At this time, the motor I 110 is started to drive the gear set 109 to rotate, and the gear set 109 drives the two cams 108 to rotate respectively. The two cams 108 drive the two vertical rods 107 to move left and right respectively. The two vertical rods 107 drive the two electric clamps 106 to move left and right. The position of the electric clamps 106 is adjusted to adapt to the clamping of special-shaped steels of different lengths, ensure the clamping effect, and prevent the special-shaped steel from moving during the rolling process. Then, when the position of the support frame III 403 is adjusted according to the length of the special-shaped steel, the lead screw slider group 402 works to drive the support frame III 403 to move, and the position of the support frame III 403 is adjusted, thereby realizing the position adjustment of the first rolling mill 404, the second rolling mill 405, and the third rolling mill 406, and further accurately adjusting the rolling length of the end of the special-shaped steel; Then, the two special-shaped steels are placed on the two sets of electric clamps 106 respectively, and the electric clamps 106 clamp the special-shaped steels.

Then, when the large disc 203 rotates to the point where the gear teeth on its inner ring are not meshed with the gear III 206, the large disc 203 drives the gear teeth on the gear I 204 to mesh with the gear III 206.

The gear II 205 drives the two racks 105 to move in the opposite direction and return to their positions at the same time. The two racks 105 drive the two cross plates 104 to move in the opposite direction and return to their positions. At this time, rough rolling on the upper and lower sides of the two special-shaped steels is completed. When rough rolling is performed on both ends of the special-shaped steel, the motor II 303 is started, driving the round rod 304 to rotate 90°, and the round rod 304 drives the two auxiliary disks 305 to rotate 90°. The two auxiliary disks 305 respectively drive the two cross bars 102 to move upward at the same time, so that the cross bars 102 are located in the middle position. At this time, the special-shaped steel clamped by the electric clamp 106 is aligned with the second rolling mill 405, and the second rolling mill 405 works. At this time, the motor III 207 works again to repeat the above steps, and the two special-shaped steels are respectively sent into the second rolling mill 405, so that the ends of the special-shaped steel are rough rolled on the left and right sides; When fine rolling is performed on the two ends of the special-shaped steel, the motor II 303 is started again, driving the round rod 304 to rotate 90°, and the round rod 304 drives the two auxiliary disks 305 to rotate 90°. The two auxiliary disks 305 respectively and simultaneously drive the two cross bars 102 to move upward so that the cross bars 102 are located at the highest position. At this time, the special-shaped steel clamped by the electric clamp 106 is aligned with the third rolling mill 406, and the third rolling mill 406 works. At this time, the motor III 207 works again to repeat the above steps, and the two special-shaped steels are respectively sent into the third rolling mill 406 to perform fine rolling on the ends of the special-shaped steel.
