Description

Technical Field

[0001] This utility model relates to the technical field of box furnace equipment, specifically a box furnace. Background Technology

[0002] Box furnaces, as the core equipment for heat treatment of metal materials, are widely used in processes such as quenching, annealing, and tempering. Their core function is to optimize the microstructure of metal materials by precisely controlling the temperature field distribution inside the furnace. Box furnaces use electric heating elements such as resistance wires made of nickel-chromium alloy, iron-chromium-aluminum alloy, silicon carbide rods, or silicon molybdenum rods to generate heat, converting electrical energy into heat energy, which heats the air inside the furnace to form a hot airflow.

[0003] Existing box furnaces mostly use fixed placement racks, requiring operators to manually reach into the furnace to retrieve and place metal materials, which is easy to cause burns from high-temperature radiation. In addition, the placement racks are mostly solid plate structures, which hinder the full contact between hot air and objects. Furthermore, in terms of controlling the distribution of hot air inside the furnace, existing box furnaces mainly generate heat through heating elements on the side walls or bottom of the furnace body, and then rely on the natural convection of hot air to achieve temperature diffusion inside the furnace. They cannot dynamically adjust the direction of hot air according to the size of the materials or process requirements, which easily leads to uneven heat distribution. Therefore, this utility model provides a box furnace. Utility Model Content

In addition, the placement racks are mostly solid plate structures, which hinder the full contact between hot air and objects. Furthermore, in terms of the control of hot air distribution in the furnace, existing box furnaces mainly generate heat through heating elements on the side walls or bottom of the furnace body, and then rely on the natural convection of hot air to achieve the temperature diffusion in the furnace. They cannot dynamically adjust the direction of hot air according to the size of the material or process requirements, which easily causes uneven heat distribution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a box furnace, comprising a box furnace body, a front cabinet door at the front end of the box furnace body, and an installation mechanism for heat treatment of metal materials on the box furnace body, the installation mechanism comprising: The material handling assembly includes a slide rail bracket fixed to the inner wall of the box furnace body, and a placement rack connected to the slide rail bracket via a drive assembly is slidably arranged inside the slide rail bracket; The dispersion component includes a fan blade body located at the top of the interior of the box furnace body.

[0010] Preferably, one end of the second screw is provided with a drive shaft, and one end of the drive shaft is provided with a drive body.

[0011] Beneficial effects This utility model provides a box-type furnace. Compared with the prior art, it has the following advantages: Firstly, the first screw of this utility model is threadedly connected to the support slider, and the support slider slides on the inner wall of the support slide rail. The rotation of the first screw will drive the support slider to move along the support slide rail. Since the support slider is fixedly connected to the support plate, the support plate slides in the slide rail bracket, and the placement rack is located on the upper surface of the support plate, the movement of the support slider will drive the support plate and the placement rack to move together, moving the placement rack out of the box furnace body, making it convenient to take out the metal material on the placement rack. When putting in the metal material, the above process can be reversed. The operator does not need to put his hands into the box furnace body, which reduces the difficulty and danger of operation and improves the convenience of picking up and putting in materials. The frame structure of the placement rack increases the contact area between the object and the hot air, avoiding the problem of heat not being able to contact the object due to the placement rack blocking the contact.

[0012] Secondly, the rotation of the second screw in this invention causes the adjusting block to move along the guide rod. The movement of the adjusting block drives the gear rod to move. Because the transmission gear is meshed with the gear rod, the movement of the gear rod drives the transmission gear to rotate, which in turn drives the support shaft to rotate. The rotation of the support shaft changes the angle of the air guide plate. At the same time, the fan blade body rotates, causing the hot air inside the box furnace body to flow. The change in the angle of the air guide plate can adjust the flow direction of the hot air, making the hot air more evenly distributed inside the box furnace body. This changes the flow direction of the hot air inside the box furnace body, making the hot air more evenly distributed inside the box furnace body, thereby making the metal material more evenly heated, improving the heat treatment effect and quality, realizing flexible control of the hot air flow direction, and enhancing the applicability and flexibility of the equipment.

[0015] 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.

[0016] Please see Figures 1-5This utility model provides a technical solution: a box furnace, including a box furnace body 1, a front cabinet door 2 at the front end of the box furnace body 1, and an installation mechanism for heat treatment of metal materials on the box furnace body 1, the installation mechanism including: The material handling assembly includes a slide rail bracket 4 fixed to the inner wall of the box furnace body 1, and a placement rack 402 connected by a drive assembly is slidably arranged inside the slide rail bracket 4. The dispersion component includes a fan blade body 5 located at the top of the inner part of the box furnace body 1. A pair of supporting shells 6 are fixed at the top of the inner part of the box furnace body 1, and the supporting shells 6 are located on both sides of the fan blade body 5. A supporting shaft 601 is evenly rotatably connected through the inner part of the supporting shell 6, and an air guide plate 602 is fixed on the outer wall of the supporting shaft 601.

[0017] In a preferred embodiment, the drive assembly includes a support slide rail 3 fixed to the bottom of the inner side of the box furnace body 1. A first screw 301 is rotatably connected inside the support slide rail 3, and a support slider 302 is slidably connected to the inner wall of the support slide rail 3. The first screw 301 and the support slider 302 are threadedly connected. A support plate 401 is slidably connected inside the slide rail bracket 4. A placement rack 402 is located on the upper surface of the support plate 401. The support slider 302 is fixedly connected to the support plate 401, and the frame structure of the placement rack 402 is used to increase the flow and contact between the object and the hot air.

[0018] Specifically, when it is necessary to remove the metal material placed on the placement rack 402, the first screw 301 is driven to rotate by a motor. The motor is installed on the rear side wall of the furnace body. Since the first screw 301 is threadedly connected to the support slider 302 and the support slider 302 slides on the inner wall of the support slide rail 3, the rotation of the first screw 301 will drive the support slider 302 to move along the support slide rail 3. Since the support slider 302 is fixedly connected to the support plate 401 and the support plate 401 slides in the slide rail bracket 4, and the placement rack 402 is located on the upper end face of the support plate 401, the movement of the support slider 302 will drive the support plate 401 and the placement rack 402 to move together, moving the placement rack 402 out of the box furnace body 1, making it convenient to remove the metal material on the placement rack 402. When putting in the metal material, the above process is reversed.

[0019] In a preferred embodiment, a protective ring 501 is provided on the outer side of the fan blade body 5. The protective ring 501 is fixedly connected to the box furnace body 1 for internal heat circulation. During the rotation of the fan blade body 5, the protective ring 501 is fixed on the box furnace body 1 and always surrounds the outer side of the fan blade body 5, thus playing a protective role.

[0020] In a preferred embodiment, a fixing block 701 is fixed inside the supporting shell 6. A second screw 702 is rotatably connected inside the fixing block 701. An adjusting block 704 is threadedly connected to the outer wall of the second screw 702. A guide rod 703 is fixed to one side of the fixing block 701. The adjusting block 704 is slidably connected to the guide rod 703. A gear rod 705 is fixed to the upper end of the adjusting block 704. A transmission gear 7 is fixed to one end of the supporting shaft 601 near the gear rod 705. The transmission gear 7 is meshed with the gear rod 705. A transmission shaft 8 is provided at one end of the second screw 702. A drive body 801 is provided at one end of the transmission shaft 8. The drive body 801 is installed on the outer wall of the box furnace body 1 and drives multiple air guide plates 602 to adjust. The drive body is activated. 801, the second screw 702 is driven to rotate by the transmission shaft 8. Since the second screw 702 is threadedly connected to the adjusting block 704 and the adjusting block 704 slides on the guide rod 703, the rotation of the second screw 702 will cause the adjusting block 704 to move along the guide rod 703. The movement of the adjusting block 704 will drive the gear rod 705 to move. Since the transmission gear 7 is meshed with the gear rod 705, the movement of the gear rod 705 will drive the transmission gear 7 to rotate, which in turn will drive the support shaft 601 to rotate. The rotation of the support shaft 601 will change the angle of the air guide plate 602. At the same time, the fan blade body 5 will rotate, causing the hot air inside the box furnace body 1 to flow. The change in the angle of the air guide plate 602 can adjust the flow direction of the hot air, so that the hot air is more evenly distributed inside the box furnace body 1.

[0021] The motor mentioned above can be model YKK500-4.

[0022] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0023] During operation, when it is necessary to remove the metal material placed on the placement rack 402, the first screw 301 is driven to rotate by the motor installed on the rear side wall of the furnace body. Since the first screw 301 is threadedly connected to the support slider 302 and the support slider 302 slides on the inner wall of the support slide rail 3, the rotation of the first screw 301 will drive the support slider 302 to move along the support slide rail 3. Since the support slider 302 is fixedly connected to the support plate 401, the support plate 401 slides in the slide rail bracket 4, and the placement rack 402 is located on the upper end face of the support plate 401, the movement of the support slider 302 will drive the support plate 401 and the placement rack 402 to move together, removing the placement rack 402 from the inside of the box furnace body 1, making it convenient to remove the metal material on the placement rack 402. When putting in the metal material, the above process is reversed.

[0024] Then, a protective ring 501 is provided on the outer side of the fan blade body 5. The protective ring 501 is fixedly connected to the box furnace body 1. During the rotation of the fan blade body 5, it always surrounds the outer side of the fan blade body 5, playing a protective role and guiding the internal heat flow. At the same time, the drive body 801 installed on the outer wall of the box furnace body 1 is started, which drives the second screw 702 to rotate through the transmission shaft 8. Since the second screw 702 is threadedly connected to the adjusting block 704 and the adjusting block 704 slides on the guide rod 703, the rotation of the second screw 702 will cause the adjusting block 704 to rotate. 704 moves along guide rod 703, and the movement of adjusting block 704 drives gear rod 705 to move. Because transmission gear 7 is meshed with gear rod 705, the movement of gear rod 705 will drive transmission gear 7 to rotate, which in turn drives support shaft 601 to rotate. The rotation of support shaft 601 changes the angle of air guide plate 602. The rotation of fan blade body 5 causes hot air to flow inside box furnace body 1. The change of angle of air guide plate 602 can adjust the flow direction of hot air, so that hot air is more evenly distributed inside box furnace body 1.
