[0002] Currently, in the continuous casting process of slabs, round steel coiled springs are required due to process requirements. In traditional processes, springs are often coiled manually, that is, the operator uses a jig to coil the springs. However, manual coiling often results in fluctuations in spring quality due to uneven force and differences in operating techniques, which affects the sealing and cooling functions of slab continuous casting at the start of pouring. In addition, manual spring coiling is inefficient and has high labor costs. Utility Model Content

[0003] Therefore, to solve the above problems, this utility model provides a spring winding device.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A spring winding apparatus, comprising: Workbench; The drive mechanism is mounted on the worktable; A control system is installed on the workbench and electrically connected to the drive mechanism to control the operation of the drive mechanism; A coiling shaft is connected to the output end of the drive mechanism; the end face of the coiling shaft away from the drive mechanism is radially provided with a slot for engaging round steel. The guide roller is rotatably parallel to and spaced apart from the rolling shaft, and the outer wall of the guide roller is provided with a spiral groove for guiding the round steel.

[0005] Optionally, the spiral groove is a constant pitch groove.

[0010] Optionally, the two ends of the guide roller are mounted on the worktable via bearing seats.

[0011] Optionally, the distance between the guide roller and the winding shaft can be adjusted.

[0012] The technical solution provided by this utility model has the following beneficial effects: 1. The control system controls the operation of the drive mechanism to ensure stable output, thereby enabling the coiling shaft to maintain a stable rotational speed when coiling round steel. Under the guidance of the guide rollers, the coiled springs have high consistency and stable quality, reducing dimensional deviations caused by human error. 2. The entire equipment can continuously and quickly roll springs without being limited by manual strength or speed, which can greatly improve the production rhythm. It is especially suitable for the needs of large-scale and continuous steelmaking production, avoiding the impact of slow manual spring rolling speed on the efficiency of slab continuous casting. In addition, it reduces reliance on manual labor and lowers long-term labor costs. At the same time, it avoids repetitive labor when manually rolling springs, improves the working conditions of workers, and reduces safety hazards caused by operator fatigue.

[0015] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] Reference Figure 1-5 This embodiment provides a spring coiling device, including a worktable 1, a drive mechanism 2, a control system 3, a coiling shaft 4, and guide rollers 5. The drive mechanism 2 and the control system 3 are both mounted on the worktable 1. The control system 3 is electrically connected to the drive mechanism 2 to control its operation; the control system 3 is an electrical control box. The output end of the drive mechanism 2 drives and connects to the coiling shaft 4. The end face of the coiling shaft 4 away from the drive mechanism 2 has radially formed grooves 41 for engaging round steel bars. The guide rollers 5 are rotatably parallel to and spaced apart from the coiling shaft 4, and their outer walls have spiral grooves 51 for guiding the round steel bars.

[0018] When coiling springs, one end of the round steel is clamped into the slot 41. The control system 3 controls the operation of the drive mechanism 2 to ensure stable output, thereby enabling the coiling shaft 4 to maintain a stable rotation speed when coiling the round steel. Under the guidance of the guide roller 5, the coiled springs have high consistency and stable quality, reducing dimensional deviations caused by human error. Furthermore, the equipment can continuously and quickly coil springs without being limited by human strength or speed, which can significantly improve the production rhythm. It is especially suitable for the needs of large-scale, continuous steelmaking production, avoiding the impact of slow manual spring coiling speed on the efficiency of slab continuous casting. In addition, it reduces reliance on manual labor and lowers long-term labor costs. At the same time, it avoids repetitive labor when manually coiling springs, improves workers' working conditions, and reduces safety hazards caused by operator fatigue.

[0019] In this embodiment, the spiral groove 51 is a constant pitch groove to improve the quality of the coiled spring.

[0020] In this embodiment, the drive mechanism 2 includes a drive motor 21 and a reducer 22. The drive motor 21 drives and connects to the reducer 22, and the reducer 22 drives and connects to the winding shaft 4. The drive motor 21 can be a low-power motor, such as a YE2-90S-4 motor with an output power of 1.1 kW. The reducer 22 can be a GW-E16 reducer with an output speed of 24 r / min. The output power of the motor 21 can be adjusted through the electronic control system to regulate the output speed of the reducer 22. Of course, other models of motors 21 and reducers 22 can also be used to suit the specifications of the springs to be wound. The reducer 22 is fixed to the worktable 1 by the mounting base 6.

[0021] In this embodiment, a drive flange 7 is provided at the output end of the reducer 22, and a transmission flange 8 is provided at the end of the winding shaft 4 near the reducer 22. The drive flange 7 and the transmission flange 8 are detachably fixedly connected. The winding shaft 4 and the reducer 22 are connected through the drive flange 7 and the transmission flange 8 to ensure the stability of the winding shaft 4 during rotation. The winding shaft 4 and the flange are connected by a key to achieve circumferential limiting.

[0022] In this embodiment, a frustum structure 81 is provided on the side of the transmission flange 8 away from the drive flange 7. That is, one end of the rolling shaft 4 is inserted into the frustum structure 81. The frustum structure 81 increases the connection length between the transmission flange 8 and the rolling shaft 4, thereby improving the connection stability between the two. In addition, the frustum structure 81 can play a mechanical limiting protection role.

[0023] In this embodiment, both ends of the guide roller 5 are mounted on the worktable 1 via bearing seats 9, ensuring smooth rotation of the guide roller 5. This allows rolling friction to occur primarily between the round steel and the guide roller 5 during the spring winding process, reducing wear on the round steel. In this embodiment, due to the length of the guide roller 5, the bearing seat 9 at one end of the guide roller 5 is fixed to the mounting base 6, and then mounted on the worktable 1. Alternatively, both bearing seats 9 at both ends of the guide roller 5 can be directly fixed to the worktable 1.

[0024] In other preferred embodiments, the distance between the guide roller 5 and the winding shaft 4 is adjustable. A strip-shaped mounting hole can be made on the worktable 1 along the axial direction perpendicular to the winding shaft 4, and the bearing seat 9 of the guide roller 5 is fixed to the strip-shaped mounting hole with bolts. When the diameters of the steel pipes to be rolled in the two batches are different, and the difference in diameter between the two batches is not significant, and the width of the groove 41 on the winding shaft 4 and the width of the spiral groove 51 on the guide roller 5 are both compatible, it is only necessary to slightly adjust the bearing seat 9 along the length direction of the strip-shaped mounting hole and then lock it to complete the adjustment of the distance between the guide roller 5 and the winding shaft 4, thereby rolling a spring that meets the requirements. If the diameter difference between the two batches of steel pipes is large, the corresponding winding shaft 4 and guide roller 5 can be replaced, and then the distance between them can be adjusted.

[0025] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
