Metallurgy rolling mill sleeve shift-out device

Abstract

The invention discloses a metallurgy rolling mill sleeve shift-out device. The metallurgy rolling mill sleeve shift-out device is characterized in that a thrust bearing is added on the outer side of a rotating arm, a pressing device is used for impacting the thrust bearing, and an axial force is applied to the rotating arm through the thrust bearing while a radial direction friction force is simultaneously provided, thereby eliminating the uneven stress applied onto the rotating arm, avoiding the wear on one side in the rotating process, and avoiding the abrasion of the sliding bearing during the rotating process.

Description

technical field [0001] The invention relates to the field of mechanical processing devices, in particular to a sleeve removing device for 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 cau...

Problems solved by technology

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
