Abstract

1,139,809. Making bearings; curving; rolling. ASSOCIATED ENG. Ltd. 6 May, 1966 [12 May, 1965], No. 20129/65. Headings B3A, B3E and B3M. Apparatus for forming a cylindrical member, e.g. bush or bearing, comprises a die cavity 2 defined by a rotatable mandrel 3 and the cavity wall 2a into which a strip S is fed and deformed therein to the shape of the die cavity. The strips are fed individually from a magazine (14), Fig. 3 (not shown), by a reciprocating push-rod 11 through a slot 13. The mandrel 3 is preferably rotated in a direction to oppose the strip feed and may have surface rollers 8 or surface projections. If desired the cylindrical member may be composed of a number of arcuate portions in which case correspondingly smaller strips are fed successively to the die cavity. When the strip has completely entered the die the plunger 16 is raised to shape the rear end of the strip. The formed member is ejected by an electrically, mechanically or hydraulically operated sleeve 10 mounted on the mandrel shaft from the cavity either into a space between the cavity 2 and a forming die cavity 9 or directly into the forming die cavity. In the forming die cavity the ends of the strip are butt-jointed together. The ends of the strip may be plain, inclined or notched in a complementary fashion. The apparatus may be arranged with the mandrel shaft horizontal or vertical.
