(模具设计与制造.doc

摘 要 本设计为落料拉深复合模及典型工作零件的工艺分析。全文将设计思路作为一条主线贯穿始终，所采用的设计思路为：取得必要的资料对冲裁零件进行多方面的认识、分析，其中最重要的是对其进行工艺方面的分析。作好以上的工作后，设计进入了最为核心、最为重要的一步，即进行必要的工艺计算和确定模具主要工作零件的结构型式、相关尺寸。有了整个设计的核心灵魂后，然后对模具的其它组成零件完成设计，从而完善整个模具。综合上述的分析、计算、总体设计后，选好冲压设备，画好模具总装配图和各非标准零件图。整个设计思路是成一条脉络展现的。 关键词： 冲孔；落料；复合模；工艺分析；模具；拉深 ABSTRACT Compound die Blanking Drawing is an efficient and precise provision of normal stamp die. For the part can not finished in only one stamp working procedure，it is better machining on the compound die according to the technical demands of the part. In the thesis, designed a compound mold used to machining the half-finished clutch shell. This set of mold suits in the clutch shell punch central hole, stamp bottom convex shape, and shave fringe, after that still had several processing working procedures. When carries on the design of this compound mold, the main question is to confirm the way of stamp the bottom convex figuration. Because it is have to guarantee the fore working procedure’s approximate shape precise, uses partial-undulate stamp in here to processing the bottom bulge. Therefore, the key role to succeed of the partial-undulate stamp is to define reasonable blank holding force. At the same time, when stamped conical convex bulge, the design of convex-concave die is also important. In order to the standardized design, has selected the standard part as far as possible. Such as die frame, die bed plates, press machine and so on. Finally, set down the machining technical procedure of sleeve, a major mold component. The design in the thesis has some referenced value for analogical calendaring molding design.
