[0034] Working principle: before use, first set the pipe bending control program through the PLC control panel 15, then start the preparation work, control the third electric hydraulic rod 23 to retract through the PLC control panel 15, and the telescopic end of the third electric hydraulic rod 23 drives the sliding bracket 26 to slide on the inner side of the limiting slide groove 22 away from the supporting side plate 3, and the movement of the sliding bracket 26 drives the servo motor 24 to move, thereby driving the pipe bending tube 25 to move on the inner side of the perforation 8, and the movement of the pipe bending tube 25 drives the annular baffle 29 to move close to the supporting side plate 3, until the side of the annular baffle 29 close to the supporting side plate 3 is close to the side of the guide inclined plate 7 away from the supporting side plate 3, and then the servo motor 24 is controlled to start through the PLC control panel 15, and the servo The driving end of the motor 24 drives the bending tube 25 to rotate, and the rotation of the bending tube 25 drives the annular baffle 29 to rotate. The rotation of the annular baffle 29 drives the fixing notch 30 to rotate to the position directly above the annular baffle 29, and then the PLC control panel 15 controls the first electric hydraulic rod 17 and the second electric hydraulic rod 19 to retract, and the telescopic end of the first electric hydraulic rod 17 drives the lifting block 16 to move upward, and the movement of the lifting block 16 drives the concave bending roller 6 to move upward to the top of the second limiting groove 5, and the telescopic end of the second electric hydraulic rod 19 drives the lifting plate 18 to move upward, and the movement of the lifting plate 18 drives the concave limiting roller 9 to move upward to the top of the first limiting groove 4, and the preparation work before bending is completed.

At this time, the concave bending roller 6 and the bending tube 25 squeeze the steel pipe body 11 in the middle, and then the bending program can be started to perform the bending operation.

[0036] When the pipe bending operation is started, the PLC control panel 15 controls the third electric hydraulic rod 23 and the servo motor 24 to start synchronously. The third electric hydraulic rod 23 slowly extends according to the diameter of the steel pipe body 11 and the speed of the servo motor 24 according to the preset program. The rotation of the servo motor 24 drives the pipe bending cylinder 25 to rotate.

Then, the guide inclined plate 7 is tilted to rotate. The oblique guide extrusion and the steel pipe body 11 nested on the outside of the bending tube 25 are offset to form a spring-shaped tube disc. At the same time, the third electric hydraulic rod 23 continuously pushes the bending tube 25 to move from the side of the supporting side plate 3 close to the servo motor 24 to the other side of the supporting side plate 3 on the inner side of the perforation 8. When the steel pipe body 11 is completely bent, the bending program is closed and the pipe removal program is started through the PLC control panel 15. The PLC control panel 15 controls the first electric hydraulic rod 17 and the second electric hydraulic rod 19 to retract to the top, and then the PLC control panel 1 5. The third electric hydraulic rod 23 is controlled to extend, and the telescopic end of the third electric hydraulic rod 23 pushes the sliding bracket 26 to slide inside the limiting slide groove 22 close to the supporting side plate 3 until the sliding bracket 26 is close to the side of the supporting side plate 3, and then the fixing nut 32 is screwed away from the fixing arc plate 33 by external force until the fixing arc plate 33 is loosened, and then the fixing arc plate 33 is rotated to make the clamping interface 34 disengage from the threaded rod 31, and then the end of the steel pipe body 11 close to the clamping notch 30 is taken out of the annular baffle 29 by external force, and the two pull rings 4 are pulled by external force. 0 move toward each other, the movement of the pull ring 40 drives the movable pull rod 39 to move, and the movable pull rod 39 drives the limit baffle 37 and the fixed plug rod 36 to move away from the fixed slot 28, until the end of the fixed plug rod 36 away from the limit baffle 37 is completely separated from the interior of the fixed slot 28, and then the annular baffle 29 is pulled away from the bending tube 25 by external force, and the movement of the annular baffle 29 drives the plug-in ring 41 to move, until the plug-in ring 41 is completely separated from the inner side of the bending tube 25, at this time, the steel pipe body 11 that has been bent can be removed from the outer side of the bending tube 25.
