Description

TECHNICAL FIELD

[0002] With the continuous development of modern mechanical manufacturing industry, large rollers have become an important part of the steel industry. Large rollers have the advantages of higher hardness, better wear resistance, longer service life, better economic benefit, etc. Generally, large rollers work under cold and hot rolling conditions, and the working surface bears a lot of contact stress, shear stress and periodic bending stress. The surface often appears uneven wear, fatigue cracks, peeling, indentation, peeling off fast, and serious damage such as shoulder dropping and large peeling, which seriously affects production safety and product quality. If not repaired in time, it will cause serious production accidents and make the roller scrap. The replaced waste roller is very easy to rust on the surface and may have quality problems inside. For recycling of large waste rollers, the roller sleeve is generally repaired by inlaying, and the roller surface needs to be derusted and polished before inlaying, and the quality and performance are checked to ensure the quality and performance.

[0003] In actual production workshop, the surface treatment of large waste rollers cannot be derusted and polished comprehensively and effectively, especially for some large rollers with surface quality defects, the surface treatment work needs to be done in advance for flaw detection, and for contact type flaw detection, the surface treatment is mainly to minimize the influence of rust on the roller surface on the internal detection results, and to reduce the wear of the surface contact probe.

When the oil brush 103 moves backward, the rotation is stopped. The entire oil brush device is additionally arranged on four supporting bases 101. The forward and backward movement of the oil brush device is realized by two screws 104 and a base 105 with an internally threaded hole, so as to fix the position. The oil brush device slides forward and backward on the groove table on the four supporting bases 101. The bristles of the oil brush 103 have a certain slope, so that the oil brush 103 is in full contact with the surface of the roller body. A three-section rubber scraper 106 is additionally arranged at the front end of the side in contact with the roller body 11.

Each section of the scraper 106 has a slope at the front end, and a through hole 107 is drilled in the middle, which is in communication with the oil pool 102. When the oil level in the oil pool 102 is higher than the through hole 107, the excess oil will flow into the scraper 106, so as to play a role in supplementing lubrication at the position in contact with the roller body 11. An arc-shaped baffle 108 is additionally arranged on the other side, so as to prevent oil splashing and reduce loss. When the movable oil brusher 10 approaches the groove table on the side of the roller 11, the oil brush is in contact with the roller body 11, and vice versa. The main purpose of the design is to coat oil on the roller body 11 before flaw detection after polishing, so as to facilitate subsequent detection.
