冷冲压生产在国民经济中占有重要地位,在汽车拖拉机制造、电机、电器、仪器仪表和无线电行业,以及日用五金、玩具等部门冲压件都占着相当大的比例。当前在冷冲压生产中存在的主要问题是模具的设计制造,无论在数量上和质量上都远远不能满足生产发展的需要。因此积极开展模具标准化工作,推广使用冷冲模标准件及技术条件,是便于模具集中生产,简化模具设计工作量,缩短模具设计和制造周期,降低模具成本,提高模具质量的有效 Cold stamping production occupies an important position in the national economy and occupies a large proportion of stamping parts in automobile tractor manufacturing, electrical machinery, electrical appliances, instrumentation and radio industries as well as daily hardware and toys. At present, the main problem existing in the cold stamping production is the design and manufacture of the mold, which is far from being able to meet the needs of production development both in quantity and quality. Therefore, to actively carry out mold standardization, the promotion of the use of standard parts and technical conditions of cold stamping is to facilitate the production of molds to simplify the workload of mold design and shorten the mold design and manufacturing cycle, reduce mold costs and improve mold quality effectively
