Method of forming a torsion bar with hexagonal heads

To make a metal torsion bar having an elongate central body connected to two hexagonal end heads via shoulders, the ends of a torsion bar blank are initially upset while hot so as to form the shoulders of the torsion bar together with cylindrical head blanks, after which each head blank is machined...

description To make a metal torsion bar having an elongate central body connected to two hexagonal end heads via shoulders, the ends of a torsion bar blank are initially upset while hot so as to form the shoulders of the torsion bar together with cylindrical head blanks, after which each head blank is machined by removing material until the corresponding hexagonal head has been obtained.
