Description
Technical field
The present invention relates to straightening equipment, especially a kind of stretch bending-straightening machine rectifys roller assembly.
Background technique
The plate shape problem of strip includes two aspects such as the lateral thickness difference of strip and the straightness of strip, asking in terms of this
Topic for essence, be as participate in the presence of stress inside strip and caused by.Therefore it needs to align strip, so that
The plate pictograph for obtaining strip closes requirement.
Straightener is the equipment aligned to metal material, and straightener squeezes metal material etc. by straightening roll
It is set to change straightness.Straightener is divided into roll leveller and tension flattening machine.But the plate shape for thickness less than 2mm lacks
It falls into, roll leveller is difficult the strip for making strip leveling, especially thickness be less than 0.5mm, it is virtually impossible on roll leveller
Leveling.And tension flattening machine also can not leveling to wooden dipper song.
Continous way stretching-bending straightener (Continuous Stretch Bending Leveller), abbreviation stretch bending are rectified
Straight machine is to make band in stretching, bending, straightening process using minor diameter bending roll, while generating stretching and bending deformation
Thin strip straightener.
Stretch bending-straightening machine is to extend theory according to the elastoplasticity of material to carry out leveling to band.Its basic principle is that need to rectify
Flat band continues through the bending roll for the multiple groups minor diameter arranged alternatively up and down under the tension force effect that tension roll assembly applies,
It stretches and produces longitudinal extension of plasticity under curved synergy along its length, make the length of each longitudinal fiber of band
It is intended to unanimously, to reduce the inhomogeneities of longitudinal internal stress distribution inside band, improves the straightness of band.Stretch-bending straightening
Machine is made of roll leveller and tension flattening machine two parts, therefore combines roll leveller and tension flattening machine well
Advantage is able to achieve compared with large plastometric set in the case where tensile stress level is far below Materials Yield Limit, is improving the flat of thin plate
It while directly spending, also helps the anisotropy for improving material and avoids yield point elongation and prevent the formation of skid wire, be relatively wide
The coiled continuous straightening of the strip of range provides possibility.
Summary of the invention
The present invention provides a kind of strong roller assembly of stretch bending-straightening machine, and using three-decker, support roller supports intermediate calender rolls, intermediate calender rolls
