Description
Technical Field
[0001] This utility model relates to the technical field of stainless steel bracket bending devices, specifically a stainless steel bracket bending device. Background Technology
[0002] A stainless steel bracket bending device is a mechanical device used for precise bending of stainless steel brackets. It is usually driven by hydraulic, CNC or manual means, equipped with high-strength molds, and bends stainless steel plates or tubes into specific angles by applying pressure. The high hardness and springback characteristics of stainless steel must be taken into account to ensure forming accuracy. It may also include lubrication and surface protection functions to avoid processing damage.
[0003] During the bending process of stainless steel brackets, metal debris is generated on the mold. This is mainly due to the high hardness and toughness of stainless steel, which causes the material edges to crack during bending. In addition, factors such as the intense friction between the mold and the sheet metal, the work hardening effect, and insufficient mold gaps or lubrication cause small, hard debris to adhere to the mold surface. If these debris are not cleaned in time, they may scratch subsequent workpieces or affect the processing accuracy. Currently, common cleaning methods rely on manual brushing, air gun blowing, or wiping, but these are inefficient and difficult to completely remove debris from mold grooves and dead corners, affecting production efficiency. Therefore, we propose a stainless steel bracket bending device. Utility Model Content

[0006] The effects achieved by the above components are as follows: by setting up a cleaning structure, it is easy to clean the debris adhering to the surface of the lower and upper molds, avoid residual debris from scratching the stainless steel surface when bending the bracket, reduce rework and scrap rate, and thus prevent mold wear, scratches or local corrosion, and reduce replacement frequency.
[0007] Preferably, the surface of the sponge block has a through hole, and a round rod is inserted into the inner wall of the through hole. Limiting plates are fixedly connected to both ends of the round rod.
[0008] The effect achieved by the above components is that two limiting plates are installed on both sides of the sponge block with the help of round rods. The limiting plates limit the deformation of the sponge block, so that the sponge block can be reset after deformation.
[0009] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the fixing plate, respectively.
[0010] The effect achieved by the above components is that the pin is inserted into the round hole by the force of the spring contraction. The spring improves the stability of the pin when it is removed and inserted into the round hole, and prevents the pin from coming out of the round hole due to shaking.
[0011] Preferably, two guide rods are fixedly connected to the surface of the rectangular plate, and both guide rods slide through the slider.
[0012] The effect achieved by the above components is that the slider will be driven by the rectangular plate to drive the guide rod through the slider, and the guide rod will limit the position of the rectangular plate and prevent the fixed block from shaking inside the slider.
[0013] Preferably, the surface of the slider has two rectangular grooves, and the inner wall of the rectangular grooves is rotatably connected to a plurality of rotating wheels, which slide against the inner wall of the grooves.
[0014] The effect achieved by the above components is as follows: the movement of the slider will cause the rotating wheel to slide along the inner wall of the groove. The rotating wheel will rotate in the groove with the help of the slider movement. The rotating wheel reduces the friction when the slider slides in the groove, thereby facilitating the movement of the slider and thus the movement of the sponge block.
[0015] Preferably, a rectangular block is fixedly connected to one side of the lower mold, and a placement groove is formed on the surface of the rectangular block. The size of the placement groove is adapted to the size of the groove, and a magnetic block is fixedly connected to the surface of the rectangular block.
[0016] The effects achieved by the above components are as follows: the rectangular block facilitates the placement of the cleaning structure, thereby avoiding the need to remove the cleaning structure from the bending machine during bending; the magnetic block facilitates the temporary restriction of the slider position, thereby facilitating the restriction of the cleaning structure.
[0017] Preferably, a support arm is fixedly connected to the surface of the rectangular block, and an oil can is fixedly connected to the end of the support arm away from the rectangular block.
[0018] The effect achieved by the above components is as follows: when lubricating oil is added to the oil can, the lubricating oil in the oil can will gradually drip onto the surface of the sponge block, and the lubricating oil will gradually soak into the sponge block. The lubricating oil in the sponge block will wipe the surface of the lower mold and the upper mold, so that lubricating oil can be applied while cleaning the lower mold and the upper mold.

[0027] 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.
[0028] Please see Figure 1-2 This utility model provides a technical solution: a stainless steel bracket bending device, including a bending machine 1, a lower mold 2 and an upper mold 3 mounted on the surface of the bending machine 1, a cleaning structure 4 on the surface of the lower mold 2, the cleaning structure 4 including a groove 401, the groove 401 being formed on one side of the lower mold 2, a slider 402 slidably connected to the inner wall of the groove 401, a fixing plate 403 fixedly connected to the surface of the slider 402, a pin 404 slidably passing through the surface of the fixing plate 403, and a pin 404 inserted into the surface of the slider 402. There is a fixing block 405, and a round hole 406 is opened on the surface of the fixing block 405. The size of the pin 404 is adapted to the size of the round hole 406. A rectangular plate 407 is fixedly connected to one side of the fixing block 405. A sponge block 408 is glued to the surface of the rectangular plate 407. By setting the cleaning structure 4, it is easy to clean the debris adhering to the surface of the lower mold 2 and the upper mold 3, so as to avoid the residual debris scratching the stainless steel surface when bending the bracket, reducing rework and scrap rate, and thus preventing mold wear, scratches or local corrosion, and reducing replacement frequency.
[0029] Reference Figure 3 and Figure 4 and Figure 5As shown in this embodiment: a through hole 409 is formed on the surface of the sponge block 408, and a round rod 410 is inserted into the inner wall of the through hole 409. Limiting plates 411 are fixedly connected to both ends of the round rod 410. Two limiting plates 411 are installed on both sides of the sponge block 408 via the round rod 410. The limiting plates 411 limit the deformation of the sponge block 408, thus facilitating its return to its original position after deformation. A spring 412 is fitted onto the arc surface of the pin 404. The two ends of the spring 412 are fixedly connected to the pin 404 and the fixing plate 403, respectively. The pin 404 is inserted into the round hole 406 by the contraction force of the spring 412. The spring 412 improves the stability of the pin when it is removed from the round hole 406, preventing the pin 404 from coming out of the round hole 406 due to shaking. Two guide rods 413 are fixedly connected to the surface of the rectangular plate 407. Both guide rods 413 slide through the slider 402. The slider 402 is driven by the rectangular plate 407 to pass through the guide rods 413. The guide rods 413 limit the position of the rectangular plate 407 and prevent the fixed block 405 from shaking inside the slider 402. Two rectangular grooves 414 are formed on the surface of the slider 402. Several rotating wheels 415 are rotatably connected to the inner wall of the rectangular grooves 414. The rotating wheels 415 slide against the inner wall of the grooves 401. The movement of the slider 402 will drive the rotating wheels 415 to slide along the inner wall of the grooves 401. The rotating wheels 415 will rotate inside the grooves 401 with the help of the movement of the slider 402. The rotating wheels 415 reduce the friction when the slider 402 slides in the grooves 401, thereby facilitating the movement of the slider 402 and, consequently, the movement of the sponge block 408. A rectangular block 416 is fixedly connected to one side of the lower mold 2. A placement groove 417 is provided on the surface of the rectangular block 416. The size of the placement groove 417 is adapted to the size of the groove 401. A magnetic block 420 is fixedly connected to the surface of the rectangular block 416. The rectangular block 416 facilitates the placement of the cleaning structure 4, thereby avoiding the need to remove the cleaning structure 4 from the bending machine 1 during bending. The magnetic block 420 facilitates the temporary restriction of the position of the slider 402, thereby facilitating the restriction of the cleaning structure 4. A support arm 418 is fixedly connected to the surface of the rectangular block 416. An oil can 419 is fixedly connected to the end of the support arm 418 away from the rectangular block 416. When lubricating oil is added to the oil can 419, the lubricating oil in the oil can 419 will gradually drip onto the surface of the sponge block 408. The lubricating oil will gradually soak into the sponge block 408. The lubricating oil in the sponge block 408 will wipe the surface of the lower mold 2 and the upper mold 3, so that lubricating oil can be applied while cleaning the lower mold 2 and the upper mold 3. The lubricating oil forms a protective film between the lower mold 2 and the upper mold 3 and the stainless steel plate, reducing direct contact friction and extending the service life of the mold.
[0030] Working principle: When cleaning is required for the lower mold 2 and upper mold 3, first pull the pin 404. The pin 404 moves and slides within the fixed block 405. The movement of the pin 404 stretches the spring 412. Then, the fixed block 405 is inserted into the slider 402. The slider 402, with the help of the rectangular plate 407, drives the guide rod 413 through the slider 402. The guide rod 413 restricts the position of the rectangular plate 407, preventing the fixed block 405 from wobbling within the slider 402. Release the pin 404, and the pin 404, with the help of the spring 412, inserts into the round hole 406, thus restricting the position of the fixed block 405. This restricts the position of the rectangular plate 407. Then, a sponge block 408 is adhered to the surface of the rectangular plate 407, thus mounting the sponge block 408 onto the surface of the slider 402. Two limiting plates 411 are installed on both sides of the sponge block 408 via round rods 410. The limiting plates 411 limit the deformation of the sponge block 408, allowing it to return to its original position after deformation. Then, the slider 402 is pulled, causing it to slide within the groove 401. The movement of the slider 402 drives the rotating wheel 415 to slide along the inner wall of the groove 401. The rotating wheel 415 rotates within the groove 401 with the help of the slider 402, thus reducing the slippage. The friction of block 402 sliding in groove 401 facilitates the movement of slider 402, and consequently the movement of sponge block 408. When slider 402 slides into the placement groove 417 on the surface of rectangular block 416, the magnetic block 420 on the surface of rectangular block 416, being an iron block, uses magnetic force to limit the position of slider 402. Then, lubricating oil is added to oil can 419. The lubricating oil in oil can 419 gradually drips onto the surface of sponge block 408, gradually seeping into it. When sponge block 408 is fully soaked, the upper mold 3 is moved closer to the lower mold 2. As the upper mold 3 moves to the appropriate position, it moves closer to the lower mold 2 and the upper mold 3. Once the sponge block 408 is in the appropriate position, it will wrap around the upper mold 3 and adhere to the surface of the lower mold 2. As the sponge block 408 continues to move, it will wipe away debris from the surfaces of the upper mold 3 and the lower mold 2. At the same time, the lubricating oil inside the sponge block 408 will be wiped onto the surfaces of the lower mold 2 and the upper mold 3, making it easier to apply lubricating oil to the lower mold 2 and the upper mold 3. The lubricating oil forms a protective film between the lower mold 2 and the upper mold 3 and the stainless steel plate, reducing direct contact friction and extending the service life of the mold.
