Abstract
996,023. Cupping; extruding; drawing. HARD ALLOYS Ltd. March 22, 1963 [March 30, 1962], No. 12342/62. Headings B3P and B3Q. A drawing, extrusion, forging or sizing die of the type in which an insert defining the die aperture is supported in a bolster or case comprises spacing means 3 disposed between the insert 8 and bolster or case 1, said means being so constructed as to be incapable of being circumferentially stressed to exert any significant compressive loading on said insert and serving merely to transmit the compressive loading from the bolster to the insert. The insert of tungsten carbide, cermet or ceramic is shrunk or press-fitted into the metal spacer or bolster and retained therein by an annular plate 7. The steel spacer is divided by equi-spaced radially inwardly or outwardly extending slots 4 terminating in bulbous portions 6 to form ten to twenty, preferably twelve, interconnected spacer members 5 and is retained in the bolster in a known manner. The external surface of the insert and the bore of the spacer may be conical or cylindrical. Alternatively, the spacer may be an integral part of the bolster having a plurality of straight or arcuate outwardly extending radial slots to provide twelve or eighteen spacing members 5, or may comprise a plurality of separate spacers 5 equispaced between the bolster and insert. The die may be used to deep draw closed and steel cylinders at elevated temperatures.
