Technical Field

[0001] This utility model relates to the field of vacuum furnaces, and in particular to an intelligent vacuum furnace for metal product processing. Background Technology

[0002] When processing metal products, vacuum furnaces can provide a vacuum environment to perform high-temperature treatment on the metal products, thereby improving the purity of the metal, enhancing its physical and chemical properties, and reducing porosity and structural inhomogeneity. The vacuum environment can effectively prevent metal oxidation and contamination, while promoting the evaporation and extraction of impurities on the metal surface, thus ensuring the high quality and high performance of the metal products.

[0003] In existing vacuum furnaces, many tasks still require manual operation when processing metal products. This excessive human intervention can easily lead to instability in the melting process, making it impossible to fully follow the process curve and thus affecting product quality.

[0004] Therefore, given that the existing vacuum furnaces suffer from excessive human intervention, which can easily lead to instability in the melting process, an intelligent vacuum furnace for metal product processing can be designed. By integrating the various components of the vacuum furnace through a control mechanism, the aforementioned problems can be easily solved. Utility Model Content

[0021] Please see Figures 1-4This utility model provides an embodiment of an intelligent vacuum furnace for metal product processing, comprising a furnace body 1, a ceramic rack 4, a vacuum suction mechanism 5, a cooling mechanism 6, and a control mechanism 7; the furnace body 1 has a vacuum furnace chamber 3 inside, and the vacuum furnace chamber 3 is fitted with a sealing door 2, which is matched and fastened to the furnace body 1; the vacuum furnace chamber 3 has a ceramic rack 4 for placing metal products inside; a vacuum suction mechanism 5 for sucking air from inside the furnace body 1 is installed on one side of the furnace body 1; a cooling mechanism 6 for rapidly cooling metal products is installed on the other side of the furnace body 1; and a control mechanism 7 for controlling the vacuum furnace is located at the top front end of the furnace body 1.

[0022] Please see Figures 1-2 In this embodiment, the top of the furnace body 1 is provided with a suction connector 20 and a cooling connector 25, which are symmetrically arranged along the top of the furnace body 1. A temperature measuring hole 21 is provided between the suction connector 20 and the cooling connector 25. A panel frame 13 is provided at the front edge of the top of the furnace body 1, and a panel slot 14 is provided in the center of the panel frame 13. By combining the suction connector 20 and the cooling connector 25, the furnace body 1 can be connected to a vacuum suction mechanism 5 for suctioning air from inside the furnace body 1 through the suction connector 20, and to a cooling mechanism 6 for rapid cooling of metal products through the cooling connector 25 during installation. A ceramic heating wall 10 is attached to the inner wall of the vacuum furnace chamber 3, and a heat conduction groove 8 is provided at the bottom of the furnace body 1. The interior of the heat conduction groove 8 is provided with a ceramic heating wall 10. There is a corresponding ceramic heating wall 10 with an electrically conductive ring 9. The center of the electrically conductive ring 9 is equipped with a storage battery. The inner side of the sealing door 2 is fitted with a sealing sticker 11, and the outer end of the sealing door 2 is equipped with a handle 12. By combining the ceramic heating wall 10 and the electrically conductive ring 9, after the operator places the metal product on the ceramic rack 4, the storage battery supplies power to the electrically conductive ring 9. The electrically conductive ring 9 conducts heat through the ceramic heating wall 10 to the vacuum furnace 3, thereby increasing the temperature of the vacuum furnace 3 to process the metal product. By combining the sealing door 2, the sealing sticker 11 and the handle 12, the operator can pull the handle 12 to move the sealing door 2 so that the sealing sticker 11 can seal the vacuum furnace 3, preventing outside air from entering the interior of the vacuum furnace 3.

[0023] Please see Figures 2-3In this embodiment, the vacuum suction mechanism 5 includes a vacuum suction pipe 19. A vacuum pump 15 is located at the lower end of the vacuum suction pipe 19. A suction port 17 and an exhaust port 16 are respectively opened at the rear end of the vacuum pump 15. The lower end of the vacuum suction pipe 19 is connected to the vacuum pump 15 through the suction port 17. An exhaust pipe 18 is provided inside the exhaust port 16. The upper end of the vacuum suction pipe 19 extends into the suction connector 20. By combining the vacuum pump 15 and the vacuum suction pipe 19, when the vacuum furnace is working, the control mechanism 7 controls the vacuum pump 15 to be powered on, causing the vacuum pump 15 to draw air from the vacuum furnace chamber 3 through the vacuum suction pipe 19. The nitrogen gas is discharged outward through the exhaust pipe 18 of the exhaust port 16, thereby creating a vacuum environment inside the vacuum furnace 3. The cooling mechanism 6 includes a nitrogen cooling pipe 23, a nitrogen tank 22 at the lower end of the nitrogen cooling pipe 23, a solenoid valve 24 in the middle section of the nitrogen tank 22, and the upper end of the nitrogen cooling pipe 23 extends into the interior of the cooling joint 25. By combining the nitrogen cooling pipe 23 with the solenoid valve 24, after the metal products are processed, the operator can control the solenoid valve 24 to open through the control mechanism 7, so that the low-temperature nitrogen gas in the nitrogen tank 22 enters the vacuum furnace 3 through the nitrogen cooling pipe 23, thereby rapidly reducing the temperature of the metal products.

[0024] Please see Figures 3-4In this embodiment, the control mechanism 7 includes a control panel 26, which engages with the panel slot 14.

The surface of the circuit board 27 is sequentially provided with a control element 28 (model S7-400), a wireless module 29 (model Ai-M62), a temperature sensor 30 (model PT100), and a storage unit 33. A ribbon cable 32 connects the circuit board 27 and the control panel 26 electrically. A battery pack 31 is located at the bottom of the circuit board 27. The combination of the control panel 26, control element 28, wireless module 29, storage unit 33, and battery pack 31 allows operators to control various components of the vacuum furnace via the control element 28 on the control panel 26 during operation. The vacuum furnace is controlled by a wireless module 29, which transmits the processing data of the vacuum furnace to the control terminal via a wireless network. The wireless module 29 also allows operators to remotely control the vacuum furnace via the wireless terminal. A battery pack 31 provides power to the control mechanism 7, enabling operators to control the control panel 26. A temperature probe 36 is installed inside the temperature measuring hole 21, with its lower end extending into the vacuum furnace chamber 3. A connecting cable 35 connects the circuit board 27 and the temperature probe 36. A rear cover 34 is fitted to the rear of the control panel 26. The temperature probe 36 is combined with a temperature sensor 30, allowing the temperature sensor 30 to monitor the temperature inside the vacuum furnace chamber 3 in real time during operation, facilitating timely temperature adjustments.

[0025] During operation, the staff places the metal products on the ceramic rack 4, and the battery supplies power to the electric heat conduction ring 9. The electric heat conduction ring 9 conducts heat through the ceramic heating wall 10 to the vacuum furnace 3, thereby increasing the temperature of the vacuum furnace 3 to process the metal products.

[0026] The control mechanism 7 controls the power supply of the vacuum pump 15, so that the vacuum pump 15 draws air from the vacuum furnace 3 through the vacuum suction pipe 19 and discharges it to the outside through the exhaust pipe 18 of the exhaust port 16, thereby creating a vacuum environment in the vacuum furnace 3.

[0027] After the metal products are processed, the staff can control the solenoid valve 24 to open through the control mechanism 7, so that the low temperature nitrogen in the nitrogen tank 22 enters the vacuum furnace 3 through the nitrogen cooling pipe 23, which rapidly reduces the temperature of the metal products.

[0028] During operation, staff can control various components of the vacuum furnace through the control element 28 on the control panel 26. The processing data of the vacuum furnace is transmitted to the control terminal via the wireless module 29 through the wireless network. At the same time, the staff can remotely control the vacuum furnace through the wireless terminal via the wireless module 29. The temperature sensor 30 monitors the temperature inside the vacuum furnace chamber 3 in real time through the temperature probe 36, so as to make timely adjustments to the temperature inside the vacuum furnace chamber 3.

[0029] Through the above steps, this application combines the furnace body 1, ceramic rack 4, vacuum suction mechanism 5, cooling mechanism 6, and control mechanism 7, enabling operators to control various components of the vacuum furnace via the control element 28 of the control panel 26 during metal product processing. The processing data of the vacuum furnace is transmitted to the control terminal via a wireless network through the wireless module 29. Simultaneously, the wireless module 29 allows operators to remotely control the vacuum furnace via a wireless terminal. The temperature sensor 30 monitors the temperature inside the vacuum furnace chamber 3 in real time via the temperature probe 36, facilitating timely temperature adjustments. Operators place the metal product on the ceramic rack 4 inside the vacuum furnace chamber 3, and the vacuum suction mechanism 5 extracts and removes air from the vacuum furnace chamber 3, creating a vacuum environment. After the metal product processing is completed, the cooling mechanism 6 rapidly cools and lowers the metal product.
