Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a centrifugal composite roller with a sleeve that is convenient for replacing. Background Art

[0002] Centrifugal composite rollers are the main working consumables of rolling mills and have a direct impact on product quality and work efficiency. The existing rolling mill rollers are not rigid enough and hard enough. During the operation, the surfaces of the centrifugal composite rollers are prone to bending and deformation, which seriously affects the quality of the rolled material and the service life of the rollers.

[0003] If the rollers are replaced directly, it will cause a waste of resources, lead to high production costs, and also affect work efficiency. Some composite rollers can replace the sleeves on the rollers, but the actual replacement requires the rollers to be disassembled and reinstalled. The replacement steps are relatively cumbersome and inconvenient for actual operation.

[0004] Therefore, we propose a centrifugal composite roller which is easy to replace the sleeve to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a centrifugal composite roller for easy replacement of sleeves, comprising a roller body 1, two groups of semi-arc shells 2 inserting a plug-in plate 3 fixedly connected on the surface into a plug-in slot 4 opened on the surface of the roller body 1, when the plug-in plate 3 is inserted to a predetermined position, the two groups of semi-arc shells 2 wrap the roller body 1 to form a sleeve on the surface of the roller body 1, and then the electromagnet 8 is started. When locked, the magnetism of the electromagnet 8 and the magnet block 9 are opposite, and the electromagnet 8 attracts the magnet block 9 to move, and the magnet block 9 moves at the same time. At the same time, the locking plate 5 is also driven to move, and the locking plate 5 is partially moved into the locking groove 7. The magnet block 9 and the electromagnet 8 are attracted to each other, thereby realizing the locking of the locking plate 5 and the plug-in board 3, and also completing the locking of the semi-arc shell 2. After the two groups of semi-arc shells 2 are locked, a sealing strip 10 is provided on the surface of one group of semi-arc shells 2, and a sealing slot 11 adapted to the sealing strip 10 is opened on the surface of the other group of semi-arc shells 2. The sealing strip 10 and the sealing slot 11 ensure the integrity of the two groups of semi-arc shells 2 when locked.

[0020] For details, please refer to Figure 1-3 When the semi-arc shell 2 needs to be replaced, restart the electromagnet 8 to make the magnetism of the electromagnet 8 the same as that of the magnet block 9. The electromagnet 8 and the magnet block 9 repel each other, and the magnet block 9 is affected by the magnetic force and slides into the sliding groove 6 provided on the surface of the locking plate 5. At this time, the locking plate 5 and the magnet block 9 are completely out of the locking groove 7. At this time, the plug-in plate 3 can be directly pulled out of the plug-in groove 4 to realize the disassembly of the semi-arc shell 2, and a new semi-arc shell 2 can be replaced for installation. The disassembly and installation are convenient and quick.

[0021] Working principle: two groups of semi-arc shells 2 insert the plug-in plates 3 fixedly connected on the surface into the plug-in grooves 4 opened on the surface of the roller body 1. When the plug-in plates 3 are inserted to the predetermined position, the two groups of semi-arc shells 2 wrap the roller body 1 to form a sleeve on the surface of the roller body 1. At this time, the electromagnet 8 is started. When locked, the magnetism of the electromagnet 8 is opposite to that of the magnet block 9. The electromagnet 8 attracts the magnet block 9 to move. The magnet block 9 also drives the locking plate 5 to move. The locking plate 5 partially moves into the locking groove 7. The magnet block 9 attracts the electromagnet 8, thereby realizing the locking of the locking plate 5 and the plug-in plates 3, and also completing the locking of the semi-arc shells 2. After the two groups of semi-arc shells 2 are locked, a sealing strip 10 is provided on the surface of one group of semi-arc shells 2, and a sealing slot 11 compatible with the sealing strip 10 is opened on the surface of the other group of semi-arc shells 2. The sealing strip 10 and the sealing slot 11 ensure that the two The tightness of the semi-arc shell 2 when locked is improved. When the semi-arc shell 2 needs to be replaced, the electromagnet 8 is restarted to make the magnetism of the electromagnet 8 the same as the magnet block 9. The electromagnet 8 and the magnet block 9 repel each other. The magnet block 9 is affected by the magnetic force and slides into the sliding groove 6 opened on the surface of the locking plate 5. At this time, the locking plate 5 and the magnet block 9 are completely out of the locking groove 7. At this time, the plug-in plate 3 can be directly pulled out from the plug-in groove 4 to realize the disassembly of the semi-arc shell 2. The new semi-arc shell 2 can be replaced for installation. The disassembly and installation are convenient and fast, which solves the problem that if the roller is replaced directly, it will cause a waste of resources, resulting in high production costs and affecting work efficiency. Some composite rollers can replace the sleeves on the rollers, but the rollers need to be disassembled and reinstalled during actual replacement. The replacement steps are relatively cumbersome and inconvenient for actual operation.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
