限位板冲压成形工艺与模具设计摘 要：本设计题目为限位板冲裁模，体现了典型冲裁模的设计要求、内容及方向，有一定的设计意义。通过对该模具的设计，加强了设计者对冲裁模设计基础知识的理解和运用，为设计更复杂的冲裁模具做好了铺垫。本设计运用冲裁工艺及模具设计的基础知识，首先分析了板材的性能要求，为选取模具的类型做好了准备；然后计算了冲裁件的冲裁力，便于选取压力机吨位及确定压力机型号；最后分析了冲裁件的特征，便于确定模具的设计参数、设计要点及卸件装置。本设计采用了冲孔落料级进模成形垫片。成形原理可划分为两个阶段：首先冲孔凸模与凹模共同作用先冲出四个30mm的孔，而后利用第一步冲出的30mm的孔做精确定位使外形凸模与凹模共同作用使工件落料成形。关键词：限位板、 压力机、 级进模具、 冲孔、 落料Stamping process and die design of limit plankAbstract:This design topic hurtles to cut a mold for the limit plank, body now the typical model be blunt to cut design request, contents and direction of mold, there is certain design meaning.Pass the design to that molding tool, strengthenned a design to comprehension and usage which hurtles to cut the mold design foundation knowledge, for design more complicated of blunt cut a molding tool to have done cushion.This design usage is blunt to cut the foundation knowledge of craft and molding tool design, the function which analyzed a plank material first request, have done preparation for the type which selects by examinations a molding tool;Then computed to hurtle to cut a piece of blunt cut dint, easy to selection pressure machine tonnage and assurance pressure model number;Finally analyzed blunt cut the characteristic of piece, easy to assurance molding tool of design parameter, design important point and unload a device.This design adopted blunt bore-fall to anticipate class to enter a mold to take shape a mat slice.Take shape the principle can divide the line to two stages:Blunt bore convex mold rushes out 4 first with cave mold common function first the bore with 30 mms, and then make use of square one to rush out of the bore with 30 mms do an accurate fixed position to make the shape convex mold and cave mold common function to make a work piece to fall to anticipate to take shape.Keyword:The
