[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5 shown, a pipe straightening machine for guardrail processing of the present invention includes a main body mechanism 1. One side of the outer wall of the main body mechanism 1 is fixedly connected with a limiting mechanism 2, and the other side of the outer wall of the main body mechanism 1 is fixedly connected with an adjusting mechanism 3;

[0025] The adjusting mechanism 3 includes a side plate 31. Four groups of sliding grooves 311 are opened on one side of the outer wall of the side plate 31, and four fixing grooves 312 are opened on the outer surface of the side plate 31. The inner walls of the four fixing grooves 312 are all fixedly inserted with cylinders 32. The inner walls of the four groups of sliding grooves 311 are all slidably embedded with slide blocks 33. One side of the outer walls of the four groups of slide blocks 33 is fixedly connected with a U-shaped frame 34. A group of driving rotation grooves 341 are preset inside the four U-shaped frames 34. The inner walls of the four groups of driving rotation grooves 341 are all movably inserted with driving rotation rods 35. The outer surfaces of the four driving rotation rods 35 are all fixedly sleeved with extrusion rollers 36. The tops of the four U-shaped frames 34 are all fixedly connected with linking plates 37, and the telescopic ends of the multiple cylinders 32 are all fixedly connected with the tops of the linking plates 37.

[0026] The effect achieved by the entire Embodiment 1 is as follows. First, when the device is in use, one side of the outer wall of the side plate 31 is fixedly connected to the rotating end of the bearing body 12. When the pipe is placed inside the adjusting mechanism 3, then by relying on the control component, four cylinders 32 can be simultaneously activated. When the four cylinders 32 are in the energized state, their output ends can produce telescopic movement, and with the linkage plate 37 as the linkage medium, the U-shaped frame 34 fixed to the linkage plate 37 can be driven to move inward. During the movement, the four groups of sliders 33 can respectively slide and be embedded in the cooperation of the sliding grooves 311, so that the four pressing rollers 36 can be in contact with the outer wall of the pipe. Then, under the action of an external force, the pipe is pushed forward. When the four driving rods 35 rotate inside the driving grooves 341, the four pressing rollers 36 can rotate on their own, and during the extrusion of the pipe, an effective straightening treatment of the pipe can be completed.

[0027] Embodiment 2, as Figures 2 - 5 shown, the limiting mechanism 2 includes an annular fixed frame 21. Two moving grooves 211 are preset inside the annular fixed frame 21. The inner walls of the two moving grooves 211 are both slidably embedded with moving blocks 22. A regulating frame 23 is fixedly connected between the outer walls of the two moving blocks 22. The main body mechanism 1 includes a main body table 11. A bearing body 12 is fixedly inserted inside the main body table 11. One side of the outer wall of the bearing body 12 is fixedly connected to one side of the outer wall of the side plate 31, and the other side of the outer wall of the bearing body 12 is fixedly connected to one side of the outer wall of the annular fixed frame 21.

[0028] The effect achieved by the entire Embodiment 2 is that when the pipe is being straightened by relying on the adjusting mechanism 3, the limiting mechanism 2 on the other side can perform a limiting treatment on the straightened pipe, effectively limiting the output pipe. During the straightening process, under the action of the bearing body 12, the limiting mechanism 2 and the adjusting mechanism 3 can be rotated to cooperate with the staff to turn and observe the pipe.

[0029] Working principle: When the device is in use, first, fix one side of the outer wall of the side plate 31 to the rotating end of the bearing body 12. Subsequently, place the pipe inside the adjusting mechanism 3. Through the control component, four cylinders 32 can be started simultaneously. When these four cylinders 32 are powered on, their output ends are telescopic. They use the linkage plate 37 as the linkage medium to drive the U-shaped frame 34 fixed to the linkage plate 37 to move inward. During the movement, the four groups of sliders 33 are respectively slidably embedded in the sliding grooves 311 to ensure that the four pressing rollers 36 can keep in contact with the outer wall of the pipe. Then, under the action of an external force, push the pipe forward. The four driving rods 35 rotate inside the driving grooves 341, causing the four pressing rollers 36 to rotate selfingly, and effectively correcting the pipe during the pipe extrusion process. During the process of correcting the pipe relying on the adjusting mechanism 3, the limiting mechanism 2 on the other side can perform a limiting process on the corrected pipe, effectively restricting the position of the output pipe. During the entire correction process, the bearing body 12 enables the limiting mechanism 2 and the adjusting mechanism 3 to rotate, facilitating the staff to flip and observe the pipe.

[0030] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
