Abstract

1,199,085. Extruding; forging. KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE A.G. 29 Oct., 1968 [7 Nov., 1967], No. 51179/68. Headings B3H and B3P. A device for cold-forming metal billets into cups comprises a die, an ejector and a punch whose tip is convex and ends in a point on the axis of the punch. The ratio of the height h of the tip to the diameter D is between 52 and 66%, preferably about 57%. The angle defined by the surfaces at the point is between 168 and 120 degrees and linearly related to the ratio h: D. The convex part may comprise segments of circles with their centres of curvature M 1 , M 2 offset from the axis or the part may have a polygonal outline, Fig. 1 (not shown). The cups produced are tall with thick walls and/or small bottom thickness. The billet is made of steel or copper. The forming may be completed in one operation or a number of operations with or without intermediate recrystallization annealing.
