Embodiment 1

[0036] combine Figure 1 to Figure 3 As shown, the present invention provides a device for preparing metal powder, which device includes a support 5, an atomizing unit 1, a powder collecting unit 2, a lifting unit 3, a conveying unit 4 and a first metal wire arranged on the conveying unit 4 6-1 and the second metal wire 6-2, the powder collection unit 2 is located under the atomization unit 1, and the two ends of the lifting unit 3 are respectively connected with the bracket 5 and the atomization unit 1 for suspending the atomization unit 1 Above the powder collection unit 2 or on the powder collection unit 2, the transmission unit 4 is connected to the bracket 5, and is used to transport the first metal wire 6-1 and the second metal wire 6-2 to the atomization unit 1, the mist The atomizing unit 1 is connected with the gas source, and is used for atomizing the first metal wire 6-1 and the second metal wire 6-2, and the first metal wire 6-1 and the second metal wire 6-2 are re...

Embodiment 2

[0051] In order to solve the above problems, the present invention also provides a method for preparing metal powder, the method comprising the following steps:

[0052] Start the lifter 3-1, and gradually lower the atomization tank 1-1;

[0053] After the atomization tank 1-1 is covered on the powder collection box 2-1, the hoist 3-1 is closed, and the atomization tank 1-1 and the powder collection box 2-1 are jointly surrounded to form a closed space;

[0054] Connect the gas source to make the atomizer 1-2 inject gas into the atomization tank 1-1;

[0055] Switch on the power supply that is connected with the first metal wire 6-1 and the second metal wire 6-2, start the wire disc 4-1 simultaneously, because the first metal wire 6-1 and the second metal wire 6-2 poles On the contrary, the metal wire at the contact point of the first metal wire 6-1 and the second metal wire 6-2 will continue to arc and melt in the atomization tank 1-1 to form molten metal, and the molten met...

Abstract

The invention relates to the technical field of 3D printing material additive manufacturing and metallurgy and provides a metal powder preparation device and method. The device comprises a support, an atomization unit, a powder collection unit, a hoisting unit, a conveying unit, a first metal wire and a second metal wire, and the first metal wire and the second metal wire are arranged on the conveying unit. The powder collection unit is located under the atomization unit. The two ends of the hoisting unit are connected with the support and the atomization unit correspondingly and used for enabling the atomization unit to be suspended on the powder collection unit or arranged on the powder collection unit in a covering mode. The conveying unit is connected with the support and used for conveying the first metal wire and the second metal wire to the atomization unit. The atomization unit is connected with an air source and used for atomizing the first metal wire and the second metal wire. The first metal wire and the second metal wire are connected with the positive pole and the negative pole of a power supply correspondingly. By means of the method, the shape and size of metal powder can be controlled easily, contamination of other materials is avoided, the purity of metal powder is improved, and the stability of ingredients of the metal powder is guaranteed.

Description

technical field [0001] The invention relates to the technical fields of 3D printing additive manufacturing and metallurgy, in particular to a device and method for preparing metal powder. Background technique [0002] Metal powder is an important branch of the material industry. Workpieces prepared from metal powder have excellent properties that other materials cannot obtain. Therefore, metal powder has broad application prospects in metallurgy, energy, electronics, medical, aerospace and other fields. With the development of 3D printing technology, the application field of metal powder has been further expanded. [0003] At present, the high-pressure gas atomization method with a crucible is mainly used in the preparation of metal powder at home and abroad. When using this method, the metal solution is in contact with the refractory material that constitutes the crucible, resulting in contamination by non-metallic inclusions, resulting in a reduction in the purity of the...
