The development of automobile sheet metal parts processing industry is relatively late, many enterprises' production technology is relatively backward, and the production management is not perfect. If we carefully inspect the sheet metal processing places, we will find that most of them still have potential safety hazards. Therefore, in order to ensure our personal safety, we need to know more about some noteworthy points during sheet metal processing. Here are some summary points to share with you:

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

In addition to the basic protection mentioned above, safety measures should also be taken in specific sheet metal processing procedures, including sheet metal cutting, bending and punch operation. Now sheet metal cutting almost all uses laser cutting, the injured may be eyes, so we should wear professional protective glasses. As for shear bending, we know that some non-metallic materials, such as hard steel and alloy steel, are not suitable for cutting by shearing machine, so we should avoid the processing of such materials. It is also very important to check the blade edge. When it is found that the blade edge is notched or blunt, it should be polished or replaced in time to avoid affecting the working efficiency or even damaging the material. After the punch operation, the necessary labor protection articles should also be worn. Before starting the machine, it is also necessary to check whether there is sliding or displacement in the connection, lubrication and other parts of the machine. The operation can only be started after the screws of each device are firm.

Design principles of sheet metal parts:

(1) the designed sheet metal parts shall meet the requirements of product application and technical functions, and be easy to assemble and repair

(2) the designed sheet metal parts are necessary to improve the utilization rate of metal materials, reduce the varieties and standards of materials, and reduce the consumption of materials as much as possible. In the case of promise to choose low-cost information, as far as possible to make the parts do not waste and less waste blanking

(3) it is necessary for the designed sheet metal parts to have simple shape and reasonable structure, so as to simplify the mold structure and process quantity. That is to say, the minimum and simple stamping process is used to complete the processing of all parts, and other methods are used to reduce the processing. It is also conducive to the stamping operation, the arrangement and completion of mechanized and automatic production, so as to improve the labor production rate

(4) when the designed sheet metal parts can be used normally, try to make the requirements of dimensional accuracy level and surface roughness level lower, and it is conducive to the exchange of products, reduce waste products, and ensure the safety and stability of product quality

(5) the designed sheet metal parts shall be able to use the existing equipment, technical equipment and technical process to process them as much as possible, and be conducive to the extension of the service life of the stamping die.
