The rapid development of the modern automobile industry has made people have higher and higher requirements for all aspects of automobiles. At the same time, the service life of automobile molds has always been an important issue of concern to enterprises. Then those reasons are the factors that affect the life of automobile molds, the following editor Tell everyone about the factors that affect the life of automobile molds.
From the failure analysis of automobile molds, it can be seen that 45% of automobile mold failures are caused by improper heat treatment. The wear, adhesion and fatigue fracture of automobile molds often occur on the surface. Therefore, the processing quality of the surface of automobile molds is very important to improve the life of automobile molds. of.
Reasonable heat treatment for different materials and different properties is a key factor to improve the service life of automobile molds. The heat treatment process should be made rigorously. The automobile mold designer must indicate the heat treatment of the parts when making self-made parts. The heat treatment effect directly affects the automobile mold. Qualification, safety and service life of automobile molds for production parts.
In addition, if the quenching temperature is too high, the parts will be quenched too hard, resulting in excessive brittleness and easy fracture and brittleness. If the temperature is not enough, the hardenability and hardenability will not meet the technological requirements, which will cause the parts to deform. Pay attention to taking protective measures, which will oxidize and decarburize the surface of automobile molds, reduce wear resistance, fatigue strength and seizure resistance, and affect service life.
The quality and performance of automobile mold materials are important factors that affect the quality, life and cost of automobile molds. In recent years, in addition to a variety of high toughness and high wear resistance cold work automobile mold steels, flame quenched cold work automobile mold steels, and powders Except for metallurgical cold-worked automobile die steel pushers.
