Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically a bending device for spring production and processing. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Made of elastic material, it deforms under external force and returns to its original shape after the force is removed. It is also called a "spring". They are generally made of spring steel. Springs come in a wide variety of types; according to shape, they mainly include helical springs, spiral springs, leaf springs, and irregularly shaped springs.

[0003] According to a public notice (Announcement No.: CN217290229U) regarding a bending and forming equipment for automobile spring production, the aforementioned application describes a cylindrical structure with through holes at both ends and a second circular hole on one side. A circular groove is formed on one side of the inner wall of the second circular hole. A second motor is fixed to one side of the cylinder, and a drive shaft connected to the second motor extends into the second circular hole. A second rotating shaft is fixed to one side of the drive shaft, and a gear is fixed to one side of the second rotating shaft. The upper and lower ends of the gear mesh with a rack. An arc-shaped plate is fixed to the rear end of the rack meshed with the upper end of the gear, and an arc-shaped plate is fixed to the front end of the rack meshed with the lower end of the gear. When a spring needs to be produced, the control switch box is operated to start the second motor, causing the gear to rotate and move the rack to the appropriate positions. Then, the first motor is started to rotate the cylinder to produce the spring. After the spring is produced, the second motor is started to bring the arc-shaped plate into contact with the cylinder. This achieves the effect of producing springs of different sizes as needed, while also facilitating the removal of the springs.

[0004] Because the pitch of automotive springs directly affects their elastic coefficient, load-bearing capacity, and compression stroke. For example, the pitch of passenger car suspension springs differs significantly from that of truck suspension springs, and the pitch requirements also vary in different parts of the same vehicle model. The aforementioned equipment can only produce fixed pitch springs, which cannot meet the diverse needs of different vehicle models and functional components for springs. This limits the application range of the equipment and prevents it from processing and producing springs with different pitches according to requirements. Summary of the Invention

[0017] like Figures 1-4As shown, this utility model provides a technical solution: a bending device for spring production and processing, including a base 1, a side plate 2 fixedly connected to the surface of the base 1, a turntable 3 fixedly connected to one side of the side plate 2, and a motor 31 fixedly connected to the other side of the side plate 2. The output shaft of the motor 31 passes through and is rotatably connected to the side wall of the side plate 2. The output shaft of the motor 31 is fixedly connected to the side wall of the turntable 3. An expansion shaft 32 is provided on the side wall of the turntable 3. Spring material is wound on the surface of the expansion shaft 32. The expansion shaft 32 adapts to springs of different diameters by expanding / contracting. The output shaft of the motor 31 drives the turntable 3 and the expansion shaft 32 to rotate, providing rotational power for spring winding. A support plate 4 is fixedly connected to the side wall of the side plate 2. A pitch adjustment component 5 is provided on the surface of the support plate 4. The pitch adjustment component 5 includes a sleeve 51, which passes through and is rotatably connected to the surface of the support plate 4. The sleeve 51 serves as the carrier of the pitch adjustment component 5, and its rotation can drive the angle change of subsequent components. Two sets of rings 52 are fixedly connected to the outer wall of the sleeve 51. One set of rings 52 has multiple arrayed slots 53 on its side wall, which are used to engage with the limiting component 8 to fix the angle of the sleeve 51. A telescopic rod 54 is fixedly connected to the bottom of the other set of rings 52. A disc 55 is fixedly connected to the bottom end of the telescopic rod 54. A lead screw 56 is fixedly connected to the surface of the disc 55, passing through and threadedly connected to the sleeve 51. A handwheel 57 is fixedly connected to the top end of the lead screw 56. The telescopic rod 54 connects the lower ring 52 to the disc 55. When the handwheel 57 is rotated, the lead screw 56 drives the disc 55 to rise and fall axially, and the telescopic rod 54 extends and retracts synchronously, ensuring the stability of the disc 55. This allows the disc 55 to approach the surface of the expansion shaft 32, and the sleeve 51 is rotated to adjust the tilt angle of the clamping component 6, changing the tilt angle of the raw material winding and achieving pitch adjustment.

[0018] A clamping assembly 6 is provided at the bottom of the disc 55. The clamping assembly 6 includes a slide groove 61, which is formed on the bottom surface of the disc 55. Two sets of symmetrically arranged moving blocks 62 are slidably connected inside the slide groove 61. The two sets of moving blocks 62 are threadedly connected by a bidirectional threaded rod 63, which passes through and is rotatably connected to the side wall of the disc 55. One end of the bidirectional threaded rod 63 is rotatably connected to the side wall of the slide groove 61, and the other end of the bidirectional threaded rod 63 is fixedly connected to a rotating wheel 64. A mounting frame 65 is fixedly connected to the bottom surface of the moving blocks 62, and a roller 66 is rotatably connected to the inner wall of the mounting frame 65. The rotation of the rotating wheel 64 can adjust the distance between the two sets of moving blocks 62 to accommodate spring materials of different diameters. The material passes between the two sets of rollers 66. During winding, the rollers 66 rotate synchronously with the material, reducing friction while ensuring that the material moves along a preset trajectory and ensuring uniform pitch.

[0019] The surface of the support plate 4 has a groove 7, and a limiting component 8 is provided inside the groove 7. The limiting component 8 includes a pressure plate 81, which is slidably connected to the side wall of the pressure plate 81 and slidably connected inside the groove 7. The side wall of the pressure plate 81 has a through hole, and a guide rod 82 is slidably connected in the through hole. The guide rod 82 is fixedly connected to the inner wall of the groove 7. One side of the pressure plate 81 is elastically connected to the inner wall of the groove 7 by a return spring 83, and the other side of the pressure plate 81 is fixedly connected to an insert block 84, which is inserted into the slot 53. The pressure plate 81 is located in the groove 7 of the support plate 4 and is guided by the guide rod 82. The return spring 83 causes the insert block 84 on one side of the pressure plate 81 to be tightly inserted into the slot 53, thereby fixing the angle of the sleeve 51. During adjustment, the pressure plate 81 is manually moved to disengage the insert block 84 from the slot 53. After rotating the sleeve 51 to the target angle, it is released. The return spring 83 pushes the insert block 84 back into the slot 53 to complete the limit and ensure the stability of the structure after the pitch is adjusted.

[0020] In this invention, one end of the spring steel wire to be processed is fixed to the expansion shaft 32, and the other end of the material is passed through the gap between the two sets of rollers 66 in the clamping assembly 6. The rotating wheel 64 is rotated, and the bidirectional threaded rod 63 rotates accordingly, causing the two sets of moving blocks 62 to move closer or further apart in the slide groove 61 until the two sets of rollers 66 are tightly attached to the surface of the material. This ensures effective guidance of the material without hindering its smooth movement due to excessive clamping, thus completing the initial positioning of the material.

[0021] Manually pull the pressure plate 81 of the limiting component 8, causing it to slide away from the ring 52 along the guide rod 82. The return spring 83 is compressed, and the insert block 84 disengages from the slot 53 of the ring 52, releasing the angle lock on the sleeve 51. According to the target spring pitch requirement, turn the handwheel 57. The screw 56 and the sleeve 51 are threadedly driven, causing the disc 55 to rise and fall axially. The telescopic rod 54 extends and retracts synchronously to adapt to the height change of the disc 55, ensuring that the disc 55 always remains horizontal, so that the clamping component 6 is close to the surface of the expansion shaft 32. At the same time, rotate the sleeve 51 to adjust the overall tilt angle of the disc 55 and the bottom clamping component 6. By changing the guide angle of the roller 66 to the raw material, the tilt degree of the raw material winding onto the expansion shaft 32 is indirectly controlled. When the angle is adjusted to match the target pitch, the pressure plate 81 is released, the reset spring 83 releases its elastic force, pushes the pressure plate 81 to reset, and the insert block 84 is re-engaged into the corresponding slot 53 of the ring 52, firmly locking the angle of the sleeve 51, thus completing the setting of the pitch parameter.

[0022] After the parameters are set, motor 31 is started. The output shaft of motor 31 drives turntable 3 and expansion shaft 32 to rotate at a constant speed. Under the rotational driving force of expansion shaft 32, the raw material moves continuously towards expansion shaft 32 along the guide trajectory of roller 66 of clamping assembly 6, and gradually winds into a helical spring as expansion shaft 32 rotates. During the winding process, roller 66 rotates synchronously with the movement of raw material, which reduces friction loss between raw material and roller 66, and ensures that the pitch of each turn of spring is uniform and consistent with the preset parameters through stable guiding action.

[0023] When the spring is processed to the preset length, turn off the motor 31 and release the roller 66 of the clamping assembly 6 to remove the formed spring from the machine. If springs with different pitches need to be processed, simply repeat the above pitch adjustment steps. The parameters can be switched by adjusting the angle of the sleeve 51 and the height of the disc 55. The operation is convenient and can ensure processing accuracy, effectively meeting the diverse needs of spring production.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
