The processing head 9 can be easily taken out from the inside of the slide groove 11, which is more convenient than traditional bolt fastening during disassembly and replacement. In addition, the processing head 9 can be extended into the depth of the slide groove 11 so that the two clamping holes 10 are both clamped by the locking rod 5, so that the use length of the processing head 9 can be adjusted.

[0023] Reference Figure 1-Figure 3The buffer assembly includes a telescopic rod 13, one end of which is fixedly connected to the outer side of the sliding seat 3, and the other end of the telescopic rod 13 is fixedly connected to the cutting head 15. The outer sleeve of the telescopic rod 13 is provided with a spring 2 14, one end of the spring 2 14 is fixedly connected to the outer side of the telescopic rod 13, and the other end of the spring 2 14 is fixedly connected to the outer side of the cutting head 15. The two sliding seats 3 are provided with sliding holes 12 inside, and a socket 18 is provided above the sliding hole 12. One end of the cutting head 15 is fixedly connected to the sliding rod 16. A second clamping hole 17 is provided inside the sliding rod 16, and the outer side of the sliding rod 16 is slidably connected to the inner side of the sliding hole 12. When the two cutting heads 15 come into contact, one end of the special-shaped spring will be cut off. The elastic force of the second spring 14 can play a buffering effect to avoid causing too much damage to the cutting heads of the two cutting heads 15. When the strength of the material used is relatively high, a pin is inserted from the jack 18 and passed through the second clamping hole 17 to fix the position of the sliding rod 16.

[0025] Working principle: The processing disk 1 is installed on the main body of the spring forming equipment. The center of the processing disk 1 is used to extrude the steel wire. After the cooperation of the processing structures outside the multiple bases 2, the steel wire is made into the required spring shape. Finally, the two electric slide rails in relative positions are driven to make the two sliding seats 3 move towards each other. The contact of the two cutting heads 15 will cut off one end of the special-shaped spring. The second spring 14 can play a buffering effect to avoid causing too much damage to the blades of the two cutting heads 15. When the strength of the material used is high, the pin can be inserted from the socket 18 and passed through the second card hole 17. Inside, the position of the sliding rod 16 is fixed, so that the position of the cutting head 15 is fixed, and the cutting of the special-shaped spring will be more stable. When the processing head 9 needs to be replaced, the pull ring 8 can be pulled to pull the locking rod 5 out from the inside of the clamping hole 10, thereby releasing the fixation of the processing head 9. The processing head 9 can be easily taken out from the inside of the slide groove 11, which is more convenient than traditional bolt fastening. In addition, the processing head 9 can be inserted deep into the slide groove 11 so that the two clamping holes 10 are both engaged by the locking rod 5, so that the use length of the processing head 9 can be adjusted.
