According to the data of Pacific Auto Network, the drawing die for automobile die panel is a common die with high geometric complexity and complex internal structure layout in rubber industry. In order to ensure the quality and life of automobile die panels, it is necessary to test their hardness. Hardness tester is a widely used hardness testing tool.
Hardness design method: firstly, select a suitable hardness tester, select the corresponding type of indenter according to the thickness and hardness range of the tested material, and install it on the hardness tester. Then, according to the standard test requirements, the indenter of the hardness tester is pressed into the surface of the tested material, and the hardness and quality of the drawing die for the automobile die panel are judged according to the numerical values displayed by the test instrument.
