【発明の詳細な説明】
本発明は、アルミニウム等の金属材のしごき加工方法に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for ironing metal materials such as aluminum.
例えばＤＩ缶の製作においては、金属円板をカッピング
してから再絞り工程を経て、カップの側壁にしごき加工
を加えて延伸している。又、熱交換器における硬質フィ
ンはパンチ・バーリング後しごき加工を加えている。For example, in the production of DI cans, a metal disk is cupped, then subjected to a re-drawing process, and the side walls of the cup are ironed and stretched. In addition, the hard fins in the heat exchanger are ironed after punching and burring.

５０％が限界である。したがって、前３Ｗｉのようなり
１缶や硬質フィンのしごき加工は概ね限界しごき率以上
の加工度を要するので、しごき加工を複数回行なわざる
を得ない。The ironing process in these conventional processing techniques W is performed using a processing tool having a shape as shown in FIG. That is, in FIG. 1, 1 is a die for ironing, and 2 is a punch for ironing. 2 has a cylindrical body 4 with a diameter. Then, a certain parallel gap (
The material is ironed by d-D). When using an ironing tool with such a structure, when the object to be ironed is an aluminum alloy, the ironing rate for one time is 40 to 40.
50% is the limit. Therefore, ironing a can or a hard fin like the previous 3Wi generally requires a working degree higher than the limit ironing rate, so the ironing process must be performed multiple times.
そのため、しごき加工工程の数に相当する工具を必要と
するばかりでなく、プレス加工時の送り粘度を厳しく管
理覆る必要がある。Therefore, not only are tools required corresponding to the number of ironing steps required, but also it is necessary to strictly control the feed viscosity during press working.
本発明は以上の従来の問題点を解決すべくなされたもの
で、その要旨はグイ部材の成形開口と、該成形開口に進
入するポンチ部材間に形成される空隙部で金属（Ａを減

ある。The present invention has been made to solve the above conventional problems, and its gist is to reduce the thickness of the metal (A) in the gap formed between the forming opening of the goo member and the punch member entering the forming opening. In this method, the gap between the die member and the punch member is formed to a size that gradually decreases as the bonding portion 4A advances, and the metal material is squeezed by the gap thus formed to gradually reduce the thickness of the metal. This is a method of ironing wood.
これを図面によって説明すると、第２図において、しご
き用ダイス１は前述の従来法におけるしごき用ダイスと
同じものでよいが、しごき用ポンチ５はガイド部Ｂに続
いてテーパ一度θで長ざ℃のしごき加工部Ａを右する。To explain this with the drawings, in FIG. 2, the ironing die 1 may be the same as the ironing die in the conventional method described above, but the ironing punch 5 is connected to the guide portion B and is tapered once at θ. Turn the rolling part A to the right.
この場合、ガイド部Ｂの直径Ｄ１としごき加工部Ａ＋７

) Maximum diameter part 1') 2 Which relationship is D2 = DI + 2J2t
It is an O. Note that the guide portion B is convenient for alignment and may be omitted.
口のようなしごき用ダイス１としごき用ポンチ５どを用

例を示すもので、しごき用ボンデ２は従来と同様のもの
を使用し、しごき用ダイス６のしごき部７をテーパ一度
θで、間口部の直径ｄ２かう、それより小さい直径（Ｉ
１に向ってテーパー状にしたものである。When the material is squeezed using the mouth-like ironing die 1 and the ironing punch 5, ironing starts at the part with a diameter D1 to the material ladder processing section, and the ironing die 1 of the ironing punch 5 is pressed. As the ironing process progresses, the diameter of the ironing part A increases, and the gap between the ironing die 1 and the inner wall of the ironing die 1 gradually decreases, thereby gradually reducing the thickness of the workpiece. Fig. 3 shows another embodiment, in which the ironing bond 2 is the same as the conventional one, the ironing part 7 of the ironing die 6 is tapered once by θ, and the diameter of the opening part is d2, and small diameter (I
It is tapered towards 1.

The gap with the surface of the ironing punch 2 is gradually reduced, and the thickness of the metal material is gradually reduced.
このように、本発明の加工法によれば、−回のしごき加

。As described above, according to the processing method of the present invention, the limit ironing rate in - times of ironing is faster than the limit ironing rate in the conventional method. 1? increase. therefore,
For example, in the machining of hard fins, what was conventionally done in two steps can now be done in one step. In other words, the diameter of the punch before the ironing process can be increased to a large extent, and stretch flange processing can be easily performed, thereby making it possible to reduce the incidence of flare cracking.
又、■程数を減少し得ることは、減少１稈相当の工具が
不必要となるばかりでなく、例えばプレス加工時の送り
精度を厳しく管理づる必要性も最小限にすることができ
て、製造技術上極めて価値がある。Also, being able to reduce the number of steps not only eliminates the need for tools equivalent to one culm, but also minimizes the need to strictly control feed accuracy during press processing, for example. Extremely valuable in terms of manufacturing technology.
次に具体的な実施例について述べる。Next, a specific example will be described.
