ABSTRACT:
A compression head for a hydraulic compression tool comprises a fixed die and movable dies, the fixed die being mounted on a stationary head attached to a tool body and the movable dies being positioned within the stationary head and actuated by a piston of a pump mechanism equipped in the tool body. The piston is attached at its front end to a guide plate having a center support and two side supports. The guide plate is provided at both front and reverse sides with guide grooves. Each of the movable dies rests on the upper surface of each side support through a roller means, while it is interposed between two guide plates slidably engaging with said guide grooves of each side support. Further, each of the movable dies is supported against the center support by a return spring, which is received at one end by an insertion hole of each movable die and at the other end by a cutout on the center support.
