[0049] A method for using a rotary water jet quenching device for quenching large cylindrical forgings, comprising the following steps:

[0050] Step 1: First, power is connected to the motor and electrical components of the device, then the water supply pipe 20 and the second water pipe 28 are connected to the water source and the lifting pump, and the telescopic pipe and the connecting pipe of the steam absorption joint 24 are connected to the suction pump. Then the second transmission mechanism is started, so that the second transmission motor drives the water spray quenching column 4 to rotate horizontally as a whole, and the brush cleaning mechanism 10 at the side end of the water spray quenching column 4 is driven to extend and retract through the electric telescopic rod, and cooperates with the rotating water spray quenching column 4 to clean the surface of the workbench 1 to prevent the powder impurities on the workbench 1 from causing the cylindrical forgings to slip during quenching. The arrangement of the water spray quenching column 4, the water spray quenching cylinder 2 and the cylinder cover 3 can spray quench all surfaces of the cylindrical forgings more comprehensively and simultaneously, thereby improving the stability of the quenching quality.

[0051] Step 2, then start the first motor 16, so that the first motor 16 drives the barrel cover 3 to rotate and open, then adjust the limit nut 21 on the limit mechanism according to the length of the barrel forging, and adjust the extension length of the first brushing mechanism 8 and the second brushing mechanism 9, then hang the barrel forging into the water spray quenching barrel 2, then start the first motor 16 to drive the barrel cover 3 to rotate and close, then start the booster pump at the water source, so that the water enters the device and starts to spray, the water spray interface on the barrel cover 3 sprays water to the upper end of the barrel forging, the water spray interface on the water spray quenching frame 25 sprays water to the inner wall of the barrel forging, and the water spray interface on the fixed barrel and the sliding barrel of the water spray quenching barrel 2 sprays water to the outer wall of the barrel forging. The first brushing mechanism 8 can better clean and scrape the oxide layer on the surface of the barrel forging to prevent the oxide layer from cooling and adhering to the barrel forging, and at the same time start the first transmission mechanism 7.

[0052] Step 3, when the first transmission motor drives the first transmission gear to rotate, since the first transmission gear is meshed with a circle of teeth on the outside of the tooth groove transmission block 14, and the tooth groove transmission block 14 is fixed on the workbench 1, the first transmission gear revolves around the tooth groove transmission block 14, thereby driving the water spray quenching cylinder 2 to rotate horizontally as a whole. The horizontally rotating water spray quenching cylinder 2 drives the first brushing mechanism 8 to clean the outer wall of the cylindrical forging to brush off the oxidized debris on the cylindrical forging, and drives the sprayed water to rotate and spray on the outer wall of the cylindrical forging, so that the water is evenly sprayed on the outer wall of the cylindrical forging for quenching. The setting of the first transmission mechanism 7 can better drive the water spray quenching cylinder 2 to rotate horizontally, so that the water sprayed from the water spray interface rotates and sprays on the cylindrical forging, thereby improving the stability of water spray quenching. The setting of the fixed cylinder and the sliding cylinder can better match the cylindrical forgings of different lengths, and effectively and comprehensively spray quench the cylindrical forgings.

[0053] Step 4, at the same time, the second transmission motor on the second transmission mechanism starts to rotate. When the second transmission motor drives the second transmission gear to rotate, the second transmission gear is meshed with the transmission ring gear 12, thereby driving the transmission ring gear 12 to rotate, and the transmission ring gear 12 drives the water spray quenching column 4 to rotate horizontally. The horizontally rotating water spray quenching column 4 drives the second brushing mechanism 9 to clean the inner wall of the cylindrical forging to brush off the oxidized debris on the cylindrical forging, and drives the sprayed water to rotate and spray on the inner wall of the cylindrical forging. When the water spray quenching column 4 sprays water on the inner wall of the cylindrical forging, the steam absorption joint 24 on the lifting water spray quenching frame 25 guides the high-temperature steam out of the device under the action of the suction pump to prevent the high-temperature steam from affecting the pressure inside the cylindrical forging, so as to reduce the efficiency of water spray quenching.

[0054] Step five, finally, the quenching of the cylindrical forgings is completed. At this time, the first motor 16 is started again to open the cylinder cover 3, and then the quenched cylindrical forgings are lifted off the device, and then the water supply is disconnected. The sliding cylinder will actively retract without the lifting effect of water pressure, and then the second transmission mechanism and the brush cleaning mechanism 10 are started again, so that the electric telescopic rod drives the cleaning brush block 35 to extend and retract, and cooperates with the rotating water spray quenching column 4 and the water spray quenching frame 25 to clean the supporting surface of the workbench 1, and then the power supply and the suction pump are disconnected, and then the filter collection box 11 is removed, the impurities in the filter collection box 11 are poured out and reinstalled, and the use of the water spray quenching equipment is completed.

[0055] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
