Metal plate coils generally will through aligning unit aligning, shearing, just can become operable rectangle plate.But the curvature of the spinal column defective that occurs in various degree at process light plate (especially, slab) is very general.The distortion of the circular arc of this steel plate width direction generally in the 5-25mm/m scope, although the scope that allows in GB is subject to severely restricts in actual use, causes the waste of resource.In the present solution, be a pair of concavo-convex roller of arrangement or mobile single roller before straightener basically, its principle all is with by force recurvation of steel plate, in the hope of eliminating or reduce the curvature of the spinal column defective of steel plate before entering straightener.But effect is unsatisfactory in actual applications, and these technical schemes do not obtain further propagation and employment.
According to reported in literature and our observation, steel plate curvature of the spinal column defective is except the coilcooling inequality causes the factor of stress difference, and the mechanical change of steel plate also is the important reason of its formation during shearing
(1)The built-in presser feet of shearing machine and external presser feet, the steel plate curvature of the spinal column defective after the shearing then present distinct " the head curvature of the spinal column " and " the afterbody curvature of the spinal column " two kinds of forms.This shows, settle the technical scheme of concavo-convex roller or mobile single roller unreasonable before the existing straightener.Be mainly manifested in concavo-convex roller or the single roller press-bending quantity not sufficient on the steel plate width direction, such as the concavo-convex roller that domestic certain producer uses at the aligning unit, the press-bending amount only has 30mm/1800mm.Under this press-bending amount, what steel plate occured only is strain, but not reaches the plastic deformation of straightening function
(2)In mobile single roller scheme, except the press-bending quantity not sufficient, because the contact point of recurvation steel plate only has 3, remain in fact the pattern of a simple pressure straightener.And the shortcoming of this kind mode is to make each section of steel plate of even bending obtain continuously aligning, therefore can not guarantee straightening quality, can only be used for local aligning and auxiliary aligning
(3)In the existing scheme, if further strengthen the press-bending amount of steel plate, will cause the counter curvature of steel plate width direction excessive, steel plate can't enter upper and lower roll straightener roller parallel to each other, and the aligning on the length direction also just can't be finished.The more important thing is, previously all having ignored the mechanical change that steel plate occurs when shearing in the scheme also is to cause the important origin cause of formation of curvature of the spinal column defective, directly output after shearing, and the blanking code piles and is processed finished products, the curvature of the spinal column defective that shearing causes can't be corrected, and the flatness of straightening steel plate is difficult to guarantee.
