摘要： A hydraulic puncher comprises a generally C-shaped frame member having a pair of opposed ends between which a workpiece is disposed, and a hydraulic actuator fixedly connected to one end of the frame member. Provided on one end of the frame member is a ram having a punch fixed to the front end of the ram and reciprocated by an actuator. The other end of the frame member supports a die cooperating with the punch via a removable die mount. The die mount has a groove open toward the interior of the C-shaped frame, for receiving a part of a workpiece.
