Abstract

1454299 Tube expanding MANNESMANNMEER AG 20 Dec 1973 [28 Dec 1972 6 March 1973] 59243/73 Heading B3J To accommodate pipes of different diameters the level at which a tube expander is supported is adjustable. In one form, Fig. 1, the expander is mounted on two pairs of eccentrics securable by clamps 15 after adjustment. The eccentric shafts 17 are driven, through clutches (19) and worm gears (18), by a motor (20), Figs. 2 and 3 (not shown). The expander is expanded by a tapering core 2 operated by an hydraulic cylinder 10, and a yielding support 12 is provided for the tube 24. In another form, Fig. 4, a beam 26 carrying the expander is supported adjustably at each end by two pairs of slides 29 which are traversed along tracks 30 by lead screws 31 driven through clutches 33 by one or more motors 35. Bearings 28 in the slides 29 engage tracks 27 on the beam and are angularly adjustable to accommodate elevating only one side of the beam to facilitate alignment of the mandrel and pipe. An adjustable support 37 is provided for the pipe.
