Abstract

PURPOSE:To prevent the occurrence of a scratch on the surface of a piece of wire by making said piece of wire pass through a grit vessel by means of the adsorbing force generated by a magnetic body provided in said vessel and polishing said wire. CONSTITUTION:A large number of grit material C are filled in a grit vessel 1, forming a layer, while in the central part of the vessel 1 is provided a layer of magnetic field 4, in which a number of N and S poles are alternately arranged and coils 7 for generating magnetism are placed under these poles, and through which a piece of wire B passes. The piece of wire B is introduced from an inlet 2 and through a guide 3, polished while passing through the layer of the grit material C filled in the grit vessel 1 and, then, passes through the layer of magnetic field 4 while being rubbed with the grit materials C and, finally, it loses magnetism by passing through a magnetic erasing device 5. Due to the method as stated above, the occurrence of a scratch can be prevented while magnetism, rust, dust, etc. can be also removed easily and rapidly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a general method for polishing a wire or bar.

Conventionally, as shown in FIG. 1, as a method of polishing a wire or bar B, there is a method in which the wire or bar B is forcibly pulled and passed between brushed rollers 02 to be polished.

However, in this method, the surface of the wire or bar B was easily scratched by the brushed roller 02 and the like, and the polished finish was uneven.

The present invention provides wire rods or rods that do not cause scratches on the surface of wire rods or rods, are polished without unevenness, and are not only finished beautifully, but also eliminate magnetism that is imparted to wire rods and rods during polishing work. The purpose is to provide a method for polishing materials.

The method for polishing a wire or bar according to the present invention includes a plurality of magnetic bodies in the glyph 1 to a tank, and the wire or bar is passed into the grid tank using the adsorption force generated by the magnetic bodies. and after the glyph 1 to material in the grid tank and the wire or bar are polished by friction, the attraction force due to magnetism generated in the wire or bar is erased. There is.

Embodiments of the method for polishing a wire or bar according to the present invention will be described in detail below. Figures 2 and 3 are for explaining the main points of the apparatus based on the method of the present invention, and show the interior of the grid tank inside the wire or bar polishing apparatus A, which has a magnetic generation coil 7 installed at the bottom. It is. The grid tank 1 is filled with a large number of grid materials C in a layered manner. still,
Grit material C is made by crushing metal grains melted and cast in a cupola or other suitable furnace. 2 is the wire entrance,
A guide 3' for the wire or bar B to pass through is also provided. In the center of the grid tank 1, there is a magnetic field layer 4 in which a large number (an odd number) of N poles and S poles are arranged alternately, and a magnetic field generating coil 7 is installed in the lower part. Material B passes through. 5 is a degaussing device through which the wire B passes, and the main body is a coil. Immediately after the device 5, an outlet 6 for wire or bar material is provided.

Now, the wire rod or bar B is sufficiently polished while passing through the layer of the grid material C filled in the grid tank 1 from the wire rod 2 through the guide 3. Further, the wire or bar B reaches the magnetic field layer, and passes through the magnetic field layer 4 in which the N poles and S poles are arranged alternately and a coil 7 for generating magnetism is installed at the bottom while rubbing against the grid material C. Finally, the wire or bar B is completely demagnetized by passing through the coil of the degaussing device 5, and exits from the polishing device A through the outlet 6.

Therefore, by using the wire or bar polishing method according to the present invention, the surface of the wire or bar can be polished completely and beautifully without any scratches.

In addition, magnetism, rust, dust, etc. that may be present during polishing work can be completely removed quickly and easily.

Figure 1 is an explanatory diagram of the conventional polishing method for wire or bar material, Figure 2
The figure is an embodiment of the wire or bar polishing method according to the present invention, and FIG. 3 is a partial cross-sectional view of the central portion of FIG. 2.
