the rolling mill of the utility model can realize automatic roll changing by arranging the roll changing device, and the device is connected with the hydraulic cylinder and the electric control system, so that the roll changing device can quickly and automatically change rolls; the roller changing device has obvious effect, does not need multiple persons to jointly impact, and is safe and convenient. The whole process is free from labor and does not damage the equipment again, the operation is simple and easy, the labor is saved, and the working efficiency is improved.
Drawings
Fig. 1 is a schematic structural diagram of the roll changing device of the rolling mill of the present invention.
Detailed Description
The utility model discloses a rolling mill, including the frame (not shown) and install roll 1, roll chock 2, roll changing device 3 in the frame.
The roller bearing seat 2 is sleeved at the end part of the roller 1, and the edge part is provided with a pin hole 21 along the axial direction;
the roll changing device 3 comprises a roll changing oil cylinder 31, a roll changing pin shaft 33 and an electromagnetic valve 34; the top end of a piston rod of the roll changing oil cylinder 31 is fixedly provided with a connecting piece 32, and the end part of the connecting piece 32 is provided with a through hole which is matched with a pin hole of the roll chock 2;
the roll changing pin shaft 33 passes through the through hole of the connecting piece 32 and is inserted into the pin hole 21 of the roll chock 2, and the connecting piece 32 is fixedly connected with the roll chock 2, so that the roll changing oil cylinder 31 and the roll 1 are connected into a whole;
the electromagnetic valve 34 is connected with a PLC control system of the rolling mill and electrically connected with the roll changing oil cylinder 31, so that the roll changing oil cylinder 31 is controlled, and the purpose of automatic roll changing is achieved.
The utility model discloses automatic roll-changing device's working process:
when roll changing is needed, the PLC control system of the rolling mill controls the electromagnetic valve 34 of the roll changing device 3 to control the roll changing oil cylinder 31 to act, and the roll changing oil cylinder 31 is connected with the roll 1 into a whole through the roll changing pin shaft 33 connecting structure, so that the roll changing oil cylinder 31 acts to drive the roll 1 to be taken out, after the roll 1 is taken out, the roll changing pin shaft 33 is pulled out, the connection between the roll 1 and the roll changing oil cylinder 31 is loosened, and the roll 1 is changed. The whole process is free from labor and does not cause secondary damage to equipment, is simple and easy to implement, saves manpower, improves the working efficiency, and is safe and convenient.
