Problems solved by technology

This method ignores the influence of factors such as high temperature environment and molten pool splash on the camera monitoring system during the additive manufacturing process
In addition, due to the small diameter of the wire, the sensitivity of the camera system will be reduced, and it will even be difficult to monitor.
[0005] The above problems make it difficult to control the forming quality of laser fuse additive in the actual application process, and ultimately lead to the inability to effectively complete the entire laser fuse additive manufacturing process within a reasonable time, which seriously restricts the development of laser fuse additive technology

Abstract

The invention discloses ultrasonic-assisted multi-beam laser wire-melting type additive manufacturing equipment. The equipment comprises a laser device, a wire feeding mechanism, a base plate, a wireguide head, an electromagnetic ultrasonic generator, an electromagnetic ultrasonic probe, a controller and a protective gas protection box, wherein the laser device comprises a laser light source, anoptical fiber and a laser head, the laser light source is connected with the laser head through the optical fiber, the electromagnetic ultrasonic generator is arranged at an inlet of the wire guide head, the electromagnetic ultrasonic probe is arranged on the base plate, and is used for receiving a vibration signal of an accumulated body and transmitting the vibration signal to the controller so that monitoring of a droplet transfer state in the additive manufacturing process can be realized, and the base plate, the wire guide head, the electromagnetic ultrasonic generator and the electromagnetic ultrasonic probe are all located in the protective gas protection box. According to the equipment, the flexibility of the additive manufacturing process can be greatly improved so that the accumulated layers are not prone to collapse, then the mechanical property of the accumulated body can be improved, the deformation can be inhibited, and the speed of the additive process can be increased.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and more particularly relates to an ultrasonic-assisted multi-beam laser fuse additive manufacturing equipment and method. Background technique [0002] Additive manufacturing technology overcomes the large waste of raw materials caused by traditional "material removal" manufacturing, and at the same time has the advantages of rapid prototyping, grain refinement, and uniform organization. It has become the first choice for rapid prototyping technology of complex structural parts. Compared with other metal additive manufacturing technologies, laser fuse additive technology uses high-energy-density laser as the heat source, which has the characteristics of high forming efficiency, and can heat and melt the fed wire according to the predetermined processing path. Layer accumulation, and finally realize the near net shape direct manufacturing of metal parts. This technology is especia...
