Description

Strip steel finish rolling roll changing mechanism Technical Field The utility model relates to the technical field of finish rolling roll replacement, in particular to a strip steel finish rolling roll replacement mechanism. Background The rolling of the strip steel is a core process in the field of metal pressure processing, the metal blank is subjected to plastic deformation by applying pressure to the metal blank through a rolling mill, and finally, the strip steel with uniform thickness, smooth surface and up to the standard mechanical property is obtained, the rolling of the strip steel is a throat link in the steel industry, the technical level of the strip steel directly determines the self-supporting capability of high-end steel in one country, and the strip steel is also an important support for light weight and new energy equipment upgrading of automobiles. In the process of hot rolling the strip steel by the strip steel finishing mill, in order to avoid the surface abrasion and cracking of the roller and the influence on the surface quality of the strip steel product, the defect of strip steel quality is generated, the working roller is required to be replaced after the strip steel finishing mill rolls for a certain tonnage, the existing single roller replacing time is longer, and the improvement of the working efficiency is not facilitated. In view of the above, we propose a strip steel finish rolling roll changing mechanism. Disclosure of Invention The utility model aims to provide a strip steel finish rolling roll changing mechanism, which aims to solve the problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a belted steel finish rolling roll change mechanism, which comprises a roller, one side of roll is equipped with left semi-ring cardboard, and the opposite side of roll is equipped with the connecting axle, the lateral wall fixedly connected with connecting axle of left semi-ring cardboard, and the lateral wall of connecting axle rotates and is connected with the swivel sleeve, the lateral wall of swivel sleeve and the lateral wall fixed connection of right semi-ring cardboard, a plurality of thread grooves have been seted up to the lateral wall of left semi-ring cardboard, and one side of right semi-ring cardboard is equipped with fixing bolt, fixing bolt's one end runs through right semi-ring cardboard and with thread groove threaded connection, and fixing bolt's the other end fixedly connected with presses the piece, press the lateral wall fixedly connected with rotary disk of briquetting, and the surface fixedly connected with U-shaped hook of left semi-ring cardboard and right semi-ring cardboard; when needing to change the roll, can establish left semi-ring cardboard and right semi-ring cardboard cover in the outside of roll, afterwards with fixing bolt and thread groove symmetry, rotate the rotary disk again and drive fixing bolt and thread groove threaded connection, after tightening fixing bolt, press the piece and can offset with right semi-ring cardboard lateral wall, and then connect fixed left semi-ring cardboard and right semi-ring cardboard, later pass U-shaped hook with the loop wheel machine connecting band, can hoist the roll and change work, the change mode is simple, convenient to use is favorable to improving work efficiency.
