Coil Spring Manufacturing Equipment
Our coil spring manufacturing machines can produce various types of coil springs.
These coil springs are used for automobiles, trains and heavy machines.
We have made the machines for wire diameter up to 100mm.
STEP 4SETTING
Setting Machine
The purpose setting process is to improve fatigue strength of coil springs, and enhance its elastic limit. Setting process can identify "specified load" or "specified height" of coil springs.
Cold Setting UnitB663S
Overview
This is an equipment to make a setting of coil springs after shot peening in a normal temperature two by two. The machine has a function to cool a coil spring, which is peened in a hot condition. Coil Springs after setting are hooked to hanger conveyor for painting. Jigs, which are changed in accordance with shapes, can be automatically changed by jig changer (Option).
Constitution
- Cooling Device by water
- Setting Machine
- Jig Changer (Option)
- Hooking Device (to painting hanger)
- Positioning Device and Transfer Device

Warm Setting UnitB564W
Overview
This is a equipment to make a hot setting of coil spring, which is extracted from the tempering furnace, two by two. Coil springs after hot setting and cooling by water are transferred to shot peening. Jigs must be changed in accordance with shape of both spring ends and can be changed by automatically by jig changer (Option).
