[0001] This application relates to the technical field of bending equipment, and in particular to a bending mechanism. Background Technology

[0002] A bending machine is a type of mechanical equipment used in metal processing. It can bend metal materials into the desired shape. Bending machines are characterized by their speed, precision, and efficiency, and are widely used in various fields of manufacturing.

[0003] The existing bending machine includes a base plate, a pressure plate, and a clamp. The pressure plate is set above the base plate and the pressure plate and the base plate are offset from each other. The clamp is set on the upper surface of the base plate and is connected and fixed to the base plate. The operator places the metal sheet to be bent on the base plate, and then uses the clamp to clamp and fix the metal sheet. Then the operator moves the pressure plate toward the base plate. During the movement of the pressure plate, the metal sheet is bent at the outer end of the base plate.

[0004] Regarding the aforementioned technologies, when using a bending machine, workers need to manually place the metal plate and then use clamps to clamp and fix it, which is time-consuming and labor-intensive, resulting in the drawback of low working efficiency of the bending machine.

[0007] By adopting the above technical solution, the conveyor belt transports the metal plate to the rotating plate and it falls into the placement slot. One end of the metal plate is on the outside of the rotating plate. The support column rotates, causing the rotating plate to rotate towards the pressure plate. During the rotation of the rotating plate, the first rotating component drives the threaded sleeve to rotate.

The second rotating assembly includes a lever plate and a limiting plate. One end of the lever plate is hinged to the side wall of the second transmission rod. The end of the lever plate away from the second transmission rod can extend to the tooth ridge of the second gear. The limiting plate is located below the lever plate. The limiting plate and the second transmission rod are fixedly connected and perpendicular to each other.

[0013] By adopting the above technical solution, during the downward movement of the first rack, the first rack drives the second transmission rod to move, the second transmission rod drives the limiting plate and the lever to move, and the lever rotates upward under the obstruction of the second gear. During the upward rotation of the first rack, the first rack drives the second transmission rod to move upward, the second transmission rod drives the limiting plate and the lever to move upward, and at the same time, during the upward movement of the lever, the end of the lever away from the second transmission rod extends between the teeth of the second gear. Under the support of the limiting plate, the lever drives the second gear to rotate, so that the second rotating assembly realizes the function of driving the second gear to rotate.

During the rotation of the rotating plate, the third gear and the third rack first come into contact and mesh. As the rotating plate continues to rotate, the third rack causes the third gear to rotate. The third gear drives the threaded sleeve to rotate. Under the guidance of the telescopic rod, the threaded sleeve drives the screw to move upward. The screw drives the clamping plate to move upward, so that the clamping plate releases its grip on the metal sheet. The setting of the third rack facilitates the upward movement of the clamping plate.

[0020] Optionally, a fixing block is fixed between the first rack and the pressure plate.

[0021] By adopting the above technical solution, the setting of the fixing block realizes the connection between the first rack and the pressure plate.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a bending mechanism.

[0031] refer to Figure 1 A bending mechanism includes a rotating plate 4, which is parallel to the ground. A housing 9 is located directly below the rotating plate 4, with its upper end abutting against the lower surface of the rotating plate 4. A conveyor belt 5 is located on one side of the rotating plate 4, conveying metal sheets towards the rotating plate 4. A support platform 2 is located on the side of the rotating plate 4 away from the conveyor belt 5. A pressure plate 1 is located on the side of the support platform 2 facing the rotating plate 4, connected to the support platform 2. The pressure plate 1 is perpendicular to the rotating plate 4 and is located outside the rotating plate 4. The housing 9 provides support for the rotating plate 4, preventing it from wobbling.

[0032] refer to Figure 1 and Figure 2The upper surface of the rotating plate 4 has multiple placement slots 42, which are arranged sequentially along the edge of the upper surface of the rotating plate 4. A support 6 is provided at each placement slot 42 on the rotating plate 4. The support 6 includes a second support plate 61 and a third support plate 62. The second support plate 61 is fixedly connected to and perpendicular to the upper surface of the rotating plate 4. The third support plate 62 is fixedly connected to the upper sidewall of the second support plate 61, and the second support plate 61 and the third support plate 62 are perpendicular. A clamping plate 43 is provided above the placement slot 42, parallel to the rotating plate 4, and the clamping plate 43 is engaged with the placement slot 42. A threaded sleeve 45 is rotatably connected at the center of the lower surface of the third support plate 62, with the threaded sleeve 45 extending along the length of the third support plate. A screw 44 is fixedly connected to the center of the upper surface of the clamping plate 43. The length direction of the screw 44 is perpendicular to the clamping plate 43. The upper end of the screw 44 is inside the threaded sleeve 45 and threadedly connected to the threaded sleeve 45. A telescopic rod 46 is fixedly connected to the lower surface of the third support plate 62. The length direction of the telescopic rod 46 is parallel to the threaded sleeve 45. The bottom end of the telescopic rod 46 is fixedly connected to the upper surface of the clamping plate 43. The telescopic rod 46 is composed of multiple rod sections that are sleeved together and slidably connected to each other. A support column 41 is fixedly connected to the center of the lower surface of the rotating plate 4. The support column 41 is perpendicular to the rotating plate 4. The bottom end of the support column 41 is rotatably connected to the ground. A first rotating assembly 7 that drives the threaded sleeve 45 to rotate is provided at the rotating plate 4.

[0033] The first rotating assembly 7 includes a third gear 71 and a second rack 72. The third gear 71 is disposed at the threaded sleeve 45 and perpendicular to the threaded sleeve 45. The threaded sleeve 45 passes through the third gear 71 and is fixedly connected to it. The second rack 72 is connected and fixed to one side wall of the conveyor belt 5. The second rack 72 is arc-shaped and meshes with the third gear 71.

[0034] The metal sheet falls from the conveyor belt 5 into the placement slot 42 of the rotating plate 4, with one end of the metal sheet outside the rotating plate 4. The support column 41 rotates, causing the rotating plate 4 to rotate. The rotating plate 4 moves the metal sheet, and at the same time, the rotating plate 4 moves the second support plate 61. The second support plate 61 moves the third support plate 62. The third support plate 62 moves the threaded sleeve 45, the telescopic rod 46, the third gear 71, and the clamping plate 43. During the movement of the third gear 71, it first contacts and meshes with the second rack 72. As the threaded sleeve 45 continues to move the third gear 71, the second rack 72 causes the third gear 71 to rotate. The third gear 71 drives the threaded sleeve 45 to rotate. Under the guidance of the telescopic rod 46, the threaded sleeve 45 moves the clamping plate 43 downward. The clamping plate 43 abuts against the metal sheet and clamps and fixes the clamping plate 43, making it difficult for the metal sheet to move freely on the rotating plate 4.

[0035] refer to Figure 2 and Figure 3The support platform 2 has a vertical groove 21 on the side facing the pressure plate 1. A slider 22 is slidably connected to the support platform 2 along the length of the groove 21. A moving component 3 is set at the support platform 2 to drive the pressure plate 1 to move up and down. The moving component 3 includes a first rack 31, a motor 32 and a first gear 33. The first rack 31 and the slider 22 are fixedly connected to the side facing the pressure plate 1. The length direction of the first rack 31 is parallel to the length direction of the groove 21. A fixing block 312 is fixedly connected to the side of the first rack 31 away from the slider 22. The fixing block 312 is fixedly connected to the pressure plate 1 on the side away from the first rack 31. The motor 32 is set inside the support platform 2 and fixedly connected to the support platform 2. The output shaft of the motor 32 extends to the outside of the support platform 2 and is fixedly connected to the first gear 33. The first gear 33 meshes with the first rack 31.

[0036] When the rotating plate 4 moves the metal plate to the pressure plate 1, the motor 32 is started. The motor 32 drives the first gear 33 to rotate. Under the guidance of the slider 22, the first gear 33 drives the first rack 31 to move downward. The first rack 31 moves at a specified speed. The fixed block 312 drives the pressure plate 1 to move downward. The pressure plate 1 bends the metal sheet at the end outside the placement groove 42.

[0037] refer to Figure 2 , Figure 3 and Figure 4 A first bevel gear 411 is horizontally installed at the support column 41, and the support column 41 passes through and is fixedly connected to the first bevel gear 411. A first support plate 47 is installed between the support column 41 and the load-bearing platform 2. The length direction of the first support plate 47 is parallel to the support column 41, and the bottom end of the first support plate 47 is fixedly connected to the ground. A first transmission rod 471 is installed at the upper end of the first support plate 47. The length direction of the first transmission rod 471 is perpendicular to the first support plate 47, and the first transmission rod 471 passes through the first support plate 47 and... The first support plate 47 is rotatably connected. The first transmission rod 471 is fixedly connected to the second bevel gear 472 at one end near the support column 41. The second bevel gear 472 meshes with the first bevel gear 411. The first transmission rod 471 is fixedly connected to the second gear 473 at the other end away from the second bevel gear 472. The second gear 473 is perpendicular to the first transmission rod 471. The lower end of the first rack 31 is fixedly connected to the second transmission rod 311 along its own length. A second rotating assembly 8 is provided at the second transmission rod 311 to drive the second gear 473 to rotate.

[0038] The second rotating assembly 8 includes a lever plate 81 and a limiting plate 82. The lever plate 81 and the bottom side wall of the second transmission rod 311 are hinged together. The limiting plate 82 is located directly below the lever plate 81 and is fixedly connected to the side wall of the second transmission rod 311.

[0039] As the first rack 31 moves downward, the second gear 473 blocks the movement, causing the lever 81 to rotate upward. The lever 81 cannot easily drive the second gear 473 to rotate. At the same time, the second transmission rod 311 moves the lever 81 below the second gear 473. As the first rack 31 drives the second transmission rod 311 upward, the limiting plate 82 blocks the lever 81, making it difficult for the lever 81 to rotate downward. The end of the lever 81 away from the second transmission rod 311 abuts against the second gear 473. As the lever 81 moves upward, it drives the second gear 473 to rotate. The second gear 473 drives the first transmission rod 471 to rotate. The first transmission rod 471 drives the second bevel gear 472 to rotate. The second bevel gear 472 drives the first main gear to rotate. The first blow gear adjusts the support column 41 to rotate. The support column 41 drives the rotating plate 4 to rotate. There is no need to provide power to the rotating plate 4 separately, thus saving resources.

[0040] refer to Figure 1 and Figure 2 A fixed rod 48 is vertically installed at the center of the upper surface of the rotating plate 4. The bottom end of the fixed rod 48 passes through the support column 41 of the rotating plate 4 and extends along the length of the support column 41 to the ground and is fixedly connected to the ground. Both the rotating plate 4 and the support column 41 are rotatably connected to the fixed rod 48. A connecting rod 481 is fixedly connected to the upper side wall of the fixed rod 48. The length of the connecting rod 481 is perpendicular to the fixed rod 48. A third rack 49 is fixedly connected to the end of the connecting rod 481 away from the fixed rod 48. The third rack 49 is horizontally set and is arc-shaped. The third rack 49 and the third gear 71 mesh and fit together.

[0041] After the metal plate is bent, the rotating plate 4 drives the metal plate to rotate in the direction of the transmission belt. The rotating plate 4 drives the third gear 71 to move. During the movement of the third gear 71, it meshes with the third rack 49. As the third gear 71 continues to move with the rotating plate 4, the third rack 49 causes the third gear 71 to rotate. The third gear 71 drives the threaded sleeve 45 to rotate. Under the guidance of the telescopic rod 46, the threaded sleeve 45 drives the screw 44 to move upward. The screw 44 drives the clamping plate 43 to move upward, releasing the clamping plate 43 from the metal sheet. Then the metal sheet is removed from the placement groove 42.

[0042] refer to Figure 1 and Figure 5 The housing 9 has openings at both the top and bottom. Multiple rollers 91 are rotatably connected to the upper surface of the circumferential sidewall of the housing 9. The rollers 91 are arranged sequentially along the circumferential sidewall of the housing 9, and the rollers 91 abut against the lower surface of the rotating plate 4. During the rotation of the rotating plate 4, the rollers 91 are driven to roll. The arrangement of the rollers 91 reduces the friction between the housing 9 and the rotating plate 4, thus facilitating the rotation of the rotating plate 4.

[0043] The implementation principle of a bending mechanism in this application embodiment is as follows: The conveyor belt 5 conveys the metal sheet to the rotating plate 4, and the metal sheet falls into the placement groove 42. One end of the metal sheet is outside the rotating plate 4. The rotating plate 4 rotates, driving the metal sheet to move. During the rotation of the rotating plate 4, the third gear 71 and the second rack 72 abut and mesh. As the rotating plate 4 drives the third gear 71 to continue moving, the second rack 72 causes the third gear 71 to rotate. The third gear 71 drives the threaded sleeve 45 to rotate. Under the guidance of the telescopic rod 46, the threaded sleeve 45 drives the clamping plate 43 to move towards the metal sheet. The clamping plate 43 and the bottom wall of the placement groove 42 are in contact with the metal sheet. The metal sheet is clamped and fixed, making it difficult for the metal sheet to move freely on the rotating plate 4. When the metal sheet is bent, as the rotating plate 4 moves the metal sheet toward the conveyor belt 5, the third gear 71 and the third rack 49 mesh. As the rotating plate 4 continues to move the third gear 71, the third rack 49 causes the third gear 71 to rotate. The third gear 71 drives the threaded sleeve 45 to rotate, causing the clamping plate 43 to move upward, releasing the clamping and fixing of the metal sheet, and removing the metal sheet from the placement slot 42. This eliminates the need for manual clamping and unclamping of the metal sheet, saving time and improving the working efficiency of the bending machine.

[0044] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
