The up and down movement of the gear plate drives the straightening plate to move synchronously. In this way, the steel wire body that was originally bent on the chassis surface will be gradually straightened under the reciprocating action of the straightening plate. In this way, when the steel wire body enters the twisting device, the resulting spring has higher quality and better specifications, avoiding quality defects such as uneven spring coil diameter and inconsistent pitch caused by the bending of the steel wire body.

[0013] 2. With the cleaning and drying components in place, considering that the surface of the newly formed spring may have lubricating oil or other stains, the workers can put the formed spring into the cleaning box and use the internal stirring frame to agitate and clean it. This can effectively remove oil and other impurities from the surface of the spring. Then, through the linkage of the fan and heating tube, the spring is quickly dried with hot air. This can quickly remove the residual moisture from the surface of the spring, allowing it to dry quickly, slowing down the rusting process, and extending the service life of the spring.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see the appendix Figure 1 - Appendix Figure 4 A spring processing wire twisting mechanism includes a worktable 1, a twisting device 2, and a wire body 3. A straightening assembly 4 is mounted on the top of the worktable 1. The straightening assembly 4 includes a straightening frame 401, a worm gear 404, a fixed frame 406, a base 409, and a guide block 410. The straightening frame 401 is connected to a worm gear 403 via a first motor 402. A connecting rod 405 is fixedly connected to the inner wall of the worm gear 404, with both ends of the connecting rod 405 rotatably connected to the inner wall of the straightening frame 401. A gear plate 407 is slidably connected to the inner wall of the fixed frame 406, and a straightening disc 408 is fixedly connected to the bottom of the gear plate 407. The straightening frame 401... 01 is fixedly installed on the top of the workbench 1. The first motor 402 is fixedly installed on the outer right side of the straightening frame 401. One end of the worm gear 403 is fixedly connected to the output shaft of the first motor 402, and the other end of the worm gear 403 is rotatably connected to the inner wall of the straightening frame 401. The worm gear 403 is meshed with the worm wheel 404, and the worm wheel 404 is meshed with the gear plate 407. The fixed frame 406 is fixedly installed on the inner wall of the straightening frame 401. The chassis 409 is fixedly installed on the top of the workbench 1 and located below the straightening plate 408. The guide block 410 is fixedly installed on the top of the workbench 1 and located on the left side of the straightening frame 401.

[0025] The top and bottom of the straightening frame 401 are provided with hollow grooves so that the gear plate 407 can slide smoothly up and down. The guide block 410 has a guide hole adapted to the size of the steel wire. The inner wall of the fixed frame 406 is provided with a sliding groove. The slider is fixedly connected to the surface of the gear plate 407 and slides in a sliding connection with the sliding groove.

[0026] Specifically, through the set straightening component 4, the staff starts the first motor 402, which drives the worm gear 403 to rotate. The worm wheel 404 rotates synchronously. The rotation of the worm wheel 404 drives the gear plate 407 to slide up and down along a predetermined trajectory inside the straightening frame 401. The up and down movement of the gear plate 407 causes the straightening plate 408 to move synchronously. In this way, the originally bent steel wire body 3 on the surface of the chassis 409 is gradually straightened under the reciprocating action of the straightening plate 408. When the steel wire body 3 enters the twisting device 2, the quality of the spring produced is higher and the specifications are better. This can avoid quality defects such as uneven spring coil diameter and inconsistent pitch caused by the bending of the steel wire body 3.

[0027] Example 2:

[0028] Please see the appendix Figure 1 Appendix Figure 5 -Appendix Figure 7Furthermore, based on Embodiment 1, a cleaning and drying assembly 5 is further provided on the top of the workbench 1 and behind the straightening assembly 4. The cleaning and drying assembly 5 includes a cleaning tank 501 and a support frame 505. The cleaning tank 501 is fixedly installed on the top right side of the workbench 1. A second motor 502 is fixedly connected to the outer wall of the cleaning tank 501. A drive rod 503 is fixedly connected to the output shaft of the second motor 502. One end of the drive rod 503 away from the second motor 502 is rotatably connected to the inner wall of the cleaning tank 501. An agitator frame 504 is fixedly connected to the circumferential surface of the drive rod 503. The support frame 505 is fixedly installed on the top of the workbench 1 and to the left side of the cleaning tank 501. A placement plate 506 is fixedly connected to the top of the support frame 505. A heating tube 507 is fixedly connected to the top of the support frame 505 and behind the placement plate 506. A fan 508 is fixedly connected to the top of the support frame 505 and behind the placement plate 506.

[0029] The top of the cleaning box 501 is fixedly connected to a water inlet pipe, which provides a channel for injecting clean water into the spring for subsequent cleaning. At the same time, the top of the placement plate 506 is designed with a groove that fits the shape of the spring, providing a stable placement space for the spring and facilitating subsequent hot air drying.

[0030] Specifically, the cleaning and drying assembly 5 takes into account that the surface of the newly formed spring may have lubricating oil or other stains. The operator can put the formed spring into the cleaning box 501 and perform agitation and cleaning through the stirring frame 504 inside. This can effectively remove oil and other impurities from the surface of the spring. Then, through the linkage of the fan 508 and the heating tube 507, the spring is quickly dried with hot air. This can quickly remove the residual moisture on the surface of the spring, so that it can quickly reach a dry state, slow down the rusting process, and extend the service life of the spring.

[0031] Working principle of this utility model: This utility model is a steel wire twisting mechanism for spring processing. First, the steel wire body 3, which is bent and to be processed, is placed on the chassis 409, with one end aligned with the guide hole of the guide block 410. The operator turns on the first motor 402, which drives the worm gear 403 to rotate. The worm gear 403 drives the worm wheel 404 to rotate synchronously. The worm wheel 404 rotates on the inner wall of the straightening frame 401 with the help of the connecting rod 405 fixed on the inner wall. The rotating worm wheel 404 meshes with the gear plate 407, driving the gear plate 407 to slide up and down along a predetermined trajectory in the groove on the inner wall of the fixed frame 406. The straightening plate 408, which is fixedly connected to the bottom of the gear plate 407, moves up and down reciprocally. Under the repeated squeezing action of the straightening plate 408, the originally bent steel wire body 3 on the chassis 409 is gradually straightened until the entire steel wire reaches a straight state, so that it can be processed into a high-quality product by the twisting device 2. To ensure the quality of springs is standardized and of the correct specifications, avoiding quality issues such as coil diameter and pitch caused by bent steel wire, the cleaning chamber 501 is cleaned by injecting clean water into the chamber through the water inlet pipe at the top. The freshly formed spring is then placed inside the cleaning chamber 501. The second motor 502 is started, driving the drive rod 503 to rotate on the inner wall of the cleaning chamber 501. The agitator frame 504, fixed on the circumference of the drive rod 503, rotates synchronously. The agitator frame 504 continuously agitates the cleaning water inside the cleaning chamber 501, causing the water flow to wash the surface of the spring, removing oil and impurities from the spring for effective cleaning. After the surface of the spring is clean, the spring is removed from the cleaning chamber 501 and placed in the groove of the placement plate 506 at the top of the support frame 505. At the same time, the fan 508 and the heating tube 507 are turned on. The heating tube 507 heats the air blown out by the fan 508, forming a hot airflow that quickly removes residual moisture from the surface of the spring until the spring is completely dry.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
