[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 1-Figure 6, an adjustable press brake that is easy to maintain, comprises an operating table 1, support columns 2 are fixedly connected at the four end corners of the lower end of the operating table 1, first slide grooves 7 are opened on both sides of the upper end of the operating table 1, clamping mechanisms 3 are arranged on both sides of the upper end of the operating table 1 and at positions corresponding to the first slide grooves 7, a press bending mechanism 4 is arranged at one end of the upper end of the operating table 1, a press bending plate 6 is fixedly connected at the middle part of the upper end of the operating table 1 and at a position corresponding to the press bending mechanism 4, and a moving mechanism 5 is arranged at the lower end of the operating table 1 and at a position located between the two clamping mechanisms 3.

[0036] Through the above structural design, it can be known that the plate that needs to be bent can be clamped by the bending mechanism 4, the plate can be clamped by the clamping mechanism 3, the position of the clamping mechanism 3 can be moved by the structure of the moving mechanism 5, and then the plate on the clamping mechanism 3 can be moved to a precise position by moving the clamping mechanism 3 and bent by the bending mechanism 4. At the same time, when it needs to be repaired, it can be repaired quickly.

[0037] Specifically, the bending mechanism 4 includes a fixed frame 8, which is located at one end of the upper end of the operating table 1, and both sides of the fixed frame 8 are fixedly connected to the two sides of the upper end of the operating table 1. The middle part of the upper end of the fixed frame 8 is fixedly connected with a first connecting frame 9, and the upper end of the fixed frame 8 is fixedly connected with an electric telescopic rod 10. The telescopic end of the electric telescopic rod 10 passes through the first connecting frame 9 and extends to the outer side of the lower end of the first connecting frame 9. One end of the electric telescopic rod 10 located on the outer side of the lower end of the first connecting frame 9 is fixedly connected with a fixed plate 11, and a plug-in slot 20 is provided at the lower end of the fixed plate 11.

[0038] Specifically, the bending mechanism 4 also includes a bending block 13, which corresponds to the bending plate 6 fixed on the operating table 1. The bending block 13 is plugged into the bending plate 6. The upper end of the bending block 13 is fixedly connected with a first slider 14, which is plugged into the plug-in slot 20. Limiting components 12 are provided on both sides of the upper end of the fixed plate 11.

[0039] Through the above structural design, it can be known that when the plate needs to be bent, the plate is clamped by the clamping mechanism 3, and the plate is moved to the specified position by the moving mechanism 5. After moving to the specified position, the electric telescopic rod 10 is started, and then the bending block 13 is driven to move downward by the start of the electric telescopic rod 10. The downward movement of the bending block 13 makes the bending block 13 fit the plate, and the plate can be bent by the cooperation of the bending block 13 and the bending plate 6.

[0040] Specifically, the clamping mechanism 3 includes a second connecting frame 21, both ends of the upper end of the second connecting frame 21 are provided with a handle 23, the middle part of the lower end of the handle 23 is fixedly connected with a first round rod 22, one end of the first round rod 22 away from the handle 23 passes through the second connecting frame 21 and extends to the inside of the second connecting frame 21, the first round rod 22 is slidably connected to the second connecting frame 21, one end of the first round rod 22 located inside the second connecting frame 21 is fixedly connected with a clamping plate 25, the lower end of the clamping plate 25 is fixedly connected with a clamping pad 26, and the first round rod 22 is connected to the inner side of the second connecting frame 21. A spring 24 is provided on the outside of the rod 22 and between the clamping plate 25 and the second connecting frame 21. The upper end of the spring 24 is fixedly connected to the top inside the second connecting frame 21, and the other end of the spring 24 is fixedly connected to the clamping plate 25. A connecting block 27 is fixedly connected to the middle of the lower end of the second connecting frame 21. One end of the connecting block 27 away from the second connecting frame 21 extends to the outside of the lower end of the operating table 1 through the first sliding groove 7. The second connecting frame 21 is slidably connected to the operating table 1, and the connecting block 27 is slidably connected to the first sliding groove 7.

[0041] Through the above structural design, it can be known that when the plate needs to be bent, the two clamping mechanisms 3 are moved to the end away from the operating table 1 through the moving mechanism 5, and then the handle 23 is pulled upward, and then the pulled handle 23 drives the clamping plate 25 to move upward through the first round rod 22. When the clamping plate 25 moves upward, the clamping plate 25 squeezes the spring 24, and then the spring 24 stores the squeezing force. After the movement is completed, the two sides of the plate can be placed inside the second connecting frame 21. After the placement is completed, the handle 23 is released, and then the spring 24 releases the stored force to The clamping plate 25 is pushed downward, and the downward movement of the clamping plate 25 drives the clamping pad 26 to fit with the plate, thereby clamping the plate. After clamping, the clamping mechanism 3 is moved by the moving mechanism 5, and then the plate can be bent when the plate is moved to the specified position. In the process of bending the plate, both sides of the plate are tilted upward inside the second connecting frame 21, and then the tilted plate squeezes the clamping plate 25, and then the squeezing force is stored by the spring 24, and the plate is continuously clamped by the stored force.

[0042] Specifically, the moving mechanism 5 includes a motor 28, and second sliders 30 are fixedly connected to both sides of the upper end of the motor 28. A second slide groove 29 is provided at the bottom of the operating table 1 and at a position corresponding to the second slider 30. The second slider 30 is slidably connected to the second slide groove 29. Second round rods 31 are fixedly connected to both ends of the motor 28. One end of the second round rod 31 away from the motor 28 is rotatably connected to the connecting block 27. A gear 32 is fixedly connected to the outer side of the second round rod 31 and at a position between the motor 28 and the connecting block 27. A rack 33 is provided at the upper end of the gear 32. The rack 33 is fixedly connected to the operating table 1, and the gear 32 is meshed with the rack 33.

[0043] Through the above structural design, it can be known that when the position of the clamping mechanism 3 needs to be moved, the motor 28 is started, and the start of the motor 28 drives the second round rods 31 at both ends to rotate, and the rotation of the second round rod 31 drives the gear 32 to move on the rack 33, and then the second round rod 31 drives the motor 28 to move, and the movement of the motor 28 drives the second slider 30 to move inside the second slide groove 29. When the second round rod 31 moves, the second round rod 31 drives the connecting block 27 to move inside the first slide groove 7, thereby completing the position movement of the clamping mechanism 3.

[0046] Through the above structural design, it can be known that when the bending block 13 needs to be disassembled or replaced, the connecting plate 17 is pulled upward, and the pulling of the connecting plate 17 drives the snap-fitting rod 19 to separate from the snap-fitting mouth 16, and at the same time, the connecting plate 17 drives the plug-in block 18 to separate from the plug-in connection with the slot 15, and the plug-in block 18 is separated from the slot 15, so that the plug-in block 18 is separated from the first slider 14, and the bending block 13 can be replaced after the plug-in block 18 is completely pulled out from the inside of the slot 15.
