Title: Torsion bar manufacturing method, and torsion bar
Inventor: YOSHIMURA MOTONOBU
IPC: F16F1/14
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To reduce a manufacturing cost by simplifying working contents in a torsion bar manufacturing step.  <P>SOLUTION: A torsion bar manufacturing method includes a first shaping step 11 of setting the hardness from the inside to an surface layer part to be ≥320 in terms of Vickers hardness (Hv) by contracting a round bar steel by the cold drawing, and a second shaping step 12 of obtaining a small diameter spring part 2 by cutting an area in the middle of the longitudinal direction of the round bar steel. The manufacturing cost can be reduced by omitting, for example, the post-treatment related to the thermal hardening treatment because no thermal hardening treatment including a factor of increasing the cost in a conventional example is performed.  <P>COPYRIGHT: (C)2003,JPO
