According to the present invention, the marking and cutting process for cutting the marked portion after marking the raw material by dividing the shape 360 degrees circle of the parts forming the eccentric cone into equal parts, and using the bending roller or hydraulic press In the bending and bending process of bending or bending by using, the joining process of welding and joining the bent or bent, and the manufacturing method of an eccentric cone having a knuckle which eccentrically forms the upper and lower parts of the finished product, the knuckle is The manufacturing method of the eccentric cone which includes the product installation step of raising the lower portion of the product on the molding machine rotary table eccentric installation fixed; An upper knuckle eccentric forming process for forming the upper knuckle of the product into an eccentric shape by using an inner outer hydraulic roller; A product installation process of mounting the upper part of the product on an eccentric rotary table and fixing the eccentric installation; A lower knuckle eccentric forming process for forming the product lower knuckle into an eccentric shape using an inner outer hydraulic roller is achieved by the manufacturing method of the knuckle eccentric cone.

이상에서 설명한 바와 같이, 본 발명에 따른 너클이 있는 편심 콘은 상온에서 편심형상으로 성형 함으로써, 물리적 특성의 변화가 없으므로 내압에 의한 응력에 충분하여 제품의 안전성이 보장될 수 있으며 원자재 두께 50mm까지도 작업이 가능하여 제품의 신뢰성을 확보할 수 있음과 아울러 자재절감, 제조비용 절감과 더불어 제조 시간을 대폭 줄일 수 있는 효과가 있다.As described above, the eccentric cone with a knuckle according to the present invention is formed in an eccentric shape at room temperature, so that there is no change in physical properties, so it is sufficient for stress due to internal pressure, and thus the safety of the product can be ensured, and even the raw material thickness up to 50 mm In this way, it is possible to secure the reliability of the product, and to save material, reduce manufacturing costs, and significantly reduce manufacturing time.

이하에서는 첨부된 도면을 참조하여 본 발명에 대하여 상세히 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

도 2 는 본 발명에 따른 너클이 있는 편심 콘의 제조공정을 순차적으로 나타낸 공정도에 관한 것이다.
이들 도면에서 볼 수 있는 바와 같이, 본 발명에 따른 너클이 있는 편심 콘의 제조공법은 너클이 있는 편심 콘(10)의 사용 용도에 따라 원자재(20) 두께 50mm까지 작업이 가능하다.Figure 2 relates to a process diagram sequentially showing the manufacturing process of the eccentric cone with knuckles according to the present invention.
As can be seen in these figures, the manufacturing method of the knuckle-based eccentric cone according to the present invention can work up to 50mm in thickness of the raw material 20, depending on the intended use of the knuckle-based eccentric cone 10.

너클이 있는 편심 콘(10)을 형성하기 위하여 원자재(20)에 부품(30)의 형상 360도 원형을 등분하여 마킹한 후 마킹된 부분을 절단하는 마킹 및 절단공정(S10)을 거친다. 이어서 절단된 각 부품(30)을 벤딩롤러 또는 유압프레스(도시치 않음)로 벤딩 또는 절곡하는 벤딩 및 절곡공정(S20)을 거친다In order to form the eccentric cone 10 with knuckles, the raw material 20 is marked by dividing the shape 360 degrees of the part 30 into equal parts and then undergoes the marking and cutting process S10 of cutting the marked portion. Subsequently, each cut part 30 is subjected to a bending and bending process (S20) of bending or bending the bending roller or a hydraulic press (not shown).

그리고 벤딩 또는 절곡된 부품(30)의 양측 단부를 이음 용접하는 것으로서 콘 형상으로 형성하는 접합공정(S30)을 거친다.
이후 콘 형상으로 형성된 제품(40)의 하부를 성형기 회전테이블(70)에 편심 설치 고정하는 제품설치공정(S40)을 거친 후, 내 외측 유압롤러(50)(60)를 사용하여 상부 너클을 편심형상으로 성형하는 편심성형공정(S40)을 거친다.
이때 작업자가 제품(40)에 열을 가할 때 원재료의 물리적 특성을 감안하여 두께가 얇은 원자재는 상온에서 형상을 성형하고, 두께가 두꺼운 원자재는 프로판가스로 토치가열 또는 전기가열을 통해 제품(40)을 가열함과 아울러 제품을 서서히 회전시키면서 형상 성형함으로써 제품(40)의 형상 성형작업을 쉽게 할 수 있다.Then, both ends of the bent or bent part 30 are welded to each other, and the bonding process S30 is formed in a cone shape.
After going through the product installation process (S40) to eccentrically install and fix the lower portion of the product 40 formed in the cone shape to the molding machine rotation table 70, the upper knuckle is eccentric using the inner and outer hydraulic rollers 50, 60 It goes through an eccentric molding step (S40) for molding into a shape.
At this time, when the worker applies heat to the product 40, the thin raw material is shaped at room temperature in consideration of the physical characteristics of the raw material, and the thick raw material is produced by torch heating or electric heating with propane gas. The shape molding operation of the product 40 can be easily performed by heating the product and shape molding the product while gradually rotating the product.

이어서 하부 너클 편심형상 성형을 하기 위해 제품(40)의 상부를 성형기 회전테이블(70)에 편심 설치 고정하는 제품설치공정(S50)을 거친 후, 내 외측 유압롤러(60)(50)를 사용하여 하부 너클을 편심형상으로 성형하는 공정(S50)을 거치는데 이때 작업자가 제품(40)에 열을 가할 때 원재료의 물리적 특성을 감안하여 두께가 얇은 원자재는 상온에서 형상성형하고 두께가 두꺼운 원자재는 프로판가스로 토치가열 또는 전기가열을 통해 제품(40)을 가열함과 아울러 제품을 서서히 회전시키면서 형상 성형함으로써 제품(40)의 형상 성형 작업을 쉽게 할 수 있다. Subsequently, in order to form the lower knuckle eccentric shape after the product installation process (S50) to eccentrically install and fix the upper part of the product 40 to the molding machine rotary table 70, using the inner and outer hydraulic rollers (60) and (50) The lower knuckle is formed into an eccentric shape (S50). In this case, when the worker heats the product 40, the raw material is formed at room temperature in consideration of the physical characteristics of the raw material, and the raw material is made of propane. The shape-molding operation of the product 40 can be easily performed by heating the product 40 through torch heating or electric heating with gas, and by shape-molding the product while slowly rotating the product.

이상에서와 같은 제조공법에 의해서 도 3에서와 같은 너클이 있는 편심 콘을 제조할 수 있기 때문에 종래와 달리 금형을 매번 제작하지 않으므로 경제성이 있으며, 자재 절감, 제조비용 절감과 더불어 제조 시간을 대폭 줄일 수 있다.Since it is possible to manufacture the eccentric cone with knuckles as shown in Figure 3 by the manufacturing method as described above, it is economical because the mold is not produced every time unlike the prior art, and the material time, manufacturing cost reduction and manufacturing time are greatly reduced. Can be.
