Embodiment Construction

[0020] Embodiments of the present invention will be described below with reference to the drawings.

[0021] figure 1 It is a side view showing the roller leveler according to one embodiment of the present invention, figure 2 is its main view. The roller straightener 100 of the present embodiment includes: a housing 1 ; an upper frame 2 provided inside the housing 1 ; and a lower frame 3 provided to support the housing 1 . A pressing cylinder 4 (also referred to as a pressing cylinder 4) is arranged between the housing 1 and the upper frame 2. Below the upper frame 2, the upper roller frame 5 is clamped by the upper roller to the cylinder (not shown). hoist. On the other hand, a lower roll frame 10 is provided on the lower frame 3 .

[0022] In addition, in this specification, the term "press down" is not only figure 1 The case where the pressure is applied downward as shown also includes the case where the pressure is applied upward as will be described later as a modif...

Abstract

The roller straightening machine (100) is equipped with: a straightening roller unit (20), which has a plurality of staggered configurations arranged on the upper and lower sides of the metal plate (P) to be straightened, and clamps the metal plate with one side ( P) Straightening rollers (6, 8) that rotate while making the metal plate pass through the straightening; hydraulic pressing cylinder (4), which presses the metal plate through the straightening rollers (6, 8); driving device ( 15, 16), which rotate the straightening rollers (6, 8) to pass the metal sheet, the straightening roller unit (20) has: fluid flow forming mechanisms (21, 22), which are arranged along the metal sheet (P) Between the straightening rollers (6 or 8) adjacent to the passing direction of the metal sheet, the scale peeled off from the surface of the metal sheet is formed between the straightening rollers (6 or 8) and blown away to the end side in the width direction of the metal sheet. the fluid flow; the rectification member (19), which guides the fluid flow to the outside.

Description

technical field [0001] The present invention relates to a roller leveler for straightening a metal plate and a leveler roller unit used in the roller leveler. Background technique [0002] Although rolling, cooling, and the like are performed in the process of manufacturing a metal plate such as a steel plate, the metal plate undergoes bending or wave-like deformation during these steps. Therefore, for the purpose of correcting such bending or wavy deformation and flattening the metal plate, a roll leveler in which a plurality of straightening rolls are arranged in a vertical zigzag shape is used. [0003] Roller straightening machines pass the metal plate to be straightened with the upper roll pressed into the lower roll or the lower roll pressed in with the upper roll, and the metal plate is straightened by applying repeated bending to the metal plate. Curved or wavy flattening of the board. [0004] When scale (scale: scale-like flakes) is formed on the surface of the m...
