Description

Technical Field

[0001] The utility model relates to the technical field of additive manufacturing equipment, in particular to a vibration plate type ultrasonic assisted and water cooling device for wire arc additive manufacturing of titanium alloy wire. Background Art

[0002] Titanium alloy is widely used in the fields of aerospace, shipbuilding, etc. due to its high specific strength, excellent fracture toughness and good corrosion resistance. Compared with powder bed additive manufacturing using laser and electron beam as heat sources, wire arc additive manufacturing (WAAM) technology has additional advantages such as high material utilization rate, high deposition efficiency, low equipment investment and operation cost, making it suitable for manufacturing large-size titanium alloy structural parts in the fields of aerospace and shipbuilding. However, due to the large temperature gradient of the molten pool and multiple thermal cycles during the manufacturing process, a large number of epitaxially grown β columnar grains and coarse acicular α phases are generated in the titanium alloy components during the manufacturing process. This non-uniform microstructure will lead to anisotropy of the mechanical properties of the material. At the same time, it is easy to be polluted by environmental gases during the arc additive manufacturing process, and porosity defects are likely to occur inside the deposited components. Therefore, how to refine the microstructure of titanium alloy components manufactured by arc additive manufacturing and eliminate porosity defects is the main problem faced in its current development.

[0003] The methods for refining the microstructure of titanium alloy manufactured by arc additive manufacturing and eliminating porosity defects can be mainly divided into two categories: post-treatment heat treatment and in-situ control. Post-treatment heat treatment is to process the arc additive manufactured titanium alloy components completed by a suitable heat treatment process to achieve the purpose of refining the structure and improving the performance. In-situ control is to control the structure of titanium alloy components and eliminate their defects by means of rolling, ultrasonic impact, active cooling or adding alloy elements during the additive manufacturing process.

[0004] One of the current technology optimization methods is to adopt the solution aging treatment method, which improves the uniformity of the microstructure of arc additive manufactured titanium alloy and reduces the anisotropy of the mechanical properties of the components. The second current technology optimization method adopts the combination of heat treatment and hot isostatic pressing, which refines the grains of arc additive manufactured titanium alloy components and eliminates pores, achieving the best balance between the strength and ductility of the components. However, the above two methods only support the treatment of the components after the arc additive manufacturing components are processed, reducing the production efficiency of the arc additive manufacturing components. Moreover, the heat treatment of titanium alloy needs to be carried out in a vacuum or inert gas, increasing the process difficulty and production cost.

[0005] The third current technology optimization method is to refine the microstructure of arc additive manufactured titanium alloy components and improve their mechanical properties through the rolling process, but the rolling method will be greatly limited when facing components with relatively complex structures.

[0006] The fourth method for optimizing the current technology proposes a method for refining the α-phase and β columnar crystals of titanium alloy components in wire arc additive manufacturing by adding a trace amount of boron element. However, it is difficult to precisely control the addition amount of boron element by this method, and boron element has an adverse effect on the high-temperature properties of titanium alloy.

[0007] The fifth method for optimizing the current technology uses a single ultrasonic impact gun to apply ultrasonic vibration to achieve the purpose of refining grains and reducing pores. However, since this method uses an impact gun as the ultrasonic source, the vibration power is small and the action area is limited, resulting in poor effect of ultrasonic vibration on the molten pool, and different vibration effects on molten pools at different positions, and the effect of refining the microstructure and reducing pore defects is not good.

[0008] In summary, the microstructure of titanium alloy manufactured by wire arc additive manufacturing (wire arc additive manufacturing of titanium alloy) is coarse, and pores are likely to be generated in the weld beads. By post-heat treating the additive manufactured components or performing in-situ regulation during the additive manufacturing process, it is possible to help refine the microstructure of the additive manufactured components, reduce pore defects, improve the density of the wire arc additive manufactured components, and improve the microstructure and mechanical properties of the formed parts. However, methods such as post-heat treatment, rolling, adding alloy elements, and ultrasonic vibration of the impact gun have problems such as low efficiency, low applicability, difficulty in precise regulation, and poor refining effect. Therefore, the problem to be solved by the patent solution of this patent is how to refine the microstructure of titanium alloy in wire arc additive manufacturing, reduce the pore defects in the deposition layer, and obtain wire arc additive manufactured titanium alloy components with uniform organization, dense structure, and good forming according to the characteristics of wire arc additive manufacturing of titanium alloy and the characteristics of the forming process.

[0009] In view of the deficiencies of the above existing technical solutions, the patent solution of the present utility model proposes a vibrating plate type ultrasonic assisted and water cooling device for wire arc additive manufacturing of titanium alloy. The vibrating plate with multiple oscillators arranged in a distributed manner is used as the ultrasonic source to act on the entire forming substrate, avoiding the problems of small vibration power and limited action range of the ultrasonic vibration gun; combined with the water cooling plate to reduce the heat accumulation at the vibrating plate during the additive manufacturing process and protect the vibrating plate to work for a long time. This patent solution has the advantages of compact structure, high integration, remarkable effect, and strong applicability, and can provide strong technical support and process basis for realizing the refinement of the microstructure of wire arc additive manufactured titanium alloy and reducing pore defects.

The end face of the ceramic nozzle is 6 mm away from the substrate, and the tungsten electrode extends 1 mm out of the end face of the ceramic nozzle. The wire feeding copper nozzle 2-2 forms an angle of 30° with the horizontal plane to ensure that the wire feeding copper nozzle will not contact the titanium alloy substrate 3-1 during the arc additive manufacturing process.
