Description

볼밸브용 보올 제조방법Ball Valve Manufacturing Method

제1도는 본 발명의 완성된 보올의 사시도.1 is a perspective view of a completed bowl of the present invention.

제2도는 제1도의 종단면도.2 is a longitudinal cross-sectional view of FIG.

제3도는 본 발명의 실시예 시도로서 보올의 제조과정도.3 is a manufacturing process of the bowl as an embodiment of the present invention.

본 발명은 볼 밸브의 관접부 또는 아답터의 관접부에 삽착되어지는 패킹과 유통공이 천설된 보올을 제조함에 있어서 동합금(銅合金)으로 된 관체를 보올로 성혈할 수 있도록 적당한 길이로 절단하여 소재로 하고 이 소재가 적열 상태가 되도록 가열한 다음 펀치 프레스로 가압 성형하여 소망하는 크기의 볼 뱀브용 보올을 제조하는 방법에 관한 것이다.The present invention is made by cutting a pipe body made of copper alloy into a length suitable for making a blood-filled body in the manufacture of a bowl in which a packing and a distribution hole inserted into a pipe portion of a ball valve or a pipe portion of an adapter are installed. The present invention relates to a method for producing a ball snake ball of a desired size by heating the material so that it is in a red state and then press molding the punch press.

종래의 볼 밸브용 보올의 대표적인 제조방법으로서는 사형(砂型)으로 일단 보올형 주물을 주괴(鑄傀)하여 이를 밸브체의 시트링에 균일하게 습찰되도록 선반 가공과 표면 연마한 후 유통공 및 축수공을 천설하였으므로 이와같이 주물로 주괴하여서 된 보울은 보울의 지금이 200mm초과하게 되면 제작상 난점이 야기될 뿐 아니라 핀홍(pin hole)이나 주물의 수축시 방생하는 균열 등으로 인한 불량주괴의 파기 처분으로 제품의 허실이 많았고 제작공정이 비능률적이어서 제품가의 저하를 기하기가 어려웠다.A typical manufacturing method of the ball valve bowl is a sand mold, and once the ball-type casting is ingot, the lathe processing and the surface polishing are performed so that it is uniformly observed in the seating of the valve body. Since it was insulated from casting, the bowl made by casting in this way will not only cause difficulties in manufacturing if the bowl is over 200mm now, but also by discarding the defective ingot due to pin hole or cracks generated during shrinkage of the casting. It was difficult to reduce the price of the product due to a lot of false positives and inefficient manufacturing process.

본 발명은 이와같은 방법에 의하지 않고 동합금으로 된 관체를 보올을 성형할수 있도록 적당한 길이로 절단하여 소재로 하고 이 소재를 500℃ 정도로 가열하여 적열상태가 되도록 한 다음 이를 펀치 프레스로서 30ton 정도의 압력으로 가압 성형하게 되면 소재의 관공이 유통공으로 되는 보올이 성형되어지며 이후 표면 연마 및 축수공의 드릴 공정만 거치게 되면 완전한 볼 밸브용 보올이 제작되어지는 것으로 생산성을 높이고 불량품의 발생을 극소화하는 동시에 작업이 용이할 뿐 아니라 경제적으로 양산할 수 있어 획기적인 원가절감을 기할 수 있게 한 것이다.According to the present invention, the copper alloy tube body is cut to a suitable length so as to form a bowl, and the material is heated to about 500 ° C. to be in a red state. When pressure molding is used, a bowl is formed in which a pipe is a distribution hole, and after the surface grinding and drilling process is completed, a complete ball valve bowl is produced, which increases productivity and minimizes the occurrence of defective products. It is not only easy but also economically mass-produced, so that it is possible to drastically reduce cost.

이에 첨부된 실시예도에 의하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제3도에 도시된 (a)와 같은 관공(5')이 길이방향으로 상통하는 동합금(銅合金)으로 된 관체(5)를 볼 밸브용 보올(1)로 성형할 수 있도록 (b)도에 도시한 바와 같이 적당한 길이로 절단하여 소재 (a)로 하고 이 소재(a)를 (c)와 같이 500℃ 정도로 가열하여 적열상태가 되도록 가열한 다음 (d)도에 도시한 바와 같이 펀치 프레스(3)로서 30ton 정도의 프레스 압력으로 가압 성형하게 되면 (e)와 같이 소재 (a)의 관공(5')이 통수공(3)으로 되는 보올(1)이 일체로 성형되어지는 것이다.(B) so that the tubular body 5 made of copper alloy in which the tubing 5 'such as (a) shown in FIG. 3 is in the longitudinal direction can be formed into the ball valve bowl 1 As shown in Fig. 1, the substrate is cut into a suitable length to be a raw material (a). The raw material (a) is heated to about 500 ° C. as shown in (c), and heated to a red state. Then, as shown in (d), the punch press is shown. When (3) is press-molded at a press pressure of about 30 tons, as shown in (e), the bowl 1 in which the hole 5 'of the raw material (a) becomes the water hole 3 is integrally molded.

그리고 소재를 적열상태로 가열시킬 때의 온도가 500℃ 정도일 때가 가장 적당하나 그 이상 및 이하의 근사치 범위내의 온도에서는 온도 정도에 맞추어 프레스 압력을 증감하므로서 같은 효과를 가질 수 있다.And when the temperature of the material is heated to a red state is most suitable when the temperature is about 500 ℃, the temperature within the above and below the approximate range can have the same effect by increasing or decreasing the press pressure in accordance with the temperature degree.

이와같이 성형되어진 보올(1)은 표면연마 및 축수공(2')의 드릴 공정만 거치며는 완전한 볼 밸브용 보올이 제작되어진다.The molded bowl 1 is made of a complete ball valve bowl only through the surface grinding and drilling process of the bearing 2 '.

본 발명에 있어 보올체가 되는 외주 표면은 통상의 펀치 프레스에서 성형되어지는 제품의 표면과 마찬가지로 금형 표면과 같이 정밀하고 깨끗하여 주물로 성형되는 보올형의 주괴와는 달리 선반가공이 불필요하며 보올형의 주괴에서 볼 수 있는 것처럼 용량의 냉각으로 인한 응고후 주물의 균열이나 수축공이 조성되어진 불량주괴로 인한 소재의 허실을 일체 배제하였을 뿐 아니라 절단된 관체소재의 외주벽이 펀치 프레스의 금형에 의하여 압형되어 보울의 구면벽으로 성형되었으므로 후육부가 없어서 재질의 낭비가 없으며 주괴로 된 종래의 보울에 비하여 내마도성이 크고 또한 내구력 및 지지보강력이 우수하다.In the present invention, the outer circumferential surface to be a ball body, like the surface of a product to be molded in a conventional punch press, is precise and clean like the mold surface, unlike the ingot of the ball type that is molded into a casting, the lathe processing is unnecessary and As can be seen from the ingots, not only does it eliminate the loss of the material due to the defective ingots formed by cracking or shrinkage of the casting after solidification due to the cooling of the capacity, but also the outer peripheral wall of the cut tubular material is pressed by the mold of the punch press. Since it is molded into the spherical wall of the bowl, there is no thick part, so there is no waste of material, and the wear resistance is large and the durability and supporting reinforcement are superior to the conventional bowl made of ingot.

이상과 같은 본 발명은 제작공정의 간편성, 불량품 발생의 최소화 및 정교한 제품 생산에 있어 능률의 극대화로 인한 양산첵제 등의 획기적인 원가절감 효과를 갖는 특징이 있다.The present invention as described above is characterized by having a significant cost-cutting effect, such as mass production agents due to the simplicity of the manufacturing process, minimizing the occurrence of defective products and maximizing efficiency in producing sophisticated products.
