Filed: 1969-05-22
Abstract: 1276132 Sheet metal feeds C BEHRENS AG 22 May 1969 [12 June 1968] 26102/69 Heading B3W A device for clamping a workpiece to a transverse carriage of the co-ordinate table of a turret punch comprises a clamp which yields if an obstacle is encountered and in so doing actuates an electric switch to cut off the drive to the punch and/or to the co-ordinate table. As shown, Fig. 1b, a clamp lever 4 pivoted at 5 is movable between positions I and II in which it respectively clamps and does not clamp a workpiece 16 to a support 1 by an hydraulic cylinder arrangement 6, 7. The support 1 is pivoted at 3 to a holder 2, mounted on the carriage 20 and maintained by springs 12 in a position in which a bolt 13 on the support bears on a surface 14 on the holder 2 and causes a bolt 8 secured to the holder 2 to remain in contact with a switch 9 controlling actuation of the punch (not shown). If in feeding the workpiece to a die 15 of the punch the clamp member 1<SP>1</SP> abuts, e.g., the die or a broken punch, the support will pivot about the bearing 3 against springs 12 and open the switch 9 to cut off drive to the punch. In another embodiment, Fig. 3, one or more hydraulically operated clamps 22 are mounted on a support 26 which is pivotable, about bolts 35, relative to a holder 29 itself adjustably mounted on a carriage 40 by screws 30. If the clamp encounters the die, for example, the support 26 pivots against the action of springs 33. The support can also move linearly, if the clamp encounters a broken punch for instance, annular seats 31 sliding bodily under core plates 32. Either movement opens switch 34 and cuts off the drive to the coordinate table. A further embodiment (Figs. 7 and 8, not shown) has a clamp, similar to that of Fig. 1b, carried by a holder, which is slidably mounted on the carriage in similar fashion to the device of Fig. 3, and so can cut off the drive to the punch and/or the co-ordinate table. The table may be manually or mechanically operated or controlled according to a pre-set programme.
