在模具结构、使用条件一定的情况下,合理选用模具材料及热处理工艺是提高模具使用寿命的重要途径。现就我厂在这两方面所做的一点工体介绍于下。一、模具失效方式及影响使用寿命的因素冷冲模具在工作中主要失效方式为磨损、过量的塑性变形、疲劳、断裂。失效原因的百分比示于表1。从表可见,模具寿命是一个综合性问题,虽然热处理问题占模具
In the mold structure, the use of certain conditions, the rational use of mold materials and heat treatment process is to improve the service life of the mold an important way. Now I plant in these two aspects of the body made a little introduction below. First, the mold failure mode and the factors that affect the service life Die in the work of the main failure mode for wear and tear, excessive plastic deformation, fatigue, fracture. The percentage of failure causes is shown in Table 1. As can be seen from the table, die life is a comprehensive problem, although heat treatment problems accounted for mold
