Abstract

Process and apparatus for making a metal annular member of precise tolerances and desired surface finish. An external die has a continuous die surface of the configuration desired for the external surface of the metal annular member and an annular ridge surrounding the inside of the die for seating one end of an annular sheet metal blank. A first punch engages the sheet metal blank and drives it into the external die so as to reduce the external diameter of the blank and seat it against the ridge. The precise tolerance of the die surface of the external die determines both the external and at least a portion of the internal dimensions produced in the annular sheet metal blank. The first punch is axially movable to an endmost position wherein substantially all of the blank has been forced into the die. An ejector punch is positioned inside of the external die and operates to provide a portion of the forming die surfaces as well as to eject the completed workpiece.

Claims (1)

PatentkravPatent claims 1. Satt att med snava mAttoleranser tillverka en metallhylsa, varvid ett i tvarsektion cirkulart metallamne placeras mellan en stans och en dyna och sedan med stansens hjalp tvingas ned I amnet, k annetecknat av att amnet bibringas rorform genom bockning av ett plant plAtamne mellan tvA parallella valsar, vilka deformerar amnet till rorform, varefter de intill varandra belagna kanterna sammanfogas. 11. Set to manufacture a metal sleeve with tight material tolerances, wherein a metal blank circulating in cross section is placed between a punch and a pad and then forced into the blank with the aid of the punch, characterized in that the blank is rudder-shaped by bending a flat plate between two parallel rollers, which deform the blank into a rudder shape, after which the adjacent edges are joined together. 1
