Torsion spring is a kind of mechanical parts use flexibility to work.
Usually made from spring steel.
Used to control the movement of the parts, moderate impact or vibration, regenerative energy storage, such as the size of the measuring force.
Widely used in computer, electronics, electrical appliances, cameras, instruments, door, motorcycles, harvester, cars, etc.
1, the torsional spring cold forming process of cold forming process of one-time automation capabilities.
Cold forming machine at this stage has grown to 12 feet.
In the (
0.
3 ~ 14)
Within the scope of the mm steel wire, basically in eight claw machine can forming at a time.
At present the development direction of molding process equipment:
(
1)
Improve molding speed, the key development trend is to improve molding speed machine equipment, the production efficiency.
（
2)
According to precision of hoisting machinery and equipment parts and strengthening heat treatment effect to improve the machine durability.
（
3)
Increase the length of the sensor and a laser range finder, for CNC forming machine to carry out the automatic closed-loop control manufacturing process.
2,
torsion spring, the hot forming process of hot forming process speed ability.
At this stage in China (
9 ~ 25)
The molding on mm only CNC2 shaft hot spring coiling machine, maximum speed 18 per minute.
Compared with the developed countries under the gap is bigger.
Large torsion spring hot forming process control.
