Spring two forming process

(1) spring cold forming process

1) cold forming process one-time automation capabilities. Cold forming machine has been developed to 12 claws. In the range of (0.3 ~ 14) mm, the wire is basically formed at the time of 8 claw forming. The current direction of the development of process equipment:
    ① to improve the forming speed, the main trend is to improve the equipment forming speed, that is, production efficiency;
    ② by improving the precision of equipment parts and strengthen the heat treatment effect to improve equipment durability;
    ③ increase the length of the sensor and laser range finder, CNC machine to the automatic closed-loop control manufacturing process.

2) cold forming process range capacity. The current large diameter spring coil spring machine, the maximum specifications up to 20mm, 2000MPa, spiral than 5. Minic-Block spring and eccentric spring cold forming process is still limited.

(2) spring thermoforming process

1) Hot forming process speed capability. At present, China's (9 ~ 25) mm specifications on the formation of only CNC2 axis hot coil spring machine, the maximum speed of 17 per minute. And the developed countries compared to the larger gap.

2) large spring thermoforming process control capability. Because only CNC2 axis hot coil spring machine, so the shape control less three directions, the accuracy is poor; and no automatic bar rotation control and adjustment mechanism, so the hot coil spring forming process level and ability is low. So the accuracy of the spring level and surface oxidation decarburization level is also low.
