Pinch roll polishing machine device

Abstract

The invention provides a pinch roll polishing machine device. The pinch roll polishing machine device is composed of a pinch roll polishing device with the same structure and independent upper and lower parts. The pinch roll polishing device comprises a fixed cross beam, a swing arm, a left fixed bracket, a right fixed bracket, a traverse-moving cylinder, a bearing seat part, pressing cylinders, atraverse-moving shaft, a safety locking pin and polishing block parts. During working, the two pressing cylinders drive the swing arm to enable polishing blocks to be tightly attached to the surfaceof a pinch roll, and double-torsion springs on the polishing blocks adjust the direction of the polishing blocks, it is guaranteed that each polishing block can be tangent to the roll surface. After the polishing blocks are pressed on the roll surface, the traverse-moving cylinder drives the polishing blocks to reciprocate in the axial direction of the pinch roll to remove impurities and oxidationiron scales on the roll surface. During the polishing process, cooling water is used for continuously performing flushing to take away the ground impurities, iron pins and the like.

Description

technical field [0001] The invention relates to the technical field of supporting equipment for strip hot continuous rolling, in particular to a pinch roll polisher device. Background technique [0002] At present, with the rapid development of the economy, the supply and demand relationship of hot-rolled thin steel sheets in the automobile and electrical appliance markets has changed. The lightweight production of automobiles requires thinner and thinner steel plates, higher strength and surface quality, and higher production efficiency. The pinch roller polishing machine device has become the first choice for enterprises to solve these problems. The pinch roller polishing machine still relies on imports, and there are no successful cases in China. The most direct impact is that it is expensive, the spare parts cycle is long, and the later operation and maintenance costs are high. [0003] At present, during the field use of the pinch roller polishing machine, the travers...

Problems solved by technology

The pinch roller polishing machine still relies on imports, and there are no successful cases in China. The most direct impact is that it is expensive, the spare parts cycle is long, and the later operation and maintenance costs are high.

[0003] At present, during the field use of the pinch roller polishing machine, the traverse cylinder is subject to vibration for a long time, the working environment is harsh, the service life of the cylinder is low, and the working position is not easy to install and replace; the lateral reciprocating motion of the traverse cylinder is determined by the approaching Switch control, after the cylinder seal is damaged, the control of the cylinder will be affected, if it cannot be found in time, an accident will occur and the surface of the pinch roller will be worn
