Abstract

844,219. Forging. KOCKS G.m.b.H., F. June 13, 1957 [July 31, 1956], No. 18704/57. Class 83 (4). A swaging-apparatus comprises two pairs of jaws 5, 17, movable in mutually-perpendicular planes and acting alternately on a central workpiece, the jaws of each pair being actuated by an eccentric or crank mechanism 1-4 whereby they close together to squeeze the workpiece, move along in the feed direction of the workpiece to stretch the latter, and then open to release the workpiece and return to their initial positions. Each vertically-moving jaw 5 is actuated through links 26, 31, Fig. 5a, by a pair of eccentric shafts 1, 2 and 3, 4, respectively driven through gearing 7-12 from a drive coupling 6. Each hoiizontal jaw 17 is actuated through links 26, 31 by a pair of eccentric shafts 13, 14 and 15, 16 respectively driven from the shafts 1-4 by bevel gearing 18-21. The link pins 27 are designed to fracture if the jaws are overloaded. Guide projections 22 are provided on the jaws. Each jaw, Fig. 4a, may comprise a main forming region 23 of radius R 1 , R 2 and a smoothing region 25 of radius R 3 . Other forms of jaw contour are described. The workpiece may be of square, circular, or hollow circular section.
