Description

Correction system of plate material {correction system of metal}

The present invention relates to a bending correcting device for a plate material, and more particularly to a bending correcting device for removing stress from a plate material which is sequentially extruded and correcting the bending shape of the plate material after removing the stress, And a system using the same.

Generally, there are defective shape and defective deflection of the plate material to be extruded. The defective deflection can be corrected by a roller leveler using a conventional cylindrical roller. The defective shape is caused by the difference in elongation in the longitudinal direction of the plate material and can not be corrected unless plastic elongation and contraction in the longitudinal direction of the plate material are imparted. It is called camber that the shape defects are greatly bent along the length direction.

Conventionally used roller levelers apply a bending force repeatedly to a plate or a coil plate (sheet material) by using cylindrical rollers arranged in zigzag rows divided into two groups of upper and lower sides to remove distortion. This roller leveler can correct defective deflection of the plate material.

As a method of correcting the camber of the plate material, various methods have been proposed. However, there is a problem in that calibration can not be properly performed unless the setting of the roller leveler is changed depending on the left and right sides of the camber.

In order to calibrate the plate material as described above, it is required to perform calibration in a plurality of apparatuses, so that there is a problem that the cost and the location of each apparatus are narrow.

According to the present invention, there is provided a sheet material deflection correcting system comprising: sequentially supplying a plate material;

Removing the stress through the first leveler;

And a step of authorizing the calibrated material in the winding section through the first to third steps.

That is, a step of supplying the plate material to remove the stress, correcting the deformation in the width direction of the plate material from which the stress has been removed, and then immediately correcting the deflection in the longitudinal direction.

At this time, the second step and the third step can be changed in order.

For example, it is possible to use a deformation according to the characteristics of a material in the order of correcting the warp in the longitudinal direction and correcting the deformation in the width direction.

The calibration system of the present invention will be described in more detail with reference to the drawings shown in FIGS. 1 to 3.

First, as shown in FIG. 1, a feeder 10 for feeding a workpiece 1 to be processed is provided. The workpiece 1 fed from a feeder is moved in the widthwise direction and the longitudinal direction And is provided with a calibrating device (100) for flat calibrating, and a catching part (20) for recovering the plate material (1) calibrated in the calibrating device.

That is, the first leveler 110 removes the stress of the plate material. A second step of correcting the deformation in the width direction in the second leveler 130; And a third step of flatly correcting the strain in the longitudinal direction through the third leveler 140.

The structure of the first to third levelers includes a pair of adjustment member main bodies 111 for supporting the lower rollers, a plurality of lower rollers 115 provided between the adjustment members, And an adjusting member 120 assembled to the upper end of the upper roller 125 and having a plurality of upper rollers 125 therebetween.

The adjusting member main body 111 is formed with a receiving portion 112 so that the adjusting member 120 is assembled inside the upper portion and a guide projection 113 is formed on the inner wall of the receiving portion.

Between the main body and the adjustment member, the lower rollers are equally spaced by the shaft 114.

Each of the shafts 114 is provided with an interlock gear 114 and a driving gear k provided at an end thereof with a sprocket 117 and interlocked with the sprocket.

The upper adjusting member 120 is assembled to the receiving portion of the adjusting member main body and interlocked with each other.

The adjustment member 120 is provided with an adjustment surface 122 with both side ends inclined upward and downward and a guide groove 123 is formed between the adjustment surfaces so that the guide protrusion 113 of the adjustment member main body is fitted. These bodies are formed as a pair, and the upper roller 125 is disposed by the shaft 124 between the pair of bodies.

At both ends of the shaft 124, a driving gear 126 is provided so as to be engaged with and rotated with an interlocking gear 116 provided in the adjusting member main body.

The operation of the bending correction system of the present invention constructed as described above will be described.

First, the first leveler adjusts the adjustment means T in the left and right direction to lower the upper roller to the lower roller so as to narrow the width to maintain a certain degree of bending.

The second leveler adjusts only the rear adjusting means or the front adjusting means according to the deformation of the plate material so that the upper roller is formed to have a constant inclination angle.

The second leveler is constituted by two stages and the first stage is inclined rearwardly and the second roller is inclined forwardly so as to calibrate an unbalanced rear face in the first stage and correct the unbalanced front face in the second stage .

The third leveler is provided with the upper roller horizontally aligned with the lower roller as it goes backward by adjusting the adjusting means T for the portion into which the material is put.

When the upper roller of the first leveler to the third leveler is adjusted in this way, the material is firstly subjected to the stress, the unbalanced warping of the front and rear widths can be corrected, And the plate material having a certain width and level is completed.
