[0021] The implementation principle of a quenching device for metal round bars in an embodiment of the present invention is as follows: first, the metal round bar to be quenched is passed through the clamping hole 39 on the lifting plate 3, and the corresponding electric telescopic rod 41 is started to drive the clamping block 43 to move in the clamping hole 39 to clamp and fix the metal round bar. After clamping, the motor 5 on the quenching box 1 is started to drive the screw 6 to rotate. The lifting plate 3 drives the metal round bar to move downward into the quenching box 1 on the rotating screw 6 for quenching, and drives the flip plate 8 and the filter plate 9 at the bottom end of the lifting frame 4 to move downward in the quenching box 1 as a whole. At the same time, one end of the first insertion rod 13 is used to slide downward in the guide groove 15 to drive the first slide bar 12 to slide in the first slide groove 11, and the flip plate 8 is driven to rotate through the first gear 14, so that the two The flip plate 8 is turned flat and pressed against the quenching box 1 until it moves, and then the flat flip plate 8 moves down with the lifting plate 3 into the cooling water in the quenching box 1, and the metal round bar is inserted into the cooling water for quenching. The filter plate 9 can be used to filter the oxides and dirt generated during the quenching of the metal round bar, so that the oxides and dirt generated during the quenching of the metal round bar are accumulated on the filter plate 9. At the same time, the downward movement of the lifting plate 3 also drives one end of the first insertion rod 13 to move downward against the guide plate 54. When one end of the first insertion rod 13 slides downward against the upper inclined surface of the guide block 55, it pushes the moving frame 46 to drive the slide plate 45 to slide in the fourth slide groove 44, and the second spring 51 is deformed. When one end of the first insertion rod 13 is separated from the guide block 55, the second spring is used to release the second spring. The elastic force of 51 drives the movable frame 46 to reset in the reverse direction, thereby driving the knocking block 49 to knock on the metal round rod, and utilizing the vibration generated during the knocking process to shake off the oxides and dirt generated during the quenching process of the metal round rod, so as to better clean the metal round rod. After quenching, the motor 5 drives the screw 6 to rotate in the reverse direction, and the lifting plate 3 drives the quenched metal round rod to move upward. When the filter plate 9 is removed from the cooling water in the quenching box 1 and moves to the discharge port 56, the first end of the first insertion rod 13 is used to slide upward in the guide groove 15, driving the first slide bar 12 to slide in the first slide groove 11, and rotating the flip plate 8 and the filter plate 9 as a whole through the first gear 14, thereby pouring the filtered oxides and dirt from the discharge port 56 into the collection box 16 for convenient collection. The second gear 24 is driven by the roller 24 on the L-shaped bar 25 to rotate, so that the cleaning barrel 23 and the brush can better push the debris filtered on the filter plate 9 to the collection box 16 for collection, thereby ensuring the cleanliness of the quenching box 1 and the cooling water. Finally, the metal round bar is released.Remove the quenched metal rod from the clamping hole 39.
