Abstract
687,555. Punching. WALES-STRIPPIT CORPORATION. Aug. 31, 1951 [Jan. 26, 1951], No. 20568/51. Class 83 (iv). In a punch and die holder for a punching machine the punch, punch guide and stripper assembly are supported by a lifting spring independent of the assembly. A punch P adjustable by a nut 52 is withdrawn in a stripper 50 guiding the punch by springs 58 limited in action by a stop-pin 60. The stripper 50 is guided in a bush 30 in a C-frame 20 housing a die D and adjustably secured to a slotted bed by bolts 44. To support the punch assembly relatively to the die an arm 70 urged by a spring 85 is controlled by a screw 80 engaging the frame. By adjustment of the screw 80 the lever 70 varies the position of the punch and stripper relatively to the die. When the lever 70 is depressed by the screw 80 the punch assembly falls by gravity to facilitate alignment of a centre point on the punch with indentations in the workpiece. In a modification, Fig. 11, not shown, the die can be removed from the bottom of the frame. The work may be positioned by gauging stops, Fig. 9, not shown, or by conical centre on the punch. By adjusting the nut 52 engaging a screwed end of the punch the compression of the springs 58 may be varied.
