一、结构在60吨冲床的曲轴端部离合器上,装上一个棘轮。棘轮的棘爪固定在床身侧面,由一个8公斤的牵引电磁铁带动。电磁铁在机床工作时是吸合的,棘轮套在离合器体上与曲轴和大飞轮一同旋转。一旦操作出现危险时,通过光电线路产生动作,电磁铁断电释放棘爪,在弹簧力的作用下,迅速推动棘轮,离合器停转,滑块停止运动。结构详见图1。 First, the structure 60 tons of crankshaft end of the clutch, fitted with a ratchet. Ratchet pawl fixed on the side of the bed, driven by an 8 kg traction magnet. Electromagnet in the work of the machine is sucked, ratchet sleeve clutch body with the crankshaft and flywheel together with the rotation. Once the operation is dangerous, through the optoelectronic circuit action, the electromagnet power release pawl, under the action of the spring force, quickly push the ratchet, the clutch stops, the slider stops moving. Structure shown in Figure 1.
