Abstract

The invention discloses a powder return pipe device of metal 3D printing equipment. The device structurally comprises a first powder loading box, handles, a base, a shell, a display screen and a second powder loading box; the first powder loading box and the second powder loading box are mounted on the base in a form of symmetrical structures about the display screen, and are fixedly connected with the base; the shell is connected with the first powder loading box and the second powder loading box; the two handles are provided, and are correspondingly mounted on the first powder loading box and the second powder loading box; the display screen is mounted at the top of a panel on the front surface of the shell; and the display panel and the panel on the front surface of the shell are located on one horizontal face. The handles are controlled to drive a driving rod to push movement of a rolling ball to realize powder pavement; and when the rolling ball is pulled back by a spring, redundant powder is taken back to prevent wastes.

Description

technical field [0001] The invention is a powder return pipeline device for metal 3D printing equipment, which belongs to the field of powder return pipeline devices. Background technique [0002] Metal 3D printing equipment mainly includes bottom powder feeding-one-way powder spreading, and upper powder feeding-two-way powder spreading. The two-way powder spreading mode is twice as fast as the one-way powder spreading mode in this link, so it is more suitable. To meet the needs of the market and customers, metal 3D printing equipment needs to use a powder scraper to recycle the excess powder after each layer of powder is sintered by the laser. After the printing task is completed, the excess powder also needs to be recovered. The barrel is located at the front and rear of the metal 3D printing equipment, that is, the front and rear two pipelines collect the recovered powder at the same time, which makes the metal 3D printing equipment only open the back door to replace the ...
