Abstract

The present invention is a plasma arc dual power supply and dual heating wire additive manufacturing method and device for robots. The device includes a heating wire heating power supply I, a heating wire heating power supply II, and a dual-wire heating coordination control module. The method sends two cold wires through the double wire feeding device, and uses the heating power of the double wire heating device to heat the ends of the wires to realize the feeding of the double hot wires; the control cabinet communicates with the double wire feeding device to control the wire feeding The machine feeds the wire synchronously; the control cabinet controls the heating power supply at the same time, controls the time and temperature of the heating wire, and realizes the pulsating hot wire feeding; the welding machine is controlled by the robot control cabinet to realize the synchronization of wire feeding, heating and arc combustion . When the device is used for plasma arc double-hot wire additive manufacturing, the feeding speed of the wire is increased by more than 1.5 times under the same process parameters, which can realize additive manufacturing with higher cladding efficiency.
