回転させた場合に、該ゲージ４のゲージ面４ａが該端面
２に位置を変えつつ摺接するような形状に切削される。That is, as shown in FIGS. 5 and 6, one end surface 2 is the gauge surface of the gauge 4 when the gauge 4 is rotated about the axis ' corresponding to the axis k of the impeller. 4a is cut into a shape such that it slides into contact with the end face 2 while changing its position.
しかしてこのゲージ４のゲージ面４ａは、羽根のアイ側
端面形状ｉに対応させであるのでつ才り、第２図に示す
成形板ｄの成形面ｄ′と同一の形状に設定しであるので
、前記端面２は羽根のアイ側端面形状ｉに対応する形に
成形される。However, the gauge surface 4a of the lever gauge 4 is designed to correspond to the shape i of the end surface on the eye side of the blade, and is therefore set to have the same shape as the molding surface d' of the molding plate d shown in FIG. Therefore, the end surface 2 is formed into a shape corresponding to the eye-side end surface shape i of the blade.
他方の端面３は第７図、第８図に示すように、ゲ゛−ジ
５を前記軸に′を中心に回転させた場合に、該ゲージ５
のゲージ面５ａが、該端面３に位置を変えつ５摺接する
ような形状に切削される。As shown in FIGS. 7 and 8, the other end surface 3 is shaped like the gauge 5 when the gauge 5 is rotated about the axis
The gauge surface 5a is cut into a shape such that it slides into contact with the end surface 3 at different positions.
しかして、このゲ゛−ジ５のゲ゛−ジ面５ａは、羽根の
ボス側端面形状ｊに対応させであるので、つまり、第１
図に示す木型すの成形面ｂ′と同一の形状に設定しであ
るので、前記端面３は、羽根のボス側端面形状ｊに対応
する形に成形される。Since the gauge surface 5a of this gauge 5 corresponds to the boss side end surface shape j of the blade, that is, the first
Since it is set to have the same shape as the molding surface b' of the wooden mold shown in the figure, the end surface 3 is molded into a shape corresponding to the boss side end surface shape j of the blade.
次いで、この素材１から不必要な部分（第５図に斜線で
示す部分以外の部分）を切削する。Next, unnecessary parts (other than the shaded parts in FIG. 5) are cut from this material 1.
つまり予め設計された羽根模型１枚分（第１２図で示す
羽根模型８の分）が得られるように、前記素材１から適
宜必要な部分（第５図で示す斜線の部分）をノコギリ等
で切除する。In other words, in order to obtain one pre-designed blade model (the part for blade model 8 shown in Figure 12), appropriate necessary parts (shaded areas shown in Figure 5) are cut from the material 1 using a saw etc. Excise.
次に、この切除された素材１に第９図乃至第１１図で示
すゲージ１を用いて切削した場合に、該素材１から第１
２図で示す羽根模型８の流水面８ａが得られるように、
該素材１を前記ゲージ７に対して適宜位置を設定する。Next, when the cut material 1 is cut using the gauge 1 shown in FIGS. 9 to 11, a first
In order to obtain the flowing water surface 8a of the blade model 8 shown in Figure 2,
The material 1 is appropriately positioned with respect to the gauge 7.
そして、この素材１の一端面２から他端面３に亘る部位
Ｈに、その他端面３から一端面２に向けて下方に傾斜す

て形成する。Then, an arc-shaped rotating surface 6 that slopes downward from the other end surface 3 toward the one end surface 2 is formed by manual finishing using a gauge 7 at a portion H extending from one end surface 2 to the other end surface 3 of this material 1. .
つまり、回転面６は、第９図、第１０図に示すようにゲ
ージ１を前述した抜き中心ｅに相当する軸ｅ′を中心に
回転させた場合に、該ゲニン７のゲージ面７ａが、該回
転面６に位置を変えつＳ摺接するような形状に切削され
る。That is, when the rotating surface 6 rotates the gauge 1 around the axis e' corresponding to the above-mentioned punching center e as shown in FIGS. 9 and 10, the gauge surface 7a of the genin 7 becomes It is cut into a shape that makes sliding contact with the rotating surface 6 while changing its position.
しかして、このゲージＴのゲージ面７ａは羽根の流水面
を抜き中心ｅを含む平面で切断した場合の断面形状に対
応する形状に設定しであるので、前記回転面６は羽根の
流水面形状に相当する曲面形状に形成される。Since the gauge surface 7a of the gauge T is set to a shape corresponding to the cross-sectional shape when the water surface of the blade is cut along a plane including the center e, the rotating surface 6 has the shape of the water surface of the blade. It is formed into a curved shape corresponding to .
次いで、この素材１の反回転面６側を前記回転面６に沿
って、かつこの回転面６との間に所定の肉厚を残して切
削することによって、前記回転面６を流水面８ａとする
羽根模型８′ｔ−得る。Next, by cutting the anti-rotation surface 6 side of this material 1 along the rotation surface 6 and leaving a predetermined thickness between the rotation surface 6 and the rotation surface 6, the rotation surface 6 is turned into a flowing water surface 8a. Obtain a blade model 8't-.
このような製造方法において、特に本発明では、素材１

ので、点の座標を追いつ＼流水面を形成する場合に比べ
て、流水面８ａ全体を円滑でしかも正確な形状に形成す
ることができる。In such a manufacturing method, especially in the present invention, the material 1
Since the rotating surface 6 is formed using the gauge 7 and the blade model 8 is formed using the rotating surface 6 as the flowing water surface 8a, it is easier to follow the coordinates of the points than when forming the flowing water surface. Thus, the entire flowing water surface 8a can be formed into a smooth and accurate shape.
したがって、ポンプ性能の安定化を図ることができると
いう利点がある。Therefore, there is an advantage that the pump performance can be stabilized.
