三角形水阀垫片倒装复合模设计与加工
摘 要
本文设计的是冲孔、落料、复合模,模具结构比较简单实用,使用方便可靠。因为模具生产大批量的生产,而且模具可以保证冲压产品的尺寸精度和产品质量,模具的设计与加工主要考虑到模具的设计能否满足工作的工艺性设计,能否加工出合格的零件,以及后来的维修和存放是否合理等。在本次设计中除垫片孔的精度外更重要的是外圆圆角尺寸精度,不仅要考虑做出的零件能满足工作要求,还要保证它的使用寿命,最后加工出三角形水阀垫片冲压模具模型产品一套。

This article is designed punching, blanking, Progressive Die, Die practical examples of relatively simple structure, easy to use and reliable. Stamping die mainly of sheet metal forming have been separated or parts of the processing methods. Because the production of large quantities of mold manufacturing, mold and stamping products to ensure dimensional accuracy and quality of products, Die Design and Manufacture of the main mold design, taking into account the work of the process can meet the requirements of design, can be processed into qualified parts, as well as subsequent maintenance and storage, such as is reasonable. In the design of the gasket hole accuracy is more important outside the outer fillet size precision, not only have to consider so that the parts made to meet the job requirements, but also to ensure his life. the card order process, non-standard parts of the process of card processing technology.
