Metal stamping is a process that uses punches and dies to deform or break stainless steel, iron, aluminum, copper and other plates and other materials to have a certain shape and size.
Is metal stamping dangerous? I often see people asking this question in some metal stamping posts and forums. Why are there so many people asking about this kind of question or similar questions? Mainly because of the repeated occurrence of stamping injuries. People have subconsciously thought that stamping is a highly dangerous job, so is stamping really that dangerous? Why do injuries often occur?
Metal stamping processing is dangerous, but it is not really that dangerous. As long as there is a stamping incident, there is a reason. On the one hand, it is the reason for the stamping plant, and on the other hand it is the reason for the operation of the workers. As long as you do well in these two aspects, follow the stamping processing system, and operate properly, stamping is still very safe.
1. Matters that the factory should pay attention to
When a factory operates a punch press, how can it not be guaranteed that the punch press is fully qualified, and where does safety start? The main requirements for equipment are as follows:
1. The punch press works well
A good punch is the foundation of safe production. The lubrication of the punch must be normal; the copper bushes must not be excessively worn; the tightness of the brake must be within the normal range; the clutch and control system are flexible; the bolts of each part must not be loose;
2. Install safety grating
After the safety grating is installed, if the puncher's hands or other items that affect safety enter the dangerous area, the punch will be stopped in an emergency; in the shutdown state, the punch cannot be started. The picture below is a punch with safety grating
3. Reasonable switch design
It is necessary to design two start switches and an emergency stop switch, and the two start switches must be a certain distance apart, as long as the stamping worker presses the two start switches at the same time to start the machine; the emergency stop switch cannot be too far away from the stamping worker. Otherwise, when a situation arises, the worker cannot stop the punching machine for the first time.
4. The design of stamping die is reasonable
If the punch is the first element of safe production, then the stamping die is the second element. The production of stamping parts relies on stamping dies, so whether the design of stamping dies is reasonable plays a vital role in safety. Whether it is convenient to discharge and return the material smoothly all affect the safety of the factory during operation. When designing the mold, it must be possible to ensure that the factory can easily use tools to unload and unload.
5. Safety tools must be used
During the stamping process, it is absolutely forbidden to let the hand enter the working area of the mold, which requires the use of safety tools to complete the unloading and unloading work. The safety tools that are often used nowadays are magnet type, suction cup type and tweezers.
6. Establish a safety management system and punch operation manual
Stamping factories must carry out safety training for stamping workers from time to time, so that the concept of safe production can be deeply rooted in the hearts of the people. Help stampers to establish safe operating habits.
Second, the matters that stamping workers should pay attention to
1. Maintain a good mental state
When operating the punch, you must maintain a good mental state, and you must not operate the punch when the mental state is not good. If you have any concerns, you must ask the factory for leave or transfer to another position.
2. Ensure concentration
In the process of work, you can't talk to others, let alone look at your cell phone or make and receive calls. Nor can they engage in anything that has nothing to do with the operation of the press.
3. Calm attitude
When the material is not discharged smoothly or the product is stuck in the mold, you must calmly stop the machine and do not be impatient.
4. It is strictly forbidden to enter the work area with hands
Ninety percent of accidents involving punching machines are caused by workers entering the work area with their hands. Under no circumstances should their hands enter the work area. This is the first guarantee of safety for stamping workers! Manual safety tools must be used!
5. Learn the company's safety regulations and operating manuals
Frequently learn the safety production specifications and systems formulated by the company to establish safety production awareness.
As long as you operate and pay attention to the above introduction, metal stamping is actually not that dangerous.
