[0028] When in use, the flat steel 18 is passed into the vertical roller frame 1, and 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 the flat steel 18 under the drive of the vertical pressing mechanism 4, and the flat steel 18 is straightened in the vertical direction;

[0029] The flat steel 18 passes through the vertical roller frame 1 and 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, horizontally extrude the flat steel 18 to straighten the flat steel 18 in the horizontal direction.

[0030] Example 2

[0031] refer to Figure 2 On the basis of Example 1, it further includes a vertical transmission mechanism 9, which is connected to the plurality of vertical rollers 2 via a rotating shaft.

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

[0033] Example 3

[0034] refer to Figure 1 On the basis of Example 2, it also includes a horizontal transmission mechanism 10, which is transmission-connected to multiple horizontal rollers 6.

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

[0036] Example 4

[0037] refer to Figure 1 On the basis of Example 3, the horizontal transmission mechanism 10 includes a second motor 1001 and a second transmission box 1002 arranged on the upper part of the horizontal roller frame 5, and a plurality of second rotating 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, and multiple second rotating shafts 1003 extend from the lower end of the second transmission box 1002 to transmit power to each horizontal roller 6, so that it rotates during the horizontal straightening process of the flat steel 18 and transmits the flat steel 18 out.

[0039] Example 5

[0040] refer to Figure 3 On the basis of 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 8 is provided with a protruding edge.

[0041] When the horizontal pressure roller 7 and the horizontal roller 8 are horizontally straightening the flat steel 18, the edge on the lower side of the horizontal pressure roller 7 and the edge on the upper side of the horizontal roller 8 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 4On the basis of Example 5, the horizontal pressing mechanism 8 includes: a plurality of horizontal pressing screw rods 11, a nut bearing sleeve 15, a sliding bearing sleeve 16 and a pressure roller shaft 17; the end of each horizontal pressing screw rod 11 is connected to a horizontal bearing seat 12, and a vertical mounting hole 13 is provided on the horizontal bearing seat 12, and an axial adjustment motor 14 is provided at the upper end of the vertical mounting hole 13, and a thread is provided inside the upper end of the vertical mounting hole 13; the nut bearing sleeve 15 is assembled on the inner side of the upper part of the vertical mounting hole 13 through a thread; the sliding bearing sleeve 16 is slidably assembled in the lower port of the horizontal bearing seat 12; the upper end of the pressure roller shaft 17 is rotatably set in the nut bearing sleeve 15, and the lower end of the pressure roller shaft 17 is rotatably set in the sliding bearing sleeve 16, and the pressure roller shaft 17 is connected to the horizontal pressure roller 7.

[0044] Since the horizontal pressure roller 7 and the horizontal roller 8 clamp the flat steel 18 through the lower edge and the upper edge respectively to prevent the edge of the flat steel 18 from being crushed during the straightening process. In order to enable the horizontal pressing mechanism 8 to adapt to the flat steel 18 of different thicknesses, it is necessary to adjust a row of horizontal pressure rollers 7 in the vertical direction. When the axial adjustment motor 14 drives the nut bearing sleeve 15 to rotate, the nut bearing sleeve 15 climbs 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 installed on the pressure roller shaft 17, it also drives the horizontal pressure roller 7 to move up and down, thereby controlling the distance between the lower edge of the horizontal pressure roller 7 and the upper edge of the horizontal roller 6, so as to adapt to the flat steel 18 of different thicknesses.
