Abstract

1,084,459. Making bearings; stamping. KAYDON ENGINEERING CORPORATION. April 13, 1966 [Sept. 2, 1965], No. 16243/66. Headings B3A and B3Q. [Also in Division F2] A thin hardened steel bearing shell for a ball or roller bearing, has a re-heated and airhardened radially-inwardly directed flange formed at one end thereof. The shell 40, Fig. 1, is placed within a die-set 10 which comprises an upper die assembly 12 and a lower die assembly 14. The upper die assembly 12 comprises a die 16 secured to a back-up member 18 which is held by flanges 20 and bolts 22 to a mounting- plate 24. The die 16 is made of tungsten carbide and has a cavity 26, Fig. 2, having a tapered side-wall 28 and a bevelled cornerwall 30. The lower die assembly 14 comprises a die 32 which incorporates a heat-sink ring 34 and is supported on a mounting-plate 36. The die 32 and the ring 34 are provided with a cavity 38 which receives the shell 40 having outwardly-tapering side-walls. The die set 10 is mounted in a resistance welding machine, with the upper and lower die assemblies 12 and 14 serving as the electrodes of the machine. A cage 42, rollers 44 and a seal 46 are positioned in the shell 40 and the upper die assembly 12 is moved downwardly to effect electrical contact. The upper edge of the shell 40 is heated to a plastic state and then the upper die assembly is forced downwardly to deform the upper edge of the shell 40 into the radially-inwardly directed closing flange 48, Fig. 5. The heat-sink ring 34 prevents the main body of the shell from being overheated. The flange 48 shrinks upon cooling and draws the tapered side-wall of the shell radially-inwardly; and the flange 48 becomes air-hardened.
