Abstract

The invention discloses a small-roller-diameter (phi is less than or equal to 70 millimeters) multi-roller straightening machine, which is applied to a discontinuous or continuous unit of a sheet or straightening band steel on a push-pull acid washing unit and iron scale damaging equipment. The straightening machine comprises a multi-output-shaft gear reduction distribution box, a bending section bending roller set, a flattening section straightening roller set, a hydraulic cylinder and the like, wherein the bending roller set and the straightening roller set consist of a support roller, a middle roller and a straightening roller respectively; the support rollers and the straightening rollers are driven rollers; the middle rollers are driving rollers; and the straightening rollers have small-roller-diameter structures with the roller body diameters of not greater than 70 millimeters. Due to the adoption of the straightening machine, the problem that a small-diameter straightening roller cannot bear torque transmission easily is solved; and the conventional middle roller is improved from a driven roller driven by band steel to a driving roller connected with a shaft coupling, so that the difficulty in directly driving the straightening roller is avoided and the effects of better realizing scale breaking and plate straightening capacity by using a small-roller-diameter straightening roller are achieved.

Description

Pony roll footpath multi-roll straightening machine

Technical field

The present invention relates to a kind of pony roll footpath multi-roll straightening machine, be specially on the discontinuous or continuous unit or pull pickler group that is applied in thin plate, be used for aligning band steel, broken iron scale equipment, belong to the iron and steel metallurgical industry aligning and break the phosphorus technical field, the pony roll described in this specification is meant that directly its roll body diameter dimension is not more than the 70mm roller.

Background technology

In the existing known technology, the pull pickler group is the unit of the monovolume pickling of discontinuous work, and its entrance is provided with straightener, is used for aligning band steel, because monovolume duty and discontinuous unit, unit tension force is less, so straightener is initiatively to align, smoothing roll should be aligned band steel driving torque again, its roller footpath is big (more than the Ф 130mm) generally, be difficult to performance aligning band steel functional, therefore be mainly used in the part end to end of aligning band steel, the effect that does not also reach brokenly phosphorus.Correct theoretical according to sheet bending, improve the drafts that the precision of correcting sheet material depends primarily on the roller number of arbor press and makes the working roll of sheet bending distortion, and working roll roller footpath and roll spacing, and in the continuous acid-washing aligning, because of unit tension force bigger, smoothing roll less (Ф 70mm following) can't bear or install the shaft coupling of transmitting torque.(application number: 200510048186.9 applyings date: 2005-12-12) disclosed characteristics are that working roll and backing roll device have into to China's utility model patent " multi-roller steel plate-flattening machine ", exit portion and mid portion, each part each has independently transmission device, the independent transmission of the working roll of various piece, the roller of importing and exporting the part employing directly is Ф 200mm, the intermediate calender rolls diameter is Ф 320mm, between the working roll of turnover part and mid portion, can adjust the intermediate calender rolls of depressing and opening separately in addition, its diameter is Ф 260mm, and this utility model and be not suitable for thin plate continuous acid-washing and the aligning; (application number: 200820010136.0 applyings date: 2008-01-09) disclosed is nine roller straighteners in a kind of differential roller footpath to China's utility model patent " nine roller straighteners in differential roller footpath ", comprise smoothing roll group down, driving mechanism, the upper straightening roll group, depress adjusting device etc., following smoothing roll group is the smoothing roll that last roll surface is in five differential roller footpaths on the same horizontal plane, the upper straightening roll group has the smoothing roll in four differential roller footpaths, per two upper straightening rolls are a group, 4 rollers of its entrance side directly are Ф 130mm, 5 rollers of outlet side directly are Ф 190mm, roller footpath, two places is all greater than Ф 70mm, be difficult to performance aligning band steel functional, the effect of broken phosphorus is poor.

In the pull pickler group, a kind of straightener has the aligning and the double effects of broken phosphorus, and its working roll adopts pony roll footpath (aligning of Ф≤70mm), the novel product that reaches economic, practical purpose necessitates simultaneously.

Summary of the invention

The problem that the object of the invention proposes at background technology, a kind of pony roll footpath (multi-roll straightening machine of Ф≤70mm) is disclosed, be applied in the discontinuous or continuous unit of thin plate or the aligning band steel on the pull pickler group, broken iron scale equipment, be applicable under the small tension receiving coil condition aligning and the broken phosphorus of band steel, reach and improve the good double requirements of fruit of plate shape and pickling.

Technical scheme of the present invention is: pony roll footpath multi-roll straightening machine, comprise main motor, have more shaft gear deceleration distributor box, Hooks coupling universal coupling, bending section bending roll group, leveling section smoothing roll group, hydraulic cylinder, memorial archway form, described bending section bending roll group and leveling section smoothing roll group are formed by backing roll, intermediate calender rolls and smoothing roll, described backing roll and smoothing roll are driven roll, intermediate calender rolls is a drive roll, it is characterized in that: the smoothing roll of the smoothing roll in the bending section bending roll group, leveling section smoothing roll group all is the pony roll gauge structure that the roll body diameter is not more than 70mm.

The invention has the beneficial effects as follows: (smoothing roll (working roll) of Ф≤70mm) is difficult to bear the moment of torsion problem of transmission to have solved minor diameter, traditional intermediate calender rolls is improved to the drive roll that is connected with shaft coupling by the driven roll that the band steel drags, avoided the difficult point of direct transmission smoothing roll, reached pony roll footpath smoothing roll and can better realize brokenly phosphorus and straightening plate shape ability effect.
