Vertical casting and extruding composite preparation device and method of coating structure metal composite material

Abstract

The invention discloses a vertical casting and extruding composite preparation device and method of coating structure metal composite material. The device comprises a starting material blocking block,an extruding table, an extrusion female die, an extrusion male die, a casting female die and an extrusion composite cylinder, a plurality of connecting columns are arranged at the bottom of the extrusion table, the extrusion female die and the casting female die is arranged on the extrusion table, the extrusion male die is arranged in the extrusion female die, the extrusion table is provided witha discharge hole and a casting feed hole, the discharge hole corresponds to the discharge hole of the extrusion female die, the discharging hole of the casting female die is connected with the casting feeding hole, the outlet of the casting feeding hole is communicated with the discharging hole, the extruding composite cylinder is arranged at the bottom of the extruding table, the feeding port ofthe extrusion composite cylinder is communicated with the discharge hole, and a starting material blocking block is arranged at the discharge port at the bottom of the extrusion composite cylinder. The blank defect is eliminated by extruding the inner-layer blank, meanwhile, a new metal surface is generated, and the composite material which is high in surface binding force and excellent in mechanical property is obtained through subsequent extrusion composite forming.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a vertical cast-extrusion composite preparation device and method for clad structural metal composite materials. Background technique [0002] Metal composite materials are new composite materials prepared by using composite technology to make two or more metals with different physical, chemical and mechanical properties achieve firm metallurgical bonding at the interface. Metal composite materials have incomparable advantages over a single metal material. Through reasonable material selection and proper combination, not only can the own characteristics of the constituent materials be retained, but also the properties of the constituent materials can be complemented by the composite effect, so that the composite material can obtain Excellent overall performance. Composite materials such as copper-clad aluminum, copper-clad steel, and aluminum-clad magnesium ...

Problems solved by technology

The traditional rolling and crimping method and the cladding welding method are all solid-solid composite methods, which have the disadvantages of long production process and high cost.

The Beijing University of Science and Technology has developed the double-metal clad material continuous casting direct composite forming method and the horizontal continuous casting direct composite forming method, which have disadvantages such as high investment costs, low production efficiency, and large energy consumption.

CN103920734A proposes an extrusion molding die and method in the semi-solid preparation method of an aluminum-clad magnesium composite pipe. Each layer of material needs to be split and welded in its own mold, and its strength is difficult to guarantee. Finally, solid-solid extrusion composite is realized. , the interface strength is not high
