Technical Field

[0001] This utility model relates to the field of copper rod annealing technology, specifically to an annealing device for softening copper rods. Background Technology

[0002] A copper rod annealing apparatus is a device used for heat treatment of copper rods. Its main purpose is to improve the internal structure of the copper rod through heating and holding at a certain temperature, thereby enhancing its mechanical properties and electrical conductivity. The annealing process can eliminate internal stresses generated during cold working of the copper rod, improving its plasticity and toughness.

[0003] CN220450241U discloses a copper rod heat treatment annealing furnace, including a furnace body and an insulating lining. Stabilizing grooves are fixedly formed on the inner top and bottom walls of the furnace body, and placement grooves are fixedly formed on both inner side walls of the furnace body. An installation plate is fixedly connected to one side of the furnace body, and a motor is fixedly installed on the installation plate. A first pulley is fixedly connected to the output end of the motor, and a first belt is rotatably connected to the first pulley. Rotating rods are rotatably connected to both sides of the furnace body, and a second pulley is fixedly connected to one of the rotating rods. A gear is fixedly connected to one side of each rotating rod, rotatably passing through the side wall of the furnace body. A second belt is rotatably connected to the second pulley. This invention uses a motor to mechanically remove or install the insulating lining, eliminating the need for manual labor, reducing worker fatigue, and making it convenient to use.

[0004] The aforementioned patent addresses the shortcomings of existing copper rod heat treatment annealing furnaces, which typically use bolts and nuts to fix the insulation lining inside the furnace body. This is because if the insulation lining is damaged and needs maintenance or replacement, workers must enter the furnace body to remove the bolts and nuts one by one before the insulation lining can be taken out, which is extremely inconvenient. This application provides another implementation scheme to address the problems raised in the aforementioned patent. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an annealing device for softening copper rods, which has the advantage of facilitating the replacement and maintenance of the insulation lining. It solves the problem that in existing copper rod heat treatment annealing furnaces, the insulation lining is usually fixed inside the furnace body using bolts and nuts. Once the insulation lining is damaged and needs maintenance or replacement, workers need to enter the furnace body to remove the bolts and nuts one by one before the insulation lining can be taken out, which is extremely inconvenient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an annealing device for softening copper rods, comprising an annealing furnace body and a heat insulation cover, wherein a connecting mechanism is provided between the annealing furnace body and the heat insulation cover;

[0007] The connecting mechanism includes two U-shaped grooves fixedly installed on the surface of the annealing furnace body. A hollow cylinder is fixedly installed on the surface of the U-shaped groove. A top spring is fixedly installed inside the hollow cylinder. A connecting block is fixedly installed on the top of the top spring. A fixing pin extending to the inside of the U-shaped groove is fixedly installed on the surface of the connecting block. Two L-shaped connecting plates are fixedly installed on the surface of the heat insulation cover. A strip groove is opened on the surface of the L-shaped connecting plate. A fixing groove is opened on the inner surface of the strip groove.

[0008] Furthermore, the heat insulation cover has a U-shaped cross-section, and the inner shape and size of the heat insulation cover are adapted to the outer shape and size of the annealing furnace body.

[0009] Furthermore, the connecting block is adapted to the hollow cylinder, and there is a sliding contact between the surface of the connecting block and the inner surface of the hollow cylinder.

[0010] Furthermore, a tie rod extending to the outside of the hollow cylinder is fixedly installed on the surface of the connecting block, and the tie rod is in sliding contact with the hollow cylinder.

[0011] Furthermore, the width of the groove is greater than the diameter of the fixing pin, and the fixing pin is adapted to the fixing groove.

[0012] Furthermore, a guide rail is fixedly installed inside the U-shaped groove, and a strip-shaped mounting groove is opened on the surface of the L-shaped connecting plate. A number of pulleys adapted to the guide rail are rotatably installed inside the strip-shaped mounting groove.

[0013] Furthermore, resistance wire heaters are fixedly installed on opposite sides of the interior surface of the annealing furnace body, an infrared microwave heater is fixedly installed on the upper interior surface of the annealing furnace body, and a controller is fixedly installed on the top surface of the annealing furnace body.

[0014] Furthermore, one end of the U-shaped groove is an open structure, and the other end is a closed structure.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. This annealing device for softening copper rods achieves a tight connection between the insulation cover and the annealing furnace body by placing the insulation cover outside the furnace body and using a top spring, fixing pin, and fixing groove. Compared with the bolt and nut fixing method in the prior art, this device eliminates the need for workers to enter the furnace body to disassemble the bolts one by one, greatly improving the disassembly and assembly efficiency and saving time and labor costs. At the same time, the guide rail and pulley design allows the insulation cover to move smoothly during disassembly and assembly, enhancing the adaptability and flexibility of the device and facilitating the maintenance and replacement of the insulation cover.

[0017] 2. This annealing device for softening copper rods uses a resistance wire heater and an infrared microwave heater installed inside the annealing furnace body. The two work together to achieve precise control of the annealing temperature. The resistance wire heater provides stable basic heating, while the infrared microwave heater uses the penetrating power of microwaves to quickly heat the inside of the copper rod, which helps to improve annealing efficiency. At the same time, precise temperature control helps to reduce energy consumption. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4An annealing apparatus for softening copper rods in this embodiment includes an annealing furnace body 1 and a heat insulation cover 2. The heat insulation cover 2 has a U-shaped cross-section, and its inner shape and size are adapted to the outer shape and size of the annealing furnace body 1, facilitating the fitting of the heat insulation cover 2 onto the outer surface of the annealing furnace body 1. A connecting mechanism is provided between the annealing furnace body 1 and the heat insulation cover 2. The connecting mechanism includes two U-shaped grooves 3 fixedly installed on the surface of the annealing furnace body 1. A hollow cylinder 4 is fixedly installed on the surface of the U-shaped groove 3. A top spring 5 is fixedly installed inside the hollow cylinder 4. A connecting block 6 is fixedly installed on the top of the top spring 5. The connecting block 6 is adapted to the hollow cylinder 4, and the surface of the connecting block 6 slides in contact with the inner surface of the hollow cylinder 4, facilitating the connection block 6 within the hollow cylinder. 4. Internal movement: A fixing pin 7 extending to the inner side of the U-shaped groove 3 is fixedly installed on the surface of the connecting block 6. A pull rod 11 extending to the outside of the hollow cylinder 4 is fixedly installed on the surface of the connecting block 6. The pull rod 11 slides in contact with the hollow cylinder 4. The pull rod 11 facilitates the movement of the connecting block 6 and the fixing pin 7. Two L-shaped connecting plates 8 are fixedly installed on the surface of the heat insulation cover 2. One end of the U-shaped groove 3 is an open structure, and the other end is a closed structure, which can limit the L-shaped connecting plate 8. A strip groove 9 is opened on the surface of the L-shaped connecting plate 8. A fixing groove 10 is opened on the inner surface of the strip groove 9. The width of the strip groove 9 is greater than the diameter of the fixing pin 7. The fixing pin 7 is adapted to the fixing groove 10, which facilitates the fixing pin 7 to be inserted into the fixing groove 10.

[0025] A guide rail 12 is fixedly installed inside the U-shaped groove 3. A strip-shaped mounting groove 13 is opened on the surface of the L-shaped connecting plate 8. A number of pulleys 14 adapted to the guide rail 12 are rotatably installed inside the strip-shaped mounting groove 13. By setting the guide rail 12 and the pulleys 14, the L-shaped connecting plate 8 can be moved inside the U-shaped groove 3.

[0026] Resistance wire heaters 15 are fixedly installed on opposite sides of the interior surface of the annealing furnace body 1. An infrared microwave heater 16 is fixedly installed on the upper surface of the interior of the annealing furnace body 1. A controller 17 is fixedly installed on the top surface of the annealing furnace body 1. By setting the resistance wire heaters 15 and the infrared microwave heaters 16, the annealing temperature can be precisely controlled, which improves the annealing efficiency, helps to reduce energy consumption, and achieves energy conservation and emission reduction.

[0027] It should be noted that in this embodiment, the controller 17 is connected and controlled to the resistance wire heater 15 and the infrared microwave heater 16 via connecting wires.

[0028] The working principle of the above embodiments is as follows:

[0029] When the insulation cover 2 is fitted onto the annealing furnace body 1, the L-shaped connecting plate 8 is moved along one end of the open structure of the U-shaped groove 3, so that the guide rail 12 engages with the pulley 14, allowing the insulation cover 2 to slide on the U-shaped groove 3, aligning the strip groove 9 with the fixing groove 10 and the fixing pin 7. By pulling the pull rod 11, the elastic force of the top spring 5 can be overcome, causing the fixing pin 7 to retract and move into the hollow cylinder 4 until the L-shaped connecting plate 8 contacts the closed end of the U-shaped groove 3. At this time, the fixing pin 7 and the fixing groove 10 correspond. Release the pull rod 11, and push the connecting block 6 and the fixing pin 7 through the top spring 5, so that the fixing pin 7 is engaged in the fixing groove 10, thus realizing the connection between the insulation cover 2 and the annealing furnace body 1. The heating power and temperature of the resistance wire heater 15 and the infrared microwave heater 16 are precisely adjusted by the controller 17 to meet the needs of different annealing processes.
