Problems solved by technology

[0003] For the rolling process: the rolled thick-diameter titanium alloy wire has a large tolerance span and poor roundness. In order to meet the use requirements, skinning treatment is usually required, and the skinning amount usually reaches about 1mm, and the yield is reduced by 15%. ~20%, the processing scrap is expensive but difficult to recycle, which greatly increases the production cost
[0004] For the wire drawing process: titanium alloy has high strength, and the titanium alloy wire with a value higher than φ10 has a large resilience when drawing, and is prone to drawing cracks. When demolding and breaking the wire, the wire is easy to pop out and burn the worker, and damage the machine at the same time.

Embodiment 1

[0037] see figure 1 As shown, the present embodiment prepares the titanium alloy wire blank, and the specific process is as follows:

[0038] Take a group of TC4 titanium alloy discs and add them to the heating furnace, raise the temperature to 950°C in an argon atmosphere, and keep warm for 10 minutes. Using a four-roller continuous rolling mill, four passes are used for rolling, and the total deformation is 65%. The discs are rolled Made of φ14 titanium alloy wire;

[0039] Then take a group of TC4 titanium alloy discs and put them into the heating furnace, raise the temperature to 1000°C in an argon atmosphere, and keep it warm for 8 minutes. Using a four-roller continuous rolling mill, six-pass rolling, the total deformation is 82%, and the discs are Rolled into φ10 titanium alloy wire.

Embodiment 2

[0041] see figure 1 As shown, the present embodiment pretreats the titanium alloy wire blank prepared in Example 1, and the specific process is as follows:

[0042] annealing:

[0043] Take the φ14 titanium alloy wire and put it into the heating furnace, raise the temperature to 780°C and keep it for 50 minutes, then take it out of the furnace and air cool it to 120°C to complete the annealing treatment of the φ14 titanium alloy wire;

[0044] Take the φ10 titanium alloy wire and put it into the heating furnace, raise the temperature to 750°C and keep it for 70 minutes, then take it out of the furnace and air cool it to 120°C to complete the annealing treatment of the φ10 titanium alloy wire;

[0045] Pickling:

[0046] Add φ14 titanium alloy wire into dilute sulfuric acid solution with a volume fraction of 7%, scrub with a wire brush for 25 minutes, rinse with tap water and dry with hot air;

[0047]Add the φ10 titanium alloy wire into a dilute sulfuric acid solution with ...

Embodiment 3

[0051] see figure 1 As shown, in this embodiment, the wire blank of φ10 is drawn for four passes, and the specific process is as follows:

[0052] Heat treatment: import the pretreated silk billet into the heating furnace, heat and keep it warm under the protection of argon gas;

[0053] Multi-pass wire drawing: Pass one end of the heat-treated wire billet through the drawing die and pull it through the tractor, then repeat the heat treatment and drawing until the designed wire diameter is reached, the winding machine coils the wire, and each coil is demolded Front stop, the self-locking device clamps the wire and cuts off from the end of the wire;

[0054] The specific parameters are shown in Table 1:

[0055] Table 1

[0056]

[0057] Finished product annealing: Put the closed wire into a heating furnace, raise the temperature to 680°C, keep it warm for 2 hours, and then air cool to room temperature to make titanium alloy wire.

Abstract

The invention relates to a production process of thick-diameter titanium alloy wire, which belongs to the technical field of metal material forming and processing. The process includes wire blank preparation, wire blank pretreatment and wire drawing. Coating compound lubricating powder by powder spraying, the lubricating powder has good adhesion and is not easy to fall off. It is fully lubricated during the wire drawing process and straightened before the wire drawing to reduce the anisotropy of the wire drawing and reduce the occurrence of drawing cracks; in this process , the wire blank is drawn under a relatively high plasticity to reduce the resilience of the wire drawing. At the same time, a self-locking device for wire drawing production is provided, and the broken wire is monitored through a photoelectric sensor. When the broken wire occurs, the wire is clamped in time to prevent high temperature. The rebound of the wire will burn workers and damage equipment, reducing safety risks; in addition, the roundness of the wire produced by the present invention is 0.009-0.023mm, no need for peeling treatment, and the yield is high.

Description

technical field [0001] The invention belongs to the technical field of metal material forming and processing, and in particular relates to a production process of a thick-diameter titanium alloy wire. Background technique [0002] Due to its excellent mechanical properties and corrosion resistance, titanium alloys are gradually replacing stainless steel in the electronics, automotive, aerospace and medical industries. As a conventional metal product, the production process of round wires has naturally become one of the development priorities. For the production of thick wire diameter titanium alloy wire, the main processes are rolling and wire drawing. [0003] For the rolling process: the rolled thick-diameter titanium alloy wire has a large tolerance span and poor roundness. In order to meet the use requirements, skinning treatment is usually required, and the skinning amount usually reaches about 1mm, and the yield is reduced by 15%. ~20%, the processing scrap is expensi...
