Abstract
Description
Technical Field
[0001] This utility model relates to the field of quenching equipment technology, and in particular to a quenching equipment for flange forging. Background Technology
[0002] Existing flange forging quenching equipment is mainly used to quench flange forgings. Quenching can significantly improve the strength, hardness, wear resistance and fatigue resistance of flange forgings. For example, in some high-pressure and high-temperature pipeline connections, flanges that have been quenched can withstand greater pressure and stress, ensuring the safe and stable operation of the pipeline system.
[0003] However, during its use, it cannot effectively clean the metal shavings formed by the detached oxide scale. These shavings may re-adhere to the surface of the flange forging, causing defects such as pits, bumps or unevenness on the surface, reducing the surface smoothness and precision of the flange forging. Without an effective metal shavings cleaning device, cleaning metal shavings in the quenching fluid requires a lot of time and manpower, and may require draining all the quenching fluid, increasing the complexity and labor intensity of the cleaning work. Summary of the Invention
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a forging and quenching device for flange forgings. During the heating process, the surface of the metal reacts with oxygen in the air to form oxide scale. When entering the quenching stage, due to the rapid temperature change, the adhesion of the oxide scale decreases, causing it to fall off the workpiece and form metal chips. The set blades can stir the quenching liquid inside the quenching box, thereby stirring up the metal chips that have settled in the liquid. After stirring, the metal chips in the quenching liquid can be adsorbed by the magnet through the sleeve, preventing them from re-adhering to the surface of the quenched flange forging or remaining in the quenching liquid and causing turbidity. After quenching, the sleeve can be directly removed from the quenching box, and then the internal magnet can be pulled out, making it easy to clean the metal chips and reducing the difficulty of cleaning the quenching liquid.
[0005] This utility model also provides a flange forging quenching device, comprising: a quenching box, a support frame fixedly connected to the upper surface of the quenching box, a hydraulic rod fixedly connected to the lower surface of the support frame, a lifting plate fixedly connected to the lower end of the hydraulic rod, a connecting rod fixedly connected to the lower surface of the lifting plate, a placement plate fixedly connected to the lower end of the connecting rod, a flange sleeve rod fixedly connected to the upper surface of the placement plate, a paddle rotatably connected to the inner surface of the quenching box, a through hole provided on the quenching box, a sleeve movably connected to the inner surface of the through hole, the sleeve being located inside the quenching box, a magnet movably connected to the inner surface of the sleeve, a support plate fixedly connected to the side surface of the sleeve, and the support plate movably connected to the upper surface of the quenching box.
[0006] According to the present invention, a flange forging and quenching device is provided, wherein a hydraulic cylinder is fixedly connected to the upper surface of the support frame, and the hydraulic rod is driven by the hydraulic cylinder.
[0007] According to the present invention, a flange forging quenching device is provided, wherein a motor is fixedly connected to the lower surface of the quenching box, and the blade is driven by the motor.
[0008] According to the present invention, a flange forging and quenching device is provided, wherein a frame is connected through the side surface of the quenching box, and a viewing window is fixedly connected to the inner surface of the frame.
[0009] According to the present invention, a flange forging quenching device is provided, wherein a support leg is fixedly connected to the lower surface of the quenching box, and a reinforcing rod is fixedly connected to the side surface of the support leg.
[0010] According to the present invention, a flange forging and quenching device is provided, wherein a rotating shaft is rotatably connected to the lower surface of the support leg, and a bracket is fixedly connected to the side surface of the rotating shaft.
[0011] According to the present invention, a flange forging and quenching device is provided, wherein a rotating wheel is rotatably connected to the inner surface of the support, and an anti-slip pad is fixedly connected to the outer surface of the rotating wheel.
[0012] According to the present invention, a flange forging and quenching device is provided, wherein a handle is fixedly connected to the upper surface of the support plate and the magnet, and a protective sleeve is fixedly connected to the outer surface of the handle.
[0013] Compared with existing technologies, this flange forging quenching device utilizes a novel approach. During the heating process, the metal surface reacts with oxygen in the air to form oxide scale. When entering the quenching stage, the rapid temperature change causes the oxide scale to lose adhesion and detach from the workpiece, forming metal debris. The impeller agitates the quenching liquid inside the quenching chamber, stirring up the settled metal debris. After stirring, a magnet can adsorb the metal debris in the quenching liquid through the casing, preventing it from re-adhering to the quenched flange forging surface or causing turbidity in the quenching liquid. After quenching, the casing can be directly removed from the quenching chamber, and the internal magnet can be extracted for easy cleaning of the metal debris, reducing the difficulty of cleaning the quenching liquid.

[0022] Reference Figure 1-4 This utility model discloses a flange forging quenching device, comprising: a quenching box 4, a frame 11 extending through the side surface of the quenching box 4, a viewing window 12 fixedly connected to the inner surface of the frame 11, a support leg 13 fixedly connected to the lower surface of the quenching box 4, a reinforcing rod 14 fixedly connected to the side surface of the support leg 13, a rotating shaft 15 rotatably connected to the lower surface of the support leg 13, a bracket 16 fixedly connected to the side surface of the rotating shaft 15, a rotating wheel 5 rotatably connected to the inner surface of the bracket 16, an anti-slip pad 6 fixedly connected to the outer surface of the rotating wheel 5, a support frame 9 fixedly connected to the upper surface of the quenching box 4, a hydraulic rod 8 fixedly connected to the lower surface of the support frame 9, a hydraulic cylinder 7 fixedly connected to the upper surface of the support frame 9, the hydraulic rod 8 being driven by the hydraulic cylinder 7, a lifting plate 1 fixedly connected to the lower end of the hydraulic rod 8, a connecting rod 2 fixedly connected to the lower surface of the lifting plate 1, a placement plate 3 fixedly connected to the lower end of the connecting rod 2, and a flange sleeve rod 10 fixedly connected to the upper surface of the placement plate 3.
[0023] Specifically: Start hydraulic cylinder 7, which drives hydraulic rod 8 to retract upwards. Hydraulic rod 8 drives lifting plate 1 to rise. Lifting plate 1, through connecting rod 2, raises placement plate 3 to a suitable height. Place the flange forging to be quenched onto flange sleeve rod 10 on placement plate 3 to secure the flange forging. Start hydraulic cylinder 7 again, causing hydraulic rod 8 to extend downwards, which in turn lowers lifting plate 1, connecting rod 2, placement plate 3, and flange forging on flange sleeve rod 10 together. Immerse the flange forging into the quenching liquid in quenching box 4 to begin quenching treatment.
[0024] A blade 24 is rotatably connected to the inner surface of the quenching box 4, and a motor 23 is fixedly connected to the lower surface of the quenching box 4. The blade 24 is driven by the motor 23.
[0025] Specifically: During the quenching process, the oxide scale on the surface of the flange forging falls off due to the rapid temperature change, forming metal debris that settles in the quenching liquid. At this time, the motor 23 is started, and the motor 23 drives the paddle 24 connected to the inner surface of the quenching box 4 to rotate. The paddle 24 stirs the quenching liquid, stirring up the settled metal debris and suspending it in the quenching liquid.
[0026] The quenching box 4 is provided with a through hole 20. A sleeve 21 is movably connected to the inner surface of the through hole 20. The sleeve 21 is located inside the quenching box 4. A magnet 22 is movably connected to the inner surface of the sleeve 21. A support plate 19 is fixedly connected to the side surface of the sleeve 21. The support plate 19 is movably connected to the upper surface of the quenching box 4. A handle 18 is fixedly connected to the upper surface of both the support plate 19 and the magnet 22. A protective sleeve 17 is fixedly connected to the outer surface of the handle 18.
[0027] Specifically: The magnet 22 is used to attract metal shavings suspended in the quenching liquid through the sleeve 21. The sleeve 21 is installed on the quenching box 4 through the through hole 20. The support plate 19 is movably connected to the upper surface of the quenching box 4, which serves to support and fix the sleeve 21. After quenching, the operator holds the protective sleeve 17 on the handle 18 and takes the sleeve 21 out of the quenching box 4. Then, the magnet 22 inside the sleeve 21 is pulled out. The metal shavings that have lost their magnetic attraction will fall off the sleeve 21, so the metal shavings can be easily cleaned.
[0028] Working principle: During operation, hydraulic cylinder 7 is activated, causing hydraulic rod 8 to retract upwards. Hydraulic rod 8 then raises lifting plate 1, which, via connecting rod 2, raises placement plate 3 to a suitable height. The flange forging to be quenched is then placed onto flange sleeve rod 10 on placement plate 3, securing the flange forging. Hydraulic cylinder 7 is activated again, causing hydraulic rod 8 to extend downwards, lowering lifting plate 1, connecting rod 2, placement plate 3, and the flange forging on flange sleeve rod 10 together. The flange forging is then immersed in the quenching liquid in quenching chamber 4, initiating the quenching process. During quenching, the oxide scale on the surface of the flange forging detaches due to the rapid temperature change, forming metal fragments that settle in the quenching liquid. At this point, motor 23 is activated. The motor 23 drives the paddle 24, which is connected to the inner surface of the quenching box 4, to rotate. The paddle 24 stirs the quenching liquid, stirring up the precipitated metal debris and suspending it in the quenching liquid. Using the magnet 22, the metal debris suspended in the quenching liquid is attracted through the sleeve 21. The sleeve 21 is installed on the quenching box 4 through the through hole 20. The support plate 19 is movably connected to the upper surface of the quenching box 4, which serves to support and fix the sleeve 21. After quenching is completed, the operator holds the protective sleeve 17 on the handle 18 and takes the sleeve 21 out of the quenching box 4. Then, the magnet 22 inside the sleeve 21 is pulled out. The metal debris that loses its magnetic attraction will fall off the sleeve 21, so the metal debris can be easily cleaned.
