Binding machine

摘要

A binding machine includes a body, an actuator coupled with the body, and a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator. The punch mechanism includes a plate including a plurality of punch pins. The punch pins are configured to punch through the stack of sheets during a punch stroke. A shaft is coupled with the actuator such that movement of the actuator causes rotation of the shaft. At least one cam is mounted on the shaft for rotation therewith. The cam is coupled with the plate to drive the plate in a punching direction. The cam includes a cam profile that dictates displacement of the plate in the punching direction relative to rotation of the shaft.

1. A binding machine comprising:
a body; an actuator coupled with the body; a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator, the punch mechanism including a plate including a plurality of punch pins configured to punch through the stack of sheets during a punch stroke, the plate having an edge; a shaft coupled with the actuator such that movement of the actuator causes rotation of the shaft; at least one cam mounted on the shaft for rotation therewith, the cam coupled with the plate adjacent the edge to drive the plate in a punching direction, the cam including a cam profile that dictates displacement of the plate in the punching direction relative to rotation of the shaft; and a non-metallic material positioned along a portion of the edge between the cam and the plate such that rotation of the shaft causes the cam profile to directly contact and slide against the non-metallic material to displace the plate in the punching direction.
