Abstract

The invention discloses a two-way powder laying device for additive manufacturing. The two-way powder laying device for additive manufacturing comprises a working table, a powder laying mechanism anda first driving device, wherein the powder laying mechanism is slidably installed on the working table in a linear reciprocating left and right mode, and the first driving device is installed on the working table and used for driving the powder laying mechanism to slide. The powder laying mechanism comprises a scraper installation seat, a scraper and two powder laying channels, the reciprocating sliding scraper installation seat is driven by the first driving device, the scraper is installed at the bottom of the scraper installation seat, and the two powder laying channels are arranged on thescraper installation seat and located on the left side and the right side of the scraper. The two-way powder laying device for additive manufacturing can lay powder in both directions, empty stroke isavoided, two-way stroke is effectively used for performing the powder laying operation, and the efficiency of powder laying is improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, in particular to a two-way powder spreading device for additive manufacturing. Background technique [0002] Based on the process characteristics of layer-by-layer processing of additive manufacturing equipment, before each scanning process, a new layer of powder must be spread for sintering or melting; large-scale additive manufacturing equipment has a large molding area, and the required span of the powder-spreading scraper structure Large and long stroke, it is bound to have higher requirements on the structural rigidity and work efficiency of the scraper device; in the prior art, the material is spread and scraped once in one cycle of the powder spreading device, which will easily lead to empty travel and reduce work efficiency . [0003] Therefore, in order to solve the above problems, a two-way powder spreading device for additive manufacturing is needed, which can realize p...
