This is an existing technology, so it will not be described here.

[0029] like Figure 1、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a locking structure is provided at the top of the base plate 20 for fixing the position of the pressure roller 23. The locking structure includes: a shift block 31, a top plate 32, a side block 33, a shift plate 35, a bolt 37 and a resistance plate 38. The shift block 31 is fixedly connected to the front wall end of the hydraulic cylinder 21, the top plate 32 is fixedly connected to the top of the shift block 31, the side blocks 33 are symmetrically fixedly connected to the two side walls of the shift block 31, the rear wall of the shaft frame 22 can be detachably connected to the front wall of the shaft frame 22, the shift plate 35 is movably connected to the top of the top plate 32, the bolt 37 is rotatably connected to the top of the top plate 32, the resistance plates 38 are symmetrically fixedly connected to the two side walls of the shift plate 35, and the bottom of the resistance plate 38 can contact the top of the base plate 20.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the wall surface of the bolt 37 can pass through the shift plate 35, the shift plate 35 is a rectangular plate, the bolt 37 can be threadedly connected to the wall surface of the shift plate 35 passed through, the contact plate 38 is also a rectangular plate, the symmetrical side blocks 33 are located between the symmetrical contact plates 38, and the side wall surface of the side block 33 on each side can contact the side wall surface of the contact plate 38. The locking structure also includes a bottom rod 40, a finger block 41, a side plate 24, a straight shaft 25, a connecting rod 26 and a clearance groove 39. The bottom rod 40 is fixedly connected to the bottom of each side block 33, the finger block 41 is fixedly connected to the front wall surface of the shift block 31, and the side plates 24 are symmetrical. It is fixedly connected to both sides of the top of the base plate 20, the straight shaft 25 is fixedly connected between the symmetrical side plates 24 on each side, the connecting rod 26 is fixedly connected to the side wall of the bottom rod 40 on each side, the clearance groove 39 is opened on the side wall of the contact plate 38, the side wall of the bottom rod 40 is rotatably connected with a roller, and the rollers on the symmetrical wall of the bottom rod 40 are located on both side walls of the shift rail 30. The straight shaft 25 is cylindrical, and one end of the connecting rod 26 can slide along the arc surface of the straight shaft 25. The clearance groove 39 can adapt to the thickness of the connecting rod 26. The finger block 41 is in the shape of an isosceles triangle block, and the bottom of the finger block 41 can contact the top of the shift rail 30;

[0031] During specific use, the base plate 20 is installed at a specified position on the spring machine. During processing, the material guide mechanism on the spring machine conveys the material to one side of the pressure roller 23, and then the material is processed into a spiral shape after being guided by the pressure roller 23. During processing, if the diameter of the material after forming needs to be adjusted, the hydraulic cylinder 21 will be started. After the hydraulic cylinder 21 is started, it will drive the shift block 31 to move in a straight line. When the shift block 31 moves, it pushes the shaft frame 22 to move synchronously along the top of the shift rail 30. When the shift block 31 moves, it controls the synchronous movement of the pressure roller 23. When the pressure roller 23 moves forward, the diameter of the material forming becomes smaller, and when the pressure roller 23 moves backward, the diameter of the material forming becomes larger. After adjusting the position of the pressure roller 23, the bolt 37 can be screwed. When the bolt 37 is screwed, it will be threaded with the shift plate 35. When the shift block 31 needs to be moved, the bolt 37 is tightened so that the resistance plate 38 no longer contacts the top of the base plate 20, and the movement of the shift block 31 can be controlled. When the shift block 31 moves, it will drive the side block 33 to move at the same time, and the side block 33 will drive the connecting rod 26 to move along the top of the straight shaft 25 at the same time.

[0032] To sum up, by setting up a locking structure, the position of the shift block 31 can be fixed without adjusting the position of the shift block 31. The locking structure drives the shift plate 35 and the resistance plate 38 to move downward synchronously by tightening the bolt 37, thereby forming a force that resists the substrate 20, thereby fixing the position of the shift block 31 at the top of the substrate 20 to prevent the shift block 31 from shifting during operation, resulting in a reduction in the error in the size of the spring produced. Therefore, compared with the existing technology, the probability of spring size error during use is lower in this solution.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the wall surface of the side block 33 is provided with a disassembly structure, which includes a connecting groove 34, a bullet box 42, a bullet groove 43, a bullet block 44 and a clamping rod 45. The connecting groove 34 is opened on the side wall surface of each side block 33, the bullet box 42 is fixedly connected to the top of each side block 33, the bullet groove 43 is opened on the front wall surface of each bullet box 42, the bullet block 44 is elastically connected in each bullet groove 43, and the clamping rod 45 is symmetrically fixedly connected on the rear wall surface of the shaft frame 22. The connecting groove 34 is a rectangular groove, and the bullet groove 43 is a T-shaped notch. The bullet block 44 is elastically connected in the bullet groove 43 by a spring. The bullet block 44 is a T-shaped block, and the front wall surface of the bullet block 44 is an arc surface. The bottom of the bullet block 44 is aligned with the top of the connecting groove 34, and the connecting groove 34 can adapt to the size of the clamping rod 45. The clamping rod 45 is an L-shaped rod. The symmetrical clamping rods 45 can be clamped in the symmetrical connecting grooves 34.

[0034] When the pressure roller 23 needs to be replaced or maintained, the shaft frame 22 is used to drive the clamping rod 45 to be lifted upward. At this time, the top of the clamping rod 45 contacts the curved surface of the front wall of the spring block 44, which pushes the spring block 44 toward the spring groove 43. After the clamping rod 45 is removed, the spring block 44 is pushed forward again by the spring in the spring groove 43. When installing the pressure roller 23, the clamping rod 45 is directly aligned with the top of the symmetrical spring block 44 and inserted into the connecting groove 34. At this time, the spring block 44 is pushed back into the spring groove 43 as the clamping rod 45 is inserted downward. After the clamping rod 45 is completely inserted into the connecting groove 34, the spring block 44 is extended out of the spring groove 43 again and contacts the top of the clamping rod 45.

[0035] In summary, by providing the disassembly structure, the pressure roller 23 can be removed from the device alone when needed, and when removing the pressure roller 23, only plugging and pulling movements are required to complete the disassembly and installation of the pressure roller 23.

[0036] Working principle: Install the base plate 20 at the designated position on the spring machine. During processing, the material guide mechanism on the spring machine conveys the material to one side of the pressure roller 23, and then the material is processed into a spiral shape after being guided by the pressure roller 23. During processing, if the diameter of the material after forming needs to be adjusted, the hydraulic cylinder 21 will be started. After the hydraulic cylinder 21 is started, it will drive the shift block 31 to move in a straight line. When the shift block 31 moves, it pushes the shaft frame 22 to move synchronously along the top of the shift rail 30. When the shift block 31 moves, it controls the synchronous movement of the pressure roller 23. When the pressure roller 23 moves forward, the diameter of the material forming becomes smaller, and when the pressure roller 23 moves backward, the diameter of the material forming becomes larger. After adjusting the position of the pressure roller 23, the bolt 37 can be tightened and the screw When the position of the shift block 31 needs to be moved, the bolt 37 is screwed so that the resistance plate 38 no longer contacts the top of the base plate 20, thereby controlling the movement of the shift block 31.
