COATING APPARATUS FOR THE ANTI-CARBURIZING AGENT}

Particularly, in the case of carburizing treatment for making metal products such as steering wheel, gear, pinion, roll, piston, etc. to have a certain hardness, specific parts are carburized. The present invention relates to a coating apparatus for applying a carburizing prevention liquid to a specific part so as to prevent the processing and to maintain the original property of the specific part for the post-processing such as cutting and grinding.

In general, the main component of the solvent-based carburizing prevention liquid has a high specific gravity and has a high viscosity, so that it exists in the form of a high concentration solution or paste, and in order to apply it, a worker is applied with a brush or kneaded with a brush. That was done by hand,

In the coating apparatus for applying the anti-carburizing liquid of the present invention, it is possible to apply a portion to be carburized more finely by a receiving tank provided so that only a specific portion to be carburized is prevented,

In addition, in order to prevent the solid-liquid separation caused by the main component of the carburizing solution having a high specific gravity, the carburizing solution is mixed by the agitator in the storage tank to prevent the precipitation of some of the carburizing solution components at a constant concentration. Can be applied by

In addition, the carburizing prevention liquid can be more efficiently utilized by circulation means for supplying the carburizing preventing liquid from the storage tank to the holding tank and recovering the carburizing preventing liquid overflowed from the holding tank.

First of all, the risk of fire and safety accidents caused by the carburizing solution can be automated by various modifications and modifications by the coating device for applying the carburizing solution according to the present invention. It relates to a coating device for applying a carburizing prevention liquid that can escape from the risk of accidents and the like.

In general, metal products such as steering wheel, gear, pinion, roll, piston, etc. among metal materials generally have carbon in the metal material in order to have a certain hardness. Many carburizing treatments are used to infiltrate and obtain hard properties, ie the required hardness.

However, in this carburizing process, a specific part of the metal material must be kept to be ductile for post-processing such as cutting and grinding. Therefore, for this purpose, a specific part of the metal material prevents the carburizing process, thereby performing post-processing such as cutting and grinding. To facilitate this, a specific part of the metal material is applied with the carburizing agent.

Solvent carburizing solution used for this purpose is solid solution separation phenomenon that main component and diluent of carburizing solution is separated at the upper and lower part of container due to high specific gravity, and it sticks quickly in contact with air. It was inconvenient to focus so much on what you do,

In addition, due to the high viscosity of the carburizing agent, it is not easy to apply by spraying because it exists in the form of high concentration liquid or paste. Because of poor work efficiency

In addition, it is difficult to maintain the hardness of the parts to be carburized because the precision of applying the anticarburizing solution to the exact application point is insufficient, or the parts to be softened are carburized, making it difficult to process after cutting and grinding. There was a problem,

In addition, the diluent for diluting the solvent carburizing solution is flammable, which may cause hallucination and fire, and thus exposure to the hallucination action and fire risk caused by the diluent when manual labor is applied as described above to apply the carburizing solution. There was a problem that it is difficult to ensure the safety of the worker.

Therefore, Korean Patent Publication No. 1995-0032690 (published on Dec. 22, 1995) of Daewoo Electric Industry Co., Ltd.

Utility Model Publication No.1994-0007112 of KOREA SPACER INDUSTRY CO., LTD. (Announced on January 1,199,033) "Carburizing prevention cap for both carburizing heat treatment and shot blasting process"

Since the published patent and the notification utility model is not caused by a solvent-based carburizing solution, it is judged to be able to solve the above problems to some extent.

The carburizing cap needs additional processing such as fastening means, that is, a screw thread, etc., for the purpose of tight fit or fastening to keep a specific part of the metal material to be kept tight, and the dismantling work must be performed separately for this and the release thereof. It doesn't solve the problem that it's not easy,

In addition, according to the metal parts having a variety of shapes has not solved the problem of having to bear the economic losses to produce a carburizing prevention cap that fits the shape.

On the other hand, the registered utility model No. 0171723 (registered on Dec. 8, 1999) of Samsung SDI Co., Ltd. "graphite coating device of cathode ray tube" is provided by the pressure pump through a pressure regulating means between the pressure pump and the injection nozzle. Although the pumping slurry is continuously and fluidly transported, a graphite coating apparatus of a cathode ray tube formed of an auxiliary tube which bypasses an excess slurry through a bypass tube and feeds it back to a storage tank is proposed.

When the registered utility model has a high specific gravity and high viscosity of a main component such as a solvent-based carburizing prevention liquid as a coating device by spraying, it is difficult to apply the spray by the same spraying as the registered utility model. There is a problem in that it is difficult to apply the application is different from the registration utility model in that it should be.

In addition, Korean Patent No. 0327519 (registered on Feb. 22, 2002) "Immersion Surface Treatment Apparatus and Immersion Surface Treatment Method Using the Same" is used to purify a liquid material through a main tank having a liquid material to immerse an article and a main tank. It consists of a circulation mechanism to let

Dipping can effectively remove contaminants or bubbles, such as a collection of metal powder and paint particles, from the tank to treat the surface of the product with the liquid material, prevent the precipitation of paint particles, and raise the local temperature of the liquid material. It is also proposed to provide a device that can prevent and a method for treating a product with a liquid material by immersion using the device,

In order to apply the surface of the product to the liquid material by immersion according to the patent, the liquid material is formed in a certain direction through the circulation mechanism to remove contaminants or bubbles such as a collection of metal powder and paint particles from the tank, There is an advantageous effect that it is possible to prevent the precipitation of paint particles and the local temperature rise of the liquid material.

When the main component has a high specific gravity and high viscosity, such as a solvent carburizing solution, when forming a flow as described in the patent, the coating layer by the carburizing prevention solution applied to the surface of the metal material is not formed uniformly. Carbon penetrates into a specific area that should be prevented from carburizing and loses ductility for post-processing.

In the case of a liquid material having the same properties as the solvent-based carburizing preventing liquid, there is a problem that it is difficult to use a device such as the patent.
