本発明は鋼板素材をもつて直線管やテーパ管を

めである。 There is a conventional tube forming apparatus that includes an upper mold located above a mandrel and horizontal molds located on the left and right sides of this mandrel (Japanese Patent Publication No. 31111/1983). This conventional equipment first performs the U-bending process, and then performs the final O formation, but a large pressure force is required when forming the O, which inevitably increases the size and cost of the equipment itself, and avoids reducing the formation speed. It is something that cannot be done. The main reason why this large pressing force is required is that even after U-bending, the areas near both ends remain flat, so it is extremely difficult to form both ends of this flat plate into an arc when applying pressure to form an O. This is because it requires a large pressing force, approximately twice as much.
そこで本発明はなるべく小さな加圧力で管成形
が可能であるとともに自動化が可能な装置を提供
することを目的とするものである。 Therefore, an object of the present invention is to provide an apparatus that is capable of forming tubes with as little pressure as possible and that can be automated.

つている。 Furthermore, an upper die 11 is provided above the mandrel 5 so as to be movable up and down. It is something that is driven. In the center of the lower surface of the upper mold 11, a mold cavity 14 having an inner arc shape corresponding to the outer shape of the mandrel 5 is bored, and at both ends of the lower surface, arc-shaped mold cavities 10 are formed at the rear upper corners of the horizontal molds 6, 6a. Arc-shaped cavities 15, 15a corresponding to 10a are formed. Further, the upper mold 11 is provided with electromagnets 16, 16, which act as holding means for attracting and holding the steel sheet material P to be formed.
次に本発明の作動状態について説明する。 Next, the operating state of the present invention will be explained.
先ず本装置を第１図の状態に設定する。この状
態では横型６，６ａは油圧シリンダ７，７ａによ
つてマンドレル５に接合し、上型１１は上方に位
置している。そこで横型６，６ａ上面に成形すべ
き被加工材である鋼板素材Ｐを所定の位置に合せ
て載置する。 First, the apparatus is set to the state shown in FIG. In this state, the horizontal molds 6, 6a are joined to the mandrel 5 by hydraulic cylinders 7, 7a, and the upper mold 11 is located above. Therefore, a steel plate material P, which is a workpiece to be formed, is placed on the upper surface of the horizontal molds 6, 6a in a predetermined position.

巣１４とマンドレル５とによつて中央部より二つ
折りの状態に折曲する。そのため素材Ｐは上型１
１の電磁石１６，１６の吸引力より解放される。
そこで上型１１を引き上げると、第４図示のよう
に素材Ｐはマンドレル５上に載置しているが、こ
の素材の両端部は鋼板自身の復元力によつて幾分
拡開する。そのため、第５図示のように再び横型
６，６ａを進出させ、マンドレル５に圧接させる

第６図示のように横型６，６ａを後方へ移行させ
ても素材Ｐ自体は完全に塑性変形している。その
ためこの後は、従来の適当な管成形装置にて容易
に管が成形できるのである。 Then, the upper die 11 is lowered to perform press forming, but at this time both ends of the material P are
5, 15a and the mold nests 10, 10a of the horizontal molds 6, 6a are pressed together to bend into an arc shape, and then when the upper mold is raised, the material P is also moved by the electromagnets 16, 1 of the upper mold.
6a and rises while adsorbed to the upper mold. The horizontal types 6 and 6a have hydraulic cylinders 7 and 7, respectively.
Move backward by a. This is the situation shown in FIG. Therefore, as shown in Fig. 3, the upper mold 11
When the material P is lowered, the material P is folded into two from the center by the mold cavity 14 at the center of the lower surface of the upper mold and the mandrel 5. Therefore, the material P is the upper mold 1
It is released by the attractive force of the electromagnets 16, 16 of 1.
When the upper mold 11 is then pulled up, the material P is placed on the mandrel 5 as shown in the fourth figure, but both ends of the material are expanded somewhat by the restoring force of the steel plate itself. Therefore, as shown in Figure 5, when the horizontal molds 6, 6a are advanced again and brought into pressure contact with the mandrel 5, the material P is further deformed inward by the curved surfaces 9, 9a of the front surface of the horizontal molds and the mandrel. Therefore,
Even when the horizontal molds 6, 6a are moved backward as shown in FIG. 6, the material P itself is completely plastically deformed. Therefore, the tube can then be easily formed using a suitable conventional tube forming apparatus.
