Metallurgical rolling mill

Abstract

The invention discloses a metallurgical rolling mill. A thrust bearing is additionally arranged on the outer side of a rotating arm of a sleeve move-out device of the metallurgical rolling mill and is tightly pressed by a pressing device. The thrust bearing applies axial force and supplies radial friction to the rotating arm simultaneously, so that the stress unbalance of the rotating arm can be eliminated. Therefore, a sliding bearing can be prevented from being worn due to unilateral frication generated in a rotating process.

Description

technical field [0001] The invention relates to the field of mechanical processing devices, in particular to a metallurgical rolling mill. Background technique [0002] Metallurgical rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment and auxiliary equipment. During the rolling process, the sleeve needs to be transported from the side of the uncoiler to the side of the coiler. At present, the rotating pair in the sleeve removal device of the metallurgical rolling mill adopts the form of a sliding bearing. Please refer to figure 1 , that is, the rotating arm 2 is connected to the pin shaft 1 through the sliding bearing 3. The characteristic of the sliding bearing 3 cannot bear the axial force. In the case of uneven radial force, it is easy to cause unilateral wear of the sli...

During the rolling process, the sleeve needs to be transported from the side of the uncoiler to the side of the coiler. At present, the rotating pair in the sleeve removal device of the metallurgical rolling mill adopts the form of a sliding bearing. Please refer to figure 1 , that is, the rotating arm 2 is connected to the pin shaft 1 through the sliding bearing 3. The characteristic of the sliding bearing 3 cannot bear the axial force. In the case of uneven radial force, it is easy to cause unilateral wear of the sliding bearing 3, and then damage the pin shaft. 1 and swivel arm 2

Replacing pin shaft 1 and sliding bearing 3 is time-consuming and laborious, affecting production
