Therefore, it is very necessary to design a temperature measuring device and method for an annealing furnace with strong practicality and constant temperature and high temperature protection. Summary of the invention

The fixed spring pieces 9 are evenly distributed in an array on the side of the heating end 4. The electric drive shaft 14 is rotatably connected to the annealing end shell 3. A spring pull rod is arranged on the top surface of the swing rod 15, and one end of the spring pull rod is fixed to the swing rod 15, and the other end of the spring pull rod is fixedly connected to the extension plate 17. Through the above structure, when the heating end 4 is connected to the side of the heating end 4 When the tube is in a heating state, the heat is transferred to the heat transfer sheet 7 through the heating end 4, and then to the permanent magnet column 11 through the heat transfer sheet 7. When the overall heat exceeds the specified temperature, the heat affects the magnetic strength of the permanent magnet column 11, weakening the magnetism of the permanent magnet column 11. When the permanent magnet column 11 weakens to a certain extent, the magnetism of the permanent magnet column 11 is less than the pulling force of the spring slide bar 10. The permanent magnet column 11 is pulled by the pulling force, and the contact sheet 13 on the side of the permanent magnet column 11 is separated from the energized iron block 12, and the heating end 4 is disconnected from the power supply line, so that the overall heating stops, preventing the heating temperature from exceeding the specified value, and the permanent magnet column 11 is permanently closed after the temperature drops. The magnetism of the magnetic column 11 increases, so that the circuit of the heating end 4 is in a connected state, thereby playing a role in constant temperature. When the external motor at the bottom end of the electric drive shaft 14 drives the swing rod 15 to rotate, the swing rod 15 drives the extension plate 17 connected to the end to slide around the sliding track 16, and then the temperature sensor 18 at the end of the extension plate 17 slides along the sliding track 16 to detect the temperature of the space in different areas of the annealing end shell 3. Using the above structure, the circuit connection state is changed by changing the magnetic strength through temperature, thereby playing a role in controlling the temperature, preventing the temperature from being too high and maintaining a constant temperature, while improving the temperature detection range.

Through the above structure, when the permanent magnetic column 11 is affected by temperature and the magnetic When the force is weakened, the other end of the permanent magnet column 11 connects the circuit of the exhaust fan 51, and then the exhaust fan 51 is in working state. When the exhaust fan 51 rotates, the peristaltic shaft 52 and the outer tube-pushing end 53 thereof are driven to rotate. When the tube-pushing end 53 squeezes the suction arc tube 54, the air inside the suction arc tube 54 is repeatedly squeezed upward, and then the suction arc tube 54 draws water from the water tank 56 through the liquid supply pipe 55. The water circulates in the pipeline, and the heat on the side is taken away by the liquid flow, thereby playing a role of cooling. At the same time, the exhaust fan 51 rotates to discharge the internally accumulated heat from the side, and cooperates with the water flow in the pipeline to achieve a better cooling effect.
[0032] Working principle: when the heating tube connected to the side of the heating end 4 is in a heating state, the heat is transferred to the heat transfer sheet 7 through the heating end 4, and then the heat is transferred to the permanent magnet column 11 through the heat transfer sheet 7. When the overall heat exceeds the specified temperature, the heat affects the magnetic strength of the permanent magnet column 11, weakening the magnetism of the permanent magnet column 11. When the permanent magnet column 11 weakens to a certain extent, the magnetism of the permanent magnet column 11 is less than the pulling force of the spring slide bar 10. The permanent magnet column 11 is pulled by the pulling force, and the contact sheet 13 on the side of the permanent magnet column 11 is separated from the energized iron block 12, and the heating end 4 is disconnected from the power supply line, so that the overall heating stops, preventing the heating temperature from rising. When the temperature exceeds the limit value, and the magnetism of the permanent magnet column 11 increases after the temperature drops, the circuit of the heating end 4 is in a connected state, thereby playing a role of constant temperature. When the external motor at the bottom of the electric drive shaft 14 drives the swing rod 15 to rotate, the swing rod 15 drives the extension plate 17 connected at the end to slide around the sliding track 16, and then the temperature sensor 18 at the end of the extension plate 17 slides along the sliding track 16, and the temperature of the space in different areas of the annealing end shell 3 is detected. By using the above structure, the circuit connection state is changed by changing the magnetic strength through temperature, thereby playing a role of controlling the temperature, preventing the temperature from being too high and maintaining a constant temperature.

When the exhaust fan 51 rotates, the peristaltic shaft 52 and the outer tube-pushing end 53 thereof are driven to rotate. When the tube-pushing end 53 squeezes the suction arc tube 54, the air inside the suction arc tube 54 is repeatedly squeezed upward, and water is drawn from the water tank 56 through the liquid supply pipe 55 in the suction arc tube 54. The water circulates in the pipeline, and the heat on the side is taken away by the liquid flow, thereby playing a role of cooling.

7. The measuring method of the temperature measuring device for an annealing furnace according to claim 6, characterized in that: The following steps are involved: S1: Before processing, the parts to be annealed are placed in a storage box (81), and the hydraulic rod (2) pulls the storage box (81) back into the annealing end shell (3) for heating. When the overall heat exceeds a specified temperature, the magnetism of the permanent magnetic column (11) is weakened, and the contact piece (13) on the side of the permanent magnetic column (11) is separated from the energized iron block (12), so that the heating end (4) disconnects the power supply line, and the overall heating stops, preventing the heating temperature from exceeding the specified value; S2: After the processing is completed, the exhaust fan (51) rotates, driving the peristaltic shaft (52) and the outer pipe-pushing end (53) to rotate, so that the air inside the suction arc tube (54) is repeatedly squeezed upward, and then the suction arc tube (54) draws water from the water tank (56) through the liquid supply pipe (55), and the water circulates in the pipe, taking away the heat from the side through the liquid flow, thereby achieving a cooling effect; S3: Subsequently, the exhaust fan (51) exhausts the hot air through the exhaust pipe (62), and the hot air enters the heat collecting cavity tube (64) through the exhaust pipe (62). The heat collected by the heat collecting cavity tube (64) is transferred to the liquid in the heat recovery box (63) through the side heat transfer plate (65), and the dissipated heat is heated and utilized again; S4: Finally, the linkage rotating gear (83) rotates during the meshing movement with the row of teeth (84), and the linkage rotating gear (83) rotates while lifting the sealing plate upward, and the internal parts are pushed out along with the movement of the storage box (81), and the processing is completed.
