Abstract

612,684. Angular bending; stamping. GREEN, L. B. May 30, 1946, No. 16451. Convention date, June 21, 1945. [Class 83 (iv)] In a machine for bending flanged sheets by clamping the sheet between a stationary die 13 and a die 16 on a carriage 17 moved by a hydraulic cylinder 31 bending arms 24 swung about pivots 26 by hydraulic cylinders 42 effect bending whilst the flange is restrained between the die 16 and projections 24a on the arms 24. The die 16 is mounted on a carriage 17 pivoted on a post 18 on the slide 15 and is moved normally to the bed 11 by a hydraulic cylinder 19 for removing completed work by an ejector 62 operated by cylinder 61. To prevent canting of the die 16 during operation, lugs 56 on the carriage 17 engage lugs 57 on the slide 15 and a projection 59 on the slide engages a recess 58a on the frame. A wedgeshaped arcuate thrust member 52 on the slide 15 engages the rear of the carriage 17. The fixed die 13 is supported by a thrust abutment 39 secured to the frame. Oil pressure for the cylinders is provided by a pump 35.
