本発明は自動車用車輪のデイスクにおけるナツ
ト座周辺部を加工硬化させた自動車用車輪の製造
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing an automobile wheel in which the area around the nut seat of the disk of the automobile wheel is work-hardened.
従来、第１図に示すような自動車用車輪１にお
いて、耐久強度上も弱点になつているのは、自動
車の車軸ハブボルトへの取付穴２の強度である。
即ち、第２図に示すように自動車用車輪１の取付
穴２を所定のハブボルト３およびナツト４で締付
けた時ナツト座外周部ａにおいて疲労破壊を起す
ことが知られている。 Conventionally, in a wheel 1 for an automobile as shown in FIG. 1, the weak point in terms of durability and strength is the strength of the mounting hole 2 to the axle hub bolt of the automobile.
That is, as shown in FIG. 2, it is known that when a mounting hole 2 of an automobile wheel 1 is tightened with a predetermined hub bolt 3 and nut 4, fatigue fracture occurs at the outer periphery a of the nut seat.
上記取付穴２のナツト座外周部の耐久強度に最
も影響を及ぼす要因としては、車輪の材質、車輪
の取付面寸法精度、設計形状或いは板厚等であ
る。上記要因の中で、車輪の材質、取付面寸法精
度の変更は加工性及び生産性の面で制限があり、
取付面の設計形状の変更においても、ブレーキド
ラム及び車軸ハブとの寸法関係から極めて限られ
た寸法形状になり、板厚の変更のみが最も自由が
効いていた。 The factors that most affect the durability and strength of the outer periphery of the nut seat of the mounting hole 2 are the material of the wheel, the dimensional accuracy of the mounting surface of the wheel, the design shape, the plate thickness, etc. Among the above factors, changing the wheel material and mounting surface dimensional accuracy has limitations in terms of workability and productivity.
Even when changing the design shape of the mounting surface, the size and shape were extremely limited due to the dimensional relationship with the brake drum and axle hub, and only changing the plate thickness was the most flexible.
このため、従来一般的には車輪の耐久力を増す
ための方法として、素材板厚を厚くする方法が最
も多くとられており、しかも効果が大きかつた。
しかし、車輪の耐久力を増すために板厚を厚くす

量化の要求に対処できず、製品のコストアツプに
つながるという欠点があつた。 For this reason, in the past, the most common method for increasing the durability of wheels was to increase the thickness of the material, and this method was highly effective.
However, increasing the thickness of the wheel in order to increase the durability of the wheel increases the weight of the product, which cannot meet the demands of the automobile industry for weight reduction, leading to increased product costs.
本発明は上記従来の欠点を除去するためになさ
れたものであり、取付部の板厚を厚くせずに耐久
力を増した自動車用車輪の製造法を提供するもの
である。 The present invention has been made to eliminate the above-mentioned conventional drawbacks, and provides a method for manufacturing an automobile wheel that increases durability without increasing the thickness of the mounting portion.

The nut seat 7 is pre-cut into a countersunk shape having a curvature R 1 or an angle α 1 smaller than the shape of the tightening surface of the nut used for attachment to the wheel hub, that is, the curvature or angle of the nut spherical surface or nut tapered surface. A press having an upper mold having pins of the same number as the mounting holes 6 drilled in the disk 5 and arranged at the same pitch, and a lower mold arranged with respect to the upper mold. Coining the nut seat 7 processed into the shape of a countersunk by a machine,
It is formed to have a curvature R 2 or an angle α 2 that is approximately the same as the curvature or angle of the nut spherical surface portion or nut tapered surface portion.

The nut seat 7 is cut into a countersunk shape having a curvature R 1 or an angle α 1 smaller than the shape of the tightening surface of the nut used for attachment to the wheel hub, that is, the curvature or angle of the nut spherical surface portion or nut tapered surface portion. The nut seat 7 is coined in the same manner as in Example 1 to form the nut seat 7 with a curvature R 2 or angle α 2 that is approximately the same as the curvature or angle of the nut spherical surface portion or the nut taper surface portion, and By coining the area around the seat at the same time, the work hardening of the area around the nut seat is further improved.

優れた効果を有する発明である。 As described above, in the present invention, since the nut seat of the disk mounting hole is finished by coining processing, the surrounding area of the nut seat is work hardened, its hardness increases, and the fatigue durability also increases accordingly. Therefore, without changing the material of the wheel or the design shape of the mounting surface,
Moreover, a highly safe wheel with extremely good mounting surface dimensional accuracy can be obtained. Furthermore, since the thickness of the material plate does not need to be increased, the weight of the product can be reduced and a high-quality product can be obtained, which is an excellent invention.
