模制件

The purpose of this task is designing a multi-position concessive mould for normal rotating frame, through analysis of the part' technology performance and punching process designing, finished the position designing, and then to design the mould plunger, mould cavity, material leading and dumping device and the distance design.

本设计为普通转动插件设计一副多工位连续模，通过对其制件进行工艺性分析和冲压工艺设计，然后完成排样设计，进而对凸模、凹模、导料、卸料装置、定距等进行设计。

Taking the drawing die for the wheel spoke as an example, a method by adopting the rigid blank_holding ring after refining treatment, and by controlling the clearance between the blank_holding ring and the matrix surface and reducing the curvature radium of the matrix mouth was introduced.

以车轮轮辐拉伸模为例，介绍采用调质处理的刚性压边圈，并通过控制压边圈与凹模平面的间隙和减小凹模口圆角半径的方法，能够实现在普通压力机上直接拉伸，使制件质量稳定、操作简便，并降低了生产成本，提高了材料的利用率。

Indetail narrated had considered the workpiece the characteristic, hasused mold two cavities; Considered takes shape the after outwardappearance and so on, uses a type gate; Considered productionprocessing process convenience, in mold actual utilization rationaland so on, uses grading, the throwout lever unifies two time goesagainst the structure plan.

详细地叙述了考虑制件的特点，采用了一模两腔；考虑到成型后的外观等，采用点式浇口；考虑到生产加工过程的便利，模具的实际运用中合理性等，采用推板、推杆结合的二次顶出结构方案。

Cracks,goffers and other defects often occurred in large work-piece products by expansion mould due to the big tensile deformation.

在生产中大型制件胀形模，由于材料拉伸变形较大，往往导致制件开裂、起皱等问题。

The riveting technique for an electric contact was improved,and the processing technology for the bridge joint subassembly and the feed in scheme for the electric contact were determined.

通过对电触点铆接方法的工艺改进，制定了定位桥组件的生产工艺及电触点的送进方案，实现了电触点在精密多工位级进模内的自动送入及其与冲制件的装配、铆接。

In terms of defects of the traditional oblique wedge die with several side holes that had position degree at the same product,method of integration with rotating wheel and slant was adopted.

针对传统的斜楔模在同一制件上冲制有位置度要求的几个侧孔时的缺点，采用转动盘与斜面相结合的方式，在同一副模具上同时冲出有位置度要求的4个孔。
