Description

Technical Field

[0001] This utility model relates to the field of titanium alloy welding wire technology, specifically to a winding double wire preparation device for titanium-aluminum alloy additive manufacturing. Background Technology

[0002] Arc additive manufacturing is a directional energy deposition (DED) technology that uses nozzles mounted on a multi-axis arm to deposit metallic materials in the form of powder or wire. An electric arc acts as a heat source to melt the material, which is then used to build parts layer by layer.

[0003] Titanium-aluminum alloys are mainly composed of titanium (Ti) and aluminum (Al). A common example is the γ-TiAl alloy, which contains 48% aluminum and 52% titanium, forming a microstructure dominated by the γ phase (TiAl). This microstructure has a face-centered cubic (FCC) crystal structure, giving the material excellent high-temperature creep resistance and oxidation resistance. The alloy may contain small amounts of other elements such as vanadium (V), chromium (Cr), and molybdenum (Mo). These elements further optimize the alloy's performance by affecting the stability of the phase structure. Additive manufacturing of titanium-aluminum alloys often uses dual-wire TIG welding. However, when the welding wire is fed from both sides, poor fusion can easily occur, affecting the alloy's performance.

[0004] Therefore, we propose a twin-wire winding fabrication device for titanium-aluminum alloy additive manufacturing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a winding dual-wire preparation device for titanium-aluminum alloy additive manufacturing, which solves the problem that existing devices are unable to efficiently wind and prepare aluminum and titanium wires according to requirements.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a winding double wire preparation device for titanium-aluminum alloy additive manufacturing, comprising a worktable and four sets of support legs on its bottom side, wherein a welding wire tray mechanism, a welding wire limiting mechanism and a welding wire driving mechanism are arranged sequentially from left to right on the top of the worktable, and a controller for controlling it is also fixedly installed on the top of the worktable.

[0007] The welding wire tray mechanism is wound with aluminum wire and titanium wire. The welding wire limiting mechanism has wire holes. The main body of the welding wire driving mechanism is a drive frame. A drive motor is fixedly installed on the outer wall of the drive frame. A turntable is fixedly installed at the output end of the drive motor. A welding wire clamping mechanism that clamps the ends of the aluminum wire and titanium wire is fixedly installed on the turntable.

[0008] As a preferred embodiment of the present invention, the welding wire clamping mechanism includes a base frame and a pressure frame on its top side, and two sets of lower wire grooves and upper wire grooves in opposite positions are provided between the top side of the base frame and the bottom side of the pressure frame.

[0009] The design of the lower and upper wire grooves facilitates the pressing of the top ends of aluminum and titanium wires into them, ensuring the limiting effect and the subsequent spiral winding effect.

[0010] As a preferred embodiment of this utility model, a lead screw shaft is fixedly connected to the base frame via a bearing, a bearing ring fitted onto the lead screw shaft is mounted on the pressure frame, and a lead screw sleeve is fixedly installed at the top of the lead screw shaft.

[0011] The lead screw shaft is designed to facilitate the adjustment of the position of the pressure frame in conjunction with the bearing ring, thereby pressing and clamping the ends of the aluminum and titanium wires to ensure the limiting effect.

[0012] As a preferred embodiment of this utility model, the rear wall of the base frame of the welding wire clamping mechanism is fixedly installed on the turntable, and a column rod is fixedly installed on the top of the base frame, and the pressure frame is provided with a rod hole for rotating and fitting onto the column rod.

[0013] The design of the column rod and rod hole facilitates the sliding of the pressure frame on it, ensuring stability during adjustment and clamping.

[0014] As a preferred embodiment of the present utility model, the main body of the welding wire tray mechanism is a tray base, the two walls of the tray base are equipped with bearing trays, a rotating drum is fixedly installed at the center of the outer wall of the bearing tray, and aluminum wire and titanium wire are respectively wound on the outer walls of the left and right sets of rotating drums.

[0015] The wire tray mechanism facilitates the pre-winding of aluminum and titanium wires.

[0016] As a preferred embodiment of the present invention, the main body of the welding wire limiting mechanism is a T-shaped limiting frame. The top of the limiting frame is provided with a threaded groove, which is connected to the wire hole therein. A locking knob is threaded in the threaded groove, and the aluminum wire and titanium wire on the rear side of the welding wire limiting mechanism are wound together as a winding wire.

[0017] The wire limiting mechanism facilitates the limiting of aluminum and titanium wires of different specifications, ensuring the preparation effect of subsequent winding.

[0018] This invention provides a device for preparing twin-wire windings for titanium-aluminum alloy additive manufacturing. It offers the following advantages:

[0019] This twin-wire winding preparation device for titanium-aluminum alloy additive manufacturing, through the arrangement of various components on the worktable, can guide aluminum and titanium wires using a wire limiting mechanism. The wire driving mechanism drives the rotation of the wire clamping mechanism to wind the aluminum and titanium wires into a winding wire. Thus, by using twin-wire winding, aluminum and titanium wires are mechanically wound into a single winding wire for filling, which can effectively improve the fusion effect, enhance material strength, and improve the integration performance of arc additive parts. It solves the problem that existing devices are unable to efficiently wind and prepare aluminum and titanium wires according to requirements. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5This utility model provides a technical solution: a twin-wire winding preparation device for titanium-aluminum alloy additive manufacturing, including a worktable 1 and four sets of support legs 2 supporting it from the bottom. The top of the worktable 1 is provided with a wire tray mechanism 3, a wire limiting mechanism 4 and a wire driving mechanism 5 from left to right. A controller 6 for controlling the worktable 1 is also fixedly installed on the top of the worktable 1. The wire tray mechanism 3 is wound with aluminum wire 7 and titanium wire 8. The wire limiting mechanism 4 has wire holes. The main body of the wire driving mechanism 5 is a drive frame 51. A drive motor 52 is fixedly installed on the outer wall of the drive frame 51. A turntable 53 is fixedly installed at the output end of the drive motor 52. A wire clamping mechanism 10 clamping the ends of the aluminum wire 7 and titanium wire 8 is fixedly installed on the turntable 53.

[0028] The twin-wire winding preparation device for titanium-aluminum alloy additive manufacturing, through the arrangement of various components on the worktable 1, can guide the aluminum wire 7 and titanium wire 8 using the welding wire limiting mechanism 4. The welding wire driving mechanism 5 drives the rotation of the welding wire clamping mechanism 10 to wind the aluminum wire 7 and titanium wire 8 into a winding wire 9. Thus, by using twin-wire winding, the aluminum wire 7 and titanium wire 8 are mechanically wound together into a single winding wire 9 for filling. This can effectively improve the fusion effect, enhance the material strength, and improve the integration performance of arc additive manufacturing parts. It solves the problem that existing devices are unable to efficiently wind and prepare aluminum wire 7 and titanium wire 8 according to requirements.

[0029] Example 2:

[0030] The welding wire clamping mechanism 10 includes a base frame 101 and a pressure frame 102 on its top side. Two sets of lower wire grooves 103 and upper wire grooves 104 are provided between the top side of the base frame 101 and the bottom side of the pressure frame 102. The lower wire grooves 103 and upper wire grooves 104 are provided to press the top ends of aluminum wire 7 and titanium wire 8 into them, ensuring the limiting effect and the subsequent spiral winding effect.

[0031] A lead screw shaft 107 is fixedly connected to the base frame 101 via bearings. A bearing ring 109, which is fitted onto the lead screw shaft 107, is mounted on the pressure frame 102. A lead screw sleeve 108 is fixedly installed at the top of the lead screw shaft 107. The lead screw shaft 107 is designed to facilitate the adjustment of the position of the pressure frame 102 in conjunction with the bearing ring 109, thereby pressing and clamping the ends of the aluminum wire 7 and titanium wire 8 to ensure a limiting effect.

[0032] In the welding wire clamping mechanism 10, the rear wall of the base frame 101 is fixedly installed on the turntable 53, and the top of the base frame 101 is fixedly installed with a column rod 106. The pressure frame 102 is provided with a rod hole 105 that is rotatably fitted onto the column rod 106. The column rod 106 and the rod hole 105 are designed to facilitate the pressure frame 102 to slide up and down on it, ensuring stability during clamping and adjustment.

[0033] The main body of the welding wire tray mechanism 3 is a tray base 31. Bearing trays 32 are mounted on the two walls of the tray base 31. A rotating drum 33 is fixedly installed at the center of the outer wall of the bearing tray 32. Aluminum wire 7 and titanium wire 8 are wound on the outer walls of the left and right sets of rotating drums 33 respectively. The structure of the welding wire tray mechanism 3 facilitates the pre-winding of aluminum wire 7 and titanium wire 8.

[0034] The main body of the welding wire limiting mechanism 4 is a T-shaped limiting frame 41. The top of the limiting frame 41 is provided with a threaded groove, which is connected to the wire hole therein. A locking knob 42 is threaded in the threaded groove, and the aluminum wire 7 and titanium wire 8 on the rear side of the welding wire limiting mechanism 4 are wound into a winding wire 9. The structure of the welding wire limiting mechanism 4 facilitates the limiting of aluminum wire 7 and titanium wire 8 of different specifications, ensuring the preparation effect of subsequent winding.

[0035] The working principle and usage process of this utility model are as follows: When the device is required to work, the welding wire clamping mechanism 10 on the welding wire driving mechanism 5 clamps the front ends of the aluminum wire 7 and titanium wire 8. At the same time, the welding wire limiting mechanism 4 is adjusted. Then, the drive motor 52 drives the welding wire clamping mechanism 10 to rotate, and the aluminum wire 7 and titanium wire 8 on the front side of the welding wire limiting mechanism 4 are screwed into a winding wire 9. Then, the aluminum wire 7 and titanium wire 8 are mechanically wound together into a winding wire 9 for filling by using a double-wire winding method. This can effectively improve the fusion effect, increase the material strength, improve the integration performance of arc additive parts, and solve the problem that existing devices are difficult to efficiently wind and prepare aluminum wire 7 and titanium wire 8 according to requirements.
