Stamping mould in the production process will often wear, so how to improve the durability of stamping die? Cold stamping mould is a necessary process equipment in the production process of metal stamping parts. The quality of the mould plays a decisive role in improving the quality of the product, extending the life of the product and improving the production efficiency. However, because the metal stamping parts mould in the production process because of often wear and tear and lose the operating scale, resulting in difficult to meet the production needs. Therefore, improve the durability of stamping mould is very important, today Xiaobian sorted out a few useful solutions for us to study and discuss:
Improve stamping mould planning
Whether the cold stamping mould planning is reasonable is the foundation of improving the stamping mould durability. Therefore, in the planning of stamping mould to take an effective approach to adverse conditions in the product forming, to improve the durability of stamping die, such as planning the life of small hole stamping mould is often shown in the punching hole on the punch. About the metal stamping parts die, in the planning should make the fine punch as far as pos
sible to shorten its length, to add strength, together, should also use the guide sleeve method to strengthen the fine punch protection. In addition, in the stamping mould planning, should take full account of the mold frame, convex and concave mould fixed method and guide way, the confirmation of the pressure center and the upper and lower template rigidity and other factors. Especially for the blanking die, the choice of void value has a great impact on durability. In the planning, the gap of the stamping mould should be selected reasonably, and the gap value can not be too small, otherwise it will affect the service life and durability of the stamping die. Practice has proved that, without affecting the quality of the stamping parts, the appropriate enlargement of the gap can greatly improve the durability of the stamping die, sometimes even several times and dozens of times.
Correct selection of stamping mould data
Different stamping mould data have different strength, endurance and wear resistance. Under certain conditions, the use of advanced materials can improve durability several times. Therefore, in order to improve the durability of the stamping die, it is necessary to choose good information.
1) the thick steel plate (the typical case punching shear thickness is 35mm steel plate), stainless steel plate, and non-ferrous metal plate stamping molding die, the more typical is the air conditioning fin die, etc..
2) drawing mold, stainless steel drawing mold.
3) cold extrusion die. Cold extrusion 304 stainless steel, thickness of 0.5mm or more, instead of DC53 and other materials, the effect is very good.
4) large stamping templates with high scale stability requirements.
Reasonable casting and heat treatment of stamping mould parts
In the selection of high quality stamping mould information together, on the same material and different properties of the information requirements of reasonable casting and heat treatment, is one of the main ways to improve the durability of stamping die. For example, when quenching, if overheating is produced during heating, it will not only make the workpiece too brittle, but also cause deformation and cracking when cooling simply, so that the durability is reduced. Therefore, in the manufacture of stamping die, it is necessary to grasp the heat treatment process.
