用 Cr4W2MoV 钢代替 Cr12MoV 钢制造高质量的冷冲压模具,经过几年来有关单位试验和生产应用证明性能良好,是一种较好的钢种。热处理变形问题是模具制造中众所关心的问题,Cr4W2 Mo V 钢能否在这方面代替 Cr12Mo V 钢制造形状复杂、变形要求严格的模具,也是一项十分重要的性能指标。为摸索 Cr4W2MoV 钢对比热处理变形的一般规律,以及和 Cr12MoV 钢对比热处理变形的大小,我们结合我厂模具生产及热处理工艺特点,采用三种不同形状的变形试样及模具模拟试样,在不同淬火、同火、冷却等工艺参数条件下进行试验。
With Cr4W2MoV steel instead of Cr12MoV steel manufacturing high-quality cold stamping die, after several years of relevant unit test and production applications prove good performance, is a better type of steel. Heat Treatment Deformation is the mold manufacturing issues of great concern, Cr4W2 Mo V steel in this regard can replace the Cr12Mo V steel to create complex shapes, deformation-demanding mold, but also a very important performance indicators. In order to explore the general rule of heat treatment deformation of Cr4W2MoV steel and compare with the heat treatment deformation of Cr12MoV steel, we combined the characteristics of mold production and heat treatment in our factory with three different deformation samples and mold simulation samples. , With the fire, cooling and other process parameters under the conditions of the test.
