Description

Technical Field

[0001] This utility model belongs to the field of wire hot drawing technology, and specifically relates to a titanium alloy coil wire drawing device. Background Technology

[0002] Metal wire drawing is a diameter reduction process for producing small-gauge fine wires. Titanium alloy wires, due to their limited hcp slip system and limited plastic deformation capacity (typically no more than 20% deformation per pass), have a complex process path and low efficiency when drawing fine-gauge titanium alloy wires. To improve drawing efficiency, hot drawing is a common method. Hot drawing allows for dynamic recovery and recrystallization during the process by adjusting the heating temperature and holding parameters, avoiding the problem of cumulative work hardening that prevents further wire diameter reduction.

[0003] Traditional titanium alloy hot drawing mechanisms employ single-unit single-tube or double-unit double-tube systems, with uniform temperature control for heating. Even with double-unit double-tube systems, a unified process is required, making independent process control impossible and limiting processing flexibility. Furthermore, a simple large circular reel is used for wire feeding, and the drawing and take-up machine horizontally reels the wire. After drawing, the wire must be manually unloaded and transferred back to the feeding reel, then fed again and drawn again, in a continuous cycle. This operation results in limited and inflexible matching of specifications and processes, inconvenient wire feeding and take-up, low production efficiency, and high operational difficulty. The wire may also eject during the unloading process from the take-up reel, posing numerous safety hazards.

[0004] Therefore, it is necessary to provide a titanium alloy coil wire drawing device to solve the problems mentioned in the background art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a titanium alloy coiled wire drawing device, comprising a wire feeding rack, a graphite emulsion hanger, a heating furnace, a drawing mechanism, and a take-up rack arranged sequentially along the wire drawing direction, characterized in that: the heating furnace includes a preheating chamber and a heating and heat preservation chamber;

[0006] At least four sets of the wire feeding rack and the wire take-up rack are provided, with each set of the wire feeding rack and the wire take-up rack corresponding to one other set.

[0007] The drawing mechanism is used to hot draw the titanium alloy wire that has been heat-treated in the heating furnace.

[0008] As a further improvement of this utility model, the wire feeding rack includes a first support, a first I-beam wheel, and a damper. The first I-beam wheel is rotatably mounted on the first support and is used to wind closely packed titanium alloy coil blanks.

[0009] The damper is mounted on the connecting shaft between the first I-beam and the first bracket.

[0010] As a further improvement of this utility model, the graphite emulsion hanger includes a collection trough, one end of which is provided on the collection trough and the other end of which is connected to a crossbeam.

[0011] As a further improvement of this utility model, a pressure pump is provided inside the conveying pipeline.

[0012] As a further improvement of this utility model, the preheating chamber and the heating and insulation chamber are combined into a set of independent temperature-controlled heating tubes, and the number of independent temperature-controlled heating tubes is set according to the number of the wire feeding rack and the wire taking rack.

[0013] As a further improvement of this utility model, the take-up wire rack includes a second bracket, a second I-beam wheel is rotatably mounted on the second bracket, and a motor is also fixedly mounted on the second bracket;

[0014] The output shaft of the motor is coaxially connected to the second I-beam.

[0015] As a further improvement of this utility model, the motor is preferably a stepper motor.

[0016] As a further improvement of this utility model, cable positioning holes are provided on both the first bracket and the second bracket.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Breaking away from the traditional single-unit or double-unit double-unit heating and drawing control mechanism and unified process control system for wire or coiled wire, this invention can reasonably set up multiple sets of independently operating combined drawing mechanisms according to actual working needs. Multiple independent temperature-controlled heating tubes are set in one heating furnace, which greatly improves production efficiency, process control flexibility, saves the cost of heating furnace equipment, and reduces the volume space of drawing equipment.

[0019] 2. The first I-beam reel is used for wire feeding and the second I-beam reel for wire take-up, so that each titanium alloy wire can be fed, threaded, pulled and taken up independently. The pulling speed and heating temperature can be controlled independently. The wire does not need to be unloaded during the entire pulling process. The operation can be switched at any time to achieve efficient, flexible, safe and reliable operation. Attached Figure Description

[0021] Figure 2 This is a side view of a heating furnace for a titanium alloy coil wire drawing device;

[0022] Figure 3This is a schematic diagram of a graphite emulsion hanger for a titanium alloy coiled wire pulling device.

[0023] The components include: 1. wire feeding rack; 2. graphite emulsion hanging rack; 3. preheating chamber; 4. heating and insulation chamber; 5. drawing mechanism; 6. wire taking-up rack; 7. cross frame; 8. collection trough; and 9. conveying pipeline. Detailed Implementation

[0024] See Figures 1 to 3 As shown, a titanium alloy coiled wire drawing device includes a wire feeding rack 1, a graphite emulsion hanger 2, a heating furnace, a drawing mechanism 5, and a take-up rack 6 arranged sequentially along the wire drawing direction.

[0025] Specifically as follows:

[0026] The heating furnace includes a preheating chamber 3 and a heating and insulation chamber 4;

[0027] Multiple sets of the wire feeding rack 1 and the wire take-up rack 6 are provided, with each set of the wire feeding rack 1 and the wire take-up rack 6 corresponding one-to-one.

[0028] The drawing mechanism 5 is used to hot draw the titanium alloy wire after it has been heat-treated in the heating furnace.

[0029] In detail, in this embodiment, the titanium alloy coiled wire drawing device of the present invention is used. During use, the titanium alloy coiled blank is pre-wound onto the wire feeding rack 1. After winding, the wire feeding rack 1 is placed on the wire feeding station. The wire end of the titanium alloy wire is led out and passes through the graphite emulsion hanger 2. After passing through the corresponding preheating chamber 3 and heating and heat preservation chamber 4, it is heat-treated and then passes through the drawing mechanism 5. After the wire is hot-drawn, it is introduced into the take-up rack 6 for winding and storage. Different take-up racks 6 and wire feeding racks 1 have the same diameter specifications and are respectively arranged on both sides of the take-up end box and the wire feeding section.

[0030] The hot drawing rate of titanium alloy wire can be controlled by adjusting the take-up rack 6. That is, the hot drawing rate of titanium alloy wire of different specifications and sizes can be reasonably controlled and adjusted to ensure the heat treatment effect of titanium alloy wire in the heating furnace, thereby improving the drawing effect of the drawing mechanism 5.

[0031] like Figure 1 As shown, the present invention also includes: the wire feeding rack 1 includes a first support, a first I-beam wheel, and a damper; the first I-beam wheel is rotatably mounted on the first support and is used to wind closely packed titanium alloy coil blanks; the damper is mounted on the connecting shaft between the first I-beam wheel and the first support.

[0032] It should be noted that the titanium alloy coiled wire is wound into a dense arrangement using the first I-beam, and after the dense arrangement is completed, its first support is placed on the wire laying station.

[0033] The damper restricts and reduces the rotation speed of the first I-beam under the tension of the take-up frame 6, thereby maintaining a certain tension in the titanium alloy wire throughout the process, preventing the wire from slack, and further improving the hot drawing effect of the titanium alloy wire.

[0034] like Figure 3 As shown, the present invention also includes: the graphite emulsion hanger 2 includes a collection tank 8, one end of a conveying pipe 9 is provided on the collection tank 8, and the other end of the conveying pipe 9 is connected to a crossbeam 7; a pressure pump is provided in the conveying pipe 9.

[0035] When in operation, the pressurized pump transports the graphite emulsion in the collection tank 8 to the cross frame 7 through the conveying pipe 9. The cross frame 7 then performs the emulsion coating operation on the titanium alloy wire inside, thereby ensuring the heat treatment effect of the titanium alloy wire in the heating furnace.

[0036] Excess graphite emulsion drips from both ends of the crossbeam 7 into the collection tank 8, thus completing the recycling of the graphite emulsion.

[0037] like Figure 1 - Figure 2 As shown, this utility model also includes: the preheating chamber 3 and the heating and insulation chamber 4 are combined into a set of independent temperature-controlled heating tubes, and the number of independent temperature-controlled heating tubes is set according to the number of the wire feeding rack 1 and the wire taking rack 6.

[0038] In practical work, this scheme is based on the principle that the wire feeding rack 1 and the wire taking rack 6 can be set up in multiple groups according to actual operation needs. At the same time, the preheating chamber 3 and the heating and heat preservation chamber 4 are set up in equal numbers. This allows the drawing speed, preheating and heating temperature, and deformation amount of each drawing pass to be operated independently during the drawing process of multiple groups of titanium alloy wires, without interference, and all sharing a heating furnace.

[0039] The take-up rack 6 includes a second bracket, a second I-beam wheel rotatably mounted on the second bracket, and a motor fixedly mounted on the second bracket;

[0040] The output shaft of the motor is coaxially connected to the second I-beam wheel; the motor is preferably a stepper motor.

[0041] By changing the stepper motor speed, the drawing speed of the heat treatment, as well as the preheating and heating time, can be quickly adjusted to ensure the heat drawing effect of titanium alloy wire.

[0042] like Figure 1 As shown, cable positioning holes are provided on both the first bracket and the second bracket.

[0043] Since the take-up rack 6 and the unwind rack 1 have a certain width (exceeding the inner diameter of the independent temperature-controlled heating tube), the unwinding wire is positioned at the same center line position by the wire positioning hole before entering the heating tube and after being pulled out.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
