Abstract

The invention provides a powder conveying device and method and additive manufacturing equipment, and relates to the technical field of additive manufacturing. The powder conveying device and the method and the additive manufacturing equipment aim at solving the problem that the quality of parts is reduced due to the fact that air influences powder in the powder adding process of an existing powder adding assembly. The powder conveying device comprises a powder adding assembly, a powder feeding assembly and a pressure balancing assembly, wherein the powder adding assembly is used for containing powder. When the powder conveying device is in a non-working state, the powder adding assembly, the powder feeding assembly and the pressure balancing assembly are independent of one another; the powder adding assembly is in a closed state when containing the powder; and when the powder conveying device is in a working state, the powder adding assembly communicates with the powder feeding assembly, and the pressure balancing assembly communicates with the powder adding assembly and the powder feeding assembly and is used for balancing the internal pressure of the powder adding assembly and the powder feeding assembly. The invention further provides the powder conveying method applied to the powder conveying device and additive manufacturing equipment comprising the powder conveying device.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a powder conveying device and method, and additive manufacturing equipment. Background technique [0002] During the additive manufacturing process (for example: laser printing or laser cladding), it is necessary to use the powder delivery device to provide powder to the additive manufacturing equipment. The powder conveying device generally includes a powder feeding assembly and a powder feeding assembly, wherein the powder feeding assembly is used to continuously provide powder to the powder feeding assembly, and the powder feeding assembly is used to provide powder to additive manufacturing equipment. [0003] The powder feeding assembly and the powder feeding assembly included in the powder conveying device provided by the prior art are detachably or fixedly connected together. When it is necessary to use the powder feeding assembly to add powder to the powder ...
