Technical Field

[0001] The present invention relates to the technical field of quenching processing, and specifically to a vacuum quenching oil adding device. Background Art

[0002] Quenching is a heat treatment process method in which steel is heated to above the critical temperature, held for a certain time, and then cooled at a rate greater than the critical cooling rate to obtain an unbalanced structure mainly composed of martensite. Quenching is the most widely used process method in the steel heat treatment process. When the existing vacuum quenching device cools the workpiece to be quenched, the workpiece is directly immersed in the quenching medium for natural cooling.

[0003] According to the patent (CN216192519U), a vacuum quenching oil adding device includes a quenching and washing tank. A support frame is fixed to the top of the quenching and washing tank. A liquid storage tank is fixed to the top of the support frame. A liquid inlet pipe is arranged at the top of the liquid storage tank. A liquid outlet pipe is arranged at the bottom of the liquid storage tank. The bottom end of the liquid outlet pipe extends into the quenching and washing tank and is equipped with a spray head. A diversion mechanism is arranged inside the liquid storage tank. Two rotating shafts are rotatably connected to one side side wall of the quenching and washing tank. One end of each rotating shaft is fixed with a spiral fan blade. Two mutually meshing gears are rotatably connected to one side outer wall of the quenching and washing tank. The two gears are respectively coaxially arranged with the two spiral fan blades. A driving motor is installed at the bottom of the quenching and washing tank. The output shaft of the driving motor is fixed to one of the rotating shafts through a coupling. The diversion mechanism includes a rotating rod rotatably connected to one side side wall of the liquid storage tank. One end of the rotating rod is fixed with a turntable. A fixed rod is fixed to one side side wall of the turntable. A sliding frame is fixed to one side inner wall of the liquid storage tank.

A connecting rod is hinged between the top end of the lifting rod and the fixed rod. A first pulley is rotatably connected to one side outer wall of the liquid storage tank.

[0004] Currently, although the existing quenching oil adding equipment can add quenching oil in batches, there are still some deficiencies. For example, during the adding process, it is inconvenient to treat the aging products that are insoluble in oil and deposited at the bottom of the quenching oil tank, which will affect the cooling effect of the workpiece. Moreover, although the continuously added quenching oil can ensure the cleanliness of the oil liquid, it will cause the overflow of the oil liquid, making it inconvenient to perform the cyclic adding operation of the quenching oil, thereby affecting the processing efficiency of the workpiece. Summary of the Invention

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0038] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0039] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an apparatus for adding vacuum quenching oil, including a quenching oil tank 1, the quenching oil tank 1 is fixedly installed above the base 6, a slope 13 is provided at the lower end of the inner cavity of the quenching oil tank 1, and the slopes 13 are symmetrically arranged. A treatment assembly is provided at the lower end of one side of the quenching oil tank 1, a circulation assembly is provided at the upper end of the treatment assembly, and an oil storage tank 15 is provided at the upper end of one side of the quenching oil tank 1;

[0040] The processing component includes a box body 2, a servo motor 21, a lead screw 22, a driving gear 23, a fixed net 24, a limiting rod 25, a piston plate 26 and a lead screw 22 sleeve. The box body 2 is arranged at the lower end of one side of the quenching oil tank 1. The lower end of the box body 2 is fixedly connected to the upper end of one side of the base 6. A servo motor 21 is arranged on one side of the box body 2. The output end of the servo motor 21 is equipped with a lead screw 22. The other end of the lead screw 22 is fixedly installed with a driving gear 23. The other side of the inner cavity of the box body 2 is detachably installed with a fixed net 24. One side of the fixed net 24 is provided with a piston plate 26;

[0041] The circulation component includes a first channel 3, a first one-way valve 31, a second channel 32 and a second one-way valve 33. The lower end of the other side of the box body 2 communicates with the first channel 3. The upper end of the box body 2 communicates with the second channel 32.

[0042] In the present invention, during the addition, first, by turning on the servo motor 21, the servo motor 21 drives the lead screw 22 to rotate. The lead screw 22 cooperates with the lead screw 22 sleeve to drive the piston plate 26 to move to the right. The piston plate 26 slowly moves to the right in the inner cavity of the box body 2. At the same time, a negative pressure will be generated during the movement of the piston plate 26, and then the quenching oil in the quenching oil tank 1 is slowly pumped. Thus, the quenching oil deposited at the bottom of the quenching oil tank 1 is pumped into the box body 2. The residual impurities in the quenching oil pumped into the box body 2 are filtered and intercepted by the filter net. Thus, the aging products that are insoluble in oil in the quenching oil are intercepted on the left side of the box body 2. Furthermore, the aging products that are insoluble in oil and mixed in the quenching oil are processed, reducing the situation that the aging products insoluble in oil deposited at the bottom of the quenching oil tank 1 affect the cooling effect of the workpiece. After the suction is completed, then control the servo motor 21 to reverse. The lead screw 22 cooperates with the lead screw 22 sleeve to drive the piston plate 26 to move to the left. The piston plate 26 squeezes the quenching oil that has been processed and remains in the box body 2. Due to the setting of the first one-way valve 31 and the second one-way valve 33, it is ensured that during the extrusion of the quenching oil, the quenching oil will not flow back into the quenching oil tank 1, and the quenching oil is discharged into the oil storage tank 15. Moreover, the setting of the second one-way valve 33 avoids the situation that the quenching oil in the oil storage tank 15 is discharged into the box body 2 during the suction process. Thus, the operation of circulating and adding the processed quenching oil is realized. At the same time, the one-way suction and discharge circulation operation solves the situation that although the continuously added quenching oil can ensure the cleanliness of the oil, it will cause the oil to overflow. At the same time, during the forward rotation of the lead screw 22, the driving gear 23 on the lead screw 22 will drive the driven gear 5 to rotate accordingly. Then, the driven gear 5 drives the auger rod 4 to rotate. Combined with the slope 13 arranged in the quenching oil tank 1, the auger rod 4 can convey the aging products that are insoluble in oil and deposited at the bottom of the quenching oil tank 1. Thus, the processing efficiency of the quenching oil is improved. Then, combined with the oil pump 14 and the nozzle 12, the quenching oil is circulated and added above the quenching oil tank 1.

[0046] It should be noted that, through the setting of the auger rod 4, the auger rod 4 can be driven to rotate in conjunction with the rotation of the screw rod 22, thereby assisting the transportation of aging products insoluble in the quenching oil, thereby improving the treatment effect of aging products insoluble in the quenching oil.
