墊板沖裁模設計
摘要: 墊板——沖孔落料級進模設計。通過分析制件的工藝性可確定制件的成形加工需要一副模具完成。在一副連續(xù)模中，可以完成包括沖裁，彎曲，拉伸和成形等多道沖壓工序。相對其他冷沖壓模具結(jié)構(gòu)而言，它具有以下一些優(yōu)點：
① 工件加工精度較好，尺寸精度較高，并且模具壽命較長；
②生產(chǎn)效率高，凸凹模不受到最小壁厚的限制。但需考慮的問題是：模具零部件加工制造比較困難，成本較高，并且受條料外形尺寸的精度限制較大。

Pad progressive die design
Abstract:The support turns the piece- the blunt bore falls to anticipate just progressive die design.The craft that passes the analysis system piece can make sure to make the piece to take shape to process to need one molding tools to complete.one progressive die should complete blanking, bending,deawing and forming and so on. Opposite and other cold hurtle to press the molding tool structure but speeches, it has following some advantageses:
The ① work piece is together the stalk degree is better, the size accuracy is higher and the mold’s worktime longger;
The ② produces the efficiency high, the convex and cave mold is not subjected to the thick restrict of minimum wall. But need the problem of the consideration is:The molding tool zero partses process the manufacturing more difficulty, the cost is higher, and be subjected to the anticipates the shape size of accuracy limit bigger.
