Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and more specifically, to an adjustable-angle bending machine. Background Technology

[0002] Bending machines are indispensable key equipment in metal sheet processing, widely used in machinery manufacturing, automotive industry, aerospace, and architectural decoration, among other fields. They can precisely bend metal sheets of varying thicknesses and materials according to preset angles and shapes to meet production needs. However, with increasingly diverse processing requirements, to further improve production flexibility and enable rapid bending at different angles, bending machines are often designed with adjustable bending angles. However, existing adjustable-angle bending machines do not address the cleaning of the bending platform, which can easily lead to debris generated during bending negatively impacting subsequent bending quality.

[0003] To address the aforementioned issues, Chinese patent CN221497079U discloses an adjustable-angle bending machine, comprising a bending table, a support column, a bending mechanism, and a cleaning mechanism. The bending mechanism enables precise and rapid bending of workpieces, while the cleaning mechanism ensures timely cleaning of the bending platform, preventing debris from affecting subsequent bending operations. However, during bending, the direct connection between the miniature electric actuator and the bending plate makes plate replacement difficult. Furthermore, with increasing bending time, the bending plate gradually wears down due to frequent contact with the metal sheet. Failure to disassemble and replace the bending plate ultimately leads to inaccurate bending angles and a decline in workpiece surface quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adjustable angle bending machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An adjustable-angle bending machine includes a worktable, an angle adjustment mechanism at the top of the worktable, a locking mechanism symmetrically arranged at the top of the angle adjustment mechanism, a bending mechanism between the two locking mechanisms, and a pressing mechanism above the bending mechanism.

[0008] Furthermore, in order to achieve bending at different angles, the bidirectional screw can be rotated under the rotation of the motor output shaft, thereby driving the two sets of moving blocks to move, thus changing the included angle between the bending plates, so as to quickly and accurately change the bending angle, thereby improving the production efficiency and flexibility of the bending machine. The angle adjustment mechanism includes a limit frame 1 set at the top of the worktable, a bidirectional screw is inserted inside the limit frame 1, a motor is set at one end of the bidirectional screw, and moving blocks that mesh with it are symmetrically arranged on the outside of the bidirectional screw.

[0009] Furthermore, to facilitate the replacement of the bending plate, when the connecting column is inserted into the slot, it presses against the locking rod. Under the action of the spring, the connecting column and the locking rod are locked together. When the bending plate needs to be disassembled and replaced, the locking rod is pulled towards the pressing mechanism to pull it out of the connecting column, allowing the operator to remove and replace the bending plate. This facilitates the maintenance of the bending machine and extends its service life. The locking mechanism includes a moving plate at the top of the moving block, and the top of the moving plate has a slot that cooperates with the bending mechanism. Both ends of the slot are equipped with locking rods that penetrate the moving plate. The locking rods and the moving plate are connected by a spring.

[0010] Furthermore, to facilitate the operator's observation of the bending angle, the scale plate can move with the movement of the second connecting column under the mutual clamping action of the connecting groove and the first protrusion. This allows the operator to easily observe the bending angle based on the position of the bending plate, ensuring the operator's accurate grasp of the bending angle. The bending mechanism includes a first connecting column located inside the slot and cooperating with the locking rod. A bending plate is located on the outer middle of the first connecting column. The two sets of bending plates are connected by the second connecting column. Both ends of the second connecting column are provided with connecting grooves. A first protrusion is provided inside the connecting groove and cooperating with it. A follower block is provided on one side of the first protrusion. A limit frame two is provided on the outer side of the follower block and cooperating with it. A spring two is provided at the top of the follower block. The two sets of spring two are connected by a base plate. A scale plate cooperating with the bending plate is provided on the side of the follower block away from the angle adjustment mechanism. The cross-section of the connecting groove is a trapezoidal structure.

[0011] Furthermore, to improve the stability and precision of the bending process and prevent the workpiece from springing back after bending, the workpiece is pressed down and bent under the extension of the electric telescopic rod. After bending, the workpiece surface is slowly released under the contraction of the electric telescopic rod, the elasticity of the spring three, and the squeezing action of the second protrusion, thereby effectively preventing the workpiece from springing back and ensuring the production quality of the workpiece. The pressing mechanism includes a pressure block set above the bending mechanism. Several spring threes are set on both sides of the pressure block. A connecting plate connected to the pressure block is set on the side of the spring threes away from the pressure block. Several second protrusions are set on the side of the connecting plate away from the pressure block. An electric telescopic rod is set at the top of the pressure block. The electric telescopic rod is connected to the worktable through a connecting frame. Several spring threes are evenly arranged and distributed in a rectangle on one side of the pressure block.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated arrangement of an angle adjustment mechanism, a locking mechanism, a bending mechanism, and a pressing mechanism, can not only quickly and accurately change and observe the included angle between the bending plates, improving the production efficiency and flexibility of the bending machine, but also prevent the workpiece from springing back after bending, ensuring the production quality of the workpiece. In addition, it also realizes the quick installation and disassembly of the bending plates, simplifying the maintenance process of the bending machine and extending the service life of the bending machine.

[0014] 2. Through the locking mechanism, the connecting column and the locking rod can be locked together by the extension and retraction of the spring. When the bending plate needs to be disassembled and replaced, the locking rod is pulled towards the pressing mechanism to pull it out of the interior of the connecting column, so that the operator can remove and replace the bending plate, which facilitates the maintenance of the bending machine and extends the service life of the bending machine.

[0015] 3. The pressing mechanism can be used to press down and bend the workpiece under the extension of the electric telescopic rod. After bending, the pressure on the workpiece surface can be slowly released under the contraction of the electric telescopic rod, the elasticity of the spring three, and the squeezing action of the second protrusion, thereby effectively preventing the workpiece from springing back and ensuring the production quality of the workpiece.

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the present invention, an adjustable-angle bending machine is provided.

[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-7 As shown, the adjustable angle bending machine according to an embodiment of the present utility model includes a worktable 1, an angle adjustment mechanism 2 is provided at the top of the worktable 1, a locking mechanism 3 is symmetrically provided at the top of the angle adjustment mechanism 2, a bending mechanism 4 is provided between the two sets of locking mechanisms 3, and a pressing mechanism 5 is provided above the bending mechanism 4.

[0029] With the help of the above-mentioned technical solution of this utility model, the utility model, through the coordinated arrangement of angle adjustment mechanism 2, locking mechanism 3, bending mechanism 4 and pressing mechanism 5, can not only quickly and accurately change and observe the included angle between bending plates 402, improving the production efficiency and flexibility of bending machine, but also avoid the springback of workpiece after bending, ensuring the production quality of workpiece. In addition, it also realizes the quick installation and disassembly of bending plate 402, simplifies the maintenance process of bending machine, and extends the service life of bending machine.

[0030] In one embodiment, the angle adjustment mechanism 2 includes a limiting frame 201 disposed at the top of the workbench 1. A bidirectional screw 202 is inserted inside the limiting frame 201. A motor 203 is disposed at one end of the bidirectional screw 202. Moving blocks 204 that mesh with the bidirectional screw 202 are symmetrically disposed on the outer side of the bidirectional screw 202. Under the rotation of the output shaft of the motor 203, the bidirectional screw 202 can rotate, thereby driving the two sets of moving blocks 204 to move, thereby changing the included angle between the bending plates 402, so as to quickly and accurately change the bending angle, thereby improving the production efficiency and flexibility of the bending machine.

[0031] The working principle of the angle adjustment mechanism 2: By starting the motor 203, the bidirectional screw 202 rotates under the action of the output shaft of the motor 203, thereby driving the two sets of moving blocks 204 to move, thus changing the included angle between the bending plates 402, so as to quickly and accurately change the bending angle, thereby improving the production efficiency and flexibility of the bending machine.

[0032] In one embodiment, the locking mechanism 3 includes a movable plate 301 disposed at the top of the movable block 204, and the top of the movable plate 301 is provided with a slot 302 that cooperates with the bending mechanism 4. Both ends of the slot 302 are provided with locking rods 303 that penetrate the movable plate 301. The locking rods 303 and the movable plate 301 are connected by a spring 304. Under the action of the spring 304, the connecting column 401 and the locking rods 303 can be locked together. When the bending plate 402 needs to be disassembled and replaced, the locking rods 303 are pulled towards the pressing mechanism 5 to pull the locking rods 303 out of the interior of the connecting column 401, so that the operator can remove and replace the bending plate 402, which facilitates the maintenance of the bending machine and extends the service life of the bending machine.

[0033] In addition, it should be noted that in order to ensure that the connecting post 401 and the engaging rod 303 engage with each other, the two ends of the connecting post 401 are provided with through holes that cooperate with the engaging rod 303. These through holes are not shown in the figure.

[0034] The working principle of the locking mechanism 3: When the connecting column 401 is inserted into the slot 302, the connecting column 401 presses against the locking rod 303. Under the action of the spring 304, the connecting column 401 and the locking rod 303 are locked together. When the bending plate 402 needs to be disassembled and replaced, the locking rod 303 is pulled towards the pressing mechanism 5, so that the locking rod 303 is pulled out of the interior of the connecting column 401. This allows the operator to remove the top of the two sets of bending plates 402 from the locking mechanism 3, which facilitates the replacement of the bending plates 402 and the maintenance of the bending machine, thus extending the service life of the bending machine. When the two sets of moving blocks 204 move, they drive the moving plate 301 to move. The mutual approach and distance of the two sets of moving plates 301 drive the mutual approach and distance of the connecting column 401, thereby changing the opening angle of the bending plate 402.

[0035] In one embodiment, the bending mechanism 4 includes a first connecting post 401 disposed inside the slot 302 and cooperating with the engaging rod 303. A bending plate 402 is disposed at the middle of the outer side of the first connecting post 401. Two sets of bending plates 402 are connected by a second connecting post 403. Both ends of the second connecting post 403 are provided with connecting grooves 404. A first protrusion 405 is disposed inside the connecting groove 404 and cooperating with it. A follower block 406 is disposed on one side of the first protrusion 405, and a second limiting bracket 407 is disposed on the outer side of the follower block 406 and cooperating with it. The top of the follower block 406 is provided with a second spring 408, and the two sets of second springs 408 are connected by a base plate 409. On the side of the follower block 406 away from the angle adjustment mechanism 2, a scale plate 410 that cooperates with the bending plate 402 is provided. The cross-section of the connecting groove 404 is a trapezoidal structure. Under the action of the connecting groove 404 and the first protrusion 405 being locked together, the scale plate 410 can move with the movement of the second connecting column 403, so that the operator can easily observe the bending angle according to the position of the bending plate 402, ensuring the operator's accurate grasp of the bending angle.

[0036] The working principle of bending mechanism 4: When the opening angle of bending plate 402 changes, under the mutual clamping action of connecting groove 404 and first protrusion 405, follower block 406 can move along the path of limit frame 407. At the same time, scale plate 410 can move with connecting column 403, making it convenient for the operator to observe the bending angle according to the position of bending plate 402, ensuring the operator's accurate grasp of the bending angle. When pressing mechanism 5 bends the workpiece, under the elastic action of spring 408, pressing mechanism 5 presses the workpiece onto base plate 409, preventing the workpiece from being bent. The connection between the two sets of connecting plates 503 is directly in contact to ensure the surface quality of the workpiece after bending. When replacing the bending plate 402, after the operator removes the top of the two sets of bending plates 402 from the locking mechanism 3, the operator further moves the two sets of bending plates 402 upward along the path of the second limiting frame 407 to remove the two sets of bending plates 402 from the inside of the second limiting frame 407. At the same time, the connecting groove 404 and the first protrusion 405 are no longer locked together. Then the second connecting post 403 connecting the two sets of bending plates 402 is removed, thereby realizing the disassembly of the bending plate 402 and facilitating the replacement of the bending plate 402.

[0037] In one embodiment, the pressing mechanism 5 includes a pressing block 501 disposed above the bending mechanism 4. Several springs 502 are disposed on both sides of the pressing block 501. A connecting plate 503 connected to the pressing block 501 is disposed on the side of the springs 502 away from the pressing block 501. Several second protrusions 504 are disposed on the side of the connecting plate 503 away from the pressing block 501. An electric telescopic rod 505 is disposed at the top of the pressing block 501. The electric telescopic rod 505 is connected to the worktable 1 via a connecting frame 506. The springs 502 are evenly arranged and rectangularly distributed on one side of the pressing block 501. Under the extension of the electric telescopic rod 505, the workpiece can be pressed and bent. After bending, under the contraction of the electric telescopic rod 505, the elasticity of the springs 502, and the squeezing action of the second protrusions 504, the pressure on the workpiece surface is slowly released after bending, effectively preventing workpiece rebound and ensuring workpiece production quality.

[0038] In addition, it should be noted that, in order to ensure that the workpiece can be prevented from springing back, the connecting plate 503 and the several second protrusions 504 are all made of flexible material.

[0039] The working principle of the pressing mechanism 5 is as follows: By activating the electric telescopic rod 505, the workpiece is pressed down and bent under the extension action of the electric telescopic rod 505. After bending, the workpiece surface is slowly released under the contraction action of the electric telescopic rod 505, the elastic action of the spring 3 502, and the squeezing action of the second protrusion 504, thereby effectively preventing the workpiece from springing back and ensuring the production quality of the workpiece.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0041] In practical applications, the bending angle of the bending mechanism 4 is adjusted by the angle adjustment mechanism 2. Then, the operator places the workpiece to be bent on the bending mechanism 4 and then the pressing mechanism 5 is activated to bend the workpiece. When the bending plate 402 needs to be replaced, the bending plate 402 is removed by the locking mechanism 3 for replacement.

[0042] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the angle adjustment mechanism 2, the locking mechanism 3, the bending mechanism 4, and the pressing mechanism 5, not only can the included angle between the bending plates 402 be changed and observed quickly and accurately, improving the production efficiency and flexibility of the bending machine, but it can also prevent the workpiece from springing back after bending, ensuring the quality of workpiece production. Furthermore, it enables the rapid installation and disassembly of the bending plates 402, simplifying the maintenance process of the bending machine and extending its service life. Through the locking mechanism 3, under the action of the spring-304, the connecting column-401 and the locking rod-303 are locked together. When it is necessary to disassemble the bending plates 402... During removal and replacement, by pulling the locking rod 303 towards the pressing mechanism 5, the locking rod 303 is pulled out of the interior of the connecting column 401, allowing the operator to remove and replace the bending plate 402, facilitating the maintenance of the bending machine and extending its service life. Through the pressing mechanism 5, the workpiece can be pressed down and bent under the extension action of the electric telescopic rod 505. After bending, the pressure on the workpiece surface is slowly released under the contraction action of the electric telescopic rod 505, the elastic action of the spring 502, and the squeezing action of the second protrusion 504, thereby effectively preventing the workpiece from springing back and ensuring the production quality of the workpiece.
