In the use of stamping materials, stainless steel materials are mostly used. What should we know in advance about stainless steel stamping? To avoid unnecessary situations?
During stainless steel stamping, we need to pay attention to the situation of springback deformation of stainless steel materials. Stainless steel materials will have springback after stretching and forming. Due to the high hardness of stainless steel and the large springback of materials, when designing the molding die, we need to predict the springback value of materials to minimize the size problems caused by material
springback. Heat treatment: Many stainless steel stamping and drawing parts have higher hardness requirements, but the harder the material is, the more difficult it is to stretch. Sometimes it is necessary to conduct heat treatment after forming to meet the hardness requirements, but the stamping parts after heat treatment are prone to deformation, so the deformation amount needs to be considered in the mold design. Selection of tools: stainless steel has high hardness, which will cause relatively large loss to the tool edge of the mold. Therefore, proper selection should be made according to the hardness of stainless steel materials when selecting tools.
Selection of stainless steel stamping oil. In order to make stamping parts easy to clean, we can choose low viscosity stamping drawing oil.
In stainless steel stamping, there may be scratches on the surface, cracks on the stamping parts, and problems with the material on the die.
