Abstract

The invention relates to a method for manufacturing metal layered composite pipes. The method comprises the following steps: 1) adopting a horizontal metal profile extruder, the extruder includes three storage barrels independently arranged side by side and arranged parallel to the axis, and a machine for extruding the ingot to be extruded in each storage barrel Extrusion rods and oil cylinders that drive the movements of each extrusion rod; 2) Heating the base layer billet and the cortex billet that are compatible with the corresponding filling cylinder to the corresponding extrusion temperature; 3) heating the heated base layer billet and cortex billet The cortex billet is placed in the corresponding material container; 4) The oil cylinder drives the extrusion rod to extrude the base billet, so that the base billet is extruded into the extrusion mold and welded into a base pipe as the core; 5) Then The oil cylinder drives the extrusion rod to extrude the cortex billet, and the cortex billet spans to the outside of the mold core to realize welding and extrusion forming to complete the coating. The method can effectively solve the technical problem of non-uniform thickness of the head-to-tail coating skin layer produced by the forward extrusion of the composite ingot.

Description

technical field [0001] The invention relates to a method for manufacturing composite pipes, in particular to a method for manufacturing metal layered composite pipes. Background technique [0002] Metal layered composite material refers to a material with excellent comprehensive performance that is made of two or more layers of metals with different properties through a certain composite method. It can not only improve the comprehensive performance of the material, but also reduce the cost Metal usage, which is especially important in view of dwindling natural resources and increasing production demands. [0003] With the development of modern industrial technology and various new technologies and new industries, people's requirements for material performance are increasing day by day. Under certain working conditions, the performance of a single component material has been difficult to meet the requirements. Metal layered composites have become one of the research hotspots...
