Abstract

511,106. Flanging. BLACKBURN AIRCRAFT, Ltd., and MacARTHUR, W. W. Sept. 21, 1938, No. 27515. [Class 83 (iv)] Apparatus for dimpling or flanging rivet holes in metal plates comprises a yoke 12, 13 for embracing the work, an anvil 11 supported by the limb 13 of the yoke, a co-operating punch 10 slidably mounted in the other limb 12 of the yoke, a pressure pad 28 surrounding the lower end of the punch and a spring 31 disposed between the pad and an abutment 32 on the punch for holding the pad against the plate 15 during the operation of the punch. The anvil is formed at the upper end of a hollow cylindrical plug 21 screwed into the limb 13 and carrying an adjusting nut 16. Within the plug is mounted a location peg 17 adjustably loaded by a spring 18 so as to project upwardly into the hole in the plate. Fixed to the lower end of the punch is a flanging tool 22 formed with a guiding pin 23 and with a conical portion 24 of the shape of the required flange. The anvil has a corresponding conical depression 25. The punch is operated by a hammer blow on its free upper end which projects through the limb 12 of the yoke.
