Abstract

The invention requests protection of a multi-material metal gradient component efficient forming device and method. The device comprises at least three metal premelting units and further comprises a wire feeding transmission device, four TIG welding gun heads, a three-dimensional forming platform and an atmosphere protection device, wherein the three metal premelting units are arranged at the center position of a whole working space and are tightly arranged at an angle of 120 degrees correspondingly, each metal premelting unit is provided with a welding wire conveying hole, the four TIG welding gun heads are located in four quadrants divided by taking the premelting units as the center points and are located on angular bisectors of all the quadrants, the three-dimensional forming working platform is arranged below the premelting units, and the whole forming process is performed under the atmosphere protection of inert gases. By means of the multi-material metal gradient component efficient forming device and method, efficient, low-cost, integrated and accurate additive manufacturing of metal gradient material components can be realized.

Description

technical field [0001] The invention belongs to the technical field of functionally graded component manufacturing, and relates to a multi-bypass premelting forming device and method, in particular to a medium and large-sized aluminum-based gradient component efficient forming device and method. Background technique [0002] Due to its high specific strength, high specific modulus, high corrosion resistance and other advantages, aluminum alloys are widely used in rail transportation, chemical industry, aerospace and other fields. Adding functionally graded materials to the aluminum alloy can make the composition of the components change gradually, realize the complementary advantages of material properties, and make each part of the components have different properties, so as to meet the needs of the working environment to the greatest extent and give full play to the advantages of comprehensive performance. At present, the common preparation methods of aluminum alloy gradie...
