Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a continuous annealing device for cable production. Background Art

[0002] Annealing is a metal heat treatment method that heats the metal material to an appropriate temperature and then slowly cools it to increase the toughness of the metal. During the processing and manufacturing of cables, they need to undergo annealing process so that the copper wire can achieve the conductor performance required by cable products. Therefore, corresponding annealing equipment is needed.

[0003] The prior art publication number is CN216287739U, which discloses a continuous annealing device for cable production, comprising a device body, an annealing box, a heating box, an electric heating wire, and an induced draft fan. The annealing box is fixed to the top of the device body, the heating box is fixed to the center of the top of the annealing box, the electric heating wire is installed inside the heating box, the bottom of each heating box is installed with air outlet pipes at equal intervals, the top of the annealing box is fixed with an air collecting hood, the induced draft fan is installed on one side of the air collecting hood, a pressure relief box is fixed to the outer wall of the annealing box below the inlet and outlet hoods, a telescopic rod is installed on the inner wall of one side of the pressure relief box, and a push plate is fixed to the output end of the telescopic rod, and a sealing plug is fixed to the outer wall of one side of the push plate. The utility model not only realizes the automatic pressure relief function, improves the thermal effect inside the annealing box, and reduces energy consumption, but also supports and guides the cable, ensuring the straightness of the cable during annealing.

[0004] However, the above patent still has certain disadvantages when used: it recycles the hot air ejected from the air outlet pipe through the induced fan, but the heat will be lost in the process of circulation, which causes the upper and lower surfaces of the copper wire to receive different amounts of heat, resulting in uneven heating, which in turn affects the overall annealing quality. In addition, the hot air ejected from the air outlet pipe and the air outlet will directly act on the upper and lower surfaces, but cannot fully act on the side surfaces of the copper wire, thereby aggravating the uneven heating phenomenon, and the overall use effect is not very ideal.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

In order to ensure a sufficient amount of gas, the area where the flow holes 24 on the surface of the annealing tube 12 are located can also be opened up so that the heating disk 4 is in direct contact with the gas chamber 13. The specific form can be selected according to personnel needs.

[0031] In one embodiment, a heating box 6 is fixedly installed at the top position inside the annealing box 1, and an air guide pipe 9 is installed on the top of the heating box 6. One end of the air guide pipe 9 is connected to the blower 16. The blower 16 is located at the top surface position of the annealing box 1. An electric heating wire 7 is installed in the middle position inside the heating box 6. The bottom surface position of the heating box 6 is connected to the air supply pipe 5 through a pipeline. The air supply pipes 5 are symmetrically connected at both sides of the bottom of the air supply plate 10. The bottom end of the air supply pipe 5 is connected to the heating plate 4. The bottom surface position of the air supply plate 10 is symmetrically welded with connecting rods 11, and the bottom end of the connecting rod 11 is welded to the carrying ring 14.

[0032] In one embodiment, support legs 20 are symmetrically installed on both sides of the bottom of the annealing box 1. The support legs 20 can fix the entire device to enhance the overall stability in use.

[0033] In one embodiment, a wire cover 17 is symmetrically installed in the middle position of the two side surfaces of the annealing box 1, and guide wheels 18 are symmetrically installed at both ends of the wire cover 17. One end of the guide wheel 18 is connected to a driving device.

[0035] In one embodiment, a cavity is provided in the middle of the surface of the heating plate 4 for the copper wire of the cable to pass through. The setting of the cavity facilitates the passage of the copper wire of the cable, thereby ensuring that the copper wire can smoothly enter the annealing cylinder 12 for annealing operation.

[0036] In one embodiment, an annular protrusion is provided on the surface of the annealing cylinder 12 for rotatably connecting with the carrying ring 14 .

[0037] In one embodiment, a groove is provided on the surface of the carrying ring 14 for the rotation of the annealing tube 12 . The groove is provided to assist the rotation of the annealing tube 12 on the one hand, and to limit the annealing tube 12 on the other hand.

[0038] Working principle: In actual use, the guide wheel 18 can be connected to the driving device, so that the cable copper wire between the two sets of guide wheels 18 can smoothly enter the conveying operation. At this time, the cable copper wire can be in the internal position of the annealing cylinder 12. At this time, the operation of the brake motor 22 can drive the driving gear 23 to rotate, and the driving gear 23 can drive the driving shaft 3 connected thereto to rotate. The rotation of the driving shaft 3 can drive the gear plates 19 on both sides thereof to rotate, and the gear plates 19 can drive the transmission gear 8 meshing therewith to rotate. Since the transmission gear 8 is fixedly set on the surface of the annealing cylinder 12, it can drive the annealing cylinder 12 to perform corresponding rotation operations when it moves, so that the hot air ejected from the nozzle 15 on its surface can evenly act on the surface position of the copper wire, thereby improving the heating uniformity of the copper wire, so that the overall annealing effect can be improved, and the quality of use caused by surface temperature differences can be avoided. Moreover, while the above structure is running, through The blower 16 can continuously introduce external gas into the heating box 6 through the air guide pipe 9. At this time, the air entering the heating box 6 can come into contact with the high-temperature electric heating wire 7, thereby realizing the air heating operation. Then the high-temperature gas can enter the internal position of the heating disk 4 through the gas supply pipe 5. Since the heating disk 4 and the annealing cylinder 12 are rotatably connected to each other, and the heating disk 4 is fixedly installed on the surface position of the annealing box 1, the annealing cylinder 12 will not drive it to rotate when it rotates. The gas entering the heating disk 4 can enter the gas cavity 13 inside the annealing cylinder 12 through the flow hole 24, and finally be ejected from the nozzle 15 to realize the annealing operation of the copper wire with high-temperature gas. Since the high-temperature gas is introduced from the same place, there will be no large temperature difference, and the heat that finally acts on the surface of the copper wire is also relatively balanced, and there will be no large temperature difference, thereby ensuring the overall annealing effect and improving the quality of the product. The device as a whole has the advantages of uniform heating, comprehensive heating and good annealing effect.
