the reinforcement is to increase the strength of the corresponding position of the pipeline by welding at the corresponding position inside the pipeline.
In implementation, the detection module can measure the appearance of the pipeline to be bent in a mode of laser scanning, influencing shooting and caliper measurement, and can measure the appearance of the pipeline to be bent, and the measurement form and the measurement instrument are not unique.
According to the invention, the bending module, the detection module, the outer shaping module and the inner shaping module are arranged to carry out appearance correction and structure reinforcement on the bent pipeline, so that the appearance precision of the bent pipeline is effectively improved, and meanwhile, the structural strength of the bent pipeline is improved, thereby effectively improving the bending precision of the pipeline.
Specifically, when the detection module measures the appearance of a single pipe to be bent, the pipe to be bent which is bent is shot from the tangential direction of the vertex of the bending part, a bent pipe image is formed, the bent pipe image is compared with a target image, and an external compensation strategy and/or an adjustment mode of an internal compensation strategy are determined according to the comparison result;
if the detection module judges that the pipe diameter of the bent pipe image at the vertex of the bending part is smaller than the target image, the detection module judges that the pipe is shaped by a compensation strategy outside the detection module;
if the detection module judges that the pipe diameter of the bent pipe image at the vertex of the bending part is larger than or equal to the target image, the detection module judges that the internal compensation strategy is used for shaping the pipeline;
if the detection module judges that the pipe diameter of the bent pipe image and the pipe diameter of the target image in the non-bending area are different from each other, the detection module judges that the pipe to be bent is unqualified;
wherein, the vertex of the bending part is the geometric center of the bending part corresponding to the pipe to be bent after completing bending; the non-bending area is the part of the pipeline to be bent, which is not bent. In the implementation, shooting the corresponding image of the horizontally placed pipeline from top to bottom, and comparing the image with the target image;
in the pipeline bending process, the corresponding bending part is divided into an inner bend and an outer bend, wherein the pipe wall corresponding to the inner bend can be extruded, the pipe wall corresponding to the outer bend can be stretched, in the process, if the outer bend is subjected to destructive deformation, the pipeline can be shrunken in the horizontal direction, at the moment, the pipe wall corresponding to the outer bend can be cut off to destroy the stress of the pipe wall, or the pipe is reinforced by the outer bend, and the tensile stress generated in the outer bend can be destroyed, so that the appearance of the pipeline is more similar to the target appearance.
The method has the advantages that whether the structural strength of the pipeline to be bent meets the standard is determined by measuring the appearance of the pipeline to be bent, and the shape correcting mode is determined according to the appearance of the pipeline to be bent, so that the integrity of the pipeline is effectively improved, and meanwhile, the bending precision of the pipeline is further improved.
Specifically, when the inner shaping module performs structural compensation on the inner compensation strategy of the pipeline to be bent, performing structural jacking according to the pipe diameter difference between the corresponding bent pipe image and the target image measured by the detection module, and welding the vertex of the bent part in a preset welding mode;

It can be understood that when the pipeline is bent and deformed, the outside pipeline is pulled to be thinner and the inside pipeline is extruded to be thicker by restoring the part of the pipeline with the reduced section to the original pipe diameter by utilizing the structure back-jacking mode, and the inner compensation strategy is applied to weld the outside pipeline wall at the moment, so that the wall thickness of the outside pipeline wall at the position where the outside pipeline is pulled to be thinner can be increased to the wall thickness which does not affect the integral structural strength of the pipeline, and at the moment, the completion of the inner compensation strategy can be judged.
The internal stress in the outer wall of the pipeline is released by utilizing the way of welding the pipeline, so that the bending precision of the pipeline is further improved while the strength of the outer wall of the pipeline is effectively improved.

the pre-extrusion strategy is to apply preset pressure from two ends of a to-be-bent pipe when the to-be-bent pipe of a single model is bent;
the preset pressure is in direct proportion to the pipe diameter difference of the target image and the single type of to-be-bent pipe.
In the implementation, the pipe diameter difference between the target image and the single type of to-be-bent pipeline is calculated in mm, and if the pipe diameter difference is 10mm, the corresponding applied pressure is 35N;
if the pipe diameter difference is measured to be 2mm, the corresponding applied pressure is 7N;
if the pipe diameter difference is measured to be 20mm, the corresponding applied pressure is 70N;

s4, recording parameters of the to-be-bent pipe subjected to the correction, and correcting the to-be-bent pipe with the same parameters by using a pre-correction mode;
the pre-straightening is to squeeze the bending pipe which is not bent.
9. The intelligent elbow control system for elbow rectification according to claim 8, wherein in said step S2, said to-be-bent pipe is set to bend in a horizontal direction, and a photographing angle is a top view angle perpendicular to a horizontal plane.
10. The intelligent elbow control system for elbow rectification according to claim 9, wherein in said step S4, said parameters of the pipe to be bent include the material composition, pipe diameter, wall thickness, bending radius and bending angle of the pipe to be bent.
