Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are merely exemplary of the invention and are not intended to be exhaustive. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

After the cold-rolled strip steel is annealed, the cold-rolled strip steel needs to be flattened to obtain a good plate shape and surface appearance. In general, a leveling machine frame subjected to continuous annealing line annealing or bell-type furnace annealing is commonly called a leveling machine in the industry, a single machine frame and a double machine frame are designed according to different leveling processes, and four or six rollers are arranged on a rolling roller system; the flat rack after hot galvanizing annealing furnace is commonly called as a finishing machine in the industry, and mainly adopts a single-rack four-roller mode.

When the galvanizing finisher is rolled, two bearing seats need to be assembled on the working roll body, the purpose of assembling the bearing seats is to play a role in positioning on the one hand, and on the other hand, the working roll body is conveniently pushed and pulled to realize roll replacement, and meanwhile, the bearing seats also need to have a good sealing effect, so that high-pressure cleaning water in the finisher during working is prevented from entering the bearing seats to influence the bearing lubricating effect. The inventor researches and discovers that the design structure of the existing bearing seat, the working roll body and the bearing seat are fixed through the installation of the pressure plate, the pressure plate and the bearing seat are fixed through ten bolts, and the pressure plate is worn or deformed to generate a gap, so that the working roll body moves in the bearing seat, and the normal working state of the working roll is influenced.

In addition, the sealing of the bearing seat adopts a structure similar to a 'bell jar' (commonly known as a head), and the bearing seat is fixed on the bearing seat through six locking bolts. The inventor researches and discovers that the working roll body of the finishing machine needs to be replaced when the specification of rolled strip steel changes or the surface of the working roll body has quality defects. The existing bearing seat is very inconvenient to disassemble and assemble from the working roll body. On the one hand, a pair of working rolls is assembled, four bearing seats are required to be installed, sixty-four bolts are required to be screwed, time is consumed, labor intensity is high, and efficient production cannot be met. Meanwhile, the bolts are frequently disassembled, so that the bolts are damaged by sliding threads or threaded holes, and the hidden danger of assembly quality exists.

Furthermore, the inventor researches and discovers that when the head is assembled, a travelling crane and another operator are required to cooperate, and the labor efficiency is low. And the head needs to be smashed by force by using a tool during disassembly, and the head is detached and deformed by smashing due to frequent operation. The working roll body can lead to fastening bolt to become flexible because of the rolling vibrations of frame in the rolling in-service use of frame, has appeared the production accident that the head falls into the frame many times. Meanwhile, as the bearing seat cavity is designed by adopting aluminum alloy, the threaded hole is very easy to damage, and when the roller in the frame is pulled out, the head is very easy to pull off, so that the roller can not be normally replaced.

In order to solve the above problems, the inventors have developed a hot dip galvanizing finisher work roll and a finisher, and for facilitating understanding of the technical solution of the inventors, the following embodiments are specifically described.
