本考案は、幅方向に厚さ不同部を有する金属板

削ベルトに関するものである。[Detailed Description of the Invention] The present invention relates to a grinding belt for the surface of a metal plate suitable for use in finish grinding of a metal plate having uneven thickness portions in the width direction.
一般に、熱間圧延及び冷間圧延を経て製造され

するのが普通である。 In general, strip coils such as cold-rolled steel sheets that are manufactured through hot rolling and cold rolling often develop various surface defects during the manufacturing process. Usually, the product is shipped after being subjected to a mechanical process using a belt or a grindstone to remove these defects.

きることなど、多くの利点があるためである。 As for the mechanical method using a belt or a grindstone, in the case of a strip coil, a strip grinder is mainly used, and an example thereof is shown in FIG.
In the figure, 1 is a strip running at a relatively low speed in the direction of the arrow, 2 is a drive roll, and 3 is a contact roll made of an elastic material such as rubber. An endless grinding belt 4 to which abrasive material is fixed is hung and rotates at high speed in the direction of the arrow. In addition,
The reason why a grinding belt is used for grinding the strip surface is that it has many advantages, such as the fact that there is no limit to the width of the belt, wide belts are easily available, and the roughness of the finished surface can be selected arbitrarily.
このようなストリツプ表面の仕上作業において

転移動し、ストリツプ１の表面を研削する。 In this kind of finishing work on the surface of the strip, the contact roll 3 is pressed with a uniform force over the entire width of the strip 1 running in the direction of the arrow, and drives the drive roll 2 to remove the grinding applied thereto. Contact roll 3 via belt 4
When rotated, the grinding belt 4 rotates in the direction of the arrow between the strip 1 and the contact roll 3, and grinds the surface of the strip 1.

ルに巻取るのが困難な場合が屡々発生する。 By the way, the strip 1 whose surface is ground with a grinding machine as described above, especially the strip made of stainless steel plate, has poor workability, and due to the roll bending of the rolling mill, the thickness in the width direction is not always uniform as shown in Figure 2. Generally, the thickness of both ends is also
The center thickness t 1 is often thicker than t 2 (this t 1 > t 2 is generally called the sheet crown,
(expressed as t 1 - t 2 /t 1 ×100). Such stainless steel sheet strips are usually rolled into thinner strips by the user after being shipped from the factory. For example, a strip with a width of 94 cm and a thickness of 2 mm is divided into three parts in the width direction (A, B in Figure 2,
A), each with a width of 30 mm and a thickness by cold rolling.
Refinish and process into strips of approximately 0.15 to 0.2 mm. However, since each divided piece, especially the pieces on both sides (part A), have different thicknesses in the width direction,
Not only is it difficult to uniformly finish the strip to the desired thickness across the entire width, but the uneven thickness also causes the rolled strip to meander, resulting in poor surface quality such as optics, surface flaws, and shape. Not only that, but it is often difficult to wind it into a coil.

が強く要求されている。 However, as shown in FIG. 3, the grinding belt 4 is pressed against the surface of the strip 1 by a contact roll 3 made of an elastic material that conforms to the surface of the strip 1 in the width direction. Grinding is done with a nearly uniform cutting allowance over the entire surface. Therefore, although conventional grinding machines can remove defects on the surface of the strip, they cannot make the thickness uniform in the width direction and eliminate the sheet crown. Another method is to eliminate the sheet crown by roll bending adjustment, crown control rolling, etc., but it is difficult to eliminate the sheet crown stably, uniformly, and accurately, and the equipment is expensive. Become something. For this reason, when grinding the strip surface, it is possible to not only remove surface defects, but also
There is a strong need for an inexpensive method of eliminating seat crowns.

である。以下図面により本考案を説明する。 The present invention was developed to solve the above-mentioned problems, and is characterized by a multi-layered central part for fixing the abrasive material to the base material of the abrasive belt. The object of the present invention is to obtain a grinding belt for the surface of a metal plate, which can eliminate the defects of the metal plate and also eliminate the sheet crown so that the thickness in the width direction can be finished almost uniformly. The present invention will be explained below with reference to the drawings.

In the figure, reference numeral 5 denotes a base material such as base paper or treated cloth constituting the belt body, and an abrasive material 6 is fixed to the surface with an adhesive. As is well known, in conventional abrasive belts, abrasive material is fixed to the base material with a substantially uniform thickness over the entire surface of the base material, but in this embodiment, abrasive material 6 with substantially equal grinding ability and particle size is used.
, both sides of the base material 5 in the width direction (for example, range a)
is fixed in a single layer, and the central part is fixed in multiple layers.

Since the entire surface in the width direction is ground as shown by the broken line (b), not only can surface defects of the strip 1 be completely removed, but also a strip having a uniform thickness can be obtained over the entire width direction.

ころ、きわめて好結果が得られた。 As an embodiment of the present invention, a single layer of abrasive material 6 is fixed to a range of 20 cm to 40 cm from both ends of a base material 5 having a width of 130 cm (indicated by a in FIG. 4), and then the same particle size is applied to the center. When the surface of a stainless steel plate strip having a sheet crown of 3% was finished using a grinding belt having two layers of abrasive material 6 fixed thereto, very good results were obtained.

することができる。 In the above explanation, the present invention was mainly applied to a grinding belt for finishing the surface of stainless steel plate strips, but the present invention could also be applied to grinding belts used for finishing the surface of steel plates, copper plates, and other metal plates. Needless to say, I have nothing to say. Furthermore, in the above embodiment, the abrasive material of the same particle size is fixed in a single layer on both sides in the width direction of the base material and in two layers in the center, but the present invention is not limited to this. not,
Abrasives with different particle sizes may be used, or the base material may be configured to have multiple layers in order from one layer to two layers to three layers from both sides in the width direction toward the center. Furthermore, the range of single layer and multilayer, type of abrasive, particle size, etc. can be selected as appropriate depending on the condition of the strip to be ground.

果大である。 As is clear from the above explanation, in the abrasive belt according to the present invention, the abrasive material is fixed in a single layer on both sides in the width direction, and in multiple layers in the center part, thereby creating a difference in height. Therefore, it can be used not only for steel plate strips and other metal plates, but also for stainless steel plate strips, which often require high flatness.
Since surface defects can be removed and the thickness in the width direction can be made almost uniform, it is highly effective in practical use.
