[0002] In the arch device of the snake spring machine, the problem with traditional technology is that it is impossible to achieve precise control of the spring length. The traditional technology uses fixed-length plum blossom teeth, and the number of arches corresponding to springs of different lengths is different. Therefore, in traditional technology, it is impossible to accurately adjust the length of each spring, resulting in the length of the produced spring being unstable and inaccurate, which may affect the quality and use of the spring, and may even cause safety problems. Utility Model Content
[0003] In order to make up for the deficiencies of the prior art, the utility model provides a precision arch device for a serpentine spring machine.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A precision arch device for a serpentine spring machine comprises a vertical support plate, a pair of bevel teeth and a plum blossom tooth. A side support plate is provided on a horizontal plate connected to the vertical support plate, and an inclined mounting plate for mounting a worm gear reducer is fixed on the side support plate; the pair of bevel teeth comprises a main transmission bevel tooth and a driven bevel tooth meshing with the main transmission bevel tooth, and the driven bevel tooth is locked and fixed on the reducer input shaft by a locking screw, and the reducer input shaft is transmission-connected to the input end of the worm gear reducer through a plum blossom coupling; the plum blossom tooth is transmission-connected to the reducer output shaft at the output end of the worm gear reducer, and the plum blossom tooth is arranged corresponding to the gap surrounded by the width adjustment plates on both sides of the spring support plate.
[0006] The worm gear reducer adopts a 1:10 worm gear reducer, that is, the output speed of the worm gear reducer is one tenth of the input speed;
[0007] By transmitting power to the bevel gear, the reducer input shaft allows the 1:10 worm gear reducer to move, and the reducer output shaft drives the plum blossom teeth to rotate, so that the plum blossom teeth rotate outward one arch for each arch of the snake spring machine (for example, the current spring requires 10 arches of 500mm long), and the spring is only 495mm long at this time, so loosen the locking screw on the driven bevel gear and let the reducer input shaft rotate outward 1 / 3 of a circle. Then, when the reducer input shaft is rotated, the plum blossom teeth will rotate backward. After adjustment, reset the driven bevel gear and lock the locking screw; because the number of arches from the die head to the plum blossom teeth is certain, by fine-tuning the bevel gear to control the length between the die head and the plum blossom teeth, the length of the punched spring can be more accurate and stable, thereby achieving the purpose of speeding up the overall machine operation.
[0008] Preferably, a reinforcing plate A is connected between the inclined mounting plate and the side support plate, and a reinforcing plate B is connected between the horizontal plate and the vertical support plate.

[0017] Compared with the prior art, the technical effects and advantages of the utility model are: the precision arch device of the serpentine spring machine realizes precise fine-tuning of the spring length by using a worm gear reducer and a bevel gear system. This allows precise adjustment during the spring manufacturing process when the spring length deviates slightly to ensure that the length of the spring meets strict manufacturing standards. Through the mechanized adjustment process, the time and frequency of manual adjustment are reduced, and production efficiency is improved. The automated fine-tuning system can respond and adjust quickly, thereby speeding up the entire production process.
[0018] By precisely controlling the spring length, quality problems caused by improper human operation are reduced, and the quality and consistency of the product are improved. This helps to reduce the scrap rate and increase the market for the product. The device can quickly adapt to the production needs of springs of different specifications and lengths, thereby improving production flexibility. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] The following is combined with Figure 1-3 Provide further details of this application;
[0028] The embodiment of the present application discloses a precision arch device of a serpentine spring machine, comprising a vertical support plate 1, a pair of bevel teeth and a plum blossom tooth 11. A side support plate 3 is provided on a horizontal plate 2 connected to the vertical support plate 1, and an inclined mounting plate 5 for mounting a worm gear reducer 4 is fixed on the side support plate 3; the pair of bevel teeth comprises a main transmission bevel tooth 6 and a driven bevel tooth 7 meshing with the main transmission bevel tooth 6, and the driven bevel tooth 7 is locked and fixed on the reducer input shaft 9 by a locking screw 8, and the reducer input shaft 9 is transmission-connected to the input end of the worm gear reducer 4 through a plum blossom coupling 10; the plum blossom tooth 11 is transmission-connected to the reducer output shaft 12 at the output end of the worm gear reducer 4, and the plum blossom tooth 11 is arranged corresponding to the gap surrounded by the width adjustment plates 14 on both sides of the spring lifting plate 13.
[0029] The working principle of the precision arch device of the snake spring machine is as follows:
[0030] First, the input shaft of the worm gear reducer 4 is connected to the input end of the worm gear reducer 4 through the plum blossom coupling 10. The worm gear reducer 4 adopts a 1:10 worm gear reducer 4, that is, the output speed of the worm gear reducer 4 is one tenth of the input speed.
[0031] Then, power is transmitted through a pair of bevel gears (pair of bevel gears), in which the main transmission bevel gear 6 is connected to the reducer input shaft 9, and the driven bevel gear 7 is fixed to the reducer input shaft 9 through the locking screw 8. When the reducer input shaft 9 rotates, the driven bevel gear 7 will be driven to rotate.
[0032] Then, the plum blossom teeth 11 are connected in transmission with the reducer output shaft 12 at the output end of the worm gear reducer 4. When the reducer output shaft 12 rotates, the plum blossom teeth 11 rotate accordingly.
[0033] During the process of the spring machine 23, the plum blossom tooth 11 will rotate outward by one arch. For example, if the spring needs to be 10 arches and 500mm long, but the spring is only 495mm long at this time, fine adjustment can be achieved by loosening the locking screw 8 on the driven bevel tooth 7 and rotating the reducer input shaft 9 outward by 1 / 3 of a turn. In this way, when the reducer input shaft 9 rotates, the plum blossom tooth 11 will rotate backward, thereby adjusting the length of the spring.
[0034] Finally, the driven bevel gear 7 is reset and the locking screw 8 is locked. Since the number of arches from the die head to the plum blossom tooth 11 is certain, the length between the die head and the plum blossom tooth 11 is controlled by fine-tuning the bevel gear, so that the length of the punched spring is more accurate and stable.
[0035] By fine-tuning the bevel gear to control the length between the die head and the plum blossom teeth 11, the length of the punched spring can be made more accurate and stable. This is very important for the production of springs that require high consistency, which can improve product quality and reduce the rate of defective products. By adjusting the input shaft position of the worm gear reducer 4, the spring length can be fine-tuned. This adjustability makes process adjustment more convenient and flexible, and can quickly adapt to the needs of springs of different specifications and lengths. The precision arch device can increase the operating speed of the entire snake spring machine 23, thereby speeding up production speed and output. Manual adjustments and wasted time are reduced, and production efficiency and profits are increased. Due to the precise control and automatic adjustment of the spring length, errors and variables caused by manual operation are reduced. This can improve product consistency and stability and reduce quality problems caused by human factors.
[0036] In summary, the precision arch device of the serpentine spring machine can improve the quality and efficiency of spring manufacturing and reduce manual operation errors. The whole process improves the overall operating speed of the serpentine spring machine 23, while also ensuring the length accuracy and stability of the spring.
[0037] A reinforcing plate A15 is connected between the inclined mounting plate 5 and the side support plate 3, a reinforcing plate B16 is connected between the horizontal plate 2 and the vertical support plate 1, the spring support plate 13 is fixed on the U-shaped support plate 17 on one side of the horizontal plate 2, and a reinforcing plate C18 is connected between the U-shaped support plate 17 and the horizontal plate 2.
[0038] The addition of reinforcing plates A15, B, and C improves the structural stability of the entire device. The reinforcing plates provide additional support at the joints between the inclined mounting plate 5 and the side support plate 3, between the horizontal plate 2 and the vertical support plate 1, and between the U-shaped support plate 17 and the horizontal plate 2, reducing vibration and displacement caused by the operation of the machine and ensuring the long-term stable operation of the device.
[0039] The use of reinforcing plates enhances the reliability of the connections between the various components. In the process of power transmission and mechanical vibration, the reinforcing plates help to disperse stress and prevent loose connections caused by vibration, thereby improving the reliability and service life of the entire device. Through the reasonable design of the reinforcing plates, the spatial layout of the device can be optimized, making the entire device more compact and saving space. This is crucial for the installation and maintenance of the equipment, helping to reduce the occupied space at the production site and improve the cleanliness of the production environment. The reinforcing plate C18 fixes the spring lifting plate 13 on the U-shaped support plate 17, which not only ensures the stability of the spring lifting plate 13, but also protects the lifting plate and the spring thereon from external shocks and vibrations, thereby ensuring the stability of the spring quality. The use of reinforcing plates can improve the durability of the entire device. When subjected to repeated loads and extreme conditions, the reinforcing plates help to resist fatigue damage, extend the service life of the equipment, and reduce maintenance costs.
[0040] A support plate 19 is provided at the bottom of the spring lifting plate 13, a locking screw 21 is connected to the through hole 20 provided on the support plate 19 through a thread, a waist hole 22 is provided on the spring lifting plate 13 for the locking screw 21 to penetrate, and the locking screw 21 is used to lock the plum blossom tooth 11 when the machine is stopped, ensuring the alignment between the plum blossom tooth 11 and the spring lifting plate 13. This can effectively avoid errors and misalignments in the position of the plum blossom tooth 11, and ensure the precise operation and working stability of the device.
[0041] The main transmission bevel gear 6 is rotatably mounted on the chassis 24 of the spring serpentine machine 23, and the chassis 24 is also equipped with a bearing seat A25 that cooperates with the reducer input shaft 9 to rotate, and the inclined mounting plate 5 is equipped with a bearing seat B26 that cooperates with the reducer input shaft 9 to rotate, and the horizontal plate 2 is fixed with a support 28, and the support 28 is equipped with a bearing seat C27 that cooperates with the reducer output shaft 12 to rotate. The design of the main transmission bevel gear 6, the bearing seat and the support 28 enables good rotational coordination between the reducer input shaft 9, the output shaft and the spring serpentine machine precision arch device, and improves the stability and accuracy of the entire device. This helps to ensure the precise rotation of the plum blossom teeth 11 and the precise forming of the spring.
[0042] The precision arch device of the serpentine spring machine also includes a square eccentric block 29 driven by a motor in a chassis 24 and rotating on the chassis 24, a connecting rod 31 connecting the square eccentric block 29 and a joint bearing 30 on the chassis 24, an upper die head 32 arranged on the joint bearing 30, a lower die head 33 rotating on the machine base platform and cooperating with the upper die head 32 to pull the serpentine spring, and a rear swing tail device 34.
[0043] The rear tail swing device 34 includes a tail swing shaft 35 rotatably arranged on the machine base platform, a tail swing support 37 located below and sleeved on the tail swing shaft 35 and locked by a screw rod A36, and a rear tail swing 38 located above. A U-shaped block 39 is provided at the bottom of the rear tail swing 38, and the rear tail swing 38 is locked with the tail swing support 37 by screw rods B40 threadedly connected on both sides of the U-shaped block 39; the rear tail swing 38 is adjusted toward the bending direction of the snake spring by loosening the screw rods A36 and B40 on the rear tail swing 38.
[0044] Power is transmitted through the square eccentric block 29 in the belly of the machine (i.e., on the chassis 24), so that the connecting rod 31 and the joint bearing 30 move to make the tail swing shaft 35 on the rear tail swing device 34 swing left and right. The upper end of the tail swing shaft 35 is the rear tail swing 38. When the snake spring produced by the machine is not straight (the snake spring bends to the front or back of the machine), loosen the screw rod A36 on the rear tail swing 38, adjust the screw rod B40 threadedly connected on both sides of the U-shaped block 39, and adjust the rear tail swing 38 a small amount in the bending direction of the snake spring, and then lock the screw rod B40 and the screw rod A36. This facilitates the precise adjustment of the snake spring when the length direction of the snake spring deviates, and the adjustment is convenient.
[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
