Description

Technical Field

[0001] This application relates to the field of cable production technology, and more specifically, to a wire shaping mold and rigid cable production equipment. Background Technology

[0002] In the production process of rigid cables, the wire needs to be shaped by a mold before subsequent processes can be carried out.

[0003] In related technologies, during the process of wire passing through the shaping mold, the friction between the wire and the shaping mold can cause the shaping mold to move, thus affecting the shaping effect. In fact, when the friction between the wire and the shaping mold is large, it can even cause the shaping mold to move and lead to its damage. Utility Model Content

[0004] In order to at least solve some of the problems mentioned in the related technologies, this application provides a wire shaping mold and a rigid cable production equipment.

[0005] To achieve the above objectives, this application provides a wire shaping mold for use in rigid cable production equipment. The wire shaping mold includes a tube body with a wire groove formed thereon, through which the wire passes. A guide wire portion is provided on the tube body to guide the wire; the guide wire portion is located at one end of the wire groove and communicates with the wire groove. A limiting portion is provided between the guide wire portion and the tube body to restrict the relative position of the tube body on the rigid cable production equipment.

[0006] Furthermore, the conductor portion is configured as a flared ring, and the diameter of the end of the flared ring closer to the tube body is L1, and the diameter of the end of the flared ring farther from the tube body is L2, satisfying: L1≤L2.

[0007] Furthermore, a protective layer is provided on the flared ring, with one end of the protective layer away from the tube body abutting against the side wall of the flared ring, and the other end of the protective layer near the tube body abutting against the limiting part.

[0008] Furthermore, the limiting part includes a fixing member, which is sleeved on the tube body and fixed relative to the tube body. The end of the protective layer near the tube body abuts against the fixing member.

[0009] Furthermore, the fastener is configured as a fastening bolt, which is threadedly installed on the pipe body.

[0010] Furthermore, the fastener is configured as an annular step, which is located on the tube body near the flared ring.

[0011] This application also provides a rigid cable production apparatus, including a winding rotary machine and a wire shaping mold as described in any of the above embodiments. The winding rotary machine winds resin-coated glass fibers to form the wire, the wire is threaded into the wire groove, and the wire groove shapes the wire.

[0012] Furthermore, at least two wire shaping molds are provided at the outlet of the winding and rotating machine, and the wire shaping molds are arranged sequentially as a first shaping mold and a second shaping mold along the moving direction of the cable, and the wire passes through the first shaping mold and the second shaping mold in sequence.

[0013] Furthermore, the diameter of the tube body of the first shaping mold is L3, and the diameter of the tube body of the second shaping mold is L4, satisfying that: L3 > L4.

[0014] Furthermore, the length of the first shaping mold is L5, and the length of the second shaping mold is L6, satisfying that L5 < L6.

[0015] The above technical solution involves shaping the wire by inserting it into a groove from the conductor section of the tube and moving it along the groove until it exits from the end furthest from the conductor section. The groove constrains and shapes the wire. The limiting part on the tube can be installed or engaged with the rigid cable production equipment. The friction generated by the wire passing through the groove is transmitted from the tube to the limiting part, and then from the limiting part to the rigid cable production equipment, preventing deformation of the conductor section of the tube due to stress, which would affect the normal insertion of the wire.

[0016] The wire shaping mold of this application, by providing a conductor section on the tube body, makes it easier for the wire to pass into the wire groove, reducing the difficulty of the wire shaping operation. The limiting section on the tube body not only makes the tube body easier to fix, making the structure of this embodiment more reasonable, but also prevents the conductor section from being subjected to external forces, protecting the conductor section and ensuring stable wire shaping operation.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] This application provides a wire shaping mold to solve the problem in related technologies that shaping molds are prone to movement or even damage during shaping operations.

[0030] Please see Figures 1 to 3 A wire shaping mold is used in rigid cable production equipment. The wire shaping mold includes a tube body 100 with a wire groove 110 through which the wire passes. A conductor portion 200 is provided on the tube body 100 to guide the wire. The conductor portion 200 is located at one end of the wire groove 110 and communicates with it. A limiting portion 300 is provided between the conductor portion 200 and the tube body 100 to limit the relative position of the tube body 100 in the rigid cable production equipment.

[0031] Specifically, in the production process of wire, glass fibers are usually impregnated with resin, and then wound around the resin-impregnated glass fibers to coat them and form wire.

[0032] The wire needs to pass through a wire shaping mold to be shaped for subsequent processing. In actual production, the wire feeding equipment passes the wire through the wire groove 110 on the tube 100, and the traction equipment pulls the wire from the outside of the wire groove 110. In this way, the wire is constrained by the tube 100 as it passes through the wire groove 110, thus completing the shaping process.

[0033] However, because the wire is coated with resin before winding and inevitably retains resin after winding, the friction between the wire and the wire shaping mold is relatively high. Furthermore, the need to control the diameter of the tube 100 for wire shaping further increases this friction. In addition, the shaping components in related technologies typically rely on protrusions to engage within a through hole. As a result, to ensure the shaping effect, the shaping component must remain stationary while the wire passes through it, thus bearing significant frictional forces. This easily causes deformation of the shaping component, affecting the shaping effect.

[0034] In this embodiment, the wire to be shaped passes through the conductor portion 200 of the tube 100 into the wire groove 110 and extends out from the end of the wire groove 110 away from the conductor portion 200. The limiting portion 300 is used to install or clamp the tube 100 to a suitable position on the rigid cable production equipment. In this way, the frictional force generated by the wire passing through the tube 100 is transmitted from the tube 100 to the limiting portion 300, and then from the limiting portion 300 to the frame of the rigid cable production equipment or other positions. This avoids the conductor portion 200 and the tube 100 itself being subjected to excessive force during the shaping process, prevents the conductor portion 200 from deforming due to friction, thus affecting the wire insertion, and ensures the overall structural stability of this embodiment, enabling it to work normally for a long time.

[0035] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, the conductor section 200 is configured with a flared ring 210, with the diameter of the end of the flared ring 210 near the tube body 100 being L1 and the diameter of the end of the flared ring 210 away from the tube body 100 being L2, satisfying: L1≤L2. The conductor is configured with a flared ring 210, and the end with the larger diameter faces away from the tube body 100, that is, towards the direction of the previous process step of the wire. In this way, after the wire is wound, it can directly extend into the wire groove 110 along the conductor section 200. The flared ring 210 of the conductor section 200 serves as a guide; any position of the wire extending into the flared ring 210 will be guided by the flared ring 210 to move into the wire groove 110, ensuring the practicality of this embodiment.

[0036] It should be noted that during the production of rigid cables, the cables are typically moved at the same horizontal level, undergoing processes such as resin impregnation, winding, and shaping in sequence. A certain degree of precision is required between each process to ensure smooth production. In this embodiment, the conductor portion 200 is configured as a flared ring 210, which reduces the precision requirements between the winding and shaping processes, making the production conditions of this embodiment easier to achieve and improving its practicality.

[0037] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, a protective layer 220 is provided on the flared ring 210. The end of the protective layer 220 away from the pipe body 100 abuts against the side wall of the flared ring 210, and the end of the protective layer 220 near the pipe body 100 abuts against the limiting part 300. The protective layer 220 is provided on the flared ring 210 to protect the flared ring 210 from being bumped or affected by other external components, so as to prevent deformation, damage or other situations that would affect the normal operation of the flared ring 210.

[0038] Furthermore, the protective layer 220 covers the flared ring 210, and one end of the protective layer 220 abuts against the limiting part 300. Thus, when the tube body 100 experiences friction from the wire, the force is transmitted to the limiting part 300. While the limiting part 300 transmits the force to the rigid cable production equipment, it inevitably affects the flared ring 210 as well. At this time, the force that should have been transmitted to the flared ring 210 is instead transmitted to the protective layer 220. After being dispersed by the protective layer 220, it is then evenly transmitted to the sidewall of the flared ring 210, thereby protecting the flared ring 210 from excessive force and ensuring its service life, as well as the overall service life of this embodiment.

[0039] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, the protective layer 220 is configured as a multi-layered metal wire with interlaced winding. This further reduces the difficulty of obtaining the material for the protective layer 220 and also reduces the difficulty of manufacturing the protective layer 220, thus making this embodiment easier to manufacture and process. The multi-layered metal wire wound around the flared ring 210 protects the flared ring 210 and can also disperse the force transmitted by the limiting part 300, making it highly practical.

[0040] In this embodiment, the specific material of the protective layer 220 is not limited and can be set arbitrarily according to actual use needs, such as iron wire, steel wire, copper wire, etc.

[0041] It should be noted that the protective layer 220 can also be designed as an integrally formed workpiece according to the shape of the flared ring 210, so as to achieve the effect of protecting the flared ring 210. The material of the protective layer 220 can also be any material that will not easily deform, such as hard rubber or metals such as copper wire or iron, to ensure that the protective layer 220 has sufficient strength to protect the flared ring 210.

[0042] In one embodiment, exemplarily, such as Figures 1 to 3 As shown, the limiting part 300 includes a fixing member, which is sleeved on the tube body 100 and fixed relative to the tube body 100. The end of the protective layer 220 near the tube body 100 abuts against the fixing member. The fixing member being sleeved on the tube body 100 ensures the flexibility of this embodiment. Specifically, when using this embodiment, the position of the fixing member, that is, the position on the tube body 100 where it connects to the rigid cable production equipment, can be determined according to the actual situation.

[0043] For example, the fastener can be positioned in the middle of the tube body 100, away from the flared ring 210. This way, the force generated during the wire shaping process will not affect the flared ring 210, thus protecting it. Alternatively, the fastener can be positioned close to the flared ring 210, with one end of the protective layer 220 abutting against the fastener. In this way, although the force on the fastener may affect the flared ring 210, it will be protected and dispersed by the protective layer 220, preventing any impact on the flared ring 210. Furthermore, the cooperation between the fastener and the protective layer 220 can improve the overall structural strength of this embodiment.

[0044] In one embodiment, exemplarily, such as Figure 3 As shown, the fixing component is a fastening bolt 310, which is threadedly installed on the tube body 100. Threads can be provided at any position on the tube body 100 as needed, allowing the fastening bolt 310 to be installed in a designated location for mounting or clamping. In this embodiment, the conductor portion 200 is a flared ring 210, and the fixing component is the fastening bolt 310. Both are relatively inexpensive and readily available materials, resulting in a low-cost and durable wire shaping mold. Furthermore, if any component in this embodiment is damaged, it is very easy to find identical or similar replacement parts nearby, further improving the durability of this embodiment.

[0045] In one embodiment, exemplarily, such as Figure 4 As shown, the fastener is configured as an annular step 320, which is located on the tube body 100 near the flared ring 210. The fastener is integrally formed on the tube body 100. Compared with a fastener installed on the tube body 100, the integral forming configuration can further improve the overall strength of the tube body 100 and the fastener, making the structure of this embodiment stronger and more durable.

[0046] Please see Figure 5 This application also provides a rigid cable production equipment, including a winding rotary machine 400 and a wire shaping mold as described in any of the above embodiments. The winding rotary machine 400 winds resin-coated glass fibers to form wires, which are threaded through a wire groove 110 and shaped by the wire groove 110.

[0047] In detail, the wire shaping mold is used in conjunction with the winding rotary machine 400 to complete some of the processes in the production of rigid cables. Simultaneously, other equipment is required, such as a wire feeding device, to continuously feed the glass fiber to the resin impregnation area. After impregnation, the winding rotary machine 400 winds and wraps the resin-laden glass fiber. After winding, it is sent to the wire shaping mold for shaping. During the shaping process, a traction device then passes the shaped wire through the wire shaping mold.

[0048] In one embodiment, exemplarily, such as Figure 5 As shown, at least two wire shaping molds are provided at the outlet of the winding and rotating machine 400. The wire shaping molds are sequentially arranged as a first shaping mold 510 and a second shaping mold 520 along the direction of wire movement, and the wire passes through the first shaping mold 510 and the second shaping mold 520 sequentially. When shaping the wire, multiple wire shaping molds are used to achieve different shaping effects. In this embodiment, the first shaping mold 510 and the second shaping mold 520 are provided so that the wire undergoes two shaping processes, enhancing the shaping effect. Of course, depending on the actual production needs, a third shaping mold, a fourth shaping mold, etc., can be further provided downstream of the second shaping mold 520; this embodiment does not impose any limitations on this.

[0049] Please continue reading. Figure 5 In one embodiment, for example, the diameter of the tube 100 of the first shaping mold 510 is L3, and the diameter of the tube 100 of the second shaping mold 520 is L4, satisfying L3 > L4. Setting the diameter of the first shaping mold 510 to be larger than the diameter of the second shaping mold 520 allows for initial shaping of the wire when it passes through the first shaping mold 510, thus initially limiting the wire's diameter. The wire then passes through the second shaping mold 520 for further limiting, ensuring the wire's diameter reaches the preset diameter and the shaping is complete. This multi-stage reduction of the wire's diameter avoids excessive single-stage reduction, which could lead to excessive friction when the wire passes through the tube 100, affecting the tube 100 or the limiting part 300 and causing damage to the tube 100. It also reduces the structural strength requirements of the tube 100, making this embodiment easier to use and manufacture. Simultaneously, it avoids excessive single-stage reduction that could damage the wire, ensuring the shaping effect of this embodiment and improving its practicality.

[0050] It is worth mentioning that, depending on the actual production situation, a third shaping mold, a fourth shaping mold, etc., can also be set up, and the diameters of the third shaping mold and the fourth shaping mold can be successively reduced, so that this embodiment can produce wires of any diameter. Similarly, while keeping the total reduction in wire diameter constant, more shaping molds can be set up to reduce the reduction in wire diameter per operation, thereby further reducing the production difficulty of this embodiment.

[0051] In one embodiment, exemplarily, such as Figure 5As shown, the length of the first shaping mold 510 is L5, and the length of the second shaping mold 520 is L6, satisfying L5 < L6. In this embodiment, the first shaping mold 510 is shorter in length to perform preliminary shaping of the wire and reduce its diameter, so that the wire can better enter the second shaping mold 520. The second shaping mold 520 is longer in length to further restrict the diameter of the wire while ensuring that the wire is completely shaped within the second shaping mold 520, thus guaranteeing the shaping effect of this embodiment.

[0052] It is understandable that if a third shaping mold, a fourth shaping mold, etc. are provided, the length of the third shaping mold and the fourth shaping mold can also be set arbitrarily according to actual needs, as long as the wire can be completely shaped after passing through the last shaping mold, thus ensuring the practicality of this embodiment and the flexibility of the usage process.

[0053] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0054] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
