Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing technology, and in particular to a cable drawing and annealing device. Background Technology
[0002] Cable drawing and annealing are crucial processes in cable manufacturing, significantly impacting cable performance.
[0003] The stretching process improves the grain structure of the metal wire, enhancing its fatigue performance and ductility. Therefore, the stretched wire exhibits better mechanical strength and ductility. Annealing further relieves stress, improving the wire's machinability and facilitating subsequent cable processing.
[0004] In existing technologies, the inlet and outlet ends of traditional annealing equipment are usually located on different sides, which requires the wire to be routed around the outside of the equipment, increasing the equipment footprint and making the production line layout less compact, thus affecting the space utilization of the workshop. Annealing equipment often uses a single immersion oil cooling or spray cooling method, which can easily lead to inconsistent cooling rates of the wire, local overheating or insufficient cooling, thereby affecting the mechanical properties and surface quality of the wire. Therefore, we propose a cable drawing annealing device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable drawing and annealing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

An oil storage tank is fixedly connected inside the insulating box, and four steering wheels are rotatably connected inside the oil storage tank. A circulation pump is fixedly connected to the outer wall of the insulating box. Two through holes are formed in the outer wall of the insulating box, and the same U-shaped tube is fixedly connected to the inner wall of the two through holes. Multiple atomizing oil nozzles are uniformly fixed and interconnected at the bottom of the U-shaped tube. A wire-passing groove is formed at the top of the oil storage tank. A wire-guiding wheel is rotatably connected inside the insulating box, and a recycling component is provided on the outer wall of the insulating box.
[0008] Preferably, the recycling component includes an extraction pipe, one end of which is fixedly connected to the outer wall of the insulation box, and a centrifugal fan is fixedly connected to one end of the extraction pipe.
[0009] Preferably, the outer wall of the insulating box has two rectangular holes, and the inner walls of the two rectangular holes are respectively fixedly connected to the outer walls of two conductive copper sheets.
[0010] Preferably, one end of the U-shaped tube is fixedly connected to the output end of the circulating pump, and the input end of the circulating pump is fixedly connected to the outer wall of the oil storage tank.
[0011] Preferably, the outer wall of the insulation box has a circular hole, and the inner wall of the circular hole is fixedly connected to the outer wall of the input end of the circulating pump.
[0012] Preferably, the bottom of the insulation box is fixedly connected to four legs, and the outer wall of the insulation box is hinged with a protective door.
[0013] Preferably, the outer wall of the insulation box has two wire holes.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] This solution adopts a design with wires entering and exiting on the same side, avoiding the problem of wire detours in traditional equipment, significantly reducing the equipment footprint, improving the compactness of the production line layout, and optimizing workshop space utilization. Two electrode wheels preheat the wire to improve temperature uniformity. Finally, electromagnetic induction heating is used, which is fast and efficient, avoiding the localized overheating problem of traditional resistance heating.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Depend on Figures 1-4 As shown, a cable drawing and annealing device is disclosed, comprising an insulating box 1 with a double-layer stainless steel structure. The inner layer is filled with high-temperature resistant ceramic fiber insulation material to effectively prevent heat loss and ensure operational safety. Two electrode wheels 2 are fixedly connected inside the insulating box 1. The electrode wheels 2 are made of high-purity graphite material and coated with an anti-oxidation silver layer to ensure good conductivity and wear resistance. Conductive copper sheets 3 are fixedly connected to the outer walls of both electrode wheels 2. Two rectangular holes are opened on the outer wall of the insulating box 1. The inner walls of the two rectangular holes are fixedly connected to the outer walls of the two conductive copper sheets 3 respectively. The inner walls of the two rectangular holes are fixedly connected to the outer walls of the two conductive copper sheets 3 respectively through a waterproof and dustproof crimping process to ensure the reliability of the electrical connection.
[0024] Inside the insulation box 1, two guide wheels 4 are rotatably connected by existing bearings. The surface of the guide wheels 4 is covered with a polyurethane wear-resistant layer to effectively reduce wire wear. Inside the insulation box 1, two wire sleeves 5 are fixedly connected, and an induction coil 6 is fixedly connected between the two wire sleeves 5. The induction coil 6 is made of water-cooled copper tube and is connected to an external medium frequency power supply to achieve precise temperature control.
[0025] An oil storage tank 7 is fixedly connected inside the insulation box 1. Four steering wheels 8 are rotatably connected to the existing bearings inside the oil storage tank 7. The surface of the steering wheels 8 is treated with Teflon coating to reduce the coefficient of friction. A circulation pump 9 is fixedly connected to the outer wall of the insulation box 1. A circular hole is opened on the outer wall of the insulation box 1. The inner wall of the circular hole is fixedly connected to the outer wall of the input end of the circulation pump 9.
[0026] The outer wall of the insulation box 1 has two through holes, and the inner wall of the two through holes is fixedly connected to the same U-shaped tube 10. One end of the U-shaped tube 10 is fixedly connected to the output end of the circulation pump 9, and the input end of the circulation pump 9 is fixedly connected to the outer wall of the oil storage tank 7. Multiple atomizing oil nozzles 11 are evenly fixedly connected to the bottom of the U-shaped tube 10. The multiple atomizing oil nozzles 11 are located above the steering wheel 8. The atomizing oil nozzles 11 adopt a fan-shaped spray design with a spray angle of 60 degrees to ensure uniform cooling of the wire surface.
[0027] The top of the oil tank 7 is provided with a wire trough 12. The existing bearing inside the insulation box 1 is rotatably connected to the wire guide wheel 13. The bottom of the insulation box 1 is fixedly connected with four legs 15. The legs 15 are equipped with shock-absorbing rubber pads to ensure stable operation of the equipment. The outer wall of the insulation box 1 is hinged with a protective door 16. The inside of the door is provided with a high-temperature resistant observation window. The outer wall of the insulation box 1 has two wire shaving holes.
[0028] The outer wall of the insulation box 1 is equipped with a recycling component, which includes an exhaust pipe 14. One end of the exhaust pipe 14 is fixedly connected to the outer wall of the insulation box 1, and a centrifugal fan is fixedly connected to the other end of the exhaust pipe 14. An existing activated carbon filter layer and an oil mist separator are installed inside the exhaust pipe 14, which can effectively recycle and treat the oil mist and exhaust gas generated during the quenching process, ensuring a clean and environmentally friendly working environment.
[0029] Working principle: During use, the drawn wire enters the insulation box 1 through the wire-passing hole on the upper left outer wall of the insulation box 1, passes through two electrode wheels 2, two wire-passing sleeves 5, induction coils 6, two guide wheels 4 in sequence, then through the wire-passing groove 12 and four steering wheels 8, and finally exits from the wire-laying wheel 13 and another wire-passing hole. Finally, it is wound and collected by existing traction equipment. Since the wire-in direction is the same as the wire-out direction, there is no need to detour, which can reduce the space occupied by the equipment during use. In addition, during the annealing process, the two electrode wheels 2 provide current to the external power supply through the conductive copper sheet 3 connected to them to preheat the wire. After processing, the preheated wire enters the induction coil 6 through the right guide wheel 4, where it is heated by the induction coil 6. The heated wire then enters the oil tank 7, where the quenching oil is pumped from the oil tank 7 into the U-shaped tube 10 by the operation of the circulating pump 9. The oil is then sprayed downwards by multiple atomizing nozzles 11. The atomized quenching oil contacts the outer wall of the wire and cools it. After the wire is pre-cooled, it is then immersed in the quenching oil for secondary cooling by the upper and lower sets of steering wheels 8. The cooled wire passes through the wire threading groove 12 and is discharged from the wire threading hole on the lower left outer wall of the insulation box 1 by the wire guide wheel 13.
[0030] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the electrode wheel 2, induction coil 6, circulating pump 9, and centrifugal fan to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is merely to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.
