Description
Technical Field
[0001] The invention relates to the technical field of automobile stamping parts performance detection, and in particular to an automobile stamping parts performance detection device. Background Art
[0002] Automotive stamping parts refer to automotive parts manufactured through the stamping process. Stamping is a metal forming process that usually involves placing metal sheets in a mold and using a punch or press under high pressure to shape the sheet into the desired shape. This process can produce parts of various complex shapes and has high production efficiency.
[0003] There are many types of automobile stamping parts, among which anti-collision beam is one of them. It is an important part of the automobile safety system. It is mainly used to absorb and disperse the energy during collision and protect passengers and vehicle structures from serious damage. Therefore, the collision strength performance testing of automobile anti-collision beams after production is very important.
[0004] The existing collision detection of anti-collision beams only conducts various types of tests such as frontal collision, side collision and rear collision on the anti-collision beam itself. However, in actual collision scenarios, the type of collision object will also affect the collision strength performance of the anti-collision beam. The collision detection that only adjusts the position of the anti-collision beam itself is not accurate enough. It is impossible to test whether there are many changes in the collision strength of the anti-collision beam for piles of different thicknesses. At the same time, for the pile, different collision effects will be produced when it is tilted. This shows that the existing technology has certain defects in the detection method. For some special on-site scenarios, it is difficult to evaluate the collision strength of the anti-collision beam. Summary of the invention
