Abstract

1419914 Forging; making crank or connecting rods VYZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI 10 May 1974 [14 May 1973] 20890/74 Headings B3H and B3A An elongated forging is made by placing a length of rolled stock in a cavity 1a of a die part 1, forging the stock using die parts 2, 3 movable transverse the stock axis followed by a second forging using a die part 4 movable axially of the stock. The die part 4 causes upsetting of the ends of the stock enclosed by the die parts 1, 2, 3. The rolled stock is produced by cross wedge rolling and has a volume for unit length distribution approximately the same as that of the elongated forging. The forging may be a pedal crank or a connecting rod of a two stoke engine.
