Abstract

The invention discloses a powder laying device for rapid forming manufacturing. The device comprises a powder laying compaction system and a forming system, and is characterized in that the powder laying compaction system comprises a scraping plate, hoppers arranged on the two sides of the scraping plate, baffles arranged at the lower ends of the hoppers, discharging motors driving the baffles to open the hoppers for discharging, lifting driving devices arranged on the hoppers and pressing roller components arranged at the output ends of the lifting driving devices; each pressing roller component comprises a pressing roller seat, a pressing roller and a pressing roller driving motor, wherein the pressing rollers are arranged on the pressing roller seats; and the forming system comprises a forming cylinder and a jacking mechanism arranged in the forming cylinder, and the pressing rollers act on the upper surfaces of the forming cylinders. Compared with the prior art, the powder laying device has the beneficial effects of being uniform in powder laying thickness, high in pressing compactness of the forming part pressing rollers, rapid in forming and the like.

Description

technical field [0001] The invention relates to a powder laying device, in particular to a powder laying device for rapid prototyping. Background technique [0002] The main technical means of rapid prototyping manufacturing is 3D printing technology. Many of 3D printing technologies use powder as raw material, stacked in layers, and finally formed. This new type of rapid manufacturing technology can directly obtain molded parts of any shape without being affected by the complexity of the molded parts, providing a higher degree of freedom for the design, and compared with the previous processing technology, its processing cost is low, and the processing The speed is fast, especially suitable for experimental verification and small batch production in the early stage of research and development, and has broad application prospects. [0003] At this stage, all kinds of rapid manufacturing technologies using powder spreading devices have the following similar problems: [000...
