Semi-solid horizontal extrusion mold for double-layer composite pipes and application thereof

Abstract

The invention discloses a semi-solid horizontal extrusion mold for double-layer composite pipes and application thereof, and relates to the technical field of production of double-layer metal composite pipes. The mold comprises a base, an extrusion sleeve, an extrusion rod, an inner extrusion mold and an outer extrusion mold. The mold, providedby the invention, is simple in structure and convenient for manufacturing and use, can be applied to continuous production of metal composite pipes with different inner and outer materials, and is low in energy consumption, short in flow, flexible in structure and excellent in reusability, interfaces can reach high strength of metallurgical bond,and high-quality and high-efficiency semi-solid extrusion molding can be realized.

Description

Technical field

[0001] The invention relates to the technical field of production of double-layer metal composite pipes, in particular to a mold and method for preparing aluminum-magnesium double-layer pipes. Background technique

[0002] The composite double-layer pipe refers to a pipe made of dissimilar metals in the inner and outer layers through a certain processing method. The inner and outer layer materials have different properties and can meet the requirements of different working environments.

[0003] At present, composite double-layer pipes have broad application prospects in the petroleum industry, aerospace, home appliance manufacturing, and automobile industry. With the continuous development of my country's economy, the national industry's demand for composite pipes continues to increase, and there are higher and higher requirements for the performance and quality of pipes. In addition, due to the increasingly prominent environmental problems in our country and the ...
