徴とするものである。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention rolls a rectangular rolled plate into a ring shape and butt-welds the butt parts, and then In a method in which a hoop material is formed by removing burrs, and then the hoop material is roll-formed into a predetermined shape, the hoop material is formed into a predetermined shape by a roll such as spinning between the burr removal step and the roll-forming step. It is characterized by the addition of a process of thinning the part.
次に本発明の製造方法を図面に基づいて説明する。 Next, the manufacturing method of the present invention will be explained based on the drawings.
先ず、第１図に示すようなスチールまたはアルミニウム
合金等の軽合金からなる所定の矩形の圧延板１を用意す
る。 次で該圧延板１を第２図に示すようにリング状に
巻いてその両端１ａ、 ｌｂを突き合せ、該突き合せ部
を溶接した後、該溶接部のバリを切削除去して第２図に
示すようなフープ材２を成形する。 次で、前記フープ
材２を、第３図に示すようにマンドレル３にセットし、
スピニングなどのロール４によって、所定部位を薄肉化
する。 本実施例では、フランジ部に相当する部分２ａ
、 ２ｂ以外の部分、すなわち、第５図に示すビードシ
ート部５ｃ＋ ウェルコーナ５ｄ、 ウェル部５ｅ
に相当する部分Ａを薄肉化している。 次で、前記のよ
うに成形された不等肉厚のフープ材２ｃを、ロール成形

５ｂが厚肉に、その他のビードシート部５ ｃ ＋ ウ
ェルコーナ部５ｄ、 ウェル部５ｅが薄肉になった最終
仕上りのリム５が得られる。First, a predetermined rectangular rolled plate 1 made of steel or a light alloy such as an aluminum alloy is prepared as shown in FIG. Next, the rolled plate 1 is rolled into a ring shape as shown in FIG. 2, and the two ends 1a and lb are butted together, and the abutted portions are welded.The burrs at the welded portions are then cut off and the welded portions are removed. A hoop material 2 as shown in is molded. Next, the hoop material 2 is set on a mandrel 3 as shown in FIG.
A predetermined portion is thinned by a roll 4 such as spinning. In this embodiment, a portion 2a corresponding to the flange portion
, parts other than 2b, that is, the bead seat portion 5c+ shown in FIG. 5, the well corner 5d, and the well portion 5e.
Portion A corresponding to , is made thinner. Next, the hoop material 2c of unequal thickness formed as described above is roll-formed to form a final finished rim which is bent in a predetermined manner as shown in FIG. By this molding, the flange portion 5a,
A final finished rim 5 is obtained in which the bead seat portion 5b is thick and the other bead seat portions 5c + well corner portions 5d and well portions 5e are thin.
前記実施例においては、フランジ部５ａ、 ｓｂ基以外
部分の肉厚を薄くシた場合を示したが、各部位の肉厚は
、その部位の必要剛性に対応して所望に設定される。
例えば、フランジ部５ａ、 ５ｂとウェルコーナ５ｄに
大きな剛性が要求され、その他の部分の剛性は小さくて
よい場合は、フランジ部５ａ＋５ｂとウェルコーナ部５
ｄの肉厚を厚くしてその他の部分はロール４により肉厚
を薄くする。In the embodiment described above, the wall thickness of the portions other than the flange portion 5a and the sb group is made thin, but the wall thickness of each portion is set as desired in accordance with the required rigidity of that portion.
For example, if large rigidity is required for the flange portions 5a, 5b and the well corner 5d, and low rigidity is required for other parts, the flange portions 5a+5b and the well corner 5d may be
The wall thickness of d is made thicker, and the other parts are made thinner by the roll 4.
本発明のホイール用リムの製造方法によれば、大きな剛
性を必要とする部位の肉厚を厚（し、小さな剛性でよい
部位の肉厚を薄くして、ぜい肉を除去した不等肉厚のリ
ムを成形できるため、前記従来のようにリム全体を厚肉
に成形するものに比べて、最終仕上りのリムの重量を軽
量化できる。According to the method for manufacturing a wheel rim of the present invention, the wall thickness is increased in areas that require large rigidity, and the wall thickness is reduced in areas that require small rigidity, thereby creating a rim with unequal thickness that eliminates flab. Since the rim can be molded, the weight of the final rim can be reduced compared to the conventional method in which the entire rim is molded thickly.
しかも、その薄肉化を、溶接バリ除去工程とロール成形
工程との間において、スピニングなどのロールによって
行なうようにしたので、その薄肉化作業が容易に行なえ
る。In addition, since the thinning is performed using a spinning roll or the like between the welding burr removal process and the roll forming process, the thinning process can be easily performed.
