[0039] Working principle: The device can adjust the positions of the first rolling mill 404, the second rolling mill 405, and the third rolling mill 406 according to the length of the special-shaped steel, further accurately control the rolling length of the end of the special-shaped steel, and improve the utilization rate of the device; the device can roll two special-shaped steels simultaneously, saving manpower; the device can roll the two ends of the special-shaped steel synchronously, reducing the rolling steps of the special-shaped steel, reducing the working time, and effectively improving the economic benefits; the device can perform rough rolling and fine rolling on the ends of the special-shaped steel respectively to meet different requirements and effectively improve the working efficiency;

[0040] When performing the rolling work of special-shaped steel, it is first necessary to adjust the clamping position according to the length of the special-shaped steel. At this time, the motor Ⅰ 110 starts, driving the gear set 109 to rotate. The gear set 109 drives the two cams 108 to rotate respectively, and 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, adjusting the position of the electric clamps 106 to adapt to the clamping of special-shaped steel with different lengths, ensuring the clamping effect and preventing the special-shaped steel from moving during the rolling process;

[0041] Then, when adjusting the position of the support frame Ⅲ 403 according to the length of the special-shaped steel, the lead screw slider group 402 works, driving the support frame Ⅲ 403 to move, adjusting the position of the support frame Ⅲ 403, and further realizing the position adjustment of the first rolling mill 404, the second rolling mill 405, and the third rolling mill 406, further accurately determining the rolling length of the end of the special-shaped steel;

[0042] Then, place the two special-shaped steels on the two groups of electric clamps 106 respectively. The electric clamps 106 clamp the special-shaped steel. At this time, the cross bar 102 is at the lowest point, and the special-shaped steel clamped by the electric clamps 106 is aligned with the first rolling mill 404. The first rolling mill 404 works. Then, when the two special-shaped steels are simultaneously moved to both sides for rolling the ends of the special-shaped steel, the motor Ⅲ 207 starts, driving the large disc 203 to rotate. The large disc 203 drives the gear Ⅲ 206 to rotate forward. The gear Ⅲ 206 drives the gear Ⅱ 205 to rotate forward. The gear Ⅱ 205 drives the two racks 105 to move outward simultaneously. The two racks 105 drive the two cross plates 104 to move outward simultaneously. The two cross plates 104 drive the two groups of electric clamps 106 clamping the special-shaped steel to move outward simultaneously, so that the outer ends of the two special-shaped steels are simultaneously moved into the two corresponding first rolling mills 404 for rough rolling of the upper and lower sides of the special-shaped steel. Then, when the large disc 203 rotates to the teeth on its inner ring not meshing with the gear Ⅲ 206, the large disc 203 drives the teeth on the gear Ⅰ 204 to mesh with the gear Ⅲ 206. At this time, the gear Ⅰ 204 drives the gear Ⅲ 206 to rotate reversely. The gear Ⅲ 206 drives the gear Ⅱ 205 to rotate reversely. The gear Ⅱ 205 drives the two racks 105 to move reversely simultaneously. The two racks 105 drive the two cross plates 104 to move reversely and return to their original positions. At this time, one end of the two special-shaped steels is completed with rough rolling on the upper and lower sides;

[0043] Then, Motor III 207 operates in reverse, driving the large disc 203 to rotate in reverse. The large disc 203 drives Gear III 206 to rotate in reverse, Gear III 206 drives Gear II 205 to rotate in reverse, and Gear II 205 drives the two racks 105 to move outward relative to the previous position in the reverse direction simultaneously. The two racks 105 respectively drive the two cross plates 104 to move outward relative to the previous position in the reverse direction simultaneously. The two cross plates 104 simultaneously drive the two groups of electric clamps 106 to clamp the special-shaped steel and move outward relative to the previous position in the reverse direction, so that the unrolled outer ends of the two special-shaped steels are simultaneously moved into the two corresponding first rolling mills 404, and rough rolling is performed on the upper and lower sides of the special-shaped steel. Then, when the teeth on the inner ring of the large disc 203 do not mesh with Gear III 206, the large disc 203 drives the teeth on Gear I 204 to mesh with Gear III 206. At this time, Gear I 204 drives Gear III 206 to rotate in reverse, Gear III 206 drives Gear II 205 to rotate in reverse, Gear II 205 drives the two racks 105 to move back to their original positions in the reverse direction simultaneously, and the two racks 105 respectively drive the two cross plates 104 to move back to their original positions in the reverse direction. At this time, rough rolling is completed on the upper and lower sides of both ends of the two special-shaped steels;

[0044] When rough rolling is performed on both sides of both ends of the special-shaped steel, Motor II 303 starts, driving the round rod 304 to rotate 90°. The round rod 304 drives the two auxiliary discs 305 to rotate 90°. The two auxiliary discs 305 respectively drive the two cross bars 102 to move upward simultaneously, so that the cross bars 102 are in the centered position. At this time, the special-shaped steel clamped by the electric clamps 106 is aligned with the second rolling mill 405. The second rolling mill 405 operates. At this time, Motor III 207 operates again to repeat the above steps, sending the two special-shaped steels into the second rolling mill 405 respectively, so as to perform rough rolling on the left and right sides of the ends of the special-shaped steel;

[0045] When finish rolling is performed on both sides of both ends of the special-shaped steel, Motor II 303 starts again, driving the round rod 304 to rotate 90°. The round rod 304 drives the two auxiliary discs 305 to rotate 90°. The two auxiliary discs 305 respectively drive the two cross bars 102 to move upward simultaneously, so that the cross bars 102 are in the highest position. At this time, the special-shaped steel clamped by the electric clamps 106 is aligned with the third rolling mill 406. The third rolling mill 406 operates. At this time, Motor III 207 operates again to repeat the above steps, sending the two special-shaped steels into the third rolling mill 406 respectively, so as to perform finish rolling on the ends of the special-shaped steel.
