AI Technical Summary
When producing small-section cables, leakage is prone to occur during the winding process of steel belts. The cable is unevenly tensile due to the steel belt, and the sizing die is far away from the winding position, resulting in a large swing of the cable, which in turn causes the steel belt to leak.
A small-section steel belt armored cable production device is designed. By setting a sleeve in the mandrel, the sizing die can slide forward and backward along the mandrel. The spacing between the sizing die and the wrapping point is adjusted according to different cable conditions, reducing the cable swing amplitude, and ensuring the uniformity of the steel belt cover.
By reducing the cable swing amplitude, the upper and lower tension of the steel belt is equal, avoiding leakage of the bag, and improving the yield of the bag. At the same time, the device structure is simple, easy to use and strong practicality.

Technical Field
[0001] The utility model relates to the field of cable armor wrapping, in particular to a production device for small-section steel tape armored cables. Background Art
[0002] In the cable production process, a steel tape armor layer is added outside the insulated conductor core. The steel tape armor can effectively prevent the cable from being affected by the external environment, such as mechanical damage, wet oxygen, etc., thereby extending the service life of the cable. Therefore, the steel tape armor is widely used in the cable production process.
[0003] When the company produces small-section cables, the steel tape wrapping process is prone to missing wrapping. According to the production process requirements, the two layers of steel tapes should overlap each other, and missing wrapping is not allowed. After analysis, the wrapping device of the steel tape armored machine has the following problems: ① When producing small-section cables, the cable is unevenly stressed by the steel tape during the steel tape wrapping process; ② The sizing die is far from the steel tape wrapping position, and the large swing of the cable causes missing wrapping of the steel tape.
[0004] Therefore, those skilled in the art are committed to developing a production device for small-section steel tape armored cables that can reduce the swing amplitude of the cable and improve the qualified rate of wrapping. Summary of the Utility Model
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the utility model is to provide a production device for small-section steel tape armored cables that can reduce the swing amplitude of the cable and improve the qualified rate of wrapping.

[0007] Preferably, a first through hole extending axially is opened on the sizing die, and the first through hole coincides with the axis of the sleeve.
[0008] Preferably, both ends of the sleeve extend out of the core shaft respectively.
[0009] Preferably, a front support ring and a rear support ring are respectively arranged at both ends of the core shaft, one end of the sleeve is inserted into the front support ring, and the relative other end is inserted into the rear support ring.

[0021] As Figures 1-4As shown in the figure, a production device for small cross-section steel tape armored cables includes a core shaft 1, which is integrated with a wrapping machine. A sleeve 2 is sleeved inside the core shaft 1. Both ends of the sleeve 2 extend out of the core shaft 1, and sufficient lengths are reserved at both ends to ensure that the sleeve 2 will not slide into the core shaft 1. The sleeve 2 is in sliding fit with the core shaft 1, for example, achieved by clearance fit. A sizing die 3 is provided at one end of the sleeve 2. The sizing die 3 is fixed to the sleeve 2 by screws. An axially extending first through hole 4 is opened on the sizing die 3 for the cable 9 to pass through. The first through hole 4 coincides with the axis of the sleeve 2, which is convenient for reducing the swinging amplitude of the cable 9. The sizing die 3 can be separated from the center, which is convenient for installation and disassembly. During use, the sleeve 2 is pushed, and the sizing die 3 moves synchronously with the sleeve 2. When facing cables 9 of different thicknesses and types, the distance between the sizing die 3 and the wrapping point can be adjusted by moving the sleeve 2, and finally, a suitable position is selected for fixation, so as to reduce the swinging amplitude of the cable 9, make the upper and lower pulling forces of the cable 9 on the steel tape 8 equal, thus ensuring uniform overlapping of the steel tape 8 and improving the wrapping yield rate.
[0022] In this embodiment: front support rings 5 and rear support rings 6 are respectively arranged at both ends of the shown core shaft 1. The axes of the front support ring 5 and the rear support ring 6 coincide, which is convenient for reducing the swinging amplitude of the cable 9 and improving the stability of the sleeve 2. The front support ring 5 and the rear support ring 6 are respectively connected to both ends of the core shaft 1 by screws. One end of the sleeve 2 is inserted into the front support ring 5, and the relative other end is inserted into the rear support ring 6. Both ends of the sleeve 2 are in sliding fit with the front support ring 5 and the rear support ring 6 respectively. Friction plates can be arranged on the inner side walls of the front support ring 5 and the rear support ring 6. The friction plates can be made of materials such as PCM and Teflon. During use, the sleeve 2 can be pushed to slide back and forth along the front support ring 5 and the rear support ring 6.
[0023] In this embodiment: a second through hole 7 is opened on the side wall of the rear support ring 6. A fastening bolt is threadedly connected in the second through hole 7. The fastening bolt can move up and down along the second through hole 7. When the fastening bolt moves down, the bottom of the fastening bolt abuts against the sleeve 2, playing a limiting role on the sleeve 2. When the fastening bolt is moved up, the bottom of the fastening bolt is separated from the sleeve 2, and the sleeve 2 is unlocked.
[0024] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
