Metal stamping die failure forms and countermeasures, from the four points
Metal stamping mold production after a certain period of time will appear failure, the failure form is mainly manifested in the following: wear failure, craze, deformation failure and injury (
Due to the stamping process, the working conditions of different will affect the production life of metal stamping mold, can be an analysis from the following four points: 1.
Press: press the precision and rigidity is of extreme importance to the influence of the metal stamping mold, press of high precision, good rigidity, the service life of mould is greatly increased;
Mold design: mold edge geometric parameters, the shape of the intensive, fit clearance and radius R Angle influence degree about the quality of the mould, such as mold fitting clearance, for high accuracy, can be designed smaller;
Accuracy is not high to design a few bigger, to improve die life;
Raw materials: involved in metal stamping parts, raw materials, also have a great effect to the mold, tolerance and fluctuation of raw materials and the material surface quality and rigidity, has important influence to the mold, we need to reference when design, can not exceed the scope of design required;
Mold materials: metal stamping mold raw materials quality directly affects the service life of mould, its types, related factors, such as chemical composition, hardness, different products need different mould materials to production, at the same time, hardware stamping mould materials also need to correct heat treatment process to ensure that the service life.
Above is about the metal stamping mold failure analysis and countermeasures, for your reference.
