Abstract

(57) [Summary] [Structure] In a polishing buff roll constructed by laminating buffs, a tilted ring 3 made of a rigid body such as metal or plastic is incorporated every time several buffs 2 are laminated. [Effects] When polishing is performed using the polishing buff roll of the present invention, instead of the conventional straight-line polishing marks, meandering polishing marks are formed at a very fine pitch, resulting in so-called blurred polishing. As a result, since scratches are less likely to occur, mirror polished plates with a #8 finish can be easily produced, which is a remarkable effect.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a buff roll for mirror polishing stainless steel plates and the like.

0002

[Conventional technology]

In recent years, the demand for so-called construction steel sheets for the interior and exterior of buildings has been rapidly increasing. In particular, demand for steel sheets with mirror-polished surfaces is growing rapidly. Especially stainless steel Since there are many mirror-finish materials made by polishing plates, this invention uses a stainless steel mirror-polished plate (hereinafter referred to as mirror-finishing plate). The explanation will be given by taking as an example the material (called "face material").

0003 The finish of the mirror material is made of fabric, cotton, polyester, etc., and the rotation axis is horizontal. The #700 finish is polished by a grinding wheel, and the #8 finish is finished by lapping after polishing with a whetstone. Separated. The polishing method for #700 finish is about 4 times more productive than that for #8 finish. However, because the polishing is done in a dry state, scratches called so-called feather grains remain. On the other hand, #8 finish is a higher quality finish that does not cause scratches.

0004 As a way to eliminate and reduce scratches, oscillate the horizontal axis roll horizontally. However, due to the heavy weight of the rolls, etc. Limited by the oscillation width and oscillation frequency, the scratches cannot be completely erased. I haven't reached that point yet. In addition, a wet horizontal roll polishing method is proposed in Japanese Patent Application Laid-Open No. 2-88164. However, this method has a straight polishing trajectory, so it is not possible to completely eliminate scratches. do not have.

[0005] Furthermore, in Japanese Utility Model Application Publication No. 57-43966, the boundary line of the disc member of the grinding roll is A grinding roll formed so as to be inclined with respect to the axial direction is disclosed. If the roll rotates at high speed, the tilted state may not be maintained due to centrifugal force. There is.

[0006]

[Problem that the idea aims to solve]

The present invention solves these conventional problems and uses horizontal rolls to produce mirror-like abrasives. To provide a polishing buff roll that prevents scratches that occur during manufacturing. With the goal.

[0007]

[Means to solve the problem]

This invention is a polishing buff roll constructed by stacking buffs. Each layer incorporates a rigid inclined ring made of metal or plastic. This is a buff roll for polishing characterized by the following.

[0008]

[Effect]

The present inventors have developed a #8 finish that does not cause scratches and a #8 finish that does not cause scratches. 700 As a result of comparing and examining various polishing methods, scratches do not occur with #8 finish. It was discovered that this is because the polishing trajectory is random. That is, with #700 finish Since the roll polishing direction is always constant, the polishing marks are easily noticeable.

[0009] From the above, horizontal rolls are recommended to reduce and prevent scratches on #700 finishing material. It may be effective to change the trajectory of one rotation from the conventional straight line type to a meandering type. It was estimated that this led to the present invention. FIG. 2 shows the polishing trajectory by the roll of the present invention. The polishing pattern of one buff roll is The amplitude W is shown by a curve of 2R tanθ, and the period T of one rotation of the roll is the rotation of the roll. The number varies depending on the feed speed of the material to be polished, and under normal horizontal roll polishing conditions, It will be about 2 to 10 mm. These serpentine grinding marks are formed at a very fine pitch. Since the tip of the buff actually has a width, conventionally it was visible in a straight line. As a result, the polished marks are blurred, making scratches less likely to occur.

0010 In addition, the problem with the above-mentioned Japanese Utility Model Publication No. 57-43966 is that the disk drive is prevented when the roll rotates at high speed. Addresses the issue where the boundary line of the workpiece cannot maintain its slope in the direction of the roll axis. For this reason, it is not enough that the boundary line is simply sloped when the vehicle is at rest. 2000 per minute Even when centrifugal force acts during high-speed rotation, the boundary line of the buff part oscillates from side to side. For this purpose, the presence of an inclined ring 3 as shown in FIG. 1 is essential. Configure like this If you do this, when the polishing buff roll rotates at high speed, the boundary line of the buff marks will be at least as large as Figure 2. As shown in the figure, the trajectory of W = 2R tanθ is drawn, and scratches are not generated as in the conventional case. There is no such thing as

[0011]

【Example】

An embodiment of the polishing buff roll of the present invention will be described based on the drawings. FIG. 1 is a sectional view of an embodiment of the polishing buff roll of the present invention. In Fig. 1, 1 is a roll shaft core, 2 is a cloth (buff), and several sheets of cloth 2 are laminated. Each time, an inclined ring 3 made of a rigid body such as metal or plastic is incorporated. It is. θ is the inclination angle of the inclination ring 3 with respect to the axis.

0012 Next, Figure 3 shows the #700 finished scratch when the inclination angle θ of the inclination ring 3 is changed. Shows the remaining status. As can be seen from Figure 3, if the inclination angle θ is less than 5°, it is too small and scratches can be prevented. It has no effect. Conversely, when the inclination angle θ exceeds 20°, the amplitude W=2R tanθ becomes large. , and newly zigzag scratches become noticeable, so it is necessary to set the appropriate θ. The range is 5-20°. Further, the upper limit of the amplitude W is preferably about 10 mm for the same purpose. Ma In addition, the outer diameter of the cloth may be approximately 600 to 700 mmφ.

[Effect of the idea]

As explained above, if polishing is performed using the polishing buff roll of the present invention, Nowadays, the grinding marks appear in a straight line, and now there are meandering grinding marks with a very fine pitch. # This has the remarkable effect that polishing plates with a 8-finish finish can be easily produced.
