그 중에서도 상기 압축기는 에베퍼레이터에서 증발한 냉매가스를 흡입,압축하여 고온,고압의 냉매가스를 다시 컨덴서측으로 보내는 역할을 하는 것으로서 크게 왕복식과 회전식으로 분류되고, 왕복식은 다시 크랭크식과 사판식으로 분류되어 진다.Above all, the compressor sucks and compresses the refrigerant gas evaporated from the evaporator and sends the high temperature and high pressure refrigerant gas to the condenser side. The compressor is classified into reciprocating type and rotary type. It is done.

이상에서와 같은 사판식 압축기는 샤프트(10)와 결합되어 회전하는 사판(12)이 그 역할을 충실히 실행해야 하므로 단조 공법을 이용하여 제조하였다.The swash plate type compressor as described above was manufactured using a forging method because the swash plate 12 rotated in combination with the shaft 10 should faithfully perform its role.
참조된 도 2는 사판식 압축기의 사판을 제조하는 흐름을 보여주고 있는 것으로서, Hi-Si계 Al 합금을 용융하는 공정과, 용융된 Al합금을 원통형의 긴 잉곳으로 제조하는 공정과, 상기 제조된 잉곳을 사판을 제조하기 위해 적합한 직경을 갖도록 길게 압출하는 공정과, 상기 압축된 잉곳을 동일한 크기로 절단하는 공정과, 상기 절단된 잉곳을 사판의 형상이 되도록 단조하는 공정과, 상기 잉곳을 단조하여 형성된 사판이 압축기에 필요로하는 내식성 및 내마모성을 갖도록 열처리하는 공정과, 상기 열처리된 사판에 샤프트와 결합된 통공을 형성하는 가공 및 그 일단부에 슈가 결합될 수 있도록 슈면을 황삭하는 공정과, 상기 슈가 접하는 슈면을 정밀하게 가공하는 정삭 공정과, 상기 정삭된 슈면을 연마하는 공정과, 상기 사판에 형성된 슈면에 슈가 접하여 원할한 동작을 할 수 있도록 주석도금하는 공정으로 이루어진다.Referring to Figure 2 shows the flow of manufacturing the swash plate of the swash plate type compressor, the process of melting the Hi-Si-based Al alloy, the process of manufacturing the molten Al alloy in a cylindrical long ingot, Extruding the ingot to have a suitable diameter for producing a swash plate, cutting the compressed ingot to the same size, forging the cut ingot to have the shape of a swash plate, and forging the ingot. A process of heat-treating the formed swash plate to have corrosion resistance and abrasion resistance required by the compressor, a process of forming a through hole coupled to the shaft in the heat-treated swash plate, and a process of roughing the shoe surface so that the shoe can be coupled to one end thereof; The shoe is in contact with a finishing process for precisely machining the shoe surface in contact with the shoe, a process of polishing the finished shoe surface, and a shoe surface formed on the swash plate. Tin comprises a step of plating to the actions.
그러나, 상기 사판의 재질을 Hi-Si계 Al 합금을 사용할 경우 취급이 어렵고, 소재의 단가가 일반주조재에 비해 상대적으로 비싸며, 상기 Al합금의 경우 매우 경하므로 단조시에 정확한 형상으로 가공하기가 까다로운 단점이 있었다.However, it is difficult to handle the material of the swash plate when using a Hi-Si-based Al alloy, the unit cost of the material is relatively expensive compared to the general casting material, and the Al alloy is very hard to be processed into an accurate shape during forging. There was a tricky disadvantage.
또한, 절삭가공시에도 일반 가공툴로는 불가능하여 고가인 인조다이아몬드 절삭용 툴을 사용하여야 하므로 마모특성을 향상시키는 초정 Si입자들이 정삭가공중 깨지게 되어 조도가 나빠지고, 마모특성의 저하를 야기하는 문제점이 있었다.In addition, even when cutting, it is impossible to use a general machining tool, and expensive artificial diamond cutting tools should be used. Therefore, primary Si particles that improve wear characteristics are broken during finishing, resulting in poor roughness and deterioration of wear characteristics. There was a problem.
그리고, 표면을 고가의 인조다이아몬드 연마용 툴로 연마하여야 하고 연질마모특성을 위하여 표면에 주석도금을 해야 하므로 공정이 복잡한 단점이 있었다.In addition, the surface has to be polished with an expensive artificial diamond polishing tool, and tin plating is required on the surface for soft wear characteristics.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 종래의 단조공정에서 주조방법을 이용하여 사판을 제조함으로서 제조공정 및 가공량을 줄이고 소재를 일반 범용 Al 다이캐스팅 소재로 대체하여 소재비를 줄임과 동시에 연질마모특성이 우수한 테프론 소재를 코팅하여 마모특성의 향상을 꾀할 수 있는 자동차용 에어콘 압축기 사판의 제조방법을 제공하는 것을 그 목적으로 한다.Therefore, the present invention has been made to solve the above problems, by manufacturing the swash plate using the casting method in the conventional forging process, reducing the manufacturing process and processing amount and replacing the material with a general-purpose Al die-casting material The purpose of the present invention is to provide a method for manufacturing an air conditioner compressor swash plate for automotive that can improve the wear characteristics by coating a Teflon material having excellent soft wear characteristics at the same time.
