Description

Technical Field

[0001] This utility model relates to the field of metal wire annealing technology, and in particular to a precision annealing furnace for tin-plated metal wire. Background Technology

[0002] Tin-plated metal wire is an indispensable basic material in electronics, electrical engineering, and communications, and its performance directly affects the conductivity, weldability, and corrosion resistance of products. Annealing, as a key process in the production of tin-plated metal wire, can effectively improve the flexibility, ductility, and conductivity of the wire. With the rapid development of industrial technology, the application scenarios of tin-plated metal wire are becoming increasingly diversified, placing higher demands on the precision, efficiency, and adaptability of the annealing process. Traditional annealing furnaces have certain limitations in terms of wire guiding, positioning, and annealing uniformity, making it difficult to meet the needs of modern industrial production for efficient, precise, and multifunctional annealing treatment.

[0003] Existing metal wire annealing furnaces typically employ fixed guide wheels and heating devices. The metal wire enters the heating zone via the guide wheels for annealing. Heating methods are mostly resistance heating or gas heating, with annealing achieved by controlling the heating temperature and time. Cooling relies on natural cooling or a simple air-cooling system. While this structure meets basic annealing requirements, it has shortcomings in guiding, positioning, and cooling uniformity of the metal wire, especially when processing wires of different diameters or multiple types, lacking flexibility and adaptability. Furthermore, a significant problem exists in existing technologies: the metal wire is prone to deviation during annealing, and cannot be flexibly adjusted according to the wire's thickness and arrangement. Because the guide wheels and heating devices are fixed in position, they cannot adapt to the processing requirements of metal wires of different diameters, leading to uneven annealing results, and even wire deviation or tangling. This not only reduces annealing efficiency but may also affect product quality, limiting the furnace's applicability and practicality. Therefore, a precision annealing furnace for tin-plated metal wire is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a precision annealing furnace for tin-plated metal wire, which aims to improve the problem that the metal wire is prone to deviation during the annealing process and cannot be flexibly adjusted according to the thickness and arrangement requirements of the metal wire in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision annealing furnace for tin-plated metal wire, comprising a base plate, a furnace chamber 1 fixedly connected to one side of the upper surface of the base plate, a hydraulic cylinder 1 fixedly connected to the upper surface of the furnace chamber 1, a heating mechanism 1 fixedly connected to the output end of the hydraulic cylinder 1, a heating mechanism 2 corresponding to the heating mechanism 1 installed on the inner wall of the furnace chamber 1, and multiple guide components installed on the upper surface of the base plate;

[0006] Multiple guide components include a bracket, a limiting sleeve, a threaded sleeve, a guide wheel one, and a guide wheel two. The lower surface of the bracket is fixedly connected to the upper surface of the base plate. The outer wall of the limiting sleeve is rotatably connected to the inside of the bracket.

A spring is fixedly connected to the lower surface of the abutment block. A drive component is installed on one side of the bracket.

[0007] Furthermore, the drive assembly includes a motor and a bidirectional lead screw. One side of the motor is mounted on one side of the outer wall of the bracket, and one end of the bidirectional lead screw is fixedly connected to the output end of the motor. A transmission belt is used to drive the multiple bidirectional lead screws together.

[0008] Furthermore, a second furnace chamber is fixedly connected to the other side of the upper surface of the base plate, and a support cover is fixedly connected to the upper surface of the second furnace chamber.

[0009] Furthermore, an inner cover is fixedly connected to the inner wall of the support cover, and multiple fans are installed through the inside of the support cover, with dust covers installed on the outer walls of the multiple fans.

[0010] Furthermore, multiple rotating rods are rotatably connected inside the inner cover, and guide plates are fixedly connected to the outer walls of the multiple rotating rods.

[0011] Furthermore, a connecting plate is rotatably connected between the outer sides of the plurality of guide plates, and a gear is fixedly connected to one side of the outer wall of one of the rotating rods.

[0012] Furthermore, a hydraulic cylinder is fixedly connected to the upper surface of the second furnace chamber, and a rack plate is fixedly connected to the output end of the second hydraulic cylinder, the rack plate being meshed with a gear.

[0013] Furthermore, the first guide wheel and the second guide wheel are slidably connected to the inner wall of the support frame, the threaded sleeve is threadedly connected to the outer wall of the bidirectional lead screw, and a control panel is fixedly connected to one side of the furnace chamber.

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

[0015] 1. In this utility model, by passing the metal wire through multiple guide wheels 1 and 2, the metal wire is guided, making it easier to organize and preventing deviation. Then, by rotating the adjusting screw, the abutment block drives the spring to move the guide wheel 1 closer to the guide wheel 2, thereby achieving the effect of positioning according to the thickness of the metal wire. At the same time, by sliding the threaded sleeve on the outer wall of the limiting sleeve, the distance between the metal wires can be adjusted according to the usage requirements. In addition, by driving the heating mechanism 1 closer to the heating mechanism 2 through the hydraulic cylinder 1, the metal wire is annealed, thereby improving the practicality of the annealing furnace.

[0016] 2. In this utility model, cold air from outside the second furnace chamber is filtered through a dust cover and then transmitted into the inner cover by a fan. The second hydraulic cylinder drives the rack and pinion plate to mesh and rotate. The rotation of the gear drives the guide plate outside the rotating rod to swing back and forth. Cold air enters the second furnace chamber, thereby achieving a more efficient annealing effect and improving the practicality of the annealing furnace. Attached Figure Description

A furnace chamber 2 is fixedly connected to one side of the upper surface of the base plate 1. The furnace chamber 2 is used to heat the metal wire, forming a closed heating space. A hydraulic cylinder 16 is fixedly connected to the upper surface of the furnace chamber 2, which drives the lifting and lowering adjustment of a heating mechanism 17 to facilitate adjustment of the heating distance and heating intensity. The output end of the hydraulic cylinder 16 is fixedly connected to the heating mechanism 17, which is used to perform top heating of the metal wire, improving heating efficiency. A device corresponding to the heating mechanism 17 is installed on the inner wall of the furnace chamber 2. The corresponding heating mechanism 2 18 is used to heat the metal wire from below, forming double-sided heating with heating mechanism 1 17 to improve heating uniformity and annealing effect. Multiple guide components are installed on the upper surface of the base plate 1. These guide components guide the metal wire smoothly into and through the heating area, preventing deviation and vibration, and ensuring processing accuracy. The multiple guide components include a bracket 3, a limiting sleeve 4, a threaded sleeve 8, a guide wheel 1 13, and a guide wheel 2 14. The lower surface of the bracket 3 is fixedly connected to the upper surface of the base plate 1, supporting the guide components. The outer wall of the limiting sleeve 4 is rotatably connected inside the bracket 3, allowing free rotation of the limiting sleeve 4 to facilitate smooth passage of the metal wire and reduce friction. To prevent rubbing and damage, the inner wall of the threaded sleeve 8 is slidably connected to the outer wall of the limiting sleeve 4. The threaded sleeve 8 can adjust the axial position of the limiting sleeve 4, enhancing the adjustment function. A support frame 9 is fixedly connected to the upper surface of the threaded sleeve 8, providing a mounting base for the adjusting screw 10. The adjusting screw 10 is threadedly connected inside the support frame 9. The adjusting screw 10 can be rotated and adjusted to control the up and down position of the abutment block 11, adjusting the guiding force of the metal wire. An abutment block 11 is installed at one end of the adjusting screw 10. The abutment block 11 is used to directly contact the metal wire, limiting the jump of the metal wire and ensuring stable operation. A spring 12 is fixedly connected to the lower surface of the abutment block 11, providing elastic force to ensure that the abutment block 11 can be flexibly adjusted. Pressure is applied to protect the metal wire from damage. A drive assembly is installed on one side of the bracket 3. The drive assembly is used to realize the synchronous adjustment of the limit sleeve 4 and the threaded sleeve 8, which facilitates the adjustment of the guide assembly position according to the wire diameter during production. The drive assembly includes a motor 6 and a bidirectional lead screw 7. One side of the motor 6 is installed on the outer wall of the bracket 3. The motor 6 is the drive source and provides power output. One end of the bidirectional lead screw 7 is fixedly connected to the output end of the motor 6. The motor 6 drives the bidirectional lead screw 7 to rotate, realizing the synchronous adjustment of the limit sleeve 4. A transmission belt 15 is connected between multiple bidirectional lead screws 7. The transmission belt 15 is used to synchronize the adjustment action of multiple guide assemblies, ensure that the multi-point guidance is coordinated and consistent, and avoid uneven guidance that causes the metal wire to deviate.

[0024] Specifically, the above design can effectively ensure that the metal wire is heated evenly and runs smoothly during the annealing process, avoiding deviation, shaking or damage of the metal wire, improving annealing accuracy and processing quality. The double-sided heating structure, combined with the multi-point adjustable guide component, achieves strong adaptability to metal wires of different specifications, meets various production needs, and the synchronous adjustment of the drive component improves adjustment efficiency and accuracy, reduces manual operation intensity, and improves the overall production efficiency and ease of use of the machine.

[0025] Reference Figure 1 , Figure 2 and Figure 3A second furnace chamber 19 is fixedly connected to the other side of the upper surface of the base plate 1. The second furnace chamber 19 is used for subsequent processing of the metal wire to ensure the stability of the metal wire's performance after annealing. A support cover 20 is fixedly connected to the upper surface of the second furnace chamber 19. The support cover 20 is used to protect the internal structure and provide an installation base for subsequent cooling and guiding devices. An inner cover 21 is fixedly connected to the inner wall of the support cover 20. The inner cover 21 is used to isolate the airflow and dust generated by the fan 22, preventing them from directly acting on the surface of the metal wire and protecting the stability of the metal wire's quality. Multiple fans 22 are installed inside the support cover 20. The multiple fans 22 are used to generate forced airflow to cool the metal wire, improve the cooling speed and efficiency, and ensure the uniform and stable performance of the metal wire. The outer wall of the fan 22 is equipped with a dust cover 23, which prevents dust and impurities from entering the fan 22, ensuring stable operation and extending the service life of the fan 22. Multiple rotating rods 24 are rotatably connected inside the inner cover 21. These rods support and drive the guide plates 25 to rotate, ensuring smooth guidance of the metal wire during operation. Guide plates 25 are fixedly connected to the outer walls of the rotating rods 24, guiding and limiting the trajectory of the metal wire to prevent deviation and swaying, thus improving processing accuracy. Connecting plates 5 are rotatably connected between the outer sides of the multiple guide plates 25, connecting them into a single unit to enhance the stability and synchronization of the overall structure, ensuring smooth operation of the multiple guide plates. The guide plates 25 move simultaneously to avoid uneven guidance; a gear 26 is fixedly connected to one side of the outer wall of a rotating rod 24, which meshes with the rack plate 28 to achieve precise rotation control of the rotating rod 24 and improve the adjustment efficiency of the guide plate 25; a hydraulic cylinder 27 is fixedly connected to the upper surface of the furnace chamber 2 19, which drives the rack plate 28 to move up and down, adjusting the working state and force of the guiding device. The output end of the hydraulic cylinder 27 is fixedly connected to the rack plate 28, which meshes with the gear 26. The rack plate 28 drives the gear 26 to rotate through the hydraulic cylinder 27, thereby achieving synchronous adjustment of the guide plate 25 and improving adjustment efficiency and accuracy; guide wheels 1 13 and guide wheels 2 14 are... The guide wheel 13 and guide wheel 14 are slidably connected to the inner wall of the support frame 9 to guide the movement of the metal wire. The sliding connection facilitates the adjustment of the guide wheel position, adapts to metal wires of different specifications, and improves processing applicability. The threaded sleeve 8 is threadedly connected to the outer wall of the bidirectional lead screw 7. The threaded sleeve 8 can be precisely adjusted by rotating the bidirectional lead screw 7, which facilitates the adjustment of the guiding position of the guide assembly and improves the stability and accuracy of the metal wire movement. A control panel 29 is fixedly connected to one side of the furnace chamber 2. The control panel 29 is used to centrally control the operating parameters of the entire set of equipment, including heating temperature, fan speed 22, hydraulic cylinder action, etc., to realize automated operation, facilitate user control of equipment operation status, and improve operational convenience and safety.

[0026] Specifically, the above design, through the combination of a dual furnace chamber, a cooling fan 22, and an adjustable guiding mechanism, can effectively improve the overall efficiency and processing accuracy of the metal wire annealing and cooling process, avoid the metal wire from deviating and being damaged during processing, and ensure stable processing quality. The gear and rack structure design driven by the hydraulic cylinder 27 enables precise synchronous adjustment of the guiding device, adapting to the processing of metal wires with different diameters and performance requirements. Combined with the centralized control panel 29, it improves the automation level and ease of operation of the equipment, enhancing the practicality and production efficiency of the equipment.

[0027] Working principle: When this precision annealing furnace is needed, multiple metal wires are first passed between furnace chamber 1 (2) and furnace chamber 2 (19), and simultaneously between guide wheel 1 (13) and guide wheel 2 (14). Rotating the adjusting screw 10 causes the contact block 11 to contract the spring 12, simultaneously driving guide wheel 1 (13) to adjust the metal wires according to their thickness to the outside of guide wheel 2 (14). Then, the control panel 29 sends an electrical signal to start the motor 6. The motor 6 drives the bidirectional screw 7 to rotate, simultaneously adjusting the distance between multiple threaded sleeves 8 outside the limiting sleeve 4. At this time, the control panel 29 controls the hydraulic cylinder 1 (16) to drive the heating unit. The first structure 17 is located near the second heating mechanism 18, thus enabling the annealing effect by adjusting the distance between the first heating mechanism 17 and the second heating mechanism 18 according to the usage requirements. Then, the fan 22 is started by the control panel 29. The fan 22 transmits the cold air outside the second furnace chamber 19 through the dust cover 23 to the vicinity of the guide plate 25. At this time, the hydraulic cylinder 27 is started by the control panel 29, thus enabling the hydraulic cylinder 27 to drive the rack plate 28 to mesh and rotate with the gear 26. The gear 26 then drives the guide plate 25 outside the rotating rod 24 to swing, thus achieving the effect of efficient cooling of the metal wire.
