本発明はアルミニウム合金またはマグネシウム合金製の
車輌用ホイールの中間形状物を＃ｐＩ造し。[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention manufactures an intermediate shaped article for a vehicle wheel made of an aluminum alloy or a magnesium alloy.
これを’Ｐｙ’ｌから外し、切削加工して完成品とする
鋳造製造法によって製造する車輌用ホイールの、鋳造時

。The present invention relates to the shape of a cast product in an as-cast state during casting, of a vehicle wheel manufactured by a casting manufacturing method in which the wheel is removed from the 'Py'l and cut into a finished product.
（従来の技術）
最近、車輌用ホイールは、その軽量性、耐久性および装
着時の外観美麗性の点からアルミニウム合金製の重輪用
ホイールが広く汗及している。(Prior Art) Recently, heavy-duty wheels made of aluminum alloy have been widely used as vehicle wheels because of their light weight, durability, and beautiful appearance when installed.

成形し、後に切削加工して完成品とするものもある。Some of these aluminum alloy vehicle wheels are manufactured by bending and forming a rolled aluminum alloy plate material, and others are manufactured by tj9 molding of an aluminum alloy material. Furthermore, some products are molded using #PF construction and then cut into finished products.

Figure 2 of the publication (Figure 2 of this specification), or Figure 1 of Utility Model Application Publication No. 59-83102 (Figure 3 of this specification)
A product with the shape described in is cast, and this is yj
It is removed from the mold and the parts that require 1-dimensional accuracy are machined to create a finished product.
（発明が解決しようとする問題点）
例えば、最近の車輌のＦＦ化により、車輌の王な機構が
車輌の前部に集中して塔載されるので。(Problems to be Solved by the Invention) For example, with the recent adoption of front-wheel drive vehicles, key mechanisms of the vehicle are concentrated and mounted on the front of the vehicle.
車輌の前部の必要容積が増加するから、この容積を収容
するため車輪のディスクブレーキ等は車輪側に張出るよ
うに設計しなければならなくなる。Since the required volume at the front of the vehicle increases, wheel disc brakes and the like must be designed to protrude toward the wheels in order to accommodate this volume.
また、ＦＲ車においてもディスクブレーキの冷却のため
の空冷装置の容積が太きくなってきているので、ＦＦ車
と同様にホイールディスク部が張出す設計になってきて
いる。Also, in FR vehicles, the volume of the air cooling device for cooling the disc brakes has become larger, so the wheel disc portions are designed to protrude in the same way as in FF vehicles.
その結果、車輌用ホイールのデザイン面は外方に張り出
し、ホイールのフランジ外側線よりも外側に張出るよう
になる。As a result, the design surface of the vehicle wheel protrudes outward, beyond the outer flange line of the wheel.
このような形状のホイールを鋳造し、＃ｐＪ型から型外

にしてＰＰｆｆ１から落下させると、デザイン面が受は
台に衝突して複雑な立体的意匠のデザイン面に打痕を付
けることがあり、このようにしてデザイン面に傷を生じ
た製品は商品とならなくなる。When a wheel with this shape is cast and removed from the #pJ mold, the design side must be at the bottom due to the casting method of the cast product, and as a result, it is dropped from PPff1 with the design side facing down. When this happens, the design surface collides with the stand and may cause dents on the design surface of the complex three-dimensional design, and products with such scratches on the design surface are no longer commercially available.
このようなことから、デザイン面に打痕を付けないよう
な受は台を用いるか、ｙ！１外し鋳造品の落下衝撃の程
度を緩和するように落下距離を小さくしなければならな
い、しかし、そのようにすると作業効率が低下する。し
たがって１通常の作業手順で作業しても、デザイン面を
傷付けないような工夫が強く要望されている。For this reason, it is recommended to use a stand for the receiver to avoid leaving dents on the design surface. 1. The falling distance must be shortened to reduce the impact of the falling cast product, but doing so will reduce work efficiency. Therefore, there is a strong demand for a device that does not damage the design surface even if the work is carried out using normal work procedures.

設けたことを必須の構成とするものである。(Means for Solving the Problems) The as-cast shape of the vehicle wheel casting of the present invention was developed in order to solve the above-mentioned problems all at once. It is essential that a protrusion higher than the level of the design surface be provided on the flange portion or the disk portion on the design surface side of the disc.

側円周に環状のものを付けても良い。These protrusions may be provided in three or more places on the outermost edge of the flange portion or on the outermost edge of the disk portion, or may be annular protrusions on the outermost circumference of the outer edge of the flange portion or disk portion. You may also attach one.
軽合金はアルミニウム合金またはマグネシウム合金であ

る。(Operations and Examples) As shown in Fig. 1, an as-cast aluminum alloy vehicle wheel wheel (1) is removed from the mold and the receiver is placed on a stand (2).
When dropped upward, there is a skin-like protrusion (3) on the outermost edge of the flange, and this protrusion (3)
) is higher than the design surface level (5) with respect to the plane (4), so the design surface (8) and the receiver do not collide with the base (2) surface. Therefore, the design surface (6) is not damaged. The same applies to the case where the outermost edge of the disk portion (7) is higher than the design surface tree* (5).

がある。(Effects of the Invention) The as-cast shape of the vehicle wheel casting of the present invention has a protrusion higher than the design surface level on the flange portion or disk portion on the design surface side, so that the as-cast casting product can be received. When dropped onto a stand, the design surface will not collide with the stand, so the design surface will not be damaged, and these protrusions will be removed later in the J-cutting process to create a finished product. It has the advantage of being able to efficiently remove as-cast castings using normal work procedures and producing good quality products with high efficiency.
The present invention greatly contributes to the development of industry.
