Abstract
773,482. Drawing; forging. AJAX MANUFACTURING CO. Sept. 23, 1955, No. 27243/55. Class 83 (4). In a wire-drawing machine having a reciprocating die 15, Fig. 1, and from which the wire is fed directly to a cold-heading machine &c., a gripping device 16 operating in timed relation to the drawing operation is adapted to stop the wire after a predetermined length of feed. The gripping device 16 comprises a pair of wedgeshape jaws 26a, Fig. 9, movable on ball-bearings 49 in a housing 42 and during the idle stroke of the drawing die when the wire is being fed forward by feed rolls 12, the jaws 26a are automatically closed by push-rods 62 to grip the wire after a given length of feed. The rods 62 are actuated by a cam 58 which is rotated in timed relation with the heading-machine. The cam 58 rocks a lever 59 engaging a plunger 56 mounted in the gripping device 16 and containing a spring 61 which presses against the pushrods 62 through a seating 63. The gripping device is mounted on trunnions 40, 41 and is rotatable to any angle through a worm gear sector 84 operated from a manually rotated shaft 80 so that the jaws 26a which may have a non- uniform pass 16a, Fig. 7, for keystone &c. sections may be turned to orientate the work at the angle required for the heading machine. The jaws 26a are yieldingly located in position by spring-loaded plungers 52 and other springs 50, 53 (not shown), and are operable by frictional drag to grip the work and prevent its movement backwards during the drawing stroke. The die 15 is mounted in a box 14 which is slidably mounted on guides 19, 20. During the drawing stroke it is moved by an arm 22 which engages a flat face 25 on the box and is reciprocated by an eccentric 37 on the same drive-shaft 32 as the cam 58. For initially pushing the work through the die 15, inching devices 17, 18 are provided. The device 17 is reciprocated from the arm 22 by link 27 which can be held out of engagement with the arm 22 by a manually-operated pivoted member 29 during the normal drawing operation.
