Description

Technical Field

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

[0002] Spring processing refers to the process of making springs with specific elastic properties from metal or other elastic materials through a series of machining steps. These steps typically include material selection, cutting, bending, heat treatment to enhance mechanical properties, and surface treatment to improve corrosion resistance and wear resistance.

[0003] In the prior art, springs are often bent using bending equipment. The bending equipment mainly consists of a support frame, conveyor wheels, hydraulic cylinders, and limit posts. The conveyor wheels are provided in two sets, upper and lower, and grooves are provided on the conveyor wheels. When the conveyor wheels rotate on the support frame, the spring material passes through the two sets of conveyor wheels and moves along the grooves. The hydraulic cylinder controls the limit posts to hold the spring material, thereby causing the spring material to bend and form.

[0004] However, when the diameter of the spring material changes, the distance between the two sets of conveyor wheels cannot be adjusted, which prevents the two sets of conveyor wheels from supporting and conveying the spring material, thus affecting the applicability of the bending equipment. Utility Model Content

[0005] The purpose of this invention is to provide a bending device for spring processing, so as to solve the technical problem in the prior art where the spacing between the two sets of conveying wheels of the bending device cannot be adjusted, resulting in the conveying wheels being unable to hold the spring raw material for conveying.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A bending device for spring processing, comprising:

[0008] A support frame is provided with several sets of drive wheels equidistantly arranged on the side end along the length direction. A movable stop bar is fixedly connected to the end of the support frame near the drive wheels. Several sliding grooves are opened on the top of the support frame along the length direction. The drive wheels are rotatably connected to the support frame. Two sets of hydraulic cylinders are provided on the side end of the movable stop bar. The hydraulic cylinders are fixedly connected to the support frame. Limiting posts are fixedly connected to the side end of the hydraulic cylinders.

[0009] Driven wheel, the driven wheel is provided in several groups and is set on the top of the drive wheel, the driven wheel is fixedly connected to the side end of the driven wheel, the side end of the connecting shaft is rotatably connected to the slide block, the slide block is locked in the slide groove and slidably connected to the inner wall of the slide groove;

[0010] A connecting plate is fixedly connected to several sliding blocks at its side ends. Lifting rods are fixedly connected to both ends of the connecting plate, and a lifting device is fixedly connected to the top of each lifting rod. The lifting device is fixedly connected to the support frame.

[0011] As a further embodiment of this utility model: a detector is fixedly connected to the side end of the support frame, and a controller is fixedly connected to the end of the support frame away from the drive wheel. The detector is arranged between the two sets of drive wheels.

[0012] As a further embodiment of this utility model: a rotating shaft is fixedly connected to the side end of the drive wheel, a groove is axially provided on the drive wheel, a circular hole is provided through the support frame, the rotating shaft is rotatably connected to the inner wall of the circular hole, the side end of the rotating shaft is abutted and connected to the end of the support frame away from the drive wheel, a belt is sleeved and connected to the outer wall of the rotating shaft, the driven wheel and the drive wheel have the same shape, and the cross-section of the groove is "V" shaped.

[0013] As a further embodiment of this utility model: the belt sleeve is connected to a drive shaft, a servo motor is fixedly connected to the side end of the drive shaft, and the side end of the servo motor is fixedly connected to the support frame.

[0014] As a further embodiment of this utility model: an oil injection assembly is fixedly connected to the top of the slide block, the oil injection assembly is disposed on the slide block near the hydraulic cylinder, and a cutting blade is fixedly connected to the side end of the support frame, the cutting blade being located between the moving stop and the limiting post.

[0015] As a further embodiment of this utility model: the fuel injection assembly includes: a fuel injection pipe and a fuel tank, the bottom end of the fuel tank is fixedly connected to the slide block, and the side end of the fuel injection pipe is fixedly connected to the fuel tank.

[0016] The beneficial effects of this utility model are:

[0017] 1. When the spring material needs to be bent, it passes between the drive wheel and the driven wheel. The drive wheel rotates, moving the spring material. The driven wheel follows the movement of the spring material and rotates accordingly. Two sets of hydraulic cylinders control the limit posts to hold the spring material. The spring material is bent by the support of the limit posts. At the same time, the moving stop lever is driven by a cylinder using existing technology. The moving stop lever holds the bent spring and moves it away from the support frame, thereby achieving the effect of bending the spring material. When the size of the spring material changes, the hydraulic cylinder can control the limit posts to move, thus holding and bending spring materials of different sizes. The moving stop lever holds and moves the bent springs of different sizes.

[0018] 2. When the size of the spring material changes, the lifting device controls the movement of the lifting rod, thereby controlling the connecting plate to move up or down. The connecting plate drives the slide block to slide along the inner wall of the slide groove. The slide block drives the driven wheel to move vertically up or down through the connecting shaft, thus ensuring that the gap between the driven wheel and the driving wheel allows the spring material to pass through. This achieves the function of the driven wheel supporting spring materials of different sizes. The support between the slide block and the inner wall of the slide groove provides limiting support for the connecting shaft and the driven wheel. Attached Figure Description

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5 As shown, a bending device for spring processing includes: a support frame 1, a driven wheel 4, and a connecting plate 15.

[0028] A support frame 1 has several sets of drive wheels 2 evenly spaced along its length on one side. A movable stop bar 5 is fixedly connected to one end of the support frame 1 near the drive wheels 2. Several sliding grooves 14 are formed on the top of the support frame 1 along its length. The drive wheels 2 are rotatably connected to the support frame 1. Two sets of hydraulic cylinders 8 are provided on the side of the movable stop bar 5. The hydraulic cylinders 8 are fixedly connected to the support frame 1. Limiting posts 7 are fixedly connected to the side of the hydraulic cylinders 8. Several sets of driven wheels 4 are provided and are located on top of the drive wheels 2. A connecting shaft 12 is fixedly connected to the side of the driven wheels 4. A slide block 13 is rotatably connected to the side of the connecting shaft 12. The slide block 13 is engaged in the sliding groove 14 and slidably connected to the inner wall of the sliding groove 14. When the spring material needs to be bent, the spring material passes through the drive wheel 2. Between the driving wheel 2 and the driven wheel 4, the driving wheel 2 rotates, which drives the spring material to move. The driven wheel 4 rotates in tandem with the movement of the spring material. Two sets of hydraulic cylinders 8 control the limiting post 7 to hold the spring material. The spring material is bent by the support of the limiting post 7. At the same time, the moving stop 5 is driven by a cylinder of the prior art. The moving stop 5 holds the bent spring and moves it away from the support frame 1, thereby achieving the effect of bending the spring material. When the size of the spring material changes, the hydraulic cylinder 8 can control the limiting post 7 to move, so that spring materials of different sizes can be held and bent. The moving stop 5 holds the bent springs of different sizes and moves them.

[0029] The side end of the connecting plate 15 is fixedly connected to several slides 13. Lifting rods 22 are fixedly connected to both ends of the connecting plate 15. A lifting device 16 is fixedly connected to the top of the lifting rods 22. The lifting device 16 is fixedly connected to the support frame 1. When the size of the spring material changes, the lifting device 16 controls the movement of the lifting rods 22, thereby controlling the connecting plate 15 to move upward or downward. The connecting plate 15 drives the slides 13 to slide along the inner wall of the slide groove 14. The slides 13 drive the driven wheel 4 to move vertically upward or downward through the connecting shaft 12, thereby ensuring that the gap between the driven wheel 4 and the driving wheel 2 allows the spring material to pass through. This achieves the function of the driven wheel 4 supporting spring materials of different sizes. The support between the slides 13 and the inner wall of the slide groove 14 provides a limiting support for the connecting shaft 12 and the driven wheel 4.

[0030] In some specific implementations, a detector 3 is fixedly connected to the side of the support frame 1, and a controller 9 is fixedly connected to the end of the support frame 1 away from the drive wheel 2. The detector 3 is set between the two sets of drive wheels 2. When the spring material is conveyed through the drive wheel 2, the detector 3 can monitor the length of the spring material. The detector 3 transmits the monitoring signal to the controller 9, and the controller 9 controls the drive wheel 2 to move, so that springs of different lengths can be bent.

[0031] In some specific embodiments, a rotating shaft 19 is fixedly connected to the side end of the drive wheel 2. A groove 11 is axially formed on the drive wheel 2. A circular hole is formed through the support frame 1. The rotating shaft 19 is rotatably connected to the inner wall of the circular hole. The side end of the rotating shaft 19 abuts against the end of the support frame 1 away from the drive wheel 2. A belt 20 is sleeved on the outer wall of the rotating shaft 19. The driven wheel 4 has the same shape as the drive wheel 2. The groove 11 has a "V" shaped cross-section. A drive shaft 21 is sleeved on the belt 20. A servo motor 17 is fixedly connected to the side end of the drive shaft 21. The side end of the servo motor 17 is fixedly connected to the support frame 1. When the drive wheel 2 needs to rotate, the controller 9 controls the servo motor 17. When machine 17 is running, servo motor 17 controls drive shaft 21 to rotate, drive shaft 21 drives belt 20 to rotate, belt 20 drives rotating shaft 19 to rotate, rotating shaft 19 drives drive wheel 2 to rotate. Belt 20 realizes the transmission of driving force from servo motor 17 to several rotating shafts 19, thereby achieving the effect of several drive wheels 2 rotating simultaneously. The grooves 11 opened on drive wheel 2 and driven wheel 4 respectively support the bottom and top sides of spring material, preventing the spring from deviating or slipping when moving along the grooves 11, ensuring the accuracy of spring material movement, and thus ensuring the accuracy of bending spring material.

[0032] In some specific implementations, an oil spraying assembly is fixedly connected to the top of the slide 13. The oil spraying assembly is located on the slide 13 near the hydraulic cylinder 8. A cutting blade 6 is fixedly connected to the side of the support frame 1. The cutting blade 6 is located between the moving stop 5 and the limiting post 7. The oil spraying assembly includes an oil spraying pipe 10 and an oil reservoir 18. The bottom of the oil reservoir 18 is fixedly connected to the slide 13, and the side of the oil spraying pipe 10 is fixedly connected to the oil reservoir 18. In order to avoid the spring material generating noise due to excessive friction when bending, the oil spraying assembly operates before the spring material moves to the limiting post 7. The oil reservoir 18 sprays the stored lubricating oil through the oil spraying pipe 10 onto the groove 11 on the top of the driven wheel 4. When the driven wheel 4 rotates, it coats the spring material with lubricating oil. When the limiting post 7 supports and bends the spring material, the lubricating oil reduces the friction generated by the spring material, ensuring the resistance when the spring material is bent. When the spring material is bent, the cutting blade 6 operates and cuts the bent spring.

[0033] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
