刚性离合器结构的压力机,其单次行程控制方式目前基本上有两种.一种是机械控制,曲轴上的凸轮(或撞块)与操纵器上的弯棒配合动作,凸轮与弯棒撞击一次,通过操纵器的动作离合器就接合或脱开一次.这种力式用于小吨位的压力机上居多.另一种是机械电气联合控制,即取消弯棒,使曲轴上的碰头与行程开关相碰一次,牵引电磁铁就通电一次,从而使操纵器动作一次,达到压力机单次行程的目的.
Rigid clutch structure of the press, the single stroke control at present there are basically two kinds of one is the mechanical control, crankshaft cam (or block) with the manipulator on the bending rod with the action of the cam and the curved rod impact Once, through the manipulator action clutch engaged or disengaged once.This force is used for small tonnage presses on the majority.Another is the mechanical and electrical joint control, that is, to eliminate bending rod, the crankshaft on the head and the trip switch Collision time, electromagnet traction on the power once, so that the manipulator action once to reach the purpose of the press a single trip.
