Conveying device for mixed metal powder

Abstract

The invention discloses a conveying device for mixed metal powder and relates to the field of 3D printing. The conveying device for the mixed metal powder comprises a first funnel and a second funnelused for containing the metal powder; the lower end of the first funnel and the lower end of the second funnel are communicated with a first feeding pipe and a second feeding pipe correspondingly; oneend of the first feeding pipe and one end of the second feeding pipe are provide with a first driving system and a second driving system correspondingly; the first feeding pipe and the second feedingpipe are internally provided with a first piston and a second piston correspondingly; the first driving system and the second driving system are connected with the first piston and the second pistoncorrespondingly; the other end of the first feeding pipe and the other end of the second feeding pipe are provided with a first discharging port and a second discharging port correspondingly; the first discharging port and the second discharging port are arranged in opposite directions, and are communicated through a powder leaking pipeline; a powder leaking mechanism is arranged at the outlet position of the powder leaking pipeline; and a plurality of grooves sunken towards the position of the circle center of a rolling wheel are circumferentially distributed in the periphery of the rolling wheel. According to the conveying device for the mixed metal powder, the powder is better saved, and stability of the whole process is guaranteed.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a conveying device for metal mixed powder. Background technique [0002] In recent years, 3D printing has developed rapidly, and with the continuous expansion of application fields, it has attracted more and more attention from all parties. With the promulgation of various favorable policies of the country, additive manufacturing has also been favored by capital. In the foreseeable future, the field of additive manufacturing is bound to usher in explosive growth. Additive manufacturing is an advanced digital manufacturing technology, which can quickly manufacture parts with complex geometric shapes based on CAD models. Additive manufacturing technology integrates modern scientific and technological achievements such as CAD technology, numerical control technology, laser technology and material technology, and is the development direction of advanced manufacturing technology in the fut...

Problems solved by technology

[0004] At present, there are two kinds of feeding devices for selective laser melting technology, one is powder feeding by material cylinder, and the other is feeding by rotating drum, but neither can achieve the practical effect of accurate feeding and saving metal powder as much as possible , and most of the metal powders of one material are used at present. In the actual molding process in the future, metal powders of mixed materials may be involved. The current two feeding devices need to add a powder mixing and stirring device before feeding. , will occupy a huge equipment space, therefore, there is a need for a conveying device that improves the utilization rate of the powder, ensures a stable and accurate conveying process, and can realize simultaneous feeding of multiple groups of powders
