| 11 | Finished products | 1) Spring wires produced by this production line would keep uniform and straight; 2) Products keep consistence with EN10270-2:2011, tensile strength fluctuation of the same coil of spring wire would be ≤50MPa |
III. Fetures
1. The servo motor controls the spring coiling, the spring pitch ,the feeding angle, etc. separately.
2. With G code programming, the control form is more flexible. The machine can store the code, the production process can be controlled by the program itself, the winding speed can be adjusted.
3. It cvan flexibly control the spiral angle of the end ring and the pitch of the middle part, and can control the height on the spring. No manual intervention is required after the winding is completed.
