Problems solved by technology

[0003] 1. The extrusion process of low-volume-fraction particle-reinforced Al-based composite materials in the prior art is relatively complicated, requiring multiple extrusion production equipment to operate simultaneously, resulting in high production costs;
[0004] 2. The extrusion ratio of the low volume fraction particle reinforced Al-based composite material in the prior art is low and the design of the extrusion die is unreasonable, thereby affecting the production efficiency of extrusion molding and causing a low yield rate of the finished product;
[0005] 3. In the existing technology, the cavity mold needs to be used at high temperature for a long time, and it is impossible to perform a reasonable cooling operation after use, resulting in an increase in the number of use and maintenance of the cavity mold and a low service life

Abstract

The invention discloses an extrusion method for a low-volume-fraction ceramic particle reinforced aluminum matrix composite bar. A support, a conveying mechanism, a heating and cooling mechanism and an extrusion die mechanism are included, wherein the conveying mechanism is used for feeding, conveying and extruding materials, the conveying mechanism comprises a barrel body and a pipe body, and the barrel body is connected to the interior of the support through a screw. When an extrusion device is used, an operator throws the materials through a feeding hopper, one end of a screw rod is installed on a rotating shaft of an external driving motor through a coupler, the motor is started to drive the screw rod to rotate in the pipe body, the materials are conveyed through the screw rod in the pipe body, and crushing is conducted on the inner wall of the pipe body and in a spiral groove in the conveying process, the conveying volume of the materials is reduced, meanwhile, in the conveying and extruding process, a heating pipe is used for heating the interior of a cavity mold, the materials are rapidly softened and extruded, and the extruding efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of composite material processing, and Extrusion device. Background technique [0002] It is well known that the particulate reinforced aluminum matrix composite is the most mature variety in the metal base composite. The reinforcing body used in this composite material is mainly silicon carbide and alumina, and a small amount of titanium oxide and boride, titanium oxide, and a particle size of titanium oxide and titanium oxide, which is generally about 10 microns. The substrate can be pure aluminum, but most of them are various aluminum alloys, including high-performance aluminum lithium alloys, however, existing low-volume fraction ceramic particles reinforced aluminum-based composite bars extruded production still have a problem: [0003] I. The existing low-volume fractional particle enhancement Allate composite material is more complicated, and a plurality of extruded equipment is required to operate simultaneo...
