Vertical blocks 2 are symmetrically arranged on the top surface of the workbench 1. The top surfaces of the two vertical blocks 2 are provided with through grooves 3 for placing steel pipes. The steel pipes to be bent can be placed in the inner cavities of the two through grooves 3 first, so that the two through grooves 3 can preliminarily restrict the through pipes. One of the vertical blocks 2 is fixed on the top surface of the workbench 1, and the other vertical block 2 is in frictional contact with the workbench 1. An electric telescopic column is fixed on one side of one of the vertical blocks 2, and the free end of the electric telescopic column 9 is fixedly connected to the other vertical block 2. The electric telescopic column 9 is fixed on one side of the vertical block 2 fixedly installed on the top surface of the workbench 1. The other vertical block 2 can be driven to move by the electric telescopic column 9, thereby changing the distance between the two vertical blocks 2.

[0027] A driving motor 4 is fixedly mounted on one side of one of the vertical blocks 2 through an L-shaped bracket. The driving motor 4 can rotate forward and reversely. A rotating block 5 is fixedly connected to the output shaft of the driving motor 4. One side of the rotating block 5 is in frictional contact with one side of the vertical block 2. A groove 6 for placing a steel pipe is provided on the side of the rotating block 5 facing the vertical block 2. A threaded rod 7 is threadedly connected to the top surface of the rotating block 5. The bottom end of the threaded rod 7 penetrates through the inner cavity of the groove 6 and is rotatably connected to a pressing block 8. After the steel pipe is placed in the inner cavity of the through groove 3, one end of the steel pipe is allowed to enter the inner cavity of the groove 6. After entering, the threaded rod 7 is rotated to allow the threaded rod 7 to drive the pressing block 8 to move downward, so that the pressing block 8 can The steel pipe is clamped and fixed, and one side wall of the groove 6 is not hollowed out, so that one side of the pressure block 8 can be in friction contact with the inner wall of one side of the groove 6. By turning on the drive motor 4, the drive motor 4 can drive the rotating block 5 to rotate, so that the rotating block 5 can drive the steel pipe to rotate, and then the steel pipe can be adjusted to other bending angles, and the different angles of the steel pipe can be adjusted in conjunction with the forward and reverse rotation of the drive motor 4, and the setting of the electric telescopic column 9 can drive the steel pipe to move, so that the steel pipe can be bent twice, avoiding the need to frequently disassemble and assemble the steel pipe for secondary bending and changing the bending angle, thereby improving the efficiency of bending the steel pipe.

[0028] A fixed box 10 is fixedly provided on the top surface of the workbench 1 and on one side of the two vertical blocks 2. A circular block 11 is provided on the top surface of the fixed box 10. A rotating motor 12 is fixedly provided on the bottom surface of the inner cavity of the fixed box 10. The rotating motor 12 can rotate forward and reverse. The output shaft of the rotating motor 12 is fixedly connected to the bottom surface of the circular block 11. By turning on the rotating motor 12, the rotating motor 12 can drive the circular block 11 to rotate on the top surface of the fixed box 10.

[0029] The circular block 11 is provided with arc grooves 13 for placing steel pipes in a circular array on the circumference of the circular block 11, and a hydraulic column 14 is fixedly provided on the circumference of the circular block 11. The free end of the hydraulic column 14 is fixedly provided with an inverted L-shaped connecting frame 15, and the end of the connecting frame 15 away from the hydraulic column 14 is fixedly provided with a limit block 16 for limiting the steel pipe. One side of the limit block 16 is also provided with an arc groove 13 consistent with the structure of the circumference of the circular block 11. When the steel pipe enters the inner cavity of the arc groove 13, the hydraulic column 14 is turned on to drive the connecting frame 15 to move, so that the connecting frame 15 drives the limit block 16 to move, so that the arc groove 13 on one side of the limit block 16 can be against the steel pipe, and the rotating motor 12 is turned on at this time to allow the rotating motor 12 to rotate. The circular block 11 is driven to rotate, and the limiting block 16 is driven to rotate through the circular block 11, the hydraulic column 14 and the connecting frame 15, so that the limiting block 16 can rotate clockwise with the center point of the circular block 11 as the axis. The clockwise rotating limiting block 16 will press against one side of the steel pipe, and the arc groove 13 will press against the other side of the steel pipe. By continuously rotating the circular block 11, the limiting block 16 can gradually apply pressure to the steel pipe, so that the bending area of ​​the steel pipe can gradually fit around the arc groove 13 to achieve the effect of bending the steel pipe. After the rotating motor 12 drives the circular block 11 to rotate clockwise for a certain number of degrees, it can rotate counterclockwise for a certain number of degrees, so that the limiting block 16 can move to its original position.

[0030] The positions of the groove 6 , the arc groove 13 , the limit block 16 and the two through grooves 3 are all arranged in the same horizontal plane, ensuring that after the steel pipe is placed in the inner cavities of the two through grooves 3 , the steel pipe will also be in the inner cavities of the groove 6 and the arc groove 13 .

[0031] Working principle:

[0032] The steel pipe bending equipment places the steel pipe to be bent in the inner cavity of the two through grooves 3, and allows one end of the steel pipe to enter the groove 6. At this time, the threaded rod 7 is rotated so that the threaded rod 7 drives the pressure block 8 to move downward, so that the pressure block 8 clamps and fixes the steel pipe. At this time, the electric telescopic column 9 is turned on to drive the vertical block 2 to move, and then drives the steel pipe to move so that one end of the steel pipe can enter the arc groove 13. At this time, the hydraulic column 14 is started to drive the limit block 16 to move through the connecting frame 15, so that the limit block 16 is against one side of the steel pipe. At this time, the rotating motor 12 is turned on to drive the circular block 11 to rotate, so that the circular block 11 rotates clockwise with the center point of the circular block 11 as the axis through the limit block 16. , so that the limit block 16 can be against one side of the steel pipe, and the arc groove 13 will be against the other side of the steel pipe, so that when the limit block 16 rotates clockwise, it will gradually apply pressure to the steel pipe, so that the bending area of ​​the steel pipe will gradually fit the 13 sides of the arc groove. When the limit block 16 rotates clockwise by ninety degrees, the steel pipe will be bent by ninety degrees. When a secondary bending is required, the steel pipe can be moved by the electric telescopic column 9 to change the bending area. When the bending angle needs to be changed, the drive motor 4 is turned on, and the drive motor 4 drives the rotating block 5 to rotate, so that the rotating block 5 can drive the steel pipe to rotate, thereby changing the bending angle, avoiding the need to frequently disassemble and assemble the steel pipe for secondary bending and changing the bending angle, and improving the efficiency of steel pipe bending.
