Abstract
The invention provides a large leveller which is an eight-roller horizontal type leveller. The large leveller comprises an inlet horizontal roller, an inlet vertical roller which is connected with the inlet horizontal roller, eight levelling rollers which are connected with the inlet vertical roller, an outlet vertical roller which is connected with the levelling rollers and an outlet horizontal roller which is connected with the outlet vertical roller, the inlet vertical roller, the levelling rollers and the outlet vertical roller are arranged on a levelling shaft, and the eight levelling rollers comprise the upper levelling rollers and the lower levelling rollers. According to the large leveller, positive and negative bending can be conducted on boards for multiple times, and in the levelling process, defects such as bends, twists, scratches and levelling marks do not occur.
Description
Technical field
The present invention relates to a kind of large-scale level(l)ing machine, belong to field of mechanical technique.
Background technology
Level(l)ing machine calls off again flat machine, purl machine, levelling machine, arbor press, straightener.Major function is to metal blank goods, bending of band coiled strip. torsional deformation carries out accurate leveling, rectification.Level(l)ing machine is equipment conventional in sheet fabrication, and the sizing of level(l)ing machine depends primarily on by the thickness of school band, material and requirement.Expect that thicker desired structure rigidity is better, roller number is fewer, and roller is through larger, and power larger (fabric width is certain), vice versa.Generally there are double 7,9,11,13 rollers and generally have quadruple 11,13,15,17,19 roller, sixfold 17,19 roller.
Level(l)ing machine is suitable for sheet material scope: the sheet metals such as hot and cold sheet material, galvanized sheet, aluminium sheet, Coil Coating Products, stainless steel materials.Because it is convenient and simple for operation, range of application spreads all over multiple industries such as machinery, metallurgy, building materials, chemical industry, electronics, electric power, light industry, special in industries such as shipbuilding, rolling stock, boiler bridge, metal structure factories, become indispensable necessary product in production.
Existing level(l)ing machine also often there will be in straightening process bending, reverse, chew, rectify the defects such as trace.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of large-scale level(l)ing machine is provided.
Large-scale level(l)ing machine of the present invention, described level(l)ing machine is eight roller horizontals, comprise: inlet water plain-barreled roll, the entrance edger roll be connected with inlet water plain-barreled roll, the smoothing roll be connected with entrance edger roll, the outlet edger roll be connected with smoothing roll and the outlet horizontal roller be connected with outlet edger roll, described entrance edger roll, smoothing roll and outlet edger roll are located on straightening shaft, described smoothing roll has 8, comprises row's smoothing roll and lower row's smoothing roll.
Preferably,
Described upper row's smoothing roll and lower row's smoothing roll respectively have 4.
Large-scale level(l)ing machine of the present invention can carry out repeatedly positive contraflexure to sheet material, there will not be in straightening process bending, reverse, chew, rectify the defects such as trace.
