[0029] The bending assembly 2 includes a mounting groove 21 opened on the top of the operating table 1, and a first threaded rod 22 is rotatably connected inside the mounting groove 21. A moving block 23 that fits the inner wall of the mounting groove 21 is threadedly connected to the first threaded rod 22, and two bending columns 24 are fixedly connected to the top of the moving block 23. A driving motor 25 is fixedly connected to one side of the operating table 1, one end of the first threaded rod 22 rotates and penetrates the operating table 1, and the extended end is fixedly connected to the output end of the driving motor 25 through a coupling.

[0030] In the above embodiment, the pipe is placed on the top of the two fixed plates 6, and the two ends of the pipe are clamped and fixed by the provided clamping assembly 7. The driving motor 25 is started to drive the first threaded rod 22 to rotate, and the moving block 23 is driven to move inside the mounting groove 21, thereby driving the two bending columns 24 to move. Under the restriction of the two clamping assemblies 7, the pipe is gradually bent. When bending, the pipe tilts, driving the fixed plate 6 and the clamping assembly 7 to rotate on the top of the slider 4. At the same time, the tilting of the pipe will drive the clamping assembly 7 to move, and then drive the fixed plate 6 to move, thereby driving the slider 4 to slide inside the groove 3. The first spring 5 contracts to complete the bending work, avoiding bending at the connection between the pipe and the clamping assembly 7, thereby ensuring the bending effect of the pipe.

[0031] Furthermore, the clamping assembly 7 includes a mounting frame 701 fixedly connected to the fixing plate 6, and fixed rods 702 are fixedly connected to both sides of the mounting frame 701, and a rotating rod 703 is hinged at one end of the fixed rod 702. A first connecting rod 704 is provided at the top end of the rotating rod 703, and a second connecting rod 705 is provided at the bottom end. One end of the first connecting rod 704 and the second connecting rod 705 respectively slide through the mounting frame 701, and one end of the second connecting rod 705 is connected to a side clamping plate 707 through an elastic part 706.

[0032] A second threaded rod 708 penetrates through and is threadedly connected to the top of the mounting bracket 701 . A knob 709 is fixedly connected to the top of the second threaded rod 708 , and a main clamping plate 710 is rotatably connected to the bottom.

[0033] A driving plate 711 is rotatably connected to the second threaded rod 708 , and two sides of the driving plate 711 are hinged to the two first connecting rods 704 via two third connecting rods 712 .

[0034] Long holes 713 are formed at both ends of the rotating rod 703 , and one end of the first connecting rod 704 and the second connecting rod 705 are both rotatably connected to a clamping block 714 that slides inside the long hole 713 .

[0035] On the basis of the above embodiment, when clamping and fixing the pipe, the pipe is placed on the top of the fixing plate 6, and then the second threaded rod 708 is rotated by turning the knob 709, thereby driving the main clamping plate 710 to descend and clamp the top of the pipe. At the same time, the driving plate 711 is driven to descend by the second threaded rod 708, thereby driving one end of the two third connecting rods 712 to descend. The third connecting rod 712 rotates to drive the first connecting rod 704 to move on the mounting frame 701, and drives the rotating rod 703 to rotate around the fixing rod 702. At this time, the block 714 slides inside the long hole 713, driving the second connecting rod 705 to move on the mounting frame 701, and driving the side clamping plate 707 to move through the elastic part 706. At this time, the two side clamping plates 707 are close to each other to clamp the two sides of the pipe. By fixing the top and both sides of the pipe, the clamping effect of the pipe is improved.

[0036] Furthermore, the elastic portion 706 includes a limiting groove 7061 formed on the second connecting rod 705 , and the interior of the limiting groove 7061 is elastically connected to a connecting rod 7063 slidably connected to the limiting groove 7061 via a second spring 7062 , and one end of the connecting rod 7063 is hinged to the side clamping plate 707 .

[0037] On the basis of the above embodiment, by providing a limit groove 7061, a second spring 7062 and a connecting rod 7063, it is convenient to clamp and fix the two sides of pipes of different diameters, and by hingedly connecting one end of the connecting rod 7063 to the side clamping plate 707, the side clamping plate 707 and the pipe are more closely fitted.

[0038] The implementation principle of a workbench for a bending machine in an embodiment of the present application is as follows: a pipe is placed on top of two fixed plates 6, both ends of the pipe are clamped and fixed by a set clamping assembly 7, and then the pipe can be bent by a set bending assembly 2. When bending, the pipe is tilted, driving the fixed plates 6 and the clamping assembly 7 to rotate on the top of the slider 4. At the same time, the tilting of the pipe will drive the clamping assembly 7 to move, and then drive the fixed plates 6 to move, thereby driving the slider 4 to slide inside the groove 3, and the first spring 5 contracts to complete the bending work.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
