Therefore, when the mounting seat and the rotating rollers synchronously approach the U-shaped metal plate, only the rotating rollers will contact the U-shaped metal plate, thereby facilitating the discharge of the U-shaped metal plate.

[0026] Example 2

[0027] Reference Figure 1-4, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a plurality of bottom correction rollers 12 located below the second mounting seat 32 are rotatably installed between the two opposite inner cavity walls of the correction cavity 11, and a driving motor is hidden in the machine base 1. The output end of the driving motor drives the bottom correction roller 12 on the outermost side to rotate, and the rolling friction resistance between the bottom correction roller 12 and the U-shaped metal plate enables the U-shaped metal plate to be corrected while discharging the material; the side extrusion assembly 2 also includes a telescopic cylinder 21 fixedly installed on the outer wall of the machine base 1, and the output ends of the telescopic cylinder 21 are connected to a telescopic rod 22 extending through the correction cavity 11 and fixedly installed on the back side of the corresponding first mounting seat 23. The bottom correction assembly also includes a lifting column 31 installed on the top of the second mounting seat 32, and two first racks 34 are installed on both sides of the lifting column 31, and the first rack 34 is meshed with one side to install the first rack Wheel 35, the second gear 37 is installed on the opposite side of the two first gears 35, and the bottom ends of the two second gears 37 are meshed with the second rack 38. In the utility model, a total of four first racks 34, four first gears 35, two second gears 37 and two second racks 38 are provided. The two second racks 38 are vertically fixedly installed on the back side of the corresponding third mounting seat 39 at one end away from the lifting column 31. The lifting cylinder 3 is fixedly installed at the top center of the base 1. The output end of the lifting cylinder 3 extends through the correction cavity 11 and is fixedly installed on the top of the lifting column 31. A plurality of L-shaped support rods 36 are installed on the upper cavity top of the correction cavity 11. The first gears 35 are rotatably installed at the ends of the corresponding L-shaped support rods 36 to ensure that the four first gears 35 rotate stably. The two opposite outer walls of the lifting column 31 are vertically fixedly installed with limit seats, and the two second racks 38 are respectively slidably installed with the corresponding limit seats. Figure 4 It can be known that the two opposite outer side walls of the second rack 38 are provided with sliding grooves adapted to the limit seat, so that the movement of the second rack 38, the third mounting seat 39 and the plurality of third rotating rollers 310 can be stable and reliable.

[0028] The remaining structures are the same as those of Example 1.

[0029] First, the U-shaped metal plate to be corrected is placed on top of a plurality of bottom correction rollers 12 in the correction chamber 11, and the two side plates of the U-shaped metal plate are respectively located between the corresponding first mounting seat 23 and the third mounting seat 39;

[0030] Secondly, the lifting cylinder 3 is started, and the second mounting seat 32 is driven to descend in height through the lifting column 31 until the second rotating rollers 33 at the bottom of the second mounting seat 32 contact the upper surface of the U-shaped metal plate. At the same time, the lifting column 31 descends and drives the two first racks 34 on both sides to descend synchronously, and then meshes and drives the first gear 35 to rotate. The first gear 35 is fixedly installed with the second gear 37, thus driving the second gear 37 to rotate synchronously. The second gear 37 meshes and drives the second rack 38 to slide synchronously, and finally pushes the corresponding third mounting seats 39 respectively, so that the third rotating rollers 310 are pressed and contacted on the two opposite inner walls of the U-shaped metal plate.

[0031] Finally, start the two telescopic cylinders 21, and push the corresponding first mounting seats 23 close to the U-shaped metal plate through the telescopic rods 22 until the first rotating rollers 24 collide with the two opposite outer walls of the U-shaped metal plate. At this time, start the driving motor installed in the machine base to drive the bottom correction roller 12 on the edge to rotate, and drive the U-shaped metal plate through the rolling friction resistance between the bottom correction roller 12 and the U-shaped metal plate through the correction cavity 11. Both sides and the bottom of the U-shaped metal plate are corrected at the same time, which has the advantages of high correction efficiency and a wide range of applications.
