[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figures 1-4 As shown.

[0027] A cable conductor repair device includes a mold sleeve 1 and a repair mold 2, wherein the repair mold 2 can be fixed inside the mold sleeve 1. The broken cable core can be repaired by the repair mold 2.

[0028] The mold sleeve 1 consists of an upper mold sleeve 11 and a lower mold sleeve 12, which can be connected to form a hollow cylinder. In this embodiment, the upper mold sleeve 11 occupies two-thirds of the overall size of the mold sleeve 1, and the lower mold sleeve 12 occupies one-third of the overall size of the mold sleeve 1. Fixing rods 121 are provided on both sides of the lower mold sleeve 12. The fixing rods 121 are located in the middle of the lower mold sleeve 12 and extend outwards at both ends in the horizontal direction. An arc asymptote is provided at the top of the fixing rods 121. A limiting rod 111 is provided at the top of the middle part of the upper mold sleeve 11. The limiting rod 111 is connected to the upper mold sleeve 11 by bolts. The upper mold sleeve 11 has a hole inside to accommodate the limiting rod 111. The bottom of the limiting rod 111 is threaded so that it can be fixed in the hole of the upper mold sleeve 11. The limiting rod 111 can pass through the interior of the upper mold sleeve 11.

[0029] The upper mold sleeve 11 and the lower mold sleeve 12 are connected by a slot 14, see reference. Figure 4 Both the upper mold sleeve 11 and the lower mold sleeve 12 have outwardly extending slots 14 on their connecting surfaces, and the extended slots 14 have the same structure. The slots 14 in the upper mold sleeve 11 can cooperate with the slots 14 in the lower mold sleeve 12 to connect, and the connected upper mold sleeve 11 and lower mold sleeve 12 form a mold sleeve 1, which is a hollow cylinder.

[0030] The assembled mold sleeve 1 forms a limiting flange 13 on one side of the hollow cylinder. The limiting flange 13 can limit the range and direction of movement of the repair mold 2 within the mold sleeve 1.

[0031] Reference Figure 2 , Figure 3The limiting flanges 13 are respectively arranged on one side of the upper die sleeve 11 and the lower die sleeve 12, and can form a complete ring when the upper die sleeve 11 and the lower die sleeve 12 are combined. In the lower die sleeve 12, the clamping groove 14 protrudes from one end of the lower die sleeve 12 and extends along the direction of the height of the cylinder; the limiting flange 13 arranged on the lower die sleeve 12 covers the protruding side of the clamping groove 14 of the lower die sleeve 12 as a whole. The limiting flange 13 arranged on the upper die sleeve 11 can be spliced with the limiting flange 13 arranged on the lower die sleeve 12 to form a ring. The minimum diameter of the ring is shorter than the minimum diameter of the hollow cylinder formed by the upper die sleeve 11 and the lower die sleeve 12, which can block the repair mold from passing through. The fixing rods 121 arranged at both ends of the lower die sleeve 12 are fixed to the two ends of the lower die sleeve 12 by welding, and both of the fixing rods 121 are in the same horizontal plane and perpendicular to the plane in which the limiting rod 111 is located.

[0032] With reference to Figure 1 The repair mold 2 is composed of two identical half molds, which can be fixed in the die sleeve 1 after being combined, and the limiting flange 13 arranged on the die sleeve 1 can block the repair mold 2 from passing through the die sleeve 1. The limiting rod 111 arranged on the top of the upper die sleeve 11 can limit the position of the repair mold 2 inside the die sleeve 1.

[0033] With reference to Figure 4 The structure of the half mold is shown in the figure, and the two half molds can form the repair mold 2 after being connected and matched with each other. The half mold is in an arch shape, and a protruding boss 23 is arranged at one end of the arch shape. The boss 23 is identical in shape to the half mold, and the maximum outer diameter of the boss 23 is smaller than that of the half mold. The half mold has two planes symmetrically arranged, a protrusion 22 is arranged on one of the planes, and a recess 21 is arranged on the other plane. The protrusion 22 is identical in shape to the recess 21, and the two half molds can form the repair mold 2 through the matching of the protrusion 22 and the recess 21. A circular arc asymptote is arranged on the side of the repair mold 2 away from the boss 23, which can assist the cable core needing repair to enter the repair mold 2. The repair mold 2 is in a hollow cylindrical shape, and can accommodate the cable core needing repair in the inside of the hollow cylinder to repair the broken cable core. The diameter of the outside of the repair mold 2 is the same as the inside diameter of the die sleeve 1, and the repair mold 2 can be fixed in the die sleeve 1. When the repair mold 2 is fixed in the die sleeve 1, the limiting rod 111 of the die sleeve 1 can be twisted to press the repair mold 2 in the die sleeve 1. The limiting flange 13 of the die sleeve 1 can limit the position and movement range of the repair mold 2 in the die sleeve.

[0034] During the repair process, the position of the die sleeve can be fixed by the fixing rod 121 to prevent the die sleeve from deviating during the repair of the cable.

[0035] A repairing method of a wire conductor repairing device, in the process of cable production, cable core breakage is inevitable, at this time, the broken cable core needs to be repaired.

[0036] In the process of repairing, the wire conductor repairing device needs to be used, and the specific steps are as follows:

[0037] Step 1, two half dies are connected and matched with each other through recesses 21 and protrusions 22 to form a repairing die 2; the upper die sleeve 11 and the lower die sleeve 12 are combined to form a die sleeve 1, and the fixed rod 121 controls and fixes the die sleeve 1.

[0038] Step 2: assemble the repairing die 2 into the die sleeve 1, and control the fixed rod 121 to fix the repairing die 2.

[0039] Step 3, the broken core inside the cable core is extracted during the production process, and one or more complete cores are selected, each complete core is fixed on each part of the broken cable core, and is fixed on the original core by welding, the welding is only welded in one place, and the welded core is passed through the repairing die 2.

[0040] In step 2, the fixed rod 121 can be fixed on the workbench, and the fixed rod 121 is fixed during the repair of the broken core, so as to avoid the offset during the repair process and affect the repair effect.

[0041] In step 3, the welded core is only connected with the core as a whole at one point, part of the core does not form a complete core with the core as a whole, that is, the welded core is easy to disperse, resulting in damage to the whole core. When the welded core passes through the repairing die 2, the repairing die 2 can extrude the welded core into the whole core, so as to ensure that the repaired core forms a complete and non-dispersed core.

[0042] In step 3, the core to be repaired enters the repairing die 2 from one side of the circular asymptote of the repairing die 2 (i.e. the side away from the boss 23), and leaves from the side of the boss 23 of the repairing die 2.

[0043] Two half dies are used in the repairing die 2, which can provide accurate guidance and fixation for cable repair, and can weave the welded core into a circle. The repairing die 2 is fixed in the die sleeve 1, the structure is stable, and the error caused by deviation or inaccuracy in manual repair is avoided.

[0044] The die sleeve 1 forms a limiting flange 13, and the repairing die 2 is provided with a boss 23 matched with the flange. The limiting flange 13 and the boss 23 cooperate to avoid the deviation of the die sleeve 1 during the repairing process, and the boss 23 can further enhance the fixing effect of the repairing die 1.

[0045] The fixing rods 121 are arranged on both sides of the die sleeve 1, and can stabilize the die sleeve 1 in the process of repairing the cable, so that deviation of the die sleeve 1 in the repairing process is avoided, and the overall working stability is improved.

[0046] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application.
