Abstract

920,732. Forging. BUNDY TUBING CO. Nov. 16, 1961 [Dec. 23, 1960], No. 40974/61. Class 83 (4). A metal working press, particularly a header, comprises a pair of parallel crank-shafts 100, 102 journalled in a frame 24, one of the shafts 102 driving a reciprocable tool carrier 170 and the other shaft 100 driving through a wedge device 132 a transversely movable work-holding jaw 56. The two crank-shafts are driven through gearing, a flywheel and a belt by an electric motor 112, Fig. 1 (not shown). Jaw 56 is biased downwardly and forwardly by an inclined spring 66 and co-operates with a fixed upper jaw 52. Crank-shaft 100 carries an arm 130 with rollers 134, 136 co-operating respectively with inclined surface 138, 140 on a pivoted arm 142, and the jaw 56. Arm 142 is supported by a rubber body 154 which can yield to admit different sizes of workpiece W into the jaws. The tool carrier 170 carries a pair of tools T which are aligned with separate parallel grooves in the jaws into which the workpieces are moved successively for deforming in two stages. Carrier 170 slides on a guideway 172 and is held above by an adjustable wedge 174.
