Abstract

See full text

A method for forming a spanner includes following steps: preparing a cylindrical metal blank, heating the metal blank to become softened, shaping the metal blank by pressing and pushing the metal blank forward on a shaping die with a pushing unit to form two head sections and a holding section connected between the head sections, and stamping the metal blank when the metal blank still has residual heat to flatten the holding section and shape each head section into a spanner-shaped part. Therefore, a spanner product is made. The method simplifies the processing procedures, decreases residual materials, achieves a quick shaping operation, reduces processing costs, and increases the forming efficiency.
