Abstract
The present invention relates to a leveler capable of processing a multi-spec material capable of precisely leveling work without pressurizing the equipment by uniformly pressurizing all areas of the material with various thicknesses and widths. The leveler capable of material processing includes: an upper leveling roller portion in which a plurality of upper leveling rollers are installed parallel to each other at regular intervals; An upper load distribution roller unit installed on the upper leveling roller so as to be in common contact with the adjacent upper leveling rollers and distributing a load applied to the upper leveling roller; An upper pressure roller portion provided above the upper load distribution roller so as to be in common contact with the neighboring upper load distribution rollers and pressing the central portion of the upper load distribution roller portion downward; A plurality of lower leveling rollers spaced apart from each other such that the lower leveling rollers face the upper leveling rollers; A lower load distribution roller unit installed below the upper leveling roller to commonly contact adjacent lower leveling rollers and distributing a load applied to the lower leveling roller; And a lower pressing roller portion provided below the lower load distribution roller so as to be in common contact with the neighboring lower load distribution rollers and pressing the central portion of the lower load distribution roller portion upward.
Description
The present invention relates to a leveler, and more particularly, to a leveler capable of processing a multi-spec material capable of precisely leveling a workpiece by uniformly pressing all areas of a workpiece with various thicknesses and widths, .
The leveling operation refers to a flattening operation of a flat sheet material rolled in the form of a roll, and in this leveling operation, a leveler is used which is pressed and stretched in a state where the curled material is inserted between the rollers.

However, in the conventional leveler, it is impossible to cope with materials having various thicknesses and widths in the course of use. Particularly in the case of processing a material having a small width, the central portion of the upper and lower
SUMMARY OF THE INVENTION It is an object of the present invention to provide a leveler capable of processing a multispecific material capable of accurately leveling workpieces without imposing a strain on the equipment by uniformly pressing all areas of the workpieces with various thicknesses and widths .
According to an aspect of the present invention, there is provided a leveler capable of processing a multispecific material, comprising: an upper leveling roller unit having a plurality of upper leveling rollers spaced apart from each other at regular intervals; An upper load distribution roller unit installed on the upper leveling roller so as to be in common contact with the adjacent upper leveling rollers and distributing a load applied to the upper leveling roller; An upper pressure roller portion provided above the upper load distribution roller so as to be in common contact with the neighboring upper load distribution rollers and pressing the central portion of the upper load distribution roller portion downward; A plurality of lower leveling rollers spaced apart from each other such that the lower leveling rollers face the upper leveling rollers; A lower load distribution roller unit installed below the upper leveling roller to commonly contact adjacent lower leveling rollers and distributing a load applied to the lower leveling roller; And a lower pressing roller portion provided below the lower load distribution roller so as to be in common contact with the neighboring lower load distribution rollers and pressing the central portion of the lower load distribution roller portion upward.
In the present invention, it is preferable that the upper load distribution roller is formed to have the same length as the upper leveling roller.
In the present invention, it is preferable that the lower load distribution roller is formed to have the same length as the lower leveling roller.
Further, in the present invention, it is preferable that the upper pressure roller presses the central portion of the upper load distribution roller.
In the present invention, it is preferable that the lower pressure roller presses the central portion of the lower load distribution roller.
In the present invention, the upper pressure roller portion may include: an upper central pressure roller for pressing a center portion of the upper load distribution roller; An auxiliary pressure roller provided on one side of the upper central pressure roller; And a pressure driver for pressing the central pressure roller downward.
In the present invention, the lower pressing roller portion may include: a lower central pressing roller for pressing a center portion of the lower load distribution roller; A lower auxiliary pressure roller provided on one side of the lower central pressure roller; And a lower pressing driver for pressing the lower central pressing roller upward.
It is preferable that the leveler of the present invention further comprises a pressure moving means for moving the upper pressing roller portion downward or the upper pressing roller portion upward.
The leveler according to the present invention is advantageous in that the leveling roller is not deformed even if the material of various widths is processed by the load distribution roller unit and the material of various thicknesses can be processed by adjusting the gap between the upper and lower leveling rollers .
