In order to make the driving process stable and reliable, the swing arm driving device adopts a linear elevator, the main body of the linear elevator is rotatably connected with the main body 1 of the machine table, and the top of a lifting rod of the linear elevator is rotatably connected with a swing arm 3-1.
The lifting driving device drives the hot roll to ascend, the swinging device drives the second flower roll to contact with the outer peripheral surface of the hot roll, when the hot roll ascends to form an included angle of 30 degrees with the vertical direction of the connecting line of the second flower roll, the first flower roll and the second flower roll in the swinging device are in maximum contact with the hot roll, the material waste in the shutdown time and the shutdown process can be reduced, and the continuous production without shutdown is realized.
When the hot rolling roller 2-1 is at the lowest position, the contact positions of the first embossing roller 4 and the second embossing roller 5 with the hot rolling roller 2-1 are located at the highest point of the outer peripheral surface of the hot rolling roller 2-1, so that the weight of the first embossing roller and the weight of the second embossing roller can be completely applied to the reheating roller, and the running stability of the machine is improved.
When the hot roller 2-1 is at the highest position, the included angle between the connecting line between the contact position of the first embossing roller 4 and the second embossing roller 5 with the hot roller 2-1 and the center of the hot roller 2-1 and the vertical plane is 30 degrees, so that the first embossing roller and the second embossing roller can be simultaneously contacted with the peripheral surface of the hot roller and are not interfered with each other; meanwhile, the required swing distance of the first embossing roller and the second embossing roller is smaller, and the roller changing time is reduced.
The working process of the SY hot rolling mill without stopping and changing the rolls comprises the following steps:
referring to fig. 1, in an initial state, the second patterned roll 5 is in contact with a hot roll 2-1, and the two rolls are in a vertical state;
see fig. 3, roll change first step: the second patterned roll 5 and the hot roll 2-1 rise simultaneously until the connecting line of the two rolls forms an included angle of 30 degrees with the vertical direction;
see fig. 4, roll change second step: the first embossing roll 4 descends to contact the hot rolling roll 2-1, the connecting line of the centers of the three rolls is in an equilateral triangle shape, namely a middle position, and the first embossing roll 4 and the second embossing roll 5 are in contact with the hot rolling roll 2-1 in the middle position state, so that the production continuity can be ensured;
see fig. 5, a third step of roll change: the second embossing roll 5 is separated from the hot rolling roll 2-1;
finally, the first embossing roll 4 and the hot rolling roll 2-1 are lowered simultaneously until the middle point of the two rolls is vertical, see fig. 6.
The SY hot rolling mill capable of changing rolls without stopping in the embodiment drives the hot rolling roll 2-1 to ascend by arranging the lifting driving device, when the hot rolling roll 2-1 ascends to the highest position, the first embossing roll 4 and the second embossing roll 5 can be contacted with the outer peripheral surface of the hot rolling roll 2-1 at the same time, so that continuous production without stopping can be realized when the first embossing roll 4 and the second embossing roll 5 are switched, the stop time and the material waste in the stop process are reduced, and the production cost is greatly saved.
