T形垫片冲压成型工艺及模具设计【冲孔、落料复合模】
摘要：本设计的题目为垫片冲压成形工艺及模具设计的设计,体现了薄板类冲裁零件的要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了本人冲压模设计的基础知识，为设计更复杂的冲压模具做好了铺垫和吸取更深刻的经验。
本设计运用冲压成形工艺及模具设计的基础知识，首先分析了冲裁件的冲压工艺性，为确定冲裁工艺方案做好了准备；然后计算冲裁力和模具刃口尺寸，便于选取压力机及确定工作零件的尺寸和结构；最后分析了制件的特征，确定模具的设计参数、设计要点及推件装置的选龋
本冲裁件上孔为非规则形状的孔,为了便于冲孔凸模的加工，所以在设计时把冲孔凸模设计成直通式,然后,将其铆接在凸模固定板上。此外,该制件的尺寸较大,为保证凹模的加工精度,在设计时应将其设计成凹模组件。为了方便制件的取出，本副模具采用倒装结构形式,同时,为了简化模具结构采用弹性推件装置。

Gasket stamping forming process and die design
Abstract：The designwas entitled Tension pulley die stamping design the basis of design, reflects the thin parts like punching the request, the contents and direction of a certain design significance. Parts of the mold through the design, has further strengthened my stamping die design of the basic knowledge for the design of more complex stamping die to pave theway and the lessons more profound experience.
The use of the design process and die stamping forming the basis of design knowledge and analysis of the first blanking of the stamping process, to determine blanking of the programme prepared for and then calculating punching power and size Die Cutting Edge, For selected press and determine the size and structure of parts of the last parts of the characteristics of the design parameters established mold, design features and pushing the select pieces of equipment.
Blanking of the rules on the shape of the non-hole hole, in order to facilitate the processing punch punching, punching in the design of the punch designed as a straight-through processing, and then, riveting in its punch fixed board. In addition, the larger the size of the parts, to ensure the accuracy of processing die, the design should be designed to die components. To facilitate the removal of parts, the Vice-use flip-die structure, at the same time, in order to simplify the structure adopt a flexible mold push pieces of equipment.
Keywords：stamping die, flip-composite, die components, flexible pieces of pushing
