What are the safety operation specifications for metal stamping?

The safety operation specifications for metal stamping should focus on five cores: equipment operation, mold management, material handling, personnel protection and emergency treatment, and prevent mechanical injury, material flying out, mold cracking and other safety accidents. The specific specifications are as follows:

Safety preparation before equipment operation

Before operation, it is necessary to check whether the clutch, brake, slider and safety protection device (safety grating and two-hand start button) of the stamping equipment are sensitive and effective, whether the oil pressure of the hydraulic system is stable, and whether the electrical circuit is damaged. Only after confirmation can the machine be started.

Clean the equipment workbench and surrounding area, remove irrelevant sundries and tools, and ensure the smooth passage; Check whether the die is firmly installed, and the male die and female die are accurately aligned, so as to avoid displacement or cracking during stamping caused by loose die.

Wear personal protective equipment (PPE): You must wear anti-impact goggles and anti-static gloves (cotton gloves are strictly prohibited to prevent you from being involved in the equipment), long hair should be put into a working hat, and loose clothes and slippers are not allowed to go to work.

Safe operation in equipment operation

Strictly implement the two-hand start operation: during a single stamping, it is necessary to press the start button with both hands at the same time, and it is strictly forbidden to operate with one hand or use tools instead of the hand trigger button; Before continuous stamping, it is necessary to confirm that the safety grating is unobstructed and no one is near the die area.

Feeding and taking parts should be standardized: use special tools (such as tweezers, suction cups, feeders) to operate, and it is forbidden to put hands or body parts into the closed area of the mold; Automatic feeding device is preferred for small parts stamping to avoid manual close contact with dangerous areas.

Illegal operation is strictly prohibited: when the equipment is running, it is not allowed to adjust the mold, clean up the waste and wipe the slider; If abnormal sound, stuck slider and loose mold are found, you need to press the emergency stop button immediately, and then check the fault after cutting off the power supply. It is forbidden to run with fault.

Multi-person collaboration requires a clear division of labor: one person is responsible for operating the equipment and the other is responsible for material delivery, and fixed gestures or passwords should be used for communication to avoid misoperation; Non-operating personnel are strictly prohibited from approaching the stamping station.

Safety code for mold replacement and maintenance

Before replacing the mold, the main power supply of the equipment must be cut off, and a warning sign of "Equipment maintenance, no closing" should be hung to prevent others from starting it by mistake; Use a special spreader when disassembling the mold, and lift it gently to avoid the mold from falling and hurting people.

When installing the mold, it is necessary to calibrate the positioning pin and guide post to ensure the uniform gap of the mold, and the fastening bolt should be tightened with a torque wrench; After the installation is completed, manually turn the car to test the stroke of the slider, and confirm that there is no interference and no jamming.

When the cutting edge of the mold is passivated or stuck, it needs to be dismantled and polished after stopping, and it is strictly forbidden to directly knock the mold on the equipment; Mold maintenance needs to be coated with antirust oil and stored in special shelves to avoid stacking and squeezing.

Safety requirements for material and waste disposal

Rolled materials and sheets shall be neatly stacked, and the height shall not exceed 1.2m to prevent collapse; Use forklift or crane when handling materials, and manual handling of overweight plates is strictly prohibited.

The waste generated by stamping should be cleaned up in time and put into a special waste box to avoid the accumulation of waste in the workbench or die, which will cause the die to get stuck or the waste to splash and hurt people.

The finished products should be placed in layers with anti-static trays, and should be handled with care to avoid sharp corners from scratching people.

Emergency treatment and daily management norms

Be familiar with the position of the emergency stop button. In case of mold sticking, material flying out, personal injury and other accidents, press the emergency stop button at the first time to cut off the power supply and report it to the person in charge at the site.

In case of personal injury, stop operation immediately, take first-aid measures (such as hemostasis and dressing), and send them to hospital for treatment; At the same time, protect the scene of the accident and cooperate with the investigation and analysis of the reasons.

Regularly carry out safety training and emergency drills, and the operators must hold relevant certificates; After the daily operation, turn off the power supply and air supply of the equipment, clean the workbench, and record the operation of the equipment.
