What problems are prone to occur in the production process of automotive stamping dies
Stamping is one of the effective processes used to produce a large number of parts. In the stamping process, there are many problems with the mold, and it is a very important component of all stamping production components. Simply affect production talent and capital. Affect the entrustment cycle of the product. Mold problems must be closely focused on mold damage, product quality defects and mold sharpening, which is always troubled by professional production.
As long as these ring nodes are handled correctly. Stamping and production can handle mold problems smoothly. The problem is a very simple problem in stamping production. It usually suspends production and affects the product production cycle. Therefore, it is necessary to find out the reason for the mold and carry out reasonable repairs. Mold damage Mold damage refers to mold cracking, chipping, rising, etc., to deal with mold damage problems, it is necessary to find out the reason from the mold decision, production process and mold use.
Automobile stamping parts are the production technology of using the power of conventional or special stamping equipment to directly subject the sheet metal to the deformation force and deform in the mold, so as to obtain product parts with a certain shape, size and performance. Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology.
Among the steel products of Universal, 50-60% are made of plates, and most of them are finished products made by pressing. Car bodies, radiator fins, steam drums of steam boilers, container shells, motors, electrical iron core silicon steel sheets, etc. are all stamped and processed. There are also a large number of products in instruments and meters, household appliances, office machines, and storage utensils.
It is necessary to review whether the production material of the mold is suitable, and whether the corresponding hot embedding process is reasonable. Usually, the heat treatment history of the mold data has a great influence on it. If the quenching temperature of the mold is too high, the quenching techniques and opportunities are different, the number of tempering and the temperature, and the selection of the elbow are different, the mold will be hindered by stamping and post-production.
Unable to decide the size or depth of the blanking hole, and only cover the slot, thus damaging the blanking board. If the spring force is too small or the height is not equal, the spring will break and the cover will deflect. Forms stacked punches and damages parts. The hole punch is not installed correctly or the screw strength is insufficient. It can cause the punch to fall or break.
