上连接板模具设计
摘 要
本设计题目为弯曲模设计,体现了弯曲模的设计要求、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弯曲模设计的基础知识,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。成型原理可划分为两个阶段:首先,凸模与凹模共同作用成型U形件;凸模继续下行,最后成型制件,这种机构动作灵活可靠,设计方便,非常适合在本副模具中使用。

Abstract
The requirement ,content and direction of the design of the bending dies parts are embodied on this bending dies design. The designer’s foundation knowledge of the bending dies design is reinforced and is able to design more complex injection mould through the design.
Through the foundation knowledge, firstly, the composion and the perfourmance of the flat sheet is analyzed to choose the type of the mould. Secondly, the volume of the bend is estimated to choose the press molding machine and to detemine the type press machine and tonnage of press. Lastly the character of the part is analyzed to determine the mould design parameter and design point and choose the ejection assembly.
Especially fit for volume produce and hight precision produce.Moulding of the part is like this :Fist,behing punch and die’s together operation, the part is form to the fast bending ; punch is going down, swing block is flogged to work, and the second bending is begin. At last, the part is form to part. This device’s action credibly and design conveniencly. So, it is adapted to be used on this mould extraordinarily.
