Manufacturing apparatus of metal composite material

Abstract

Abstract PURPOSE: To continuously and readily manufacture metal composite materials by forming a hollow hole in the central part and supplying a core material into that center hole in the process of exturding an outer layer material. CONSTITUTION: A core material 13 is inserted into the central groove 4 of the outside circumferential groove of a wheel 1 and outer layer materials 14 are inserted into both side grooves 3, 3', thence the wheel 1 is rotated in the arrow direction. The respective outer layer materials 14 impinge against a protrusion 6 and generate high pressure. The raw material at the end are made plastic by this pressure and reach primary chambers 7, 7'. The metals are further extruded from primary dies 8, 8' and reach a secondary chamber 9. On the other hand, a core material 13 is supplied along the outside circumferential groove 4, passes through the core material pass hole 11, is forced into the outer layer materials 14, is covered on the outer layer materials 14 in the secondary die 12 and is extruded as composite material 15. At this time, the supply of the core material 13 is done in the hole of the hollow material and is readily supplied to the central part of the outer layer materials under high pressure.
