Abstract
111,280. Inshaw, J. G., and Inshaw, G. R. Nov. 14, 1916, [Convention date]. Rolling tubes; mandrels; separating mandrels from work.-In a pilger tube-rolling mill, the mandrel mounting and operation and the means for stripping the work are improved. The hollow billet is held by a support and stop W, Fig. 1, operated by an hydraulic cylinder w<4>, while a mandrel G is inserted. The mandrel is connected by a bayonet joint described in Specification 111,295 to a tubular member B<2>, Figs. 3 and 4, rotatably mounted on a carriage B which is advanced by an hydraulic cylinder b<2>. The tubular member B<2> slides on a square rod j<2> which can be connected by the hydraulically operated clutch K to a shaft j, intermittently rotated by means of gearing M described in Specification 16292/15 from the shaft L, Fig. 1. This shaft is rotated through gearing l<3>, u' from the roll-driving gear which is of the kind described in Specification 25886/09, one or two motors Q<2> being employed. The mandrel G has a collar D<2> adapted to be moved relatively thereto by hydraulic cylinders D<3> to strip or feed the work, and to allow the last part thereof to pass between the rolls. The work is removed from the mandrel by lowering the rollers of the stripper shown at the left of Fig. 1 and described in Specification 111,296.
