Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent warning cable manufacturing, and particularly relates to a core inlet stabilizing system. Background Art

[0002] During the production process of intelligent warning cables, a temperature measurement optical cable needs to be introduced for composite cabling in the cabling process. After this process, it is necessary to conduct on-off tests and attenuation tests on the optical unit, and these two tests are crucial. If the results of the on-off and attenuation tests do not meet the standards, it may indicate that there are defects in the functions of the intelligent warning cable such as signal transmission and monitoring of the ambient temperature change, which will seriously affect the ability of the intelligent warning cable to monitor the temperature change of itself and the surrounding environment in the actual use process, as well as the function of accurately locating the high-temperature area in case of a fire.

[0003] In the prior art, the pay-off process of the temperature measurement optical cable ensures the stability of the pay-off tension through a belt tension pay-off stand, and at the same time, the inside of the cabling die is polished to reduce friction. However, there is still a significant problem in the prior art: the temperature measurement optical cable is prone to position deviation at the inlet of the cabling die, resulting in abnormal extrusion of the temperature measurement optical cable by the cable, leading to unstable product quality or damage; the tension cannot be adjusted in real time according to the cable margin, which may cause the tension borne by the temperature measurement optical cable during cabling to exceed its mechanical strength limit, resulting in damage or breakage. This problem needs to be solved urgently to improve the overall performance and reliability of the intelligent warning cable. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the purpose of the present invention is to provide a core inlet stabilizing system.

[0005] In order to achieve the above purpose and achieve the above technical effects, the technical solution adopted by the present invention is as follows:

[0006] A core inlet stabilizing system includes:

[0007] A stabilizing plug for fixing the inlet position of the core and preventing the core from being damaged during cabling;

[0008] A highly wear-resistant bellmouth cabling die;

[0009] The stabilizing plug is adapted to the highly wear-resistant bellmouth cabling die, and the core passes through the stabilizing plug and penetrates into the highly wear-resistant bellmouth cabling die for cabling.

[0010] Furthermore, one end of the stabilizing tube is provided with a trumpet-shaped opening, and the other end opposite thereto is provided with a guide tube connected to the trumpet-shaped opening; the end of the guide tube away from the trumpet-shaped opening is provided with a limit block and a through-port adapted to a highly wear-resistant trumpet-shaped cabling mold; the wire core enters from the trumpet-shaped opening, passes through the guide tube and exits from the through-port.

[0011] Furthermore, a conical bell mouth is provided at the inlet end of the highly wear-resistant bell-mouth cabling mould, and the conical angle of the conical bell mouth matches the cabling angle. One end of the wear-resistant bell-mouth cabling mould on which the conical bell mouth is provided is also provided with a cylindrical hole adapted to a limit block. By inserting the limit block on the stabilizing tube into the cylindrical hole, the stabilizing tube and the highly wear-resistant bell-mouth cabling mould can be fixed together, thereby ensuring that the wire core's incoming position is accurate.

[0012] Furthermore, the cone angle α of the conical horn and the natural bending angle β of the cable core satisfy the following relationship: 2.5°≤|α-β|≤3.5°.

[0013] Furthermore, the length of the conical bell mouth is 50-70 mm.

[0014] Furthermore, the diameter of the cylindrical hole is 5.5-6.5 mm and the depth is 7.0-7.5 mm.

[0015] Furthermore, the surface of the highly wear-resistant bell-mouth cabling mold is provided with a carburized layer, a titanium nitride coating and a porous oxide layer in sequence from the inside to the outside, and the pores of the porous oxide layer are filled with nano-molybdenum disulfide particles.

[0016] Furthermore, the depth of the carburized layer is 0.8-1.2 mm; the thickness of the titanium nitride coating is 2-3 μm.

[0017] Furthermore, it also includes a numerically controlled magnetic powder tension pay-off stand, on which a reel is provided, and a wire core is wound on the reel.

[0018] Furthermore, the numerically controlled magnetic powder tension pay-off stand is provided with a control module, a tension detection module, a weight detection module and a tension wheel, and the control module is connected with the tension detection module, the weight detection module and the tension wheel, and the real-time weight of the reel is detected by the weight detection module and transmitted to the control module for processing, and the remaining amount of the wire core on the reel is judged, and the tension of the wire core is detected in real time by the tension detection module and transmitted to the control module for processing, and the tension wheel is controlled by the control module to dynamically adjust to the appropriate tension, so as to realize the closed-loop adjustment of the tension control;

[0019] The control module adjusts the pay-off tension according to the real-time weight data, and the tension calculation formula is:

[0020] Y = E × (A × X) + D

[0021] Among them, Y is the real-time tension value, E is the linear proportionality coefficient, A is the weight per unit length of the core wire, X is the real-time remaining length of the core wire, and D is the tension of the pay-off overhead reel.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

By designing a compatible stable insertion tube and a highly wear-resistant bell mouth stranding die, the core wire (mainly referring to the temperature measurement optical cable) can pass through the stable insertion tube and penetrate into the highly wear-resistant bell mouth stranding die to conduct subsequent stranding with other cables, which can ensure the accurate inlet position of the core wire, ensure the stability of the core wire during the stranding process, and avoid the core wire from being abnormally extruded by the cables, resulting in unstable product quality or damage. By designing a control module, a tension detection module, and a weight detection module, it is possible to realize real-time monitoring of the remaining amount of the core wire on the reel and the tension situation of the core wire. Through the control module, the tension wheel can be controlled to dynamically adjust to an appropriate tension to achieve closed-loop regulation of tension control, thereby ensuring the stability of the stranding quality, avoiding the tension borne by the core wire during the stranding process from exceeding its mechanical strength limit, resulting in damage or fracture, effectively solving the quality problems of intelligent warning cables during the production process. The overall structure is simple, the manufacturing cost is low, and it is suitable for industrial promotion and use. Description of the Drawings

[0029] The present invention will be elaborated in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0030] A brief overview of one or more aspects is given below to provide a basic understanding of these aspects. This overview is not an exhaustive survey of all contemplated aspects and is neither intended to identify key or decisive elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that follows.

[0031] As Figures 1-5 shown, a core inlet stabilizing system includes:

[0032] A stabilizing plug 1, one end of the stabilizing plug 1 is provided with a flared opening 2, and the opposite end is provided with a guiding tube 3 communicating with the flared opening 2. The core 4 (mainly referring to the temperature-measuring optical cable) penetrates through the flared opening 2, passes through the guiding tube 3 and exits from the outlet 5 of the guiding tube 3. The outlet 5 is arranged at one end of the guiding tube 3 far from the flared opening 2. A limiting block 7 adapted to the highly wear-resistant flared cable-forming die 6 is also arranged at one end of the guiding tube 3 far from the flared opening 2; by designing the stabilizing plug 1, the inlet position of the core 4 can be fixed to prevent the core 4 from being damaged during the subsequent cable-forming process;

[0033] A highly wear-resistant flared cable-forming die 6, its inlet end is provided with a conical flared opening 8. The design of this conical flared opening makes the cable-forming angle fit the die, optimizing the guiding performance of the core 4. The conical angle of the conical flared opening 8 matches the cable-forming angle, which can effectively reduce friction and prevent the core 4 from being pinched, improving the qualified rate of products. A cylindrical hole 9 adapted to the limiting block 7 is also arranged at one end of the highly wear-resistant flared cable-forming die 6 where the conical flared opening 8 is provided. By inserting the limiting block 7 into the cylindrical hole 9, the stabilizing plug 1 can be fixed to the highly wear-resistant flared cable-forming die 6, ensuring the accurate inlet position of the core 4 and enabling the core 4 to form the best inlet angle at the inlet of the highly wear-resistant flared cable-forming die 6; a cable-forming outlet 10 is arranged at the outlet end of the highly wear-resistant flared cable-forming die 6, and the core 4 exits from the cable-forming outlet 10 after being cabled with the cable;

[0034] A numerically controlled magnetic powder tension pay-off stand 11, which has the functions of rapid response and high-precision tension control and is suitable for the pay-off operation of the core 4; a control module, a tension detection module, a weight detection module and a tension wheel are arranged on the numerically controlled magnetic powder tension pay-off stand 11. The control module is connected to the tension detection module, the weight detection module and the tension wheel. The real-time weight of the coil is detected by the weight detection module and transmitted to the control module for processing to judge the remaining amount of the core on the coil placed on this pay-off stand. The tension received by the core is detected in real time by the tension detection module and transmitted to the control module for processing. The control module controls the tension wheel to dynamically adjust to an appropriate tension to achieve the closed-loop adjustment of tension control, thereby ensuring the stability of the cable-forming quality and being beneficial to improving production efficiency and product quality.

[0035] In some embodiments, the high wear-resistant bell-mouth cabling mold 6 is first subjected to ion carburizing treatment, and the depth of the carburized layer is 0.8-1.2 mm; then a 2-3 μm thick titanium nitride coating is deposited on the surface of the carburized layer by magnetron sputtering; finally, a micro-arc oxidation treatment is performed to form a porous oxide layer, and nano-molybdenum disulfide particles are injected into the pores of the porous oxide layer, thereby significantly improving the wear resistance of the high wear-resistant bell-mouth cabling mold 6 and extending its service life.

[0036] In some embodiments, the cone angle α of the conical flare 8 and the natural bending angle β of the cable core 4 satisfy: 2.5°≤|α-β|≤3.5°. This design can make the contact stress distribution between the cable core 4 and the conical flare 8 most uniform, thereby effectively avoiding stress concentration, and at the same time can reduce the friction coefficient between the two, thereby reducing the wear on the optical cable and improving the cable quality. If |α-β|>3.5° or <2.5°, the former will aggravate the wear on the cable core, and the latter will cause the cable core to deviate laterally, resulting in eccentricity in the cable.

[0037] In some embodiments, the cable can be paid out through a common pay-out frame or through a CNC magnetic powder tension pay-out frame 11 , and a flexible selection can be made according to actual needs.

[0038] In some embodiments, the length of the tapered flare 8 is 50-70 mm.

[0039] In some embodiments, the cylindrical hole 9 has a diameter of 5.5-6.5 mm and a depth of 7.0-7.5 mm, and is used in conjunction with the stable cannula 1 to ensure that the wire core 4 is in a stable position.

[0040] In some embodiments, the control module adjusts the pay-off tension according to the real-time weight data to achieve closed-loop precise control of the pay-off tension. The real-time tension calculation formula of the pay-off frame is:

[0041] Y=E×(A×X)+D

[0042] Among them, Y is the real-time tension value, E is the linear proportional coefficient, A is the weight of the wire core per meter, X is the real-time remaining length of the wire core, and D is the tension of the overhead wire reel.

[0043] In the present invention, when the tension of the CNC magnetic powder tension pay-off frame 11 disappears due to accidental factors, the stable insert tube 1 can ensure that the cabling position of the wire core 4 always remains in the optimal position, that is, located at the center position after the intersection of the two cables, and tangent to the two cables respectively, thereby effectively avoiding product quality problems caused by tension fluctuations.

[0044] By adopting a customized high-wear-resistant cable-forming die structure for the horn mouth, designing a stable inserting tube, and implementing high-precision tension control, the present invention effectively improves the production efficiency and product quality of the intelligent warning cable. The conical angle of the customized high-wear-resistant cable-forming die structure for the horn mouth is adapted to the cable-forming angle, thereby effectively reducing the friction coefficient between the core and the die and preventing the core from being pinched during the cable-forming process. The stable inserting tube ensures the position stability of the core during the cable-forming process, and the high-precision tension control ensures the stress uniformity of the optical unit during the manufacturing process. The synergistic effect of the above technical solutions significantly improves the on-off performance of the optical unit of the intelligent warning cable and effectively controls the attenuation characteristics, thereby greatly improving the passing rate of product detection.

[0045] For parts or structures not specifically described in the present invention, existing technologies or existing products can be used and will not be elaborated here.

[0046] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
