[0053] Reference Fig. 9 and Fig.10 As shown, the plug-in inclined frame 41 includes a snap-in block 411 and an inclined plate 412. The snap-in block 411 is integrally formed and arranged at one end of the inclined plate 412. A back plate 421 is installed on the rear end face of the support bracket 42. The back plate 421 is fixedly connected to the support bracket 42. A plug-in shell 422 is integrally formed on the front end face of the back plate 421.

The plug-in shell 1 422 is integrally formed on the front end face of the back plate 421. The plug-in inclined frames 41 can be spliced ​​with each other through the provision of the plug-in shell 1 422, ensuring that several protective components 4 can be selected for splicing as needed when in use, so as to meet the purpose of supporting a long thin wall. The front end face of the main frame seat 111 is symmetrically provided with a plug-in shell 2 116 for installing the snap-in block 411, and the front end face of the main frame seat 111 is symmetrically provided with a horizontal tube shell 117. The plug-in shell 2 116 and the horizontal tube shell 117 are both fixedly connected to the main frame seat 111. By symmetrically setting the plug-in shell 116 on the front end surface of the main frame seat 111, it is convenient to install by plugging and fixing the plug-in block 411 in the plug-in shell 116 for matching connection, ensuring that it is convenient and quick to disassemble and assemble during use. By symmetrically setting the horizontal tube shell 117 on the front end surface of the main frame seat 111, the size of the horizontal tube shell 117 is larger than the size of the thin-walled pipe fitting 5, ensuring that the horizontal tube shell 117 can achieve a certain protection effect on the thin-walled pipe fitting 5 but does not affect the normal straightening operation of the thin-walled pipe fitting 5.

[0054] Working principle: When actually straightening, first select a number of straightening modules 1 for splicing according to the length and size of the thin-walled pipes 5 to be processed. After the straightening modules 1 are plugged and connected together in sequence, the motor 31 in the shell can be started to drive the threaded rod 32 to rotate, and then the threaded rod 32 is used to drive the movable pressing group 2 to move downward. By adjusting the horizontal height difference between the straightening wheel 23 and the straightening wheel 1 22 on the movable pressing group 2, the thin-walled pipe 5 can be stably clamped up and down for straightening. After the clamping height is determined, the protection component 4 can be assembled. The locking block 411 of the protection component 4 can be inserted into the plug-in shell 116 on the front end face of the main frame seat 111 for quick installation. When the thin-walled pipe 5 is long, multiple groups of protection components 4 can be further spliced ​​at the rear end of the protection component 4. In this way, during the straightening process, the thin-walled pipe 5 can be output to the arc-shaped support plate 43 after passing through the straightening wheels of each straightening module 1 in turn. The arc-shaped support plate 43 can ensure that the thin-walled pipe 5 will not be deformed again after straightening.

Therefore, the present invention is not limited to the above specific implementation modes. Any obvious improvements, substitutions or modifications made by those skilled in the art on the basis of the present invention belong to the protection scope of the present invention.
