Description
본 발명은 와이어 방전가공용 황동전극선을 제조하기 위한 방법에 관한 것으로, 보다 상세하게는 본 발명은 구리 및 아연 합금 소재에 알루미늄을 첨가하여 조직의 미세화 및 안정화를 통해 와이어 가루 발생의 억제를 하는 한편, 종래의 황동선보다 인장강도를 향상시켜 각 설비별 최적의 가공조건을 조합시켜 가공속도 및 자동결선성이 향상되어 와이어 컷팅 작업시 무인화 작업이 가능하도록 하는 효과를 제공한다. 본 발명은 이와 같은 효과를 갖는 와이어 방전가공용 황동전극선 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a brass electrode wire for wire discharge machining, and more particularly, the present invention is to suppress the generation of wire powder through the refinement and stabilization of the structure by adding aluminum to the copper and zinc alloy material, The tensile strength is improved compared to the conventional brass wire, and the optimum processing conditions for each facility are combined to improve the processing speed and the automatic connection, thereby providing the effect of enabling the unmanned operation during the wire cutting operation. The present invention relates to a brass electrode wire manufacturing method for wire discharge machining having such an effect.
일반적으로 방전가공용 전극선은 와이어 방전가공기에 사용되는 소모성 전극선이다. 와이어 방전가공은 가공물과 전극선에 +, -전기를 통해 발생되는 전하량에 따라 금속을 녹여 가공하여 생산되어 왔으며, 이러한 와이어 방전가공 기술은 절삭가공이 난이한 난삭재 및 고경도의 열처리가 된 금형재료의 가공과 비대칭 형상의 금형가공기술에 절대적인 영향을 끼치고 있으며, 산업기술의 발전에 따라 금형기술 또한 발전되어 금형의 정밀도향상과 가공속도의 향상을 위해 끊임없이 와이어 방전가공용 전극선의 발전을 가져왔다.In general, electrode lines for electric discharge machining are consumable electrode wires used in wire electric discharge machines. Wire electric discharge machining has been produced by melting and processing metals according to the amount of electric charge generated through + and-electricity on workpieces and electrode wires. Such wire electric discharge machining technology is difficult to cut and mold materials with high hardness heat treatment. It has an absolute influence on the processing and the asymmetrical mold processing technology. As the industrial technology has developed, the mold technology has also been developed, which has led to the continuous development of the electrode wire for wire discharge machining in order to improve the precision of the mold and improve the processing speed.
상기 와이어 방전가공용 전극선은 방전을 잘 발생시키기 위해 은, 구리와 같은 전기 전도도가 높은 금속이 방전효과가 높았으나, 방전가공시 발생되는 공작물이 용해된 방전흔을 빨리 배출시키기위해 기화 및 폭발력이 높은 아연이 함유된 황동(구리와 아연의 합금)와이어가 주로 사용되고 있다.The electrode for wire discharge machining has a high discharging effect of a metal having high electrical conductivity such as silver and copper in order to generate a discharge well, but has a high vaporization and explosive force in order to quickly discharge a discharge trace in which a workpiece generated during discharge processing is dissolved. Zinc-containing brass (alloy of copper and zinc) wire is mainly used.
상기 황동와이어는 원소재의 구리 및 아연의 구성비를 다르게 하여 전기전도도와 와이어의 강도향상 및 가공속도의 향상을 위해 아연의 함량을 증가시켜 왔으나, 아연의 함량을 증가시키면 와이어의 냉간 가공성이 떨어져 중량대비 40%이상의 아연을 조성한 소재를 이용한 와이어컷팅용 전극선을 생산하지 못하고 있다.The brass wire has increased the content of zinc to improve the electrical conductivity and the strength of the wire and improve the processing speed by varying the composition ratio of copper and zinc of the raw material, but if the content of zinc is increased, the cold workability of the wire is reduced It is unable to produce wire cutting electrode wires using a material with more than 40% zinc.
또 다른 방법으로 표면에 6um 내지 15um의 아연층을 생성한 뒤 확산열처리를 실시한 후, 신선공정을 거쳐 최종와이어 전극선의 표면에 2um 내지 3um의 순수 아연도금층 및 확산 황동 도금층으로 이루는 와이어가 대부분이다.As another method, after forming a zinc layer of 6um to 15um on the surface and performing a diffusion heat treatment, most wires are composed of a pure zinc plating layer and a diffusion brass plating layer of 2um to 3um on the surface of the final wire electrode line through a drawing process.
따라서 황동의 모선에 아연을 도금한 피복용 와이어 전극선으로서는 가공속도, 제품의 정밀도 향상 및 인한 무인화 가공을 위한 자동결선율의 향상을 위해 기존의 황동선 및 황동을 심선으로 하고 아연을 코팅한 피복용 전극선으로서는 금형 가공시 단선과 직진도의 저하로 자동결선 실패율이 증가하여 자동화 및 무인가동을 할수 없는 문제점이 있었다.Therefore, as a coating wire electrode wire coated with zinc on brass busbars, a coating electrode wire made of existing brass wire and brass as core wire and zinc coated for improvement of processing speed, product accuracy, and automatic connection rate for unattended processing As a result, there was a problem in that automatic connection failure rate was increased due to a decrease in disconnection and straightness during mold processing, and thus automation and unauthorized operation were not possible.
또한, 와이어를 구성하고 있는 원재료의 조성이 동 및 동합금으로 이루어진 소재의 인장강도와 동과 아연의 결합조직으로 구성된 금속의 특성한계로 인장강도를 증가시키는데 문제점이 있었다.In addition, the composition of the raw material constituting the wire has a problem in increasing the tensile strength due to the characteristic strength of the metal composed of a copper and zinc alloy and the tensile strength of the material consisting of copper and copper alloy.
또한, 산업이 고도로 발전하면서 와이어 방전가공을 이용한 금형 가공산업이 급속도로 발전하여 고정밀도와 무인화 가공을 위한 자동결선율의 향상을 요구하는 와이어 및 그 제조방법이 제공되지 못하는 문제점이 있었다.In addition, as the industry is highly developed, the die processing industry using wire discharge machining has rapidly developed, and there is a problem in that a wire and a method of manufacturing the same, which require improvement of an automatic connection rate for high precision and unattended processing, are not provided.
