Leaf Spring Making Plant

Abstract

The spring is one of the mechanical elements making maximum use of the elasticity of material and the energy absorption capacity. It has such functions as shock absorption, anti-vibration (suspension spring), maintenance of constant force or torque (valve spring, spring washer, watch spring), and indication or adjustment of load and torque (scale spring, manometer). Mainly, the material of spring steel is heated (approximately 900°C) for forming to be formed into the spring, with the material used hereby called the hot-formed material. For the reason, it is applicable mainly for large-size plate spring (leaf spring), coil spring and torsion bar rather than small-size spring.
