本発明”は円筒状多翼ファンの製作方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a cylindrical multi-blade fan.
従来一般の多翼ファンは、翼を一本一本製作し、この翼
を円板に植えることにより製作されていた。Conventionally, general multi-blade fans have been manufactured by manufacturing individual blades one by one and planting these blades on a disk.
この製作方法によれば、翼の製作および固定などに多く
の工数を要していた。According to this manufacturing method, many man-hours are required for manufacturing and fixing the wings.
そこで、金属製円板素材よりその円板面と直角方向に翼
を多数等間隔に、温間または冷間で押出し成形すること
が試みられたが、薄い翼を押出す場合に大きな押出力が
必要となり、型の破損を招いて経済的でなかった。Therefore, an attempt was made to extrude a large number of blades from a metal disk material at regular intervals in the direction perpendicular to the disk surface, either warm or cold, but when extruding thin blades, a large extrusion force was required. This was not economical as it caused damage to the mold.
また、長い翼を押出し成形することが困難であった。Also, it was difficult to extrude long wings.
本発明はかかる欠陥を解消せんとしてなされたものであ
る。The present invention has been made in an attempt to eliminate such deficiencies.
即ち、金属製円板素材１よりその円板面と直角方向に翼
゛６を多数等間隔に温間または冷間で押出し成形してな
る円筒状多翼フーアンの製作方法において、前記円板素
材１をリング状としその内径と外径との比を０．７以上
とし、更に前記翼６の外径を前記円板素材１の外径と一
致させ、且つ前記翼６の内径゛を前記円板素材１の内径
と一致させたものである。That is, in the manufacturing method of a cylindrical multi-blade foun, in which a large number of blades 6 are extruded from a metal disk material 1 in a direction perpendicular to the disk surface at equal intervals in a warm or cold manner, the disk material 1 is 1 is ring-shaped, and the ratio of its inner diameter to outer diameter is 0.7 or more, and the outer diameter of the blade 6 is made to match the outer diameter of the disc material 1, and the inner diameter of the blade 6 is set to be equal to the circular diameter. This is made to match the inner diameter of the plate material 1.
以下、本発明の詳細を第１図〜第３図に示す一実施例に
基づいて説明する。Hereinafter, details of the present invention will be explained based on an embodiment shown in FIGS. 1 to 3.
金属製円板素材１は第１図に示す如くリング状に製作す
る。The metal disk material 1 is manufactured into a ring shape as shown in FIG.
この円板素材１の内径３と外径２との比を０．７以上と
し、０．９５程度までが適当である。The ratio of the inner diameter 3 to the outer diameter 2 of this disc material 1 is set to be 0.7 or more, preferably up to about 0.95.
次いで、第２図に示す如くこの円板素材１よりその円板
面と直角方向に翼６を多数等間隔に押出し成形する。Next, as shown in FIG. 2, a large number of blades 6 are extruded from this disc material 1 at equal intervals in a direction perpendicular to the disc surface.
この場合、翼６の外径４および内径５を円板素材１の外
径２および内径３と一致させておく。In this case, the outer diameter 4 and inner diameter 5 of the blade 6 are made to match the outer diameter 2 and inner diameter 3 of the disc material 1.
この翼′６の押出し成形を第３図により詳述する補強リ
ング１で囲まれたダイス８にリング状溝９を設けている
。The extrusion molding of this wing '6 will be explained in detail with reference to FIG. 3. A ring-shaped groove 9 is provided in a die 8 surrounded by a reinforcing ring 1.
このリング状溝９の下面には翼６を成形するに必要なダ
イス穴１２を設けている。A die hole 12 necessary for molding the blade 6 is provided on the lower surface of the ring-shaped groove 9.
このダイス穴１２は翼６の断面形状と同じであり、必要
個数、等間隔に設けられている。The die holes 12 have the same cross-sectional shape as the blade 6, and are provided in a required number at equal intervals.
このダイス穴１２の内径および外径はリング状溝９の内
径および外径と一致している。The inner and outer diameters of this die hole 12 match the inner and outer diameters of the ring-shaped groove 9.
又、このダイス穴１２の下部には逃げ部１３を設けてい
る。Further, a relief part 13 is provided at the lower part of the die hole 12.
リング状溝９の上方には上下動するポンチ１４を有して
いる。A punch 14 that moves up and down is provided above the ring-shaped groove 9.
而して、溝９内に円板素材１を入れ、ポンチ１４を下降
して素材１を加圧すると、溝９内に充満している索材１
はその円周方向に流動してダイス穴１２より押出される
。Then, when the disk material 1 is put into the groove 9 and the punch 14 is lowered to pressurize the material 1, the cable material 1 filling the groove 9 is removed.
flows in the circumferential direction and is extruded from the die hole 12.
かかる製作方法によれば、素材１は内径′３と外径２と
の比が０．７以上のリング状に成形しているので、円周
方向に材料が流動する際に、移動距離にあまり差が出な
い。According to this manufacturing method, the material 1 is formed into a ring shape with a ratio of the inner diameter '3 to the outer diameter 2 of 0.7 or more, so when the material flows in the circumferential direction, there is little difference in the moving distance. There is no difference.
これによって、円周方向にスムースに材料を流動するこ
とができるので、小さな押出し力で成形することができ
る。This allows the material to flow smoothly in the circumferential direction, so that molding can be performed with a small extrusion force.
又、翼６の外径４および内径５を円板素材１の外径２お
よび内径３とを一致させているので、円板素材１は円周
方向の流れが主体となり、半径方向の流れがなくなる。In addition, since the outer diameter 4 and inner diameter 5 of the blade 6 are made to match the outer diameter 2 and inner diameter 3 of the disc material 1, the flow in the disc material 1 is mainly in the circumferential direction, and the flow in the radial direction is It disappears.
これによって、材料の流れは円周方向から直角方向へ転
ずるのみとなり、この点からも小さな押出し力で成形で
きる効果を有す。As a result, the flow of the material only shifts from the circumferential direction to the perpendicular direction, and from this point as well, there is an effect that molding can be performed with a small extrusion force.
