Abstract

842,386. Sizing bores of tubes. UNIVERSAL STEEL TUBE CO. Ltd. June 3, 1957 [June 2, 1956; June 6, 1956; June 12, 1956], Nos. 17115/56, 17412/56 and 18073/56. Class 83 (4). Means for surface finishing the bore of a metal tube comprises a mandrel 6 carrying one or more annular sets of rollers 4a, each roller being mounted in a cavity 5a in a carrier 5 forming part of the mandrel with the axes of the rollers angularly offset to the axis of the mandrel. During the finishing operation, the tube which may have been honed is enclosed in an outer casing, preferably in two parts hinged together to facilitate removal of the tube. The forward end of the tube may be belled out to prevent longitudinal movement. An hydraulic ram is preferably used to drive the mandrel which is cooled and lubricated by oil during working. The rollers are preferably barrelshaped and the cage 5 is attached to or integral with the mandrel body 6. The rollers are held in place within the cage, during their insertion into the bore, by a slidable sleeve 7 or they may be retained in position by magnetization of the rollers and/or cage. The rollers are rotatably mounted on axes lying in a transverse plane or in an oblique plane; in the latter case the mandrel is rotated during feeding. Two or more sets of rollers may be of successively increasing overall diameter. With a single set of rollers two or more passes with intermediate rotation of the mandrel are necessary.
