Embodiment 1～ Embodiment 5

[0047] In order to more clearly introduce the separation method of the spherical metal powder provided by the embodiment of the present invention, the method is described in detail below in conjunction with Embodiment 1 to Embodiment 5:

Embodiment 1

[0049] Put the Ti6Al4V powder with a particle size of 30-300 μm into the powder box 1, adjust the baffle plate 2, and make the Ti6Al4V powder to be separated naturally and uniformly fall from the inclined plate 3 with an inclination angle of 15° to an aspect ratio of On the 2.5:1 conveyor belt 4, the running speed of the conveyor belt is 2m / min.

[0050] After separation, the Ti6Al4V powder collected in the first powder collection box 5 accounts for 94% of all Ti6Al4V powders to be separated, and its sphericity is ≥ 90%; the Ti6Al4V powder collected in the second powder collection box 6 accounts for 5%; the third powder The Ti6Al4V powder collected in the collection box 7 accounts for 1%.

Embodiment 2

[0052] Put the TiAl4822 powder to be separated with a particle size of 30-300 μm into the powder box 1, and adjust the baffle plate 2 so that the TiAl4822 powder to be separated naturally and uniformly falls from the inclined plate 3 with an inclination angle of 45° to the length and width at 50 g / s. On the conveyor belt 4 with a ratio of 2:1, the conveyor belt runs at a speed of 2.55 m / min.

[0053] After separation, the TiAl4822 powder collected in the first powder collection box 5 accounts for 96% of all TiAl4822 powders to be separated, and its sphericity is ≥ 90%; the TiAl4822 powder collected in the second powder collection box 6 accounts for 3%; the third powder The TiAl4822 powder collected in the collection box 7 accounts for 1%.

Abstract

The invention discloses a method and device for separating spherical metal powder, and relates to the technical field of powder screening. The method and device are used for solving the problems thatin the prior art, spherical metal powder separation is discontinuous, efficiency is low, and the separation function is single. The method comprises the steps that to-be-separated metal powder is placed into a powder box and slides down onto a conveying belt along an inclined plate, wherein an included angle ranging from 5 degrees to 45 degrees is formed by the inclined plate and the powder box; and the conveying belt moves at a constant speed to drive the to-be-separated metal powder sliding down onto the conveying belt, and the to-be-separated metal powder sequentially falls into a first powder collection box, a second powder collection box and a third powder collection box according to degrees of sphericity.

Description

technical field [0001] The invention relates to the technical field of powder screening, and more specifically relates to a separation method and device for spherical metal powder. Background technique [0002] As a technology that has attracted much attention, additive manufacturing technology has been vigorously developed in aerospace, automobile, biomedicine and other industries, and has become an important force to promote the transformation and upgrading of traditional manufacturing industries. However, powder consumables are still one of the important factors restricting the large-scale application of this technology. Due to its good fluidity, spherical metal powder can be laid into a thin layer, thereby improving the dimensional accuracy and surface quality of the part, and the part can also obtain high-density and uniform structure. It is the preferred raw material shape for metal additive manufacturing. However, during the preparation of spherical metal powders, sp...
