内容简介：

支架冲压工艺及模具设计摘要本设计题目为Z形弯曲模设计，体现了典型Z形弯曲模的设计要求、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对弯曲模设计的基础知识的了解与掌握，为设计更复杂的弯曲模具做好了铺垫和吸取了更深刻的经验。本设计运用弯曲成型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；然后计算了弯曲件的弯曲力，便于选取压力机吨位及确定压力机型号；最后分析了弯曲件的特征，确定模具的设计参数、设计要点及顶出装置的选取。本设计采用了组合上下模成型Z形件，这种结构能有效的防止坯料的偏移，成形机构动作灵活可靠，设计方便，非常适合在本副模具中使用。关键词：弯曲模 组合凸模 组合凹模 Piank flection of models the foundation and the moiding tool desingAbstractThis design topic is a Z form flection the mold design, body now the typical model Z form flection mold of the design request,contents and direction, there is certain design meaning.Foundation knowledge passed the design to the spare parts molding tool, strengthenned the design flection a mold a design further, for design a more complicated bent molding tool to have done cushion and absorbed deeper experience.This design usage flection models the foundation knowledge of the craft and the molding tool design, analyzing the function request of the plank material first, having done preparation for the type that selects by examinations a molding tool;Then compute the bent dint of the bent piece, the easy to selection pressure machine tonnage and make sure pressure model number;Analyzed the characteristic of the bent piece finally, make sure the design parameter of the molding tool and design the important point and crest selection for equip.This design adopted the combination top and bottom mold to model a Z form piece, this kind of structure can keep from anticipate effectively of be partial to move, take shape organization to act vivid credibility, design convenience, suit to use in t
