摘要
设计了一种立式穿孔机上轧辊平衡装置液压回路。此回路能够实现上轧辊平衡装置纵向锁紧,辊距调整时向上调整跟随、向下调整时安全溢流,检修以及换辊时的慢速卸荷以及快速提升工艺动作。同时,高压锁紧回路可解决因平衡装置滑道磨损而无法完全向上锁紧的问题。
A hydraulic circuit of roller balancing device on vertical punch is designed.This circuit can realize longitudinal locking of upper roller balance device,safe overflow during upward adjustment,slow unloading and rapid lifting process during maintenance and roll change.Meanwhile,the high pressure locking circuit can solve the problem of completely locking due to the wear of the balance slide.
