Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The industrial field of application of the present invention relates to an apparatus for manufacturing fiber-reinforced metal composite materials. This is a manufacturing device for a fiber-reinforced metal composite material that can perform two steps in one device: casting metal to form a billet and extrusion pressing the billet.

[Conventional technology]

Fiber-reinforced metal composite materials (hereinafter referred to as FRM) are made by impregnating carbon fibers, ceramic fibers, or powder particles with molten metal such as aluminum (referred to as matrix metal) to form a composite material. It refers to the material that is used to obtain various molded products.

The process of manufacturing a product using an extrusion press using such FRM has been carried out through the following steps.

For example, in the production of FRM using whiskers, which are short fibers, (1) water, alcohol, etc. are used as a binder;
It is pressed into a predetermined shape and hardened.

After that, the binder is removed by drying, and the preform material is made.
The process involved three steps: impregnating a preform material with aluminum to make a billet, and (3) extruding the billet using an extrusion press.

[Problem that the invention seeks to solve]

However, each of the six processes mentioned above requires separate equipment, takes up space, and requires the movement of materials, resulting in extremely poor production efficiency. ] In the present invention, in order to solve the above-mentioned problems, after impregnating a preform material with molten matrix metal such as aluminum and forming a billet using the same container, the position of the container is changed and an extrusion press is applied. We adopted a structure that allows extrusion molding.

[For production]

If such a structure is adopted, billet manufacturing equipment and
Extrusion press devices can be combined into one device, and a preform material molded by another device is set in a container and a matrix metal is impregnated into the preform material by an injection molding method. By simply changing the position of the container, extrusion molding can be carried out in conjunction with an extrusion press device, and billet production and extrusion product production can be performed in one device.
