Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rolling mill production and processing equipment, in particular to the working roll surface of 20 rolling mill roughening treatment device. BACKGROUND

[0002] Because the working roll quantity of 20 rolling mill is more and the diameter is smaller, single working roll processing is time-consuming and laborious, and the working efficiency is low, and the debris generated in the roughening treatment process flies everywhere, and part of the debris adheres to the surface of the working roll that has not been processed, resulting in uneven friction when the debris contacts the grinding disc during subsequent roughening operation, which destroys the roughening effect.

[0003] For example: the working roll surface roughening treatment device of the singermill 20 rolling mill disclosed in the Chinese utility model patent (application number: CN201720824115.1) has the following problems: a large sand throwing machine is used for roughening treatment of the working roll surface of the leveler. The working principle is to use the centrifugal principle to throw steel sand pellets at high speed on the leveler roll surface to make the roll surface present uniform concave-convex points, that is, the leveler roll surface roughening treatment. Usually, the diameter of the leveler is about 500mm, and the sand throwing is placed on the two transmission rubber rollers with a diameter of 300mm. When the sand is thrown, the two transmission rollers drive the leveler to rotate by friction to ensure that the roughened roll surface is uniform and consistent. However, the distance between the two transmission rubber rollers of the existing large sand throwing machine is as wide as 67mm, and the diameter of the working roll of the singermill 20 rolling mill is 35-42mm, so it is impossible to place the working roll of the 20 rolling mill on the two transmission rubber rollers. Therefore, it is impossible to realize sand throwing roughening treatment. The above-mentioned patent can prove the defects of the prior art.

[0004] Therefore, we improve it and propose a working roll surface roughening treatment device for 20 rolling mill. SUMMARY

[0021] 3. Through the cooperation of the limit ring and the clamping gear, the limit ring moves to the front of the limit block and continues to move and then squeezes the limit block. The limit block is pushed to the inside of the movable groove and squeezes the spring. When the limit ring moves completely to the back of the limit block, the limit block loses pressure and rebounds, limiting the limit ring. When the active gear plate drives the clamping gear to rotate, it can drive the working roll assembly to rotate, thereby realizing synchronous texturing of the four working rolls.
