Abstract: A method for manufacturing a wrench handle includes preheating a work piece made of metal, with a layer of carbon scale being generated on the work piece during preheating. The preheated work piece is forged/pressed to form a wrench handle, with the carbon scale on the work piece being forged into upper and lower faces of the wrench handle. An indentation is formed on each of the upper and lower faces of the wrench handle. The carbon scale is then removed, leaving pits in the upper and lower faces of the wrench handle, with the pits concealed by the indentation sections.

Abstract: Apparatus for the automatic manufacture of drop forgings, particularly wrhes, from split-off and stamped workpieces comprises prebending means having a stationary bending jaw and a bending jaw which is movable in a horizontal plane, transfer means, and a power hammer which is disposed below the prebending means and has forging dies which are oppositely movable in a horizontal plane.
