在实现冲床单机自动化的过程中,对拉伸、压弯模压出的立体工件如何快速取出是个问题。对于这类工件,我们设计了一套往复式凸轮机构。当工件从模具脱出之后,以高速横向将它打出。经使用证明效果很好。凸轮机构的关键部件是斜铁4与在它外边的叉型压块5。当上模向下运动时,打料杠杆13顶住叉型压块底部,使它向上滑动,弹簧3被压缩,此时打料杠杆被斜铁5的斜面排挤,匀速向反时针方向转动。转动到φ_1角度后打料杠杆滑过叉型压块圆角以外,叉型压块在
In the process of realizing single press automation of punch press, it is a problem how to quickly remove the three-dimensional workpieces of drawing, bending and bending. For this type of workpiece, we designed a reciprocating cam mechanism. When the workpiece is removed from the mold, it is shot laterally at high speed. The use of proven good results. The key components of the cam mechanism are the chamfer 4 and the fork clamp 5 outside it. When the upper die moves downwards, the material feeding lever 13 can press against the bottom of the fork-type pressing piece to make it slide upwards and the spring 3 is compressed. At this moment, the material feeding lever is squeezed by the inclined surface of the inclined iron 5 and rotates in a counterclockwise direction at a uniform speed. Rotation to φ_1 angle after playing the material lever lever over the fork outside the fillet, the fork-type briquetting in
