筒形傳感器外殼沖壓模具設(shè)計

摘要

沖壓加工是現(xiàn)代機械制造業(yè)中先進高效的加工方法之一。它是利用安裝在壓力機上的模具，在常溫或加熱的條件下對板材施加壓力使其變形和分解，從而獲得一定形狀、尺寸的零件加工方法。采用普通的沖壓的模具生產(chǎn)較率低，且費用較高，經(jīng)估算占沖壓件總成本的30%～40%，甚至更高一些。根據(jù)工件特點選擇采用級進模沖壓生產(chǎn)以提高生產(chǎn)效率、降低生產(chǎn)成本。本次設(shè)計采用級進模沖壓生產(chǎn)。本文對采用級進模沖壓生產(chǎn)彎角的分析，計算以及具體方案做了介紹。

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.

Key Words: Corners; Progressive die; Stamping
