光电保护在装有摩擦离合器的压力机上应用比较成熟,因为摩擦离合器可以使滑块停止在任意位置上,若用在具有刚性离合器的压力机上则只能起到闭锁滑块启动的作用,即挡住光幕时滑块启动不了。一旦启动之后,光电保护就不能起保护作用了,此时,手伸进上、下模具之间就有发生冲手的危险,这是因为刚性离合器不能使滑块停止在任意位置上,只能使滑块停止在上死点。 D207C—A型光电保护装置是我厂生产的。为了使这种产品能够更好地用在刚性离合
Photoelectric protection in the friction clutch equipped with the press more mature, because the friction clutch can make the slider stop in any position, if used in the press with a rigid clutch can only play the role of blocking the slider to start, that block Light curtain can not start when the light curtain. Once activated, the photoelectric protection can not play a protective role, this time, the hand stretched into the upper and lower molds there is the danger of red hand, this is because the rigid clutch can not stop the slider in any position, only Stop the slider at top dead center. D207C-A-type photoelectric protection device is produced by our factory. In order to make this product can be better used in rigid clutch
