Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the shape of the body of a rolling roll for rolling a metal plate.

[Prior Art] Metals such as gold, silver, copper, and aluminum and their alloys are rolled using two or four stages of rolling rolls. These rolling rolls consist of a body that contacts the metal or alloy plate to be rolled and a shaft neck that rotatably supports the roll.The body may be formed into a straight cylindrical shape or The diameter of the center part is made slightly larger than that of both ends, and the body part is formed into a shape having a so-called roll crown in consideration of elastic deformation. The roll having this roll crown has a diameter that decreases from the center to both ends so that the surface of the body draws a gentle curve.

[Problem to be solved by the invention] When using conventional rolling rolls to roll various metals and alloys, a part of the material to be rolled adheres to the surface of the rolling roll, and this deposit is then rolled. There was a problem in that the phenomenon of adhesion to the surface of metal or alloy plates occurred.

In order to avoid the problem of deposits on the surface of the rolling roll adhering to the surface of the metal or alloy plate that is subsequently rolled, it is desirable to replace the rolling roll every time the metal or alloy of the material to be rolled changes. , it is not easy to replace the rolling rolls. Therefore, a jig for polishing the rolls is usually inserted between the rolls, and the roll polishing of the body is performed while rotating the rolls. Since polishing powder and the like remain on the roll surface after this polishing, these polishing powders and the like are removed using an organic solvent or the like.

However, at this time, there was a problem in that organic solvents containing polishing powder and the like flowed from the center of the body to both ends of the body, damaging the bearings of the roll chock.

The object of the present invention is to provide a rolling roll that prevents harmful substances such as organic solvents from entering the roll choke.

[Means for Solving the Problems] In order to solve the above problems, in the rolling roll according to the present invention, a solvent discharge groove is provided in the body,
This is a stopper to prevent organic solvents etc. from entering the roll chocks.

[Function] In the rolling roll configured as described above, even if an organic solvent or the like is used to remove polishing powder generated during polishing, the organic solvent containing the polishing powder or the like does not flow into the roll chock portion.

[Example] An example will be described with reference to the drawings. In FIG. 1, a rolling roll 10 is made up of a body part 12 and a shaft neck part 14, and the body part 12 is made up of a center part 12a and an end part 12b. There is. The diameter of the end portion 12b is
The body portion 12 is cut using a cylindrical grinder or the like so that the diameter is slightly smaller than the diameter of the central portion 12a. In this way, the diameter of the end portion 12b is adjusted to the center portion 1.
The reason why the diameter is slightly smaller than that of 2a is to maintain the uniformity of the roll surface even if the roll polishing of the body is continued for a long period of time, which is done by inserting a jig for polishing rolls between the rolls. This is to make it possible.

In the case of this example, the roll width is 200mm and the roll diameter
A cylindrical grinder was used to cut a 150 mm rolling roll, and the shape was formed into a shape with a width of 10 mm at the end portion 12b and a diameter difference of 6 mm between the center portion 12a and the end portion 12b. The material of this rolling roll is JIS
-Equivalent to SUJ2.

Furthermore, in this embodiment, a groove width s is provided at the end of the central portion 12a.
A groove 16 of = 3 mm and depth = 2 mm is cut. By cutting the groove 16, a wall portion 18 is formed on the outside thereof to prevent organic solvents and the like from flowing out.

The rolling roll formed as described above was used for a long period of time while the central portion 12a was polished each time it was used, but the uniformity of the surface of the central portion 12a was maintained and no damage to the roll chock occurred.

Organic solvents used during roll polishing are stored in groove 1.
6 and falls downward, and does not flow over the wall 18 to the roll yoke. Therefore, it is clear that the groove 16 serves as a stopper for preventing solvent from entering the roll chock when using a solvent after polishing the roll.

In the case of this embodiment, the bottom of the groove 18 was made flat, but
Similar effects can be obtained even if the groove 18 is formed into a V-shape or a U-shape.

[Effects of the invention] Since the present invention is configured as explained above, even if an organic solvent or the like is used for polishing the rolling roll, the organic solvent containing polishing powder or the like will not flow into the roll chock. This has the effect of making it possible to stably roll metal or alloy plates over a long period of time. Therefore, the invention of the present application makes a great contribution to industry.
