What are the failure forms and countermeasures of metal automobile stamping parts molds?

Hardware automobile stamping parts die will also fail after a certain period of production. The failure forms are mainly manifested in the following points: wear failure, crack failure, deformation failure and gnawing failure (collapse edge); due to different stamping processes, the working conditions vary. Differences will also affect the production life of metal stamping molds, which can be analyzed from the following 4 points:

  • 1. In terms of press: the accuracy and rigidity of the press are extremely important for the metal stamping die. The press has high precision and good rigidity, and the life of the die is greatly improved;
  • 2. In terms of mold design: the geometric parameters of the mold edge, the shape of the convex and concave mold, the fit clearance and the R angle radius all have an impact on the quality of the mold, such as the mold fit clearance, for those with high precision requirements, it can be designed to be smaller; If the requirements are not high, it can be designed to be larger to improve the life of the mold;
  • 3. Raw materials: When it comes to the raw materials of metal stamping parts, it also has a great impact on the mold. The tolerance and fluctuation of the raw materials, as well as the surface quality of the material and the rigidity of the material, all have an important impact on the mold. It is necessary to refer to it when designing. It cannot exceed the range required by the design;
  • 4. Mould raw materials: The quality of the raw materials of metal stamping parts directly affects the service life of the mould. Its type, chemical composition, hardness and other factors are related. Products with different requirements require different mould materials to produce. At the same time, metal stamping parts Mold raw materials also require the correct heat treatment process to ensure service life.
