The two rod ends of the induction hardening unit can be heated to the quenching temperature at the same time

Have you ever heard of an induction quenching device for an intermediate frequency electric furnace? Two valves are placed on the inductor of the device, which can be heated to the quenching temperature at the same time between the two rod ends. The device is controlled by the main drive motor, where the axial positioning is controlled by Controlled by electromagnets. Simple valve quenching device for intermediate frequency electric furnace Simple valve quenching device for intermediate frequency electric furnace The diameter of one turn in the middle is slightly smaller than the diameter of the turns at the two ends. A valve is placed at each end of the center line of the inductor, and the valve rod end is located in the center of the inductor. Only about 8mm, so after the inductor is energized, both rod ends are heated to the quenching temperature at the same time. The two V-shaped blocks can be both centered and axially positioned. The two valves are heated with a 6kW high-frequency power supply for 3s. After the valves reach the specified temperature, they are put into the quenching tank below. The quenching medium is generally oil. Due to the large production volume of valves, the automatic valve quenching device has become a very necessary quenching device. Using IGBT super audio frequency transistor power supply 80kHz, 9kW, the rotary table is controlled by the main drive motor, the radial positioning is also controlled by the motor, and the axial positioning is controlled by the electromagnet. 7s。 The heating time can be adjusted within 0.1-9. 95s according to the needs of the process, and the working rhythm is the heating time of 0. 7s. This machine tool adopts computer-controlled lanthanum, and has functions such as parts feeding, heating and cooling, and cooling and feeding. It can set process parameters, and has functions such as display, recording, and printing. Induction hardening device measures Kehua has taken some measures in the design of this machine tool: ① Using a half-ring inductor, whose current flows in addition to the circumferential direction, there is also a longitudinal part, so that the top and bottom of the thread can be heated; ② Positioning by spacing The block straddles the lead screw for scanning and quenching. Since the positioning block is tightly straddling the lead screw, the equal clearance is maintained, and the lead screw is rotated and heated, which can make the heating uniform; ③The deformation limiting roller supporting the lead screw is installed, Reduced bending deformation. Induction hardening device The above is the relevant introduction about the induction hardening device. The device uses a half-ring inductor, which can heat the top and bottom of the thread.
