[0011] Furthermore, a first motor is fixedly installed on the outer wall at the bottom of the housing at the position corresponding to the screw, and the output shaft of the first motor is fixedly connected to one end of the screw.

[0012] Furthermore, sliders are symmetrically fixedly installed at both ends of the movable plate, and grooves are provided on both sides of the inner wall of the box corresponding to the slider positions, with the sliders being limited and slidably installed inside the grooves.

[0013] Furthermore, the movable plate is T-shaped, and a fixed box is slidably disposed inside the top of the movable plate. A second motor is fixedly installed inside the fixed box, and the turntable is fixedly installed at the top of the output shaft of the second motor.

[0014] Furthermore, a hydraulic rod is fixedly installed inside the bottom end of the movable plate, and the output rod of the hydraulic rod is fixedly connected to the bottom of the fixed box. The baffle is fixedly installed on the outer side of the bottom of the turntable.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a steel forging tempering processing device, including a box body 1, the box body 1 being T-shaped, with inlets and outlets 4 symmetrically opened on both sides of the box body 1, and a movable platform 2 movably arranged inside the inlets and outlets 4 via an adjustment mechanism, the movable platform 2 including a movable plate 6, a turntable 16 and a baffle 17, the top of the turntable 16 being placed on a forging flange 3, and a tempering mechanism being arranged at the center of the top of the box body 1, the tempering mechanism including a heating chamber 11 and a high-frequency tempering coil 12, the heating chamber 11 having blower mechanisms 5 arranged on both sides corresponding to the top of the box body 1, the blower mechanisms 5 being arranged at the top of the box body 1, so that the movable platform 2 can pass under the blower mechanisms 5 during lateral movement, facilitating air cooling of the forging flange 3 from above, avoiding impact on the surrounding environment and personnel.

[0023] In this embodiment, the heating chamber 11 is located at the center of the top of the housing 1. The high-frequency tempering coil 12 is fixedly installed inside the heating chamber 11. The heating chamber 11 and the moving platform 2 are in the same vertical plane. The blowing mechanism 5 includes a fan 10 and a ventilation chamber 9. The ventilation chamber 9 is symmetrically opened inside the housing 1 on both sides corresponding to the heating chamber 11. The fan 10 is fixedly installed on the top of the ventilation chamber 9. The fan 10 can draw outside air into the ventilation chamber 9, which facilitates the cooling of the forging flange 3 by blowing air through the ventilation chamber 9. The heating chamber 11 and the high-frequency tempering coil 12 facilitate the heating and tempering of the forging flange 3.

[0024] In this embodiment, the adjusting mechanism includes a screw 7, which is rotatably installed inside the bottom of the housing 1. The bottom of the moving plate 6 is screwed onto the screw 7 through a screw hole. A first motor 8 is fixedly installed on the outer wall of the bottom of the housing 1 at the position corresponding to the screw 7. The output shaft of the first motor 8 is fixedly connected to one end of the screw 7. The first motor 8 drives the screw 7 to rotate inside the housing 1, which facilitates the lateral movement of the forging flange 3 through the screwing action of the screw 7 and the moving plate 6, and facilitates the subsequent heating, tempering and blowing of the forging flange 3.

[0025] In this embodiment, sliders are symmetrically fixedly installed at both ends of the movable plate 6. Slide grooves 13 are formed on both sides of the inner wall of the housing 1 corresponding to the slider positions. The sliders are slidably installed inside the slide grooves 13. The movable plate 6 is T-shaped. A fixed box is slidably installed inside the top of the movable plate 6. A second motor 15 is fixedly installed inside the fixed box. The turntable 16 is fixedly installed at the top of the output shaft of the second motor 15. A hydraulic rod 14 is fixedly installed inside the bottom of the movable plate 6. The output rod of the hydraulic rod 14 is fixedly connected to the bottom of the fixed box. A baffle 17 is fixedly installed on the bottom of the turntable 16. On the side, the sliding of the slider inside the slide groove 13 can limit the movement of the moving plate 6, thereby improving the stability of the moving plate 6. The second motor 15 can drive the forging flange 3 to rotate through the turntable 16, thereby improving the heating and tempering efficiency of the forging flange 3. The hydraulic rod 14 can adjust the height of the fixed box, the turntable 16 and the forging flange 3, so that the forging flange 3 can enter the interior of the heating chamber 11 or move out of the interior of the heating chamber 11. The baffle 17 can block the bottom of the heating chamber 11 to ensure the internal temperature of the heating chamber 11 and facilitate the tempering heating of the forging flange 3. The first motor 8 and the second motor 15 are both servo motors.

[0026] When using this steel forging tempering device, the forging flange 3 to be tempered is placed on top of the turntable 16. The first motor 8 is started, and the first motor 8 drives the screw 7 to rotate inside the housing 1. The screw 7 screws and drives the moving plate 6 to slide inside the housing 1. The slider and slide groove 13 can limit the movement of the moving plate 6, thereby improving the stability of the moving plate 6. The moving plate 6 and the moving table 2 move the forging flange 3 to the bottom of the heating chamber 11. The first motor 8 is turned off, and the hydraulic rod 14 is started. The hydraulic rod 14 drives the forging flange 3 and the baffle 17 to rise through the fixed box and the turntable 16. The turntable 16 and the forging flange 3 both enter the interior of the heating chamber 11. The baffle 17... 7 is in close contact with the bottom of the heating chamber 11. The second motor 15 is started. The second motor 15 drives the forging flange 3 to rotate through the turntable 16, which facilitates uniform heating of the forging flange 3. After the heating is completed, the forging flange 3 is moved out of the heating chamber 11 by the hydraulic rod 14, the fixed box, and the turntable 16. The forging flange 3 is then moved by the first motor 8, the screw 7, the moving plate 6, etc. The fan 10 is started, which draws outside air into the ventilation chamber 9 to facilitate cooling of the forging flange 3. At this time, the forging flange 3 is still inside the box 1 and will not affect the surrounding environment or personnel, thereby improving the safety of the device and making it highly practical.
