Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to an automatic titanium wire coating system. Background Technology

[0002] Titanium alloys are important lightweight structural materials, widely used in aircraft component manufacturing due to their high specific strength, corrosion resistance, and excellent high-temperature performance. Titanium alloy fasteners, serving as bridges connecting riveted base structures, are in high demand and play an irreplaceable role in ensuring structural stability. In recent years, the rapid development of China's aerospace industry has placed higher demands on the quality and production efficiency of titanium alloy fasteners. Currently, to ensure consistency in fastener dimensions and quality, aerospace fastener manufacturers commonly use large-weight coiled wire and a continuous upsetting process using molds to manufacture titanium alloy fasteners. However, the upsetting process makes the material prone to cracking, which can even lead to mold failure in severe cases. To ensure lubrication during the upsetting process, improve the metal flow state on the material surface, and reduce upsetting cracking, a self-lubricating coating must be applied to the surface of the titanium alloy wire. This solves the upsetting cracking problem during coiled wire processing and improves the yield of fasteners.

[0003] Titanium wire surface coating processes include dip coating, wiping coating, and spray coating, which typically require pretreatment such as ultrasonic cleaning and post-treatment such as drying and close-packing. These processes involve numerous steps, and currently, most manufacturers use manual coating, consuming significant human resources. Uneven force on the wire during manual coating can easily lead to uneven coating thickness, nodules, and bubbles. Coating quality is highly dependent on the operator's experience, and multiple coating operations are required if the single coating is unsatisfactory, further increasing production difficulty. Publication number CN 219923512 U discloses a coating system for lubricating coatings on the surface of titanium alloy wires, which uses an automatic coating device to replace manual coating, effectively solving the drawbacks of manual coating. However, during the coating process, the titanium wire is prone to shaking during its movement, making it difficult to maintain a stable wire path and causing jamming during take-up. Furthermore, existing titanium wire coating equipment has a complex take-up process, where the titanium wire becomes tangled and uneven during winding, making it impossible to maintain the flatness of the collected titanium wire.

[0004] Therefore, the above-mentioned issues should be considered and resolved during the coating process of titanium wire. Utility Model Content

[0045] This embodiment provides an automatic titanium wire coating system. A steel wire roll is sleeved on the sleeve rod 103 of the turntable 102 for wire feeding. The steel wire first passes through the clamping mechanism 200, and is then conveyed to the pre-bending mechanism 300 by the transmission roller of the clamping mechanism 200. The front end of the titanium wire is pre-bent, and the titanium wire is supported by the support roller 311. This pre-bending process gives the titanium wire a certain bending range, making it easier to coat the surface of the steel wire. In addition, when winding the titanium wire, the range of secondary bending of the titanium wire can be reduced, thereby reducing the probability of cracks appearing on the surface coating of the titanium wire and improving the integrity of the coated titanium wire. After passing through the coating cylinder 302, the titanium wire is then pulled to the take-up mechanism 400 by the coating guide roller 312, so that the titanium wire can be wound on the take-up reel 405.

[0046] This embodiment provides an automatic titanium wire coating system that, after coating, performs wire take-up and take-up. The working principle of the take-up and take-up components is as follows: First, the variable frequency motor 408 starts, the transmission wheel rotates and drives the driven wheel 411 to rotate via the belt, thereby driving the take-up reel to rotate via the transmission shaft (at this time, the limiting rib is in an open state to achieve the limiting function). While the wire is winding, the drive motor 406 starts, the moving screw 407 drives the connecting plate 404 to move back and forth slowly, thereby causing the take-up reel 405 on the connecting plate 404 to move back and forth slowly, so that the wire can be arranged and stacked flatly on the take-up reel 405, thus completing the wire take-up work. After the wire is wound up, the wire coil needs to be removed. At this time, the drive cylinder 415 is started. The drive cylinder 415 drives the telescopic shaft 416 and the inner pull sleeve 417 to retract, and the limiting rib plate 414 is retracted. The limiting rib plate 414 is brought together and retracted, so that the outer side of the take-up reel 405 loses its limit, and the wound wire coil can be removed to complete the wire removal work.

[0047] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
