Abstract
1536292 Flanging; seaming; corrugating W ECKOLD AG 17 Sept 1976 [24 April 1976] 38606/76 Headings B3E and B3J [Also in Division B5] Apparatus for carrying out a mechanical operation in a pipe comprises a frame, a twopart pipe clamping ring, one part of which is secured to the frame and in which are received replaceable pipe-clamping jaws, and a tool support which is rotatably mounted within the frame. In Fig. 4, the apparatus comprises a frame 10 with a mounting flange 12 and a fixed lower half-clamping ring 16 to which an upper half clamping ring 18 is hinged. The ring halves can be secured together so as to enclose clamping jaws 24, 26 selected to grip one end of a pipe to be worked. The frame 10 also provides the outer race 34 of a ball bearing, the inner race 40 of which forms the tool support and is rotatable through chain drive 42 or meshing gears either by a hand wheel or by an electric motor. In Fig. 4 the tools are seaming rolls 168, 170 radially adjustable at 172 on a ring 160 secured to race 40 by bayonet fittings 60 and screw pin 70. The jaws 24, 26 are secured round a suitably flanged pipe end, and another flanged pipe end is placed in position for seaming, and held by folding the flange by hand at two points. Conical roller 168 is then advanced and partially forms the seam in one or two revolutions, then the seam is completed by advancing roller 70. Fig. 2 shows a flanging tool, comprising disc 64 having bayonet fitting 66 for attachment to race 40. A flanging roll 80 is traversable radially along a slot 72 in the disc by lead screw 84, the roll being yieldable inwardly relative to the lead screw by compression of spring 82. The roll is displaced progressively outwardly as flanging proceeds, either by hand wheel 108 or automatically at each revolution by star wheel 120 striking a fixed pin 122. The jaws 24, 26 may be shaped to hold the pipe in an oblique position so as to flange a mitred tube. The roll may form a corrugation round a tube. Figs. 5 and 7 show an embodiment in which a corrugated mandrel is placed within a tube and a corrugating roller 186 is revolved about the tube, being radially traversable by lead screw 194 and hand wheel 192 along its mounting disc 180. The mandrel has teeth 200 engaging the corrugating teeth 186 of the roller, and is contractible for removal, comprising an inner conical support 196 and four tapered outer parts 210 surrounded by tension spring 214. The spaces between the outer parts when in their expanded position are arranged to fall in corrugating grooves of the mandrel surface.
