Abstract

667,323. Angular bending. PIDCOCK, J. Feb. 17, 1950, No. 4160/50. Class 83 (iv). A press brake has a framework built of section irons with an upper stationary toolcarrying beam 7. The lower tool is supported by a H-section cross-head 4 raised by hydraulic jacks 16, 17, 18 equally spaced on a basemember. Screw stops 29 carried on the crosshead contact the beam 7 to limit the upward movement. A motor-driven oil pump 25 supplying pressure to a line 17 has a relief valve 27. The press is operated by closing a return valve 24. A hand pump may be fitted.
