Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, specifically a dual wire feeding adjustment device for experimental niobium-titanium alloy TIG additive manufacturing. Background Technology
[0002] Arc additive manufacturing is a directional energy deposition (DED) technology that deposits metallic materials in the form of powder or wire using nozzles mounted on a multi-axis arm. An electric arc serves as the heat source, melting the material and then building the part layer by layer. Compared to laser energy deposition, arc additive manufacturing offers advantages such as higher forming efficiency, lower equipment costs, and flexible manufacturing.
[0003] Niobium-titanium alloys are alloys composed of metallic niobium and metallic titanium. Industrially produced niobium-titanium alloys typically contain 20%–60% titanium (by mass), with the most typical containing 66% titanium [approximately 50% by mass]. They are important alloy-type superconducting materials with a superconducting transition temperature of 8–10 K. Adding other elements can further improve their superconducting properties. Titanium exists in a solid solution state within the alloy.
[0004] In additive manufacturing, the alloy composition of niobium-titanium alloys needs to be adjusted according to requirements. A dual-feed system allows for independent control of the niobium and titanium wire ratios to meet specific needs. The multi-degree-of-freedom adjustment design further enables precise control of parameters such as wire feed angle, distance, and offset, improving the forming process.
[0005] Therefore, we propose a dual wire feeding adjustment device for experimental niobium-titanium alloy TIG additive manufacturing. In niobium-titanium alloy additive manufacturing, titanium wire often melts first and niobium wire melts later. To obtain a certain proportion of high-quality alloy, it is necessary to precisely control parameters such as the wire feed angle, distance, and offset. This device has a multi-degree-of-freedom adjustment function, which can solve the above problems. Summary of the Invention

[0008] One approach is to install motors at both ends of the top surface of the horizontal plate to drive the rotating rod to rotate. Another approach is to install a handwheel on the top surface of the rotating rod to drive it to rotate. Both methods can drive the rotating block and the lead screw to rotate, thereby adjusting the angle of the lead screw.

[0013] This invention provides a dual wire feeding adjustment device for experimental TIG additive manufacturing of niobium-titanium alloy. It has the following advantages:
[0014] 1. The dual wire feeding adjustment device used in this experiment for TIG additive manufacturing of niobium-titanium alloys works by moving niobium and titanium wires through two wire feeding rods towards the welding end of the TIG welding torch, respectively. The TIG welding torch then performs additive manufacturing on the niobium and titanium wires. The output end of the fourth hydraulic rod pushes the U-shaped block to move, which in turn causes the wire feeding rod at its bottom to tilt vertically, so as to adjust the tilt angle of the niobium and titanium wires in the vertical direction. By rotating the rotating rod to drive the rotating block to rotate, the horizontal angle of the corresponding wire feeding rod can be adjusted. This achieves multi-degree-of-freedom adjustment of wire feeding, which can precisely control wire feeding and meet various wire feeding adjustment requirements in niobium-titanium alloy additive manufacturing.

The clamping assembly and TIG welding torch were moved by the TIG welding torch Y-axis adjuster, which then adjusted the welding point of the TIG welding torch. The second hydraulic rod pushed the third moving plate to move back and forth, and the third hydraulic rod pushed the fourth moving plate to move up and down, which could adjust the position of the wire feeding rod so as to align the TIG welding torch with the niobium wire and titanium wire passing through the inside of the wire feeding rod.

During use, the niobium wire and titanium wire are respectively moved through the two wire feeding rods 8 and towards the welding end near the TIG welding torch 3. Then, the TIG welding torch 3 performs additive manufacturing on the niobium and titanium wires. During this process, the output end of the fourth hydraulic rod 73 is activated to push the U-shaped block 74 to move, which in turn causes the U-shaped block 74 to tilt the wire feeding rod 8 at its bottom in the vertical direction, facilitating the adjustment of the tilt angle of the niobium and titanium wires in the vertical direction. This is achieved by rotating the rotating rod. 77 drives the rotating block 76 to rotate, which can adjust the horizontal angle of the corresponding wire feeding rod 8. During the adjustment process, the first hydraulic rod 23 is activated to push the first moving plate 22 to move on the surface of the first fixed plate 21, so as to drive the clamping assembly 4 and the TIG welding torch 3 to move.
