Abstract

1312454 Punching ROHRTECHNIK OSTHOFF GmbH & CO KG 16 April 1970 [6 Aug 1969] 39419/69 Addition to 1162355 Heading B3W A device for punching holes in a tube comprises a punch, a mandrel for insertion in the tube having a solid die portion with a die aperture adjacent one end for co-operation with the punch and being supported at the other end, means for pressing the die portion against an inside face of the tube, an open-ended hollow guide surrounding the die portion of the mandrel and having an aperture aligned with the die aperture and means for pressing an outer face of the tube against an inner face of the guide. As shown, the mandrel 11 in the region of the die portion 11A is urged against the inner face 40 of the tube 20 and the tube is urged against the inner face of the wall 27 of the tube guide 16. The guide is mounted on a bed 17 and has a punch aperture 28 in the upper wall 24 and a die aperture 30 in the bottom wall 25 which is aligned with an aperture in the bed 17. The mandrel is supported at its end remote from the die portion on a fixed bed (14) by brackets (12), (13), Fig. 1 (not shown). The tube is supported on a roller bed and is fed on to the mandrel by a pair of feed rolls. The springs 33, 34 and 38 may be replaced by fluid pressure means.
