Abstract

856,877. Feeds for rolling-mandrels. DALMINE S.p.A. Feb. 8, 1957 [April 28, 1956], No. 4355/57. Class 83 (4). In a pilger rolling-mill with reciprocating rolls, the mandrel carriage A, Fig. 1, is moved for feeding, stripping, return, &c. by a rotary nut 4 which is axially fixed in the machine frame B and engages a threaded rod 3 attached to the mandrel carriage A. The nut is driven at high speed by a motor 5 for fast forward and return motion, the drive including a magnetic brake 8 to prevent overrunning. For slow feeding and stripping operations the nut is driven by a motor 6 through a reduction gear 7 and an electromagnetic coupling 9. In a modification a single motor may drive the nut through change-gear means.
