我们在制造冲床自动送料机构时,遇到了送料杆的往复运动曲线不对称的问题,如果用凸轮来满足,机构较复杂。为此,我们设计了如图所示的斜板加衬板的装置,满足了要求,其工作原理如下: 滚轮1通过联接装置固定在冲床滑块上,作为原动件。斜板3、衬板4的厚度相等,都是滚轮长度的一半,斜板固定在送料杆5上,衬板用销安装在斜板上,并可绕销2转动。当冲床滑块下落时,滚轮沿斜板的斜面运动, We are in the manufacture of automatic punch feeding mechanism, the feed rod encountered reciprocating curve asymmetry problem, if the cam to meet, the mechanism is more complex. To this end, we designed the device as shown in the ramp board lining to meet the requirements, its working principle is as follows: Roller 1 through the coupling fixed to the punch slider, as the prime mover. Inclined plate 3, the thickness of the liner 4 are equal, are half the length of the wheel, the ramp plate is fixed on the feed rod 5, the liner pin mounted on the ramp, and can rotate around the pin 2. When the punch slide down, the wheel along the ramp ramp movement,
