Abstract

1293399 Pilger mills VALLOUREC (Usines a Tubes de Lorraine-Escaut et Vallourec Reunies). 30 Dec 1969 [31 Dec 1968] 63399/69 Heading B3M A pilger rolling mill includes a roll-carrying cage 1, Fig. 1, which is reciprocated by a crankdrive 4, 5, and an indexing assembly for intermittently rotating a tube being rolled. The indexing assembly incorporates gearboxes 15- 19 which are driven from one of the cranks, the gearboxes 18 and 19 transforming a continuous rotary input to an intermittent rotary output. Jaw units 9 and 10 are driven from the gearboxes 18 and 19 to rotatably index the tube. A similar gearbox 20 drives a jaw unit 11 coupled to a mandrel which supports the tube. The tube is also longitudinally indexed during rolling, by means of a slidable carriage 24. The carriage is driven by a threaded rod 18, or alternatively can be driven by a shaft 12 associated with the gearboxes 18-20. The rod 28 is rotated by an hydraulic motor 29 which is coupled to a pump 31 driven by one of the cranks. A fluid-pressure source 32 is provided for rapidly returning the carriage. The carriage supports a pivoted arm 26 which is reciprocated by means of a cam in the carriage. The cam is continuously rotated by a shaft 27, Fig. 1, driven from a gearbox 28. The arm acts on the end of a spring-loaded sleeve 43, the sleeve supporting an inner tube 45. A detent 46 is carried by the tube 45 and engages the end of a tube being rolled, to prevent return of the tube.
