Abstract

The invention relates to a powder cooling device which comprises a positioning device, a pressing device, a cooling device and a control terminal. The positioning device is used for fixing and storinga powder bag; the pressing device is arranged at the upper end of the positioning device and can stretch into the positioning device so as to press the fixed powder bag; the cooling device communicates into the positioning device and is fed with an inert gas so as to cool the powder bag; and the control terminal is electrically connected with the positioning device, the pressing device and the cooling device. The powder cooling device provided by the invention can be used for quickly sizing and cooling the overall hot processing powder, so that the occurrence of a quality problem of product deformation is reduced, the production efficiency is greatly improved, and the powder cooling device has an anti-blockage function.

Description

technical field [0001] The invention relates to the technical fields of powder thermal fusion processing such as selective laser powder sintering (SLS) and multi-jet fusion (MJF), and in particular to a powder cooling device. Background technique [0002] Selective laser powder sintering (SLS) technology uses infrared lasers as energy sources, and most of the modeling materials used are powder materials. During processing, the powder is first preheated to a temperature slightly lower than its melting point, and then the powder is flattened under the action of the scraping cylinder; the laser beam is selectively sintered according to the information of the layered section under computer control, and one layer After the completion, the next layer of sintering is carried out. After all the sintering is completed, the excess powder is removed, and then a sintered part can be obtained. After forming, the overall temperature is high. If the product cannot be cooled and shaped qui...
