号）。Conventionally, for example, when the vehicle wheel W is formed by spinning, as shown in FIG. 2, the disk portion D and the rim material cylinder 3 are formed by forging or casting, and the wheel material 1 is formed.
To get Then, this material 1 is used as a rim forming mandrel 4
The rim portion 31 was formed by squeezing it in the direction of the arrow with the rotary pressing tool 5 in a state of being fitted on the outside (JP-A-61-115640).
issue).
しかしながら、かかる従来のスピニング成形法にあって

かる素材筒３を成形面41の凸部（リムフランジ成形部）
に沿ってしごく場合、立ち上がり部311の肉厚を厚く形
成しにくいという不都合を有した。However, in such a conventional spinning molding method, the material cylinder (rim material cylinder) 3 gradually becomes thinner as it goes to the peripheral edge portion, so that the material cylinder 3 is formed on the molding surface 41 by the rotary pressing tool 5. Convex part (rim flange forming part)
In the case of squeezing along the edges, there is a disadvantage that it is difficult to form the rising portion 311 thickly.
この発明の課題はかかる不都合を解決することである。An object of the present invention is to solve such an inconvenience.
前記課題を解決するために、この発明のスピニング成形

よりも大としたものである。In order to solve the above-mentioned problems, in the spinning forming method of the present invention, the material cylinder to be molded is integrally formed on the peripheral edge of the plate to be clamped, and the material cylinder is externally fitted to the molding mandrel. In the spinning molding method of forming into a predetermined shape by spinning, the wall thickness of the peripheral edge portion of the material tube to be molded is made larger than the wall thickness of the root portion.
この発明に係るスピニング成形方法は、上記のように構

形面に沿ってしごく際に、素材に余裕を以て作業するこ
とができるものである。Since the spinning molding method according to the present invention is configured as described above, when the material tube to be molded is squeezed along the convex molding surface of the mandrel, the material can be worked with a margin.
この発明の実施例として車両用ホイールの製造法を採り
上げ、以下図面に基づいて説明する。A method for manufacturing a vehicle wheel will be taken as an embodiment of the present invention, and will be described below with reference to the drawings.
第１図において、Ｄは車両用ホイール素材１のディスク

又は鋳造によって一体形成されている。この裏側リム素
材筒３はスピニング成形によって裏側リム部31となるも
のであり、周縁部32の肉厚Ａは根幹部の肉厚Ｂよりも大
である。In FIG. 1, D is a disc portion of a vehicle wheel material 1 (corresponding to the “sandwiched plate portion” of the present invention), and 2 is integrally formed on the front peripheral edge of the disc portion D by forging or casting. It is the front rim part. 3 is a back side rim material tube (corresponding to the “molded material tube” of the present invention),
Like the front side rim portion 2, the disk portion D is integrally formed on the back side peripheral edge by forging or casting. The back side rim material cylinder 3 becomes the back side rim portion 31 by spinning molding, and the wall thickness A of the peripheral edge portion 32 is larger than the wall thickness B of the root portion.
このように構成される車両用ホイール素材１をマンドレ

度θは約８度が望ましい。又、リム素材筒３の周縁部32
はマンドレル４のリムフランジ成形面（この発明の「最
高凸部」に相当する。）42よりも突出している（ディス
ク部Ｄの半径方向に）。The vehicle wheel material 1 thus configured is installed on the mandrel 4. In this case, a gap S is formed between the back side rim material tube 3 and the rim forming surface 41 of the mandrel 4, and the angle θ between the back side rim material tube 3 and the rim forming surface 41 is preferably about 8 degrees. . In addition, the peripheral portion 32 of the rim material cylinder 3
Is projected from the rim flange molding surface (corresponding to the "highest convex portion" of the present invention) 42 of the mandrel 4 (in the radial direction of the disc portion D).

（右側から左側に）、立ち上がり部（裏側リム部３の）
311の肉厚を所定の厚さに維持した状態で、裏側リム31
ひいては車両用ホイールＷを成形する。Then, by rotating the mandrel 4 around the axis 43 and squeezing the rear rim material cylinder 3 in the direction of the arrow with the rotary pressing tool 5, the material cylinder 3 is sequentially deformed into a virtual line (from right to left). 2), rising part (of the back side rim part 3)
With the wall thickness of 311 maintained at the specified thickness, back rim 31
As a result, the vehicle wheel W is formed.
なお、６はホイール素材１をマンドレル４に挟持固定す
