Structural metal fuse material additive device and fuse manufacturing technology thereof

Abstract

The invention discloses a structural metal fuse material additive device. The structural metal fuse material additive device comprises fuse feeding systems, robots, a work platform, welding guns, molding parts, a numerical control milling system, a control system and a welder main engine. The robots are symmetrically distributed on the two sides of the work platform, and each robot is separately fixed to an I-steel truss; each fuse feeding system and the corresponding welding gun are separately fixed to a robot shaft, wherein the fuse feeding systems can feed fuses in a single-fuse or multi-fuse mode; the welder main engine is electrically connected with the welding guns and used for controlling the voltage, the current and the fuse feeding speed in the material additive process of the metal fuses; the control system is electrically connected with the robots, the welder main engine, the numerical control milling system and the fuse feeding systems, and used for controlling the robots, welder main engine, the numerical control milling system and the fuse feeding system to be turned on or off and controlling the process. By means of the structural metal fuse material additive device, the quick fused deposition of larger structural metal is guaranteed, and meanwhile, the requirements that the material additive manufacturing of tiny structures can be achieved, the size precision of the molding parts can be controlled, and the surface smoothness is high are met.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and relates to a fuse additive device and a process, in particular to a fuse additive device for metal structural parts and a fuse manufacturing process thereof. Background technique [0002] Additive manufacturing technology is also known as 3D printing or rapid prototyping. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, or fuses, to construct a three-dimensional entity by stacking and accumulating layer by layer. Currently commonly used additive manufacturing methods include: laser powder bed fusion, electron beam powder bed fusion, laser coaxial powder feeding, arc fuse forming technology, etc. [0003] Laser powder bed fusion and electron beam powder bed fusion are only used in the field of processing and manufacturing of fine structural parts due to the limitation of the size of the molding cavity and the high cost...

AI Technical Summary

Problems solved by technology

Although the excess size and thickness can be removed in the secondary machining process, this will inevitably increase the amount of milling, and some small structures may not be able to achieve milling

Therefore, it is necessary to overcome the technical shortcomings of conventional technology to manufacture large and complex metal structures
