도면을 참조하여 본 발명의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.
도1은 본 발명에 따른 금속세선 제조장치를 나타내는 단면도이고, 도2는 본 발명에 따른 금속세선 제조장치를 나타내는 일측면도이다.1 is a cross-sectional view showing a metal thin wire manufacturing apparatus according to the present invention, Figure 2 is a side view showing a metal thin wire manufacturing apparatus according to the present invention.
주행휠(19)에 의해 이동이 가능하도록 설치되는 대차(20)에는 그 상부에 진공쳄버(4)가 고정 설치되어 있고, 이 진공쳄버(4)는 진공펌프(10)에 의해 그 내압이 진공을 이루면서 내부의 이물질을 제거하게 된다.In the trolley 20 installed to be movable by the traveling wheel 19, a vacuum chamber 4 is fixedly installed on the upper portion thereof, and the vacuum pressure is vacuumed by the vacuum pump 10. To achieve this will remove the foreign matter inside.
이는 도가니(2)내의 금속재료가 용융되는 과정에서 진공쳄버(4)내의 공기, 가스, 기타 이물질과 반응하는 것을 차단함으로써 용융금속(3)이 청정을 유지하도록 하기 위함이다.This is to prevent the molten metal 3 from being kept clean by preventing the metal material in the crucible 2 from reacting with air, gas, and other foreign matter in the vacuum chamber 4 in the process of melting.
그리고, 진공쳄버(4)의 내벽을 따라 설치되는 히터(9)는 진공상태의 진공쳄버(4)의 분위기온도를 용융금속(3)의 용융점에 근접하도록 가열함으로써 회전통(5-1)내의 용융금속(3)이 응고되지 않도록 한다.Then, the heater 9 provided along the inner wall of the vacuum chamber 4 heats the ambient temperature of the vacuum chamber 4 in the vacuum state to approach the melting point of the molten metal 3 in the rotary cylinder 5-1. Do not allow the molten metal (3) to solidify.
이때, 온도측정센서(7)는 진공쳄버(4)의 분위기온도를 측정하게 되고, 이로부터 히터(9)의 작동이 제어된다.At this time, the temperature measuring sensor 7 measures the ambient temperature of the vacuum chamber 4, from which the operation of the heater 9 is controlled.
또한, 진공쳄버(4)의 중앙에 받침대(14)에 의해 지지되도록 내장되는 도가니(2)에는 그 외주면에 유도코일(1)이 감겨져 있고, 이 유도코일에 전원을 인가하게 되면 그 내부에 장입되어 있는 일정량의 철, 비철, 기타 금속재료가 용융되면서 용융금속(3)을 생산하게 된다.In addition, the induction coil 1 is wound around the outer circumferential surface of the crucible 2 embedded in the center of the vacuum chamber 4 so as to be supported by the pedestal 14, and when the power is applied to the induction coil, it is charged therein. A certain amount of ferrous, non-ferrous, and other metal materials are melted to produce molten metal (3).
한편, 도가니(2)의 하부에 위치하도록 진공쳄버(4)에 내장되는 회전통(5)은 모터(11)의 구동축(8) 상단에 체결되어 2,700∼10,000rpm으로 회전이 이루어 지게 된다.On the other hand, the rotary cylinder 5 embedded in the vacuum chamber 4 to be located below the crucible 2 is fastened to the upper end of the drive shaft 8 of the motor 11 is to be rotated at 2,700 ~ 10,000rpm.
이때, 그 외주면을 따라 세선노즐(5-1)이 형성되는 회전통(5)에는 도가니(2)의 용융금속(3)이 담기게 되고, 회전통에 담기는 용융금속에는 회전통의 고속회전에 의해 원심력이 작용된다.At this time, the molten metal 3 of the crucible 2 is contained in the rotary cylinder 5 in which the fine wire nozzle 5-1 is formed along the outer circumferential surface thereof, and the molten metal contained in the rotary cylinder rotates at a high speed. Centrifugal force is applied.
따라서, 회전통(5)내의 용융금속(3)은 회전통의 외측으로 쏠리면서 세선노즐(5-1)을 통해 외부로 배출된다.Accordingly, the molten metal 3 in the rotary cylinder 5 is discharged to the outside through the thin wire nozzle 5-1 while being pulled out of the rotary cylinder.
여기서, 회전통(5)의 외주면을 따라 약 2∼3mm 상부에 위치하도록 설치되는 가스분사링(15)에서는 전자변(6)에 의해 개폐되는 가스공급라인(16)으로부터 불활성가스를 공급받아 세선노즐(5-1)을 통해 배출되는 금속세선(13)에 분사하게 된다.Here, in the gas injection ring 15 installed to be positioned about 2 to 3 mm above the outer circumferential surface of the rotating cylinder 5, the inert gas is supplied from the gas supply line 16 that is opened and closed by the electromagnetic valve 6. Sprayed to the fine metal wire 13 discharged through (5-1).
이때, 가스분사링(15)을 통해 분사되는 불활성가스는 금속세선(13)을 냉각시킬 뿐만아니라 산화를 방지하게 된다.At this time, the inert gas injected through the gas injection ring 15 not only cools the metal fine wire 13 but also prevents oxidation.
한편, 세선노즐(5-1)을 통해 배출되는 금속세선(13)은 진공쳄버(4)의 하부측에 쌓이게 되고, 일정량이 쌓이면 외부로 수거하여 제품화하게 된다.On the other hand, the fine metal wire 13 discharged through the fine wire nozzle (5-1) is accumulated on the lower side of the vacuum chamber 4, when a predetermined amount is accumulated to the outside to collect the product.
그리고, 진공쳄버(4)의 일측에 설치되는 투시창(12)은 진공쳄버의 작업상태를 작업자가 수시로 확인할 수 있도록 하기 위해 설치된다.Then, the see-through window 12 installed on one side of the vacuum chamber 4 is installed to allow the operator to check the working state of the vacuum chamber at any time.
이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.
진공쳄버(4)내의 도가니(2)에 일정량의 철, 비철, 기타 금속재료를 장입하고, 진공펌프(10)를 작동시켜 진공쳄버(4)내의 압력을 10-2∼10-3Torr까지 낮춘 다음, 다시 진공쳄버내의 공기, 가스, 기타 이물질을 제거한 상태에서 진공쳄버의 내압을 10-1Torr로 유지시키게 된다.A certain amount of ferrous, non-ferrous and other metal materials are charged into the crucible 2 in the vacuum chamber 4, and the vacuum pump 10 is operated to lower the pressure in the vacuum chamber 4 to 10 -2 to 10 -3 Torr. Next, the internal pressure of the vacuum chamber is maintained at 10 −1 Torr while air, gas, and other foreign matter in the vacuum chamber are removed again.
그리고, 히터(9)를 작동시켜 진공쳄버(4)내의 온도를 도가니(2)에 내장된 금속의 용융점에 준하는 온도이상으로 가열시키게 되고, 이는 회전통(5)내의 용융금속이 응고되지 않고 노즐구멍(5-1)으로 계속 배출되도록 하기 위함이다.Then, the heater 9 is operated to heat the temperature in the vacuum chamber 4 above the temperature corresponding to the melting point of the metal embedded in the crucible 2, which causes the molten metal in the rotary cylinder 5 to not solidify. This is to continue to discharge through the hole (5-1).
이때, 온도측정센서(7)를 통해 진공쳄버(4)내의 분위기온도를 검출하여 히터(9)의 작동을 제어하게 된다.At this time, the operation of the heater 9 is controlled by detecting the ambient temperature in the vacuum chamber 4 through the temperature measuring sensor 7.
또한, 유도코일(1)에 전류를 인가하여 도가니(2)를 1300∼2500℃까지 가열하게 되면 도가니내의 금속재료가 용융금속(3)으로 용융되고, 이 용융금속은 하부연결관을 통해 회전통(5)으로 공급된다.In addition, when a current is applied to the induction coil 1 and the crucible 2 is heated to 1300 to 2500 ° C., the metal material in the crucible is melted into the molten metal 3, and the molten metal is rotated through the lower connection pipe. It is supplied to (5).
여기서, 모터(11)의 작동으로 구동축(8)에 연결된 회전통(5)이 2,700∼10,000rpm으로 회전되면 회전통내의 용융금속(3)은 회전통의 원심력에 의해 외측으로 쏠리면서 세선노즐(5-1)을 통해 배출된다.Here, when the rotary cylinder 5 connected to the drive shaft 8 by the operation of the motor 11 is rotated at 2,700 ~ 10,000rpm, the molten metal 3 in the rotary cylinder is moved to the outside by the centrifugal force of the rotary cylinder, the fine wire nozzle ( Discharge through 5-1).
그리고, 전자변(6)이 개방되면서 가스공급라인(16)을 통해 불활성가스(Ar,N2등)가 공급되면 이 불활성가스는 가스분사링(15)의 상부를 통해 분사되면서 세선노즐(5-1)로 배출되는 세선(13)을 냉각시키는 동시에 산화를 방지하게 된다.In addition, when the inlet gas (Ar, N 2, etc.) is supplied through the gas supply line 16 while the electron valve 6 is opened, the inert gas is injected through the upper portion of the gas injection ring 15 and has a fine wire nozzle (5-). The fine wire 13 discharged to 1) is cooled and at the same time prevents oxidation.
이때, 세선노즐(5-1)을 통해 생산되는 세선(13)은 진공쳄버(4)의 하부에 쌓이게 되고, 일정량 누적되면 수거하여 제품화하게 된다.At this time, the thin wire 13 produced through the thin wire nozzle 5-1 is accumulated in the lower portion of the vacuum chamber 4, and when a predetermined amount is accumulated, it is collected and commercialized.
한편, 금속세선(13)의 직경을 결정하는 세선노즐(5-1)의 내경을 조절할 경우 다양한 직경의 금속세선을 생산할 수 있게 된다.On the other hand, when adjusting the inner diameter of the fine wire nozzle (5-1) to determine the diameter of the fine metal wire 13, it is possible to produce a fine metal wire of various diameters.
본 발명은 짧은 시간내에 금속세선의 대량생산이 가능하고, 세선의 생산비용을 현저히 낮출 수 있게 되며, 다양한 직경의 금속세선을 선택적으로 생산할 수 있는 효과를 제공하게 된다.The present invention enables mass production of fine metal wires in a short time, significantly lowers the production cost of fine wires, and provides the effect of selectively producing fine wires of various diameters.
