[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 4-6To adapt to workpieces of different sizes, this embodiment provides the following technical solution, specifically: A horizontally arranged bearing plate 4 is installed on the upper surface of the operating platform 1. A fixed limiting plate 11 and a movable limiting plate 19 are installed inside the bearing plate 4. The fixed limiting plate 11 and the movable limiting plate 19 cooperate to clamp the workpiece body 13 that needs to be quenched. An adjustment mechanism for adjusting the position of the movable limiting plate 19 is provided inside the bearing plate 4. The adjustment mechanism includes a mounting frame 12 fixedly installed inside the bearing plate 4. A limiting protrusion 16 is fixedly installed on the upper surface of the mounting frame 12. An adjustment block 14 is provided above the limiting protrusion 16. The adjustment block 14 forms a sliding structure with the limiting protrusion 16 through a limiting groove 15 opened on its lower surface. A fixed magnetic strip 17 is fixedly installed on the upper surface of the limiting protrusion 16. The fixed magnetic strip 17 is magnetically attracted and fixed to the adjustment block 14. A horizontally arranged connecting bolt 18 is threaded through the upper end of the adjustment block 14. The front end of the connecting bolt 18 is rotatably connected to the movable limiting plate 19.

[0027] Before using the device, first select an appropriate number of adjusting blocks 14 according to the size of the workpiece body 13. Then slide the corresponding number of adjusting blocks 14 to the right on the mounting frame 12 (at this time, the limiting groove 15 below the adjusting block 14 slides relative to the limiting protrusion 16 above the mounting frame 12). After moving to the designated position, use the magnetic attraction of the fixed magnetic strip 17 to attract and fix the adjusting block 14. Then rotate the connecting bolt 18, and use the threaded engagement between the connecting bolt 18 and the adjusting block 14 to push the movable limiting plate 19 to move. Finally, use the movable limiting plate 19 and the fixed limiting plate 11 to clamp and fix the workpiece body 13.

[0028] Example 2: Please refer to Figures 1-3 In order to achieve the purpose of quenching the workpiece, this embodiment provides the following technical solution, which specifically discloses: an operating platform 1 placed horizontally on the ground, an electrical control box 2 and a high-frequency furnace 3 fixedly installed on the upper surface of the operating platform 1, an induction heater 6 and a cooling nozzle 7 fixedly installed on the front surface of the high-frequency furnace 3, the position of the cooling nozzle 7 corresponding to the position of the induction heater 6, an electric slide rail 5 fixedly installed on the upper surface of the operating platform 1, and a slidable connection between the bearing plate 4 and the electric slide rail 5, the cooling nozzle 7 being connected to a water storage tank 9 fixedly installed on the upper surface of the operating platform 1 through a conveying pipe 8, and a return pipe 10 connected to the bearing plate 4 being installed on the side of the water storage tank 9.

[0029] After the workpiece body 13 is clamped, the electric slide rail 5 above the operating platform 1 is turned on. The electric slide rail 5 drives the bearing plate 4 to move from left to right, thereby driving the workpiece body 13 past the induction heater 6. The induction heater 6 rapidly heats the workpiece. At the same time, the water pump above the water storage tank 9 is turned on. Under the action of the water pump, the cooling water in the water storage tank 9 is transported to the cooling nozzle 7 through the delivery pipe 8 and sprayed out. The sprayed cooling water is used to quickly cool the workpiece to achieve the purpose of quenching. The used cooling water is collected by the bearing plate 4 and returned to the water storage tank 9 through the return pipe 10 for recycling.

[0030] The heating principle of high-frequency furnace 3 is as follows:

[0031] High-frequency power generation: The device converts the power frequency (50 / 60Hz) AC power into high-frequency (usually from tens of kilohertz to hundreds of kilohertz) AC power through rectifier and inverter circuits.

[0032] Induction heating: High-frequency current is supplied to the induction coil. The induction coil is specially designed according to the shape of the workpiece (such as circular, planar, or contoured). When the workpiece is placed or brought close to the induction coil, eddy currents are rapidly generated on the surface of the workpiece under the action of the high-frequency alternating magnetic field, causing it to heat up.

[0033] Rapid heating: Because energy is highly concentrated on the surface, the surface of the workpiece can be rapidly heated to the temperature required for quenching (e.g., the austenitizing temperature of steel, about 800-1000℃) within seconds, while the internal temperature of the workpiece changes very little.
