Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable production technology, and in particular to a continuous annealing device for cable production. Background Technology
[0002] Annealing is a metal heat treatment method that involves heating a metal material to a suitable temperature and then slowly cooling it to increase its toughness. In the processing and manufacturing of cables, annealing is a necessary process to ensure that the copper wire achieves the conductor properties required for the cable product. Currently, most annealing devices have inlets and outlets on both sides for the cable to pass through. However, these inlets and outlets are often open, causing heat to easily escape from the inlets and outlets during annealing, thus affecting the efficiency of heating the cable.
[0003] A Chinese patent (authorization announcement number CN211420265U) discloses a cable processing annealing device, which "includes a frame, a sealing door is installed on the front surface wall of the frame, a controller is installed on the upper end of the outer surface wall of the sealing door, a heater is installed on the upper end of the inner side of the frame, and a guide roller is installed inside the frame and below the heater."
[0004] It is evident that the cited patent document suffers from the problem of heat easily being lost from the inlet and outlet. Utility Model Content
[0005] The purpose of this invention is to provide a continuous annealing apparatus for cable production, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous annealing device for cable production, comprising an annealing box, with mounting boxes installed on both sides of the annealing box, and through holes for cables to pass through on both sides of the two mounting boxes. The inner walls of the two mounting boxes are rotatably connected to first bidirectional threaded rods via pins. Two first limiting plates are threadedly fitted around the periphery of each of the two first bidirectional threaded rods. The inner bottom surfaces of the two mounting boxes are also rotatably connected to second bidirectional threaded rods via pins. Second limiting plates are threadedly fitted around the periphery of each of the two second bidirectional threaded rods. An arc-shaped groove is provided on the opposite side of each pair of first limiting plates and the opposite side of each pair of second limiting plates. One end of each first bidirectional threaded rod and each second bidirectional threaded rod passes through the mounting box and is connected to a handle.
[0007] Preferably, the lower half of the inner sidewalls of both mounting boxes are welded with limit rods, and the two first limiting plates are slidably sleeved on the periphery of the limit rods.
[0008] Preferably, a sliding rod is welded to the inner top surface of both mounting boxes, and the two second limiting plates are slidably sleeved on the periphery of the sliding rod.
[0009] Preferably, a base is welded to both sides of the annealing box, and two upright plates are symmetrically welded to the top surface of each of the two bases.
[0010] Preferably, each pair of upright plates has two guide wheels rotatably connected to one of their opposite sides for guiding the cables through continuous annealing.
[0011] Preferably, a connecting box is installed on the inner top surface of the annealing box, and a plurality of heating wires for heating cables are installed in the inner cavity of the connecting box.
[0012] Preferably, the top surface of the annealing box is equipped with two blowers, and the bottom surface of the connecting box is connected to a plurality of air outlet pipes for conveying heat.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This continuous annealing device for cable production provides power for the rotation of the first and second bidirectional threaded rods by rotating two handles. This allows the movement of two first and two second limiting plates, thus restricting the inlet and outlet of the annealing chamber. Compared to existing devices for annealing cables, this device restricts the inlet and outlet of the annealing chamber, reducing heat loss from the chamber and improving the efficiency of cable annealing.
[0015] The welded limit rods and slide rods can restrict the movement trajectory of the two first limit plates and the two second limit plates, preventing deviation during their movement. The two rotatably connected guide wheels can assist the cable movement and, in conjunction with external traction equipment, perform continuous annealing treatment on the cable.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0027] like Figures 1 to 5 The continuous annealing apparatus for cable production shown includes an annealing chamber 1. An inlet slot and an outlet slot are respectively provided on two sides of the annealing chamber 1, so that the cable can enter the interior of the annealing chamber 1 through the inlet slot and exit through the outlet slot. A traction device (not shown) is connected to one side of the annealing chamber 1, so that the cable passing through the outlet slot can be connected to the external traction device, thereby driving the cable to move and thus performing continuous annealing.
[0028] The annealing box 1 is equipped with mounting boxes 2 on both sides. Both sides of the two mounting boxes 2 are provided with through holes 3 for cables to pass through. The positions of the multiple through holes 3 are aligned with the positions of the inlet groove and the outlet groove, so that after the cable passes through the through hole 3, it will pass through the inlet groove.
[0029] Both mounting boxes 2 have a first bidirectional threaded rod 4 rotatably connected to their inner walls via pins. Two first limiting plates 5 are threaded onto the periphery of each of the two first bidirectional threaded rods 4. Similarly, both mounting boxes 2 have a second bidirectional threaded rod 6 rotatably connected to their inner bottom surfaces via pins. Two second limiting plates 7 are threaded onto the periphery of each of the two second bidirectional threaded rods 6. Multiple first limiting plates 5 and multiple second limiting plates 7 are in frictional contact with the inner walls of both sides of the mounting box 2. The opposite sides of the multiple first limiting plates 5 and multiple second limiting plates 7 are also in frictional contact. Each pair of opposing sides of the first limiting plates 5 and each pair of opposing sides of the second limiting plates 7 are provided with an arc-shaped groove 8. After the cable passes through the through hole 3, rotating the first bidirectional threaded rod 4 will drive the two first limiting plates... The plate 5 moves in a relative direction, and at the same time the second bidirectional threaded rod 6 is rotated, so that the second bidirectional threaded rod 6 drives the two second limiting plates 7 to move in a relative direction. This allows the arc-shaped grooves 8 on one side of the two first limiting plates 5 and the two second limiting plates 7 to be as close as possible to the cable without affecting the movement of the cable. Since the multiple first limiting plates 5 and the multiple second limiting plates 7 are in frictional contact with the inner walls of both sides of the mounting box 2, and the opposite side of the multiple first limiting plates 5 and the multiple second limiting plates 7 are also in frictional contact, the first limiting plates 5 and the second limiting plates 7 can restrict the space of the inlet groove, the outlet groove and the cable periphery of the annealing box 1, reduce the loss of heat from the inlet groove and the outlet groove inside the annealing box 1, and improve the efficiency of cable annealing.
[0030] Each of the first bidirectional threaded rod 4 and the second bidirectional threaded rod 6 has a handle 9 connected to one end through the mounting box 2. By turning the handle 9, the operator can rotate the first bidirectional threaded rod 4 and the second bidirectional threaded rod 6.
[0031] Limiting rods 10 are welded to the lower half of the inner sidewalls of both mounting boxes 2. Both first limiting plates 5 are slidably sleeved on the periphery of the limiting rods 10. Both inner top surfaces of the mounting boxes 2 are welded with sliding rods 11. Both second limiting plates 7 are slidably sleeved on the periphery of the sliding rods 11. When multiple first limiting plates 5 and multiple second limiting plates 7 move, they will move on the periphery of the limiting rods 10 and sliding rods 11 respectively, which can limit the movement trajectory of multiple first limiting plates 5 and multiple second limiting plates 7 and prevent deviation.
[0032] The annealing box 1 has bases 12 welded on both sides. The top surfaces of the two bases 12 are symmetrically welded with two upright plates 13. Each pair of upright plates 13 has two guide wheels 14 rotatably connected to the opposite side for guiding the cable to perform continuous annealing. The multiple guide wheels 14 are also rotatably connected to the upright plates 13 through pins, allowing the cable to pass between the two guide wheels 14, thus assisting the cable in moving.
[0033] A connection box 15 is installed on the inner top surface of the annealing box 1. Multiple heating wires 16 for heating cables are installed inside the cavity of the connection box 15. Two blowers 17 are installed on the top surface of the annealing box 1. A through groove for air to pass through is provided on the top surface of the annealing box 1 and below the two blowers 17. Several air outlet pipes 18 for conveying heat are connected to the bottom surface of the connection box 15. By connecting the heating wires 16 to the power supply, the heating wires 16 generate heat. When the blowers 17 are turned on, air can be sent to the connection box 15, so that the heat can be blown into the annealing box 1 through the air outlet pipes 18, thereby heating the cables in the annealing box 1 and performing annealing treatment.
[0034] Working principle:
[0035] The continuous annealing apparatus used in cable production passes the cable through the inlet slot on one side of the annealing chamber 1 and out through the outlet slot, while simultaneously connecting to an external traction device. Rotating the handle 9 connected to the first bidirectional threaded rod 4 causes the first bidirectional threaded rod 4 to rotate, thereby moving the two first limiting plates 5 in opposite directions. Simultaneously, rotating the handle 9 connected to the second bidirectional threaded rod 6 causes the two second limiting plates 7 to move in opposite directions, allowing the two first limiting plates 5 and the two second limiting plates 7 to be as close to the cable as possible. One limiting plate 5 and two second limiting plates 7 respectively rub against the inner walls of both sides of the mounting box 2, and the two first limiting plates 5 and the two second limiting plates 7 rub against each other, so that the first limiting plates 5 and the second limiting plates 7 can restrict the space of the inlet slot, outlet slot and the cable periphery of the annealing box 1. At this time, the blower 17 is turned on and the heating wire 16 is energized, so that the blower 17 can blow the heat generated by the heating wire 16 into the annealing box 1 through the air outlet pipe 18 to anneal the cable, reduce the loss of heat from the inlet slot and outlet slot inside the annealing box 1, and improve the efficiency of cable annealing.
