った。Conventional technology Conventionally, in the extrusion of metal shapes such as aluminum, a billet is loaded into a container, the billet metal is extruded from a die by the forward movement of a stem, and extrusion is stopped once after leaving a certain amount of day skirt. After that, the container and stem are moved back, and the main shear cuts the day skirt at a position close to the die. Then, the next billet is loaded into the container, and the stem is moved forward to press the front end surface of the billet against the remaining billet metal in the die, thereby extruding it into a press-fit state.

がある。Problems to be Solved by the Invention However, when using the above method, foreign matter such as dirt interposed between the trailing billet and the remaining billet metal in the die, as well as air traps, cause the two metals to bond with each other. The joints tend to be incomplete, and as a result, the strength of the parts of the extruded mold material corresponding to the joints between the billet metals is lower than that of other parts. Therefore, especially in the case of manufacturing a mold material for a structural material, it is necessary to remove a predetermined length of the mold material corresponding to the joint between the billet metal pieces, which poses a problem of lowering the manufacturing yield. Incidentally, although this removal length varies depending on extrusion conditions and the like, it may reach a maximum of 7 m.

The purpose is to provide a method.

とする。Means for Solving the Problems To achieve the above object, the present invention uses a combination container that is divided into a front container and a rear container, and a billet is placed such that the rear end surface of the billet is at the rear end surface position of the front container or a position close to the rear end surface of the front container. After pushing the billet forward until it is in position, load the next billet into the rear container, rotate the rear container around its own axis in an upset state, and pressurize the billet with the stem to join the billet metals in both containers. The gist of the present invention is a method for extruding a shape material, which is characterized by pressing the shape material, and then extruding the shape material into a joined state.

金属同士の接合部に対応する部分の強度が向上される。Operation In the above method, the leading billet metal and the trailing billet metal are joined by rotating the rear container around its own axis with the trailing billet metal upset in the rear container, and applying the billet with the stem. Since this is done by pressing, the two billet metals are pressed against each other while sliding against each other. Therefore, unlike simply being pressed against each other, the bond between the two billet metals is strong. The strength of the part of the extrusion-obtained shape material corresponding to the joint between billet metals is improved.
実施例 以下、この発明の実施例を図面に基づいて説明する。Example Embodiments of the present invention will be described below based on the drawings.

軸方向の移動を行いうるちのとなされている。The difference from conventional extruders is that a combination container (1) is used as the container. That is, this combination container (1) is divided into a front container (8) and a rear container (9). Front container (8
) is a container whose rotation around its own axis is restricted. On the other hand, the rear container (9) is a container that is held so that it can freely rotate around its own axis and move in the direction of its own axis. It is said that the movement was carried out in Uruchino.

As shown in the figure, the trailing billet (13) is pressed by the stem (3) while rotating the rear container (9). The trailing billet (13) is joined integrally with the rear container (9) by the aforementioned upset, and the leading billet metal (11) in the front container (8) is likewise connected to the front container (8). Since the rear container (9) is rotated as described above, the stem (3
), when the trailing billet (13) is pressed, the front end surface of the trailing billet (13) and the rear end surface of the leading billet (11) are brought into pressure contact while rubbing against each other, and as a result, the two are firmly joined. . At that time, debris is generated between the front container (8) and the rear container (9), but this debris is removed by a predetermined scraping device or the like.

コンテナ（９）を回転させる。Although the upset plate (6) was used in the above embodiment, the above extrusion method may be carried out without using this. That is, the leading billet (11) is pushed forward until its rear end surface is located at or near the rear end surface position of the front container (8), and the rear container (9) is moved forward.
At the same time, the rear container (9) is brought close to the front container (8), and while the trailing billet (13) is pressurized by the stem (3), the rear container (9) is loaded with the next billet (13). Rotate.

(13) and the rear container (9) are combined and integrated, and the trailing billet (13) is rotated, and the trailing billet (13) rubs against the leading billet (11) as in the above embodiment. They are pressed together and the two are firmly joined.

When comparing the resulting molds using alloy billets, it was found that the strength of the parts corresponding to the joints between the billet metals was lower than that of other parts of the molds made using the conventional method. On the other hand, the strength of the joined portion of the molded materials obtained by the method of the present invention was almost comparable to the strength of other portions. In addition, when we performed alumite treatment on both molds and observed their appearance, we found that in the molds made by the conventional method, there was a difference between the appearance of the joint part and the appearance of other parts, whereas the molds made by the method of the present invention There was almost no difference between the appearance of the joint and the other parts.

After pushing the billet forward until it is in position, load the next billet into the rear container, rotate the rear container around its own axis in an upset state, and pressurize the billet with the stem, thereby separating the billet metals in both containers. are joined together, and then the shapes are extruded into a joined state. Therefore, the bonding between both billet metals is performed by pressing each other while rubbing against each other, and the bonding between both billet metals becomes strong. Therefore, the strength of the extruded mold material in the portion corresponding to the joint between billet metals is improved, it becomes possible to commercialize the portion that was conventionally removed, and it is possible to improve the manufacturing yield of the mold material. Therefore, according to the method of the present invention, it is possible to manufacture molded materials, particularly structural materials, which require strength with a high yield.
