Stamping plant on stamping die working parts material requirements
Release time:
2023-11-15
Stamping factory put forward requirements on the stamping die working parts material requirements stamping die working parts material requirements: stamping die work to withstand impact, vibration, friction, high pressure and tensile, bending and torsion loads, even at higher temperatures (such as cold extrusion), complex working conditions, prone to wear, fatigue, fracture, deformation and other phenomena. Therefore, the requirements for the material of the working parts of the mold are higher than those of ordinary parts. Due to the different working conditions of various types of stamping dies, the requirements for the materials of the working parts of the die are also different.
Among all the mold failure factors, the material and heat treatment of the mold account for about 70%, which has become the main factor affecting the life of the mold.
Therefore, in the entire design and manufacturing process of the mold, the selection of mold materials and heat treatment process is particularly important.

1. Blanking die material requirements for sheet metal blanking die working parts of the material requirements with high wear resistance and hardness, and the thick plate blanking die in addition to the requirements with high wear resistance, compressive yield point, in order to prevent die fracture or chipping, should also have high fracture resistance, high bending strength and toughness. 2. The requirements of the drawing die material require the die working parts material to have good adhesion resistance (anti-seizure), high wear resistance and hardness, certain strength and toughness, and good cutting performance, and the deformation during heat treatment should be small. 3. The requirements of cold extrusion die materials require that the working parts of the die have high strength, hardness and high wear resistance. In order to avoid impact fracture, it also requires a certain degree of toughness. Due to the extrusion will produce a larger temperature rise, it should also have a certain degree of thermal fatigue resistance and thermal hardness. According to the requirements of the stamping die working parts material, the reasonable selection of mold materials and the implementation of the correct heat treatment process is the key to ensure the life of the mold. For different uses of the mold, according to its working state, stress conditions and the performance of the processed materials, production batch and productivity and other factors, and the above requirements of the performance of the focus, and then make the choice of steel and heat treatment process.
