Description
본 발명은 자동차 등속조인트용 볼케이지의 제조공법에 관한 것으로서 더욱 상세하게는 볼케이지의 제조시 전조다이와 멘드럴(Mandrel)을 이용하여 제조하므로 제조공정을 간소화하기위함이다.The present invention relates to a manufacturing method of a ball cage for a constant velocity joint for automobiles, and more particularly, to simplify the manufacturing process because it is manufactured by using a rolling die and a mandrel (Mandrel) when manufacturing the ball cage.
자동차의 동력전달장치의 하나인 등속조인트는 변속기의 회전력을 구동바퀴로 전달하는 것으로서 그 구성은 제1도에 도시된 바와 같이 구(球)형의 내면을 가지는 아우터레이스(outer race ; 10)에 외경이 구(球)면을 가지는 이너레이스(inner race ; 11)가 장착된다.The constant velocity joint, which is one of the power transmission devices of the automobile, transmits the rotational force of the transmission to the driving wheel, and its configuration is shown in the outer race 10 having a spherical inner surface as shown in FIG. An inner race 11 having an outer diameter of a spherical surface is mounted.
상기 이너레이스(11)에는 등간격으로 6개의 스틸볼(12)이 안착되는 안내홈을 가지고, 상기 스틸볼(12)의 정확한 위치를 유지하기위해서 이너레이스(11)의 외주연에 볼케이지(13)가 구비된다.The inner race 11 has a guide groove in which six steel balls 12 are seated at equal intervals, and a ball cage is formed on the outer circumference of the inner race 11 to maintain the correct position of the steel ball 12. 13).
이와 같이 구성된 등속조인트(1)의 토크전달은 6개의 스틸볼(12)의 접촉점으로 이루어지게 되고, 이는 전륜구동자동차에 주로 사용되며 스트로크가 없는 조인트 연결에 사용된다.Torque transmission of the constant velocity joint (1) configured as described above is made of a contact point of the six steel ball 12, which is mainly used in all-wheel drive vehicles and is used for joint connection without stroke.
상기 등속조인트(1)는 스틸볼(12)의 회전에 의한 토크를 전달하게되고, 이로 인해 스틸볼에는 항상 고속회전에 의한 유동이 발생하게되고, 이를 보정하는 역할을 하는 것이 바로 볼케이지다.The constant velocity joint 1 transmits the torque due to the rotation of the steel ball 12, which causes the steel ball to always flow due to the high-speed rotation, which serves to correct the ball cage.
상기와 같은 볼케이지는 제2도에 도시된 바와 같이 크게 두 가지의 제조 방법으로 주로 생산이 되는데, 그 중 한 가지는 두께가 얇은 강관을 외주연과 내경을 선반과 같은 선삭가공기를 이용하여 완전히 가공한 후, 볼케이지의 폭만큼 절단한 다음 프레스를 이용하여 굴곡부를 형성하게된다.As shown in Figure 2, the ball cage is mainly produced by two manufacturing methods, one of which is a thin steel pipe, the outer periphery and the inner diameter is completely processed using a turning machine such as a lathe. After that, the width of the ball cage is cut and then a bend is formed by using a press.
상기 제조공정을 간단히 살펴보면; 원자재 → 1차선삭가공(외주연가공 ; 10) → 2차선삭가공(내경가공 ; 11) → 절단공정(12) → 1차 프레싱가공(일측에 라운드형성 ; 13) → 2차 프레싱가공(외주연에 굴곡부 형성 ; 14) → 마무리 가공(15)으로 진행한다.Briefly look at the manufacturing process; Raw material → 1st line cutting (outer peripheral processing; 10) → 2nd line cutting (inner diameter processing; 11) → cutting process (12) → 1st pressing processing (round forming on one side; 13) → 2nd pressing processing (others Forming bends at the periphery 14) → proceeding to finishing (15).
상기와 같은 프레싱에 의한 제조공정이외에도 두께가 두꺼운 강관을 이용하여 볼케이지 폭만큼 절단한 후 외주연과 내경의 굴곡부를 선삭에 의해서 가공하는 방법이 있다.In addition to the manufacturing process by pressing as described above, there is a method of cutting the curved portion of the outer circumference and the inner diameter by cutting the ball cage width by using a thick steel pipe and then turning.
상기와 같은 프레싱에 의한 제조방법은 많은 수의 금형을 필요로 하게되고, 또한 대형프레스가 필요하며, 공정이 복잡하여 제조시간이 길어져 생산성이 저조한 단점이 있으며, 선삭에 의한 제조방법은 자재의 낭비와 가공비가 많이 소요되는 문제점이 있었다.The manufacturing method by pressing as described above requires a large number of molds, and also requires a large press, and the manufacturing process is complicated due to a complicated process, resulting in low productivity. The manufacturing method by turning is a waste of materials. There was a problem that takes a lot of processing costs.
이에 본 발명에서는 상기한 여러 가지의 문제점을 해결하기위해서 안출된 것으로서 얇은 강관을 이용하여 내, 외경을 가공한 후 2개의 전조다이와 하나의 중심축을 이용하여 볼케이지를 제조함으로서 공정의 수를 단축할 수 있고 제조원가를 절감하기위함이다.In the present invention, to solve the various problems described above, after processing the inner and outer diameter using a thin steel pipe to reduce the number of processes by manufacturing a ball cage using two rolling dies and one central axis. To reduce manufacturing costs.

이하 첨부되는 도면과 관련하여 본 발명의 제조공정을 설명하면 다음과 같다.Hereinafter, the manufacturing process of the present invention will be described with reference to the accompanying drawings.
제3도는 본 발명이 적용된 볼케이지의 제조방법을 도시한 단면도, 제4도는 본 발명에 의한 제조공정을 도시한 제조흐름도로서 함께 설명을 한다.3 is a cross-sectional view showing the manufacturing method of the ball cage to which the present invention is applied, and FIG. 4 is a manufacturing flow chart showing the manufacturing process according to the present invention.
자동차 동력전달장치중에 하나인 등속조인트의 이너레이스외주연에 위치하며, 스틸볼의 위치보정을 위해서 구비되는 볼케이지를 전조다이를 이용한 전조공법으로 제조한다.Located in the outer race of the inner race of the constant velocity joint, one of the automobile power transmission devices, the ball cage provided for the position correction of the steel ball is manufactured by a rolling method using a rolling die.
상기 전조를 위해서는 제3도에 도시된 바와 같이 2개의 전조다이(20,20')와 하나의 중심축(Mandel ; 21)을 이용하여 작업을 수행하게 된다.For the rolling, as shown in FIG. 3, two rolling dies 20 and 20 'and one central axis 21 are performed.
상기 전조다이(20)는 볼케이지(13)의 외주연의 굴곡부형성에 필요한 굴곡부(22)를 가지고, 중심축(21)에는 볼케이지내경의 굴곡부(23)를 형성하기위해 돌출부(24)를 가진다.The rolling die 20 has a bent portion 22 necessary for forming the bent portion of the outer circumference of the ball cage 13, the central axis 21 is formed with a protrusion 24 to form a bent portion 23 of the ball cage inner diameter Have
상기 구성을 이용하여 다음과 같은 제조공정을 거쳐 등속조인트용 볼케이지를 제조하게 되는데; 원자재 → 1차선삭(내, 외경의 가공 ; 30) → 절단공정(31) → 중심축삽입 및 전조다이고정(32) → 전조다이 압축(33) → 마무리 가공(34) → 완제품으로 공정을 완료한다.The ball cage for the constant velocity joint is manufactured by the following manufacturing process using the above configuration; Raw materials → first-line turning (machining of inner and outer diameters; 30) → cutting process (31) → inserting the central shaft and rolling die (32) → rolling die compression (33) → finishing (34) → finishing the process with finished products do.
상기 공정에 대하여 간단히 부연하면; 1차선삭(30)을 이용하여 강관의 내, 외경을 가공하여 이물질을 제거하고, 절단공정(31)은 일체로 된 긴 강관을 볼케이지의 폭과 동일하게 하나 씩 절단하는 것을 말하며, 중심축삽입 및 전조다이고정(32)은 절단된 강관의 내경에 중심축을 삽입하고, 전조다이의 내경에 강관을 고정시키는 것을 가르킨다.Simply explaining the process; The inner and outer diameters of the steel pipe are processed using the primary turning 30 to remove foreign substances, and the cutting process 31 refers to cutting the integral long steel pipe one by one to be equal to the width of the ball cage. Insertion and rolling die fixing 32 indicates inserting a central axis into the inner diameter of the cut steel pipe and fixing the steel pipe to the inner diameter of the rolling die.
상기와 같이 강관이 고정된 상태에서 전조다이를 압축하면 강관과 전조다이, 중심축이 상호 밀착하면서 볼케이지를 형성하게된다.As described above, when the rolling die is compressed while the steel pipe is fixed, the steel pipe, the rolling die, and the central axis are in close contact with each other to form a ball cage.
상기에서 살펴본 바와 같이 전조공법을 이용하여 제조할 경우 생산시간의 단축과 장비의 간소화등 많은 이점을 얻게된다.As described above, when manufacturing by using a rolling method, there are many advantages such as shortening of production time and simplification of equipment.
이상과 같이 진행하는 본 발명인 자동차 등속조인트용 볼케이지의 제조공법은 공정의 수를 감소시켜 생산성을 향상시킬 수 있으며, 가공비의 절감으로 제조단가의 하락을 가져오는 유용한 발명이다.The manufacturing method of the ball cage for automobile constant velocity joints of the present invention proceeds as described above is a useful invention that can reduce the number of processes to improve productivity, bringing down the manufacturing cost by reducing the processing cost.
