【発明の詳細な説明】 〔産業上の利用分野〕 この発明は車両用ホイールのスピニング成形方法に関
し、特に、リム部をスピニング成形によって形成するも
のである。Description: TECHNICAL FIELD The present invention relates to a vehicle wheel spinning forming method, and more particularly, to forming a rim portion by spinning forming.
従来において、車両用ホイールＷをスピニング成形する
場合、第２図に示すように、ディスク部Ｄ及びリム素材
筒３を鍛造又は鋳造で形成してホイール素材１を得る。
そして、この素材１をリム成形用マンドレル４に外嵌め
した状態で回転押圧具５で矢印方向にしごくことにより
リム部31を形成していた（特開昭61−115640号）。Conventionally, when the vehicle wheel W is formed by spinning, the wheel material 1 is obtained by forming the disc portion D and the rim material cylinder 3 by forging or casting, as shown in FIG.
Then, the rim portion 31 was formed by squeezing the material 1 onto the rim forming mandrel 4 in the direction of the arrow with the rotary pressing tool 5 (JP-A-61-115640).
しかしながら、かかる従来のスピニング成形法にあって

際に、このリム素材筒３を前記リム成形用マンドレル４
の成形面41に密着させていた。However, in such a conventional spinning molding method, when the rim material cylinder 3 is installed on the rim molding mandrel 4, the rim material cylinder 3 is mounted on the rim molding mandrel 4.
It was in close contact with the molding surface 41 of.
このため、回転押圧具５でかかる素材筒３をしごく際
に、素材筒３とマンドレル４の成形面41との間に摩擦が
生じ、この結果、素材筒３を成形面41のリムフランジ成
形部に沿ってしごくに手間がかかるという不都合を有し
た。Therefore, when the material cylinder 3 is squeezed by the rotary pressing tool 5, friction occurs between the material cylinder 3 and the molding surface 41 of the mandrel 4, and as a result, the material cylinder 3 is rim flange molding part of the molding surface 41. There was an inconvenience that it took a lot of time to squeeze along.
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.

径とし、且つ、前記リム素材筒における周縁部の肉厚を
その根幹部の肉厚よりも大としたものである。In order to solve the above problems, in the vehicle wheel spinning forming method according to the present invention, a rim material cylinder is integrally formed on the peripheral edge of the disk portion, and the rim material cylinder is externally fitted to the rim forming mandrel. In a vehicle wheel spinning molding method for molding a rim portion by spinning molding in a state, when installing the rim material cylinder on the molding mandrel,
The peripheral portion of the rim material cylinder has a larger diameter in the radial direction of the disc portion than the rim flange molding portion of the molding mandrel, and the thickness of the peripheral portion of the rim material cylinder is the thickness of its root portion. Bigger than that.

以て作業をすることができる。Since the vehicle wheel spinning molding method according to the present invention is configured as described above, the rim material tube is squeezed along the rim flange molding portion when the rim material tube is squeezed along the molding surface of the mandrel. Also, because the wall thickness of the peripheral portion of the rim material cylinder is made larger than the wall thickness of the root portion, there is a margin to work on the material when squeezing the rim material cylinder along the rim flange forming part of the mandrel. You can
以下、この発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

なる。In FIG. 1, D is a disc portion of the vehicle wheel material 1, and 2 is a front rim portion integrally formed on the front peripheral edge of the disc portion D by forging or casting. Reference numeral 3 denotes a back side rim material tube (corresponding to the "rim material tube" of the present invention), which is integrally formed on the back side peripheral edge of the disc portion D by forging or casting like the front side rim portion 2. The back side rim material tube 3 becomes the back side rim portion 31 by spinning molding.

スク部Ｄの半径方向に大径である。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. . Also, the tip 32 of the rim material tube 3
Has a larger diameter in the radial direction of the disk portion D than the rim flange forming surface 42 of the mandrel 4.

に当該素材に余裕を以て作業をすることができる。The spinning molding method for a vehicle wheel according to the present invention comprises integrally forming a rim material cylinder on a peripheral edge of a disc portion, and performing spin molding while the rim material cylinder is externally fitted to a rim molding mandrel. In the method of spinning forming a vehicle wheel for forming, when installing the rim material tube on the forming mandrel,
The peripheral portion of the rim material cylinder has a larger diameter in the radial direction of the disc portion than the rim flange molding portion of the molding mandrel, and the thickness of the peripheral portion of the rim material cylinder is the thickness of its root portion. Since it is larger than the rim material cylinder, it is easy to fit the rim material cylinder along the rim flange molding part when squeezing the rim material cylinder along the molding surface of the mandrel. Since the thickness is made larger than the thickness of the root portion, the material can be worked with a margin when the rim material tube is squeezed along the rim flange forming portion of the mandrel.
