Abstract

The invention discloses an electric arc 3D printing device for magnetic alloy tubular structural components. The electric arc 3D printing device comprises a welding base, a component substrate, a cooling system, a linkage lead screw, a driving device and a welding gun. The component substrate is arranged on the welding base, and the cooling system is arranged below the welding base. The component substrate is fixedly connected with the linkage lead screw, and the component substrate moves up and down along the linkage lead screw. The driving device drives the linkage lead screw, and the linkage lead screw makes cooperation motion with the welding process. The welding gun conducts build-up welding at the position above the component substrate to form a magnesium alloy tubular structural component. The invention further discloses an electric arc 3D printing method for magnesium alloy tubular structural components. The electric arc 3D printing method comprises the following steps that (1) a first layer ringlike texture is constructed; (2) a second layer annular texture is constructed, and meanwhile the cooling system is started; and (3) the step (2) is conducted again until the needed component is formed. The electric arc 3D printing device and method for magnetic alloy tubular structural components has the advantages of improving the product forming efficiency, lowering the product manufacturing cost, and saving the development time cost.

Description

technical field [0001] The invention relates to an arc 3D printing device and a printing method for a magnesium alloy tubular structural part, and belongs to the field of magnesium alloy arc 3D printing additive manufacturing technology. Background technique [0002] Arc 3D printing belongs to the category of additive manufacturing technology. It is based on the principle of discrete-stack manufacturing. There are many implementation methods for additive manufacturing technology. Many successful commercialized additive manufacturing technologies use non-metal forming materials. Its application in the industrial field is limited, and metal additive manufacturing technology is more important in the industrial field, especially titanium alloys, aluminum alloys, magnesium alloys, etc. Commonly used heat sources for direct forming metal parts mainly include lasers, electron beams, and electric arcs. [0003] Arc 3D printing also establishes the solid model of the part through 3D...
