DETAILED DESCRIPTION

[0021] The temperature control device for titanium alloy plate blank forging is characterized by the following: the temperature control device for titanium alloy plate blank forging comprises a heat preservation shell, a vacuum pump, a vacuum breaking valve, a middle frequency power supply, an argon gas filling pipe, an electromagnetic valve, a vacuum gauge, a thermocouple, a heat treatment cavity, an induction coil, a high-temperature-resistant base, a workbench, a fixing rod, a flow guide plate, an inner cavity, an electric cylinder, a connecting plate, a top rod and a through hole.

[0022] Please refer to Figures 1-4This utility model provides an embodiment of a temperature control device for forging titanium alloy slabs, including an insulating shell 1; it also includes an induction coil 12 and a high-temperature resistant base 13. A heat treatment chamber 10 is installed inside the insulating shell 1, and a feed port 11 is opened at one end of the insulating shell 1. The induction coil 12 is installed inside the insulating shell 1. The high-temperature resistant base 13 is installed at the lower end of the inner side of the heat treatment chamber 10, and a worktable 14 is provided at the upper end of the high-temperature resistant base 13. A closed space is maintained by the insulating shell 1 and the worktable 14. The titanium alloy slab is placed and moved by the heat treatment chamber 10 and the worktable 14, so that the heat treatment chamber 10 provides a closed cooling environment for the titanium alloy slab. At the same time, the internal temperature of the heat treatment chamber 10 is maintained by the induction coil 12, thereby improving the cooling quality of the titanium alloy slab.

[0023] Please see Figures 1-3 In this embodiment, a sealing door 2 is installed inside the feed inlet 11, a vacuum pump 3 is installed at the front end of the insulation shell 1, and a vacuum breaking valve 4 is installed at one end of the vacuum pump 3. The vacuum pump 3 and the vacuum breaking valve 4 are connected to the inside of the heat treatment chamber 10. The vacuum pump 3 and the vacuum breaking valve 4 control the gas pressure inside the heat treatment chamber 10 to facilitate subsequent gas filling and cooling. A medium frequency power supply 5 is installed at the front end of the outer side of the insulation shell 1. The medium frequency power supply 5 is electrically connected to the induction coil 12. An argon gas filling pipe 6 is installed at the upper end of the insulation shell 1. The argon gas filling pipe 6 and the insulation shell are connected to each other. A solenoid valve 7 is installed between the heat treatment chamber 1 and the insulation shell 1. The heat treatment chamber 1 is heated by the intermediate frequency power supply 5 and the induction coil 12 to control the temperature inside the heat treatment chamber 10. The solenoid valve 7 controls the argon filling pipe 6 to add argon gas for cooling. A vacuum gauge 8 is installed on the other end of the insulation shell 1. A thermocouple 9 is installed at the lower end of the vacuum gauge 8. One end of the argon filling pipe 6, the vacuum gauge 8 and the thermocouple 9 all extend into the heat treatment chamber 10. The vacuum gauge 8 detects the gas pressure inside the heat treatment chamber 10 to ensure vacuuming, and the thermocouple 9 detects the temperature for precise temperature control.

[0024] Please see Figures 3-4In this embodiment, a fixing rod 15 is fixedly connected to the upper side of the interior of the heat insulation shell 1. A guide plate 16 is installed at the lower end of the fixing rod 15. The fixing rod 15 and the guide plate 16 work together with the argon gas filling pipe 6 to evenly distribute the cooling argon gas. The guide plate 16 has an arc-shaped structure, which helps to evenly distribute the cooling argon gas. An internal cavity 17 is opened on the inner side of the high-temperature resistant base 13. An electric cylinder 18 is installed at the lower end of the internal cavity 17. A connecting plate 19 is installed at the upper end of the electric cylinder 18. The electric cylinder 18 is installed in the internal cavity 17 so that the connecting plate 19 can be moved vertically by the electric cylinder 18. A top rod 20 is fixedly connected to the upper end of the connecting plate 19. A through hole 21 is opened on the worktable 14. The top rod 20 is slidably connected to the worktable 14 through the through hole 21. The connecting plate 19 drives the top rod 20 to move so as to cooperate with the worktable 14 to support the titanium alloy slab.

[0025] Before cooling, first, the sealing door 2 is opened to allow the forged titanium alloy slab to be placed through the feed port 11. Then, the titanium alloy slab is positioned and placed by the worktable 14 and the top rod 20. Next, the air pressure inside the heat treatment chamber 10 is controlled by the vacuum pump 3 and the vacuum breaking valve 4 to facilitate subsequent gas filling and cooling, and to reduce the influence of oxygen on the properties of the titanium alloy slab. Finally, the air pressure inside the heat treatment chamber 10 is detected by the vacuum gauge 8 to ensure vacuuming, and the temperature is detected by the thermocouple 9 for precise temperature control.

[0026] During cooling, firstly, the heat-insulating shell 1 is heated by the intermediate frequency power supply 5 and the induction coil 12 to control the temperature inside the heat treatment chamber 10. Then, the electric cylinder 18 is driven to move the connecting plate 19, which in turn moves the push rod 20 to cooperate with the worktable 14 to support the titanium alloy slab. Then, the solenoid valve 7 controls the argon filling pipe 6 to add argon for cooling. Finally, the guide plate 16 disperses the argon ejected from the argon filling pipe 6 into the heat treatment chamber 10 to prevent the argon from directly impacting the local surface of the titanium alloy product, thus facilitating uniform cooling of the titanium alloy product. Finally, the argon is discharged by the vacuum pump 3 and the vacuum breaking valve 4 to retrieve the titanium alloy slab.

[0027] During use, to prevent argon gas from directly impacting the local surface of the titanium alloy and causing localized cooling, the titanium alloy product can be lifted by the electric cylinder 18 and the push rod 20. The push rod 20 extends from the through hole 21 and lifts the titanium alloy product on the worktable 14, so that the bottom of the titanium alloy is suspended, which further facilitates the uniform heating of the titanium alloy product. In addition, by setting the heat insulation shell 1, the heat loss rate in the heat treatment chamber 10 can be slowed down, thereby ensuring the stability of heat during the heat treatment process and reducing the impact of external temperature changes on the heat treatment.

[0028] Through the above steps, the heat-insulating shell 1 provides a closed space for the titanium alloy slab, and the worktable 14 is used to place and move the titanium alloy slab. The heat treatment chamber 10 provides a closed vacuum cooling environment for the titanium alloy slab. At the same time, the induction coil 12 is used to maintain the internal temperature of the heat treatment chamber 10, thereby improving the cooling quality of the titanium alloy slab. This solves the problem that most existing temperature control devices for titanium alloy slab forging are equipped with open material platforms and gas nozzles. During use, the open space often results in uneven distribution of cooling argon gas, causing uneven temperature changes in the overall titanium alloy slab, which affects the processing quality of titanium alloy products and leads to a decrease in the effectiveness of temperature control devices for titanium alloy slab forging.
