Title: Improvements in tube bending machines
IPC: B21D11/08
Filed: 1954-09-29
Abstract: 761,200. Angular bending ; rolling annular bodies. WILMAN, S. Sept. 29, 1954, No. 28108/54. Class 83 (4). A machine for bending a tubular article through a cold-rolling operation by thinning out the wall of said tubular article in the region of its outer arc of bending includes roller means adapted to rotate inside the tube as it is fed in its longitudinal direction between supporting guide members. A tube 1 to be bent is inserted between stationary guide members 19, 20 over a mandrel 18 in which is rotatably mounted in bearings 17, a stub shaft 13 rotated, about an axis 6 offset from the tube axis 2, by a drive shaft 16. The stub shaft 13 has loosely mounted thereon a roller 3 rotatable about an axis 4 offset from the shaft axis of rotation 6 so that the roller is carried round in a circular path eccentric to the tube cross-section so as to roll, and thus thin, only one part, the lower, of the tube section, such thinning causing the bending of the tube. Loosening or tightening of the guides 19, 20 about the tube lessen or increase the circumferential extent of the rolling. The axis of rotation 6 of the stub shaft 13 is raised or lowered relative to the tube axis 2, to vary the depth and extent of the rolling, by means of oppositely rotated eccentrics 21, 22 interposed between the stub shaft bearings 17 and the mandrel 18. The eccentrics 21, 22 are secured to outer and inner sleeves 31, 32 respectively, surrounding the drive shaft 16 and formed at their rear ends with opposed bevel gears 33, 34 which are engaged by a bevel pinion 35 turned by a hand wheel, to effect the required adjustment. The axis 4 of the rolling wheel 3 is adjusted to or from the axis of rotation 6 of the stub shaft 13 to vary the depth of rolling by means of an eccentric 23 interposed between bearings 17 and the stub shaft 13. The eccentric 23 is secured to a sleeve 38 and normally rotates with the stub shaft 13 but is rotated relative thereto, to effect the adjustment, by means of a worm 50, rotated by a hand wheel, which engages an internallytoothed annulus 40 on which roll planet pinions 41 engaging a sun gear 42 on the sleeve 38. The pinions 41 are rigid with pinions 45 engaging a fixed annulus 43 and a sun gear 44 on the drive shaft 16. The tube 1 is fed longitudinally during rolling by a carriage 83 moved along horizontal racks 63, 64 (not shown), by gear means on the carriage rotated by a splined shaft 55. The bent tube is supported after leaving the rolling means by a vertically adjustable roller 76 which may effect a slight additional bending.
