Abstract

950,807. Punching. C. BEHRENS A.G. Aug. 8, 1962 [Aug. 30, 1961], No. 30320/62. Heading B3W. A turret plate for a multiple punch press has a hold-down and stripper plate which moves in advance of the punch and which holds the material until the punch has been withdrawn. An upper turret plate 1 and a lower turret plate 2 are mounted on spindles 3 and 4 in a frame 5. Tool-holders 6 are mounted in the plate and moved in turn into engagement with a ram 7. A hold-down and stripper plate 8 is mounted on a shaft 9 which is free to move axially in the spindle 3. Within the shaft 9 is a resilient member 11 and a tappet 27 which is acted on by a cam 15 on the driving shaft 25. Operation.-The movement of the plate 8 precedes the movement of the tool-holders 6 so that the hold-down is in contact with the workmaterial before the punches operate. During this movement the resilient member 11 is loaded beyond its normal condition so that it remains in contact with the work as the punch is withdrawn until the latter is clear of the work. The hold-down is finally lifted by springs 12. In a modification the hold-down is mounted on a rigid shaft 9 which has a camfollower roller 32 at its upper end. The shaft is released for downward movement by the longitudinal movement of a rod 20 which has a cam 21 formed thereon, and which operates the tool-holder 6 through a toggle linkage 31. The hold-down and stripping pressure in this instance is provided by resilient members 41 situated between the turret plate 1 and the hold-down plate 8.
