A torsional spring is a mechanical part that USES elasticity to work. It is usually made of spring steel. It is used to control the movement of machine parts, mitigate impact or vibration, store energy, measure force, etc. Widely used in computers, electronics, home appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles, and other industries!

1. Cold forming process of torsion spring One-time automation capability of cold forming process. The cold forming machine has now developed to 12 claws. The steel wire in the range of (0.3 ~ 14) mm can be basically molded once in an 8-claw molding machine. The development direction of molding process equipment at the present stage:

(1) To improve the forming speed, the key development trend is to improve the forming speed of machinery and equipment, namely, production efficiency.

(2) To improve the durability of machinery and equipment according to the precision of machine and equipment parts and the actual effect of heat treatment.

(3) Lift the length sensor and laser rangefinder to carry out the whole process of automatic closed-loop control manufacturing for CNC forming machine.

2. Thermal forming process of torsional spring. At present, China's (9~25) mm molding only CNC2 shaft hot spring machine, the maximum speed of 18 pieces per minute. Compared with developed countries, the gap is large. Large torsion spring thermal forming process control ability.
