Description
Technical Field
[0001] This utility model relates to the field of workpiece heat treatment, specifically an adjustable heat treatment furnace temperature guiding device. Background Technology
[0002] A heat treatment furnace refers to an electric or fuel-fired furnace used for heating furnace materials for heat treatment. Commonly used heat treatment furnaces include box-type resistance furnaces, pit-type resistance furnaces, gas carburizing furnaces, and salt bath furnaces. Continuous furnaces are typically used, where workpieces are continuously loaded through the feeding door, pass through the furnace chamber, and are continuously discharged through the discharge door. The commonly used method of conveying workpieces within the furnace is to place them on heat-resistant steel guide rails and move them using a walking beam or push rod. In recent years, heat-resistant steel conveyor belts have been increasingly adopted for material transport. This makes the heat treatment operation more rational and greatly increases the possibility of automation and unmanned management of the heat treatment process.
[0003] However, most traditional heat treatment furnaces (such as box furnaces and pit furnaces) have a fixed furnace structure. Workpieces need to be hoisted or manually moved to a designated position inside the furnace. Due to the limited furnace space and lack of internal moving devices, it is difficult to adjust the position of the workpiece once it is placed. When uniform heating or specific processes (such as graded quenching) are required, the fixed position of the workpiece may lead to uneven heating, affecting the heat treatment quality. Furthermore, the operation of traditional heat treatment furnaces relies heavily on manual labor, which is not only inefficient but also makes it difficult to adjust the position of the workpiece in real time. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, most traditional heat treatment furnaces have a fixed furnace structure. Workpieces need to be hoisted or manually transported to a designated position inside the furnace. Due to the limited furnace space and lack of internal moving devices, it is difficult to adjust the position of the workpiece once it is placed. When uniform heating or specific processes (such as graded quenching) are required, the fixed position of the workpiece may lead to uneven heating and affect the heat treatment quality. This utility model proposes an adjustable heat treatment furnace temperature guiding device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable heat treatment furnace temperature guiding device, including a furnace body, a sealing door rotatably connected to one side of the furnace body, an observation window opened on one side of the sealing door, and an adjustment mechanism and a guiding mechanism provided in the inner cavity of the furnace body; The adjustment mechanism includes four driven shafts, one end of each driven shaft is rotatably connected to the inner cavity of the furnace body, one end of each driven shaft is fixedly connected to a placement plate, and a driven gear is fixedly connected to the surface of each driven shaft.
[0006] Preferably, the inner cavity of the furnace body is rotatably connected to a drive shaft, and a drive gear is fixedly connected to the surface of the drive shaft, with the teeth of the drive gear and the teeth of the driven gear meshing with each other.
[0007] Preferably, the inner wall of the furnace body is fixedly connected to a heat insulation cover, and both the driving gear and the driven gear are disposed in the inner cavity of the heat insulation cover.
[0008] Preferably, the flow guiding mechanism includes a housing, one side of which is fixedly connected to the inner wall of the furnace body, an impeller is rotatably connected to the inner cavity of the housing, and one end of the drive shaft is fixedly connected to the inner wall of the impeller.
[0009] Preferably, a fixing frame is fixedly connected to the top of the furnace body, and a motor is fixedly installed in the inner cavity of the fixing frame. The output end of the motor passes through the furnace body and the outer shell and is fixedly connected to one side of the impeller.
[0010] Preferably, an air inlet is provided on one side of the outer casing, and an air guide shroud is fixedly connected to one side of the outer casing, with the inner wall of the air guide shroud and the inner wall of the air inlet communicating with each other.
[0011] Preferably, the surface of the outer shell is fixedly connected to an air supply pipe, and there are four air supply pipes. The four air supply pipes are all L-shaped and one end is fixedly connected to the inner wall of the furnace body. One side of each air supply pipe is fixedly connected to a blower pipe, and there are multiple blower pipes.
[0012] The advantages of this utility model are: In this utility model, the placement plate in the adjusting mechanism is rotatably connected to the furnace cavity via a driven shaft. After the workpiece is placed on the placement plate, it rotates within the furnace cavity, thus constantly adjusting the workpiece's position to ensure uniform heating. The motor can be considered the driving source in the flow guiding mechanism. The motor drives the impeller to rotate along the inner cavity of the outer shell. Simultaneously, the impeller's rotation drives the drive shaft on the inner wall to rotate. When the drive shaft rotates, it drives the coaxial drive gear to rotate. Because the teeth of the drive gear and the driven gear mesh, the rotation of the drive gear drives the driven gear to rotate. The driven gear and the driven shaft... The components are coaxially fixedly connected, so the driven gear can rotate while the driven shaft rotates, thereby realizing the automatic rotation adjustment of the placement tray. This minimizes the possibility of the workpiece being heated on one side during heat treatment, which can lead to uneven heating. This solves the problem that most traditional heat treatment furnaces have a fixed furnace structure, requiring workpieces to be hoisted or manually moved to a designated position inside the furnace. Due to the limited furnace space and lack of internal moving devices, it is difficult to adjust the position of the workpiece once it is placed. When uniform heating or specific processes (such as graded quenching) are required, the fixed position of the workpiece may lead to uneven heating and affect the quality of heat treatment.

[0016] 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 scope of protection of the present utility model.
[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an adjustable heat treatment furnace temperature guiding device. (Refer to...) Figures 1 to 3 An adjustable heat treatment furnace temperature guiding device includes a furnace body 1, a sealing door 2 rotatably connected to one side of the furnace body 1, an observation window 3 opened on one side of the sealing door 2, and an adjustment mechanism 4 and a guiding mechanism 5 provided in the inner cavity of the furnace body 1. The regulating mechanism 4 includes four driven shafts 401, one end of each driven shaft 401 is rotatably connected to the inner cavity of the furnace body 1. A placement plate 402 is fixedly connected to one end of each driven shaft 401. A driven gear 403 is fixedly connected to the surface of each driven shaft 401. A drive shaft 404 is rotatably connected to the inner cavity of the furnace body 1. A drive gear 405 is fixedly connected to the surface of the drive shaft 404. The teeth of the drive gear 405 and the teeth of the driven gear 403 mesh with each other. The flow guiding mechanism 5 includes a housing 501. One side of the housing 501 is fixedly connected to the inner wall of the furnace body 1. An impeller 502 is rotatably connected to the inner cavity of the housing 501. One end of the drive shaft 404 is fixedly connected to the inner wall of the impeller 502. A fixing frame 6 is fixedly connected to the top of the furnace body 1. A motor 7 is fixedly installed in the inner cavity of the fixing frame 6. The output end of the motor 7 passes through the furnace body 1 and the housing 501 and is fixedly connected to one side of the impeller 502. In this adjustable heat treatment furnace temperature guiding device, the furnace body 1 plays a major supporting and sealing role. The sealing door 2 can seal the port of the furnace body 1, further improving the heat preservation effect of the furnace body 1. The heat treatment status of the workpiece inside can be observed through the observation window 3. The placement plate 402 in the adjustment mechanism 4 is rotatably connected to the inner cavity of the furnace body 1 through the driven shaft 401. After the workpiece is placed on the placement plate 402, it can drive the workpiece to rotate in the inner cavity of the furnace body 1, thereby constantly rotating and adjusting the position of the workpiece to ensure uniform heating of the workpiece. The motor 7 can be regarded as the driving source in the guiding mechanism 5. The motor 7 can drive the impeller 502 to move along the inner cavity of the outer shell 501. The impeller 502 rotates, which in turn drives the drive shaft 404 on the inner wall to rotate. When the drive shaft 404 rotates, it drives the coaxial drive gear 405 to rotate. Since the teeth of the drive gear 405 and the driven gear 403 mesh, the rotation of the drive gear 405 drives the driven gear 403 to rotate. The driven gear 403 and the driven shaft 401 are coaxially fixedly connected. Therefore, the rotation of the driven gear 403 drives the driven shaft 401 to rotate at the same time, thereby realizing the automatic rotation adjustment of the placement plate 402 and minimizing the uneven heating caused by one side of the workpiece being heated during the heat treatment process.
[0018] Reference Figure 2 A heat insulation cover 406 is fixedly connected to the inner wall of the furnace body 1. The driving gear 405 and the driven gear 403 are both set in the inner cavity of the heat insulation cover 406. The heat insulation cover 406 can be made of metal materials such as tungsten or titanium alloy to seal and insulate the driving gear 405 and the driven gear 403 in the inner cavity, thereby improving the service life of the driving gear 405 and the driven gear 403.
[0019] Reference Figure 3 and Figure 4An air inlet 503 is provided on one side of the outer shell 501, and an air guide hood 504 is fixedly connected to one side of the outer shell 501. The inner wall of the air guide hood 504 is connected to the inner wall of the air inlet 503. Through the air inlet 503, the impeller 502 generates negative pressure in the air inlet 503 during rotation, thus drawing hot air from the furnace body 1 into the inner cavity of the outer shell 501. The air guide hood 504 can improve the efficiency of hot air entering the inner cavity of the outer shell 501.
[0020] Reference Figure 2 and Figure 4 The surface of the outer shell 501 is fixedly connected to an air supply pipe 505. There are four air supply pipes 505, each L-shaped and with one end fixedly connected to the inner wall of the furnace body 1. Each air supply pipe 505 is fixedly connected to a blower pipe 506 on one side. There are multiple blower pipes 506. The four sets of air supply pipes 505 correspond to a set of placement trays 402. The impeller 502 guides hot air into the inner cavity of the outer shell 501 and delivers the hot air evenly to each air supply pipe 505. Since the blower pipe 506 and the air supply pipe 505 are connected, the hot air is sprayed from the port of the blower pipe 506 onto the corresponding workpiece surface after passing through the air supply pipe 505, so that the workpiece is subjected to uniform heat treatment.
[0021] Working principle: Opening the sealing door 2 allows workpieces to be placed on the placement tray 402. Closing the sealing door 2 seals the port of the furnace body 1, further improving the heat preservation effect of the furnace body 1. The heat treatment status of the internal workpieces can be observed through the observation window 3. The motor 7 can be regarded as the driving source in the flow guiding mechanism 5. The motor 7 drives the impeller 502 to rotate along the inner cavity of the outer shell 501. While the impeller 502 rotates, it drives the drive shaft 404 on the inner wall to rotate. When the drive shaft 404 rotates, it drives the coaxial drive gear 405 to rotate. Since the teeth of the drive gear 405 and the driven gear 403 mesh, the rotation of the drive gear 405 drives the driven gear 403 to rotate. The driven gear 403 and the driven shaft 401 are coaxially fixedly connected, so the rotation of the driven gear 403... Simultaneously, it can drive the driven shaft 401 to rotate, thereby realizing the automatic rotation adjustment of the placement tray 402. While the impeller 502 rotates, it generates negative pressure at the air inlet 503, thus drawing hot air from the furnace body 1 into the inner cavity of the outer shell 501. The set air guide hood 504 can improve the efficiency of hot air entering the inner cavity of the outer shell 501. The four sets of air supply pipes 505 are respectively corresponding to one set of placement trays 402. The impeller 502 guides the hot air into the inner cavity of the outer shell 501 and simultaneously delivers the hot air evenly to each air supply pipe 505. Since the blowing pipe 506 and the air supply pipe 505 are connected, the hot air is sprayed from the port of the blowing pipe 506 onto the corresponding workpiece surface after passing through the air supply pipe 505, so that the workpiece is subjected to uniform heat treatment and the workpiece is heated on one side during the heat treatment process as much as possible, which would lead to uneven heating.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
