이러한 플랜지는 관의 직경이 작은 경우 프레스가공과 같은 손쉬운 작업에 의해 가공이 가능하였으나 관의 직경이 클 경우는 플랜지의 가공하기 불가능한 실정이었다.Such a flange can be processed by an easy operation such as press working when the diameter of the tube is small, but it is impossible to process the flange when the diameter of the tube is large.
따라서, 관의 직경이 클 경우 플랜지부를 따로 만드는 공정과 모재와 용접하는 공정 그리고 마무리 작업까지 여러공정과 많은 시간이 소요되어 왔었다.Therefore, when the diameter of the pipe is large, the process of making the flange part separately, the process of welding with the base metal, and the finishing work have been required for many processes and a lot of time.
또한 상기와 같은 공정은 사람의 손이 많이 가기 때문에 자동화하기에 어려운 실정이었다.In addition, the process as described above was difficult to automate because many hands go.
본 발명은 상기와 같은 문제점들을 해소하기 위한 것으로 작업공정을 단순화하여 관과 일체로 플랜지를 제작할 수 있는 플랜지 성형방법 및 플랜지 성형장치를 제공하는데 목적이 있다. 상기와 같은 목적을 달성하기 위한 본 발명의 특징으로는 드럼형의 모재를 중심축을 기준으로 회전되도록 지지하고, 상기 모재의 일측외경에 접하도록 위치한 회전롤러의 회전을 통해 모재를 회전시키고, 상기 회전롤러와 대응하는 모재의 내경에 위치하여 이 회전롤러의 방향으로 모재의 축방향과 소정각도로 가압하여 모제의 일단을 신장밴딩하는 플랜지 성형방법이다.The present invention has been made to solve the above problems and to provide a flange forming method and a flange forming apparatus that can simplify the work process to produce a flange integrally with the pipe. Features of the present invention for achieving the above object is to support the drum-shaped base material to be rotated relative to the central axis, and to rotate the base material through the rotation of the rotary roller positioned to contact one side outer diameter of the base material, the rotation It is a flange molding method which is located in the inner diameter of a base material corresponding to a roller and pressurizes one end of a base material by pressurizing it at the predetermined direction and the axial direction of a base material in the direction of this rotating roller.
본 발명의 또다른 특징으로는 가공선반의 상부면 양측에 모재의 외주면을 지지하는 고정가이드롤러와 이 선반의 양단에 전후좌우 이동되어 모재의 내경을 지지하는 이송가이드롤러를 구비한 고정지지부와, 상기 선반에 고정된 모재의 외경 일측단에 접하여 동력부에 의해 회전하는 회전롤러와, 상기 회전롤러측 선반의 상부에 고정되되 각각의 유압실린더에 의해 상하좌우 이동하는 가압롤러를 포함하는 플랜지 성형장치이다. 본 발명을 첨부된 도면에 의하여 상세히 기술하면 다음과 같다.Another feature of the present invention is a fixed support roller having a fixed guide roller for supporting the outer circumferential surface of the base material on both sides of the upper surface of the working lathe and a transfer guide roller which is moved back and forth and left and right at both ends of the shelf to support the inner diameter of the base material, Flange forming apparatus including a rotary roller which is rotated by the power unit in contact with one end of the outer diameter of the base material fixed to the shelf, and a pressure roller fixed to the upper portion of the rotary roller side shelf and moved up, down, left and right by respective hydraulic cylinders. to be. The present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 발명의 전체적인 구성을 나타낸 사시도이다. 가공선반(10)의 양측에는 고정롤러(20)가 드럼형의 모재(100)의 외경을 지지하고 이 선반(10)의 일측에는 수평, 회전위치의 이송가이드롤러(30)에 의해 이 모재의 길이 방향의 양측에서 이모재(100)의 내경에 밀착하여 가공시 이모재(100)의 이탈을 방지하고 회전가능하도록 지지한다.1 is a perspective view showing the overall configuration of the present invention. On both sides of the working lathe 10, fixed rollers 20 support the outer diameter of the drum-shaped base material 100, and on one side of the lathe 10, the feed guide rollers 30 of horizontal and rotational positions of the base material In close contact with the inner diameter of the emoji material 100 on both sides in the longitudinal direction to prevent the separation of the emoji 100 during processing and to support the rotatable.
구동롤로(40)는 상기 가공선반(10)보다 상대적으로 높게 위치하여 상기 드럼형의 모재 (100)의 외주면의 지면에 밀착되어 회전한다. 상기 구동롤러(40)를 동작시키는 동력부(60)로는 모터와 감속기를 사용하거나, 동력차단효과가 좋은 유압모터로 사용할 수 있다. 상기 모재(100)를 성형시키는 가압롤러(50)는 전후 동작하는 유압실린더(70)와 상하 동작하는 유압실린더(80)에 의해 모재(100)의 내경에 위치하게 된다. 또한 작업선반(10)의 길이는 모재의 길이에 따라 조절핸들(13)에 의해 이송레일(15)을 통해 조절된다.The drive roller 40 is positioned relatively higher than the working lathe 10 and rotates in close contact with the ground of the outer circumferential surface of the drum-shaped base material 100. As the power unit 60 for operating the drive roller 40, a motor and a speed reducer may be used, or a hydraulic motor having a good power cutoff effect may be used. The pressure roller 50 for molding the base material 100 is positioned at the inner diameter of the base material 100 by the hydraulic cylinder 70 that operates back and forth and the hydraulic cylinder 80 which operates up and down. In addition, the length of the working shelf 10 is adjusted through the conveyance rail 15 by the adjusting handle 13 according to the length of the base material.
제2a,b도는 본 발명의 성형가공의 실시예를 개략적으로 나타낸 것이다. 동작방법을 보면 먼저 상기 가공선반(10) 상부 상기 고정가이드롤러(20)위에 원통형의 모래(100)를 안착시킨 후 상기 이송가이드롤러(30)의 직선회전운동으로 상기 모재(100)의 내경에서 이 고정가이드롤러(20)와 이모재(100)사이를 밀착고정시킨다. 구동롤러(40)는 상기 모재(100)이 밑면의 외경에 밀착회전하여 이 모재를 원주상에 접하여 회전시키고 상기 가압롤로(50)는 이 모재(100)이 내경에서 이 구동롤러(40)와 소정의 간격을 두고 상부에 위치하도록 이동시킨다.Figure 2a, b schematically shows an embodiment of the molding process of the present invention. In the operating method, first, the cylindrical sand 100 is seated on the fixed guide roller 20 on the upper part of the processing lathe 10, and then in the inner diameter of the base material 100 by a linear rotational movement of the feed guide roller 30. The fixed guide roller 20 and the emoji material 100 is tightly fixed. The driving roller 40 rotates the base material 100 in close contact with the outer diameter of the bottom surface and rotates the base material in contact with the circumference, and the pressure roller 50 has the base material 100 with the drive roller 40 at the inner diameter. It is moved so as to be located at an upper portion with a predetermined interval.
이때 상기 가동롤러(50)가 상기 모재(100)의 길이방향과 수직으로 동작하여 이 모재(100)를 가압하며 회전하면서 이 모재의 일측을 신장굴절시켜 플랜지를 생성시킨다. 상기 가압롤러(50)의 동작속도는 상기 모재(100) 재질에 따른 연신율이나 두께 그리고 상기 구동롤러(40)의 회전속도에 따라 정해지게 된다. 플랜지(100a)의 성형이 끝난후에는 작업공정의 반대로 동작시켜 모재의 타측단을 가공하거나, 작업선반(10)으로 부터 이 모재(100)를 분리시킬 수 있다.At this time, the movable roller 50 is operated perpendicular to the longitudinal direction of the base material 100 to press and rotate the base material 100 while extending and bend one side of the base material to create a flange. The operating speed of the pressure roller 50 is determined according to the elongation or thickness according to the base material 100 and the rotational speed of the drive roller 40. After the forming of the flange 100a is completed, the other side of the base material may be processed by operating the reverse of the work process, or the base material 100 may be separated from the work shelf 10.
또한, 상기 모재(100)와 플랜지(100a)의 이루는 각은 상기 구동롤러(40)와 가압롤러(50)의 위치의 변경에 따라 조절가능하다. 상기의 전공정은 상온에서 행해진다. 또한 상기와 같은 공정으로 플랜지가 성형된 관 내부에 팬과 같은 회전체를 넣어 고정하여 축류 송풍기로 사용될 수 있다. 즉, 상기와 같은 작업으로 산업상에 많이 사용되는 직경이 큰 모재의 플랜지 작업시 번거러웠던 여러작업 공정을 자동화할 수 있으므로 제품의 단가를 낮춰 가격 경쟁력을 가질 수 있는 이점이 있다.In addition, the angle formed by the base material 100 and the flange (100a) is adjustable according to the change of the position of the drive roller 40 and the pressure roller (50). The preceding step is performed at room temperature. In addition, by inserting a rotating body such as a fan inside the flange-shaped tube in the above process can be used as an axial flow blower. In other words, it is possible to automate a number of work processes that were cumbersome when flange work of a large diameter base material used in the industry by the above operations, there is an advantage that the price of the product can be lowered to have a competitive price.
