Abstract

The invention discloses a selective laser melting powder sending and laying device used for compounding of different types of powder. The selective laser melting powder sending and laying device comprises a worktable, a forming cylinder, a powder spraying device and a powder laying device. The upper surface of the forming cylinder is arranged on the worktable. The powder spraying device and the powder laying device are arranged on the two sides of the forming cylinder. The powder spraying device is characterized in that powder spraying electric guide rails, a support, a nozzle electric guide rail and a nozzle are included; the nozzle is arranged on the nozzle electric guide rail; the nozzle electric guide rail is arranged on the powder spraying electric guide rails through the support; and the powder spraying electric guide rails are fixed to the worktable. The powder laying device comprises a powder hopper, a powder scraping electric guide rail and a supporting frame; the powder hopper is arranged on the powder scraping electric guide rail through the supporting frame; and the powder scraping electric guide rail is fixed to the worktable. According to the selective laser melting powder sending and laying device used for compounding of different types of powder, the selective laser melting technology and the laser cladding coaxial powder sending technology are combined, and the purposes of effectively recovering powder during compound additive manufacturing of gradient materials and forming parts with complex gradients in any direction are achieved.

Description

technical field [0001] The invention relates to the field of additive manufacturing, in particular to an area-selective laser melting powder feeding and spreading device for composite use of different powders. Background technique [0002] Gradient material is a new type of functional material that appeared in the 1980s. It has many excellent properties such as high temperature resistance and wear resistance. Due to its excellent structure and performance, it has become a research hotspot in the field of materials. At present, the preparation methods of gradient materials that have been developed mainly include: chemical vapor deposition method, physical evaporation method, plasma spraying method, particle gradient arrangement method, self-propagating high temperature synthesis method, direct liquid film formation method and thin film infiltration molding method, etc. These methods are difficult to process complex precision gradient parts.
