Description

Technical Field

[0001] This utility model belongs to the field of wire polishing technology, and specifically relates to a device for peeling and polishing titanium alloy coiled wire. Background Technology

[0002] Titanium alloys are widely used in aerospace, medical devices, and high-end equipment manufacturing due to their superior properties such as high strength, corrosion resistance, and lightweight. Titanium alloy coiled wire, as an important basic material, directly affects the quality and reliability of subsequent products due to its surface finish, dimensional accuracy, and mechanical properties. In the production and processing of titanium alloy wire, peeling and polishing are key processes, aimed at removing defects such as oxide scale and scratches from the wire surface and improving the surface finish to a precise standard (e.g., Ra≤0.8μm).

[0003] In existing technologies, the stripping and polishing processes for titanium alloy coiled wire typically have the following drawbacks:

[0004] 1. Inefficiency caused by process separation: In traditional processing methods, peeling and polishing are mostly independent processes that need to be completed on different equipment. This not only increases the number of wire transfers, but also makes the wire prone to deformation due to multiple clamping. The production process is lengthy and inefficient.

[0005] 2. Insufficient tension control affects accuracy: Titanium alloy wire has high hardness and low elastic modulus, making it prone to vibration due to tension fluctuations during processing. This can lead to defects such as dimensional deviations during peeling and vibration marks on the polished surface. Existing equipment mostly uses a single roller pressing structure, which makes it difficult to accurately control the curvature and tension of the wire simultaneously, especially for small-diameter wires (such as those below Ф7mm).

[0006] 3. Poor polishing effect stability: Traditional polishing devices mostly use fixed grinding components, which cannot dynamically adjust the polishing intensity according to the wire diameter and surface condition. In addition, the wire surface is easily burned due to heat accumulation during the polishing process, making it difficult to achieve a gradual improvement in smoothness and resulting in poor consistency of finished product surface quality.

[0007] 4. Insufficient equipment adaptability: For titanium alloy billets of different wire diameters, existing peeling and polishing equipment usually requires the replacement of the entire mold or adjustment of parameters, resulting in a long debugging cycle and making it difficult to meet the flexible production needs of multi-specification wires.

[0008] In summary, the existing technology lacks a high-efficiency peeling and polishing device that can achieve continuous operation, precise control of tension and polishing force, and adapt to the processing of multi-specification wires. There is an urgent need to improve the processing quality and production efficiency of titanium alloy coiled wires through structural innovation. Summary of the Invention

[0009] To achieve the above objectives, this utility model provides the following technical solution: a titanium alloy coil wire peeling and polishing device, comprising an unwinding mechanism, a roller pressure adjustment mechanism, a wire processing mechanism, and a winding assembly arranged sequentially along the wire peeling and polishing processing direction;

[0010] The roller pressure adjustment mechanism controls the curvature and tension of the wire conveyed by the unwinding mechanism; the wire processing mechanism controls the size and smooths the surface of the wire after curvature and tension adjustment; and the winding assembly neatly winds up the processed wire.

[0011] The wire processing mechanism includes a stripping component, a polishing component, and a vertical roller pressing component. The stripping component performs coarse and fine stripping on the wire after curvature control and tension adjustment to ensure a smooth surface. The polishing component performs fine polishing on the wire after coarse and fine stripping to improve surface smoothness. The vertical roller pressing component performs final curvature adjustment and tension calibration on the polished wire.

[0012] As a further improvement of this utility model, the peeling assembly includes a coarse peeling die and a fine peeling die. The coarse peeling die controls the cutting depth, and the fine peeling die controls the dimensional accuracy and surface finish. The peeling amount and speed are optimized for blanks of different wire diameters.

[0013] As a further improvement of this utility model, the polishing assembly is composed of multiple flap wheels arranged in a front and rear configuration. Each flap wheel can rotate at an adjustable speed and revolve around the center of the wire blank, and the polishing force is adjusted by the degree of contact and pressing.

[0014] As a further improvement of this utility model, the roller pressure adjustment mechanism includes a vertical roller pressure tension assembly and a horizontal roller pressure tension assembly;

[0015] The vertical roller tensioning assembly precisely controls the wire curvature by adjusting the position of the vertical roller; the horizontal roller tensioning assembly optimizes the wire tension by adjusting the position of the horizontal roller.

[0016] As a further improvement of this utility model, both the unwinding mechanism and the winding assembly are driven by servo motors to ensure stable tension of the wire during unwinding and winding.

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

[0018] 1. At the unwinding end, a multi-roller pre-tension adjustment mechanism (two sets, one horizontal and one vertical) allows the titanium alloy coiled wire to enter the stripping assembly under adjustable tensile stress. This tension effectively prevents vibration during stripping and ensures stable dimensional accuracy. After stripping, the wire, under a certain tension, directly enters multiple sets of flap wheels for progressive polishing from coarse to fine. This process gradually improves surface finish, ultimately ensuring a high degree of consistency and stability in diameter and surface finish, achieving steady-state polishing.

[0019] 2. By integrating the take-up, unwinding, and tension control systems, the stripping and polishing processes are effectively combined, achieving seamless continuous operation. This innovation breaks away from the inefficient traditional method of separate stripping and polishing in coiled wire processing, significantly improving production efficiency.

[0021] Figure 2 This is a schematic diagram of the flap wheel structure of a titanium alloy coil wire peeling and polishing device.

[0022] The components include: 1. Unwinding mechanism; 2. Vertical roll pressure tension assembly; 3. Flat roll pressure tension assembly; 4. Peeling assembly; 5. Polishing assembly; 6. Vertical roll pressure assembly; and 7. Rewinding assembly. Detailed Implementation

[0023] See Figures 1 to 2 As shown, a titanium alloy coil wire stripping and polishing device is characterized by comprising an unwinding mechanism 1, a roller pressure adjustment mechanism, a wire processing mechanism, and a winding assembly 7 arranged sequentially along the stripping and polishing direction of the coil.

[0024] The roller pressing adjustment mechanism controls the curvature and adjusts the tension of the wire conveyed by the unwinding mechanism 1; the wire processing mechanism controls the size and processes the surface finish of the wire after curvature control and tension adjustment; the winding assembly 7 neatly winds up the processed wire.

[0025] The wire processing mechanism includes a stripping component 4, a polishing component 5, and a vertical roller pressing component 6. The stripping component 4 performs coarse and fine stripping on the wire after curvature control and tension adjustment to ensure a smooth surface. The polishing component 5 performs fine polishing on the wire after coarse and fine stripping to improve surface smoothness. The vertical roller pressing component 6 performs final curvature adjustment and tension calibration on the polished wire.

[0026] It should be noted that the titanium alloy coiled wire to be processed is first fed into the roll pressing adjustment mechanism through the unwinding mechanism 1 to precisely control the curvature and tension, and then enters the peeling assembly for rough and fine peeling to ensure dimensional accuracy and surface finish. Finally, it passes through the polishing assembly 5 and the vertical roll pressing assembly 6 to achieve efficient polishing and final curvature and tension calibration of the wire, and is neatly wound up by the winding assembly 7.

[0027] The vertical roller pressing assembly 6 ensures that the curvature of the wire meets the standard after polishing by precisely adjusting the position of the vertical roller. At the same time, the vertical roller pressing assembly further optimizes the tension, so that the wire remains stable during the winding process, and finally forms a titanium alloy coiled wire with a bright surface and uniform tension.

[0028] In a preferred embodiment, the peeling component 4 includes a coarse peeling die and a fine peeling die. The coarse peeling die controls the cutting depth, and the fine peeling die controls the dimensional accuracy and surface finish. The peeling amount and speed are optimized for blanks of different wire diameters.

[0029] It should be noted that the rough stripping die controls the amount of material cut to ensure that the surface of the billet is initially flat; the fine stripping die precisely controls the dimensional accuracy and surface finish. For titanium alloy wires with a diameter of less than 7mm, the required fine surface finish is achieved by optimizing the amount and speed of stripping.

[0030] For titanium alloy blanks of different wire diameters, the process parameters of the rough stripping and fine stripping dies need to be precisely adjusted to ensure the best match between stripping amount and speed, thereby achieving high-precision dimensions and excellent surface finish for wires with diameters below Ф7mm.

[0031] In a preferred embodiment, the polishing assembly 5 is composed of multiple flaps arranged in a series. Each flap can rotate at an adjustable speed and revolve around the center of the wire blank. The polishing force is adjusted by the degree of contact and pressure. The grit size of the flaps is selected sequentially from coarse to fine to ensure that the polishing smoothness is improved step by step. By adjusting the direction and position of the flap movement, the degree of contact and pressure with the wire can be precisely controlled to achieve different polishing force requirements.

[0032] In a preferred embodiment, the roller pressure adjustment mechanism includes a vertical roller pressure tension assembly 2 and a horizontal roller pressure tension assembly 3;

[0033] The vertical roller tensioning assembly 2 precisely controls the curvature of the wire by moving and adjusting the position of the vertical roller; the flat roller tensioning assembly 3 optimizes the tension of the wire by moving and adjusting the position of the flat roller.

[0034] It should be noted that by designing a reasonable layout of the roller tensioning mechanism, the wire end is led out and passes through the vertical roller tensioning assembly 2 and the horizontal roller tensioning assembly 3, so as to achieve the synergistic effect of the two sets of roller tensioning mechanisms, ensuring that the curvature and tension of the wire in the pressure roller reach the optimal state, thus laying a solid foundation for the subsequent peeling and polishing processes.

[0035] Meanwhile, as the titanium alloy coiled wire passes through two sets of horizontal and vertical multi-roller pre-tension adjustment mechanisms and enters the peeling die cavity, the tension is stable, vibration is avoided, and dimensional accuracy is ensured.

[0036] In a preferred embodiment, both the unwinding mechanism 1 and the winding assembly 7 are driven by servo motors to ensure stable tension of the wire during unwinding and winding, avoiding wire deformation or damage caused by tension fluctuations, and further improving overall processing efficiency and finished product quality. Through precise control by the servo motors, the unwinding and winding processes are synchronized and coordinated, ensuring that the wire maintains optimal tension in each process, ultimately achieving the preparation of high-precision, high-smoothness titanium alloy coiled wire.

[0037] In practical applications, the titanium alloy coiled wire to be processed is first initially unwound by the unwinding mechanism 1, and then enters two sets of horizontal and vertical multi-roller pre-tension adjustment mechanisms to ensure stable wire tension and avoid vibration. Next, the wire passes through a coarse peeling die and a fine peeling die in sequence. The coarse peeling die controls the cutting depth, while the fine peeling die precisely controls dimensional accuracy and surface finish. For wires with a diameter of Ф7mm or less, the peeling amount and speed are optimized. Finally, the polishing assembly 5 performs progressive polishing, with the flap wheel grit size increasing from coarse to fine to ensure a gradual improvement in surface finish, ultimately achieving the preparation of high-precision, high-smoothness titanium alloy coiled wire. Through this device, the titanium alloy wire is not only processed without surface defects such as vibration marks, but also significantly improved in processing efficiency and finished product quality, ensuring high precision and excellent surface finish for wires with a diameter of Ф7mm or less, meeting the stringent requirements of high-end manufacturing fields.

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.
