Stamping equipment

Stamping equipment must have the following safety facilities:

⒈The stamping equipment should have nameplates, various operating instructions, safety and warning instructions;

⒉The power supply wiring should be standardized, and the equipment cables should not be damaged to prevent aging;

⒊The door lock of the distribution box on the stamping equipment should have a key, and the power supply will be automatically cut off when opening the door;

⒋Single, continuous, foot stamping and other operations should be converted by using a key-locked transfer switch;

⒌When the stamping equipment is operated in a single stroke, continuous stamping strokes shall not occur ;

⒍When continuous stroke operation is selected, a pre-control action link should be provided during the operation;

⒎The stamping equipment must have an emergency stop button and should be able to self-lock. ;

⒏There should be interlocking control between foot operation and hand operation;

⒐For transmission gears, pulleys, flywheels, levers and other transmissions exposed outside the fuselage and on the top of the fuselage Protective covers should be installed on all parts and components;

⒑ The foot pedal operation device adopts a foot pedal type, which is used for electrical switch control and can automatically reset;

⒒ The foot pedal There should be protective covers on the upper part and both sides of the plate, and the pedals should be anti-slip;

⒓ Stamping equipment must have safety protection measures to prevent hands from entering the closed area of ??the mold. The user should base on the type of stamping equipment and the shape of the workpiece produced. For different situations, safety measures for stamping operations such as automatic loading and unloading of materials, installation of safety protection devices, safety molds, and use of special tools for picking and feeding materials are adopted.

Conduct regular tests on the three tests of the electrical system (protective grounding, insulation, and withstand voltage tests), and provide test reports.

Each stamping equipment should obtain a "Stamping Equipment Safety Permit" and it should be within the validity period.
