空调垫片正装下顶出落料模设计

摘要

冲压模具作为制造产品（或半产品）的一种工具，其作用是完成某种工艺。模具设计必须满足工艺要求，最终满足产品的形状、尺寸和精度的要求。因此冲压设计师必须掌握冲压工艺，包括冲压工艺的分类、各种工艺计算、工艺制订等基础知识，而后才可以选择模具的类型，进行模具设计，使模具的类型表面质量、尺寸精度结构及尺寸等满足工艺及产品的要求。
冷冲压工艺大致分两类：分离工序和成型工序。分离工序的目的是在冲压过程中将冲压件与板料按一定的轮廓线进行分离：分离工序又可分为落料、冲孔和剪切等。成型工序的目的是使冲压毛胚在不破坏其完整性的条件下产生塑性变形，并转化成产品所需要的形状：成形工序又分为弯曲、拉深、翻边、翻孔、胀形、扩孔等。
冷冲压模具是冲压生产的主要工艺设备。冲压件的表面质量、尺寸精度、生产率以及经济效益等，与模具结构及设计是否合理关系极大。

Just pack a singlework preface to fall to anticipate the mold

Abstract

Hurtle a kind of tool of press the molding tool conduct and actions manufacturing product(or the half product),its function is to complete a certain craft.Therefore hurtling to press designer must control to hurtle to press the craft,the classification,various craft calculation,craft that includes to hurtle to press the craft establishes etc.the foundation knowledge,just can choose the type of the molding tool and then,carryon the molding tool design,make the type,structure and size etc.of the molding tool satisfythe request of the craft and product.
Cold hurtle to press the craft to divide mostlytwo type: Separate thework preface and model thework preface.Purpose that separates thework preface is at hurtle to ran over the distance lieutenant general to hurtle to press the piece and planks to anticipate to press certain outline line to carryon the separation: Separating thework preface can is divided in to fall to anticipate again,blunt bore and shear to slice etc..The purpose that models thework preface is to make hurtle to press the hair,the creation transforms under the condition of not break its integrity,and convert the shape that product need: Take shape thework preface and is divided into the flection and pull deep,turn over the side,turn over the bore,bulge form and expand the bore,etc..Cold hurtle to press the molding tool is main craft equipments that hurtles to press to produce.Hurtle the surface quantity,size accuracy,rate of production and the economyperformance etc.of press the piece,with the molding tool structure and designswhether the reasonable relation is biggest.
Keyword: Fall to anticipate,plastic deformation,the craft calculation,craft establish,surface quantity,size accuracy
