Abstract

1389214 Stamping NATIONAL RESEARCH DEVELOPMENT CORP 28 March 1972 [2 April 1971] 8513/71 Heading B3Q Apparatus for forming work into a diecavity comprises a blank holder, a ring surrounding and holding the die, and means attached to the ring for vibrating the ring and die in a radial resonant mode. A ring vibrator, Fig. 1, may be used which is driven by vibration units 6. A further form of ring vibrator (14), Fig. 2 (not shown), has radial slits (17), and vibration units (19). This form of vibrator 41, Fig. 4, is used as a holder for a die 40 and is supported on a ring 62 and on a central sleeve 68 which engages screwthreads in the vibrator 41 and has a collar 74 engaging a groove in the vibrator. Slits 77 are formed in the upper end of the sleeve and a base flange 69 is clamped to a ring 70 fixed to a support 64. A punch 42 for the die 40 is surrounded by a hold-down piston 53 in a cylinder 45. In another form using a vibrator similar to that in Fig. 1, the vibrators (26), Fig. 4 (not shown), vibrate the die-holder (23) or both the die-holder and the hold-down (30) in antiphase.
