At the same time, some basic principles are put forward to ensure the perfect forming of stamping parts. At the same time, it is also to improve the work and reduce the production cost. What are the specific issues?
No matter what the purpose of stamping parts, material selection try to use ordinary materials instead of valuable materials, the common way is carbon steel instead of alloy steel. Colleagues try to use thinner sheet metal as much as possible, but they have to use the compression rib structure in the parts with weak stiffness, so as to reduce the material cost and the impact pressure.
In the aspect of shape design of stamping parts, simple and symmetrical shape should be adopted as far as possible, so as to balance the force on the blank during stamping, which is of great help to simplify the processing procedure and improve the work efficiency. Another point is that the accuracy of stamping parts should not be too high, otherwise it will increase the finishing process and extend the production cycle of the workpiece.
More and more attention has been paid to the automotive stamping industry, which is due to the continuous development of the industry. In order to ensure that all aspects of automotive stamping parts meet the standards, it needs to be inspected. The corresponding inspection method is basically the same as other products, and the inspection of defects and hardness should be emphasized in many inspection items.
There are many forms of defects in stamping parts, including crater, pitting, scratch, cracking, wrinkling, deformation, missing hole and so on; Secondly, special inspection tools must be used skillfully; There are also samples.
Because the main material of automobile stamping parts is die steel, so as long as the difference between its initial speed and rebound speed is tested, the hardness value of the sample can be determined. Moreover, due to the different thickness of the surface layer of the stamping parts, the results must be different.
