模具原材料的控制应从以下几个方面进行:
  The control of mold raw materials should be carried out from the following aspects:
  1、宏观检查化学成分以确保钢的性能是决定性的,但合格的成分,不能完全解释钢的性能,因为钢的内部组织和成分的不均匀性,宏观检查在很大程度上补充这方面的缺陷。宏观测试可以观察到钢的结晶、钢的连续性破坏和某些成分的不均匀性。标准《结构钢低功率组织缺陷评定图》GB1979
  1. Macroscopical examination of chemical composition to ensure the performance of steel is decisive, but the qualified composition cannot fully explain the performance of steel, because of the inhomogeneity of internal structure and composition of steel, macroscopical examination to a large extent complements the defects in this respect. The macroscopical test can observe the crystallization of steel, the continuous failure of steel and the inhomogeneity of some components. Standard "assessment drawing of structural steel low power structure defects" gb1979

  宏观常见8种缺陷:偏析、疏松、夹杂、收缩、气泡、白斑、裂纹、褶皱。模模具
  There are 8 kinds of defects in macrostructure: segregation, looseness, inclusion, shrinkage, bubble, white spot, crack and fold. Die
  退火的目的是降低钢的硬度,便于加工,为后续的热处理做好组织准备。根据GB1298一级评定图对碳钢工具钢的退火组织进行了评定。
  The purpose of annealing is to reduce the hardness of steel, to facilitate processing and to prepare for the subsequent heat treatment. The annealing structure of carbon steel tool steel was evaluated according to the first grade evaluation chart of gb1298.
  Cr12型leitstenitic钢组织中含有大量共晶碳化物,碳化物的不均匀性对使用性能有非常重要的影响,因此必须严格控制碳化物的分布。综上所述,由于模具工厂和车间生产对象是乏味的,单件和小批是多少,模具生产定额制定和管理带来一定难度,加上GeChang和车间生产方法、设备、技术、质量是不同的,所以,在做配额必须根据我们的工厂和车间的实际情况,找出合适的方法来开发先进和合理的任务时间,以提高劳动生产率。
  There are a lot of eutectic carbides in the structure of Cr 12 type leistentitic steel. The non-uniformity of carbides has a very important influence on the service performance. Therefore, the distribution of carbides must be strictly controlled. To sum up, due to the tedious production objects of mold factories and workshops, the number of single piece and small batch, the difficulty in the formulation and management of mold production quota, and the difference between GeChang and workshop production methods, equipment, technology and quality, we must find out appropriate methods to develop advanced and reasonable task time according to the actual situation of our factories and workshops, To improve labor productivity.
