Abstract
Incorporated with a heading machine for cutting continuous wire stock into required lengths for subsequent heading operation, the shearing apparatus includes a movable shear element against which is clamped a wire length to be cut off and which is reciprocated with respect to a fixed shear element. For reciprocating the movable shear element, which is carried by a slide, there is provided an actuator lever having a pusher member operatively mounted on its free end. The pusher member pushes the slide via an abutment thereon during the forward or cutting stroke of the movable shear element and, during the return stroke, via an air cylinder secured to the slide and held under constant supply of pressurized air. Upon completion of the return stroke, the air cylinder retracts to permit the actuator lever to pivot through an additional angle, with the consequent creation of a space between pusher member and abutment, so that the actuator lever can be pivoted back unloaded through the additional angle before commencing the forward stroke of the movable shear element.
