1、Stamping Technology 冲压工艺Blanking ( trimming): means using tooling to cut the raw material along the closing line. The cutted part is product and the remaining is scrape.冲裁：指用模具沿封闭线切板料，冲下的部分为工件，其余部分为废料。Piercing: the cutted parts is scrape and the remaining is product.冲孔：冲下的部分为废料，剩余部分为产品。Compound: bla
2、nking and piercing are finished in one step at the same time.复合：同时冲裁和冲孔。Bending: using tooling to make the raw material bended to a determinate shape.弯曲：用模具使材料弯曲成一定形状。Drawing: 1) press sheet metal to a vacant part, the thickness remains unchanged,2) raw material transformed from plane to a solid sha
3、pe. 拉深：1) 将板料压制成空心工件，壁厚基本不变，2) 材料由平面变形为 3D 曲面。Tooling Structure 五金模具的基本结构The main spare parts of sheet metal tooling are male tooling, female tooling, fixed plate, upper and lower plate, underlay, transmitting position system etc. 模具的主要零件包括：凸模、凹模、固定板、上下模座、垫板、导向定位装置等。The basic structure of sheet meta
4、l tooling can be distributed to single tooling and progressive tooling. Single tooling means one step one tooling and progressive tooling which is more efficient is usually used to produced complicated products.五金模具的基本结构可分为：单冲模与连续模。单冲模一般一次成型一个工件，连续模用于生产多工序的工件，可连续生产，效率较高。Definition for main spare par
5、ts of metal tooling 五金模具主要零件解释Male tooling: The outer protruding shape and punch of product when forming. 凸模：工件成型时的外凸型芯及冲头。Femail tooling: the inner concave shape of product when forming.凹模：工件成型的内凹型心。Fixed plate of Male tooling: used to fix punch and male tooling. 凸模固定板：固定冲头和凸模。Fixed plate of female
6、 tooling: used to fix bush and female tooling.凹模固定板：固定衬套和凸模。Offloading plate: offload the raw material from male tooling or punch, in order to avoid material scrap.卸料版：将带料从凸模或冲头上卸下，防止拉料。Underlay: hold the tooling settings.垫板：衬托模具镶件。Tooling Design 模具设计中的工艺排样1) Layout is defined as the work piece dist
7、ributing methods in the strip, sheet, or plates of the raw material, its rationalization has close relationship with the shape of workpiece.排样是指工件在条料、带料或料板上排布的方法。工件的合理布置，与零件的形状有密切关系。2) Suitable layout types can be calculated according to the difference of the shape of work piece, it can also be grou
8、ped into the categories of with-edges and non-edges.按零件的不同几何形状，可得出合适的排样类型，排样类型又可分为有搭边和无搭边二种。Post-surface treatmentGenerally, post-surface treatment for metal parts will include:degrease 除油heat treatment 热处理electrophoresis painting 电泳漆electrostatics painting 喷油silk-printing 丝印vibrate/griding/polish 研磨/抛光plating 电镀oxidization 氧化antirust 防锈e-coating with powder 喷粉
