Abstract
1277045 Making rings; angular bending; shearing A T RICHARDSON & SONS PTY Ltd 10 Sept 1969 [26 Sept 1968] 44593/69 Index F2T 37E1R A method of making a metal ring comprises cold-pressing a round wire or bar into a barrelshaped cross-section, having two opposed flat sides linked by convex sides, forming the wire or bar into a ring and cold-pressing at least three sides of the cross-section of the ring to produce the ring. If the internal diameter of the ring is critical the ring is welded then pressed by platens 6 and 7 after pushing an oversize mandrel 8 through the ring, Fig. 3 If both internal and external diameters are critical a modified platen 7a is used, Fig. 5. For producing split piston rings the formed ring is not welded but fitted into a sleeve 13 and pressed by platens 6 and 7, Fig. 6. If both internal and external diameters are critical then one of the platens 6 or 7 may have a surface (11a), Fig.7 (not shown), for pressing the internal diameter whilst the outer diameter is formed by sleeve 13. An apparatus for producing the rings comprises two pressing rolls 14, 15, of which at least one, preferably 14, is driven, which form a round wire or bar 2, which is guided to the rolls by means 15, into a barrel-shapedcrosssection 3, a means for forming the flattened wire or bar 3 into a ring and a shear means 21 operated through a linkage 22 for shearing off a predetermined length to form a ring. The means for forming the ring may be a roller 17 or a shoe 18 both of which are adjustable to produce rings of any desired diameter.
