The present invention relates to a method of manufacturing a receiver drier tank capable of manufacturing a tank of a receiver drier removing a refrigerant supplied to an evaporator from a cooling cycle, simplifying a manufacturing process using an impact method, and reducing manufacturing costs. The method of manufacturing a receiver drier tank includes: a step of preparing a cylindrical-shaped material (10) which has a diameter larger than that of the receiver drier tank and is short and performing heat treatment on the cylindrical-shaped material (10); a step of placing the material (10) on a first extrusion die (50) and extruding the material (10) into a first formation body (20) which has a solid small diameter part (22) having the same outer diameter as that of the receiver drier tank and a hollow large diameter part (21) having the same outer diameter as that of the material (10) by hitting and pressurizing the upper surface of the material (10) with a first impact punch (55); a step of extruding the first formation body into a second formation body (30) which has a cylindrical shape with a closed lower part by placing the first formation body (20) on a second extrusion die (60) and, hitting and pressurizing the upper end of the small diameter part (22) of the first formation body (20) with a second impact punch (65) with the same outer diameter as that of the inner diameter of the receiver drier tank, and then extruding the small diameter part (22); a step of extruding the second formation body (30) into a third formation body (40) which has a generally uniform diameter of the outer circumferential surface thereof and has a thick circumferential part (41) having an inner diameter smaller than that of the lower part thereof and formed at the inner side of the upper end part thereof by placing the second formation body (30) on the third extrusion die and then hitting and pressurizing the large diameter part (31) with a third impact punch; and a forming a screw thread (42) allowing an end cap to be fastened to the thick circumferential part (41) of the third formation body (40).

    본 발명은 냉동 사이클에서 증발기로 공급되는 냉매의 수분을 제거하는 리시버 드라이어의 탱크를 제조하되, 임팩트 공법을 이용하여 제조 공정을 단순화하고 제조 비용을 절감할 수 있도록 한, 리시버 드라이어 탱크의 제조방법에 관한 것으로서, 목적하는 리시버 드라이어 탱크에 비해 직경은 크고 길이가 짧은 원기둥 형상의 소재(10)를 준비하여 열처리하는 단계; 상기 소재(10)를 1차 압출다이(50)에 거치하고 1차 임팩트 펀치(55)로 상기 소재(10)의 상면을 충격 가압하여 상기 리시버 드라이어 탱크와 동일한 외경을 갖는 중실형 소경부(22) 및 상기 소재(10)와 동일한 외경을 갖는 중공형 대경부(21)를 갖는 제1성형체(20)로 압출 성형하는 단계; 상기 제1성형체(20)를 2차 압출다이(60)에 거치한 후 상기 리시버 드라이어 탱크의 내경과 동일한 외경을 갖는 2차 임팩트 펀치(65)로 상기 제1성형체(20)의 소경부(22) 상단을 충격 가압하여 상기 소경부(22)를 압출 성형함으로써 하부가 막혀 있는 원통 형상의 제2성형체(30)를 형성하는 단계와; 상기 제2성형체(30)를 3차 압출다이에 거치한 후 3차 임팩트 펀치로 대경부(31)를 충격 가압하여 외주면의 직경이 전체적으로 일정하고 상단 부분 내측에 내경이 그 하부에 비해 작은 후육부(41)가 형성된 제3성형체(40)로 압출 성형하는 단계와; 상기 제3성형체(40)의 후육부(41)에 엔드 캡이 체결되는 나사산(42)을 성형하는 단계;를 포함하는 것을 특징으로 한다.
