[0029] Embodiment

[0030] Reference Figures 1-4 For one embodiment of the present application, a blade machining quenching and uniform temperature device is provided, comprising:

[0031] The circulating unit 100 comprises a quenching tank 101 and a buffer tank 102 arranged on one side of the quenching tank 101, the buffer tank 102 is communicated with the quenching tank 101 through a communication hole 103, a water temperature sensor 104 is arranged in the quenching tank 101, a water outlet pipe 105 is communicated with the quenching tank 101, a circulating pump 106 is installed at one end of the water outlet pipe 105, a serpentine water pipe 107 is communicated with the output end of the circulating pump 106, and the serpentine water pipe 107 is arranged in a continuous and bent serpentine path.

[0032] The serpentine water pipe 107 has a water inlet 108 and a water outlet 109, the water inlet 108 of the serpentine water pipe 107 is communicated with the output end of the circulating pump 106, the water outlet 109 of the serpentine water pipe 107 is communicated with the quenching tank 101, and the connection between the water outlet 109 of the serpentine water pipe 107 and the quenching tank 101 is located at the lower part of the quenching tank 101.

[0033] The serpentine water pipe 107 is provided with a plurality of cooling fins 110 arranged in sequence along the extension direction of the serpentine water pipe 107, and the serpentine water pipe 107 penetrates each cooling fin 110.

[0034] The communication hole 103 is located at the upper part of the buffer tank 102, and the water outlet pipe 105 is connected to the lower part of the buffer tank 102.

[0035] The upper water pipe 201 is provided with an upper water inlet 202 on the pipe wall, and a piston 203 is slidably arranged in the upper water pipe 201 to close the upper water inlet 202.

[0036] The upper water unit 200 comprises an upper water pipe 201, one end of which extends into the buffer tank 102, and the upper water pipe 201 is connected to an external water source.

[0037] The upper water pipe 201 is fixedly connected with a bracket 204, the bracket 204 is rotatably connected with a lever 205, one end of the lever 205 is movably mounted with a floating ball 206, the other end of the lever 205 is provided with a connecting groove 207, the piston 203 is fixedly connected with a connecting rod 208, the top of the connecting rod 208 is fixedly connected with a synchronous ring 209, and the synchronous ring 209 passes through the connecting groove 207.

[0038] During use, the quenching tank 101 and the buffer tank 102 are filled with water, the water temperature sensor 104 monitors the water temperature in the quenching tank 101 in real time, the piston 203 of the upper water unit 200 is in a closed state, the floating ball 206 floats on the water surface in the buffer tank 102, and the lever 205 keeps balance.

[0039] When the blade is placed in the quenching tank 101 for quenching, the heat of the blade is transferred to the water in the quenching tank 101, causing the water temperature to rise.

[0040] The water with increased temperature in the quenching tank 101 enters the buffer tank 102 through the communication hole 103, the circulating pump 106 is started, and the water in the buffer tank 102 is pumped out through the water outlet pipe 105 and delivered to the serpentine water pipe 107. The water flows in the serpentine water pipe 107, and the heat is dissipated to the surrounding environment through the cooling fins 110. The cooled water flows back to the lower part of the quenching tank 101 from the water outlet 109 of the serpentine water pipe 107, and since the water outlet 109 is located at the lower part, the cold water gradually replaces the hot water in the quenching tank 101 from bottom to top, achieving uniform distribution of water temperature.

[0041] As the quenching operation continues, the water in the quenching tank 101 will decrease due to evaporation and other reasons, causing the water level in the buffer tank 102 to drop. The floating ball 206 drops as the water level drops, causing the lever 205 to rotate downward at one end and upward at the other end. The upwardly rotating end of the lever 205 pushes the piston 203 upward through the connecting groove 207, the synchronizing ring 209, and the connecting rod 208, opening the water inlet 202 of the water inlet pipe 201 and starting the external water source to replenish the water in the buffer tank 102. When the water level in the buffer tank 102 rises to a certain extent, the floating ball 206 rises, causing the lever 205 to rotate in the opposite direction, and the piston 203 to move downward to close the water inlet 202 and stop the replenishment of water.

[0042] During the entire quenching process, the water temperature sensor 104 continuously monitors the water temperature in the quenching tank 101. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application, and they should be included in the scope of the claims of the present application.
