第一节概况冷挤压模具的设计和制造的好坏,直接影响到冷挤压的成败,冷挤压模具可分为模具的工作部分(凸、凹模、顶杆等)和紧固部分,后者即为通用模架。冷挤压模具的制造,特别是工作部分的制造,对于模具的使用寿命起很重要的作用。其模具材料的选择、毛坯的锻造、热处理、切削加工都是关键的环节,尤其对于大批生产用的模具,在这些方面都要给以很大注意。对于模具工作部分的设计制造,一个总的原则是要求过渡圆滑,避免突变,使尽可能 Section 1 Overview Cold extrusion die design and manufacture of a direct impact on the success of cold extrusion, cold extrusion die can be divided into the working part of the mold (convex, die, ram, etc.) and the fastening part , Which is the universal mold base. Cold extrusion die manufacturing, especially the manufacture of the working part, the life of the mold plays a very important role. The choice of mold materials, rough forging, heat treatment, cutting are the key aspects, especially for a large number of production molds, in these areas have to give a lot of attention. For the mold part of the design and manufacture, a general principle is to require a smooth transition to avoid mutation, so as possible
