The left side of the lower side wall of the mounting bracket 1 is provided with a spacing reference scale 59. The spacing reference pointer 58 and the spacing reference scale 59 are in the same vertical position. At this time, the spacing adjustment valve 57 can be manually turned in the forward and reverse directions, thereby driving the spacing adjustment screw 56 to rotate in the forward and reverse directions, and then the longitudinal position of the mounting bracket 52 is moved by the rotating seat 54.

[0026] The straightening mechanism 6 includes a rotating shaft 61, an angle adjusting bracket 62, a slide groove 63, an angle adjusting screw 64, a slider 65, a connecting rod 66, and a rotating seat 67.

The inside of the angle adjustment frame 62 is rotatably connected to evenly distributed straightening rollers 3. A straightening torsion valve 4 is fixedly connected to the upper end of the straightening roller 3 on the left rear side. After it moves to the designated position, the straightening adjustment torsion valve 7 can be manually turned forward and backward, causing the angle adjustment screw 64 to rotate forward and backward, thereby driving the slider 65 to adjust its left and right position. This, in turn, via the connecting rod 66, pushes the angle adjustment frame 62 around the central axis of the rotating shaft 61 to adjust the angle. At this time, the opening and closing angle of the angle adjustment frame 62 can be quickly determined by pointing the spacing reference pointer 58 to the spacing reference scale 59.

This indicates that the air conditioning copper pipe has been straightened. Then, the straightening adjustment valve 7 is turned in the opposite direction to remove the air conditioning copper pipe from the outer surface of the plug rod 8 and continue to straighten the next preheated air conditioning copper pipe.

[0027] The working principle of the bending and straightening machine for air conditioning copper pipes provided by this utility model is as follows: When the copper pipe bending and straightening machine is needed, the copper pipe can be preheated to a specified temperature. At this time, the heated copper pipe has a certain degree of ductility. Then, the spacing adjustment valve 57 can be manually turned in both directions, which will drive the spacing adjustment screw 56 to rotate in both directions. This will then push the longitudinal position of the movable mounting bracket 52 through the rotating seat 54. After it moves to the specified position, the straightening adjustment valve 7 can be manually turned in both directions, which will drive the angle adjustment screw 64 to rotate in both directions. This will then drive the slider 65 to adjust its left and right position. Finally, the connecting rod 66 will push the angle adjustment bracket 62 to adjust the angle around the central axis of the rotating shaft 61. At this point, the opening and closing angle of the angle adjustment frame 62 can be quickly determined by pointing the spacing reference pointer 58 to the spacing reference scale 59. Then, the heated angle adjustment frame 62 can be inserted into the interior of the horizontally arranged straightening rollers 3. The straightening rollers 3 in the fixed straightening mounting frame 2 and the straightening rollers 3 in the docking straightening frame 53 clamp the air conditioning copper pipe. Manually turn the straightening adjustment valve 7, which will insert the air conditioning copper pipe straightened by the straightening rollers 3 horizontally into the outer surface of the plug rod 8 until the entire air conditioning copper pipe is inserted into the plug rod 8. This indicates that the air conditioning copper pipe has been straightened. Then, turn the straightening adjustment valve 7 in the opposite direction to remove the air conditioning copper pipe from the outer surface of the plug rod 8 and continue the straightening operation of the next preheated air conditioning copper pipe.
