Problems solved by technology

This method has the following disadvantages: the zinc wire is exposed to the air, part of the melting process is lost by oxidation, the other part is lost by gasification, and the other part is blown away because the position is not fixed during the blowing process, so the utilization rate of the zinc wire is reduced. As low as about 40%, and the dust in the gold spraying process is relatively large

Abstract

The invention relates to 3D printing metal spraying equipment as well as a 3D printing device and a control method thereof. The 3D printing metal spraying equipment comprises a metal molten drop 3D printing device, and the metal molten drop 3D printing device is provided with a metal molten drop discharging opening. The 3D printing metal spraying equipment further comprises a supersonic air curtain disperser used for blowing out metal molten drops discharged from the metal molten drop discharging opening, and the supersonic air curtain disperser is arranged beside the outside of the metal molten drop discharging opening. According to the 3D printing metal spraying equipment, a metal molten drop 3D printing technology and the supersonic air curtain disperser are combined, metal molten dropsare blown out to implement metal spraying, the oxidation and gasification rate of metal melt in the process is low, and the material utilization rate is high; and even metal substances sprayed to other positions during metal spraying can be placed into the metal molten drop 3D printing device again to be melted and reused, and the equipment is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of gold spraying, in particular to a 3D printing gold spraying device, a 3D printing device and a control method thereof. Background technique [0002] The working principle of the current gold spraying machine is: the voltage carried by two zinc wires (or other metal wires) generates a current and generates heat to form an arc. The scanning movement forms the metal surface. This method has the following disadvantages: the zinc wire is exposed to the air, part of the melting process is lost by oxidation, the other part is lost by gasification, and the other part is blown away because the position is not fixed during the blowing process, so the utilization rate of the zinc wire is reduced. As low as about 40%, and the dust in the gold spraying process is relatively large. Contents of the invention [0003] The purpose of the present invention is to provide a 3D printing gold spraying device with simple an...
