Abstract

1,192,769. Punching. KINGSLAND ENG. CO. Ltd. 30 July, 1968 [18 Aug., 1967], No. 38064/67. Heading B3W. A machine for punching holes simultaneously in two flanges of a beam, girder &c., e.g. of I or T section, comprises a holder for a plurality of simultaneously-operable punches and a bolster having a cavity therein, or being formed in two spaced parts to accommodate the web and other flanges, if any, of the beam &c. during punching. As shown, a punch (14) and a punch (16), Fig. 2 (not shown), are mounted in a ram (not shown) housed in a head 12 of a C-frame and dies 17 are mounted in a bolster comprising twin heads 18, 19 and sub-bases 22, 23 to which the heads are bolted at 20, 21 for adjustment towards and away from each other. The sub-bases are bolted to a baseplate 26 at 24, 25 and are also adjustable towards and away from each other. Screw jacks 27 are provided on the heads 18, 19 for centring a beam 15. A stripper frame 29 secured to the head 12 at 30 carries stripper plates 31 each rigidly attached to threaded bolts 35 adjustable relative to the frame by means of nuts 33, 34. The ram is actuated by a treadle (not shown).
