본발명은 플라스틱 재질 플랜지 제조방법에 관한 것으로, 플라스틱 재질의 봉을 cnc를 사용하여 절삭하여 플랜지 형상으로 가공하는 단계;를 포함하는 것을 특징으로 한다.The present invention relates to a method of manufacturing a plastic material flange, and a method of cutting a plastic rod using cnc to form a flange shape.

또한, 상기 플라스틱 재질은 pe 인 것을 특징으로 한다.Further, the plastic material is a pe.

또한, 상기 절삭가공된 플랜지 표면위에 에나멜코팅을 하는 단계;를 더포함하는 것을 특징으로 한다.Further, the method further includes the step of applying an enamel coating on the surface of the cut flange.

본발명을 첨부도면에 의해 상세히 설명하면 다음과 같다. 도 1은 본발명의 제조공정에 의해 제조된 플라스틱 재질 플랜지 사진, 도 2는 본발명의 바리제거기 단면도, 도 3은 본발명의 바리제거기 다른 실시예 평면도이다.The present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a photograph of a plastic material flange manufactured by the manufacturing process of the present invention, FIG. 2 is a cross-sectional view of the present invention, and FIG. 3 is a plan view of another embodiment of the present invention.

상기 플랜지는 도넛모양으로서, 원판형 몸체의 중앙에 둥근 결합구멍이 형성되어 축에 삽입될 수 있게 되어 있다. 그리고 몸체의 외주면에는 방사상으로 볼트를 체결할 수 있는 구멍이 다수개 형성되어 있다.The flange is in the form of a donut, and a round coupling hole is formed at the center of the disk-shaped body so as to be inserted into the shaft. A plurality of holes for fastening the bolts radially are formed on the outer peripheral surface of the body.

본발명은 적정길이로 절단한 후 cnc를 사용하여 절삭하여 필요한 수치로 가공하게 된다.In the present invention, after cutting to an appropriate length, it is cut by using cnc and processed to a required value.

그리고 상기 플라스틱 재질은 주로 pe 재질을 사용한다.The plastic material mainly uses a pe material.

한편, 본발명은 절삭후 바리(찌꺼기), 특히 중앙구멍 내벽의 바리를 제거해야 하는데 전용 바리제거기를 사용한다.On the other hand, the present invention uses a special bari remover to remove barriers after cutting, especially barriers on the inner wall of the central hole.

바리제거기는 플랜지에 맞게 원판형의 상부날부와 하부다이로 이루어지며 상부날부는 플랜지 중앙구멍을 관통하면서 내벽의 가운데 둥근절삭날이 하부로 돌출형성되고 주위는 볼트구멍에 삽입되게 다수개의 삽입부가 하부로 돌출 형성된다.The barie eliminator is composed of a disk-shaped upper blade portion and a lower die portion in conformity with the flange. The upper blade portion penetrates the flange center hole while a central round cutting edge of the inner wall protrudes downward and a plurality of insertion portions .

하부다이는 상기 중앙의 둥근절삭날이 삽입되는 중앙홈과, 주위의 삽입부가 삽입되는 삽입홈이 형성된다. 그러므로 플랜지를 상부날부와 하부다이 사이에 안치하고 상부에서 힘을 가하면 플랜지 중앙구멍 내벽의 바리가 제거된다.The lower die has a central groove into which the center round cutting edge is inserted and an insertion groove into which the peripheral insertion portion is inserted. Therefore, when the flange is placed between the upper and lower dies and a force is applied at the upper part, the barriers on the inner wall of the flange center hole are removed.

한편, 중앙구멍이 클 경우 곧 중앙의 둥근절삭날의 지름이 클 경우를 대비하여 상기 중앙의 둥근절삭날은 4개의 절삭편으로 나누어지고 방사상으로 외부방향으로 지름이 확장될 수 있다. 이때 상기 4개의 절삭편을 고정할 수 있게 편에는 고정볼트가 삽입되게 볼트구멍이 형성된다.On the other hand, when the center hole is large, the center round cutting edge is divided into four cutting pieces and the diameter can be radially extended in the outer direction, in case the diameter of the center round cutting edge is large. At this time, a bolt hole is formed in the piece so as to insert the fixing bolt so as to fix the four cutting pieces.

이후 초음파세척에 의해 나머지 바리를 제거한다.Thereafter, the remaining barriers are removed by ultrasonic cleaning.

마지막으로 상기 절삭가공된 플랜지 표면위에 에나멜코팅을 하게 된다.Finally, an enamel coating is applied on the surface of the cut-away flange.

그러므로 본발명은 플랜지 성형후 표면에 쇼트닝 작업이 생략되어도 되어 공정이 간단하고 제조단가가 싼 현저한 효과가 있다.Therefore, the present invention is advantageous in that the shortening operation can be omitted on the surface after the flange molding, and the process is simple and the manufacturing cost is low.
