[0002] A metal heat treatment process that heats a metal workpiece to a certain appropriate temperature and maintains it for a period of time, and then immerses it in a quenching medium for rapid cooling. Common quenching media include salt water, water, mineral oil, air, etc. Quenching can improve the hardness and wear resistance of metal workpieces, so it is widely used in various tools, molds, gauges and parts that require surface wear resistance.

[0003] Water-cooling quenching is the most commonly used method for machine tools, which directly affects the quality of semi-finished metals. In the past, the water-cooling mechanism on the working head of the quenching machine tool was relatively simple and had low applicability. The quenching degree of parts of different sizes was different. Therefore, a new water-cooling mechanism was needed to be able to handle the quenching degree of parts within a certain range and improve the quality and efficiency of parts after quenching and water cooling. At the same time, this water-cooling mechanism can also have the characteristics of adjustability to cope with different quenching parts. Utility Model Content

[0025] As shown in the figure, a water cooling mechanism of a quenching machine tool is composed of a water cooling working valve and adjustable connecting parts.

[0026] The main water-cooling working valve 20 is vertically connected to the shaft 5. The inner ring surface of the main water-cooling working valve 20 has 20 water outlet holes 1 evenly distributed. The water outlet holes 1 are connected to the water pipe 2 inside the water outlet valve, and the water pipe 2 is connected to the external main water pipe 9. The main water-cooling working valve has secondary water-cooling outlet valves 19 and 21 on the upper and lower sides. The secondary water-cooling outlet valve 19 is parallel to the main water-cooling working valve 20. The inner ring surface of the secondary water-cooling working valve 19 has 20 first semicircular water outlet holes 3 evenly distributed. The inner ring surface of the secondary water-cooling working valve 21 has 20 second semicircular water outlet holes 10 evenly distributed. The secondary water-cooling working valves 19 and 21 are fixedly connected to the connecting member 4. The connecting member 4 is slidingly connected to the shaft 5 with clearance fit. The movable screw 7 is installed on the right side of the connecting member 4 and connected to the slide groove 8.

[0027] The shaft 5 is provided with a groove plane 8, the groove plane 8 is tangent to the threaded screw 7, and there is a scale 6 on the groove plane 8 and the empty space above the connecting member 4. The connection between the connecting member 4 and the shaft 5 has another symmetrical set with the main water-cooled working valve 20.

[0028] When in use, workers first fine-tune and debug the mechanism according to the size of the parts to be quenched, and adjust the water flow direction and flow rate to the best state. First adjust the screw 7 on the shaft to adjust the water flow rate. There is a scale 6 in the space between the connector 4 and the shaft 5. There are three options, one is to close the secondary water-cooled working valve 11, one is a small water volume 12, and the other is a large water volume 13, which is controlled by moving up and down and fixing the position of the connector 4. Then adjust the water flow direction of the water-cooled working valve, which is achieved by toggling the connecting rod 16 of the secondary working valve. The connecting rod 16 is connected to a semi-circular connecting plate 15. Toggling one will drive all the water outlets 17 to rotate. The connecting rod 16 has a gear position, which can be fixed by toggling into the gear position 22. Water for water cooling is sucked from the cooling box into the water inlet pipe 7 in the main shaft 5 through the main pipe 9, and enters the working valve in three lines. The water flows through the pipe 2 in the working valve and then through the adjusted water outlet to work.

[0029] Implementation Case 1: Close the secondary working valves 19 and 21, adjust the connector 4 to the lowest position through the screw 7, and the water flow from the main pipe 9 into the inner water pipe 8 of the shaft is blocked by the solid block inside the connector 4 and cannot enter the secondary working valve, thereby closing the secondary working valve.

[0030] Implementation Case 2: To reduce the water flow rate of the secondary working valve, adjust the connector 4 to the middle position according to the scale 6 through the screw 7. The water flowing from the main pipe 9 into the inner water pipe 8 flows into the small-diameter inlet 12 in the connector 4 and enters the secondary working valve pipeline 2, blocking part of the water flow and reducing the water pressure in the working valve, thereby controlling and reducing the water flow rate.

[0031] Implementation Case 3: Normal water flow rate of the secondary working valve, adjust the connecting piece 4 to the uppermost gear position through the screw 7 according to the scale 6, and the water flowing from the main pipe 9 into the water pipe 8 in the shaft flows into the inlet 13 of the connecting piece 4 with the same diameter as the water outlet in the shaft, and enters the secondary working valve pipeline 2 without blocking any water flowing in from the main pipe 9. When a large amount of water flows in, the water pressure in the working valve pipeline 2 increases, thereby increasing the water flow rate.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
