Abstract

480,201. Squirting. HEAD, WRIGHTSON, & CO., Ltd., and LAKE, N. C. Nov. 17, 1936, No. 31458. [Class 83 (iv)] To effect separation of the back die and shell after extrusion of metal particularly non- ferrous metal, a metal piercing clamp first engages the shell part to be cracked and a shear blade then operates to remove the butt end. As shown, a fixed ram 1 has mounted thereon a cylinder 5 carrying the movable shear blade 6 and also a smaller cylinder 7 in which works a ram 8 carrying a clamp 9 provided with V-shaped hard metal strips 10. A part 11 communicates between the two cylinders, and when fluid is admitted the pressure built up moves the small ram 8 with its clamps before the cylinder 5 and its shear blade is operated. Rams 16 working in cylinders 17 transmit movements to wings 15 attached to the cylinder 5 for the return movement. The work is placed in a semicircular trough 22.
