Description

[Detailed description of the invention] Wire descaling device Technical field The present invention relates to the work of drawing and finishing wire, and in particular, it is easy to remove scale. The present invention relates to a wire scale removal device shown below as a device for removing scale.

Background technology Widely used today to remove scale and clean wire surfaces. various chemical, mechanical (including fluid mechanics) or other devices; There are combinations of these.

However, it is possible to enhance the properties of the descaled surface and improve productivity. , reduce production costs, and extend the life of the scale removal equipment itself. No such descaling methods and devices are known today.

For example, mechanical and chemical wire descaling devices used today There are some types that combine various types of processing equipment. This is the bending row that performs the first scale removal. and a pair of rollers located downstream of this bending roller to remove any remaining scale. An electrolytic tank equipped with electrodes, a washing cypress to remove electrolysis residue, and a cabinet-like (For example, Japanese Patent Application No. 52-3192, Filed on March 22, 1977, Classification 12C222, 3, Published on July 30, 1979 No. 54-2134).

However, the above-mentioned equipment takes up a large amount of production, floor space, and consumes a large amount of energy. waste and pollute the environment through electrolyte exhaust and waste liquid.

In addition, conventionally used wire scale removal equipment is a mechanical and chemical scale removal device. Chemical removal methods are used to remove scale from wires. Sulfuric or hydrochloric acid solutions have been used as medium to pickle scale (e.g. “Finishing and cold rolling production of steel materials JN, 1. Sheltyl, Moscow , Metal Publishing.

1956 p. 44 (USSR)).

However, pickling in acidic solutions is uneconomical and according to industrial ecological standards. However, it is not desirable because it contains gases that are harmful to humans. In addition, stainless steel, tools, etc. Pickling wires made of special materials is very time-consuming, so pickling productivity is limited. It will drop.

Devices that mechanically remove scale from wire, such as needle mills and shotguns Bending rollers combined with brushes or wire brushes are known (for example, Japanese Patent Application No. 49-66295 1 Class 12C222, 3 June 10, 1974 Application No. 53-31448, published on September 2, 1978, France Patent Application No. 2,438.507 1 Class 21B45100゜1980, Others ).

However, the above-mentioned scale removal equipment cannot be used for many important components that are exposed to rapid wear. are at a disadvantage in that they have elements, and this reduces the certainty of action. I'm letting it go down. In addition, during the work the above-mentioned equipment should be protected from the accumulation of dust around it. must be reliably isolated from the surrounding environment in order to This applies high gravitational loads to the descaling surface, which causes cold peening to the metal material being processed. This will result in the addition of additional information. This causes the mechanical properties of the metal to deviate. .

Additionally, mechanical wire descaling devices that use magnetic abrasive powder under a magnetic field are known (e.g. Soviet inventor's certificate No. 787,131, C1l B21B45 104゜B21C43104, published on December 15, 1980, or Soviet inventor's certificate No. 422.494, C1, B21C43104, 821B45104, 197 Published on April 5, 2015, 9th grade).

For example, Soviet inventor's certificate No. 422.494 CI.

Scale removal equipment using B21C43104 and B21B45104 1. Placement is non-magnetic It has a cylinder-shaped storage chamber made of magnetic material, and this storage chamber stores magnetic abrasive powder. A ring-shaped electromagnet is placed around the storage chamber. Magnetism caused by this electromagnet The field gives the abrasive powder a magnetic effect and prevents the abrasive powder from loosening.

A piston is placed inside this storage chamber, and the piston compresses the magnetic abrasive powder. As soon as the abrasive powder becomes dirty, the abrasive powder is periodically transferred to be replaced.

The wire to be descaled passes through the end of the storage chamber and moves in the axial direction of the storage chamber. During this process, the wire interacts mechanically with the abrasive powder, and the surface of the wire changes due to the action of the abrasive powder. It detaches from the removed scale. In this case, the abrasive powder is transferred to the surface of the wire by the magnetic field. Mechanically the wire by orienting its shaped end towards the face and also being compressed into the piston to put pressure on.

This device offers many advantages over the chemical-mechanical wire descaling devices described above. have For example, it is ecologically clean, has a small size, and has low operating costs. Also wire table No cold peening is applied to the surface.

However, this device does not fill the storage chamber with abrasive powder or discharge used abrasive powder. There is a problem in that the work to do this is extremely troublesome. Because the abrasive powder is stored When pressurized by the piston in the longitudinal direction of the axis of the chamber, the friction applied to the inner wall of the storage chamber This is because the abrasive powder is subjected to great resistance due to friction. As a result, the piston moves The piston and the inner wall of the storage chamber may wear out more quickly. There is. These reduce the overall reliability of the device's operation. Sara The wire being processed must be stopped every time the abrasive powder is filled or discharged. No. This reduces the productivity of the equipment and makes it even more difficult to use today's impractical for use in descaling transfer lines and continuous wire drawing equipment. Make it possible.

Disclosure of invention The first object of the present invention is to fill and discharge abrasive powder into a storage chamber with very little effort. The purpose of the present invention is to provide a descaling device that can This may cause the component to malfunction (or become worn out prematurely). It can be prevented. In addition, when filling and discharging abrasive powder with this device, No need to stop ear movement. These features ensure the operation of the device. This equipment has been developed to improve productivity by combining scale removal and drawing transfer lines. Can be applied to high continuous work.

This purpose is achieved by a wire descaling device as follows.

In other words, this device includes a storage chamber filled with magnetic abrasive powder and an electric current applied to the magnetic abrasive powder. An electromagnet that forms a magnetic field to create a magnetic effect and a device that discharges used magnetic abrasive powder. A wire descaling device comprising at least two storage chambers. The apparatus for discharging the used magnetic abrasive powder has at least two outlets. each of these outlets is located at the bottom of the corresponding compartment and These exits have gates to prevent abrasive powder from falling from the storage chamber under their own weight. The electromagnet whose magnetic field magnetizes the magnetic abrasive powder has a plunger in every compartment. They are characterized by being arranged so that they move in opposition to each other.

The housing consists of at least two compartments, each equipped with an outlet for the abrasive powder. By providing a storage chamber, magnetic abrasive powder can be removed without stopping the movement of the wire. It can be changed. This is because the compartments can be activated alternately. sand That is, the polishing powder is magnetized by an electromagnet in one compartment. When the scale is removed from the ear, the electromagnet is de-energized and used in another compartment. The used abrasive powder is replaced with newly filled abrasive powder. Then the function of the compartment take turns.

Also, the outlet of the abrasive powder is located at the bottom of the corresponding compartment, which makes the abrasive The grinding powder can be naturally discharged from the storage chamber under its own weight. As a result, abrasive powder was found in the storage chamber. There is no need for a piston to be pushed in by the user, and the phenomenon of the piston becoming inoperable is also eliminated. Ma This also eliminates premature wear and failure, and eliminates abrasive powder filling and emptying operations. It becomes simple and the reliability of the operation of the device can be increased.

Gates are installed at all abrasive powder outlets to prevent abrasive powder from naturally discharging. The charging and discharging of the abrasive powder can be controlled by this. sand That is, this gate is only opened when the corresponding compartment is emptied and the device is not activated. This is because the automatic discharge of the abrasive powder is prevented by being closed while the abrasive powder is closed. By this, The stability of the device during continuous operation is further ensured.

arranging electromagnetic plungers moving opposite each other in each compartment; First, the operation of each compartment can be made independent of the other compartments. , Second, the abrasive powder in each compartment is not only affected independently by the magnetic field, but also mutually. It can be placed under mechanical compression created by adjacent electromagnetic plungers. this This in turn can improve the descaling performance of the wire, especially for special Wires made of high quality wires or wires covered with scales that adhere to metal surfaces with strong force. In this case, the scale performance can be improved.

All of the above-mentioned features thus apply to continuously moving wire descaling. Provides stable operation in the device and good wire descaling process.
