release will definitely make you handy and comfortable.

As a student majoring in Chinese language and literature, Zhou's metalworking practice deeply touched me. Just like cicadas are born after a struggle. We are learning theoretical knowledge every day, and we have little or no chance to practice. The school provided me with this opportunity to get close to the machine and learn about the assembly line production in the factory.

We use machines or hand-made products every day, but we don't know where it came from or how it came from. Much like an ironic story I heard when I was a child, a child who grew up in a city asked the teacher, "Watermelon is so heavy, how can I climb to the tree to pick it?" In this modern society, ignorance of machinery and manufacturing is as ignorant and stupid as the first child in the city.

I. Turner

The first metalworking practice is very new to us, so we don't have to stay in the classroom all day in front of the boring blackboard. Going to the mechanical and electrical building of the school, where you can only watch from a distance, do things that you never thought about, and work with saws, hammers, rulers and the like, is really something you look forward to. We arrived at the electromechanical building of the practice base early and waited. After the teacher came, he explained to us the significance of metalworking practice, curriculum arrangement and safety problems in the practice.

Next, I thought the teacher told us about the lathe, the structure of the lathe and how to use the machine correctly and safely. We are liberal arts students, so our receiving and understanding ability is not as strong as that of science students, so the teacher patiently explained and demonstrated to us. Then we are familiar with the structure and individual parts of the lathe and operate on the basis of familiarity. Considering that we are liberal arts students and most of them are girls, the teacher lowered the difficulty requirements for us and let us operate the lathe in pairs to turn an iron car into a hammer handle.

With the rotation of the machine and the roar of the motor, this training room seems to have become a small factory, while we girls wearing red helmets seem to have become workers on the production line. Although we are clumsy and unskilled, we still scream from time to time and call for the help and guidance of our teachers. Our curiosity, enthusiasm, patience and concentration are all integrated into the control of the machine. Keywords tool setting, lathe excircle, lathe cone, finish turning ...

We tamed this heavy machine slowly. On the lathe, the outline of the handle of the small hammer is gradually obvious. Under our unremitting efforts and the patient guidance of the teacher, we finally introduced a small steel hammer handle with shiny metal. Laughter is mixed with sweat, joy is passed between us, and a sense of accomplishment arises spontaneously. I am really happy to see my work on such a huge machine tool for the first time. I believe I will do better and better in the next internship!

Second, fitter.

On the first day, we tasted the sweetness, and we started the next day's journey-fitter. The fitter mainly operates by hand and uses various tools to complete the processing, assembly and repair of parts. In the production process, some precision devices cannot be produced by machines and must be made by hand. At this time, how high the accuracy of people is determines the accuracy of the equipment. For example, the teacher said that the shell of Rolls Royce, the most expensive car in the world, was knocked out by hand. Ordinary production cars, such as Honda in Guangzhou, are all made by factory machines.

This shows the importance of locksmith in production. Under the touch of the document, all kinds of images came out, including lovers, lovely elephants and the Olympic rings. I have to admire the imagination and creativity of my classmates. Although my hands are dirty and worn out, it is worthwhile to see my work slowly taking shape, no matter how hard and tired it is. Holding our own works, we all laughed happily. In today's fitter's exercise, I made two things out of aluminum bars. One is an umbrella, the other is a key. The umbrella is lovely and the surface is smooth.

Personal experience of metalworking practice Six or two weeks of metalworking practice is a wonderful journey with sweat for me.

Shortly after I started my metalworking practice, I joked with my classmates: "Metalworking practice is to let us experience the trouble and fatigue of manual operation, so as to provide power for us to create more advanced mechanical tools." Although it was fun, it was really what I thought. It is well said in "Encouraging Learning": "There is specialization in the technical field". After all, _ _ aims to train engineering students to be senior engineers, not ordinary workers. Because of this attitude, I didn't pay enough attention to it in the first few days of my internship. This carelessness has brought me many difficulties. For example, when the locksmith was practicing with a small hammer, I almost broke the horn. ...

I gradually realized that if you don't work hard, you can't do anything well. Especially some types of work in metalworking practice need a lot of experience. In such a short time, if you don't study hard, you can only take a cursory look. In the end, you have wasted both your teacher's hard work and your own time and energy ... During the internship, more than one teacher emphasized the importance of combining listening and doing, which I think is the reason.

Let's talk about some new thoughts on "innovation" after metalworking practice.

"Innovation" has always been a new concept, and there are many related discussions. Among them, I have always been puzzled by Hu Shi's exposition. He said: "The so-called innovation is the new tricks played when imitating to the extreme", but these two weeks of metalworking practice made me understand this sentence. In just two weeks, we have been exposed to new machines almost every day and exercised a lot. In this case, some of my innovative ideas are likely to bring mistakes, and some are irreparable. Therefore, familiarity with the object is the premise of innovation. Only on the basis of fully understanding the objects we are facing, can we put forward some constructive suggestions and achieve the purpose of innovation. Of course, the purpose of metalworking practice is not to say that we can spark innovation in generate in just two weeks, but to give us a preliminary understanding of some typical technological processes and methods, so as to lay a foundation for future work and even innovation.

In a word, metalworking practice taught me much more than I expected. It established a state of mind for me and provided some new ideas. Here, I also want to give some ideas to our metalworking practice teaching, saying that safety is the first, but we can still broaden the scope of students operating machines. For example, you can choose some students to try some special welding methods. After all, you will be more impressed if you do it yourself. Finally, thank the teachers for their careful teaching in the past two weeks! Teacher, you have worked hard.

Metalworking Practice Experience Seven Metalworking Practice is a very practical basic course, which is a necessary prerequisite for students majoring in mechanical engineering to learn courses such as engineering materials and mechanical manufacturing foundation, and also an important practical teaching link in the teaching plan of non-mechanical related majors. This is of great significance to cultivate our practical ability. But also made us understand the traditional and modern mechanical manufacturing technologies.

As a student majoring in mechanical and electrical equipment maintenance and management (photovoltaic equipment), it is very important to learn theoretical knowledge well, but the practical ability is also very important. Nowadays, many college students, especially those from cities, have few opportunities to do it themselves and poor practical ability, so it is difficult to adapt to the demand for all-round talents in the future society.

The metalworking practice course has brought us science and engineering students the opportunity to practice, which is very helpful for us to go out of the classroom and experience in the workshops of various workpieces and machines. Thanks to the school for providing us with such an opportunity, and also thanks to the teachers who have worked hard to lead and guide our study.

Once again, we put on military uniforms and became a beautiful scenery on campus. I still remember the first time, we went to the metalworking practice base of the school with curiosity and excitement, imagining the happiness of finishing workpiece processing. However, time flies. In a blink of an eye, just two weeks of metalworking practice has ended. In the blue-collar days, we have hardships and fears, but we have gained more happiness and valuable hands-on experience. The kindness and experience of meeting teachers and classmates in the workshop will be an eternal memory in my life.

During my internship, I participated in welding, CNC wire cutting, lathe work, locksmith and milling work, from which I learned a lot of valuable things, which made me learn things that I couldn't learn from books and enhanced my practical ability.
