Abstract

The invention discloses a coaxial wire feeding double-plasma arc additive manufacturing device, and relates to the technical field of additive manufacturing. The coaxial wire feeding double-plasma arcadditive manufacturing device comprises a protection cavity, two welding guns, a welding wire, a wire feeding mechanism and protection gas, wherein the protection cavity structure is of a hollow cavity structure, an inner cavity of the protection cavity is filled with the protection gas, the welding wire is vertically arranged at the axis of the inner cavity of the protection cavity, and the twowelding guns are fixedly installed in the inner cavity of the protection cavity and symmetrically arranged on the two sides of the welding wire; and the wire feeding mechanism is arranged on outer wall of welding wire in a sleeving manner, a through hole is formed in the bottom of the protection cavity, and the welding wire vertically downwards penetrates through the through hole to be fed throughthe wire feeding mechanism. According to the coaxial wire feeding double-plasma arc additive manufacturing device, the problems such as path planning difficulty, complicated robot programming, low forming efficiency and difficulty in forming complex structures caused by paraxial wire feeding in the conventional plasma arc additive manufacturing process are solved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a coaxial wire-feeding double plasma arc additive manufacturing device. Background technique [0002] The plasma arc additive manufacturing technology uses the plasma arc as the heat source to heat and melt the welding wire and deposit it layer by layer to complete the forming of the part. The plasma arc belongs to the compression arc. Compared with the ordinary TIG additive technology, it has the advantages of good arc directivity, high forming precision and high deposition efficiency. At present, this method has been applied to the additive manufacturing of large structural parts such as titanium alloys and aluminum alloys. [0003] But plasma arc additive manufacturing has its disadvantages compared to MIG additive manufacturing or cold metal transition (CMT) additive manufacturing. Since plasma arc welding belongs to non-melting electrode welding, a separate ...
