Method of forming socket wrenches

Abstract

An improved method of forming forged socket wrenches in a manner vitiating the need of further machining operation. Steel having a predetermined composition is received in coil form and treated with a lubricating coating. The coiled steel is then straightened and an initial billet of steel is cut to an appropriate size. The billet is then squared to establish opposing longitudinal surfaces in parallel relation with respect to each other and further to provide a working metal billet with a predetermined volume. The metal billet is then positionally located adjacent to a female die in order to provide a bearing surface to form a taper on at least a portion of the external surface of the metal billet. The socket wrench is then cold formed by the impacting of longitudinally opposing surfaces of the metal billet with a pair of metal dies to form the taper on the external surface of the billet and to provide a through opening of non-continuous contour in order to receive a driving tool on one end of the socket wrench and to receive a nut, bolt or other element of predetermined contour on an opposing end of the socket wrench.
