본 발명은 유체의 압력이 사용 목적에 대하여 너무 높을 때 이를 감압하고 일정하게 압력을 유지시키기 위해 사용되는 감압밸브의 하우징 성형방법에 관한 것으로, 특히, 감압밸브의 하우징을 단조성형방법에 의하여 성형하면서 6방향에서 동시에 입체적으로 단조성형하여 외관미를 향상시키고 생산성을 향상시킴과 동시에 후가공공정을 편리하게 할 수 있도록 하는 감압밸브의 하우징성형방법에 관한 것이다.The present invention relates to a housing forming method of a pressure reducing valve that is used to reduce the pressure when the pressure of the fluid is too high for the purpose of use and to maintain a constant pressure, in particular, while forming the housing of the pressure reducing valve by the forging molding method The present invention relates to a housing forming method of a pressure reducing valve that can be forged three-dimensionally at the same time in six directions to improve appearance and productivity and at the same time make the post-processing process convenient.
일반적으로 사용되고 있는 감압밸브의 하우징성형방법은 하우징의 형상으로 되는 주형내에 쇳물을 붓고 이를 냉각시켜 후가공하는 주조성형방법과, 소재를 하우징형상의 금형이 구비된 프레스기로 프레싱하여 하우징의 외부형상을 성형한 후 후가공하는 단조성형방법이 사용되고 있다.The housing molding method of the pressure reducing valve generally used is a casting molding method in which a molten water is poured into a mold that forms a housing shape, cooled and then processed, and the external shape of the housing is formed by pressing the material with a press equipped with a housing-shaped mold. After forging, a forging method is used.
그러나 종래의 감압밸브 하우징을 성형하는 방법중, 먼저 주조성형 방법은, 유체의 유입홀과 유출홀 및 하부홀과 상부홀을 주조되는 하우징에 일차로 성형하여 후가공을 편리하게 할 수 있는 잇점은 있으나, 유체의 흐름방향등이 표시되는 하우징의 외부 표면이 매우 거칠어서 외관미가 저하되고 냉각시간이 많이 소요되어 생산성이 저하되는 결점이 있었다.However, in the conventional method of molding the pressure reducing valve housing, the first casting molding method has the advantage that the inlet and outlet holes of the fluid and the lower and upper holes are primarily molded into the housing to be cast to facilitate post-processing. In addition, the outer surface of the housing, in which the flow direction of the fluid is displayed, is so rough that the appearance is deteriorated and the cooling time is required, resulting in a decrease in productivity.
한편, 감압밸브 하우징을 성형하는 방법중 또 다른 하나의 방법인 단조성형방법은 상, 하부 금형 2개를 각각 프레스기로 설치하고 소재를 하부금형 위로 공급한 후 프레싱하여 상부금형과 하부금형 사이에서 제 3도와 같은 감압밸브(50)의 하우징(51)이 형성되도록 하는 것이므로 외관미를 향상시킬 수 있었으나, 성형시 하우징(51)의 표면에 유체의 흐름방향등을 표시할 수 없는 결점이 있었다.On the other hand, forging molding method, another method of forming the pressure reducing valve housing is installed between the upper mold and the lower mold by installing two upper and lower molds with a press machine, supplying the material to the lower mold, and pressing them. Since the housing 51 of the pressure reducing valve 50 as shown in FIG. 3 was formed, the appearance beauty could be improved, but there was a drawback in that the flow direction of the fluid cannot be displayed on the surface of the housing 51 during molding.
또한, 상기의 단조성형방법은 후가공의 효율을 조금이라도 높이기 위하여 상부금형과 하부금형의 프레싱에 의해 하우징(51)의 외형과 상부홀 및 하부홀이 형성되도록 한 것이므로 유체의 유입부(52)와 유출부(53)는 성형할 수 없었을 뿐만 아니라, 유입부(52)와 유출부(53)의 외형을 원형으로 성형할 수 없는 결점이 있었다.In addition, the forging method described above is to form the outer shape, the upper hole and the lower hole of the housing 51 by pressing the upper mold and the lower mold in order to increase the efficiency of post-processing even a little, so that the inlet 52 and Not only the outlet 53 could not be molded, but also the defect that the outer shape of the inlet 52 and the outlet 53 could not be formed in a circular shape.
따라서, 본 발명의 목적은 감압밸브의 하우징을 단조성형방법에 의하여 성형하면서 6방향에서 동시에 입체적으로 단조성형하여 상부홀과 하부홀 및 유입홀과 유출홀을 동시에 성형할 뿐만 아니라, 하우징 표면에는 유체의 흐름방향을 표시하면서도 외관미를 향상시킴과 동시에 그만큼 제작공정을 단축시켜 생산성을 향상시키고 후가공공정을 편리하게 할 수 있도록 한 감압밸브의 하우징성형방법을 제공함에 있다.Accordingly, an object of the present invention is to form the upper and lower holes and the inlet and outlet holes at the same time by simultaneously forging three-dimensionally in six directions while forming the housing of the pressure reducing valve by the forging molding method. The present invention provides a method for forming a housing for a pressure reducing valve that improves the appearance while improving the appearance and at the same time shortens the manufacturing process to improve productivity and facilitate the post-processing process.
이러한 본 발명의 목적은 고정금형인 하부금형상에 하우징소재를 위치시킨 후 상부금형을 작동시켜 하우징의 정면과 배면을 성형하고 이와 동시에 정면금형과 배면금형을 작동시켜 하부홀과 상부홀이 동시에 성형되도록 하며, 또한 우측금형과 좌측금형에 의해 유입홀과 유출훌이 역시 동시에 성형되도록 함으로써 감압밸브의 하우징을 3차원적으로 6방향에서 동시에 단조성형하는 것에 의해 이루어진다.The object of the present invention is to place the housing material on the lower mold, which is a fixed mold, and then operate the upper mold to form the front and back of the housing, and simultaneously operate the front mold and the back mold to simultaneously form the lower and upper holes. In addition, the inlet hole and the outlet hole are also simultaneously molded by the right mold and the left mold, thereby simultaneously forging the housing of the pressure reducing valve in six directions in three dimensions.
이하, 본 발명의 바람직한 실시예를 첨부 도면에 의하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
프레스기에 금형을 고정하여 하우징을 성형함에 있어서, 상부금형과 하부금형으로 하우징(1)의 정면(2)과 배면(3)을 형성할 수 있도록 하우징(1)을 눕힌 상태로 성형하여 하우징(1)의 정면(2)이나 배면(3)에 유체의 흐름방향(8)과 제조회사의 이름 및 마크 등을 돌출되게 성형한다.In molding the housing by fixing the mold to the press, the housing 1 is formed by laying the housing 1 in a lying state so that the front mold 2 and the rear mold 3 of the housing 1 can be formed into the upper mold and the lower mold. On the front (2) or back (3) of the), the flow direction of the fluid (8) and the name and mark of the manufacturer are molded to protrude.
상기 상부금형과 하부금형을 동작시킬 때 이와 동시에 정면금형과 배면금형 및 우측금형과 좌측금형 모두가 동시에 동작되는 것으로서, 이때 정면금형과 배면금형에 의해 상부홀(4)과 하부홀(5)이 성형되도록 하고, 우측금형과 좌측금형에 의해 유체의 유입홀(6)과 유출홀(7)이 단조성형되도록 하여서 된 것이다.When the upper mold and the lower mold are operated at the same time, both the front mold and the back mold and the right mold and the left mold are operated at the same time, wherein the upper and lower holes 5 are formed by the front mold and the back mold. The inlet hole 6 and the outlet hole 7 of the fluid are forged by the right mold and the left mold.
이와 같은 본 발명은 하우징(1)을 단조성형할 때 상부금형과 하부금형, 정면금형과 배면금형 및 우측금형과 좌측금형을 단조프레스에 설치하되 하부금형은 하형으로서 고정되게 설치하고 그 외의 상부금형, 정면금형, 배면금형, 우측금형 및 좌측금형은 축방향으로 동시에 이동가능하게 설치하여 소재에 대해 6방향에서 동시에 프레싱하여 목적하는 하우징(1)을 단조성형할 수 있도록 한다.In the present invention, when forging the housing 1, the upper mold and the lower mold, the front mold and the back mold and the right mold and the left mold are installed in the forging press, but the lower mold is fixedly installed as the lower mold and the other upper mold The front mold, the back mold, the right mold and the left mold are installed to be movable simultaneously in the axial direction so that they can be pressed simultaneously in six directions with respect to the material to forge the desired housing 1.
이때, 단조성형되는 하우징(1)은 눕힌 상태로 성형되도록 하는 것이므로 상부금형과 하부금형에 의해서는 하우징(1)의 정면(2)과 배면(3)이 성형될 뿐만 아니라, 이로 인하여 유입홀(6)과 유출홀(7)의 외주면이 각지게 성형되는 것을 방지할 수 있고, 하우징(1)의 정면(2)과 배면에는 유체의 흐름방향(8)을 표시할 수 있게 되는 것이다.At this time, the forging molded housing (1) is to be molded in a lying state because the upper mold and the lower mold not only forms the front (2) and the back (3) of the housing (1), thereby inlet hole ( 6) and the outer circumferential surface of the outlet hole 7 can be prevented from being sharply formed, and the flow direction 8 of the fluid can be displayed on the front surface 2 and the rear surface of the housing 1.
또한, 상기 상부금형 및 하부금형과 함께 동시에 동작되는 정면금형과 배면금형은 하우징(1)의 하부홀(5)과 상부홀(4)을 성형하고, 역시 상기 금형들과 동시에 작동되는 우측금형과 좌측금형은 유체의 유입홀(6)과 유출홀(7)을 성형하게 되므로 단조성형후의 후가공 작업이 간편해지는 것이다.In addition, the front mold and the back mold which is operated simultaneously with the upper mold and the lower mold form the lower hole 5 and the upper hole 4 of the housing 1, and the right mold which is also operated simultaneously with the molds. The left mold is to form the inlet hole (6) and the outlet hole (7) of the fluid is to simplify the post-processing work after forging molding.
한편, 상기와 같이 성형되는 하우징(1)은 모든 성형공정이 동시에 이루어지기 때문에 각각의 공정을 거칠때마다의 소재냉각시간이 불필요하게 되어 그 만큼 작업속도를 단축시키면서 생산성을 증대시킬 수 있을 뿐만 아니라, 제품으로서 감압밸브의 외관미를 향상시킬 수 있게 된다.On the other hand, the housing 1 to be molded as described above because all the molding process is made at the same time, the material cooling time for each step is not necessary, so that the productivity can be increased while reducing the work speed by that much As a product, the appearance of the pressure reducing valve can be improved.
상기에서와 같이 본 발명은 감압밸브의 하우징을 단조성형할 때 동시에 작동되는 상부금형과 하부금형, 정면금형과 배면금형 및 우측금형과 좌측금형에 의해 하우징의 외형, 상부홀과 하부홀, 유입홀과 유출홀을 동시에 성형함으로써 하우징의 표면에 유체의 흐름방향을 표시하면서도 외관미를 향상시킴과 동시에 생산성을 향상시키고 후가공공정을 간편하게 할 수 있는 효과가 제공되는 것이다.As described above, the present invention is characterized in that the upper mold, the lower mold, the front mold and the back mold, and the right mold and the left mold are operated simultaneously when forging the housing of the pressure reducing valve. Simultaneous molding of the outflow hole and the flow direction of the fluid on the surface of the housing while improving the appearance and at the same time improve the productivity and simplify the post-processing process is provided.
