第二部分现代冷冲模新技术简介在现代冲压工艺中,许多项目都离不开模具的技术改进和模具的现代化。据统计,约有70％金属零件的粗加工和50％的精加工,由过去切削加工完成的工序,可由模具来完成。所以说,现代化的模具是各种加工工序的集中表现,是现代冲压工艺的核心。模具的制造周期,制造精度和使用寿命等直接影响产品的质量、数量和成本,也影响产品的更新换代。在使用模具最广泛的电子、仪器仪表、轻工、航天航空和汽车等工业中,模具的品种发展最快,模具的先进程度较高,各种模具新技术也都在
The second part of the modern technology introduction of new technology in modern stamping stamping process, many projects are inseparable from the mold of technical improvements and mold modernization. According to statistics, about 70% of rough metal parts and 50% of finishing, the process completed by the past, can be done by the mold. Therefore, the modern mold is a concentrated expression of various processing operations, is the core of modern stamping process. Mold manufacturing cycle, manufacturing accuracy and service life directly affect the quality of the product, quantity and cost, but also affect the replacement of the product. In the use of the most widely used mold electronics, instrumentation, light industry, aerospace and automotive industries, the fastest growing varieties of molds, mold a higher degree of advanced, all kinds of new mold technology are also in
