Abstract

The invention relates to a metal additive manufacturing device with the combination of fusing and forging. The metal additive manufacturing device comprises a base unit, a fused deposition unit, a forging unit, a driving unit and a control unit, wherein the fused deposition unit, the forging unit, the driving unit and the control unit are supported by the base unit. A workpiece to be machined is further arranged on the base unit. Material fused deposition is carried out on the surface of the workpiece through the fused deposition unit. The fused deposition unit is driven by the control unit to move according to a worked out path to make the workpiece be formed. The workpiece is forged through the forging unit in the workpiece forming process, and forging is always kept on a track of fused deposition materials and lags behind fused deposition points. Compared with the prior art, the metal additive manufacturing device with the combination of fusing and forging enables the fused deposition materials to be forged, so that the fused deposition materials are compact, defects of looseness, holes and the like are eliminated, dendritic crystals and other undesirable organizations can be smashed, grain refinement of the materials is promoted, grains of the materials are finer, and the surface quality of the forged materials is higher.

Description

technical field [0001] The invention relates to the technical field of metal additive manufacturing, in particular to a melting and forging composite metal additive manufacturing device. Background technique [0002] Additive manufacturing technology is a new type of material manufacturing technology. In the field of metal additive manufacturing, it includes selective laser melting, direct metal sintering, laser net shape manufacturing, electron beam rapid prototyping, plasma deposition direct manufacturing, arc deposition rapid prototyping technology, etc. [0003] At this stage, different additive manufacturing technologies have their own advantages and disadvantages. Laser-based rapid manufacturing technology has high cost, low deposition efficiency, and large thermal shock of materials: electron beam rapid prototyping needs to be realized in a vacuum environment, which has a large impact on powder; The parts that can be formed by plasma beam and arc forming technology a...
