Abstract

The invention discloses a robot posture controlled electric arc deposition laser forging additive manufacturing method and equipment for complex structural components. By adopting a robot posture control scheme, the space position of a melt forming part on a machining region can be freely adjusted, and the melting material flowing, falling and collapsing problems caused by the gravity action are solved. Meanwhile, the force effect of shock waves induced by pulse laser is used for reducing or eliminating internal defects and residual stress of a melting region and refining grains of the melting region, and the mechanical performance of the formed metal parts is improved. By means of the robot posture controlled electric arc deposition laser forging additive manufacturing method and equipment, the complex structural metal parts can be directly and rapidly formed, the efficiency is high, and the quality of the formed metal parts is relatively high.

Description

Technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to an arc deposition laser impact forging additive manufacturing method of complex structure parts controlled by robot attitude, and equipment for realizing the method. Background technique [0002] As a new type of manufacturing technology with the idea of ​​layered manufacturing and layer-by-layer accumulation, additive manufacturing technology has great advantages in rapid prototyping of complex structures. In recent years, it has become the subject of extensive attention and research in the field of material processing. [0003] Direct rapid prototyping technology for manufacturing metal parts is generally regarded as the most difficult frontier development direction in the field of additive manufacturing technology. It is based on the principle of plane discretization and accumulation. First, the 3D CAD model of the part is obtained in the CAD modeling syste...
