[0002] Quenching is a metal heat treatment process, which refers to the process of heating a metal workpiece to a certain appropriate temperature and maintaining it for a period of time, and then immersing it in a quenching medium for rapid cooling to change its surface or internal microstructure to obtain the desired properties. The quenching furnace is an indispensable equipment in the quenching work. The quenching furnace is a furnace for heating the workpiece before quenching.

The base has a lifting assembly and a feeding assembly that cooperate with each other. The feeding assembly can transport materials without manual feeding, thereby reducing the labor intensity of users. Different materials can be distinguished by the dividing plate arranged above the conveyor belt to avoid materials from piling up, so that the thickness of the added materials is uniform. An automated feeding method is used to replace manual feeding, which is not easy to scald users and is easy to operate. It improves the utilization rate of equipment, reduces production costs, ensures service life, reduces labor intensity, and improves production efficiency, thereby ensuring the quenching quality of the quenching furnace.

The servo motor 2021 is embedded and installed on one side of the connecting plate 201, and the output shaft of the servo motor 2021 is transmission-connected to the connecting disk 202 through a chain, and the outside of the connecting disk 202 and the outside of the output shaft of the servo motor 2021 are connected. Sprockets meshing with the chain are nested and arranged, an electric cylinder 2022 is embedded and installed at the lower edge of the through groove of the connecting plate 202, a clamping plate A2023 is fixedly installed above the electric cylinder 2022, and the other side of the clamping plate A2023 extends to the other side of the connecting plate 201, a clamping plate B2024 is fixedly installed on the other side of the connecting plate 201, and ceramic gaskets are fixedly installed above the other side of the clamping plate B2024 and below the other side of the clamping plate A2023, a groove 103 is embedded and arranged on one side of the interior of the quenching furnace 102, a servo electric cylinder A1031 is embedded and installed on the back of the groove 103, and a quenching induction coil 1032 is installed at the end of the servo electric cylinder A1031 through a mounting plate;

[0025] The staff sends one end of the workpiece between the clamp A2023 and the clamp B2024 on one side of a connecting disk 202. The electric cylinder 2022 contracts to drive the clamp A2023 to move down, so that the ceramic gasket under the clamp A2023 and the ceramic gasket above the clamp B2024 are tightly clamped on the upper and lower sides of the workpiece respectively, and the workpiece is fixed between the clamp A2023 and the clamp B2024. Continue the above work and fix the other workpiece between the clamp A2023 and the clamp B2024 on the other side of the connecting disk 202.

A spray rack 1012 is installed on the top of the quenching furnace 102, and the spray rack 1012 is connected to the outlet pipeline of the chiller 1011.

[0029] The circulating water pump 101 works to guide the water inside the water tank 1 into the chiller 1011 for cooling. The cooling water inside the chiller 1011 is sprayed onto the surface of the workpiece through the spray rack 1012 to quickly cool the workpiece. The servo motor 2021 drives the connecting plate 202 to rotate forward and reverse, thereby causing the workpiece to rotate forward and reverse, so that the surface of the workpiece is evenly in contact with the cooling water, resulting in a better cooling effect.

[0030] Reference Figure 1 , 3 5. In this embodiment, a discharge plate 104 is rotatably connected to the inlet of the water tank 1 through a rotating shaft, and one side of the discharge plate 104 extends to the outside of the water tank 1 through an opening, and a plurality of punching holes are arranged on the surface of the discharge plate 104 corresponding to the outlet of the quenching furnace 102. A servo electric cylinder B1041 is symmetrically rotatably connected to the outside of the water tank 1 through a rotating shaft, and the upper end of the servo electric cylinder B1041 is rotatably connected to the discharge plate 104 through a rotating shaft. A conveyor belt 1042 is installed on the outside of the water tank 1 at a position corresponding to the discharge plate 104.

[0031] When the workpiece is cooled, excess water flows into the water tank 1 through the punched holes on the surface of the unloading plate 104 for recovery. After the workpiece is quenched, the corresponding electric cylinder 2022 extends, driving the clamp A2023 to move up and away from the workpiece, and the workpiece falls onto the unloading plate 104. Then, the servo electric cylinder B1041 contracts, driving the unloading plate 104 to tilt, and the workpiece above the unloading plate 104 slides onto the conveyor belt 1042, and the conveyor belt 1042 unloads the workpiece.

The quenching induction coil 1032 generates eddy currents with a high current density on the surface of the workpiece to heat the surface of the workpiece. After the workpiece is heated for a period of time, the servo electric cylinder A1031 contracts and drives the quenching induction coil 1032 to return to the inside of the groove 103. The baffle 1033 is reset to block the opening of the groove 103 under the action of the spring, blocking the quenching induction coil 1032, and then the circulating water pump 101 works to pump water. The water inside the tank 1 is introduced into the chiller 1011 for cooling. The cooling water inside the chiller 1011 is sprayed on the surface of the workpiece through the spray rack 1012 to quickly cool the workpiece. The servo motor 2021 drives the connecting plate 202 to rotate forward and reverse, thereby causing the workpiece to rotate forward and reverse, so that the surface of the workpiece is evenly in contact with the cooling water. Excess water flows into the tank 1 through the punching holes on the surface of the unloading plate 104 for recovery. After the workpiece is cooled, the corresponding electric cylinder 2022 extends, driving the clamping plate A2023 to move up and away from the workpiece, and the workpiece falls onto the unloading plate 104. Then the servo electric cylinder B1041 contracts, driving the unloading plate 104 to tilt, and the unloading The workpiece above the material plate 104 slides onto the conveyor belt 1042, and the conveyor belt 1042 unloads the workpiece. Finally, the motor 2 works to drive the connecting plate 201 to rotate 180°, and another workpiece is sent into the quenching furnace 102 for quenching. During this period, the staff installs the new workpiece between the clamp A2023 and the clamp B2024 on one side of the idle connecting disk 202. The two connecting plates 201 work alternately to continuously quench the workpiece. While quenching one workpiece, the staff has sufficient time to install the workpiece to be quenched on one side of the other connecting disk 202, making the quenching work more efficient.
