Abstract
801,628. Corrugating tubes; making bellows. INDUSTRIE-WERKE KARLSRUHE A.G. Nov. 17, 1955 [Nov. 25, 1954], No. 32906/55. Classes 83 (2) and 83 (4). A method of shaping a steel pipe into bellows includes rolling successive corrugations into the pipe from the outside while simultaneously exerting axial pressure on the pipe from both ends thereof. A pipe 6 to be corrugated is clamped on heads 2, 2a, journalled in carriages 27, 25, with annular members 7 positioned in previously formed corrugations 13, 14. To form the next corrugation 15 a motor 29 is switched on to rotate the head 2 and thus the pipe 6 and a burner 35 is ignited to heat the zone to be grooved. Holders 38, three in Fig. 2, two in Fig. 4, journalled in a carriage 23b, 23c and each carrying three rollers 10, 11, 12 of increasing diameter and decreasing width, are then rotated by motors 30, switched on by hand or automatically by a temperature-measuring device 36, so that the rollers in turn bear on the heated part of the tube to form the corrugation. A cam disc 32 on the shaft of a holder 38 switches on a motor 17 to rotate a threaded shaft 21 to move the carriages 25, 27 together to compress the tube 6 axially as the rollers bear thereon. The motors 17, 29 and 30 are switched off by the cam disc 32 and a motor 18 then switched on either automatically or by hand to rotate a screw 20 to move the carriage 23b, 23c to a position to form the next groove. In an alternative arrangement, Fig. 5, the corrugated end of the pipe is accommodated in a rotated drum 52 and the last corrugations formed engaged by pivoted gripper segments 50; adjacent corrugations may also be so engaged. In this embodiment two sets of shaping rollers one at each end of the pipe may be provided.
