In addition, the rotation unit 200 is connected to the motor unit 300 to receive power from the motor and rotates, and the rotational force of the rotation unit 200 can be adjusted by controlling the power of the motor.

The processing unit 400 will be described with reference to FIGS. 4 and 5 .

Unlike the conventional polishing device in which a single processing member for processing the inner surface of the conventional gasket 10 existed in the processing unit 400, the upper processing unit 410 and the lower part are spaced apart at regular intervals in the vertical direction. It consists of study (420).

Referring to FIG. 5, the upper processing unit 410 includes an upper support unit 412 extending in the longitudinal direction and an upper processing unit 411 protruding vertically downward from the upper support unit 412,

That is, the upper processing member 411 comes into contact with the upper surface of the gasket 10, and the lower processing member 421 comes into contact with the lower surface of the gasket 10 at the same time, so that both sides of the gasket 10 rotate while the gasket 10 rotates. It is characterized by this processing.

Processing of both sides means that the upper and lower surfaces of the gasket 10 are processed. Therefore, unlike the conventional gasket 10 processing device in which the processing device must be repeatedly driven twice or more to process both sides, power (power) is minimized by processing both sides of the gasket 10 at once, and manufacturing cost and processing time are minimized. It has the effect of increasing productivity by saving.

It is preferable that the ends of the upper processing member 411 and the lower processing member 421 contact the gasket 10 have a pointed shape. This is because stress is locally generated in the sharply pointed part compared to the flat part, enabling precise processing.

The upper deburring unit 610 and the lower deburring unit 620 have the same shape, have flat inner surfaces, and are coupled in an 'I' shape with their inner surfaces facing each other at a predetermined interval.

Referring to FIG. 6 , the upper deburring unit 610 and the lower deburring unit 620 are coupled to each other by a bolt B, and the coupling distance may be adjusted. This is to allow processing of various types of gaskets 10 since each gasket 10 has a different height. Therefore, since the deburring unit 600 can remove various types of burrs from the gasket 10 , versatility is increased.

In addition, the burr removal unit 600 includes a cutting edge unit and a guide unit, which, for convenience of explanation, includes a first cutting edge unit 615, a second cutting edge unit 625, a first guide unit 614, and a second guide unit. Divide into (624) and explain.

Including, the configuration of the lower deburring unit 620 is the same as the configuration of the upper deburring unit 610, but there is only a difference in the fastening position, so the upper deburring unit 610 is mainly described to prevent overlapping explanation. do.

The first upper fixing part 611 is preferably formed with a hole for bolting with the second upper fixing part 621, and the upper deburring part 610 and the lower deburring part 620 are fastened through the hole. The gap can be adjusted and allows the gasket 10 to pass through.

The first lower fixing part 613 has a hole formed to be bolted to the second lower fixing part 623 and has the same shape and function as the first upper fixing part 611 described above.

The first removal end 612 has a flat inner surface and extends from the first upper fixing part 611 toward the first lower fixing part 613 at one point on the inner surface of the first removing end 612. A first cutting edge portion 615 and a first guide portion 614 facing each other are formed.

The inner surface of the first removal end 612 is adjacent to the upper surface of the gasket 10, and the first cutting blade 615 comes into contact with the upper surface of the gasket 10, and the second removal end 622 also includes the gasket ( Adjacent to the lower surface of 10), the second cutting edge portion 625 is brought into contact with the lower surface of the gasket 10.

Accordingly, when the upper deburring unit 610 and the lower deburring unit 620 are coupled, as shown in FIG. The burr protrudes beyond the distance at which 620 is spaced apart, and the burr is removed while being cut by the first cutting edge part 615 and the second cutting edge part 625.

Accordingly, there is an effect of smoothly processing the surface of the processed gasket 10 .

In addition, referring to FIG. 9 , the removed burr is accommodated in the space of the upper deburr removal unit 610 and the lower deburr removal unit 620 by the first guide unit 614 and the second guide unit 624, and the gasket ( When processing the burr of 10), the cut burr does not fall into the working environment and the burr 13 can be collected.

This can reduce the time required to clean the chip 12 when the chip 12 bounces everywhere.

In addition, the first cutting edge part 615 and the first guide part 614 are spaced apart from each other at a predetermined interval, and a gap is provided to accommodate the burr in the upper deburring part 610, and the first guide part 614 is placed on the inner side. It has a feature of guiding to prevent the burr 13 from leaking out to the outside.

Referring to FIG. 1 , a cutting oil supply unit 700 for supplying cutting oil to the gasket 10 is formed.

Cutting oil refers to an oil agent used to aid cooling or lubrication in the process of metal processing, and the cutting oil supply unit 700 is composed of a body in which cutting oil is stored and a nozzle for spraying cutting oil, plays a role in spraying and supplying Accordingly, in the process of processing, the temperature of the gasket 10 is lowered, and lubricity is provided so that smooth processing is performed.

In addition, the gasket 10 of the present invention is used to maintain airtightness so that the filling, gas or cooling water does not leak or to prevent the inflow of external contaminated substances, and is mainly used in the pipe connection or internal combustion engine, which is vulnerable to corrosion. There are downsides.

To prevent this, referring to FIG. 10 , a spray unit 800 for forming an anti-corrosion coating layer is shown.

The spray unit 800 includes a storage unit 810 for storing the coating composition and a spray unit 820 for coating the gasket 10 by spraying the coating composition on the gasket 10 to form a coating layer.

The injection unit 820 may coat the gasket 10 with a coating composition in a spray form,

The coating layer (not shown) is coated using a coating composition, and the coating layer using the coating composition may exhibit an anti-corrosion effect. Specifically, a coating layer is formed on the surface of the gasket 10 by the coating layer to prevent the gasket 10 from being exposed to the outside, and since it contains a metal having a higher ionization tendency than the gasket 10, the corrosion can be prevented.

More specifically, the coating composition of the present invention is a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds;

[Formula 1]

Here, n is an integer from 1 to 100.

When a coating layer is formed on the surface of the gasket 10 using the coating composition of the present invention, the adhesion to the gasket 10 is excellent, the coating layer is not easily peeled off by external force, and the ionization tendency is higher than that of the gasket 10. As it contains a high metal compound, an excellent anti-corrosion effect can be exhibited.

Specifically, the siloxane-based compound not only exhibits excellent adhesive strength with the gasket 10, but also maintains the viscosity of the coating composition at a certain level to increase formability and stability.

The metal compound serves as an erosion and corrosion inhibitor that blocks contact with moisture, salt or oxygen. Here, as the metal compound, a metal having a higher ionization tendency than iron may be used to act as an erosion and corrosion inhibitor. That is, metals or alloys such as aluminum (Al), magnesium (Mg), and zinc (Zn) may be used, and zinc (Zn) is mainly used.

A particle size of the metal compound may be 0.1 to 10 μm. If the particle size of the metal compound is 0.1 μm or more, the manufacturing cost of the metal compound can be reduced, and if the particle size of the metal compound is 10 μm or less, the metal particles can be uniformly dispersed.

The organic solvent is selected from the group consisting of methyl ethyl ketone (MEK), toluene, and mixtures thereof, and preferably methyl ethyl ketone may be used, but is not limited to the above examples.

The amine compound may include a modified aliphatic amine or tertiary amines, and specifically, trimethylamine or aniline may be used. The amine compound may be included in the coating composition to prevent cracking or peeling of the coating film. That is, the effect of preventing cracks or peeling of the coating film due to use by increasing the adhesive strength of the coating layer is excellent.

The coating composition may further include a stabilizer as other additives, and the stabilizer may include a UV absorber, an antioxidant, and the like, but is not limited to the above examples and may be used without limitation.

For forming the coating layer, the coating composition is more specifically a siloxane-based compound represented by Formula 1; organic solvents, metal compounds and amine compounds.

The coating composition may include 40 to 60 parts by weight of the siloxane-based compound represented by Formula 1, 20 to 40 parts by weight of a metal compound, and 5 to 15 parts by weight of an amine compound, based on 100 parts by weight of the organic solvent. In the case of the above range, a synergistic effect is expressed to the extent that the water repellency effect due to the interaction of each component is of critical significance, and when it is out of the above range, the synergistic effect is rapidly reduced or almost nonexistent.

More preferably, the viscosity of the coating composition is 1500 to 1800 cP, and when the viscosity is less than 1500 cP, when applied to the surface of the gasket 10, there is a problem that it is not easy to form a coating layer because it flows down, and when it exceeds 1800 cP There is a problem that it is not easy to form a uniform coating layer.

[Preparation Example 1: Preparation of coating layer]

1. Preparation of coating composition

A coating composition was prepared by mixing methyl ethyl ketone with a siloxane-based compound represented by Formula 1, zinc, and trimethylamine:

[Formula 1]

Here, n is an integer from 1 to 100.

A more specific composition of the coating composition is shown in Table 1 below.

TX1 TX2 TX3 TX4 TX5 organic solvent 100 100 100 100 100 polysiloxane 30 40 50 60 70 metal compound 10 20 30 40 50 amine compounds One 5 10 15 20

(unit weight parts)

2. Preparation of coating layer

Typically, an experiment was conducted using aluminum, which is a metal material that is easily corroded, instead of the gasket 10 .

After coating the coating composition of DX1 to DX5 on one surface of 10 × 10 cm aluminum, it was cured to form a coating layer.

Experimental example

1. Evaluation of surface appearance

Due to the difference in viscosity of the coating composition, after preparing the coating layer, a sensory evaluation was conducted on whether a uniform surface was formed. Evaluation was conducted on whether or not a uniform coating layer was formed, and the evaluation was conducted according to the following criteria.

○: uniform coating layer formation

×: Formation of non-uniform coating layer

TX1 TX2 TX3 TX4 TX5 sensory evaluation × ○ ○ ○ ×

When the coating layer is formed, flow occurs on the surface of the gasket 10 when the viscosity is less than a certain level, and it is difficult to form a uniform coating layer after the curing process in many cases. Accordingly, a problem of lowering the production yield may occur. In addition, even when the viscosity is too high, it is difficult to uniformly apply the composition and it is impossible to form a uniform coating layer.

2. Measurement of corrosion properties

In order to confirm the corrosion characteristics, a corrosion resistance test was conducted using an aluminum plate without a coating layer as a control and an aluminum plate with a coating layer of TX1 to TX5.

The aluminum plate was immersed in a beaker containing 10% by weight of CuCl2 aqueous solution, and the degree of corrosion was checked over time.

If the generation of hydrogen gas is visually confirmed, it will be said to mean that corrosion occurs, and it was confirmed whether or not corrosion occurred until 24 hours had elapsed.

○: Corrosion occurs

×: no corrosion

TX1 TX2 TX3 TX4 TX5 control group corrosion occurs ○ × × × × ○

As a result of the experiment, it was confirmed that hydrogen gas was generated shortly after the aluminum plate, which was a control group, was placed in a beaker, and copper was precipitated in less than 1 hour. In the case of TX1, hydrogen gas was generated after 3 hours, and copper precipitation was confirmed after 6 hours.

In the case of other coating layers, corrosion did not occur even after 24 hours, and it was confirmed that there was an excellent effect in preventing corrosion.

Although the coating layer may be coated on the gasket 10 and used, it is preferable that the same coating be used on the surface of the frame part 110 that is exposed to the outside, stores the washing water, and flows the washing water inside.
