It is related to.

より複合材３が押出される。(Background Art) Conventionally, there are various methods for producing composite materials using an extruder, including the method shown in FIG. 1, for example. In the figure, 4 is a ram, 5 is a cylinder, 6 is a hollow mandrel for inserting the core material, and 7 is an extrusion die. When the ram 4 applies extrusion pressure in the direction of arrow 8 to the sheath metal 2 and the core material 1 is inserted through the hollow mandrel 6, the extrusion die 7
The composite material 3 is then extruded.

により偏肉の大小は決定され、工具形状を変更しない限
シ製造途中で偏肉を矯正することは不可能であった。In this extrusion method, the extrusion direction of the composite material 3 and the outer sheath metal 2 are
Since the supply directions of the two are different, the pressure of the outer sheath metal 2 around the core material 1 cannot be balanced, so it is desirable to prevent uneven thickness of the outer sheath metal. As a method to prevent this uneven thickness, for example, a bridge die method (for example, Japanese Unexamined Patent Publication 1973-
No. 144322), or a hole-and-hole die method (No. 144322), in which supply holes with different cross-sectional areas are provided at peripheral positions between the sheathing metal supply chamber and the extrusion diene chamber to uniformize the pressure balance.
For example, methods such as JP-A-55-144323 (described later) have been proposed. However, even with these methods, the purpose is to balance the pressure by adjusting the flow of the sheath metal with the tool, so the size of the uneven thickness is determined by the flow of material once determined by the tool, and the tool shape cannot be changed. Unless otherwise specified, it would be impossible to correct uneven thickness during manufacturing.
