号）。[Prior Art] Conventionally, when the vehicle wheel W is formed by spinning, as shown in FIG. 2, the disk material D and the rim material cylinder 3 are formed by forging or casting to obtain the wheel material 1.
Then, the rim portion 31 was formed by squeezing the material 1 onto the rim forming mandrel 4 in the direction of the arrow by the rotary pressing tool 5 (Japanese Patent Laid-Open No. 61-115640).

生じる海面状又は多孔質の巣のことである。However, in such a conventional spinning forming method, since the wall thickness of the connecting portion between the rim material cylinder 3 and the disk portion D is large, when the material 1 is cast, the connecting portion 311 is eccentric. However, there is a problem in that it is difficult to maintain the strength of the vehicle wheel to be formed by spinning. Here, "kusare" is a field term for a nest, and in many cases air penetrates into the nest, causing rusting and coloring, and the state becomes something like a rotting substance. In addition, a "plow nest" is a sea surface-like or porous nest formed in the final solidified portion of the molten metal.
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.

外壁面に周溝状のくびれを形成したものである。In order to solve the above-mentioned problems, in the spinning molding material for a vehicle wheel of the present invention, a rim material cylinder is integrally formed on the peripheral edge of the disc portion, and the rim material cylinder is externally fitted to the molding mandrel. In a vehicle wheel spinning molding material for molding a vehicle wheel by spinning molding, a peripheral groove-shaped constriction is formed on an outer wall surface of a substantially continuous portion of the rim material cylinder and the disk portion. is there.

部にクサレは生じにくいものである。Since the spinning molding material for a vehicle wheel according to the present invention is configured as described above, that is, a circumferential groove-shaped constriction is formed on the outer wall surface of the substantially continuous portion of the rim material cylinder and the disc portion. Therefore, as a result that the connecting portion between the rim material cylinder and the disk portion can be made thin, it is difficult for the connecting portion to be eccentric when casting such a vehicle material.
以下図面に基づいてこの発明の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.

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. Reference numeral 312 denotes a constriction, which is formed on the outer wall surface of the continuous portion of the rear rim material cylinder 3 and the disc portion D. This constriction 31
2 extends in a groove shape over the peripheral surface of the back side rim material tube 3.

ィスク部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 formed by the back side rim material tube 3 and the rim forming surface 41 is preferably about 8 degrees. . Further, the peripheral portion 32 of the rim material cylinder 3 has a larger diameter in the radial direction of the disc portion D than the rim flange molding surface 42 of the mandrel 4.

ものである。Then, by rotating the mandrel 4 around the axis 43 and squeezing the back side rim material tube 3 in the direction of the arrow by the rotary pressing tool 5, the material tube 3 is sequentially deformed into a virtual line (from right side to left side). Then, the rear rim 31 and thus the vehicle wheel W are molded. In this case, since the constriction 312 is formed on the outer wall surface of the back side rim material tube 3, the spinning operation can be speeded up and the material yield can be improved.
なお、６はホイール素材１をマンドレル４に挟持固定す

部にクサレは生じにくいものである。In the spinning forming material for a vehicle wheel according to the present invention, a rim material cylinder is integrally formed on the peripheral edge of the disc portion, and the rim material cylinder is externally fitted to the molding mandrel to perform spin molding. In the spinning molding material for a vehicle wheel for molding a wheel for a vehicle, since a circumferential groove-shaped constriction is formed on the outer wall surface in the substantially continuous portion of the rim material cylinder and the disk portion, the rim material cylinder and the disk portion are formed. As a result of making the connecting portion thin, it is difficult for the connecting portion to be eccentric when casting such a vehicle material.
