Description
본 발명은 환편기에 관한 것으로, 보다 상세하게는 환편기의 편성부의 구성부품 및 그 제조방법에 관한 것이다.The present invention relates to a circular knitting machine, and more particularly, to a component part of the knitting portion of the circular knitting machine and a manufacturing method thereof.
환편기는 급사장치와, 실린더 및 바늘로 이루어지는 편성부와, 상기 편성부에서 편직물된 사를 감아서 정리하는 정리부로 대략 구성된다.The circular knitting machine is roughly composed of a feeding device, a knitting portion consisting of a cylinder and a needle, and a finishing portion for winding up and knitting the yarn knitted in the knitting portion.
편성부는 도 1에 도시한 바와 같이, 통상적으로 상, 하 두 개의 실린더를 구비하고 있다. 상부실린더는 다이얼(4)이라고도 불리우므로 여기서는 다이얼이라 한다. 실린더(1)와 다이얼(4)은 직각방향으로 만나고 있으며, 실린더(1)의 외부둘레에는 원형으로 나란히 줄선 축선방향으로 뻗친 다수의 침홈(1a)이 형성되어 있으며, 각 침홈에는 수직방향으로 이동이 자유로운 실린더 침(2)이 수용되어 있다. 실린더 침(2)은 작동용 배트(batt)(2a)를 지니고 있다.As shown in Fig. 1, the knitting portion is usually provided with two cylinders, upper and lower. The upper cylinder is also referred to as dial 4 here, so it is called dial. The cylinder 1 and the dial 4 meet at right angles, and the outer periphery of the cylinder 1 is formed with a plurality of needle grooves 1a extending in the axial direction in parallel with each other, and each needle groove moves in the vertical direction. This free cylinder needle 2 is accommodated. The cylinder needle 2 has an operating bat 2a.
한편, 실린더(1)와 같이 회전하는 다이얼(4)에는 실린더침(2)과 협조하여 사를 편직하는 다이얼침(3)이 상기 실린더 침(2)과 동일한 방식으로 위치하고 있고, 수평방향으로 다이얼(4)에 반지름방향으로 슬립가능하도록 배치되어 있다.On the other hand, in the dial 4 which rotates like the cylinder 1, the dial needle 3 which knits the yarn in cooperation with the cylinder needle 2 is located in the same manner as the cylinder needle 2, and the dial is horizontally It is arrange | positioned so that it can slip in radial direction at (4).
위 실린더(1)는 구동치차(6)에 의해 고정되어 있고, 다이얼(4)은 다이얼허브(7)에 연결되어 통상 동일한 속도로 회전하고 있다.The upper cylinder 1 is fixed by the drive gear 6, and the dial 4 is connected to the dial hub 7 and is usually rotating at the same speed.
실린더침(2)은 실린더캠홀더(8)에 설치된 적어도 하나의 제어캠(9)에 의해 작동되고, 다이얼침(3)은 다이얼캠허브(13)에 설치된 다이얼캠홀더(11)에 의해 작동 및 제어된다.The cylinder needle 2 is operated by at least one control cam 9 installed in the cylinder cam holder 8, and the dial needle 3 is operated by the dial cam holder 11 installed in the dial cam hub 13. And controlled.
본 발명은 상기와 같이 구성된 환편기의 편성부에 관한 것으로, 통상적으로 다이얼 및 실린더는 탄소함량이 아주 적은 연질의 캐석강을 사용하고 있다. 이는 실런더 침 및 다이얼 침을 위한 침홈을 형성할 때, 커터(cutter)에 의한 절삭작업을 용이하게 하기 위함이다.The present invention relates to a knitting portion of a circular knitting machine configured as described above. In general, the dial and the cylinder use a soft catapult steel having a very low carbon content. This is to facilitate the cutting operation by the cutter when forming the needle grooves for the cylinder needle and the dial needle.
그런데, 이 캐석강은 너무 연질이므로 도 1에 도시한 바와 같이, 실린더침과 다이얼침에 의해 편직될 때 각 침과 실린더 및 다이얼의 끝단이 사(絲)와 스치게되면, 마모가 발생하게 되고 이는 역으로 사에 안좋은 영향을 미쳐 실이 피는 현상이발생하게 된다.By the way, since this cavern steel is so soft, as shown in FIG. 1, when knitting by the cylinder needle and a dial needle, when the tip of each needle, a cylinder, and a dial rub against a yarn, abrasion will arise. This in turn adversely affects the yarn, which causes threading to occur.
이에 종래기술에서는 실린더 및 다이얼의 끝단부위에 고주파열처리를 하여 경도를 향상시키고 있다.In the prior art, high-frequency heat treatment is applied to the end portions of the cylinder and the dial to improve hardness.
그러나, 이 경우에도 경도는 50내외로서 화학사에 의한 마모율이 높고, 또한 고주파 열처리시 실린더가 비틀려지는 문제가 있다. 뿐만아니라, 실런더의 표면이 매끄럽지 못하여 실에 의한 실린더의 손상이나 역으로 실린더에 의한 실의 손상이 발생하게 되는 문제점이 있다.However, even in this case, the hardness is about 50, the wear rate by the chemical company is high, and there is a problem that the cylinder is twisted during high frequency heat treatment. In addition, there is a problem in that the surface of the cylinder is not smooth and damage of the cylinder by the seal or, conversely, damage of the seal by the cylinder occurs.
이는 SK-5로 제조하는 침의 경우에도 동일하게 적용된다.The same applies to the case of saliva made with SK-5.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 상기와 같은 환편기에서 실과의 접촉부위에서 발생하는 마모와 매끄럽지 못한 부분을 해결할 수 있는 편성부 및 그 제조방법을 제공하는 것이다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a knitted portion and a method of manufacturing the same to solve the wear and uneven parts occurring in the contact portion with the yarn in the circular knitting machine as described above. To provide.

상기와 같은 목적을 달성하기 위해 본 발명은 탄소함량이 적은 캐석강에 커터등을 사용한 절삭작업 후 플라즈마연마를 하고, 이후 윤할성 하드코팅을 행한 편성부의 부품을 제공한다.In order to achieve the above object, the present invention provides a part of the knitted portion subjected to plasma polishing after the cutting operation using a cutter or the like on the cationic steel with a low carbon content, and then subjected to lubricating hard coating.
상기 하드코팅은 바람직하게 크롬이나 티타늄을 사용한다.The hard coating preferably uses chromium or titanium.
하드코팅의 방법은 바람직하게 플라즈마스퍼터링법에 의한다.The method of hard coating is preferably by plasma sputtering.
이하 본 발명을 상세히 설명하면, 환편기의 편성부품에 커터 등으로 절삭하여 침홈 등을 형성하고 마무리 공정에 들어간다.Hereinafter, the present invention will be described in detail, the knitting parts of the circular knitting machine are cut with a cutter or the like to form needle grooves or the like and enter a finishing process.
본 발명에서의 마무리공정에는 먼저 실과 만나는 실린더나 다이얼의 끝단, 그리고 각 침(여기서는 통칭하여 사접촉부위라한다.)에 플라즈마 연마를 한다. 플라즈마 연마는 미세연마라고도 하며, 타겟 즉, 피연마부재에 높은 운동에너지를 가진 플라즈마가스를 가하여 표면을 부드럽게 하는 역할을 한다.In the finishing step of the present invention, plasma polishing is first performed on the end of the cylinder or dial that meets the thread, and on each needle (commonly referred to as a four-contacting part). Plasma polishing is also called fine polishing, and serves to soften the surface by applying plasma gas having a high kinetic energy to the target, that is, the member to be polished.
이때 가해지는 플라즈마가스는 통상 불활성기체인 헬륨, 수소, 질소 등을 플라즈마화하여 스퍼터링하게 되면, 표면이 미세구조에서도 평탄화되어 부드러운 표면을 달성할 수 있다. 이런 플라즈마연마의 방법으로는 마그네틱스퍼터링 등이 있다.At this time, when the plasma gas is sputtered by plasma-forming helium, hydrogen, nitrogen, and the like, which is usually inert gas, the surface may be flattened even in a microstructure to achieve a smooth surface. Such methods of plasma polishing include magnetic sputtering.
다음 단계로서 상기 미세연마된 사접촉부위에 박막을 성장하는 물리기상증착(physical vapor deposition ; PVD)을 사용한다.As a next step, physical vapor deposition (PVD) is used, in which a thin film is grown on the finely ground four contact portions.
이 방법은 하드코팅이라고도 불리우며, 코팅, 즉 성막하고자 하는 재질을 타켓으로 하여 적절한 플라즈마가스를 가하면 상기 타겟의 이온이 튀어나와 원하는 부재에 코팅되는 방법이다.This method, also called hard coating, is a method of coating, i.e., applying a suitable plasma gas to target a material to be deposited, and the ion of the target is popped out and coated on a desired member.
상세히 설명하면, 타겟 표면에 자기장이 형성되면, 음극의 타겟 표면으로부터 플라즈마 방전된 입자가 상기 타겟 표면으로 가속되고, 가속된 이온에 의해 타겟표면이 스퍼터되면서, 상기 스퍼터된 타겟의 원자가 시편표면(여기서는 사접촉부위)에 증착되게 된다.In detail, when a magnetic field is formed on the target surface, plasma-discharged particles are accelerated from the target surface of the cathode to the target surface, and the target surface is sputtered by the accelerated ions, whereby the valence specimen surface of the sputtered target (here Four-contact part).
본 발명에서 적용하는 타겟은 티타늄(Ti), 또는 크롬(Cr)이며, 불활성플라즈마로서 질소(N2)를 사용하면, 사접촉부위에는 티타늄나이트라이트(TiN) 또는 크롬나이트라이트(CrN)가 코팅되게 된다.The target to be applied in the present invention is titanium (Ti) or chromium (Cr), and when nitrogen (N2) is used as the inert plasma, the titanium contacts are coated with titanium nitride (TiN) or chromium nitride (CrN). do.
상기 설명한 바와 같이, 본 발명에 따라 사접촉부위 즉, 실린더 및 다이얼의 끝단과 각 침에 플라즈마연마 및 윤할성하드코팅을 실시한 결과 경도는 약 80 정도로 향상됨으로써 마모를 배제할 수 있으므로 부품의 수명이 연장되는 효과를 얻었다.As described above, according to the present invention, as a result of performing plasma polishing and lubricating hard coating on the four contact portions, that is, the ends of the cylinders and dials, and the needles, the hardness is improved to about 80, so that wear can be eliminated, so that the life of the parts is increased. Prolonged effect was obtained.
또한 플라즈마연마로 인하여 표면이 부드러워지므로 실손상이 방지되는 효과가 발생하였다.In addition, since the surface is softened by plasma polishing, an effect of preventing thread damage occurs.
상기 설명한 바와 같이, 본 발명에 따라 제조된 환편기의 편성부로 인하여 제조된 직물에 불연속적으로 발생하던 핌을 방지할 수 있고, 제조기기의 수명을 연장할 수 있는 이점이 있다.As described above, due to the knitting portion of the circular knitting machine manufactured according to the present invention, there is an advantage in that it is possible to prevent discontinuity in the fabric produced and to extend the life of the manufacturing apparatus.
