锻压自动机的大部分机构是用凸轮传动的。凸轮轮廓的设计目前有两种方法,一是作图法,即反转法;一是计算法,即分析法。作图法是利用机构运动的相对原理,假设凸轮不动,从动杆向相反方向运动。在不同的运动位置上,画出从动杆行程(或转角)的大小,把这些行程的端点连 Most of the mechanisms for forging robots are cam-driven. There are two methods for the design of the cam profile. One is the mapping method, that is, the inversion method. The other is the calculation method, that is, the analysis method. Drawing method is to use the relative movement of the mechanism, assuming that the cam does not move, the driven rod to the opposite direction of movement. In different sports position, draw the follower lever stroke (or corner) size, the end of these trips even
