Progressive die design of hoop parts

The invention discloses a progressive die design of hoop parts. The progressive die design comprises a male die, a female die, a stripper plate and a strip stock layout of the whole progressive die. All the parts are combined together in an assembling mode and are fixed through pressing screws and positioning pins. The hoop parts have the characteristics of precision and thinness, have very high requirements on the material, the machining mode and the heat treatment process of workpieces, the error accumulation caused by multiple times of machining of a single die can be overcome by adopting the progressive die for machining, the workload of production workers is simplified, the production efficiency of the precise and fine hoop parts is improved, and large-scale batch production of the hoop parts is realized. 本发明公开了一种卡箍零件级进模具设计，包括整个级进模具的凸模、凹模、卸料板和条料排样。所有的零件采用装配的方式组合在一起，通过压紧螺丝和定位销固定。卡箍零件具有精、薄的特点，对工件的材料、加工方式、热处理工艺都有很高的要求，采用级进模来进行加工可以克服单一模具多次加工所造成的误差的累计，简化了生产人员的工作量，提高了精密细小的卡箍零件的生产效率，实现了卡箍零件的大规模的批量生产。
