일반적으로 냉동사이클을 수행하는 에어콘이나 냉장고 등과 같은 냉동장치에는 압축기가 적용되는데, 이와 같은 압축기는 여러 가지 종류가 있으나, 특히 로타리 압축기는 냉매를 작동유체로 하여 압축, 응축, 팽창, 증발과정을 연속, 반복적으로 수행하는 냉동장치에서 냉매를 고압으로 압축시키기 위해 사용되며, 압축기 내에는 회전축에 윤활과 냉각을 위하여 오일을 공급해주는 오일픽업장치가 구비된다.Generally, a compressor is applied to a refrigerating device such as an air conditioner or a refrigerator that performs a refrigeration cycle. There are various types of such compressors. In particular, a rotary compressor continuously compresses, condenses, expands, and evaporates a refrigerant using a working fluid. In order to compress the refrigerant to a high pressure in a refrigerating apparatus repeatedly performed, an oil pick-up apparatus is provided in the compressor to supply oil for lubrication and cooling to a rotating shaft.

And an oil pickup frame for supplying each friction part inside the compressor.

도 1 은 이와 같은 오일 픽업 프레임(10)을 도시하고 있다.1 shows such an oil pickup frame 10.

상기 오일 픽업 프레임(10)은 금속재로 제조되는데, 하단에 서로 반대 방향으로 절곡된 고정부(11)를 구비하고, 나선형으로 형성된 제1나선부(12) 및 제2나선부(13)가 각각 형성되어 있다.The oil pickup frame 10 is made of a metal material, and has a fixing portion 11 bent in opposite directions at the bottom thereof, and the first spiral portion 12 and the second spiral portion 13 formed in a spiral shape are respectively formed. Formed.

그리고, 상기 제1나선부(12)와 제2나선부(13)는 서로 5°정도 기울기를 두고 형성되어 있다.The first spiral portion 12 and the second spiral portion 13 are formed to be inclined by about 5 ° with each other.

종래에 이와 같은 오일 픽업 프레임의 제조방법은 도 2에 도시하고 있는데, 이는 소재를 적정 치수로 블랭킹하는 블랭킹공정(21), 블랭킹된 제품 소재의 고정부(11)를 절곡하는 제1밴딩공정(22), 이어서 몸체의 제1나선부(12)를 일부 밴딩하는 제2밴딩공정(23) 및 제2나선부(13)를 밴딩하여 전체를 나선형으로 밴딩하는 제3밴딩공정(24)을 수행하고, 다시 밴딩된 오일 픽업 프레임(10)의 제2나선부(13)를 제1나선부(12)에 대하여 5°정도 밴딩하는 제4밴딩공정(25)을 수행하고, 제품을 완성(26)하게 된다.Conventionally, such a method of manufacturing an oil pickup frame is illustrated in FIG. 2, which is a blanking process 21 for blanking a material to an appropriate dimension and a first bending process for bending the fixing part 11 of a blanked product material ( 22) Next, a second bending process 23 for partially bending the first spiral portion 12 of the body and a third bending process 24 for bending the whole of the second spiral portion 13 in a spiral manner. In addition, a fourth bending process 25 of bending the second spiral portion 13 of the bent oil pick-up frame 10 about 5 ° with respect to the first spiral portion 12 is performed to complete the product (26). )

이때, 상기 블랭킹공정(21)에서는 도 3 에 도시한 바와 같이 원판(30)에서 적정의 치수로 제품 소재(31)를 블랭킹 가공하게 된다.At this time, in the blanking step 21, as shown in FIG. 3, the blank material 30 is blanked to a suitable dimension.

그러나, 이와 같은 종래의 제조 방법은 원판에서 제품 소재를 블랭킹 가공하므로 재료의 로스(Loss)율이 상승되어 제조 원가를 상승시키는 요인으로 작용할 뿐만 아니라 블랭킹 가공시 가공면에 버(burr)가 발생되는 문제점이 내재되어 있으며, 블랭킹 가공시 원소재의 압연 방향과 직각되는 방향으로 제품 소재가 형성되어 파손, 크랙 등의 이유로 내구성이 저하되는 문제점들이 있고, 특히 몸체를 제1 및 제2나선부로 나누어 밴딩을 행하므로 불안정하여 불량률이 상승(수율 20%)되는 문제점이 있었다.However, such a conventional manufacturing method blanks the product material in the original plate, so that the loss rate of the material is increased, which not only acts as a factor in increasing the manufacturing cost, but also causes burrs on the processed surface during blanking. Problems are inherent, and there is a problem in that the product material is formed in a direction perpendicular to the rolling direction of the raw material during blanking processing, and thus durability is lowered due to breakage or cracking, and in particular, the body is divided into first and second spiral parts. There was a problem in that it was unstable and the defective rate was raised (yield 20%).

따라서 본 발명은 상술한 종래 기술의 문제점들을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 제조 공정을 단축하여 생산성을 향상시키고 제조 원가를 절감하고, 띠상의 원재료를 사용하여 재료 로스율을 감소시킴과 아울러 제품의 풀질을 균일화하고 내구성을 증대시킬 수 있는 압축기용 오일 픽업 프레임의 제조방법을 제공하는데 있다.Therefore, the present invention has been invented to solve the above-mentioned problems of the prior art, and an object of the present invention is to shorten the manufacturing process to improve productivity and reduce manufacturing cost, and to reduce the material loss rate by using band-shaped raw materials. In addition, the present invention provides a method of manufacturing an oil pick-up frame for a compressor that can improve the quality of a product and improve its durability.

When the second bending process 44 for bending (13) about 5 ° is performed, the oil pickup frame 10 is completed 45.

이와 같은 각 공정은 하나의 스테이션에서 이루어지는 것이 가능케 되어 더욱 작업 속도를 증가시킬 수 있게 된다.Each of these processes can be done in one station, further increasing work speed.

상기 커팅공정(41)에서는 도 5 에 도시한 바와 같이 띠상의 원소재(50)에서 제품소재(51)를 커팅하게 되며, 이는 종래에서와 같이 블랭킹 가공을 하지 않고 커팅만 수행하므로 재료의 로스율이 감소되고, 원소재(50)의 압연방향(길이방향)과 동일한 방향으로 제품소재(51)의 압연방향이 이루어짐으로써 파손, 크랙 등의 발생이나 재질의 변형 등이 최소화되고, 이에 따라 내구성이 더욱 향상된다.In the cutting process 41, the product material 51 is cut from the band-shaped raw material 50, as shown in FIG. 5, and the loss rate of the material is reduced since only the cutting is performed without the blanking process as in the prior art. It is reduced, and the rolling direction of the product material 51 is made in the same direction as the rolling direction (length direction) of the raw material 50, thereby minimizing the occurrence of breakage, cracks, deformation of the material, etc., thereby further durability Is improved.

또한, 상기 커팅공정(41)에서는 종래와 같이 버(burr)의 발생도 전혀 발생되지 않는다.In addition, in the cutting step 41, the occurrence of burrs does not occur at all as in the prior art.

한편, 상기 소성가공공정(43)은 도 6에 도시한 바와 같이 고정부(52)가 고정된 상태에서 소성가공수단(60)에 의해 나선형의 가공이 이루어지게 된다,On the other hand, the plastic processing step 43 is a spiral processing is performed by the plastic processing means 60 in a fixed state 52 as shown in Figure 6,

즉, 상기 제품소재(51)의 고정부(52)가 고정된 상태에서 상기 소성가공수단(60)가 도면에서 A방향으로 진입한 후 B방향으로 후퇴하면서 회전되면 나선형으로 소성가공이 이루어지게 된다.That is, when the plastic processing means 60 enters the A direction in the drawing and then retracts in the B direction while the fixing part 52 of the product material 51 is fixed, plastic processing is performed in a spiral manner. .

상기 소성가공수단(60)은 도 7에 도시한 바와 같이 회전축(61)의 일단에 제품소재(51)가 삽입되는 삽입부(62)가 형성되어 있고, 그 외주면에는 나선형의 나선홈(63)이 형성되어 진입 시에는 직선방향으로 진입하고, 후퇴 시에는 상기 나선홈(63)을 따라 가이드되어 나선형으로 회전되면서 후퇴하여 제품소재(51)를 나선형으로 소성 가공하게 된다.As shown in FIG. 7, the plastic processing means 60 has an insertion portion 62 into which a product material 51 is inserted at one end of the rotation shaft 61, and a spiral spiral groove 63 is formed on the outer circumferential surface thereof. Is formed and enters in a straight direction when entering, and when retracted is guided along the spiral groove (63) is rotated in a spiral to retreat to plastic processing the product material 51 in a spiral.

상술한 바와 같이 본 발명에 의하면, 하나의 스테이션에서 각 공정이 일시에 이루어지는 것이 가능하여 제조 시간이 현저하게 단축되고 생산성이 증대되며, 띠상의 원소재를 적용하므로 재료의 로스율이 현저하게 감소될 뿐만 아니라 원소재 및 제품소재의 압연방향이 동일하여 파손 및 크랙의 발생이 최소화되고, 이에 따라 오일 픽업 프레임의 내구성이 향상되고 재질 변형이 최소화되며, 특히 나선형상의 가공을 상기 소성가공수단에 의하여 행하므로 균일한 품질을 얻을 수 있고, 제품의 수율이 98%이상으로 향상되는 한편, 블랭킹 가공을 행하지 않고 커팅 작업을 행하여 제품소재를 얻으므로 버(burr)가 발생되지 않는 등의 여러 가지 효과가 있다.As described above, according to the present invention, each process can be performed at one time at a time, which significantly shortens the production time, increases productivity, and reduces the loss rate of the material by applying a band-shaped raw material. However, since the rolling direction of the raw material and the product material are the same, the occurrence of breakage and cracks is minimized, thereby improving the durability of the oil pickup frame and minimizing material deformation, and in particular, spiral processing is performed by the plastic processing means. The uniform quality can be obtained, the yield of the product is improved to 98% or more, and the cutting material is obtained without performing the blanking process to obtain the product material, so that there are various effects such as no burr.
