Problems solved by technology

[0006] However, there is a chock on the roll end side that receives the roll, and since the flow of fluid such as air that blows off the scale collides with the chock, a part of the scale that was blown off temporarily hits the metal plate. side reflux

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 front 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 modi...

Abstract

The present invention provides a roller leveler (100) which comprises a leveling roll unit (20), an oil-pressure pressing cylinder block (4), and drive devices (15, 16), wherein the leveling roll unit (20) has multiple leveling rolls (6, 8) which are interleavingly arranged on a metal plate (P) to be corrected, and clamp the metal plate (P) for correction, and rotate by the mode of making the metal plate get through at the same time,the oil-pressure pressing cylinder block (4) presses the metal plate through the leveling rolls (6, 8),the drive devices (15, 16) drive the leveling rolls (6, 8) to rotate and make the metal plate get through,the leveling roll unit (20) comprises fluid flow forming mechanisms (21, 22) which are arranged between the leveling rolls (6 or 8) along the through plate direction of the metal plate (P),the fluid flow is formed from the scale cinder peeled off from the surface of the metal plate to the end side of the width direction of the metal plate,and the rectification component (19) guides the fluid flow outwards.

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...
