Description
【発明の詳細な説明】 〔発明の属する技術分野〕 この発明は水車用ガイドベーンの製造方法に関する。[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a method for manufacturing guide vanes for water turbines.

鋳造し、これに機械加工。FIG. 1 is an external perspective view of a guide vane for a water turbine, which is composed of a main body 1 and a shaft portion 2. As shown in FIG. The conventional manufacturing method for this type of guide vane is to first integrally cast the main body 1 and the shaft portion 2 at the same time, and then machine them.

表し製作工数が大であるといった問題がある。It was made into a product with a polished finish. However, due to the requirement for anti-cavitation properties on the surface, high-quality materials such as stainless steel were used for the entire casting material, including the interior of the main body and the shaft, which do not require cavitation resistance. Therefore, (a) the material cost is high because it is integrally cast using high-grade materials such as stainless steel, and 6:I) the shape of the wing surface of the main body is complex and an expensive wooden mold is required for casting.
e→As-cast blades have a large blade surface roughness, so at least both the front and back blade surfaces require machining and polishing, resulting in a large number of manufacturing steps.
この発明は上述した欠点匿鑑み、高級材料の使用量を少

を目的とする。In view of the above-mentioned drawbacks, it is an object of the present invention to provide a manufacturing method that reduces the amount of high-grade materials used and reduces manufacturing costs.

However, this is achieved by integrally casting the inner space of the outer shell and the shaft portion at the same time.

個所Ｐ。The manufacturing method according to the present invention will be explained step by step based on the drawings. First, the front wing surface plate 1a of the main body shown in FIG. 2 is formed by sheet metal processing. This material has a thickness of, for example, 7III.
It is a 5US430 plate material of about I11, and requires local bending molds during processing, but it is not expensive. Next, the main body back side wing plate 1b shown in FIG. 3 is formed using the same material as in the case of FIG. 2 and by the same sheet metal processing. These two wing face plates 1a and lb are combined as shown in Fig. 4, and the combined point P is formed.

, lb and the shaft portion 2 are integrally cast using, for example, FOD45. In this case, the part that requires machining or polishing is the welding part P.
Ｑと軸部２のみであり、従来量も工数を必要とした翼面
の加工は不要となり加工工数は低減される。Since only the Q and shaft portion 2 are required, machining of the blade surface, which conventionally required man-hours, is not required, and the number of man-hours for machining is reduced.

体としては従来より概算４１％コスト低減可能である。After forming the shell of the main body into a sheet metal, this can be used as a casting pot, eliminating the need for a wooden mold for casting the inside of the main body, and eliminating the need for polishing, which takes a lot of man-hours, for both surfaces. In terms of materials, only a small amount of high-grade materials are used for both wing plates, and low-grade materials such as FOD45 can be used for the interior and shaft parts, where large amounts of materials are used, so material costs can be significantly reduced. Overall, the cost can be reduced by approximately 41% compared to the conventional method.
