本発明はアルミニウム合金のサークル材を深絞り加工し
たカップ２個を接合して構成したバギー車等のチューブ
レスタイヤ用アルミニウム合金ホイールの製造方法の改
良に関する。DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a method for manufacturing an aluminum alloy wheel for tubeless tires such as buggies, which is constructed by joining two cups deep-drawn from aluminum alloy circle material. Regarding improvements.
（０）従来の技術
ホイールは、リムの縁部を外側にカールしたり、或は内
側にカールしても間隔を残していた。(0) In conventional wheels, even if the edge of the rim is curled outward or inward, a gap remains.
二のようにリムの縁部をカールすることは、ホイールの
強度上大変有利であるが、外側にカールした場合、バギ
ー車の使用状態により、縁部が障害物に当ることが多く
、カールが次第に疵つき開いてきてホイールの強度が低
下する欠点があった。Curling the edge of the rim as shown in step 2 is very advantageous in terms of the strength of the wheel, but if it curls outward, the edge often hits obstacles depending on how the buggy is used, and the curl is The problem was that the wheels gradually became cracked and cracked, reducing the strength of the wheels.
また内側にカールする場合、タイヤに押えられてカール
が開いてくることはないが、間隙があってカールが閉じ
ていない場合は、完全に閉じている場合に比し強度が弱
いといへ欠点があった。In addition, when curling inward, the curl will not open up due to pressure from the tire, but if there is a gap and the curl is not closed, there is a disadvantage that the strength is weaker than when it is completely closed. there were.
従って内側にカールして完全に中空の環状になるようカ

ミニウム合金材であるため、カール部に疵が生じたり、
カール部に細線状の屑を巻き込むことがあった。Therefore, all you have to do is curl it inward to form a completely hollow annular shape, but if you curl it with a press, it may cause scratches on the curled part because it is an aluminum alloy material.
Thin line-shaped debris was sometimes caught in the curled portion.

なる側をひどく傷つける。In the edge cutting process shown in FIG. 3e, burrs appear as shown in the enlarged view of FIG. 4. The upper part of the rough cut surface is cleanly cut by the blade, but the lower part is cut by a shear and has a rough fractured surface. When this is edge-bent in the process shown in Fig. 3 f, that is, narrowed down to a U-shaped cross section, the outer surface is elongated and the outer corner (12) becomes sharp as shown in Fig. 5, and the cut-like burrs of the plate edges are shaped like an arc. It is often released in the form of lint (12°) and adheres to oily sides. Furthermore, when the edges are bent at 45° as shown in Figure 6 in the process of Figure 3g and narrowed down, the remaining burrs and sharp corners are pushed by the punch and come off, turning into thread-like lint that can be removed by the punch. It gets squeezed in between and seriously damages the side of the rim side edge (4) that will be the tire contact surface (4゛).

くことは空気漏れを多くする原因であっｔ：。However, the hump portion (6) and the bead seat portion (5) are surfaces that maintain airtightness with the due press tire, and must not have any flaws that may cause air leakage. The tire contact surface (4') of the side edge of the rim (4) must be free of flaws and requires dimensional accuracy. Scratches on such surfaces can lead to increased air leakage.

る。このＲ加工後、第３図ｇの縁４５゜ル加工をする。Figure 7 shows the cup with the edges bent after the process shown in Figure 3 f, placed on a rotating table (the rotating table is not shown) #1lli (4")
When the cup is rotated while pressing the piece (11) which has a concave R surface, the corner is rounded and has a smooth R surface, as shown in the cross-sectional view of the edge (4'') Lt No. 8rlA. After this R machining, process the edge 45° as shown in Figure 3g.

とになりよくない。In addition, after cutting the edge in Figure 3e, R processing is performed using the above-mentioned piece,
After that, when the edge bending process is performed as shown in Figure 3 f, the outside will be pressed when it is drawn into the die, and the R part will have a corner as shown in Figure 9, which will damage the bead seat (5) when the edge bending process is performed. That's not good.
