Abstract
1,122,286. Sub-press mechanism. MINNIE PUNCH & DIE CO. Inc. 17 Aug., 1965 [2 Nov., 1964; 16 Nov., 1964], No. 35304/65. Heading B3W. A sub-set comprises a magnesium punch. plate 4, a die-plate 6 and guide pins 8. The pins 8 are retained in bushes 12 in the punchplate 4 by circlips 10 and slide in bushes 14 in the die-plate 6. The plates are urged apart by springs 18 and the movement is limited by circlips 16. By this construction the guide pins are made easily removable. The tool shown is a combined blanking and piercing set and includes a blanking die 32 attached to the punch-plate and a blanking punch 56 attached to the dieplate 6. An ejector plate 34 in the blanking die 32 is acted on by disc spring assemblies 29 through pins 36. The movement of the ejector plate is limited by studs (49), Fig. 6 (not shown). The spring assemblies 29 are contained in housings 40 and can be removed by loosening a screw 52 which locks a clamping plate 50. A stripper plate 37 surrounds the blanking punch 56 and is acted on by disc spring assemblies contained in cylinders 28 which also support the die-plate. The springs act on pins 35 which pass through the die-plate. Above each pin 35 a head 39 is positioned on the upper face of the stripper 37 and secured to the pin by a screw 41, Fig. 8. The thickness of the head is at least twice the thickness of the work material 54, so that as the punch-plate 4 moves upward the component part is ejected from the blanking die and then the webbing is stripped from the punch. In a modification. Figs. 10 and 11 (not shown), the ejector plate (127) which corresponds to the ejector-plate 27 of Fig. 2, is held in position in the blanking die by pins (128) which pass through a punch-plate (115) and a backing-plate (124). The pins are acted on by a further plate (132) which is loaded by disc springs (138). There are projecting bosses (139) on the plate (132) which align the disc springs and which enter apertures in a striker plate (131). In both the embodiments described the ejector actuating assembly can be removed from the die set for use in a similar type of set.
