筒形传感器外壳冲压模具设计
摘要
冲压加工是现代机械制造业中先进高效的加工方法之一。它是利用安装在压力机上的模具，在常温或加热的条件下对板材施加压力使其变形和分解，从而获得一定形状、尺寸的零件加工方法。采用普通的冲压的模具生产较率低，且费用较高，经估算占冲压件总成本的30%～40%，甚至更高一些。根据工件特点选择采用级进模冲压生产以提高生产效率、降低生产成本。本次设计采用级进模冲压生产。本文对采用级进模冲压生产弯角的分析，计算以及具体方案做了介绍。

Cylindrical Sensor Housing Stamping Die Design
Abstract
The stamping is one of the modern machinery manufacturing state-of-the-art and efficient processing methods. It is installed in the press mold, and applying pressure to deform and decomposition of the plate under the conditions of room temperature or heated to obtain a certain shape, the size of the parts processing method. The ordinary stamping mold production is relatively low, and the cost is higher, the estimate accounted for 30% to 40% of the total cost of stamping parts, and even higher. According to the work piece characteristics of progressive die stamping production in order to improve production efficiency, reduce production costs. The design uses a progressive die stamping production. Analysis of progressive die stamping corner, computing, and specific programs is introduced.
