The invention discloses a vacuum electric scanning supersonic spray deposition
laser additive manufacturing device. The vacuum electric scanning supersonic spray deposition
laser additive manufacturing device comprises a forming
workbench and a
laser spray additive device installed above the
workbench, the laser spray additive device comprises a cold spray head, a laser generator and a laser
beam control device, the spraying direction of the cold spray head can be adjusted so that sprayed
powder particle beams can be scanned on the
workbench based on the shape of a part, the laser
beam control device is installed at an emitting opening of the laser generator and used for controlling the emitting direction of
laser beams, the
laser beams and the
powder particle beams sprayed by the cold spray head are converged at one point, and the surface of the base body and the
powder particles are heated to be in a
molten state. According to the device, the part is formed by directionally spraying powder and heating and
sintering in real time, layer-by-layer powder laying and
sintering are not needed, the forming efficiency is greatly improved, the powder cannot be wasted, the forming cost is reduced, the forming quality consistency is good, the forming quality is improved, the part
sintering procedure is simplified, and the sintering efficiency is improved.
