Description

Technical Field

[0001] This application relates to the field of packaging technology for titanium alloy coiled wire, and in particular to a non-destructive packaging device for titanium alloy coiled wire. Background Technology

[0002] Titanium alloys are widely used in many fields due to their excellent properties, such as meeting the requirements of high strength, lightweight and corrosion resistance in the aerospace field; titanium alloy coiled wire has been widely used in medical devices, artificial joints and other fields due to its good biocompatibility and corrosion resistance; and it is also used in corrosion-resistant structural components such as submarines and deep-sea probes to meet the high requirements of marine environment for material corrosion resistance.

[0003] Titanium alloy coiled wire is an important form of titanium alloy material. It is formed by repeatedly drawing titanium alloy rods to create wire. Because the diameter of the wire is significantly smaller than that of the rod, while its length is greatly increased, the titanium alloy wire is usually coiled after forming to facilitate packaging and transportation. Coiled titanium alloy wire is small in volume and light in weight, saving space and cost during transportation.

[0004] Currently, titanium alloy wires are processed, shaped, and coiled before being wrapped with plastic strapping for transport. However, titanium alloy wires are typically produced continuously, and shipments are often in large quantities. During transport, the coiled wires are often stacked and piled up, making them highly susceptible to friction and wear on the strapping, which in turn damages the wire surface. Wear on the outer strapping can cause exposed wire. Since the wire was under coiling stress, this exposed wire can diffuse unstablely outwards due to this stress, posing a safety hazard and hindering the safe and undamaged transport of the wires. Summary of the Invention

[0005] To address the aforementioned problems, this application aims to provide a non-destructive packaging device for titanium alloy coiled wire, which can provide circumferential support for the coiled wire, improve its circumferential strength, and avoid the problem of the wire being squeezed into an elliptical shape under the influence of external forces. At the same time, it can mechanically limit the coiled wire, restricting the safety hazards caused by its unwinding and diffusion, and can achieve non-destructive transportation during transportation.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a non-destructive packaging device for titanium alloy coiled wire, characterized in that: the non-destructive packaging device includes a circumferential support member that supports the coiled wire along the circumferential direction, and a limiting member that restricts the radial diffusion of the coiled wire is also provided on the circumferential support member.

[0007] Preferably, the circumferential support member is a support ring that is attached to the inner side of the coiled filament, and the support ring includes an outer layer, an inner layer and a reinforcing layer sandwiched in the middle.

[0008] Preferably, the limiting member is a limiting groove plate that is radially connected to the inner side of the support ring and extends to the outer layer for a certain length, and the limiting groove plate and the outer layer form an open cavity for the coiled filament.

[0009] Preferably, each of the limiting groove plates has an axially opening at its outer end, and a limiting rod for radially limiting the coiled wire is inserted into the limiting hole.

[0010] The beneficial effects of this application are: the non-destructive packaging device can achieve circumferential support for the coiled wire through circumferential support components. Under the action of circumferential support, the circumferential strength of the coiled wire can be improved, avoiding the problem of the wire being squeezed and becoming elliptical under the influence of external forces. Furthermore, the mechanical limitation of the coiled wire by the limiting components restricts the safety hazards caused by its unwinding and diffusion, and can achieve non-destructive transportation during transportation.

[0023] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] See attached document Figures 1-11 The diagram illustrates a non-destructive packaging device for titanium alloy coiled wire. This device includes a circumferential support member that supports the coiled wire 1 along its circumferential direction. This circumferential support member enables circumferential support of the coiled wire 1. Figure 6 As shown, under the action of circumferential support, the circumferential strength of the coiled wire can be improved, avoiding the problem of the wire being squeezed into an elliptical shape under the influence of external force.

[0025] To address the current problem of radial unwinding of the filaments due to coiling stress after the strapping is worn down, such as... Figure 6-7 As shown, a limiting member is also provided on the circumferential support member to restrict the radial diffusion of the coiled filament 1. This limiting member mechanically limits the coiled filament, thereby restricting the safety hazards caused by its unwinding and diffusion.

[0026] Specifically, such as Figure 1 As shown, the circumferential support member is a support ring 2 attached to the inner side of the coiled filament 1. To avoid the problem of excessive weight of the metal support ring 2, which would make it difficult to coil the filament and result in high transportation costs, the support ring 2 includes an outer layer 21, an inner layer 22, and a reinforcing layer 23 sandwiched in between. The outer layer 21 and the inner layer 22 are preferably made of pine cone board bent into a circumferential ring shape, which reduces the weight of the support ring 2 compared to metal. To improve the supporting strength of the pine cone board 2, the reinforcing layer 23 is preferably a thin metal plate sandwiched between the outer layer 21 and the inner layer 22, ensuring the supporting strength of the support ring 2. During the filament forming process, the filament is directly coiled onto the support ring 2.

[0027] Specifically, such as Figure 2 As shown, the limiting member is a limiting groove plate 3 radially connected to the inner side of the support ring 2 and extending a certain length to the outer layer 21. An open cavity 3a is formed between the limiting groove plate 3 and the outer layer 21 to allow the filament to be coiled. The formed filament is directly coiled and wound into the open cavity 3a until the outer side of the filament is close to the outer end of the limiting groove plate 3, thus completing the coiling of the filament on a single support ring 2. The coiled filament is then axially (upper and lower sides) limited by the limiting groove plate 3 to prevent axial unwinding.

[0028] To achieve radial unwinding limitation of the aforementioned coiled wire, such as Figure 10 As shown, each of the limiting groove plates 3 has an axially formed limiting hole 3b near its outer end, and a limiting rod 4 for radially limiting the coiled wire 1 passes through the limiting hole 3b. After the wire is coiled onto the support ring 2 a certain number of times, as described above... Figure 6-7 As shown, the limiting rod 4 is inserted into the limiting hole 3b of the limiting groove plate 3, thereby achieving radial limitation on the outer side of the coiled wire, effectively preventing the wire from easily unwinding and spreading under the action of coiling stress. When multiple coiled wires are stacked and transported, the limiting groove plate 3 separates the upper and lower coiled wires, thus avoiding friction and wear between them during transportation. At the same time, the limiting groove plate 3 covers and limits the wires in the radial direction, also preventing contact wear between horizontally adjacent coiled wires, achieving damage-free transportation of the coiled wires.

[0029] like Figure 8 As shown, when multiple coils of wire are stacked and transported, the instability of transportation can cause the support rings 2 to shift or slip off, making it difficult to unload the wire later. Therefore, to solve this problem, it is preferable to stack the support rings 2 after coiling, and then insert the limiting rods 4 into the limiting holes 3b on multiple support rings 2 simultaneously. It is also preferable to fix the limiting rods 4 with nuts to connect multiple support rings 2, thereby avoiding the problem of them falling off during transportation.

[0030] In actual operation, the number of turns of wire of each specification (with inconsistent outer diameter) on the support ring 2 varies, resulting in inconsistent outer diameters of the wire after it is wound on the support ring 2. Therefore, as... Figure 10 As shown, the limiting hole 3b has a strip-shaped hole structure, which facilitates the limiting of wires with different outer diameters. Furthermore, it facilitates the quick insertion and positioning of the limiting rod 4. Preferably, as shown... Figure 11 As shown, an embedding groove 3c is provided on one side of the limiting hole 3b. The limiting rod 4 is quickly embedded into the corresponding embedding groove according to the outer diameter position of the wound wire, thereby realizing the radial rapid limiting of different wound wires, and at the same time avoiding the problem of the limiting rod 4 sliding in the limiting hole 3b due to the coiling stress of the wire.

[0031] The principle of this application is as follows: When using the non-destructive packaging device, the processed filament is coiled and wound around the support ring 2 a certain number of times, so that the outer filament is close to the outer end of the support ring 2. Then, multiple support rings 2 are stacked. After stacking, the limiting rod 4 passes through the limiting hole 3b of multiple support rings 2. On the basis of radial limiting of the coiled filament, the device also limits the connection of multiple support rings 2 in the stacked state, so that multiple support rings become an integral structure. This avoids the problem of radial unwinding of the filament and the offset and slippage of the support rings 2 during transportation, and realizes non-destructive packaging and transportation of filament.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this application. Various changes and modifications may be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
