METHOD OF USING A PIERCE NUT INSERTION TOOL

摘要

A pierce nut insertion tool is provided. In another aspect, a pierce nut feeding mechanism has a mechanically independent driver actuator from that of a punch. A further aspect of the present tool employs a member, moveable with a punch, that retains a pierce nut prior to fastening of the nut to a workpiece. An additional aspect uses a fluid actuated nut feeder including a piston.

主权项

1. A method of using a pierce nut insertion tool comprising:
(a) applying fluid pressure to advance a piston toward a punch axis; (b) feeding pierce nuts along a path, located on an opposite side of the piston from a moveable press platten, in response to step (a); (c) moving the nut path and piston away from the platten by an actuator to assist in the pierce nut feeding; (d) allowing one of the nuts to be advanced and aligned with the punch axis; (e) moving the nut path and piston toward the platten, after step (d); and (f) creating a hole in a workpiece and clinching the pierce nut to the workpiece by the punch pushing the pierce nut against the workpiece.
