[0030] The present application is further described in detail below in conjunction with the accompanying drawings.

[0031] The present application discloses a spring machine, such as Figure 1 and Figure 2As shown, it includes a spring machine body 1, and a discharge port 13 for discharging wire is provided on the spring machine body 1. After the wire is discharged from the discharge port 13, it is processed by a processing tool on the spring machine body 1. Two parallel grooves are provided on one side of the spring machine body 1 close to the discharge port 13. The two grooves are radially arranged along the discharge port 13 of the spring machine body 1. Two sliding parts 12 are slidably connected to the grooves. A driving assembly 11 for driving the two sliding parts 12 to move is provided on the spring machine body 1. The driving assembly 11 can be driven by a cylinder or a motor screw. A cutting tool 32 and a supporting part 2 are respectively provided on the two sliding parts 12. A notch 21 for supporting the wire is provided on the supporting part 2. When the driving component 11 drives the supporting part 2 to move close to the wire, the inner wall of the notch 21 of the supporting part 2 abuts against the outer wall of the wire. The bottom end of the notch 21 is a semicircle that matches the outer wall of the wire to ensure the support stability of the wire. A cutting tool 32 is provided at one end of the cutting part 3 close to the wire. The cutting tool 32 can be inserted into the notch 21 of the supporting part 2. The wire in the notch 21 is cut off through the cooperation between the cutting tool 32 and the supporting part 2.

[0032] like Figure 2 As shown, the sliding part 12 is provided with a clamping assembly 4 for clamping the wire, and the clamping assembly 4 includes: two groups of clamping assemblies 4 including a bracket 41, a sliding rod 42, an abutting portion 44 and two compression springs 43 arranged on the sliding block, and the two brackets 41 are respectively abutted against the cutting part 3 and the side of the support part 2 away from the spring machine body 1. The qualified brackets 41 of the sliding part 12 are both provided with the same groove 5 on the side close to each other, and the cutting part 3 is provided with a first limit block 31 for plugging into the corresponding groove 5, and the outer wall of the first limit block 31 is in contact with the inner wall of the groove 5, so as to limit the position of the cutting tool 32 and enhance the installation stability of the cutting part 3. The support part 2 is provided with a first limit block 31 for plugging into the corresponding groove 5, and the outer wall of the first limit block 31 is in contact with the inner wall of the groove 5, so as to limit the position of the support part 2 and enhance the installation stability of the support part 2.

[0033] The bracket 41 is provided with through holes on one side close to the sliding part 12 and on the other side away from the sliding part 12. There are four through holes, and the inner wall of the through hole can be smooth or threaded. A fixing bolt 411 is provided in the through hole. The screw rod of the fixing bolt 411 passes through the through hole and is connected to the cutting part 3 or the supporting part 2 accordingly. The end of the fixing bolt 411 away from the through hole is threadedly connected to the sliding part 12. Tightening the fixing bolt 411, the cutting part 3 and the supporting part 2 are fixed by the mutual compression of the bracket 41 and the sliding part 12.

[0034] like Figure 2As shown, the sliding rod 42 is connected to the bracket 41, and the sliding direction of the sliding rod 42 is parallel to the sliding direction of the sliding part 12. The abutment part 44 is arranged at the end of the sliding rod 42 close to the wire. The two ends of the compression spring 43 are respectively arranged between the bracket 41 and the abutment part 44. The compression spring 43 applies a force toward the wire to the abutment part 44. When the two sliding parts 12 are close to each other, the compression spring 43 drives the abutment part 44 to abut against the outer wall of the wire. A V-shaped notch 441 is arranged on the side where the abutment parts 44 are close to each other to increase the friction between the abutment part 44 and the wire to prevent the wire from slipping. A fixed block 421 is arranged on the end of the sliding rod 42 away from the abutment part 44. When the abutment part 44 is away from the wire, the compression spring 43 drives the sliding rod 42 to move toward the side close to the wire, so that the fixed block 421 abuts against the bracket 41 to ensure the stability of the sliding rod 42.

[0035] The implementation principle of this embodiment is:

[0036] The driving assembly 11 drives the two sliding blocks to approach each other, and the abutting parts 44 approach each other on one side to abut against the wire. The sliding part 12 continues to move, so that the notch 21 of the support part 2 abuts against the inner wall of the wire. The cutting tool 32 on the cutting part 3 is inserted into the notch 21 of the support part 2 to cut the wire in the notch 21. The two abutting parts 44 fix the cut wire under the action of the compression spring 43.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
