They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, this utility model discloses a high-frequency quenching device for toothed plates, including a water tank 1. The bottom and upper part of the water tank 1 are respectively provided with multiple water outlet pipes and water inlet pipes. The water in the water tank 1 is discharged from the bottom water outlet pipe, and the cooling water enters from the water inlet pipe.

[0032] The water tank 1 is equipped with a liftable base 6. The top of the base 6 is equipped with a mold base 5 that supports the toothed plate. The toothed plate has a rectangular outline, and the mold base 5 is also rectangular in shape corresponding to the toothed plate. The top of the mold base 5 is equipped with a mold groove, the structure of which corresponds to the shape of the bottom of the toothed plate.

[0033] The bottom of both ends of the base 6 is provided with vertically arranged support blocks 8. The support blocks 8 are located near the inner wall of the water tank 1. The side wall of the support block 8 near the inner wall of the water tank 1 is provided with cylindrical upper guide rod 10 and lower guide rod 9. The upper guide rod 10 and lower guide rod 9 are both arranged horizontally perpendicular to the support block 8, and the lower guide rod 9 is located directly below the upper guide rod 10.

[0034] A slide rail 12 is provided on the inner wall of the water tank 1 at a corresponding position, which slides in cooperation with the upper guide rod 10 and the lower guide rod 9. The upper section of the slide rail 12 is vertically arranged on the inner wall of the water tank 1, and the lower section of the slide rail 12 is inclinedly arranged on the inner wall of the water tank 1. A push-pull ring 11 is rotatably sleeved on the upper guide rod 10 outside the slide rail 12. A vertically arranged cylinder 4 is provided on the inner wall of the water tank 1 above the push-pull ring 11, and the piston rod of the cylinder 4 is connected to the push-pull ring 11.

[0035] Cylinder 4 drives the push-pull ring 11 to descend, which in turn drives the upper guide rod 10 to descend within the slide rail 12. The lower guide rod 9 also descends within the slide rail 12, and the support block 8 slides vertically downwards. When the lower guide rod 9 slides into the lower section of the slide rail 12, which is inclined, it slides in the direction of inclination of the lower section of the slide rail 12. At this time, the upper guide rod 10 rotates within the slide rail 12 and the push-pull ring 11, and the support block 8 swings accordingly. The mold base 5 at the top of the support block 8 tilts in the opposite direction to the inclination of the lower guide rod 9. The sliding range of the upper guide rod 10 is within the upper section of the slide rail 12. When cylinder 4 drives the push-pull ring 11 to rise, the upper guide rod 10 rises within the slide rail 12, and the lower guide rod 9 slides upwards within the lower section of the slide rail 12 until it enters the upper section and also rises vertically. During this process, the support block 8 gradually straightens until it is in a vertical state.

[0036] The position of the connection between the upper and lower sections of the slide rail 12 corresponds to the liquid level inside the water tank 1. When the lower guide rod 9 slides to the connection between the upper and lower sections of the slide rail 12, the mold base 5 and the toothed plate on the mold base 5 are completely below the liquid level inside the water tank 1. That is, after the mold base 5 and the toothed plate enter the water, the support block 8 swings.

[0037] The side of the water tank 1 is provided with a conveyor belt 2, which conveys toothed plates. Above the conveyor belt 2 is a pneumatic gripper 3 that can move in three directions. The pneumatic gripper 3 can hold the toothed plates on the conveyor belt 2 and put the toothed plates into the mold base 5.

[0038] The upper part of the water tank 1 is equipped with an induction heating device, which includes an induction coil 7. The arrangement trajectory of the induction coil 7 is adapted to the contour of the toothed plate. The induction coil 7 is located on the vertical lifting trajectory of the mold base 5. The induction heating device is existing technology, and its high-frequency power supply, transformer and capacitor structure will not be described in detail here.

[0039] A slide plate 13 is provided inside the water tank 1 on the side of the slide rail 12. The slide plate 13 is located on the side opposite to the inclination direction of the lower section of the slide rail 12. The slide plate 13 is arranged at an angle, with its lower end hinged to the inner wall of the water tank 1 and its higher end located on the side of the slide rail 12. An elastic element is provided at the bottom of the higher end of the slide plate 13, and the elastic element is connected to the bottom of the water tank 1. In this embodiment, the elastic element is an air bladder 14, but it can also be a spring. An elastic pad 15 is provided on the inner wall of the water tank 1 at the lower end of the slide plate 13. The elastic pad 15 is made of rubber or other elastic materials.

[0040] Conveyor belt 2 transports the toothed plate to the side of water tank 1. Pneumatic gripper 3 clamps the toothed plate above induction coil 7. During this process, cylinder 4 drives upper guide rod 10 to slide upward, and support block 8 slides upward, positioning mold base 5 above induction coil 7. Pneumatic gripper 3 places the toothed plate into the mold groove of mold base 5. After pneumatic gripper 3 disengages from toothed plate, cylinder 4 drives upper guide rod 10 to slide downward, and support block 8 and mold base 5 slide downward accordingly, causing toothed plate to vertically downward into the inside of induction coil 7. High-frequency AC current is input into induction coil 7, and toothed plate rapidly heats up. Cylinder 4 then drives support block 8 to slide downward, and support block 8 drives mold base 5 and toothed plate to slide vertically away from the inside of induction coil 7 and into the water in water tank 1. Toothed plate rapidly cools down. As support block 8 continues to slide downward, lower guide rod 9 slides into the lower section of slide rail 12. The support block 8 swings towards the slide plate 13. As the swing amplitude of the slider increases, the toothed plate on the mold base 5 detaches and falls onto the slide plate 13. The toothed plate slides on the slide plate 13 towards the lower end of the slide plate 13. When the toothed plate falls onto the slide plate 13, the elastic element achieves the purpose of buffering. When the toothed plate slides to the lower end of the slide plate 13, the toothed plate contacts the elastic pad 15 on the inner wall of the water tank 1. The elastic pad 15 also has a certain buffering effect, avoiding rigid impact between the toothed plate and the inner wall of the water tank 1. Subsequently, the toothed plate can be manually clamped out of the water tank 1.

[0041] This utility model automatically conveys and clamps the toothed plate onto the mold base 5. After the mold base 5 descends, it automatically undergoes high-frequency quenching and then continues to descend, allowing the toothed plate to enter the water for cooling. During the descent of the mold base 5 into the water, it swings with the cooperation of the slide rail 12, automatically tilting the toothed plate so that it falls onto the slide plate 13 and finally waits to be clamped and transferred. Compared with traditional manual operation, the degree of automation is improved, the work efficiency is greatly improved, and the number of manual operation steps is reduced, thus improving safety.

[0042] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
