The screw 9 and the nut 10 convert the rotary motion into linear motion. In order to limit the overturning and swing of the quenching table 2, a guide sleeve 11 is fixed on both sides of the nut 10 and the inner wall of the quenching tank 1, and a guide rail 12 is installed on the quenching table 2. , The guide rail 12 and the guide sleeve 11 limit the quenching table 2 to only move in one direction; the moving position of the quenching table 2 is controlled by the number of turns of the power motor 8 and the position of the quenching table 2 in the quenching tank 1 and the up and down reciprocating The moving speed is precisely adjusted. During the up and down movement of the quenching table 2, the workpiece 28 and the cooling medium will move quickly. The cooling medium is used to eliminate the steam around the workpiece 28, so that the steam diffuses quickly and the workpiece 28 is cooled evenly. The medium circulation system 4 includes a circulating pump 13, a variable frequency motor 14, a liquid suction line 15, a liquid suction port 16, a liquid discharge line 17, an electronic flow meter 18, a cooler 19, an electric regulating valve 20 and a flow controller 21, The inlet of the circulating pump 13 is connected with the liquid suction pipe 15, and the outlet of the circulating pump 13 is connected with the liquid outlet pipe 17. The liquid suction pipe 15 is arranged on both sides of the upper part of the quenching tank 1 near the tank wall. The pipeline 15 is arranged with 5-50 liquid suction ports 16 arranged along the axis of the suction pipe, which can suck the higher temperature cooling medium more uniformly; the liquid outlet pipeline 17 is vertically downward in the middle of the right side wall of the quenching tank 1 After reaching the bottom of the rear tank, it extends to the left and communicates with the medium outlet system 5; an electric regulating valve 20 and an electronic flow meter 18 are installed on the liquid outlet pipe 17, and the electronic flow meter 18 measures and displays the flow rate of the cooling medium. At the same time, the electronic flowmeter 18 converts the medium flow into a signal, and then transmits it to the flow controller 21. The flow controller 21 adjusts the output signal to control the frequency of the variable frequency motor 14, and the circulating pump 13 pumps the low-temperature cooling medium into the liquid outlet pipe 17. , The flow controller 21 controls the opening size of the electric regulating valve 20 at the same time, thereby controlling the flow of the circulating pump 13; a cooler 19 is provided on the liquid outlet pipe 17 to communicate The superheat exchange controls the temperature of the cooling medium; the medium outlet system 5 includes a medium outlet 22, a baffle 23 and a surrounding plate 25, which is arranged under the quenching table 2 in the quenching tank 1 to control the flow direction of the quenching medium; the baffle 23 Composed of 1-100 blades 24, each blade 24 has a different length. According to the flow direction of the cooling medium, the length of the blades 24 is arranged in order from small to large, and the resistance to the cooling medium is different, so that the cooling medium flows out of the medium outlet more uniformly 22. Flow to the quenching table 2; the deflector 23 can adjust the angle according to the needs to control the flow of the quenching medium. The deflector 23 is adjusted in the horizontal direction, which can reduce the width of the cooling medium outlet 22, and the cooling medium presents a turbulent flow state. Decrease, the pressure increases, the hot and cold media can be mixed more fully, the deflector 23 is adjusted in the vertical direction, which can increase the width of the cooling medium outlet 22, the cooling medium flow rate increases, the pressure decreases, and the cooling capacity improves; An enclosure 25 is arranged around the upper part of the outlet 22 and the lower part of the quenching table 2. The enclosure 25 allows the cooling medium to diffuse outward from the upper part of the workpiece 28, prevents the cooling medium from spreading, and effectively improves the cooling capacity of the cooling medium; medium blowing system 6 Installed above the roller between the quenching table 2 and the circulating pump 13, the medium blowing system 6 includes a fan 26 and a wind hood 27. The wind hood 27 concentrates the wind on the surface of the workpiece 28, and the strong wind generated by the fan 26 drives the surface of the workpiece 28 The cooling medium is blown off, and the blown off cooling medium drips into the quenching tank 1, saving the cooling medium and reducing the workload of the subsequent cleaning process.
[0018] When this embodiment is in use, the workpiece 28 is placed in the basket, the material frame is placed on the idler, and the idler is driven to rotate by power, so the basket full of the workpiece 28 can move on the idler, the basket and the workpiece 28 After heating and holding in the heating furnace to a certain temperature and time, move out of the heating and holding zone and move to the cooling zone roller 7. The cooling zone roller 7 stops rotating under external control, and the quenching table lifting system 3 controls the quenching table 2 to descend , The material frame and the workpiece 28 are immersed in the cooling medium along with the quenching table 2. When the quenching table 2 moves up and down, the workpiece 28 and the cooling medium will move quickly. The cooling medium is used to eliminate the steam around the workpiece 28 and make the steam It spreads quickly and the workpiece 28 is cooled evenly. During the cooling process of the workpiece 28, the circulating pump 13 rotates, sucks in the high-temperature cooling medium through the liquid suction pipe 15 and the liquid suction port 16, and heats it through the cooler 19 of the liquid outlet pipe 17. Exchange, the temperature of the high-temperature cooling medium is reduced, and the low-temperature cooling medium flows from the medium outlet 22 to the workpiece 28 to cool the workpiece 28; the workpiece 28 after cooling is lifted by the quenching table lifting system 3, separated from the cooling medium, and reaches the heating furnace In the horizontal position of the supporting roller, the supporting roller rotates to translate the workpiece 28 under the wind hood 27 of the medium blowing system 6. The wind hood 27 concentrates the wind on the surface of the workpiece 28, and the fan 26 blows away the cooling medium on the surface of the workpiece 28. The blown off cooling medium drops into the quenching tank 1, and the work piece 28 that has been blown off is moved to the subsequent station through the rotation of the supporting roller.
