Introduction of Kunshan Ruizhengyuan Electronics: What are the safety precautions in stamping process?

The core of stamping safety is "preventing mechanical injury+controlling process risk+observing operation specifications", which needs to be avoided from equipment, operation, environment and other aspects. The key points for attention are as follows:

1. Equipment safety protection is in place

Stamping equipment must be equipped with qualified safety protection devices, such as photoelectric protection devices, two-handed operation buttons, fences, feeding manipulators, etc., and it is strictly forbidden to dismantle or shield them.

Check the clutch, brake and emergency stop button of the equipment regularly to ensure sensitivity and reliability, and the single stroke mode is preferred for manual feeding scenes.

When installing, debugging or maintaining the mold, the power supply must be cut off and a warning sign "No Closing" must be hung to avoid wrong start.

2. Strictly implement the operation specifications.

Operators need professional training and be familiar with the performance of equipment and dies. It is forbidden to work without a license or operate illegally (such as one-handed operation and overstroke stamping).

Special tools (such as tweezers, suction cups and push rods) should be used for manual feeding/fetching, and it is forbidden to directly reach into the mold closing area by hand.

It is forbidden to clean up the iron filings, adjust the mold or measure the workpiece during the operation of the equipment, and it is necessary to stop the machine and confirm the safety before operation.

3. Mold and process safety control

The mold needs to be checked for strength, so as to prevent parts from splashing and hurting people due to the crack and edge collapse of the mold, and regularly check the sharpness of the mold edge and the tightness of fasteners.

Reasonably set the stamping process parameters to avoid overload and overspeed operation, and prevent the material from jamming the die or the workpiece from ejecting.

When stamping thin and soft materials, it is necessary to prevent the material from wrinkling or rebounding to hurt people; Before stamping thick materials, it is necessary to confirm that the materials are placed firmly to avoid deviation.

4. Personal protection and environmental management

Operators must wear qualified labor protection articles, such as cut-proof gloves, protective glasses and safety helmet. Loose clothes and jewelry are strictly prohibited, and long hair should be put into the working cap.

Keep the operation area clean and tidy, and clean up the iron filings and wastes in time to avoid tripping or scratching; The passage is clear, and there is no obstacle blocking the emergency exit and equipment operation space.

Keep sufficient light in the working environment, so as to facilitate the observation of the stamping process and avoid operation errors caused by poor sight.

5. Emergency treatment and daily maintenance

Be familiar with the position of the emergency stop button of the equipment. In case of material jam, abnormal sound and equipment failure, stop the machine immediately and cut off the power. It is forbidden to start the machine forcibly.

Regularly maintain the stamping equipment, lubricate the key parts, check whether the circuit and hydraulic system are normal, and avoid the equipment running with diseases.

Establish an emergency plan for safety accidents, and conduct emergency drills regularly to ensure that operators master the handling methods of unexpected situations such as electric shock and mechanical injury.
