A spring is a mechanical part that USES elasticity to work. The parts made of elastic material are deformed under the action of external force, and return to original condition after removing external force. Also known as a spring. It is usually made of spring steel. The types of springs are complex and diverse, according to the shape, the key is compression spring, stretch spring, torsional spring, shaped spring and so on. In particular, Shanghai, Zhejiang, Jiangsu, Guangdong, Shandong and other regions have developed rapidly, while other regions have developed to different degrees, which are generally better than other industries. Next say how does opposite sex spring manufacturer produce spring.

There are two key methods for spring production:

1. Cold forming: The cold forming process can only be automated once. Cold forming machine has been developed to 12 claws. The steel wire within the range of (0.3 ~ 14) mm can be formed at one time in the 8-claw forming machine. Development direction of forming process equipment:

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

(2) Improve the durability of the equipment by improving the fineness of the equipment parts and strengthening the heat treatment effect.

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

2. Hot forming: The speed of hot forming process can be realized. China's (9~25) mm specification of the forming only CNC2 shaft hot coil spring machine, the speed of 17 pieces per minute. Compared with the prosperous countries, there is a big gap. Large spring hot forming process control ability. Because there is only CNC2 axial spring coiling machine, the shape control has less three directions, and the precision is poor. And there is no automatic bar rotation control and adjustment mechanism, so the degree and ability of hot coil spring forming is low. Therefore, the accuracy of the spring and the degree of decarbonization of the surface oxidation is also low.
