众所周知,吨位在100tf 以下的压力机一般采用刚性离合器。但是由于该类离合器只能实现单次和连续行程,不能实现寸动行程和急刹车,这对于模具的安装调整很不方便,也是经常发生断指事故的原因,其发展受到了一定的限制。针对这一问题,我们先后研制成功滑环式和拔杆式离合器,并在此基础上,经过改进,发展成为压杆式和顶杆式离合器。现将其工作原理和设计要点分述如下。 As we all know, tonnage presses below 100tf commonly used rigid clutch. However, due to the type of clutch can only achieve a single and continuous travel, can not achieve inching stroke and brakes, which is very inconvenient for the installation and adjustment of the mold, but also the frequent occurrence of finger breakage, its development has been subject to certain restrictions. In response to this problem, we have successfully developed a slip ring and pull rod clutch, and on this basis, improved to become the pressure rod and jack rod clutch. Now its working principle and design points are as follows.
