Description

Technical Field

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

[0002] Stainless steel springs are mechanical parts made by stamping, utilizing the elasticity and toughness of stainless steel. Their main function is to deform under pressure and return to their original shape after the pressure is removed, thereby providing continuous contact force, cushioning, or positioning.

[0003] Existing technology disclosure number CN218925779U discloses a metal spring bending device, belonging to the field of metal spring technology. It includes a base assembly and a lower die component. The lower die component is bolted to the top side of the base assembly, and an upper die bending mechanism is bolted to the upper corner of the base assembly. The lower die component includes a bolt base. After the raw material is placed on the lower die, slider plates are set on both ends of the raw material for limiting and fixing. When the upper die bending mechanism performs stamping and bending, when the upper and lower dies are aligned, the slider plates can adaptively adjust according to the changes in the product structure formed by the material under the limiting of the telescopic spring rod, so as to ensure that the product is finally formed into the required shape during processing. Due to the clamping and limiting of the telescopic spring rod, it is not easy for the product to be misaligned during the bending process.

[0004] While the above-mentioned methods have certain advantages in terms of clamping and limiting, they still have certain drawbacks.

[0005] 1. After each processing is completed, the equipment needs to be paused, and the bent spring pieces need to be manually removed before they can be bent and used again, which is quite troublesome.

[0006] 2. Furthermore, repeatedly starting and stopping the equipment can easily reduce its lifespan and prevent continuous operation. Utility Model Content

[0028] Example 1:

[0029] Please see Figures 1-6This utility model discloses a stainless steel spring bending device, comprising a driving device 1, a bending device 2 fixedly connected to the front end of the driving device 1, a motor 3 fixedly connected to the upper end of the driving device 1, an elliptical cylinder 4 rotatably connected to the inner bottom end of the bending device 2, with the upper end of the elliptical cylinder 4 fixedly connected to the output end of the motor 3, two connecting plates 5 rotatably connected to the left and right sides of the inner bottom end of the bending device 2, a tension spring 6 fixedly connected to the left side between the two connecting plates 5 via a connecting column, a roller 7 rotatably connected to the left side of the connecting plate 5, the roller 7 being in contact with the outer side of the elliptical cylinder 4, and a limit post 8 fixedly connected to the right side of the upper end of the connecting plate 5. A U-shaped plate 9 is slidably connected to the inner side of the bending device 2. A fixing block 10 is fixedly connected to the upper end face of the U-shaped plate 9. Two inclined grooves 11 are formed on the upper end face of the U-shaped plate 9, and the limiting post 8 is inserted into the inner side of the inclined groove 11 and slidably connected to each other. Two triangular plates 12 are fixedly connected to the upper end face of the U-shaped plate 9. An inclined tooth plate 13 is fixedly connected to the upper inclined surface of the triangular plate 12. A sliding groove 14 is provided on the upper end face of the bending device 2, and the fixing block 10 is slidably connected to the sliding groove 14. A first module 15 is slidably connected to the upper end face of the bending device 2, and the lower end face of the first module 15 is fixedly connected to the fixing block 10. A second module 16 is fixedly connected to the upper end face of the bending device 2. The second module 16 is front of... Limiting right-angle plates 17 are fixedly connected to the left and right sides of the end face. The rear end face of the bending device 2 has a movable slot 18, and the connecting plate 5 is inserted into the movable slot 18. A reserved opening 19 is opened at the angle between the upper end face of the bending device 2 and the left and right end faces of the inner side of the second module 16. A spring plate 20 is rotatably connected to the inside of the reserved opening 19. A column 21 is fixedly connected to the upper half of the front end face of the spring plate 20. A helical gear 22 is inserted into and rotatably connected to the column 21. A torsion spring 23 is provided on the upper half of the rear end face of the spring plate 20. A slot 24 is provided on the inner side wall of the helical gear 22. A locking block 25 is inserted into and slidably connected to the outer side of the column 21. A spring is provided at the sliding connection between the locking block 25 and the column 21. When the elliptical cylinder 4 rotates continuously, the roller 7 and connecting plate 5 drive the U-shaped plate 9 to reciprocate, thereby causing the helical tooth plate 13 to periodically mesh and separate from the helical gear 22, realizing the swing and automatic reset of the spring plate 20. The opposing surfaces of the first module 15 and the second module 16 together form the cavity for bending the spring piece. The limiting right angle plate 17 is used to position the inserted spring piece. The cooperation between the locking block 25 and the bayonet 24 allows the helical gear 22 to be selectively fixedly connected to the column 21 or to rotate freely. The inclination angle of the inclined groove 11 determines the conversion ratio between the lateral displacement of the limiting column 8 and the longitudinal displacement of the U-shaped plate 9.

[0030] The working principle of a stainless steel spring bending device based on Embodiment 1 is as follows:

[0031] First, when using the device, connect it to an external power source to provide the necessary power. Then, place the spring piece that needs to be bent inside the right-angle plate 17 at the front end of the second module 16 for limiting. Then, turn on the motor 3 to drive the elliptical cylinder 4 to rotate intermittently, which will open one side of the connecting plate 5 through the roller 7. At the same time, the tension spring 6 will be stretched. The corresponding connecting plate 5 will rotate, which will drive the limiting column 8 to move and squeeze the inside of the inclined groove 11. At the same time, it will push the U-shaped plate 9 to move and drive the first module 15 to the second module 16 through the fixing block 10. During the process, the bending can be achieved by contacting the spring piece and squeezing and deforming it.

[0032] Secondly, when the U-shaped plate 9 moves, it will drive the triangular plate 12 to mesh with the helical gear 22 through the helical tooth plate 13, and at the same time drive the helical gear 22 to rotate freely. When the bending is completed, as the elliptical cylinder 4 rotates and no longer opens the connecting plate 5, the tension spring 6 rebounds and pulls the connecting plate 5 to reset on one side. Conversely, the U-shaped plate 9 moves and resets, and the fixing block 10 drives the first module 15 to disengage from the second module 16. At the same time, the helical tooth plate 13 moves in the opposite direction, and the locking block 25 engages with the locking slot 24, driving the helical gear 22 to rotate. At the same time, the spring plate 20 moves and the torsion spring 23 stores force. When the helical tooth plate 13 moves and disengages from the helical gear 22, the torsion spring 23 rebounds and drives the spring plate 20 to move and contact the spring piece, automatically popping the spring piece out from the inside of the second module 16 without manual removal. This can be repeated to achieve continuous feeding and bending.

[0033] This utility model provides an improved stainless steel spring bending device. In use, the spring is placed inside the limiting right-angle plate 17 on the front end of the second module 16 for limiting. At the same time, the motor 3 is turned on, and the elliptical cylinder 4 rotates intermittently, which in turn opens the connecting plate 5 through the roller 7. The tension spring 6 stretches and rebounds, and the U-shaped plate 9 moves, driving the first module 15 to move, thus squeezing and bending the spring. At the same time, when the U-shaped plate 9 moves, the engagement and disengagement of the helical tooth plate 13 and the helical gear 22 cause the torsion spring 23 to rebound, driving the spring plate 20 to move and contact the spring, automatically popping the spring out from the inside of the second module 16 without manual removal. This process can be repeated to achieve continuous feeding and bending.

All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings.
