Description

파이프를 이용한 소형 실린더를 성형하는 열간스피닝 장치Hot spinning device for forming small cylinders using pipes
본 발명은 파이프를 이용한 소형 실린더를 성형하는 열간스피닝 장치에 관한 것으로 보다 상세하게는, SUS316L 소재의 파이프를 이용하여 열간스피닝 장치의 성형수단이 기설정된 이동경로를 따라 비선형적 동작을 수행하여 파이프의 넥부 두께와 파이프 몸체부 두께를 달리 성형할 수 있도록 하는 스피닝 장치에 관한 것이다.The present invention relates to a hot spinning device for forming a small cylinder using a pipe, and more particularly, by using a pipe made of SUS316L, the forming means of the hot spinning device performs a nonlinear operation along a preset movement path. It relates to a spinning apparatus capable of forming different thicknesses of the neck portion and the thickness of the pipe body portion.
스피닝 가공은 롤러(들)에 의해 가해지는 성형 응력을 여러 번 받게 함으로써 부품을 성형하는 제조 공정이다.Spinning is a manufacturing process in which a part is molded by subjecting it to a molding stress exerted by the roller(s) several times.
각각의 금속 요소를 매우 짧은 시간 동안 그 재료의 소성 변형 영역에 이르게 하여 성형한다. 이 공정은 필요한 만큼 여러 번 반복된다. 부품을 거의 무한 번 성형할 수 있는 능력은 프레스 성형 가공과 같은 다른 공정에 비해 상당한 이점을 스피닝 가공에 부여한다. 몇몇 부품은 실제로 기술적 및 상업적으로 허용될 수 있도록 하기 위해 스피닝 가공 공정에 의해서만 제조될 수 있다.Each metallic element is formed by bringing it to the plastically deformed region of the material for a very short period of time. This process is repeated as many times as necessary. The ability to mold parts almost infinitely gives spinning operations a significant advantage over other processes such as press forming operations. Some parts can only be manufactured by means of a spinning process in order to be technically and commercially acceptable in practice.
철강 재료, 알루미늄 합금, 순수 티타늄 등의 판재를 소정의 회전축 주위로 회전시키면서 해당 판재에 가공 도구를 접촉시킴으로써 해당 판재를 가공하여 성형하는 스피닝 성형 방법이 알려져 있다.A spinning molding method is known in which a plate material, such as a steel material, an aluminum alloy, or pure titanium, is rotated around a predetermined rotation axis and a processing tool is brought into contact with the plate material to process and form the plate material.
스피닝 성형 방법은 프레스성형에 비해 복잡한 제품도 쉽게 가공이 가능하고, 두께 조정이 가능하여 전후 공정의 생략, 단축이 가능하며, 회전가공이므로 다른 소성가공과 비교하여 진원도가 뛰어나고 가공칩이 발생하지 않으므로 재료효율 개선에 매우 효과적이라는 장점이 있다.Compared to press molding, the spinning molding method makes it possible to process more complex products more easily, and because the thickness can be adjusted, it is possible to omit or shorten the process before and after, and because it is rotational, it has excellent roundness compared to other plastic machining and does not generate machining chips. It has the advantage of being very effective in improving material efficiency.
종래의 스피닝공정을 이용항 내압실린더 제조방법은 라운드성형과 압출성형 2단계로 이루어지고 스피닝 성형을 수행하는 스피닝 롤러가 일면과 타면의 지름이 같은 단면이 직사각형 형태 또는 타원 형태로서 정밀한 가공을 할 수 없다는 문제점이 있었다.Using the conventional spinning process, the pressure-resistant cylinder manufacturing method consists of two steps: round molding and extrusion molding, and the spinning roller performing spinning has a rectangular or elliptical cross section with the same diameter on one side and the other. There was no problem.
또한, 종래에는 넥부를 성형하는데 있어서, 스피닝롤러가 상기와 같은 형상으로 성형함에 따라 면접촉이 이루어지고, 성형된 파이프의 두께가 넥부와 입구부가 동일하게 성형되는 결과가 나타났다.In addition, conventionally, in forming the neck portion, as the spinning roller is formed into the above-described shape, surface contact is achieved, and the result is that the thickness of the formed pipe is the same as the neck portion and the inlet portion.
하지만, 고압 실린더의 경우 넥부에 많은 압력을 받음에 따라, 넥부의 두께를 더 두껍게 성형해야 하는 필요성이 대두되고, 이에 따른 개발이 절실한 실정이다. However, in the case of a high-pressure cylinder, as a lot of pressure is applied to the neck portion, the necessity to mold the neck portion to be thicker has emerged, and development accordingly is urgently needed.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 전방에서 후방으로 갈수록 단면이 더 작게 형성되어 사다리꼴 형상을 가지는 성형수단을 이용하여 정밀성을 향상시킬 수 있는 스피닝공정을 이용한 소형실린더를 제조하되, 넥부의 두께를 몸체부와 달리 더 두껍게 성형하는 동작을 반복 수행함으로써 소형 실린더를 성형할 수 있는 장비를 제공하는데 그 목적이 있다.The present invention was conceived to solve the above problems, and manufactured a small cylinder using a spinning process capable of improving precision by using a forming means having a trapezoidal shape with a smaller cross section from the front to the rear. It is an object of the present invention to provide an equipment capable of forming a small cylinder by repeatedly performing the operation of forming the neck portion to be thicker than the body portion.
상기 목적을 달성하기 위해 본 발명에 따른 SUS316L 소재의 파이프를 성형하여 넥부, 입구부, 몸체부로 이루어지는 소형 실린더를 제작하는 열간스피닝 장치에 있어서, 전방에 상기 파이프가 장착되는 스핀들과 상기 파이프의 전단을 하방에서 국부적으로 가열시키는 가열수단과 일단에 설치된 상기 롤러가 가열된 상기 파이프의 전단을 가압하여 성형하는 성형수단을 포함하여 이루어지되, 상기 성형수단은 기설정된 이동경로에 따라 비선형적 동작을 반복 수행하여 가열된 상기 파이프 전단을 성형하되, 성형된 상기 파이프의 넥부와 입구부의 두께(d1,d1')가 상기 파이프의 몸체부의 두께(d2)보다 두껍게 성형되도록 하는 것을 특징으로 한다.

That is, by processing the pipe 100 using the edge end of the surface of the large diameter surface of the roller 410, the neck portion 110 is formed, and the contact processing surface 411 which is an inclined surface located between the surface of the large diameter and the other surface. ) Can be used to shape the inlet portion 120 of the pipe 100.
한편, 상기 롤러(410)는 별도의 동력장치와 연결되어 있지 않고, 상기 파이프홀더(220)에 삽입되어 회전하는 상기 파이프(100)와 접촉하여 상기 파이프(100)가 회전함에 따라 상기 롤러(410)도 이와 함께 회전하게 된다. On the other hand, the roller 410 is not connected to a separate power unit, but is inserted into the pipe holder 220 and contacts the pipe 100 to rotate, and the roller 410 is rotated as the pipe 100 rotates. ) Also rotates with this.
일예로, 상기 롤러(410)는 고온의 상기 파이프(100)를 직접 가압하여 접촉을 하는 부위이기 때문에 열적변형이 없고, 내열성이 우수한 재질로 구비되는 것이 바람직하며, 고온의 열을 식힐 수 있도록 물공급 노즐(430)을 통해 상기 롤러(410)가 회전하는 동안 상기 롤러(410)의 상기 접촉가몽면(411)에 물이 공급되어 상기 롤러(410)를 냉각할 수 있도록 구비되는 것이 바람직하다.For example, since the roller 410 is a part that directly presses the high-temperature pipe 100 to contact it, it is preferable that there is no thermal deformation, and is preferably provided with a material having excellent heat resistance, and water to cool the high-temperature heat. It is preferable that water is supplied to the contacting surface 411 of the roller 410 while the roller 410 rotates through the supply nozzle 430 to cool the roller 410.
다음으로, 도 4는 본 발명의 바람직한 실시예에 따른 성형수단에 설치된 롤러의 이동경로를 나타낸 그림이며, 도 5는 본 발명의 바람직한 실시예에 따른 성형수단에 설치된 롤러의 제 1이동경로를 나타낸 그림이고, 도 6은 본 발명의 바람직한 실시예에 따른 성형수단에 설치된 롤러의 제 2이동경로를 나타낸 그림이다.Next, Figure 4 is a picture showing the movement path of the roller installed in the forming means according to a preferred embodiment of the present invention, Figure 5 is a first movement path of the roller installed in the forming means according to a preferred embodiment of the present invention. Fig. 6 is a drawing showing a second moving path of a roller installed in a forming means according to a preferred embodiment of the present invention.
도 4내지 도 6에 도시된 바와 같이, 상기 성형수단은(400) 기설정된 상기 이동경로(500)에 따라 비선형적 동작을 수행할 수 있도록 구비될 수 있다.As shown in FIGS. 4 to 6, the shaping means 400 may be provided to perform a non-linear operation according to the preset movement path 500.
일예로, CAD로 설계한 상기 이동경로(500)를 따라 CNC 프로그램의 좌표값 그래프로 변환되고 설비로 송신되어, 좌표값에 따라 상기 성형수단(400)이 상기 이동경로(500)를 따라 이동할 수 있도록 구비되는 것이 바람직하다. As an example, it is converted into a coordinate value graph of a CNC program along the movement path 500 designed in CAD and transmitted to the facility, so that the molding means 400 can move along the movement path 500 according to the coordinate value. It is desirable to be provided so that.
또한, 상기 성형수단(400)이 이동할 수 있도록 동력을 제공하는 이동용모터(440)가 상기 성형수단(400)의 일단에 부착될 수 있다. In addition, a moving motor 440 that provides power to move the molding means 400 may be attached to one end of the molding means 400.
상기 이동용모터(440)에 의해 구동되는 상기 성형수단(400)은 상기 제 1, 2레일(450, 451)위에서 기설정된 상기 이동경로(500)를 따라 비선형적 동작을 반복 수행하여 가열된 상기 파이프(100) 전단을 성형하되, 성형된 상기 파이프(100)의 상기 넥부(110)와 상기 입구부(120)의 두께(d1,d1')가 상기 파이프(100)의 상기 몸체부(130)의 두께(d2)보다 두껍게 성형될 수 있도록 할 수 있다. The forming means 400 driven by the moving motor 440 repeatedly performs a non-linear operation along the preset moving path 500 on the first and second rails 450 and 451, thereby heating the pipe (100) The front end is formed, but the thickness (d1, d1') of the neck portion 110 and the inlet portion 120 of the formed pipe 100 is It can be formed to be thicker than the thickness d2.
즉, 상기 이동경로(500)는 상기 성형수단(400)이 상기 파이프(100)의 전단을 막힌 곡면 형상으로 성형하여 상기 넥부(110)를 형성시키는 제 1이동경로(510)와, 상기 넥부(110)가 형성된 이후에 상기 곡면 중심부가 전방으로 돌출되어 상기 입구부(120)를 형성시키는 제 2이동경로(520)를 따라 상기 성형수단(400)이 이동하게 된다. That is, the movement path 500 includes a first movement path 510 for forming the neck portion 110 by forming the front end of the pipe 100 into a curved shape by the forming means 400, and the neck portion ( After 110) is formed, the central portion of the curved surface protrudes forward so that the molding means 400 moves along the second movement path 520 forming the inlet portion 120.
한편, 제 1이동경로(510)는, 상기 롤러(410)의 접촉가공면(411)의 끝단이 상기 파이프(100)의 전방 일측 상부에 접촉되어 상기 파이프(100)의 회전과 대응되어 상기 롤러(410)가 회전하는 상태의 위치로 이동하되, 반복되는 성형에 따라 상기 접촉가공면(411)이 단계적으로 소정의 거리만큼 후방으로 이동되어 위치되는 제1시작경로(511)와 상기 제1시작경로(511)를 기준으로 전방 하부를 향하여 비선형적으로 반복 이동을 통한 상기 파이프(100)를 가압하여 상기 파이프(100)의 전단을 전방이 막힌 곡면 형상의 상기 넥부(110)를 형성하는 제1성형경로(512)를 따라 상기 성형수단(400)이 이동하게 된다. On the other hand, in the first movement path 510, the end of the contact processing surface 411 of the roller 410 is in contact with an upper portion of the front one side of the pipe 100 to correspond to the rotation of the pipe 100 so that the roller The first start path 511 and the first start are moved to a position in which 410 is rotated, but the contact processing surface 411 is gradually moved backward by a predetermined distance according to repeated molding. The first which presses the pipe 100 through repeated movement non-linearly toward the front and lower portions based on the path 511 to form the neck portion 110 of the curved shape with the front end of the pipe 100 blocked. The molding means 400 moves along the molding path 512.
이때, 상기 제1성형경로(512)는 반복적인 성형에 따라 상기 파이프(100)의 전방 하부를 향하여 이동하는 경사각이 점차적으로 급하게 형성되는 것을 특징으로 한다.In this case, the first molding path 512 is characterized in that the inclination angle moving toward the front and lower portions of the pipe 100 is gradually and rapidly formed according to repeated molding.
이는, 상기 제 1성형경로(512)에 따라 상기 파이프(100)의 끝단이 반구 형태인 닫힌 상태로 성형하기 위한 과정이며, 반구 형태로 성형이 되어야 상기 넥부(110)가 성형되는 과정에서 내측으로 두께가 증대될 수 있도록 하기 위한 과정이다. This is a process for forming the end of the pipe 100 in a closed state in a hemispherical shape according to the first forming path 512, and the neck portion 110 is formed inwardly in the process of forming the neck portion 110 only when it is formed in a hemispherical shape. This is a process to increase the thickness.
일예로, 상기 제 1시작경로(511)는 상기 접촉가공면(411)으로부터 상기 파이프(100)의 길이 방향을 따라 후방으로 0.1mm 간격으로 이동되도록 좌표값을 설정하여 서로 다른 상기 제 1성형경로(512)를 따라 작업을 수행할 수 있도록 설계할 수 있다. As an example, the first starting path 511 is different from the first molding path by setting a coordinate value to be moved from the contact processing surface 411 to the rear along the length direction of the pipe 100 at 0.1 mm intervals. It can be designed to be able to perform the task according to (512).
또 다른 예로는, 상기 파이프(100)의 전방 일측 상부가 상기 접촉가공면(411)과 접촉하는 압력 및 접촉 시간, 속도 또한 작업자로 하여금 설정할 수 있음은 물론이다. As another example, it goes without saying that the pressure, the contact time, and the speed at which the upper portion of the front side of the pipe 100 contacts the contact processing surface 411 can also be set by the operator.
상기 제 1이동경로(510)를 따라 상기 넥부(110)를 형성한 이후, 상기 성형수단(400)은 상기 입구부(120)을 성형하기 위해 상기 제 2이동경로(520)를 따르게 된다.After forming the neck portion 110 along the first movement path 510, the forming means 400 follows the second movement path 520 to shape the inlet portion 120.
상기 제 2이동경로(520)는, 상기 넥부(110)가 성형된 이후, 상기 롤러(410)의 접촉가공면(411)이 상기 곡면의 시작점 상에 접촉되어 상기 파이프(100)의 회전과 대응되어 상기 롤러(410)가 회전하는 상태의 위치로 이동하되, 반복되는 성형에 따라 상기 접촉가공면(102)이 단계적으로 소정의 거리만큼 후방으로 이동되어 위치되는 제2시작경로(521)와 상기 제2시작경로(521)를 기준으로 전방 하부를 향하여 비선형적으로 반복 이동을 통한 상기 넥부(110)를 가압하여 상기 넥부(110)의 전단 중심부가 전방으로 돌출되어 상기 입구부(120)를 형성시키는 제2성형경로(522)를 포함하여 이루어지되, 상기 제2성형경로(522)의 종착지점(523)에 따라 상기 입구부(120) 외주면의 직경이 결정되도록 설계할 수 있다.The second movement path 520 corresponds to the rotation of the pipe 100 by contacting the contact processing surface 411 of the roller 410 on the starting point of the curved surface after the neck portion 110 is formed. The roller 410 is moved to a position in which the roller 410 rotates, but the contact processing surface 102 is stepwise moved to the rear by a predetermined distance according to repeated molding, and a second start path 521 and the The front-end center of the neck part 110 protrudes forward to form the inlet part 120 by pressing the neck part 110 by repeatedly moving non-linearly toward the front lower part based on the second start path 521 The second molding path 522 is included, and the diameter of the outer circumferential surface of the inlet 120 may be determined according to the end point 523 of the second molding path 522.
다시 말해서, 상기 성형수단(400)은 상기 제 1이동경(510)로를 따라 상기 파이프(100)의 전단을 전방이 막힌 곡면 형상의 상기 넥부(110)를 형성한 이후에 상기 제 2이동경로(520)를 따라 상기 입구부(120)를 성형할 수 있도록 수행되는 것이다.In other words, the forming means 400 forms the neck portion 110 having a curved front end of the pipe 100 along the path of the first moving mirror 510 and then the second moving path ( It is performed so that the inlet portion 120 can be molded along 520.
한편, 상기 제 2성형경로(522)를 따라 상기 종착지점(523)까지 이동하는 반복 성형 작업에 따라 상기 성형수단(400)에 의해 상기 입구부(120)의 길이 및 직경이 결정될 수 있다.Meanwhile, the length and diameter of the inlet part 120 may be determined by the molding means 400 according to the repetitive molding operation moving to the end point 523 along the second molding path 522.
일예로, 상기 파이프(100)의 곡면 형상에 상기 접촉가공면(411)이 접촉하는 압력 및 접촉 시간, 속도 또한 작업자로 하여금 설정할 수 있음은 물론이다. As an example, it goes without saying that the pressure, contact time, and speed that the contact processing surface 411 contacts with the curved shape of the pipe 100 can also be set by the operator.
도 7은 본 발명의 바람직한 실시예에 따른 열간성형공정도를 나타낸 사진이다. 7 is a photograph showing a hot forming process diagram according to a preferred embodiment of the present invention.
도 7에 도시된 사진과 같이, (a)는 상기 파이프(100)가 상기 스핀들(200)과 함께 고속으로 회전하고 있으며, 상기 가열수단(300)에 의해 상기 파이프(100)의 온도를 1200℃까지 상승시키기 위해 상기 가열수단(300)은 지속적으로 열을 공급하게 된다. As shown in the picture shown in Figure 7, (a) is the pipe 100 is rotating at high speed with the spindle 200, the temperature of the pipe 100 by the heating means 300 is 1200 ℃ The heating means 300 continuously supplies heat in order to increase to.
이때, 상기 롤러(410)는 상기 제 1이동경로(510)를 따라 상기 파이프(100)의 전단을 가압함으로써 상기 파이프(100) 끝단이 라운드 되도록 반복되는 성형과정을 수행하게 된다. At this time, the roller 410 presses the front end of the pipe 100 along the first moving path 510 to perform a repeated molding process so that the end of the pipe 100 is rounded.
도 7의 (b)와 같이 상기 롤러(410)의 지속적인 반복작업을 통해 상기 파이프(100)의 끝단은 반구 형태로 변형됨에 따라 최종적으로 닫히게 되고, 소성 상태의 상기 파이프(100)의 상기 몸체부(130)로부터 상기 넥부(110)측으로 밀려온 소재는 상기 넥부(110)의 내측으로 쌓이면서 그 두께를 증대시키게 된다. As shown in (b) of FIG. 7, the end of the pipe 100 is finally closed as the end of the pipe 100 is deformed into a hemispherical shape through the continuous repetitive operation of the roller 410, and the body portion of the pipe 100 in a plastic state The material that has been pushed toward the neck portion 110 from 130 is accumulated in the neck portion 110 to increase its thickness.
도 7의 (c)는 상기 롤러(410)가 상기 제 2이동경로(520)를 따라 상기 넥부(110)를 가압하여 상기 입구부(120)를 형성하는 사진이다.7C is a photograph in which the roller 410 presses the neck portion 110 along the second movement path 520 to form the inlet portion 120.
이때, 상기 넥부(110)의 내측에 적층된 두께의 일부는 상기 입구부(120)로 이동하게 되고, 도 7의 (d)와 같이 상기 성형수단(400)의 순차적인 반복 작업에 따라 상기 파이프(100)의 상기 입구부(120)를 형성할 수 있게 된다.At this time, a part of the thickness stacked on the inside of the neck part 110 moves to the inlet part 120, and the pipe according to the sequential repetitive operation of the forming means 400 as shown in FIG. 7(d). It is possible to form the inlet portion 120 of (100).
일예로, 상기 입구부(120)는 상기 제 2성형경로(522)의 상기 종착지점(523)에 따라 상기 파이프(100)의 상기 입구부(120) 길이를 결정할 수 있음은 물론이다.As an example, the inlet part 120 may determine the length of the inlet part 120 of the pipe 100 according to the end point 523 of the second molding path 522.
다시 말해서, 상기 종착지점(523)을 전방으로 길게 형성하는 경우 상기 입구부(120)의 길이 또한 증대되며, 반대로, 상기 종착지점(523)을 전방으로 짧게 형성하는 경우, 상기 입구부(120)의 길이는 짧아지는 대신, 두껍게 형성할 수 있도록 설계 할 수 있다.In other words, when the end point 523 is formed long in the front, the length of the inlet portion 120 is also increased. Conversely, when the end point 523 is formed short in the forward direction, the inlet portion 120 Instead of shortening the length, it can be designed to be thicker.
