Description

Technical Field

[0001] This utility model belongs to the field of material heat treatment equipment control technology, and in particular relates to a temperature uniformity control device for a heat treatment furnace for nickel-based alloy forgings. Background Technology

[0002] According to the published patent CN211451916U, a calcining furnace temperature control device includes a controller, multiple burners, and two sets of temperature detectors. The multiple burners are located in the first calcining chamber of the calcining furnace, and each set of temperature detectors includes multiple temperature sensors. The two sets of temperature detectors are located in the first and second calcining chambers of the calcining furnace, respectively. Both the burners and temperature detectors are electrically connected to the controller. This device facilitates the control of the calcining temperature of the calcining furnace, but it still has the following shortcomings:

[0003] The above equipment achieves the effect of facilitating the control of the roasting temperature in the roasting furnace. However, due to the excessively fast flow rate of high-temperature airflow such as protective gas and circulating hot air in the heat treatment furnace, if the forging is not fixed, it may be displaced due to the impact of the airflow, which may easily lead to changes in the distance between it and the heating element, furnace wall or other forgings, thereby causing local temperature abnormalities. Therefore, we provide a temperature uniformity control device for the heat treatment furnace of nickel-based alloy forgings. Summary of the Invention

[0004] The purpose of this invention is to provide a temperature uniformity control device for a heat treatment furnace of nickel-based alloy forgings. Through the clamping mechanism and the rotating mechanism, the above-mentioned equipment can achieve the effect of easy control of the roasting temperature of the roasting furnace. However, due to the excessively fast flow rate of high-temperature airflow such as protective gas and circulating hot air in the heat treatment furnace, if the forging is not fixed, it may be displaced due to the impact of the airflow, which may easily lead to changes in the distance between it and the heating element, furnace wall or other forgings, thereby causing local temperature abnormalities.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a temperature uniformity control device for a heat treatment furnace of nickel-based alloy forgings, including a heating furnace. Several supports are fixedly connected to the outer wall of the heating furnace, and several heating blocks are fixedly connected to the inner wall of the heating furnace near the supports. A clamping mechanism is provided on the inner wall of the heating furnace.

[0007] The clamping mechanism includes a main board, the outer wall of which is rotatably connected to the inner wall of the heating furnace. An auxiliary barrel is fixedly connected to the outer wall of the main board near the heating block. A threaded rod is rotatably connected to the inner wall of the auxiliary barrel. A worm gear is fixedly connected to the outer wall of the threaded rod near the auxiliary barrel. A threaded barrel is threadedly connected to the outer wall of the threaded rod. Several rotating plates are rotatably connected to the inner wall of the threaded barrel. A rotating frame is rotatably connected to the inner wall of the rotating plates away from the threaded barrel. A fixed rod is rotatably connected to the inner wall of the rotating frame away from the rotating plates.

[0008] Furthermore, a support bar is fixedly connected to the outer wall of the fixing rod, and the outer wall of the support bar is fixedly connected to the outer wall of the main board.

[0009] Furthermore, a clamping block is fixedly connected to the outer wall of the rotating frame on the side away from the rotating plate, and the inner wall of the clamping block is provided with several anti-slip grooves.

[0010] Furthermore, a worm gear is rotatably connected to the inner wall of the main board near the auxiliary barrel, the outer wall of the worm gear meshes with the outer wall of the worm wheel, and a rotating mechanism is provided on the outer wall of the heating furnace.

[0011] Furthermore, the rotating mechanism includes a protective shell, the outer wall of which is fixedly connected to the outer wall of the heating furnace, and a connecting block is fixedly connected to the outer wall of the main board near the protective shell.

[0012] Furthermore, a bevel gear two is fixedly connected to the outer wall of the connecting block at the end away from the heating block, and a motor plate is fixedly connected to the outer wall of the heating furnace at the end away from the heating block.

[0013] Furthermore, a controller is fixedly connected to the outer wall of the motor plate at the end away from the heating block, and a motor is fixedly connected to the outer wall of the motor plate at the end close to the heating block.

[0014] Furthermore, the bottom output shaft of the motor is fixedly connected to a rotating shaft via a coupling, and a bevel gear is fixedly connected to the outer wall of the end of the rotating shaft away from the motor. The outer wall of the bevel gear meshes with the outer wall of a second bevel gear.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates clamping blocks. First, the heating furnace is turned on. Then, one end of the material is placed in contact with the surface of one side of the clamping block. Subsequently, the worm gear is rotated, and the rotating frame drives the clamping block to rotate. The rotation of the clamping blocks on both sides is used to fix the position of the material. Anti-slip grooves are used to prevent the material from falling off during processing, thus achieving stable clamping of the material and preventing the material from falling off the clamping blocks during processing.

[0017] 2. This utility model sets up multiple heating blocks, which are then activated to heat the material. The controller then starts the motor, which drives the main board, auxiliary barrel, and the entire device to rotate via the connecting block. The rotation of the device drives the material to rotate, making the material surface heated evenly. This achieves stable rotation of the material by the device and avoids the situation where uneven heating of the material surface affects the processing efficiency.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a temperature uniformity control device for a heat treatment furnace of nickel-based alloy forgings, including a heating furnace 1. Several supports 101 are fixedly connected to the outer wall of the heating furnace 1. Several heating blocks 102 are fixedly connected to the inner wall of the heating furnace 1 near the supports 101. A clamping mechanism 2 is provided on the inner wall of the heating furnace 1. The position of the heating furnace 1 is fixed by the supports 101 to prevent the heating furnace 1 from changing position during use, which would prevent the device from being used normally.

[0029] The clamping mechanism 2 includes a main board 201, the outer wall of which is rotatably connected to the inner wall of the heating furnace 1. An auxiliary barrel 202 is fixedly connected to the outer wall of the main board 201 near the heating block 102. A threaded rod 203 is rotatably connected to the inner wall of the auxiliary barrel 202. The heating furnace 1 enables the main board 201 to rotate stably, preventing the main board 201 from flipping during rotation and affecting the normal use of the device. A worm gear 204 is fixedly connected to the outer wall of the threaded rod 203 near the auxiliary barrel 202. A threaded barrel 205 is threadedly connected to the outer wall of the threaded rod 203. Several rotating plates 206 are rotatably connected to the inner wall of the threaded barrel 205. A rotating frame 207 is rotatably connected to the inner wall of the end of the rotating plate 206 away from the threaded barrel 205. The rotation of the threaded rod 203 causes the threaded barrel 205 to move, preventing the threaded barrel 205 from being unable to move and thus preventing the device from processing materials normally. A fixing rod 208 is rotatably connected to the inner wall of the end of the rotating frame 207 away from the rotating plate 206. A support bar 209 is fixedly connected to the outer wall of the fixing rod 208. The outer wall of the support bar 209 is fixedly connected to the outer wall of the main plate 201. The position of the fixing rod 208 is fixed by the support bar 209, preventing the fixing rod 208 from falling off during use and causing the device to malfunction.

[0030] A clamping block 210 is fixedly connected to the outer wall of the rotating frame 207 away from the rotating plate 206. The inner wall of the clamping block 210 is provided with several anti-slip grooves 211. A worm gear 212 is rotatably connected to the inner wall of the main board 201 near the auxiliary barrel 202. The outer wall of the worm gear 212 meshes with the outer wall of the worm wheel 204. The rotation of the worm gear 212 drives the worm wheel 204 to rotate stably, preventing the worm wheel 204 from affecting the rotation of the worm gear 212 and causing the device to jam. A rotating mechanism 3 is provided on the outer wall of the heating furnace 1. The rotating mechanism 3 includes a protective shell 301. The outer wall of the protective shell 301 is fixedly connected to the outer wall of the heating furnace 1. A connecting block 307 is fixedly connected to the outer wall of the main board 201 near the protective shell 301. The main board 201 fixes the position of the connecting block 307, preventing the connecting block 307 from falling off during use and causing the device to be unable to rotate.

[0031] A bevel gear 308 is fixedly connected to the outer wall of the connecting block 307 away from the heating block 102. A motor plate 302 is fixedly connected to the outer wall of the heating furnace 1 away from the heating block 102. A controller 303 is fixedly connected to the outer wall of the motor plate 302 away from the heating block 102. A motor 304 is fixedly connected to the outer wall of the motor plate 302 close to the heating block 102. The position of the motor 304 is fixed by the motor plate 302 to prevent the motor 304 from changing position during operation and causing damage. The bottom output shaft of the motor 304 is fixedly connected to a rotating shaft 305 through a coupling. A bevel gear 306 is fixedly connected to the outer wall of the rotating shaft 305 away from the motor 304. The outer wall of the bevel gear 308 meshes with the outer wall of the bevel gear 306. The rotation of the bevel gear 306 drives the rotation of the bevel gear 308, avoiding the problem of the bevel gear 308 affecting the rotation of the bevel gear 306 and causing the device to jam.

[0032] One specific application of this embodiment is:

[0033] When the operator needs to use the equipment, first turn on the heating furnace 1, then place one end of the material in contact with the surface of the clamping block 210 on one side. Next, rotate the worm gear 212, which drives the worm wheel 204 to rotate. The worm wheel 204 drives the threaded rod 203 to rotate, which in turn moves the threaded barrel 205. As the threaded barrel 205 moves, it moves the two rotating plates 206 on both sides, causing them to rotate via the rotating frames 207 on both sides. At this time, the rotating plates 206 also drive the rotating frames 207 to rotate. The fixed rod 208 ensures stable rotation of the rotating frames 207, which in turn drives the clamping block 210 to rotate. The rotation of the clamping block 210 fixes the position of the material, and the anti-slip groove 211 prevents the material from falling off during processing. Then, the heating furnace 1 is turned off, and then multiple heating blocks 102 are started to heat the material. Then, the controller 303 starts the motor 304, which causes the rotating shaft 305 to start rotating. The rotating shaft 305 drives the bevel gear 306 to rotate, and the rotation of the bevel gear 306 drives the second bevel gear 308 to rotate. The second bevel gear 308 drives the connecting block 307 to rotate, and the connecting block 307 drives the main board 201, the auxiliary barrel 202 and the entire device to rotate. The rotation of the device drives the material to rotate, so that the surface of the material is heated evenly.
