Schneidwerkzeugbaueinheit in Schraubenfederwickelmaschinen

摘要

The present invention relates to a cutting tool assembly which can cut spring wires in either a vertical or a progress tilt direction in coil spring winding machines. This assembly uses a cam seat and a cam center guide seat for the cutting in a vertical direction. To do the cutting in a progressive tilt direction, the cam center guide seat is dismantled and the slide in the cam seat is fixed by screws. The cutting point can also be adjusted for the manufacture of special springs. This assembly provides a cheaper and an easy way for switching the cutting direction.
