JPS6120612A - Width direction tension distribution adjusting device of rolling material - Google Patents

Abstract

PURPOSE:To adjust a width direction tension distribution with a high accuracy, and to improve a quality of a formed part by fitting a shaft part of a freely inclinable roller into a bearing for supporting a freely liftable roller, and supporting it. CONSTITUTION:At the time of rolling, a roller 3 and 12 are lifted or lowered by a prescribed quantity by lifting or lowering brackets 7, 14 by a prescribed quantity by a fluid pressure cylinder, etc., and the roller 3 is inclined at a prescribed angle. A rolling material S contacts to the rollers 3, 12, therefore, the rollers 3, 12 are rotated by a frictional force, and a supporting roller 17 is rotated by a rotation of the roller 12. Also, the roller 3 is inclined by a prescribed angle in the prescribed direction, and also a height of the roller 12 existing between the rollers 3 can also be set to a prescribed height, therefore, a tension distribution in the width direction of the rolling material S can be adjusted optionally. Also, since the roller 12 exists between the rollers 3, it does not occur that the rolling material S is flawed by the inside end part of the roller 12.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus that can accurately adjust the widthwise tension distribution of a rolled material without causing defects in the rolled material.

[Conventional technology]

It has been conventionally practiced to control the cross-sectional shape of a plate rolled by a rolling mill by adjusting the tension distribution in the width direction of the rolled material.

An example of the device for adjusting the widthwise tension distribution of the rolled material used when performing this control is shown in FIG. The width direction tension distribution of the horizontally rolled material (8) is adjusted.

[Problem that the invention seeks to solve]

However, in the width direction tension distribution adjusting device described above, when the roller (α) is tilted as shown in FIG. In addition, it is difficult to apply a predetermined tension to the rolled material (8) in the gap between the rollers (α), so the tension distribution in the width direction of the rolled material (s) is arbitrarily adjusted with high precision. There was a first-class problem that was difficult to solve.

The present invention has been made to solve the above-mentioned problems by making it possible to accurately adjust the tension distribution without causing flaws in the rolled material.

[Means for solving problems]

The present invention includes a rotatable roller that is divided into a plurality of parts in the axial direction and can be tilted in the vertical direction, and a roller that can be raised and lowered between the rollers, and a shaft that supports the roller that can be raised and lowered. The shaft portion of the tiltable roller is fitted into and supported by the second receiver.

[For production]

Therefore, in the present invention, the tension acting in the width direction of the rolled material is adjusted to a predetermined state by adjusting the height direction position of the roller that can be raised and lowered and also adjusting the inclination of the roller that can be tilted.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Figures 1 and 2 show an embodiment of the present invention, in which (1) is a rolling mill, (2) is a rolling mill, and the width direction This is a tension distribution adjustment device. To explain the width direction tension distribution adjusting device (2), a bearing (4
), and spherical bearings (6) are fixed to both ends of the roller shaft (5) fitted to the bearing (4), and the spherical bearing (
Among 6), a spherical bearing (6) fixed to the outer end of the roller shaft (5) is supported by a spherical seat (8) fitted to a bracket (7), and the bracket (7) is connected to a fluid (not shown). It should be possible to move up and down using a pressure cylinder.

Fit the spherical seat αQ into the hollow part of the cylindrical body (9).

A spherical bearing (6) fixed to the inner end of the roller shaft (5) is fitted to the spherical seat 00, and a roller (3) is fitted to the bearing (b) fitted to the outer periphery of the cylindrical body (9). (3) A bracket Q with a roller (2) fitted therebetween, which can be raised and lowered by a fluid pressure cylinder Q [phase]
Attach the two shafts Q to 41 parallel to the roller (A).

The support rollers (lη) are fitted into the shaft 0 frame through bearings (c), and the collars (lη) provided at both ends of the support rollers 20 are fitted.
7α) to support the grooves (12a) at both ends of the roller (6).

During rolling, the bracket (
7) By raising and lowering the α shaft by a predetermined amount, the roller (3) and @ are raised and lowered by a predetermined amount, and the roller (3) is tilted at a predetermined angle. Since the rolled material (8) is in contact with the rollers (3) and (2), the rollers (3) and (6) are moved by the frictional force with the rolled material (8).
is rotated, and the rotation of the roller (2) causes the support roller aη to rotate. In addition, the rollers (3) are tilted at a predetermined angle in a predetermined direction, and the height of the roller (6) between the rollers (3) can also be set to a predetermined height, so that the rolled material (s)
The tension distribution in the width direction can be adjusted arbitrarily, and since the roller (2) is located between the rollers (3), the rolled material (8) will not be scratched by the inner edge of the roller (A)◇
Furthermore, since the roller shaft (5) is provided with a spherical bearing (6), the roller (3) can be tilted smoothly.

1. In the embodiment of the present invention, the case where two rollers whose inclinations can be adjusted is provided has been described, but it is also possible to implement any number of rollers as long as they are provided. Good shape, etc.
It goes without saying that various changes may be made without departing from the spirit of the invention.

〔Effect of the invention〕

According to the device for adjusting the tension in the width direction of a rolled material of the present invention, the rolled material is not easily scratched, and the widthwise tension distribution thereof can be adjusted with high accuracy, so that the product quality of the rolled material is improved, etc.
Various excellent effects can be achieved.
