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 present invention relates to a 3D printing gold spraying device and its 3D printing device and control method. The 3D printing gold spraying device includes a metal droplet 3D printing device, the metal droplet 3D printing device is provided with a metal droplet output port, and also includes a The supersonic air curtain disperser is used to blow out the metal droplets coming out of the metal droplet output port, and the supersonic air curtain disperser is arranged outside the metal droplet output port. This 3D printing gold spraying equipment uses the combination of metal molten droplet 3D printing technology and supersonic air curtain disperser to blow out metal molten droplets to realize gold spraying. In this process, the oxidation and gasification rate of metal molten material is low, and the material utilization rate is high. ; Even the metal material sprayed on other positions during gold spraying can be put into the metal droplet 3D printing device to be melted and reused, which 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...
