Abstract

The invention discloses a packaging device for reactive metal powder for 3D printing and belongs to the technical field of powder packaging. The device comprises a material collection tank, a materialtank support, a feeding ball valve, a glove box, a stainless steel pipe, an exhaust valve, a gas inlet valve and the like. The material collection tank stands upside down on the material tank support. A tank opening is connected with the feeding ball valve. The lower end of the feeding ball valve is connected with the stainless steel pipe. The stainless steel pipe communicates with the interior of the glove box. When the packaging device is used, firstly, the device is mounted, the glove box is opened, and a packaging barrel is put into the glove box; in the vacuum extraction and argon gas charging process, exhaust and inflation of the glove box are achieved through the exhaust valve and the gas inlet valve; powder feeding is conducted through the feeding ball valve (3); and finally, opening sealing is conducted through an electro-magnetic induction opening sealer (8). The packaging device has the beneficial effects that good sealing performance is achieved; and the problems that powder absorbs moisture and is oxygenated and contaminated by impurities due to manual powder feeding are avoided.

Description

technical field [0001] The invention belongs to the technical field of powder packaging, in particular to a packaging device for active metal powder for 3D printing. Background technique [0002] Additive Manufacturing (AM), also known as 3D printing, uses the three-dimensional model data of computer-aided design (CAD) to accumulate materials layer by layer to manufacture physical parts. It is known as the intelligent manufacturing technology that triggered the "third industrial revolution". The raw materials used in additive manufacturing need to have higher sphericity, better fluidity, more concentrated particle size distribution and lower oxygen content. Therefore, under the above requirements, the powder directly produced by the atomizing powder making furnace must undergo strict treatment to obtain qualified metal powder that meets the requirements of 3D printing. [0003] Through the investigation of metal powder packaging at home and abroad, it is found that the powd...
