Abstract
A machine for producing points on the pilot end of a rotary fastener, the machine comprising a rotating dial for supporting an array of blank fasteners above a pair of dies. The blank fasteners are sequentially fed between the dies for pointing thereof. The dial is notched on its periphery to hold the blanks therein. The fasteners are held in coaxial alignment with the pinch point of the dies, by a notched biased centering plate, permitting accurate pointing of the fastener along the axis thereof.
Claims11
A pinch pointing machine for pinch pointing a point on screw blanks, said machine comprising:
- a pair of dies for pinch pointing, by a pinching operation, screw blanks therebetween;
- means for supporting successive screw blanks between said pair of dies;
- and
- alignment means for accurately securing both tangentially and radially each successive screw blank between said dies during the pinching of each of said blanks to permit their longitudinal axis to be properly aligned with said dies, whereupon said axis and the point on said screw blank are coaxial, said alignment means including a pivotable member with a screw blank locating portion thereon to help control the tangential and radial orientation of said screw blank between said dies.
