본 고안은 송, 배수관로를 개폐하게 되는 볼을 진구상태로 로링(rolling) 가공하기 위한 밸브용 개폐볼의 가공장치에 관한 것이다.The present invention relates to a processing device of the opening and closing ball for valves for rolling the ball to open and close the water, the drain pipe in a spherical state.
이러한 종류의 종래기술은 가공하기 위한 제품의 규격에 부합되는 라운딩면을 로울러를 볼에 압접시킨 상태로 회전시킴에 따라, 볼의 외주면을 선삭상태로 부터 진구상태로 다듬질 가공하여 볼의 구면작동을 원활히 하도록 하였다.This type of prior art rotates the rounding surface conforming to the specifications of the product to be processed while the roller is pressed against the ball, thereby trimming the outer circumferential surface of the ball from the turning state to the true state. It worked smoothly.
그러나 상기 기술은 볼의 외주면과 가공 로울러의 외주면에 서로 접촉된 상태로 구동되므로, 면과면이 접촉된 전부분에 걸쳐 부하가 걸리게 되어 대단히 큰 힘의 토오크를 요구하게 되었고, 볼에 비해 강도가 높은 초경재질로 로울러를 형성하였을 경우에도 마모율이 심하여 자주 교체를 해야되는 비경제적인 단점이 있다.However, the technique is driven in contact with the outer circumferential surface of the ball and the outer circumferential surface of the processing roller, so that the load is applied to the entire surface where the surface and the surface are in contact with each other, requiring a very large torque, and the strength is higher than that of the ball. Even when the roller is formed of a high cemented carbide material, there is an uneconomical disadvantage that the wear rate is severe and frequent replacement is required.
본 고안은 이러한 종래의 제반결함을 해결하기 위해 안출한 것으로, 볼의 외주면을 가공하게 되는 로울러를 일정한 두께를 갖는 원판형으로 성형하되 이의 외주면과 볼의 외주면이 서로 점접촉 상태로 압접되게 하여 구동되게 함에 따라, 로링가공에 따른 회전 토오크를 극소화 시킬 수 있게 됨과 동시에 마모를 방지할 수 있도록 하였는바, 이하 본 고안의 구조를 첨부도면에 의거하여 설명하면 다음과 같다.The present invention was devised to solve the above-mentioned general defects, and the roller which processes the outer circumferential surface of the ball is formed into a disk shape having a certain thickness, but the outer circumferential surface and the outer circumferential surface of the ball are driven by point contact with each other. In order to minimize the rotational torque according to the rolling process and at the same time to prevent wear, the structure of the present invention will be described below based on the accompanying drawings.
기판(1) 중앙으로 고정 설치한 지지로울러(2)의 양측 부위에 안내봉(5)을 설치하여 지지구(4)를 미끄럼 접합하되 일측으로 탄발스프링(6)을 개입하고, 지지구(4) 상부면으로 입설된 지지편(4)에 원판형의 가공로울러(3)를 축착하여 후단으로 접합된 모터(7)에 의해 구동되게 하며, 지지로울러(2)의 상부로 유압실린더(9)에 유착된 작동간(8)을 위치되게 하였다.Guide rods 5 are installed at both sides of the support roller 2 fixedly installed at the center of the substrate 1 to slide the support 4 together, but through the ball spring 6 to one side, and the support 4 ) A disk-shaped processing roller 3 is affixed to the support piece 4 placed in the upper surface and driven by a motor 7 joined to the rear end, and the hydraulic cylinder 9 is placed on top of the support roller 2. The operating rod 8 adhered to is positioned.
상술한 바와같은 구성으로된 본 고안의 작용 및 효과에 있어서, 기판(1)의 중앙부위에 고정된 지지로울러(2)는 이의 상부로 접촉되는 개폐볼의 구면과 동일한 호형홈을 갖게 되고, 상시 지지로울러(2)의 양측 부위에 서로 대칭 되게 미끄럼 접합된 지지구(4)는 안내봉(5)상에서 탄발스프링(6)의 탄발력에 의해 내향으로 슬라이딩됨에 따라, 지지로울러(2)에 롤링가공을 하기 위한 볼을 주입할시에 지지구(4)에 축착한 가공로울러(3)의 외주면이 볼의 최대반경을 이루는 외주면에 밀착된다.In the operation and effect of the present invention having the configuration as described above, the support roller 2 fixed to the central portion of the substrate (1) has the same arc-shaped groove as the spherical surface of the opening and closing ball in contact with the top thereof, The support 4 which is slidably symmetrically coupled to both sides of the support roller 2 is slid inward by the elastic force of the ball spring 6 on the guide rod 5, thereby rolling on the support roller 2. At the time of injecting the ball for processing, the outer circumferential surface of the processing roller 3 fixed to the support 4 is in close contact with the outer circumferential surface forming the maximum radius of the ball.
이에 따라 모터(7)를 구동시키어 가공로울러(3)를 회동시키게 되면, 가공로울러(3)의 외주면이 볼의 외주면에 점접촉되며, 지지로울러(2) 상에서 볼을 공전시키게 되고, 유압실린더(9)를 작동시켜 볼에 관통된 통공에 삽지한 작동간(8)을 요동시키게 되면 상기한 공전작용과 더불어 볼이 자전되므로, 볼의 외주면 전체가 선삭상태로 부터 진구상태로 가공되는데, 이때 작동간(8)의 요동범위는 제3도에 점선으로 나타낸 바와 같이 40°정도의 범위내에서 표면가공을 만족시킬 수 있다.Accordingly, when the machining roller 3 is rotated by driving the motor 7, the outer circumferential surface of the processing roller 3 is in point contact with the outer circumferential surface of the ball, and the ball is revolved on the support roller 2, and the hydraulic cylinder ( 9) By operating the swinging operation section 8 inserted into the through-hole through the ball, the ball rotates with the above-mentioned idle action, so the entire outer circumferential surface of the ball is machined from the turning state to the true state. The fluctuation range of the liver 8 can satisfy the surface finish within the range of about 40 ° as indicated by the dotted line in FIG.
그리고 제4도와 같이 볼의 외주면 일측으로 키홈이 형성된 경우에 가공을 할 시에는 가공로울러(3)의 외주면에 요입홈(3')이 형성된 것으로 교체하여 사용하게 되면, 제5도의 (a) 및 (b)와 같이 요입홈(3')의 양측으로 돌출된 부분 중 일측부분이 볼의 외주면에 접촉되므로, 키홈에 의한 볼의 공전 및 자전의 저해 요인을 해결하게 됨과 동시에 키홈에 가해지는 마모 및 국부적인 롤링을 방지하여 정밀한 상태의 표면가공을 하게 된다.When the key groove is formed at one side of the outer circumferential surface of the ball as shown in FIG. As shown in (b), since one side portion of the protruding portion of the recessed groove 3 'is in contact with the outer circumferential surface of the ball, it is possible to solve the deterioration factors of the ball revolution and rotation by the key groove and at the same time wear and It prevents local rolling and gives a precise surface finish.
이와 같은 본 고안은 로링가공에 소요되는 회전 토오크를 극소화 시킴에 따라 전력의 소모를 절감할 수 있게 되고, 값이 고가인 초경질의 가공로울러의 마모를 방치할 수 있는 경제적인 잇점이 있다.The present invention can reduce the power consumption by minimizing the rotational torque required for roring processing, and there is an economical advantage to prevent wear of the ultra-hard processing roller, which is expensive.
