Abstract
781,951. Making bearings; forging. GLACIER METAL CO., Ltd. Jan. 30, 1956 [Feb. 10, 1955], No. 3976/55. Classes 83 (2) and 83 (4). A plain cylindrical bearing is made by cutting a rectangular blank from metal strip or sheet, bending the blank into substantially cylindrical form whose wall thickness is less than and length greater than that of the finished bearing, confining the blank in an annular die chamber 5 whose inner and outer cylindrical walls have substantially the same diameters as those of the finished bearing, and upsetting the blank into close contact with the walls of the die chamber. The initial blank, which may be preformed with one or more oil grooves and/or oil holes by pressing and punching, is bent around a cylindrical mandrel 2 whose diameter is equal to the internal diameter of the finished bearing. The mandrel and blank are then inserted in the die 5 and the blank is upset between shoulders 4, 7 on the mandrel and die. The upset blank is withdrawn with the mandrel and is stripped therefrom by engagement with a stationary sleeve 12, Fig. 4 (not shown), surrounding the mandrel. In an alternative form of mandrel the shoulder 4 is provided by a sleeve 10, Fig. 6, surrounding and moving with the mandrel. Chamfered ends may be formed on the inner and outer surfaces of the bearing by means of corresponding lips 13, 14, 15, 16 on the die and mandrel. Alternatively, chamfered portions 13, 14 only are provided on the mandrel and die, Fig. 5 (not shown), whereby in a final pressing operation an inner chamfer is provided at one end and an outer chamfer at the other end of the blank, Fig. 7 (not shown); thereafter the blank is reversed in the die and the pressing is resumed to form chamfers on the other two edges.
