Abstract

686,479. Billet - piercing. TAYLOR & CHALLEN, Ltd., and CHALLEN, H. D. July 27, 1951 [Aug. 3, 1950], No. 19368/50. Class 83 (iv). A power-operated press of the kind in which a heated billet is held between the die faces of a vice during a piercing operation and wherein the operation of the vice and the clutch of the press is effected pneumatically is characterized by the provision of a valve in the pneumatic supply line for actuating, the clutch, said valve being opened when the vice is closed. A manifold 5 supplies pneumatic pressure through a pipe 6 to a hand-operated three-position valve 8 controlling the opening and closing of the vice and through a pipe 7 connected through a spring-loaded valve 9 and a spring-loaded footoperated valve 10 to a cylinder 11, the piston of which is connected to the clutch-operating rod 13 of the press. The valve 8 is connected to both ends of a pneumatic cylinder 16 by pipes 15 and 17. A double-acting piston in the cylinder is connected to one arm of a bellcrank lever 19 the other arm being connected by a link 20 to a lever 21 pivoted at 22 and connected to the movable die 23 of the vice by linkwork 25. The lever 21 carries a cranked arm 26 having an adjustable stop 27 which engages the plunger of the valve 9 when the vice is closed, thus automatically opening the pipe 7 as far as the foot-operated valve 10. The valve 9 ensures that premature operation of the valve 10 will not operate the clutch of the press until the vice is closed.
