Abstract
550,186. Upsetting; flanging. THOMPSON PRODUCTS, Inc. Jan. 13 1942, No. 532. Convention date, Feb. 17, 1941. [Classes 83 (ii) and 83 (iv)] Flanges are formed at the ends of tubes by electrically heating, applying axial pressure to upset the ends and whilst the metal is still hot forging to the required shape of flange. A tube blank A is mounted between two part dies 10 held by half bushes 12, the dies being raised by springs 25 as permitted by pins and slits 24. The die R carries a screwed ring 19 that fits the interior of the tube a flanged ring 20 that engages the end of the tube the flange being engaged by a spring 21, and an abutment ring 26 normally depressed by a spring 271 as limited by pins and slots 29. In operation current passes to the work from the dies 10 and abutment 17, and on descent of the die R the end of the tube is first upset at f, then the end of the ring 19 forces all the upset outwards and the abutment ring 26 presses down the dies 10 to form the flange by its shaped end 30. After cleaning by sand blast the cold tube is turned in dies and flash is removed from the flange by turning. A form of machine for operating the dies is described in U.S.A. Specification 1,870,987.
