Description

Flattening roller of decoiler capable of self-adapting to balance stress

Technical Field

The invention relates to the technical field of sheet metal processing, in particular to a flattening roller of a decoiler, which can self-adaptively balance stress.

Background

The flattening machine is a special device integrating flattening, shearing and splitting of metal plates, and is used for achieving flattening by repeatedly extruding and deforming band steel between an upper flattening roller and a lower flattening roller, eliminating stress, and then shearing the plates to obtain flattened steel bars. When the flattening part of the decoiler works, the rotating shaft of the flattening roller is eccentric after deformation due to extrusion or mechanical vibration, the internal stress of steel cannot be effectively removed and balanced during rotation, even the stress concentration of strip steel is intensified, and the effect of flattening cannot be achieved. 200580007182.4 discloses that the magnetorheological fluid compensates the deformation of the shell when the roller is deformed to make the shell stress uniform and smooth, and aims to obtain a smooth surface with a high tolerance.

With the use of the leveling roller, the more the local deformation number is, the more the buffer units 3 press the shaft bracket 4 to increase the inner ring friction force and increase the gap between the outer ring lining block 31 and the shell 1, so that the shell 1 and the inner main body generate relative slip, and simultaneously, the magnetic field generating device in the container 32 controls the magnetorheological fluid 34 to reduce the viscosity thereof, so that the position of the shell 1 is automatically adjusted, most local deformation falls into the gap between the lining blocks 31 of the adjacent buffer units 3 and enters a relative balance position, and the eccentricity of the rotating shaft 5 is eliminated.
