[0001] This utility model relates to the field of seamless bearing steel pipe processing technology, and in particular to a novel induction heating automatic feeding device for seamless bearing steel pipes. Background Technology

[0002] Seamless bearing steel tubes are high-precision seamless steel tubes used to manufacture rolling bearing rings. They belong to a subcategory of seamless tubes for mechanical structures. Their core feature is that they meet the extremely high requirements of bearings for strength, wear resistance, dimensional accuracy, and surface quality through high-quality raw materials, precision machining processes, and strict quality control.

[0003] In the existing technology, the steel pipe body needs to be heat-treated during the processing of seamless bearing steel pipe. However, after the seamless bearing steel pipe is processed to the specified temperature, it cannot be automatically fed by induction. This will affect the processing efficiency of the seamless bearing steel pipe if it cannot be processed continuously and stably. Summary of the Invention

[0004] The purpose of this invention is to solve the problem in the existing technology that the seamless bearing steel pipe needs to be heat-treated during the processing of the steel pipe body, but cannot be automatically fed after the seamless bearing steel pipe is processed to the specified temperature, which affects the processing efficiency of the seamless bearing steel pipe. Therefore, a new type of induction heating automatic feeding device for seamless bearing steel pipe is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel induction heating automatic feeding device for seamless bearing steel pipes includes a processing table, a support frame, and a heating body. The support frame is fixedly connected to the bottom of the processing table, and the heating body is fixedly connected to the upper surface of the processing table. A placement box is fixedly connected to the upper surface of the processing table. Multiple seamless bearing steel pipes are stacked on the inner wall of the placement box. An opening is provided on the bottom inner wall of the placement box. A rotating cylinder is rotatably connected to the inner wall of the placement box at the opening. Multiple levers are fixedly connected around the cylinder wall of the rotating cylinder. A first gear is fixedly fitted at the end of the rotating cylinder through the placement box. A bracket is fixedly connected to the side wall of the placement box, and a motor is fixedly connected to the side wall of the bracket. A second gear is fixedly fitted on the output shaft of the motor. The first gear and the second gear are meshed with each other. A control module is provided inside the processing table, and the control module is electrically connected to the motor.

[0007] Preferably, a cover plate is inserted into the top of the placement box, and a sealing rubber frame is fixedly sleeved on the bottom side wall of the cover plate, and the sealing rubber frame is fitted into the inner wall of the placement box.

[0008] Preferably, reinforcing fins are fixedly connected to the gaps between the plurality of the dial plates, and the sidewalls of the reinforcing fins are configured as arc surfaces.

[0009] Preferably, a guide platform is fixedly connected to the bottom inner wall of the placement box, and the upper surface of the guide platform is set as an arc surface.

[0010] Preferably, the processing table has a groove on the inner wall of its top end, a heat-conducting plate is inserted into the inner wall of the groove, multiple heat-conducting fins are fixedly connected to the bottom of the heat-conducting plate, heat-conducting pipes are fixedly connected to the inner walls of the multiple heat-conducting fins, a temperature sensor is fixedly connected to the inner wall of the groove, and the temperature sensor is electrically connected to the control module.

[0011] Preferably, a bimetallic strip is fixedly connected to the inner wall of the groove of the processing table, and a pressure sensor is fixedly connected to the bottom of the groove of the processing table, and the pressure sensor is electrically connected to the control module.

[0012] Compared with the prior art, this utility model provides a novel automatic feeding device for induction heating of seamless bearing steel pipes, which has the following beneficial effects:

[0013] 1. This novel induction heating automatic feeding device for seamless bearing steel pipes starts the motor through the control module. Its output shaft drives the rotating drum to rotate at the bottom opening of the placement box through the meshing of the second gear and the first gear. The deflector plates on the rotating drum rotate with the rotating drum, sequentially pulling the seamless bearing steel pipes in the placement box out of the opening, which can improve the feeding efficiency. The spacing of the deflector plates is matched with the diameter of the steel pipe. Each rotation of the rotating drum allows only a single steel pipe to pass through the opening, avoiding multiple steel pipes falling at the same time and causing jamming.

[0014] 2. This new type of seamless bearing steel pipe induction heating automatic feeding device automatically cuts off the heating power supply when the bimetallic strip deforms due to thermal expansion and contraction if the temperature rises abnormally, thus preventing equipment damage or safety accidents. The heat-conducting plate absorbs and dissipates excess heat from the heating area through heat-conducting fins and heat-conducting pipes, maintaining a stable processing table temperature and extending the service life of the equipment.

[0015] 3. This new type of seamless bearing steel pipe induction heating automatic feeding device reduces the frictional resistance of the steel pipe through the reinforcing fins of the baffle plate gap and the arc surface design, ensuring that a single steel pipe falls smoothly and accurately into the induction heating area of ​​the heating body, thus ensuring the feeding effect. The arc surface of the guide table guides the surface of the seamless bearing steel pipe to slide, which can perform a smoother feeding process and prevent the seamless bearing steel pipe from getting stuck inside the placement box.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A novel induction heating automatic feeding device for seamless bearing steel pipes includes a processing table 1, a support frame 2, and a heating body 7. The support frame 2 is fixedly connected to the bottom of the processing table 1, and the heating body 7 is fixedly connected to the upper surface of the processing table 1. A placement box 3 is fixedly connected to the upper surface of the processing table 1. Multiple seamless bearing steel pipes 4 are stacked on the inner wall of the placement box 3. An opening is opened on the inner wall of the bottom end of the placement box 3. A rotating cylinder 8 is rotatably connected to the inner wall of the placement box 3 at the opening. Multiple levers 9 are fixedly connected around the cylinder wall of the rotating cylinder 8. The end of the rotating cylinder 8 passes through the placement box 3 and is fixedly fitted with a first gear 11. A bracket 12 is fixedly connected to the side wall of the placement box 3. A motor 13 is fixedly connected to the side wall of the bracket 12. A second gear 14 is fixedly fitted on the output shaft of the motor 13. The first gear 11 and the second gear 14 are meshed with each other. A control module 16 is provided inside the processing table 1, and the control module 16 is electrically connected to the motor 13.

[0024] The processing table 1 has a groove on the inner wall of its top end. A heat-conducting plate 17 is inserted into the inner wall of the groove. Multiple heat-conducting fins 18 are fixedly connected to the bottom of the heat-conducting plate 17. Heat-conducting pipes 19 are fixedly connected to the inner walls of the multiple heat-conducting fins 18. A temperature sensor 20 is fixedly connected to the inner wall of the groove of the processing table 1. The temperature sensor 20 is electrically connected to the control module 16. A bimetallic strip 22 is fixedly connected to the inner wall of the groove of the processing table 1. A pressure sensor 21 is fixedly connected to the bottom of the groove of the processing table 1. The pressure sensor 21 is electrically connected to the control module 16.

[0025] When the heating body 7 induction heats the steel pipe, the temperature sensor 20 in the groove of the processing table 1 monitors the temperature of the heating area in real time and transmits the data to the control module 16. When the temperature exceeds the preset threshold, the control module 16 adjusts the heating power to avoid overheating. When heating is finished and material needs to be loaded, the control module 16 starts the motor 13. Its output shaft drives the rotating drum 8 to rotate at the bottom opening of the placement box 3 through the meshing of the second gear 14 and the first gear 11. The paddle 9 on the rotating drum 8 rotates with the rotating drum and sequentially pulls the seamless bearing steel pipe 4 in the placement box 3 out from the opening, which can improve the loading efficiency. The spacing of the paddle 9 matches the diameter of the steel pipe. Each time the rotating drum 8 rotates, only a single steel pipe is allowed to pass through the opening to avoid multiple steel pipes falling at the same time and causing jamming.

[0026] If the temperature rises abnormally, the bimetallic strip 22 will deform due to thermal expansion and contraction, triggering a signal to the control module 16 to automatically cut off the heating power supply, preventing equipment damage or safety accidents. The heat-conducting plate 17 absorbs and dissipates excess heat from the heating area through the heat-conducting fins 18 and heat-conducting pipes 19, maintaining the temperature of the processing table 1 and extending the service life of the equipment.

[0027] To prevent the seamless bearing steel pipe 4 from getting stuck inside the placement box 3, such as Figure 1-5 As shown, a cover plate 5 is inserted into the top of the placement box 3, and a sealing rubber frame 6 is fixedly fitted on the bottom side wall of the cover plate 5. The sealing rubber frame 6 is fitted into the inner wall of the placement box 3. Reinforcing fins 10 are fixedly connected to the gaps of multiple levers 9 respectively. The side wall of the reinforcing fins 10 is set as an arc surface. A guide platform 15 is fixedly connected to the bottom inner wall of the placement box 3. The upper surface of the guide platform 15 is set as an arc surface.

[0028] The cover plate 5 is tightly fitted to the inner wall of the placement box 3 through the sealing rubber frame 6 to prevent dust from entering the box and contaminating the steel pipe. At the same time, it reduces heat loss during the heating process. The reinforcing fins 10 in the gap of the deflector plate 9 reduce the frictional resistance of the steel pipe through the arc surface design, ensuring that a single steel pipe falls smoothly and accurately into the induction heating area of ​​the heating body 7, ensuring the feeding effect. The arc surface of the guide table 15 guides the surface of the seamless bearing steel pipe 4 to slide, which can perform a smoother feeding process and prevent the seamless bearing steel pipe 4 from getting stuck inside the placement box 3.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
