一、概述我厂生产的电机,其筒形外罩的圆周上均布着各式通风孔,有百叶窗式的、椭圆孔式的、或其他形状的(见图1)。过去,圆周通风孔的冲制多采用手工分度的冲孔模,效率低、工人劳动强度大。能否利用冲床的往返运动来完成自动分度呢了为此,从一九六五年起我们着手设计这种圆周冲孔自动分度模具,经过这些年来的不断实践、摸索,现已基本掌握了自动分度原理和模具设计中的有关计算问题。生产实践证明,这种自动分度模具结构简单
First, an overview of our factory production of motor, the cylindrical cover of the circumference are all kinds of vents, louver type, elliptical hole, or other shapes (see Figure 1). In the past, the use of circular punching punching manually indexing punching die, low efficiency, labor-intensive workers. Can use the punch reciprocating motion to complete the automatic indexing it For this reason, we started from 1965 to design such circular punching automatic indexing mold, after years of continuous practice, exploration, is now a basic grasp Automatic indexing principle and mold design in the calculation of the problem. Production practice has proved that this automatic indexing mold structure is simple
