[0025] Working principle: In this embodiment, the present invention also proposes a method for using a spring winding device for spring processing, comprising the following steps: Step 1, firstly, electrically connect each electrical appliance in the device to the external control device through a wire, then open the sealing plug 28 and fill the cooling liquid cavity of the winding roller 9 with cooling liquid, so that the winding roller 9 can improve its own heat dissipation effect; then reinstall the sealing plug 28, and then stably install the winding roller 9 on the suspended rotation of the spline cylinder 6 through the cooperation of the flange and the spline block 27, so that the winding roller 9 is in a coaxial position with the spline cylinder 6 and the spline shaft 21; then, according to the density of the spring to be wound, adjust the horizontal angle of the roller seat 18 on the top of the sliding seat 17, and lock and fix the roller seat 18 after the horizontal angle adjustment through the cooperation of the locking bolt and the fixing bolt to avoid deflection when guiding the steel bar, and then place one end of the heated steel bar on the guide roller 19; Step 2, then start the electric push cylinder 20 to push the lifting seat 16 up, and the lifted lifting seat 16 can make the steel bar placed on the guide roller 19 close to the bottom of the winding roller 9, and then install the positioning plate 15 at the outer end of the winding roller 9, and insert the limiting bolt 39 into the positioning hole at the end of the winding roller 9, and make the magnetic block 40 on the limiting bolt 39 and the magnet sheet in the positioning hole magnetically fixed, so as to realize the installation and fixation of the positioning plate 15. When the positioning plate 15 is installed, the steel bar can be pressed and fitted to the bottom of the winding roller 9 through the rib pressing seat 38; Step three, then the worm 25 is driven to rotate by turning the adjusting hand wheel, and the meshing of the worm 25 and the worm wheel 26 drives the bidirectional screw 22 to rotate, and the rotating bidirectional screw 22 facilitates the two adjusting seats 23 to move closer to each other, thereby driving the positioning pressure wheel 24 on the adjusting seat 23 to move closer to the winding roller 9, which is convenient for supporting and fixing winding rollers 9 with different diameters, thereby improving the application range of the device; then the bidirectional lead screw 11 is driven to rotate by starting the servo motor 10, and the two movable seats 12 are driven to move relative to each other by the bidirectional lead screw 11, thereby driving the positioning frame 13 and the supporting frame 14 to move toward the winding roller 9, thereby making the positioning pressure wheel 24 abut against the outer wall of the winding roller 9; Step 4, then start the reduction motor 8 to drive the spline shaft 21 to rotate, and the rotating spline shaft 21 drives the spline cylinder 6 to rotate, and the rotating spline cylinder 6 drives the winding roller 9 to rotate, and the rotating winding roller 9 is used to wind the steel bar pressed on the shaft body by the rib pressing seat 38, and the hydraulic cylinder 7 is started to push the movable plate 5 to move toward the protection box 4, and the movable plate 5 drives the rotating spline cylinder 6 to move, and then drives the rotating winding roller 9 to move, so that the steel bar is evenly wound on the winding roller 9, and in the process of spring winding, the bulletproof wheel 36 is set, which can play a role of pressing the steel bar wound on the winding roller 9 during the winding process, and can avoid the whole steel bar from tilting or swinging when it is wound to the tail end, and can play a role of secondary negative pressure limit on the tail end of the steel bar winding; Step 5, when the positioning frame 13 descends, the pusher assembly and the anti-collapse assembly will be synchronously lifted and lowered with the positioning frame 13. When the pusher assembly descends, the arc strip at the bottom of the lifting seat 30 can be abutted against the surface of the winding roller 9, and under the action of the stabilizing rod 31 and the return spring 32, the arc strip at the bottom of the lifting seat 30 can be prevented from rigidly colliding with the shaft body, and it can be suitable for winding rollers 9 of different thicknesses; at the same time, before using the bulletproof wheel 36, the adjusting screw 35 is driven to rotate forward and reverse by rotating the hand wheel disk, so as to drive the rectangular plate to adjust the elastic coefficient of the spring telescopic seat 37, thereby increasing the force of the bulletproof wheel 36 pressing on the steel bar, and also preventing the bulletproof wheel 36 from rigidly colliding with the steel bar during the descent, thereby improving the protective effect during spring winding, and avoiding the occurrence of surface pits on the surface of the wound steel bar due to rigid impact; Step six, after completing the winding of the spring, remove the positioning plate 15 from the winding roller 9, and drive the movable plate 5 and the spline cylinder 6 to return to their positions through the hydraulic cylinder 7, and then drive the winding roller 9 to return to their positions. During the return process, the arc-shaped bar at the bottom end of the lifting seat 30 is still in contact with the winding roller 9, and the wound spring will be blocked by the arc-shaped bar and the lifting seat 30. In the process of the winding roller 9 moving back, the pushed material assembly automatically pushes the wound spring off the shaft body, and there is no need to manually pull the spring off the shaft body, which improves the convenience and efficiency of automatic unloading of the spring after winding is completed. Finally, after the spring winding is completed, each mechanism can be reset.
