The bottom end of the convex plate 71 is fixedly connected with the top end of the bending workbench 1.
[0027] As a further implementation of this solution, the number of the electric telescopic rods 5 and the adjustment push plates 6 are respectively set to two. A support seat is installed on the upper end of the bending workbench 1. The electric telescopic rods 5 are fixed inside the support seats of the bending workbench 1. The electric telescopic rods 5 are fixed at the front end and the rear end of the bending workbench 1, so as to realize the function of adjusting the front and rear moving lengths of the offshore wind power stator bracket body 9, and can control the bending parts at the front end and the rear end of the offshore wind power stator bracket body 9;
[0028] As a further implementation of this solution, there are two convex plates 71. The convex plates 71 are fixedly connected to the upper part of the front end and the upper part of the rear end of the bending workbench 1. The limit sliding column 74 is fixedly connected between the two convex plates 71, which facilitates controlling the movement of the bending assembly 8 after starting the servo motor 72 and plays a role in limiting the movement of the bending plate 81. A limit rotation hole is provided inside the rear convex plate 71. The outer side of the rear end of the threaded rod 73 is rotatably connected to the inside of the convex plate 71, and the front end of the threaded rod 73 is rotatably connected to the front convex plate 71 through a bearing. The limit sliding column 74 is in the shape of a cylinder;
[0029] As a further implementation of this solution, there are two bending plates 81. The bending plates 81 are in the shape of an "L". The bending plates 81 are located between the two convex plates 71. The limit straight hole 83 is in the shape of a cylinder. The bending plates 81 are slidably connected to the outer side of the limit sliding column 74 through the limit straight holes 83.

At the same time, the front and rear bending assemblies 8 achieve the effect of bending the front end and the rear end of the offshore wind power stator support body 9 simultaneously, improving the bending efficiency and ensuring the accuracy of bending.
[0030] Workflow: When precisely bending both ends of the offshore wind power stator bracket body 9 simultaneously, place the offshore wind power stator bracket body 9 on the top of the folding table 4 and between two rotating cylinders 86 at the same time. According to the bending distances required at the front end and the rear end of the offshore wind power stator bracket body 9, start two electric telescopic rods 5. The electric telescopic rods 5 drive the position-adjusting push plates 6 to move. The two position-adjusting push plates 6 clamp and fix the offshore wind power stator bracket body 9. By the telescoping of the electric telescopic rods 5 and the movement of the position-adjusting push plates 6, control the distance of the forward and backward movement of the offshore wind power stator bracket body 9. After the control is completed, move the position-adjusting push plates 6 away from the offshore wind power stator bracket body 9. Start the first hydraulic rod 2. The first hydraulic rod 2 pushes the fixed pressing plate 3 to move. The fixed pressing plate 3 squeezes the offshore wind power stator bracket body 9. Under the combined action of the folding table 4 and the fixed pressing plate 3, achieve the effect of fixing the offshore wind power stator bracket body 9. When moving the bending assembly 8 to the position where the offshore wind power stator bracket body 9 needs to be bent, start the servo motor 72. The servo motor 72 drives the threaded rod 73 to rotate. One side of the servo motor 72 is fixedly connected to one side of the convex plate 71. After the threaded rod 73 rotates, drive the threaded hole 82 to move. The outer side of the threaded rod 73 is spirally connected to the inner side of the threaded hole 82 at the beginning of the folding plate 81. At the same time, due to the folding plate 81 being slidably connected to the limit slide column 74 through the limit straight hole 83, it is convenient for the folding plate 81 to move and at the same time plays a role in limiting the folding plate 81. When the above-mentioned offshore wind power stator bracket body 9 moves, the rotating cylinder 86 rotates, which can reduce the friction generated between the offshore wind power stator bracket body 9 and the device during movement and ensure that the offshore wind power stator bracket body 9 is not damaged. When the movement of the folding plate 81 is completed, start the second hydraulic rod 89. The second hydraulic rod 89 drives the bending plate 87 to rotate through the limit side seat 88 fixed on one side of the bending plate 87. One end of the bending plate 87 is rotatably connected to the outer side of the shaft roller 85 at the lower end, which plays a role in limiting the movement of the bending plate 87. At the same time, the lower part of the second hydraulic rod 89 is rotatably connected to the folding plate 81 through the limit side seat 88, which is convenient for driving the bending plate 87 to rotate after starting the second hydraulic rod 89, so that the bending plate 87 bends the offshore wind power stator bracket body 9. At the same time, the bending assemblies 8 at the front end and the rear end achieve the effect of bending the front end and the rear end of the offshore wind power stator bracket body 9 in opposite directions at the same time, improving the bending efficiency and ensuring the accuracy of bending.
