加强板零件冲压工艺与模具设计.doc

摘要
冲压模具在实际工业生产中应用广泛。在传统的工业生产中,工人生产的劳动强度大、劳动量大,严重的影响了生产效率的提高。随着当今科技的发展,工业生产中模具的使用,已越来越引起人们的重视,而被大量应用到工业生产中来。冲压模也投入到实际的生产中来,冲压模可以大大提高生产效率,减轻工人负担,具有重要的技术进步意义和经济价值。
冲压是冲压加工的简称,是通过压力机(俗称冲床)和安装在压力机上的模具,对模具里的材料(一般是金属和非金属板材)施力,是材料在模具里变形,从而获得形状、尺寸符合要求的零件的生产技术。冲压加工通常是在常温下进行,不需要对材料进行加热,所以又叫冷冲压。
本文介绍的模具实例结构简单实用,使用方便可靠,对类似工件的中批量生产具有一定的参考作用。

Doubling ponents ramming craft and mold design

ABSTRACT
Through carries on the technological to the doubling plate work piece analysis, knew this work piece needs two working procedures the processings, namely falls the material punch holes two set of plan contrasts, decided designs set pound molds, namely falls the material punch holes true thing superposable die; Another set is a bending die.
Falls the material punch holes superposable die the convex-concave mold, the punch holes raised mold, falls the material concave mold the shape all is by the work piece determination, is similar with the work piece shape, the external dimensions all are pass through the putation its blanking force is not too big, but also considered the stress is even, therefore selects the middle guide pillar pould frame, and selects the corresponding guide pillar, the guide in order to lengthen the die bed life, therefore has selected the appropriate about backing convex-concave mold must have to have the accurate position, can guarantee the work piece can form precisely, therefore the reference standard also the basis actual situation have selected the convex-concave mold dead plate, The punch holes raised mold dead plate, guarantees well the fixed convex-concave mold and the punch holes raised order to guarantee the work piece to be smooth the mold and convenience waste material abscission, utilized the elasticity to go against an equipment, the rigidity pushes an equipment and the elastic dumping device.
But the bending die is very simple, only used the elasticity to go
