After the round steel 211 passes through the straightening mechanism 2 completely, the straightness of the round steel 211 is significantly improved, meeting the requirements of subsequent processing or use. Then, the straightened round steel 211 slides out from the other end of the connecting pipe 202 and enters the transmission and smoothing mechanism 4 for further processing.

[0023] Further, the position of the limiting block 207 corresponds to the position of the limiting groove 205, and the outer wall size of the limiting block 207 matches the inner wall size of the limiting groove 205. Through the arrangement of the limiting groove 205 and the limiting block 207, the movement track of the extension rod 206 in the extension groove 204 is accurate and stable. The accurate corresponding position and the matched size make the limiting block 207 slide smoothly in the limiting groove 205, preventing the extension rod 206 from tilting, shaking or rotating during the extension process. When the round steel 211 contacts the straightening roller 210 and generates a lateral force, the extension rod 206 can strictly extend in a straight line, ensuring that the reaction force generated by the extension spring 208 can be accurately transmitted to the straightening roller 210 through the connecting plate 209, thereby effectively correcting the bent part of the round steel 211 and improving the straightening precision and stability.

[0024] Further, the extension assembly composed of the fixed rod 203, the extension rod 206 and the extension spring 208 is symmetrically provided with four identical groups on the surface of the support body 201. Each group of extension assemblies corresponds to the connecting plate 209 and the straightening roller 210, which cooperate to straighten the round steel 211. Through the arrangement of the fixed rod 203, the extension rod 206, the extension spring 208, the connecting plate 209 and the straightening roller 210, the round steel 211 is straightened in all directions and at multiple angles. The four groups of symmetrically distributed extension assemblies can simultaneously apply straightening force to the round steel 211 from different directions, effectively correcting the bending of the round steel 211 in all directions. The elastic action of the extension spring 208 enables the straightening roller 210 to automatically adjust the pressure according to the actual bending condition of the round steel 211, ensuring the flexibility and adaptability of the straightening process and improving the straightening quality of the round steel 211 to a higher standard.

[0025] Further, the driving motor 402 and the driving wheel 403 cooperate to form a rotating structure, the track 404 drives the driven wheel 405 to rotate through the driving wheel 403, and through the driving motor 402, the driving wheel 403, the track 404 and the driven wheel 405, the efficient transmission and stable output of power are realized, the driving motor 402 provides power for the entire transmission system, drives the driving wheel 403 to rotate, and the driving wheel 403 transmits the rotating power to the driven wheel 405 through the close fit with the track 404, so that the driven wheel 405 rotates synchronously. This power transmission through the track 404 has the advantages of stable transmission, low noise and shock absorption, which ensures the stability and accuracy of the rotation of the driven wheel 405 and provides reliable power support for the subsequent transmission roller 407 to drive the round steel 211.

[0026] Further, the rotating shaft 406 and the transmission roller 407 are arranged on the inner side of the base 1 in the same two groups, and the two groups of transmission rollers 407 cooperate with each other to drive and axially move the workpiece. Through the arrangement of the rotating shaft 406 and the transmission roller 407, the stable transmission and accurate conveying of the round steel 211 are realized. The two groups of transmission rollers 407 are arranged oppositely. When the driven wheel 405 drives the rotating shaft 406 to rotate, the transmission roller 407 on the rotating shaft 406 rotates. The round steel 211 is placed between the two groups of transmission rollers 407. The transmission roller 407 contacts the surface of the round steel 211 and drives the round steel 211 to move axially through friction, so that it can be smoothly conveyed from the straightening mechanism 2 to the calendering area, ensuring the continuity and smoothness of the processing process and improving the processing efficiency.

[0027] Further, the hydraulic rod 410 and the hydraulic cylinder 409 cooperate to form an extension structure, and the connecting seat 411 drives the calendering wheel 412 to press down to calender the workpiece through the hydraulic rod 410. Through the arrangement of the hydraulic cylinder 409, the hydraulic rod 410, the connecting seat 411 and the calendering wheel 412, the accurate control of the calendering process of the round steel 211 is realized. The hydraulic cylinder 409 can accurately control the extension length and pressure of the hydraulic rod 410 according to the material, diameter of the round steel 211 and the required calendering effect. The extension of the hydraulic rod 410 drives the connecting seat 411 and the calendering wheel 412 to move up and down, so that the calendering wheel 412 can accurately contact the surface of the round steel 211 and apply appropriate pressure for calendering treatment. This accurate control ensures the consistency and stability of the calendering quality of the surface of the round steel 211, effectively removes the tiny defects on the surface of the round steel 211, and improves the surface finish and quality.
