[0002] In flat steel finishing lines, flat steel straighteners are used to straighten bends in both directions before feeding the flat steel into subsequent processes. Existing flat steel straighteners primarily straighten vertical bends, while horizontal bends are straightened by changing straightening rollers. As the number of flat steel specifications increases, a new type of horizontal straightening roller needs to be produced for each specification to straighten horizontal bends. This results in a large number of horizontal straightening rollers needing to be prepared and frequently changed, which is time-consuming and labor-intensive. Summary of the Invention

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0026] Example 1

[0027] refer to Figure 1 , Figure 2 and Figure 3 This invention provides a combined roller system flat steel straightening device, comprising: a vertical roller frame 1, multiple vertical pressing mechanisms 4, a horizontal roller frame 5, and multiple horizontal pressing mechanisms 8; a row of vertical rollers 2 is rotatably arranged at the lower part of the interior of the vertical roller frame 1, and a row of vertical pressure rollers 3 is arranged at the upper part of the interior of the vertical roller frame 1, with the vertical pressure rollers 3 and vertical rollers 2 staggered in the vertical direction; multiple vertical pressing mechanisms 4 are arranged at the upper part of the interior of the vertical roller frame 1, and the lower ends of the multiple vertical pressing mechanisms 4 are respectively connected to each A vertical pressure roller 3 is connected to the vertical pressure roller 1, which drives the vertical pressure roller 3 to move up and down. The horizontal roller frame 5 is aligned with the vertical roller frame 1. A row of horizontal rollers 6 is rotatably arranged on one side of the interior of the horizontal roller frame 5, and a row of horizontal pressure rollers 7 is rotatably arranged on the other side of the interior of the horizontal roller frame 5. The horizontal rollers 6 and the horizontal pressure rollers 7 are staggered in the horizontal direction. Multiple horizontal pressing mechanisms 8 are arranged on one side of the interior of the horizontal roller frame 5. The multiple horizontal pressing mechanisms 8 are respectively connected to each horizontal pressure roller 7, which drives the horizontal pressure roller 7 to move laterally.

[0028] In use, the flat steel 18 is passed into the vertical roller frame 1. The flat steel 18 passes between a row of vertical rollers 2 and a row of vertical pressure rollers 3. The row of vertical pressure rollers 3 presses down on the flat steel 18 under the drive of the vertical pressing mechanism 4, and straightens the flat steel 18 in the vertical direction.

[0029] After passing through the vertical roller frame 1, the flat steel 18 enters the horizontal roller frame 5. The flat steel 18 passes between a row of horizontal rollers 6 and a row of horizontal pressure rollers 7. The row of horizontal pressure rollers 7, driven by the horizontal pressing mechanism 8, performs horizontal extrusion on the flat steel 18 and straightens the flat steel 18 in the horizontal direction.

[0030] Example 2

[0031] refer to Figure 2 Based on Embodiment 1, it also includes a vertical transmission mechanism 9, which is connected to multiple vertical rollers 2 via a rotating shaft.

[0032] Both vertical roller 2 and vertical pressure roller 3 are active rollers. The vertical transmission mechanism 9 includes a first motor 901 connected to a first transmission box 902. Multiple first transmission shafts 903 extend from the other side of the first transmission box 902 to drive the rotation of each vertical roller 2 and vertical pressure roller 3. The vertical pressing mechanism 4 adjusts the opening degree of the vertical pressure roller 3.

[0033] Example 3

[0034] refer to Figure 1 Based on embodiment 2, it also includes a horizontal transmission mechanism 10, which is connected to multiple horizontal rollers 6 in a transmission manner.

[0035] When straightening flat steel, the horizontal transmission mechanism 10 drives multiple horizontal rollers 6 to rotate. In the direction of travel of flat steel 18, the horizontal rollers 6 are the driving rollers and the horizontal pressure rollers 7 are the driven rollers.

[0036] Example 4

[0037] refer to Figure 1 Based on embodiment 3, the horizontal transmission mechanism 10 includes a second motor 1001 and a second transmission box 1002 disposed on the upper part of the horizontal roller frame 5. Multiple second transmission shafts 1003 extend from the lower end of the second transmission box 1002 and are connected to each horizontal roller 6.

[0038] The main shaft of the second motor 1001 extends into the second transmission box 1002 to transmit power. Multiple second transmission shafts 1003 extend from the lower end of the second transmission box 1002 to transmit power to each horizontal roller 6, causing it to rotate during the horizontal straightening of the flat steel 18 and transmit the flat steel 18 out.

[0039] Example 5

[0040] refer to Figure 3 Based on Example 1, the lower side of the horizontal pressure roller 7 is provided with a protruding edge, and the upper side of the horizontal roller 6 is provided with a protruding edge.

[0041] When the horizontal pressure roller 7 and the horizontal roller 6 are used to horizontally straighten the flat steel 18, the lower edge of the horizontal pressure roller 7 and the upper edge of the horizontal roller 6 can prevent the edge of the flat steel 18 from being crushed during the straightening process.

[0042] Example 6

[0043] refer to Figure 2 and Figure 4 Based on embodiment 5, the horizontal pressing mechanism 8 includes: multiple horizontal pressing screws 11, nut bearing sleeves 15, sliding bearing sleeves 16, and pressure roller shafts 17; each horizontal pressing screw 11 has a horizontal bearing seat 12 connected to its end, the horizontal bearing seat 12 has a vertical mounting hole 13, the upper end of the vertical mounting hole 13 has an axial adjustment motor 14, and the upper end of the vertical mounting hole 13 has a thread; the nut bearing sleeve 15 is threadedly fitted to the inner side of the upper part of the vertical mounting hole 13; the sliding bearing sleeve 16 is slidably fitted into the lower port of the horizontal bearing seat 12; the upper end of the pressure roller shaft 17 is rotatably disposed in the nut bearing sleeve 15, the lower end of the pressure roller shaft 17 is rotatably disposed in the sliding bearing sleeve 16, and a horizontal pressure roller 7 is connected to the pressure roller shaft 17.

[0044] Because the horizontal pressure rollers 7 and 6 clamp the flat steel 18 through their lower and upper edges respectively, preventing the edges of the flat steel 18 from being crushed during the straightening process. In order to enable the horizontal pressing mechanism 8 to adapt to flat steel 18 of different thicknesses, it is necessary to adjust the vertical direction of a row of horizontal pressure rollers 7. When the axial adjustment motor 14 drives the nut bearing sleeve 15 to rotate, the nut bearing sleeve 15 moves up and down in the vertical mounting hole 13 of the horizontal bearing seat 12, thereby driving the pressure roller shaft 17 and the sliding bearing sleeve 16 to slide up and down in the vertical mounting hole 13. Since the horizontal pressure roller 7 is mounted on the pressure roller shaft 17, it also drives the horizontal pressure roller 7 to move up and down. In this way, the distance between the lower edge of the horizontal pressure roller 7 and the upper edge of the horizontal roller 6 can be controlled to adapt to flat steel 18 of different thicknesses.
