本文分析了钟表元件二轮压簧的成型工艺特点，其中包括利用对工件展开图的尺寸计算、工件的工艺分析、冲裁力的计算、模具设计的难点，确定了级进模的排样方案和模具总体结构，而且校核了凸、凹模的强度。

The shaping course of Fine blanking is very complex. Material forms a local plastic cutting area between punch and bottom die, and brings violent plastic flow under the effect of press stress. The grad of stress and strain is great, and it is an unstable transmutation process that came through an elastic distortion, plastic distortion and cut rupture.

精冲成形过程非常复杂，材料在狭窄的凸、凹模间隙附近形成了局部塑性剪切带，在压应力的作用下产生强烈的塑性流动，应力应变梯度很大，是一个经历弹性变形、塑性变形和剪切断裂的非稳态大变形过程。

A kind of gas-and-liquid springy pressure setting was designed for fine blanking die holder.

磨损后也不用拆卸模架，更换零件，这样，保证了模架高寿命的特点。

But in practice, due to the condition and tradition, for both the blanking and punching, the usual way is to produce punch first and then the die plate, or in the opposite way, so the conversion between them is needed.

但在实际生产中，由于条件和习惯的原因，部分工厂采用不分落料、冲孔，均是先制造凸模，再配制凹模，或者反之，这样就需要进行换算。

Based on gaining high productivity and the high percentage of material consumption,We made the choice of using two dies to fulfill the design: one progressive die to execute punching, drawing and blanking.we use the second bending die with a wedge to get the two bends.

本设计以提高生产率及材料利用率为出发点，采用两套模具进行该启瓶器的设计：第一套级进模完成冲孔、拉深和落料；第二套模具为楔块式弯曲模，用来完成两次弯曲成形。
