Multifunctional quantitative powder supplying and spreading device

Abstract

The invention belongs to the technical field of additive manufacturing, and particularly relates to a multifunctional quantitative powder supplying and spreading device. The multifunctional quantitative powder supplying and spreading device comprises a workbench, a forming bin, two powder supplying device bodies, a powder spreading device body and a driving device, wherein the workbench is of a hollow cuboid structure, the powder spreading device body, the driving device and the powder supplying device bodies are all arranged in the workbench, and an operation window is formed in the side wallof the workbench. The forming bin is formed below the workbench, a first powder supplying bin and a second powder supplying bin are arranged at the left and right sides of the upper position of the platform, and the powder spreading device body is arranged on the platform, and is connected with the driving device. By means of the multifunctional quantitative powder supplying and spreading device,powder can be quantitatively spread and supplied twice within a single cycle, the time is saved, an idle stroke is avoided, the working efficiency is improved in the printing process, and a control mechanism is simple, compact and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a multifunctional quantitative powder supply and quantitative powder spreading device. Background technique [0002] Based on the process characteristics of additive manufacturing layer-by-layer forming, before each laser scanning process, a new layer of powder needs to be re-spread for melting and forming. After completion, the excess powder is removed, and the parts are polished and dried to complete the whole Processing and manufacturing of parts; for large-scale additive manufacturing equipment with a large forming area, the required powder spreading scraper structure has a large span and long stroke, which requires higher requirements for the working efficiency of the scraper device. In one cycle of the powder spreading device One-time powder spreading and scraping powder can easily cause empty strokes and low work efficiency; with the development ...
