Abstract

The invention discloses a metal powder processing system for 3D printing equipment. The metal powder processing system comprises a powder cylinder, a powder feeding device and a powder spreading device, wherein the powder cylinder, the powder feeding device and the powder spreading device sequentially communicate through powder feeding pipes. According to the metal powder processing system for the3D printing equipment, the structure is simple, the use is convenient, (metal) powder in the powder cylinder can be stably and quantitatively conveyed to the powder spreading device through the powder feeding device, and then the stable and efficient powder spreading is carried out by the powder spreading device, so that the automatic and accurate feeding are realized, and the printing forming efficiency of the 3D printing equipment and the quality of printed finished products are improved; the powder cylinder solves the technical problems that in the prior art, the operation steps for the micro-adjustment of a sealing ring are very complicated, and the sealing performance of the periphery of the sealing ring after the micro-adjustment cannot be effectively guaranteed to be consistent; and the powder feeding device can feed the powder quantitatively as required, so that not only is the powder feeding precision improved, but also the waste is avoided, and the printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a metal powder processing system for 3D printing equipment. Background technique [0002] Additive manufacturing, commonly known as 3D printing, is a type of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Compared with the traditional processing technology, its processing cost is low, the material utilization rate is high, and the processing speed is fast. [0003] According to the patent number CN207840130U, it is called a powder cylinder with sealing adjustment function and laser 3D printing equipment, including a cylinder body, a cover plate, a felt, a piston, a spring plunger and a sealing ring; the sealing ring is arranged at one end of the piston on the surface and close to the inner wall of the cylinder; it has the ad...
