As a commonly used stamping method, automobile sheet metal processing can be divided into separation process and forming process. The former can separate the stamping parts from the blank along a certain contour line in the stamping process, and the quality of the separated section is also in line with the different requirements put forward by different users. The latter is to ensure that the stamping blank is not damaged, plastic deformation occurs, and changes into the required shape of the finished product, and all aspects are able to meet the requirements.

There are many places that need to use metal equipment in daily life, and the corresponding sheet metal processing industry will become more and more popular. Entering any factory with machining nature, there will always be many busy technicians who do sheet metal processing. In the pursuit of high efficiency and high output, accidents often occur due to the lack of management or the lack of safety awareness of employees themselves.

Since sheet metal processing is manually operated, the risk factor is quite high. During the construction, it is necessary to focus on and wear gloves and other protective articles. It is not allowed to operate fatigue, chat or smoke. At the same time, do not put tools, clamps and workpieces on the lathe and gearbox, so as to avoid foot injury when falling. When dealing with the iron scraps left inside the machine, special hooks should be used to solve them as soon as possible, instead of directly pulling them by hand. Place transparent baffles at suitable places to prevent splashed iron chips from touching people.

Because of the storage problem of the automobile sheet metal parts, the sheet metal processing console is placed in the basement with high humidity. After being damped, it is necessary to timely carry out moisture-proof and hygroscopic work.

Excessive wet weather will also make the surface of the console appear small water droplets, if the surface spray is not good, there will be local discoloration, more serious will lead to the breeding of mildew. But if the situation is not serious, as long as the timely ventilation shade dry. If there is already condensed water or mildew, it is necessary to clean the water first, remove the mildew with a mild detergent, and carry out dehumidification. These are common methods. Of course, if the rust is serious, it's better to go to the repair shop for repair.

In fact, the protection of sheet metal mold is also very important, so we can set up the protection plate around the mold and improve the mold. For example, reduce the dangerous area of the mold, expand the safety space and so on. On the premise of not affecting the die strength and product quality, the previous manual feeding can be improved, so as to improve the safety.
