At the same time, a large number of special production equipment are required, which increases production costs and production cycles.
[0003] Specifically, if Figure 5 As shown, in the traditional manufacturing process of railway signal cable core bundles, the conductors first need to undergo a drawing annealing process to achieve the required size and performance; then, the conductors need to be individually insulated and extruded to cover each conductor with an insulating layer; then, the insulated single wires need to be twisted through a star-twisting process to form a wire group; finally, after a cabling process, multiple wire groups are wound and formed into a cable core bundle.
[0004] This traditional production method has the following problems:
[0005] Complex process: Each process requires independent equipment and operation, which makes the entire production process complicated and cumbersome.
[0006] Unable to produce continuously: Since the various processes cannot be directly connected, production cannot be carried out continuously, which reduces production efficiency.
[0007] Large equipment investment: Each process requires dedicated production equipment, which leads to large equipment investment and increased production costs.
[0008] Long production cycle: Due to the discontinuity between processes and the transfer time between equipment, the entire production cycle is long. Utility Model Content

[0013] The cable core bundle production device comprises a core belt conveying assembly, a cable core bundle clamping die, a cable bundle sizing die, a wrapping shaping device and a collecting device which are arranged in sequence;

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0033] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.
[0034] like Figure 1 and Figure 2 As shown, the railway signal cable core bundle manufacturing equipment of the utility model is characterized in that it includes a core band production device for producing an insulating core band, and a cable core bundle production device for molding the insulating core band into a cable core bundle;
[0035] The core strip production device comprises a conductor conveying assembly 1, a conductor preheater 2, an insulating film coating mechanism 3, a hot roll forming machine 4 and a blister device 5 which are arranged in sequence;
[0036] After the conductor conveying assembly 1 conveys a plurality of conductors side by side to the conductor preheater 2 for preheating, the insulating film coating mechanism 3 covers the preheated conductors with insulating film and hot-rolls the conductors into the blister device 5 by a hot roller forming machine 4 to form an insulating wire core tape; the conductor is preheated in the conductor preheater 2 to improve the adhesion between the insulating film and the conductor, and the preheated conductor enters the insulating film coating mechanism 3, which evenly covers the insulating film on the surface of the conductor, and the conductor covered with the insulating film then enters the hot roller forming machine 4, and the insulating film and the conductor are tightly combined by hot rolling to form an insulating wire core tape; finally, the insulating wire core tape enters the blister device 5 for further molding to ensure that the shape and size of the insulating wire core tape meet the requirements.
[0037] The cable core bundle production device comprises a core belt conveying assembly 6, a cable core bundle clamping mold 7, a cable bundle sizing mold 8, a wrapping shaping device 9 and a collecting device 10 which are arranged in sequence;
[0038] The core tape conveying assembly 6 conveys the insulating wire core tape to the cable core bundle mold 7 for winding and closing, and after the diameter is determined by the cable bundle sizing mold 8, it is shaped into a cable core bundle by the wrapping and shaping device 9 and is pulled and unloaded by the receiving device 10. The formed insulating wire core tape is conveyed to the cable core bundle production device through the core tape conveying assembly 6. In the cable core bundle mold 7, the insulating wire core tape is wound and molded to form a preliminary cable core bundle structure; then, the cable bundle enters the cable bundle sizing mold 8. Through the precise control of the sizing mold, it is ensured that the diameter and shape of the cable core bundle meet the specified requirements. Then, the cable core bundle is shaped by the wrapping and shaping device 9 to enhance the structural stability and tensile strength of the cable core bundle. The shaped cable core bundle is pulled by the receiving device 10 to complete the unloading process to form the final railway signal cable core bundle product.
[0039] As an implementation mode, the core strip production device further includes an air cooling device 11 and a spark detection device 12 arranged behind the blister device 5 .
[0040] After the insulating wire core tape is formed by the blister device 5, the air cooling device 11 will quickly cool the formed insulating wire core tape. The cooling process not only helps to maintain the shape and dimensional stability of the insulating wire core tape, but also improves production efficiency because the cooled insulating wire core tape can enter the next process more quickly.
[0041] Spark detection devices are mainly used to detect whether the insulation layer of insulated wire core tapes is damaged or the conductor is exposed during the manufacturing process, which may lead to electrical performance degradation or safety hazards. Through detection, defective products can be discovered and eliminated in time to ensure the quality of insulated wire core tapes.
[0042] In addition, the core tape production device further includes an insulated wire core tape winding device 13 arranged behind the spark detection device 12 .
[0043] The device reels the insulating wire core tape according to a certain length or weight, which is convenient for subsequent storage, transportation and use. At the same time, through the reeling operation, the insulating wire core tape can also be compressed and arranged to a certain extent, further improving its appearance and performance.
[0044] As an embodiment, the cable core bundle production device also includes a cable core bundle loading machine 16 arranged behind the collecting device 10. The cable core bundle loading machine 16 is mainly responsible for automatically loading the cable core bundle pulled out of the cable core bundle production device by the collecting device 10 for subsequent storage, transportation and further processing.
[0045] As an implementation method, Figure 3 and Figure 4 As shown, the insulating wire core tape comprises a plurality of conductors 14 which are continuously arranged at equal intervals, and an insulating film 15 which is coated on the outside of the conductors 14. The cable bundle is formed by winding the insulating wire core tape.
[0046] In this embodiment, by redesigning the structure of the signal cable, a new cable core production and processing method is adopted to solve the problems of complexity and lack of continuity in the traditional process. Specifically, the insulating wire core tape in this embodiment is composed of a plurality of conductors 14 arranged continuously at equal intervals and an insulating film 15 wrapped around the conductors. Subsequently, these insulating wire core tapes are processed into cable bundles by winding and forming.
[0047] The main advantages of this new processing method are:
[0048] Simplified process: By adopting the method of one-time pressing and then constraining, the traditional star-twisting process is eliminated, making the entire production process simpler and reducing the complexity of production.
[0049] Improve continuity: Due to the adoption of a continuous production process, the entire process from the production of insulating wire core tape to the forming of cable bundles can be carried out continuously and uninterruptedly, greatly improving production efficiency.
[0050] High flexibility: Regardless of the number of insulated cores or the number of wire groups, this new processing method can quickly merge them through one-time molding, which has strong flexibility and adaptability.
[0051] Improve product quality: Through continuous production processes and simplified process steps, the impact of human operations on product quality can be reduced and product stability and reliability can be improved.
