2. Description of the Related Art Generally, there is a shape error of several tens to several hundreds of μm in the width direction of the long section steel, and several meters in the length direction.
There is a shape error of m to several tens of mm. Conventionally, when polishing this long shaped steel, the side surface is shaped by a grinding process such as belt grinding and buffing, and the upper surface is shaped according to the shape of the material.

Further, cold rolled steel such as angles and square tubes having relatively good surface roughness of the material and good shape accuracy are mass-produced by a mass-production polishing machine mainly for buffing. Since polishing is the main, advanced polishing has not been carried out.
In addition, hot-rolled steel with poor surface roughness and shape accuracy
Although small-scale production is carried out with a hand tool, only small-scale polishing is carried out due to shape errors in the width and length directions.

[0004]

Conventionally, when polishing the long section steel, since the long section steel has a shape error in the width direction and the length direction, the long section steel is fixed to a surface plate or the like. In addition, since the polishing portion is not sufficiently restrained, vibration occurs in the polishing portion, and a side surface and an upper surface are not polished. In addition, there is a problem that deformation is added due to heat generated during polishing, and the effect is particularly great in stainless steel, which makes polishing difficult. The present invention has been made in view of the above points, and an object of the present invention is to provide a long steel polishing apparatus for polishing long steel into a stable, high-quality mirror surface.

[0005]

In order to solve the above-mentioned problems, a long steel polishing apparatus of the present invention is provided with a support base on which long steel is placed and conveyed, and a support base. A polishing tool that polishes shaped steel, a pressing tool that is placed before and after the polishing tool in the direction of transportation of the shaped steel and that pushes the shaped steel downward with a roller, and both sides of the shaped steel that are installed near the pressing tool. And a fastener that is pressed by a roller.

[0006]

The long-shaped steel polishing apparatus of the present invention configured as described above mounts and transports long-shaped steel on a support table, and rolls the rollers before and after the polishing tool in the conveying direction of the shaped steel. A pressing tool for pressing the shaped steel downward is arranged, and a clamping tool for pressing the side surface of the shaped steel with a roller is arranged in the vicinity of the pressing tool, and the shaped steel is polished by a polishing tool. ， Long shaped steel is fixed to the support base by the fastening tool, the polishing part is sufficiently restrained, the shaped steel is polished to a stable and high quality mirror surface, and the industrial utility value becomes enormous.
