[0042] The present utility model provides a straightening machine 100, which can be used to straighten long steel billets. Specifically, please refer to Figure 1 and Figure 2 , in this embodiment, the straightening machine 100 includes a frame 1, a first straightening assembly 2 and a second straightening assembly 3; the first straightening assembly 2 includes a first straightening structure 21 and a second straightening structure 22 that are spaced apart in the up and down direction of the frame 1, and the interval between the first straightening structure 21 and the second straightening structure 22 forms a straightening area; the second straightening assembly 3 includes a third straightening structure 31 and a fourth straightening structure 32 that are spaced apart in the transverse direction of the frame 1, and the third straightening structure 31 and the fourth straightening structure 32 are located on both sides of the straightening area in the transverse direction of the frame 1.

[0043] In this embodiment, by forming a straightening area in the interval between the first straightening structure 21 and the second straightening structure 22, the straightening area can accommodate a single steel billet, and the steel billet is straightened in the up and down direction of the frame 1 by the first straightening structure 21 and the second straightening structure; moreover, the second straightening assembly 3 includes a third straightening structure 31 and a fourth straightening structure 32 that are spaced apart in the transverse direction of the frame 1, and the third straightening structure 31 and the fourth straightening structure 32 are located on both sides of the straightening area in the transverse direction of the frame 1. The steel billet accommodated in the straightening area can be straightened in the transverse direction of the frame 1 by the third straightening structure 31 and the fourth straightening structure 32, so that the steel billet can be pressed and straightened in multiple directions, which can better ensure the straightness of the steel billet and has a higher straightening efficiency.

[0044] It should be noted that when the straightening machine 100 is operating normally, the pressing directions of the first straightening assembly 2 and the second straightening assembly 3 are perpendicular to the length direction of the billet. Among them, the lateral direction may refer to the left-right direction along the frame 1, then the billet can enter the straightening area along the front-back direction of the frame 1, and the length direction of the billet extends along the front-back direction of the frame 1. The descriptions of the orientations in the present utility model can all be referred to based on this.

[0045] Among them, as Figure 1 shown in the figure, the first straightening structure 21 is located below the second straightening structure 22. It can be understood that at least one of the first straightening structure 21 and the second straightening structure 22 is arranged movably, so as to adjust the size of the straightening area, so as to be suitable for the straightening requirements of billets of various different sizes.

[0046] Preferably, the second straightening structure 22 is movably arranged on the frame 1 to be able to approach and move away from the first straightening structure 21. Specifically, as Figure 1 shown in the figure, the first straightening structure 21 includes a first straightening roller 211 rotatably arranged on the frame 1 and a first straightening driver 212 drivingly connected to the first straightening roller 211. After the billet arrives, it can be placed on the first straightening roller 211, and by driving the first straightening roller 211 to rotate through the first straightening driver 212, the billet can be driven, so that the billet can enter from the feeding end of the straightening area and output from the discharging end of the straightening area.

[0047] Combined with Figure 1 and Figure 4 shown in the figure, the second straightening structure 22 includes a second straightening roller 221 and a first adjustment driving member 222. The second straightening roller 221 has a moving stroke of approaching and moving away from the first straightening roller 211, and the first adjustment driving member 222 is used to drive the second straightening roller 221 to approach or move away from the first straightening roller 211. By driving the second straightening roller 221 to approach the first straightening roller 211 through the first adjustment driving member 222, the first straightening roller 211 and the second straightening roller 221 can respectively press on both sides of the billet in the up-down direction along the frame 1 to straighten the billet, and by the rotation of the first straightening roller 211, the billet can be conveyed and drive the second straightening roller 221 to rotate together, so that all parts of the billet along its length direction can be straightened, and the straightening is more uniform, so the straightening effect is better.

[0048] Furthermore, as Figure 4As shown in the figure, the first adjustment driving component 222 includes an adjustment support 2221, an adjustment hydraulic cylinder 2222 and an adjustment block 2223. The adjustment support 2221 is arranged on the frame 1. The adjustment hydraulic cylinder 2222 includes a hydraulic cylinder main body 2222a rotatably arranged on the adjustment support 2221 and a telescopic rod 2222b telescopically arranged on the hydraulic cylinder main body 2222a. One side of the adjustment block 2223 is hinged to the telescopic rod 2222b, and the other side is hinged to the adjustment support 2221. The second straightening roller 221 is arranged on the adjustment block 2223. When the telescopic rod 2222b is in a contracted state, the second straightening roller 221 is in a first position away from the first straightening roller 211. When the telescopic rod 2222b is in an extended state, the second straightening roller 221 is in a second position close to the first straightening roller 211. The adjustment is convenient and flexible, and the structure is compact, occupying a small space.

[0049] Specifically, the adjustment block 2223 is generally trapezoidally arranged. The short side side wall of the trapezoid is hinged to the telescopic rod 2222b, and the inclined side wall of the trapezoid is hinged to the adjustment support 2221. The second straightening roller 221 is rotatably arranged on the long side side wall of the trapezoid, so that while the moving stroke in the longitudinal direction of the frame 1 can be shorter, the lifting of the second straightening roller 221 can be better realized, making the structure of the entire straightening machine 100 more compact and occupying less space.

[0050] For the second straightening assembly 3, in combination with Figure 2 and Figure 3As shown, the third straightening structure 31 includes a first mounting plate 311, and a third straightening roller 312 rotatably mounted on the first mounting plate 311; the fourth straightening structure 32 includes a second mounting plate 321, a fourth straightening roller 322 rotatably mounted on the second mounting plate 321, and a second straightening driver 323 drivingly connected to the fourth straightening roller 322; the second straightening assembly 3 also includes a second adjusting driving component 33 connecting the third straightening roller 312 and the fourth straightening roller 322, and the second adjusting driving component 33 can drive the third straightening roller 312 and the fourth straightening roller 322 to move closer to and away from each other. The fourth straightening roller 322 is driven to rotate by the second straightening driver 323, so that the fourth straightening roller 322 can actively rotate to form a transmission force on the steel billet, so that the steel billet can be transmitted. Furthermore, the third straightening roller 312 and the fourth straightening roller 322 can be driven to move relative to each other through the second adjustment drive component 33, so that the distance between the third straightening roller 312 and the fourth straightening roller 322 can be adjusted, so that when the third straightening roller 312 and the fourth straightening roller 322 are close to each other, they can be pressed against the two sides of the steel billet along the horizontal direction of the frame 1, so as to straighten the steel billet; when the third straightening roller 312 and the fourth straightening roller 322 are away from each other, a clearance space is formed, so that the external steel billet can better enter the straightening area for straightening.

[0051] Preferably, if Figure 2 As shown in , the second adjustment driving component 33 includes an adjustment screw 331 and an adjustment nut 332. The adjustment screw 331 is arranged to extend in the lateral direction of the frame 1, and the two ends of the adjustment screw 331 are respectively connected to the first mounting plate 311 and the second mounting plate 321; the adjustment nut 332 is screwed on the adjustment screw 331, and adjusting the adjustment nut 332 can drive the first mounting plate 311 and the second mounting plate 321 to move closer to or farther from each other. The adjustment nut 332 can be driven by a driver, or the adjustment nut 332 can also be adjusted manually. The movement of the third straightening roller 312 and the fourth straightening roller 322 can be adjusted simultaneously by the adjustment nut 332, so that the synchronization is better, and the movement method is also simpler.

[0052] It can be understood that, in one embodiment, the first mounting plate 311 and the second mounting plate 321 can be translated so as to both have a translation stroke along the lateral direction of the frame 1 .

[0053] Preferably, one end of the first mounting plate 311 in the longitudinal direction is rotatably arranged on the frame 1, and the other end of the first mounting plate 311 in the longitudinal direction is hinged to the adjusting screw 331; one end of the second mounting plate 321 in the longitudinal direction is rotatably arranged on the frame 1, and the other end of the second mounting plate 321 in the longitudinal direction is hinged to the adjusting screw 331. By rotating the first mounting plate 311, the third straightening roller 312 is caused to move in the transverse direction of the frame 1, and by rotating the second mounting plate 321, the fourth straightening roller 322 is caused to move in the transverse direction of the frame 1. The driving structure is simpler and requires less moving space.

[0054] Moreover, the second straightening assembly 3 further includes an adjusting and limiting structure 34, which is used to adjust and limit the distances of the third straightening roller 312 and the fourth straightening roller 322 from the center of the straightening area to be equal, so as to better ensure that the pressing amounts are more consistent when the third straightening roller 312 and the fourth straightening roller 322 are pressed against the steel billet, and thus better ensure the straightening effect.

[0055] Preferably, as Figure 2 shown in, the adjusting and limiting structure 34 includes a first toothed plate 341 and a second toothed plate 342 which are arranged in relative meshing. The first toothed plate 341 is coaxially connected to the first mounting plate 311, and the rotation of the first mounting plate 311 drives the first toothed plate 341 to rotate together. The second toothed plate 342 is coaxially connected to the second mounting plate 321, and the rotation of the second mounting plate 321 drives the second toothed plate 342 to rotate together. The first toothed plate 341 and the second toothed plate 342 mesh with each other, and thus abut against each other at the meshing position to ensure the relative position of the rotation position of the first toothed plate 341 and the rotation position of the second toothed plate 342 is fixed, which can ensure that the rotation speeds of the first mounting plate 311 and the second mounting plate 321 are consistent during rotation, and the displacement amounts of the relative movement of the third straightening roller 312 and the fourth straightening roller 322 are consistent. Therefore, when pressed against the outer side of the steel billet, the pressing amounts of the third straightening roller 312 and the fourth straightening roller 322 are consistent, and the pressing effects on both sides of the steel billet are consistent, so the straightening effect is better.

[0056] Furthermore, both the first toothed plate 341 and the second toothed plate 342 are fan-shaped and are oppositely arranged on both sides of the straightening area in the transverse direction of the frame 1. Since the movement amounts of the third straightening roller 312 and the fourth straightening roller 322 are relatively small, the meshing and rotation angles of the first toothed plate 341 and the second toothed plate 342 are also relatively small. Setting both the first toothed plate 341 and the second toothed plate 342 as fan-shaped occupies less space.

[0057] Moreover, multiple groups of the first straightening components 2 are provided, and the multiple groups of the first straightening components 2 are arranged at intervals along the longitudinal direction of the frame 1. The multiple groups of the first straightening components 2 can act on multiple positions of the billet in the up-and-down direction simultaneously, and the straightening efficiency is higher. Similarly, multiple groups of the second straightening components 3 are provided, and the multiple groups of the second straightening components 3 are arranged at intervals along the longitudinal direction of the frame 1. The multiple groups of the first straightening components 2 can act on multiple positions of the billet in the transverse direction simultaneously, and the straightening efficiency is higher. Moreover, the multiple groups of the first straightening components 2 and the multiple groups of the second straightening components 3 are arranged in an alternating and spaced manner in sequence to avoid collisions.

[0058] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structures made by using the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
