How to make aluminum alloy toolbox

The aluminum alloy toolbox is a kind of aluminum box product, which is made of aluminum alloy and realizes the application of placing tools and measuring tools. Different from other tool boxes, this tool box has the characteristics of aluminum alloy material, light weight, easy processing and unparalleled advantages in strength. How is the aluminum alloy toolbox made? Let's take a look at the relevant knowledge of Bian Xiao! Series products include: aluminum boxes, aluminum alloy tool boxes, aluminum alloy packaging boxes, medical boxes, display boxes and other aluminum product packaging boxes. The products of Aerospace Luggage Factory include: cosmetic box, jewelry box, CD box, chip box, document password box, beauty salon, medical care box, precision instrument box, notebook computer box, clock box, toolbox, aerospace box, photographic equipment box, performance prop box and so on.

The main products are made of high-quality aluminum alloy profiles, which have the characteristics of reasonable design, firm structure and beautiful appearance. Widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other industries, is an ideal box for high-end instruments.

Maintenance of aluminum alloy toolbox

1. It is recommended to dust and clean leather products before each storage. Generally, it is best to apply leather maintenance oil on leather products first, then rub the oil on clean cotton cloth, and then wipe the surface evenly to avoid directly applying the oil on the surface to avoid damaging the leather.

2. The cabinet for storing leather products must be kept ventilated. The natural grease of leather itself will gradually decrease with time or too many times of use, so even very high-grade leather pieces need regular maintenance.

3. Aluminum alloy box is easy to oxidize, so you should pay attention to regular cleaning and pollution prevention.

Maintenance method of luggage made of other materials

When cleaning the surface of canvas, nylon, EVA and other materials, you can clean the dust on the surface with a wet cloth or viscose roller brush. When removing serious stains, you can use a wet cloth or soft brush dipped in neutral detergent to scrub. The luggage stored for a long time should be kept in a dry state to prevent the luggage from becoming moldy and producing peculiar smell.

If the box is cleaned with a damp cloth, it must be air-dried before the lid is closed. Don't use the suitcase as a storage box. If there are too many clothes stored, the roller or foot pad of the suitcase will be deformed due to the long-term overload pressure. The clothing straps and partitions in the box should be kept loose, and the elastic band will lose its elasticity if it is stretched and tightened for a long time.

Welding of aluminum box aluminum alloy toolbox

(1) Select welding wire

Generally, 30 1 pure aluminum welding wire and 31/aluminum-silicon welding wire are selected.

(2) Selecting welding method and parameters

Generally, the left welding method is adopted, and the welding gun forms an angle of 60 with the workpiece. When the welding thickness is greater than 15mm, the welding gun forms a 90-degree angle with the workpiece.

(3) Preparation before welding

Strictly clean the surface oxide film on both sides of the weld groove by chemical or mechanical methods.

Mechanical cleaning can use pneumatic or electric milling cutter, scraper, file and other tools. For thin oxide film, the oxide film can also be removed by polishing with a 0.25mm copper wire brush.

Welding immediately after cleaning. If it is left for more than 4h, it should be cleaned again.

(4) Characteristics of aluminum and aluminum alloy materials in aluminum boxes

Aluminum is a silvery white light metal with good plasticity, high electrical and thermal conductivity, oxidation resistance and corrosion resistance. Aluminum is easy to oxidize to form alumina film, and inclusions are easy to produce in weld, thus destroying the continuity and uniformity of metal and reducing its mechanical properties and corrosion resistance.

(5) Aluminum and aluminum alloy materials are difficult to weld in aluminum boxes.

Very easy to oxidize. In air, aluminum is easily oxidized to form a dense alumina film (thickness about 0. 1-0.2 micron) with a high melting point (about 2050℃), far exceeding the melting points of aluminum and aluminum alloys (about 600℃). The density of alumina is 3.95-4. 10g/cm3, which is about 1.4 times that of aluminum. The surface of alumina film is easy to absorb moisture, which hinders the fusion of basic metals during welding, and is easy to form defects such as porosity, slag inclusion and incomplete fusion, which leads to the decline of weld performance.
