Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel rolling technology, and in particular to a stainless steel rolling heating device. Background Technology
[0002] Stainless steel rolling refers to the process of plastically deforming heated stainless steel billets using a rolling mill to press them into the required shapes such as plates, wires, and profiles. Rolling is one of the core processes in stainless steel processing, and it can effectively improve the mechanical properties, surface quality, and dimensional accuracy of stainless steel.
[0003] A search revealed Chinese patent CN220781822U, which discloses a heating device for stainless steel rolling. This patent reduces energy waste and lowers energy consumption and operating costs by installing rotating doors on both sides of the heating chamber to block the inlet and outlet. However, each time material is fed in or out, the sealed doors are briefly open, causing heat to escape from the heating chamber. To advance industry technology, better reduce heat loss during feeding and discharging, and enhance core technological competitiveness, this application proposes a new implementation scheme for a stainless steel rolling heating device that differs from existing technologies. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an apparatus to solve one or more problems in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A stainless steel rolling heating device includes a placement rack and a heating box. A mounting box is snapped into the bottom of the heating box, and multiple heating tubes are bolted between the inner walls of both sides of the mounting box. A first sealing door is rotatably connected to one side of the heating box, and a second sealing door is rotatably connected to the bottom of the first sealing door. A baffle plate is fixedly connected to the outer wall of one side of the second sealing door. A third sealing door is rotatably connected to the other side of the heating box, and a fourth sealing door is rotatably connected to the bottom of the third sealing door. An infrared transmitter and an infrared receiver are fixedly connected to one end of the heating box, with the infrared transmitter and receiver positioned opposite each other. The baffle plate is located between the infrared transmitter and receiver. An air outlet pipe is fixedly connected between the outer wall of one end of the heating box and the inner walls of both sides of the heating box. Multiple nozzles are threaded to the bottom of the air outlet pipe. An air pump is fixedly connected to the outer wall of the top of the heating box, and a diverter pipe is sealed and inserted into the air outlet end of the air pump. Both ends of the diverter pipe are respectively inserted into the air outlet pipe.
[0007] Furthermore, the top of the placement frame is fixedly connected to multiple mounting blocks, and a lead screw is rotatably mounted between two mounting blocks via an interlocking bearing. The outer wall of the lead screw is threaded with a first slider. A motor is fixedly connected to one side of one of the mounting blocks, and the output end of the motor is fixedly connected to one end of the lead screw.
[0008] Furthermore, a sliding rod is fixedly connected between the other two mounting blocks, and a second slider is slidably sleeved on the outer wall of the sliding rod. An electric telescopic rod is fixedly connected to the top of both the second and first sliders. The top of the two electric telescopic rods is fixedly connected to the same connecting plate, and an L-shaped mounting plate is fixedly connected to the bottom of the connecting plate. A push plate is fixedly connected to the other end of the L-shaped mounting plate.
[0009] Furthermore, a connecting rod is fixedly connected to one side of the push plate, and the other end of the connecting rod is fixedly connected to one side of the connecting plate.
[0010] Furthermore, a control panel and a processor are fixedly connected to one side of the outer wall of the heating box. The processor is electrically connected to the control panel, motor, electric telescopic rod, infrared transmitter, and infrared receiver.
[0011] Furthermore, a temperature controller is fixedly connected inside the heating box, and the temperature controller is electrically connected to the heating tube.
[0012] Furthermore, limit blocks are fixedly connected to one end and both inner walls of the heating box. Two limit blocks are located on the outside of the first sealing door, and the other two limit blocks are located on the inside of the third sealing door.
[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0014] 1. After receiving the signal emitted by the infrared transmitter through the infrared receiver, the processor controls the air pump to start. Under the action of the air pump, the gas is input into the diversion pipe, and then into the outlet pipe. Then, the gas is sprayed out from the nozzle, thus forming an air curtain on both sides of the heating box located at the first and second sealing doors. This prevents the heat inside the heating box from spreading outward and also prevents the external temperature from affecting the temperature inside the heating box, so as not to affect the temperature of the stainless steel plate.
[0015] 2. Driven by the electric telescopic rod, the connecting plate, L-shaped mounting plate, and push plate move downwards, so that the push plate is placed on one side of the stainless steel plate. Then, driven by the motor, the lead screw rotates, thereby driving the first slider and the second slider to move, which in turn drives the push plate to move, making it convenient and quick to push the stainless steel plate.
[0016] 3. By setting the first, second, third, and fourth sealing doors to open in stages, the extent to which the sealing doors open can be greatly reduced, thereby reducing heat loss. Attached Figure Description

[0023] Reference Figures 1-4A stainless steel rolling heating device includes a placement rack 1 and a heating box 12. The bottom of the heating box 12 is snapped with an installation box 24. Multiple heating tubes 25 are fixed between the inner walls of the two sides of the installation box 24 by bolts. A first sealing door 15 is rotatably connected to one side of the heating box 12. A second sealing door 1501 is rotatably connected to the bottom of the first sealing door 15. A baffle plate 19 is fixed to the outer wall of one side of the second sealing door 1501 by bolts. A third sealing door 16 is rotatably connected to the other side of the heating box 12. A fourth sealing door 1601 is rotatably connected to the bottom of the third sealing door 16.
[0024] An infrared transmitter 18 and an infrared receiver 1801 are fixed to one end of the heating box 12 by bolts. The infrared transmitter 18 is model 61-238 / RSGCBKC-B02 / ET, and the infrared receiver 1801 is model TSOP57xxxE. The infrared transmitter 18 and the infrared receiver 1801 are arranged opposite to each other, and the baffle plate 19 is located between the infrared transmitter 18 and the infrared receiver 1801.
[0025] When the shield 19 is not blocking the infrared transmitter 18 and the infrared receiver 1801, the infrared receiver 1801 will receive the signal emitted by the infrared transmitter 18.
[0026] An air outlet pipe 22 is bolted between the outer wall of one end of the heating box 12 and the inner walls of both sides of the heating box 12. Multiple nozzles 23 are threaded to the bottom of the air outlet pipe 22. An air pump 20 is bolted to the outer wall of the top of the heating box 12. A diverter pipe 21 is sealed and inserted into the air outlet end of the air pump 20. Both ends of the diverter pipe 21 are inserted into the air outlet pipe 22 respectively.
[0027] Under the action of the air pump 20, the gas is input into the diversion pipe 21, and then into the outlet pipe 22 through the diversion pipe 21. Then, the gas is sprayed out from the nozzle 23, thereby forming an air curtain on both sides of the heating box 12, thereby reducing the heat diffusion from the heating box 12 to the outside, and preventing the external temperature from affecting the temperature inside the heating box 12 and reducing heat exchange.
[0028] Multiple mounting blocks 2 are welded to the top of the placement frame 1. A lead screw 3 is rotatably mounted between two mounting blocks 2 via an interlocking bearing. A first slider 5 is threadedly connected to the outer wall of the lead screw 3. A motor 6 is bolted to one side of one of the mounting blocks 2. The output end of the motor 6 is fixedly connected to one end of the lead screw 3. A sliding rod 4 is welded between the other two mounting blocks 2. A second slider is slidably sleeved on the outer wall of the sliding rod 4. An electric telescopic rod 7 is bolted to the top of both the second slider and the first slider 5. The top ends of the two electric telescopic rods 7 are bolted to the same connecting plate 8. An L-shaped mounting plate 9 is welded to the bottom of the connecting plate 8. A push plate 10 is welded to the other end of the L-shaped mounting plate 9. A connecting rod 11 is welded to one side of the push plate 10. The other end of the connecting rod 11 is fixedly connected to one side of the connecting plate 8. The connecting plate 8, the L-shaped mounting plate 9, the push plate 10, and the connecting rod 11 are all made of high-temperature resistant metal plates. The material can be selected according to the actual situation and cost.
[0029] Driven by the electric telescopic rod 7, the connecting plate 8, the L-shaped mounting plate 9 and the push plate 10 move downward, so that the push plate 10 is placed on one side of the stainless steel plate. Then, driven by the motor 6, the lead screw 3 rotates, thereby driving the first slider 5 and the second slider to move, and then driving the push plate 10 to move, so as to facilitate pushing the stainless steel plate.
[0030] A control panel 13 and a processor 14 are fixed to one side of the outer wall of the heating box 12 by bolts. The processor 14 is model ARM9TDMI. The processor 14 is electrically connected to the control panel 13, the motor 6, the electric telescopic rod 7, the infrared transmitter 18, and the infrared receiver 1801. A temperature controller is fixed inside the heating box 12 by bolts. The temperature controller is model W3003. The temperature controller is electrically connected to the heating tube 25.
[0031] Limiting blocks 17 are welded to one end and both sides of the inner wall of the heating box 12. Two limiting blocks 17 are located outside the first sealing door 15, and the other two limiting blocks 17 are located inside the third sealing door 16. The limiting blocks 17 limit the closing of the first sealing door 15 and the third sealing door 16 to ensure the sealing between the first sealing door 15 and the third sealing door 16 and the heating box 12.
[0032] The working principle of this embodiment is as follows: During use, the first sealing door 15, the second sealing door 1501, the third sealing door 16, and the fourth sealing door 1601 are in the closed state. At this time, the baffle plate 19 blocks the infrared receiver 1801 and the infrared transmitter 18, and the infrared receiver 1801 cannot receive the signal emitted by the infrared transmitter 18. First, the stainless steel plate is placed on the placement rack 1. Then, the processor 14 controls the electric telescopic rod 7 to start. Driven by the electric telescopic rod 7, the connecting plate 8, the L-shaped mounting plate 9, and the push plate 10 move downward, so that the push plate 10 is placed on one side of the stainless steel plate. Then, the processor 14 controls the motor 6 to start. Driven by the motor 6, the lead screw 3 rotates, thereby driving the first slider 5 and the second slider to move, which in turn drives the push plate 10 to move, thereby pushing the stainless steel plate to move. Under the push of the stainless steel plate, the second sealing door 1601 is moved. As the second sealing door 1501 opens wider, it contacts the connecting rod 11. Continuing to push, the first sealing door 15 also rotates slightly inward, allowing the stainless steel plate to be pushed into the heating chamber 12. At this time, the baffle 19 will not block the infrared transmitter 18 and the infrared receiver 1801. The infrared receiver 1801 will receive the signal emitted by the infrared transmitter 18 and then transmit the information to the processor 14 for processing. Next, the processor 14 controls the air pump 20 to start, and under the action of the air pump 20, gas is input into the diversion pipe 21, and then into the outlet pipe 22. The gas is then ejected from the nozzle 23, forming an air curtain on both sides of the heating chamber 12, thus preventing heat from spreading outwards and preventing external temperatures from affecting the temperature inside the heating chamber 12.
[0033] After the stainless steel plate is pushed into the heating chamber 12, the pusher plate 10 is pushed out of the heating chamber 12 by the motor 6. Then, the first sealing door 15, the second sealing door 1501, the third sealing door 16, and the fourth sealing door 1601 fall downwards under their own gravity, thus sealing the heating chamber 12. Next, the heating tube 25 inside the heating chamber 12 heats the stainless steel plate. After the stainless steel plate is heated, the pusher plate 10 is sent into the heating chamber 12 by the motor 6. Then, the pusher plate 10 is lowered to one side of the stainless steel plate by the electric telescopic rod 7. Then, the screw 3 driven by the motor 6 rotates, causing the pusher plate 10 to push forward, thus pushing the stainless steel plate outward. Under the push of the stainless steel plate, the third sealing door 16 rotates outward. Then, the third sealing door 16 will drive the fourth sealing door 1601 to open outward, so as to push the stainless steel plate out of the heating chamber 12. At this time, the air curtain is also activated to prevent the exchange of temperature between the inside and outside of the heating chamber 12. The stainless steel plate is then pushed out of the heating chamber 12 and pushed to the next production line for further processing.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
