JPS6034263A - Polisher for wire rod and bar work - Google Patents

Abstract

PURPOSE:To make a work surface polishable favorably without scratching a wire rod and the like, by passing the wire rod and the like through the inside of a grit tank through magnetic attraction by a magnetic material, while polishing them with driction against the grit and eliminating the magnetic attraction by a demagnetizer. CONSTITUTION:A wire rod or a bar work B enters the inside of a grit tank 1 in a body 20 of a polisher A from an inlet 2, and its surface is polished ample enough during a while passing through a grit layer via a guide 3. In addition, the wire rod or the bar work B reaches to a magentic field layer 4 produced at a coil situated in the central part of the grit tank 1 and makes those of black, rust, dust and so on removed from the surface stick to an electrode of a magnetic field layer 4 at a time when it passes through the layer 4 as producing friction against grit whereby the magnetism being excited is demagnetized because of passing through inside the coil of a demagnetizer 5 and conveyed outside by way of an outlet 6. Thus, the surface of the wire rod or the bar work B can be finely finished to perfection without scratching it.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a general wire or bar polishing apparatus.

The conventional method of polishing wire or bar material is to forcibly pull it through brushed rollers.
There is a method using a device that polishes the surface of the wire or bar, but the surface of the wire or bar may be scratched by the brush, the polished finish may be uneven, and magnetism generated during the polishing process may occur. It was difficult to remove.

The present invention provides a device that beautifully completes the polished finish without causing scratches or stiffness on the surface of the wire or bar, and eliminates the magnetism that is imparted to the wire or bar during polishing work. The purpose is to

The wire or bar polishing apparatus according to the present invention includes a plurality of magnetic bodies in a grid tank, and uses the adsorption force generated by the magnetic bodies to pass the wire or bar into the grid tank, After the grid material in the grid tank and the wire or bar are polished by friction, a demagnetizing device is provided so as to eliminate the attraction force due to magnetism generated in the wire or bar. It is a feature.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The wire and bar polishing apparatus according to the present invention will be described in detail below based on one embodiment thereof. FIG. 1 is a front view of the device, and FIG. 2 is a side view thereof. In both drawings, the internal parts are partially shown in cross section for the purpose of explanation. A is a wire or bar polishing device, and as shown in FIG. 1, a wire or bar B passes through the device from right to left. Although there is a separate device for pulling the wire or bar B, it will be omitted. Reference numeral 1 denotes a Grisoto tank, which is filled with a grid C made of crushed metal grains melted and cast in a cupola or other suitable furnace. As shown, the glyph 1

is attached. There is a magnetic field layer 4 generated by a coil in the center of the tank, in which a large number (an odd number) of N poles and S poles are arranged alternately. pass. A degaussing device 5 consisting of a coil is installed on the left side of the Glysotho tank 1, leading to a wire or bar outlet 6. A vibration motor 21 is attached to the lower center of the grid tank 1, and grid discharge ports are provided at the bottoms of both left and right sides of the vibration motor 21.

Glyphs 1.C received C and concentrated on the train pipe 9 at the tip of the center lower part. C is installed in the bucket conveyor tank 10 (at the top by a bucket conveyor (not shown))
- and is then poured into the grid tank 1 again from the grid 11. Reference numeral 12 denotes an inspection opening in the grid tank 1, and indicates a door 13 and a handle 14 that can be opened and closed. A plurality of springs 15 support the grid tank 1. 16 is an electric motor for driving the bucket conveyor in the brush conveyor tank 10, and 17 is a manual handle. Note that a blind lid 18 is provided at the bottom of the front F conveyor tank 10. Reference numeral 19 denotes an exhaust pipe, which is installed at the top of the main body 20 of the apparatus A and connected to a dust collector (not shown).

The operation of the wire or bar polishing apparatus A constructed as described above will now be described. As shown in the figure, a grid tank 1 is installed in the main body 20 of the apparatus A from the wire or bar entrance 2.
The surface of the wire or bar B that has entered the grid tank 1 is sufficiently polished while passing through the layer of glyphs 1-C filled in the grid tank 1 via the kite 3. Furthermore, the wire or bar B reaches the magnetic field layer 4 generated by the coil in the center of the grid tank 1, and in the process of passing between a large number of alternately arranged north and south poles, the above-mentioned Grid C and friction (
In order to deposit black scale, rust, dust, dirt, etc. removed from the surface of the wire or bar B on the electrode, it passes through the coil of the degaussing device 5 installed at the end. By doing so, the magnetism of the wire or bar B is completely erased, and it exits the main body 20 via the wire or bar outlet 6.

In addition, regarding demagnetization of the grid material, the magnetic pole is changed according to the operating time, and at the end of the operation, an electrical switch is made instantaneously, and the grid material can be demagnetized by being energized for a certain period of time.

Furthermore, the degaussing device has a strong magnetic force (cylindrical shape), and can demagnetize a wire or bar by passing it through the center of both magnetic poles. The grid is provided to prevent magnetization of the wire or bar and to increase the attraction force of the grid.

Therefore, by using the wire or bar polishing apparatus according to the present invention, not only can the surface of the wire or bar be polished completely and beautifully without any scratches, but also the polishing process can be It is possible to completely eliminate the magnetism contained therein quickly and easily. Furthermore, the wire or bar material can be polished regardless of whether it is a magnetic material, non-magnetic material, or non-magnetic material, and the grid (5) can be recycled and used, and has great effects in preventing pollution.
