Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polishing method capable of uniformly polishing uneven surfaces formed on various members such as building members formed by press working.

[0002]

2. Description of the Related Art Conventionally, an uneven surface formed on various members such as building members formed by press working, for example, an uneven surface formed on a wall plate formed by corrugating a steel plate in a cross section The polishing was done with a polishing machine equipped with polishing sheets such as polishing paper and polishing cloth, or puffs and polishing belts.

[0003]

In the conventional polishing method,
Since the concave and convex surfaces of the uneven surface of the member cannot be polished at the same time, it takes a long time to work, the work efficiency is poor, and there is a risk that a non-polished portion may occur near the boundary between the concave surface and the convex surface.

[0004]

SUMMARY OF THE INVENTION The present invention has been made by paying attention to such a conventional problem, and a shaping member is interposed on the back surface of an abrasive sheet to form a concave and convex surface of the member. It is an object of the present invention to solve the above-mentioned problems by polishing the polishing sheet so that the polishing sheet is uniformly brought into close contact with the convex surface.

The present invention is directed to a polishing sheet, a shaping member provided on the back surface of the polishing sheet and having flexibility and elasticity with a required thickness, and a pressing force applied by a required pressure stacked on the shaping member. It is a method of polishing an uneven surface of a member, which comprises performing polishing using a polishing device including a pressure plate.

[0006]

In the polishing method according to the present invention, the polishing sheet for polishing the uneven surface of the member is pressed by the pressure adjusting plate via the flexible and elastic shaping member provided on the back surface thereof. The shaping member bites into the concave surface to bring the polishing sheet into close contact with the concave surface as well as the convex surface, so that the concave surface and the convex surface can be simultaneously and uniformly polished, and the vicinity of the boundary between the concave surface and the convex surface can be surely polished. As a result, work efficiency can be improved.

Further, the polishing method is very easy to manufacture because it has a simple structure and is easy to manufacture, and moreover, the polishing apparatus made of a relatively inexpensive material is simply attached to the conventional apparatus. Yes, there is no increase in the unit price of man-hours.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on an embodiment shown in FIG. The uneven surface 4 of the corrugated wall plate 3 fixed by the fixing jig 2 on the polishing table 1 and formed by pressing a steel plate
A; a shaping member 6 made of a polishing cloth and a sponge provided on the back surface of the polishing cloth 5 and having a required thickness and flexibility and elasticity.
And a pressure adjusting plate 8 made of a steel plate, which is stacked on the shaping member 6 and has a required weight 7 placed on the back surface thereof.
After attaching the polishing cloth 5 to the uneven surface 4 by contacting it, the weight 7 is placed on the back surface of the pressure adjusting plate 8, and the polishing device 9 and the weight 7 are attached by an appropriate mechanical device (not shown). The concavo-convex surface 4 of the wall plate 3 is polished by performing a horizontal reciprocating motion (reciprocating motion from the back to the front in the drawing). After polishing, remove the weight 7 and remove the wall plate 3.

In this case, in the polishing method according to the present invention, the polishing cloth 5 for polishing the uneven surface 4 of the wall plate 3 is adjusted via the flexible and elastic shaping member 6 provided on the back surface thereof. Since the pressing plate 8 presses, the shaping member 6 bites into the concave surface 4 ″, and the polishing cloth 5 is brought into close contact with the concave surface 4 ′ and the convex surface 4 ″, so that the concave surface 4 ′ and the convex surface 4 ″ are simultaneously formed. Further, the work efficiency can be improved by uniformly polishing and further reliably polishing the vicinity of the boundary between the concave surface 4'and the convex surface 4 ".

Further, the polishing method is very easy to manufacture because it has a simple structure and is easy to manufacture. Moreover, the polishing apparatus 9 made of a relatively inexpensive material is simply attached to a conventional apparatus. Therefore, the unit cost of the man-hours for manufacturing will not increase.

Although the polishing cloth 5 is used for the polishing device 9 in the above embodiment, a polishing sheet such as polishing paper or polishing cloth paper having the same characteristics may be used instead of the polishing cloth 5. . Further, the shaping member 6 of the polishing device 9 is made of sponge. The purpose of the shaping member 6 is to dent into the concave surface 4'of the wall plate 3 which is a member when the pressure adjusting plate 8 is pressed, so that the polishing cloth 5 has a concave surface. 4'and close to the convex surface 4 ", and it is to return to the original shape when the pressing force is removed, and if it has the flexibility and elasticity required for that purpose, other than sponge It may be a material, for example a foamed synthetic resin having the same characteristics as a sponge.

Further, the weight 7 is placed on the back surface of the adjusting plate 8 in order to press the shaping member 6 via the pressure adjusting plate 8. However, a plurality of spring coils may be provided instead of the weight 7. Further, the wall plate 3 was fixed to the polishing table 1, and the polishing device 9 and the weight 7 were horizontally reciprocated to perform polishing.
Alternatively, the weight 7 may be fixed, and the polishing table to which the wall plate 3 is fixed may be horizontally reciprocated. It goes without saying that the horizontally reciprocating polishing table naturally has a different structure or shape from the polishing table 1 shown in the figure.

[0013]

Since the present invention has the above-mentioned structure, it has the following effects. That is, the uneven surface of the member, which has been difficult in the past, can be uniformly ground, and the working efficiency can be remarkably improved. Therefore, it contributes to cost reduction of parts. Further, it is extremely easy to carry out, and it is possible to prevent an increase in the unit price of the number of man-hours, which is an extremely excellent working method. Also, by providing this grinding method to other companies, it will contribute to the increase of corporate profits.
