Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, and in particular relates to an anti-springback guide structure for a furniture processing bending machine. Background Technology

[0002] Traditional furniture bending machines face a thorny problem during operation: the springback phenomenon after bending the board. During the bending process, due to the internal stress, the board will inevitably spring back to a certain extent after the bending pressure is released, causing the bending angle to deviate from the design requirements. The springback problem not only reduces the yield rate of furniture production and increases production costs, but may also affect the overall structural stability and appearance quality of the furniture. Therefore, it is necessary to perform anti-bending treatment on the bent furniture.

[0003] However, during long-term use, the existing anti-rebound guide structure is prone to deformation of the buckle due to the frequent impact and vibration generated when the sheet metal is bent. This causes the clamping roller assembly to loosen, making it difficult to accurately clamp and stably guide and prevent the sheet metal from rebounding. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-rebound guide structure for a furniture bending machine. By setting a snap-fit ​​mechanism, the existing anti-rebound guide structure is solved. During long-term use, the snap-fit ​​is prone to deformation due to the frequent impact and vibration generated when the anti-rebound structure is subjected to the bending of the board. This causes the clamping roller assembly to loosen, making it difficult to accurately snap and stably guide and prevent the board from rebounding.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an anti-springback guide structure for a furniture processing bending machine, including a bending machine body, on which a snap-fit ​​mechanism and an anti-springback mechanism are provided;

[0007] The top of the bending machine body is fixedly connected to several L-shaped support rods, and a support plate is fixedly connected to the side of the several L-shaped support rods away from the bending machine body. The locking mechanism includes a slide rod that passes through the support plate. The slide rod is slidably connected to the support plate. A handle is fixedly connected to the top of the slide rod. A circular baffle is fixedly connected to the outer wall of the slide rod. The anti-rebound mechanism includes a connecting plate fixedly connected to the bottom of the slide rod. Two support frames are fixedly connected to the bottom of the connecting plate.

[0008] Furthermore, a circular baffle is fixedly connected to the outer wall of the slide rod one, a trapezoidal slider is slidably connected to the outer wall of the slide rod one, a trapezoidal limiting block is fixedly connected to the outer wall of the slide rod one, and two rectangular support plates are fixedly connected to the bottom of the bending machine body.

[0009] Furthermore, each of the two rectangular support plates has a cylinder extending through it, and the two cylinders are fixedly connected to the two rectangular support plates respectively. Each of the two cylinders has a sliding rod extending through it, and the two sliding rods are slidably connected to the two cylinders respectively.

[0010] Furthermore, each of the two slide rods has a slider fixedly connected to its outer wall, and the outer walls of the two sliders are slidably connected to the two cylinders respectively. Each of the two slide rods has a spring sleeved on its outer wall, with the sides of the two springs that are close to each other being fixedly connected to the two sliders respectively, and the sides of the two springs that are far apart from each other being fixedly connected to the two cylinders respectively.

[0011] Furthermore, a circular limiting plate is fixedly connected to the side of each of the two sliding rods that are far apart from each other, and a trapezoidal locking block is fixedly connected to the side of each of the two sliding rods that are close to each other. Both trapezoidal locking blocks are adapted to trapezoidal limiting blocks, and both trapezoidal locking blocks are adapted to trapezoidal sliders.

[0012] Furthermore, a rotating shaft is rotatably connected to the inner wall of each of the two support frames, and a circular roller is fixedly connected to the outer wall of each of the two rotating shafts.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a snap-fit ​​mechanism, after bending, the handle can be raised, causing it to move the trapezoidal slider upwards via slide rod one. When the trapezoidal limit block encounters the two trapezoidal locking blocks, due to the continuous upward movement of the trapezoidal slider, the two trapezoidal locking blocks will move away from each other. Under the action of slide rod two and the slider, the two springs will be compressed until the trapezoidal slider is above the two trapezoidal locking blocks. At this point, release the handle, and the top of the trapezoidal slider will contact the trapezoidal limit block. Then, press slide rod one downwards, and the connecting plate will move downwards under the action of the trapezoidal slider. After use, pull slide rod one upwards again to position the trapezoidal limit block above the two trapezoidal locking blocks. When the two trapezoidal blocks are in use, they will lock the connecting plate on the slide rod through the trapezoidal limiting block under the elastic force of the spring. This allows the connection to be maintained better when subjected to the impact and vibration of the plate bending, reducing the possibility of loosening and preventing connection failure due to external forces. This ensures the reliability of stable guidance and anti-rebound operation of the plate. When it is necessary to lock the connecting plate, the elastic force of the spring allows the trapezoidal blocks to lock tightly in place with the trapezoidal limiting block. Furthermore, when the plate bending generates impact and vibration, the spring can absorb some of the energy, reducing the impact on the entire structure, lowering the risk of component damage, and extending the service life of the structure.

[0015] 2. By setting up an anti-rebound mechanism, when the connecting plate moves downward, the two support frames also move downward, thereby driving the roller on the rotating shaft to move downward. When the roller touches the bent board, it will guide the board to prevent rebound, making the contact area between the roller and the board relatively small and rolling friction. When guiding the board to prevent rebound, the force on the board surface can be more uniform. Compared with other possible guiding methods, such as planar contact guidance, the roller can avoid excessive local pressure that could cause damage or uneven deformation of the board surface.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1-5 As shown, this utility model is an anti-rebound guide structure for a furniture processing bending machine, including a bending machine body 1, a snap-fit ​​mechanism 2 and an anti-rebound mechanism 3 on the bending machine body 1, a plurality of L-shaped support rods 101 fixedly connected to the top of the bending machine body 1, and a support plate 102 fixedly connected to the side of the plurality of L-shaped support rods 101 away from the bending machine body 1.

[0027] The locking mechanism 2 includes a slide rod 211 that passes through the support plate 102. The slide rod 211 is slidably connected to the support plate 102. A handle 212 is fixedly connected to the top of the slide rod 211. A circular baffle 213 and a circular baffle 214 are fixedly connected to the outer wall of the slide rod 211. A trapezoidal slider 215 is slidably connected to the outer wall of the slide rod 211. A trapezoidal limiting block 216 is fixedly connected to the outer wall of the slide rod 211. Two rectangular blocks are fixedly connected to the bottom of the bending machine body 1. Two rectangular support plates 217 are provided, each with a cylinder 218 extending through it. The two cylinders 218 are fixedly connected to the two rectangular support plates 217. Each cylinder 218 has a sliding rod 219 extending through it, and the two sliding rods 219 are slidably connected to the two cylinders 218. A slider 220 is fixedly connected to the outer wall of each sliding rod 219, and the outer wall of each slider 220 is slidably connected to the two cylinders 218. A spring 221 is fitted onto the outer wall of each sliding rod 219, and the two springs 221 interact with each other. The two springs 221 are fixedly connected to two sliders 220 on their adjacent sides, and to two cylinders 218 on their respective distant sides. Circular limiting plates 222 are fixedly connected to the distant sides of the two sliding rods 219, and trapezoidal locking blocks 223 are fixedly connected to the adjacent sides of the two sliding rods 219. Both trapezoidal locking blocks 223 are adapted to trapezoidal limiting blocks 216, and both trapezoidal locking blocks 223 are adapted to trapezoidal sliders 215. By setting the locking mechanism 2, the impact force of the plate bending is effectively controlled. During vibration, it can better maintain the connection state, reduce the possibility of loosening, and is less likely to fail due to external forces, thus ensuring the reliability of stable guidance and anti-rebound operation of the plate. When it is necessary to lock the connecting plate 311, the elastic force of the spring 221 can make the trapezoidal locking block 223 tightly lock the trapezoidal limiting block 216. Furthermore, when the plate is bent and generates impact force and vibration, the spring 221 can absorb some energy, reduce the impact on the entire structure, reduce the risk of component damage, and extend the service life of the structure.

[0028] The anti-rebound mechanism 3 includes a connecting plate 311 fixedly connected to the bottom of the slide bar 211. Two support frames 312 are fixedly connected to the bottom of the connecting plate 311. A rotating shaft 313 is rotatably connected to the inner wall of each of the two support frames 312. A circular roller 314 is fixedly connected to the outer wall of each of the two rotating shafts 313. By setting the anti-rebound mechanism 3, the contact area between the circular roller 314 and the board is relatively small and rolling friction occurs. When guiding the board to prevent rebound, the force on the board surface can be more uniform. Compared with other possible guiding methods, such as planar contact guiding, the circular roller 314 can avoid the situation where excessive local pressure causes damage or uneven deformation of the board surface.

[0029] A specific application of this embodiment is as follows: In use, first prepare the sheet material to be bent and place it on the bending machine body 1. Start the bending machine body 1 to bend it. After bending, lift the handle 212, causing it to move the trapezoidal slider 215 upwards via the first slide rod 211. When the trapezoidal limit block 216 encounters the two trapezoidal locking blocks 223, due to the continuous upward movement of the trapezoidal slider 215, the two trapezoidal locking blocks 223 will move away from each other. Under the action of the second slide rod 219 and the slider 220, the two springs 221 will be in a compressed state until the trapezoidal slider 215 is above the two trapezoidal locking blocks 223. At this point, release the handle 212, and the top of the trapezoidal slider 215 will... When the slide bar 211 contacts the trapezoidal limiting block 216, it is pressed down. The connecting plate 311 will move downward under the action of the trapezoidal slider 215. After use, the slide bar 211 is pulled up so that the trapezoidal limiting block 216 is above the two trapezoidal locking blocks 223. At this time, the two trapezoidal locking blocks 223 will lock the connecting plate 311 on the slide bar 211 through the trapezoidal limiting block 216 under the action of the spring force of the spring 221. When the connecting plate 311 moves downward, the two support frames 312 will also move downward, thereby driving the roller 314 on the rotating shaft 313 to move downward. When the roller 314 touches the bent plate, it will guide the plate to prevent springback.
