how to carry out cold stamping materials for sheet metal processing? What are the requirements for cold stamping materials? How to carry out cold stamping materials for sheet metal processing? At present, the competition in the sheet metal processing market is quite fierce, and many aspects are very demanding at the technical level. The following is a proposal for everyone.

sheet metal processing parts have certain regulations for processing materials. first, let's look at the relevant requirements for the mechanical properties of materials in cold stamping. The mechanical properties of materials are a critical indicator determining whether stamping operations can produce qualified parts.

for the deformation process, the plasticity of the material is very high. generally speaking, under a certain strength, the better the plasticity of the material, the greater the level of deformation allowed, and the better the stamping process. For the separation process, it is specified that the material has appropriate plasticity. If the plasticity is too high and the material is too soft, the burr height allowed by the dimensional accuracy of the blanking parts is difficult to meet the specified requirements. If the plasticity of the material is too low, the material is too hard and brittle, although the stamping process is better, it will reduce the use of the mold. Because of this, the plastic index of mechanical properties of materials is of great significance in cold stamping production.

In addition, the yield ratio of the material and the obvious level of cold work hardening of the material should be selected according to different stamping.

knowledge expansion:

with the progress of the times and the progress of science and technology, the field of sheet metal chassis cabinet is also widely used in various fields and fields, and the sheet metal chassis cabinet itself can be used as an electrical conductor. But this situation is not certain.

Sometimes, we need to ensure that certain parts of the electronic chassis cabinet are insulated. Therefore, the insulating material, epoxy board or epoxy rod selected according to the drawing needs to be soaked in insulating paint and dried. The resistance insulation value of the positive and negative copper bars of the cabinet to the rack is ≥ 100MΩ (when the ambient temperature is 25 ℃ ± 2 ℃, the relative humidity is 90%, and the DC voltage is 500V). The cabinet goods that have been processed in that way can basically ensure insulation.
