Abstract

884,079. Making corrugated tubing. YOWELL J. W., and MINER D. B. March 10, 1958, No. 7691/58. Classes 99(1) and 99(2) [Also in Group XXII] Corrugated tubing e.g. of metal, comprises a resilient tubular body made from a single piece of tubing having annularly extending corrugations formed by inner cylindrical wall portions 23, Fig. 7, and outer annular wall portions 42 having a substantially part-circular axial crosssection which normally extends through an arc materially greater than 180 degrees and is free from reverse curvatures. Tubing 10, Fig. 2, having hydroformed corrugations made as disclosed in U.S.A. Specification 1,946,472, is placed in a formed jig 16 composed of separable sections 17 secured together by bolts. An eccentricallymounted mandrel is rotated about its axis so as to flatten the portions 15 against the cylindrical portions 21. In another method an uncorrugated tube is subjected to internal fluid pressure to flatten the portions 23, Fig. 4, against the bores of a series of axially displaceable rings 26. Tubing formed by either method is then clamped at each end in a device 28 to enable the tube to be lengthened by turning the handle 37, which by means of the screw threaded rod 36 and mating bush 39, moves the end plate 30 away from the end plate 39. With the tubing cross-section shaped as shown at 41, hydraulic pressure is introduced into the tube through a conduit 33 to cause the portions 12, 13 and 14 to be ballooned out whilst the tube is shortened by rotation of the handle 37. Long lengths of tubing may be supported internally by a tube 40a. The corrugations of a conventional closed end bellows 44, Fig. 8, are reworked by internal press sure, as in Fig. 5, in a device 43 by clamping the bellows flange between a plug 47 and a seat 48. Rotation of a cam 51 provides positive control over the length of the bellows by simultaneous movement of a rod 50 and a platform 52. Specification 778,689 also is referred to.
