Description

Technical Field

[0001] This utility model relates to the field of copper rod production and processing technology, and in particular to a copper rod heat treatment homogenization furnace. Background Technology

[0002] Copper rods are long, strip-shaped materials made primarily of copper, widely used in power generation, machinery manufacturing, and architectural decoration. During their processing, the heat treatment homogenization furnace plays a significant role. It improves the microstructure of the copper rod, ensuring uniform grain growth and stress relief; it enhances performance stability, precisely controls temperature to avoid performance variations; and it guarantees consistent product quality, reducing batch-to-batch quality fluctuations and ensuring the high-quality requirements of various industries for copper rods.

[0003] Traditional copper rod heat treatment typically uses products such as trolley-type resistance furnaces to perform isothermal equalization operations on copper rods. However, traditional isothermal furnaces only heat the furnace interior using a single heating wire. Over time, due to the large internal space, the furnace body cools down rapidly. Furthermore, during isothermal equalization, the heat energy inside the furnace cannot be distributed to the center of the furnace, leading to faster cooling of the copper rod in the center of the furnace. Therefore, a copper rod heat treatment isothermal equalization furnace is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a copper rod heat treatment uniform temperature furnace, which aims to improve the problem that the existing technology cannot achieve efficient and uniform heat energy filling the entire furnace chamber, thus causing the furnace body to lose temperature quickly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a uniform temperature furnace for heat treatment of copper rods, comprising a furnace body, wherein a flow-dividing cavity is provided inside the furnace body, and a symmetrical constant temperature plate is fixedly connected to one side of the inner wall of the furnace body. Multiple through holes are provided inside the furnace body and the constant temperature plate. A constant temperature component is installed on the upper surface of the furnace body, and a slide rail is fixedly connected to one side of the outer wall of the furnace body. A moving wheel is provided on the upper surface of the slide rail, and a moving cart is provided on the upper side of the moving wheel. A heat insulation plate is fixedly connected to one side of the outer wall of the moving cart.

[0006] The constant temperature component includes a transfer hopper, the lower surface of which is fixedly connected to the upper surface of the furnace body. A heating wire is fixedly connected inside the transfer hopper, and a protective box is fixedly connected to one side of the outer wall of the transfer hopper. The transfer component is installed inside the protective box.

[0007] Furthermore, the transmission component includes a fan, the outer wall of which is fixedly connected to the inside of the protective box, and the outer wall of the fan is covered with a filter cover.

[0008] Furthermore, a rotating shaft is rotatably connected inside the insulation board, a handwheel is fixedly connected to one end of the rotating shaft, a winding assembly is installed at one end of the rotating shaft, and a clamping assembly is installed on the upper surface of the insulation board.

[0009] Furthermore, the winding assembly includes a turntable with a limiting groove inside. A fixing rod is fixedly connected to one side of the outer wall of the turntable, and a bidirectional lead screw is rotatably connected inside the fixing rod. An arc-shaped plate is threadedly connected to the outer wall of the bidirectional lead screw.

[0010] Furthermore, the clamping assembly includes a telescopic rod, one end of which is fixedly connected to the surface of the insulation board, a spring is sleeved on the outer wall of the telescopic rod, and an abutment wheel is installed at one end of the telescopic rod.

[0011] Furthermore, the transmission bucket is connected to the diversion cavity, and the transmission bucket is used to transmit thermal energy.

[0012] Furthermore, the outer wall of the bidirectional lead screw is slidably connected to the inner wall of the limiting groove, and the limiting groove is used to limit the movement of the bidirectional lead screw.

[0013] Furthermore, one end of the spring is fixedly connected to the surface of the insulation board, and the other end of the spring is installed on one side of the contact wheel.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, external air is filtered through a filter cover by a fan and then transmitted to the inside of the transmission hopper. The airflow is then transmitted to the vicinity of the heating wire by the transmission hopper. The heating wire heats the airflow, which is then transmitted to the inside of the distribution cavity. Simultaneously, it is evenly transmitted to the inside of the furnace body through the through holes, thereby achieving the effect of efficiently distributing hot air into the furnace body. At the same time, the constant temperature plate can slow down the temperature drop time inside the furnace body, thus improving the practicality of the equipment.

[0016] 2. In this utility model, by winding the copper rod around the outside of the arc-shaped plate, the handwheel is turned to make the rotating shaft drive the turntable to rotate, thereby achieving the effect of placing the copper rod to prevent it from falling due to the influence of the external environment. Then, by rotating the double-acting screw, the arc-shaped plate supports the inner diameter of the copper rod coil. At the same time, the reaction force of the spring pushes the contact wheel to abut against the outside of the copper rod coil, thereby achieving the effect of efficiently fixing the copper rod coil and improving the practicality of the equipment.

[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] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a copper rod heat treatment uniform temperature furnace, including a furnace body 1, a flow distribution cavity 2 is opened inside the furnace body 1, a symmetrical constant temperature plate 4 is fixedly connected to one side of the inner wall of the furnace body 1, a plurality of through holes 3 are opened inside the furnace body 1 and the constant temperature plate 4, a constant temperature component is installed on the upper surface of the furnace body 1, a slide rail 10 is fixedly connected to one side of the outer wall of the furnace body 1, a moving wheel 13 is provided on the upper surface of the slide rail 10, a moving cart 11 is provided on the upper side of the moving wheel 13, and a heat insulation plate 12 is fixedly connected to one side of the outer wall of the moving cart 11;

[0025] The constant temperature component includes a transfer hopper 5, the lower surface of which is fixedly connected to the upper surface of the furnace body 1. A heating wire 6 is fixedly connected inside the transfer hopper 5. A protective box 7 is fixedly connected to one side of the outer wall of the transfer hopper 5. The transfer component is installed inside the protective box 7. The transfer component includes a fan 8, the outer wall of which is fixedly connected to the inside of the protective box 7. A filter cover 9 is provided on the outer wall of the fan 8.

[0026] Specifically, the furnace body 1 is the main structure. Its internal distribution cavity 2 ensures even heat distribution, preventing localized overheating or undercooling. Symmetrical constant-temperature plates 4 on both sides of the inner wall further stabilize the furnace temperature. Multiple through-holes 3 on the furnace body 1 and constant-temperature plates 4 facilitate heat and airflow, ensuring temperature uniformity. The constant-temperature components on the upper surface of the furnace body 1 provide and regulate the furnace temperature. The transfer hopper 5 serves as a heat transfer channel, and the internal heating wire 6 is the heat source, generating heat after being energized to provide the necessary thermal energy for the copper rod heat treatment within the furnace. The protective box 7 protects the internal transfer components and reduces heat loss. The fan 8 within the transfer components promotes the circulation of hot air within the furnace body 1, ensuring the heat... The heat is more evenly distributed to all parts of the copper rod. The filter cover 9 on the outer wall of the blower 8 can filter impurities in the air, preventing impurities from entering the blower 8 and affecting its operation. It also prevents impurities from circulating in the furnace and affecting the quality of the copper rod. The slide rail 10 on the outer wall of the furnace body 1 provides guidance for the movement of the moving cart 11. The moving wheels 13 under the moving cart 11 can move smoothly on the slide rail 10, making it convenient to send the copper rod into or out of the furnace body 1. The heat insulation plate 12 on the outer wall of the moving cart 11 can reduce the heat loss of the copper rod during transportation, ensuring that the temperature change of the copper rod is small before entering the furnace body 1 or after being taken out. This helps to improve the stability and consistency of the heat treatment effect, enabling the entire uniform temperature furnace system to perform heat treatment operations on the copper rod efficiently and accurately.

[0027] Reference Figure 1 - Figure 4 The insulation board 12 has a rotating shaft 15 internally connected to it. A handwheel 16 is fixedly connected to one end of the rotating shaft 15, and a winding assembly is installed at one end of the rotating shaft 15. A clamping assembly is installed on the upper surface of the insulation board 12. The winding assembly includes a turntable 14, which has a limit groove 18 inside. A fixing rod 17 is fixedly connected to one side of the outer wall of the turntable 14. A double-acting screw 19 is rotatably connected inside the fixing rod 17, and an arc-shaped plate 20 is threaded onto the outer wall of the double-acting screw 19. The clamping assembly includes a telescopic rod 21. One end of the telescopic rod 21 is fixedly connected to the upper surface of the insulation board 12. A spring 22 is sleeved on the outer wall of the telescopic rod 21. An abutment wheel 23 is installed at one end of the telescopic rod 21. The transmission bucket 5 is connected to the diversion cavity 2 and is used to transmit heat energy. The outer wall of the bidirectional screw 19 is slidably connected to the inner wall of the limiting groove 18. The limiting groove 18 is used to limit the movement of the bidirectional screw 19. One end of the spring 22 is fixedly connected to the upper surface of the insulation board 12, and the other end of the spring 22 is installed on one side of the abutment wheel 23.

[0028] Specifically, the rotating shaft 15 inside the insulation board 12 can drive the winding assembly to work when it rotates. The handwheel 16 at one end allows the operator to manually apply force to rotate the rotating shaft 15. The limiting groove 18 inside the turntable 14 in the winding assembly guides and restricts the movement of the bidirectional lead screw 19, ensuring that it can only move in a specific direction. The fixing rod 17 on the outer wall provides support for the bidirectional lead screw 19. When the bidirectional lead screw 19 rotates, the arc-shaped plate 20 threaded to its outer wall can move relative to it, thereby realizing the clamping or releasing action of the copper rod. This facilitates fixing the position of the copper rod during the transportation of the copper rod by the moving cart 11 and prevents the copper rod from slipping. If the copper rod falls or shifts, the clamping assembly on the upper surface of the insulation plate 12 is used to assist in fixing the copper rod. The telescopic rod 21 can extend and retract within a certain range. The spring 22 on its outer wall provides elastic pressure to the contact wheel 23, so that the contact wheel 23 can fit tightly against the surface of the copper rod, further enhancing the clamping stability of the copper rod. During transportation, even if it encounters bumps or shaking, it can effectively maintain the position stability of the copper rod. In conjunction with the winding assembly, it comprehensively ensures the safety and stability of the copper rod during the movement process, ensuring that the copper rod can smoothly enter and exit the furnace body 1 for heat treatment operations, and ensuring the continuity and reliability of the entire heat treatment uniform temperature furnace process.

[0029] Working principle: When using this uniform temperature furnace to heat treat copper rods, the copper rods are first wound around the outside of the arc plate 20. Then, by turning the handwheel 16, the rotating shaft 15 drives the turntable 14 to rotate. The rotation of the turntable 14 achieves the effect of placing the copper rods. At the same time, by turning the double-acting screw 19, the arc plate 20 is supported outward, thereby supporting the inner diameter of the copper rod coil. Then, by the reaction force of the spring 22, the extension and contraction of the spring 22 achieves the effect of adjusting and fixing the copper rod coil according to the outer diameter of the copper rod coil.

[0030] Secondly, by pushing the moving cart 11, the moving wheels 13 move on the upper surface of the slide rail 10, thereby locking the moving cart 11 onto one side of the furnace body 1 to achieve a sealing effect. At this time, the heating wire 6 and the fan 8 are started. The fan 8 then filters the external airflow through the filter cover 9 and transmits it into the transmission hopper 5. The heating wire 6 then heats the airflow and transmits it to one side of the through hole 3 through the diversion cavity 2. The diversion through the through hole 3 achieves the effect of evenly distributing heat energy into the furnace body 1. With the cooperation of the constant temperature plate 4, the rate at which the temperature inside the furnace body 1 decreases is slowed down.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
