铜片冲孔落料级进模设计
摘 要
本设计题目为铜片冲孔落料级进模模设计，体现了冲孔落料类零件的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者冲裁模设计的基础知识，为设计更复杂的冲裁模具做好了铺垫和吸取了更深刻的经验。
本设计运用冲压工艺及模具设计的基础知识，首先分析了工件的工艺要求，为选取排样的类型做好了准备；然后估算了板料的选取，便于导尺的宽度及确定排样的方法；最后分析了工件的特征，确定模具的设计参数、设计要点及自动漏料装置。
本工件为薄板的冲孔落料见，且工件的料厚较薄，所以在选取压力机是不宜过大，材料上说铜料的屈服强度也没有钢料的大，工件的尺寸较小设计时必须考虑设计一个能在冲孔落料时的剪切力小于材料的屈服强度以免冲裁力过大冲出废件。

Abstract
Blank and Prerce Grogressive Dies
This design topic hurtles bore to fall to anticipate class to enter a mold mold design for the copper, body now the blunt bore fall to anticipate a type of spare parts of design request, contents and direction, there is certain design meaning.Pass the design to the spare parts' molding tool, strengthened designed further blunt cut the foundation knowledge of[with] mold design, for design more complicated of blunt cut a molding tool to have done cushion and absorbed deeper experience.
This design usage blunt press the foundation knowledge of craft and molding tool design, analyzed the craft of the work piece a request first, have done preparation for the type that the selection lines up kind;Then the selection estimating plank to anticipate, easy to lead the method of the width and assurance row kind of Chinese foot;Analyzed the characteristic of work piece finally, make sure the design parameter, design important point of molding tool and leak to anticipate device automatically.
This work piece falls to anticipate to see for the blunt bore of lamella, and the work piece anticipate thick thinner, so Be selecting by examinations pressure machine is should not lead greatly, say on the material the copper anticipates accepts defeat strength to also have no steel to anticipate of big, the size of work piece is smaller to design have to consider to design 1 can while hurtling the bore fall to anticipate of shearing and slicing the dint is small to accept defeat strength in the material in order to prevent blunt once cut dint to rush out to discard a piece greatly.
