Description

Technical Field

[0001] This application relates to the field of metal heat treatment equipment technology, and in particular to a flange rapid quenching device. Background Technology

[0002] Flanges are common connecting parts between shafts in mechanical equipment. During flange manufacturing, heat treatment is required to alter the flange's mechanical properties, with flange quenching being a key component. Traditional flange quenching often involves manual immersion in quenching fluid, which is inefficient. Currently, the industry needs an automated flange quenching device.

[0003] A related flange quenching device includes a quenching pool and a clamping assembly. The quenching pool is filled with quenching fluid. The clamping assembly clamps the flange into the quenching pool. After the flange is quenched in the quenching pool, it is clamped out of the quenching pool by the clamping assembly.

[0004] However, the existing flange quenching device can only quench one flange at a time, resulting in low quenching efficiency and making it unsuitable for quenching a large number of flanges. Utility Model Content

[0005] To address the issue that flange quenching devices cannot be applied to quenching a large number of flanges, this application provides a rapid flange quenching device.

[0006] This application provides a rapid quenching device for flanges, which adopts the following technical solution:

[0007] A flange rapid quenching device, comprising:

[0008] A fixed housing is fixedly installed on the ground. A liquid injection chamber is provided inside the fixed housing. An inlet and an outlet are provided on the periphery of the fixed housing. The inlet and outlet are respectively connected to the liquid injection chamber.

[0009] The partition is vertically fixed inside the injection chamber. There are four sets of partitions, and the four sets of partitions are parallel to the periphery of the fixed shell.

[0010] The guide plate is inclinedly set in the injection chamber. The upper end of the guide plate is fixedly connected to the upper end of the fixed housing, and the lower end of the guide plate is fixedly connected to the upper end of the partition. The guide plate and the partition correspond one-to-one. Both the guide plate and the partition are provided with liquid passage holes.

[0011] A buffer assembly is rotatably mounted on a partition plate, and the buffer assembly cushions the flanges that slide off the partition plate;

[0012] The conveying assembly is fixedly installed in the liquid injection chamber and conveys the quenched flange out of the liquid injection chamber.

[0013] By adopting the above technical solution, the fixed shell provides installation space for the flange rapid quenching device. Quenching liquid can be injected into the injection chamber through the liquid inlet and discharged through the liquid outlet. The guide plate allows the flange entering the flange rapid quenching device to slide along the guide plate onto the buffer assembly. The buffer assembly can buffer the flange entering the injection chamber and allow the flange to slide onto the conveying assembly, reducing the collision intensity of the flange onto the conveying assembly. The partition can restrict the movement space of the flange in the injection chamber and increase the probability of the flange sliding onto the conveying assembly. The conveying assembly can convey the flange that has been quenched in the quenching liquid to the outside of the injection chamber. The conveying assembly can continuously convey the quenched flange, improving the quenching efficiency of the flange.

[0014] Optionally, the buffer component includes:

[0015] Telescopic plate, the fixed end of the telescopic plate is rotatably connected to the partition plate;

[0016] A connecting rod is vertically and fixedly installed inside the injection chamber.

[0017] A connecting block is fitted onto a connecting rod, the connecting rod and the connecting block are slidably connected, and the connecting block is rotatably connected to the telescopic end of the telescopic plate.

[0018] A spring is fitted onto the connecting rod. One end of the spring is fixedly connected to the lower end of the connecting block, and the other end of the spring is fixedly connected to the bottom of the injection chamber.

[0019] By adopting the above technical solution, the flange that slides down the guide plate falls onto the telescopic plate. Under the influence of the flange's gravity, the telescopic plate tilts from a horizontal state. As the telescopic end of the telescopic plate extends, it drives the connecting block to move downward along the axis of the connecting rod. The movement of the connecting block compresses the spring, which in turn buffers the connecting block and the flange. When the flange detaches from the telescopic end of the telescopic plate, the connecting block moves upward along the axis of the connecting rod under the elastic force of the spring, thereby causing the telescopic end of the telescopic plate to shorten and return to a horizontal state, facilitating the next buffering operation.

[0020] Optionally, the transmission component includes:

[0021] The motor is fixedly mounted on a fixed housing, and the output end of the motor passes through the fixed housing.

[0022] The active roller is rotatably mounted on the fixed housing, and one end of the active roller is fixedly connected to the output end of the motor.

[0023] The driven roller is rotatably mounted on the fixed housing, and both the driven roller and the driving roller are parallel to one side of the fixed housing in the width direction;

[0024] Sprockets are fixedly mounted on the driving roller and the driven roller respectively, with the sprockets on the driving roller and the driven roller being set accordingly;

[0025] The drive chain is wound around two sets of sprockets;

[0026] The transport plate is rotatably mounted on the transmission chain.

[0027] By adopting the above technical solution, the rotation of the motor can drive the active roller to rotate synchronously, the rotation of the active roller can drive the sprocket to rotate synchronously, the rotation of the sprocket can drive the transmission chain and the driven roller to rotate, and the rotation of the transmission chain can drive the transport plate to move along the length of the transmission chain, thereby transferring the flange that falls off the buffer assembly from the liquid injection chamber to the outside of the fixed shell, so as to achieve the purpose of sequentially transferring multiple quenched flanges away from the quenching device.

[0028] Optionally, the height of the inlet is lower than that of the outlet.

[0029] By adopting the above technical solution, the height of the inlet is lower than that of the outlet, which allows sufficient quenching liquid to be pumped into the entire injection chamber, reducing the probability that the quenching liquid will not quench the device and will flow out through the outlet, thus improving the quenching efficiency of the flange rapid quenching device.

[0030] Optionally, a buffer pad is provided around the fixed end of the telescopic plate.

[0031] By adopting the above technical solution, the buffer pad can buffer the flange that slides from the guide plate onto the telescopic plate, reduce the impact intensity of the flange on the telescopic plate, and improve the service life of the telescopic plate.

[0032] Optionally, two sets of sprockets and drive chains are spaced apart along the axis of the drive roller.

[0033] By adopting the above technical solution, the arrangement of two sets of sprockets and transmission chains can improve the transmission stability of the transport plate.

[0034] Optionally, multiple sets of transport plates are spaced apart along the length of the transmission chain.

[0035] By adopting the above technical solution, multiple sets of transport plates can transport multiple quenched flanges sequentially, thereby improving the quenching efficiency of the flange rapid quenching device.

[0036] Optionally, the transport plate may be provided with multiple sets of anti-slip ridges at intervals.

[0037] By adopting the above technical solution, the anti-slip ridges can increase the friction between the transport plate and the flange, thereby improving the conveying capacity of the conveying assembly for the flange.

[0038] Optionally, the transport plate is provided with multiple sets of drainage holes at intervals.

[0039] By adopting the above technical solution, the setting of the drain hole enables the quenching liquid on the transport plate to flow quickly from the transport plate to the injection chamber, reducing the probability of the quenching liquid leaving the injection chamber through the conveying component, thereby reducing the amount of quenching liquid lost and saving the quenching cost of the flange rapid quenching device.

[0040] In summary, the embodiments of the present invention provide a flange rapid quenching device, which includes at least one of the following beneficial technical effects:

[0041] 1. The fixed housing provides installation space for the flange rapid quenching device. Quenching liquid can be injected into the injection chamber through the liquid inlet and discharged through the liquid outlet. The guide plate allows the flange entering the flange rapid quenching device to slide along the guide plate onto the buffer assembly. The buffer assembly can cushion the flange entering the injection chamber and allow the flange to slide onto the conveying assembly, reducing the impact intensity of the flange on the conveying assembly. The partition can limit the movement space of the flange in the injection chamber and increase the probability of the flange sliding onto the conveying assembly. The conveying assembly can transport the flange that has been quenched in the quenching liquid to the outside of the injection chamber. The conveying assembly can continuously transport the quenched flange, improving the quenching efficiency of the flange.

[0042] 2. The rotation of the motor can drive the active roller to rotate synchronously, the rotation of the active roller can drive the sprocket to rotate synchronously, the rotation of the sprocket can drive the transmission chain and the driven roller to rotate, and the rotation of the transmission chain can drive the transport plate to move along the length of the transmission chain, thereby transferring the flange that falls off the buffer assembly from the liquid injection chamber to the outside of the fixed shell, so as to realize the purpose of sequentially transferring multiple quenched flanges away from the quenching device.

[0051] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0052] Combination Figure 1 , Figure 2 and Figure 3 This application discloses a flange rapid quenching device, comprising: a fixed housing 31, a partition 32, a guide plate 33, a buffer assembly 1, and a conveying assembly 2; the fixed housing 31 is fixedly installed on the ground, and a liquid injection chamber 40 is provided inside the fixed housing 31; an inlet 38 and an outlet 39 are provided on the periphery of the fixed housing 31, and the inlet 38 and outlet 39 are respectively connected to the liquid injection chamber 40; the partition 32 is vertically fixedly installed in the liquid injection chamber 40, and four sets of partitions 32 are provided, with the four sets of partitions 32 being flush with the periphery of the fixed housing 31. The guide plate 33 is inclinedly disposed in the injection chamber 40. The upper end of the guide plate 33 is fixedly connected to the upper end of the fixed housing 31, and the lower end of the guide plate 33 is fixedly connected to the upper end of the partition plate 32. The guide plate 33 and the partition plate 32 correspond one-to-one. Both the guide plate 33 and the partition plate 32 are provided with liquid passage holes 41. The buffer assembly 1 is rotatably disposed on the partition plate 32. The buffer assembly 1 buffers the flange that slides off the partition plate 32. The conveying assembly 2 is fixedly disposed in the injection chamber 40. The conveying assembly 2 conveys the quenched flange away from the injection chamber 40.

[0053] In this embodiment, the fixed housing 31 is rectangular, the injection chamber 40 is rectangular, and the partition 32 is rectangular. The partition 32 restricts the movement space of the flange within the injection chamber 40. The guide plate 33 adjacent to the conveying assembly 2 is triangular, while the other guide plates 33 are isosceles trapezoids. The liquid passage hole 41 is cylindrical, allowing the quenching liquid to pass through the partition 32 and guide plates 33, thus filling the injection chamber 40 with quenching liquid. The long side of the guide plate 33 is fixedly connected to the periphery of the fixed housing 31, and the short side of the guide plate 33 is fixedly connected to the upper end of the partition 32. The guide plate 33 is inclined so that the worker can be placed on it. The flange can slide down along the guide plate 33 onto the buffer assembly 1. The buffer assembly 1 can cushion the sliding flange, reduce the impact intensity of the flange on the conveying assembly 2, and improve the service life of the conveying assembly 2. After being buffered by the buffer assembly 1, the flange slides down onto the conveying assembly 2 and is conveyed away from the fixed housing 31 by the conveying assembly 2. The height of the liquid inlet 38 is lower than that of the liquid outlet 39, so that sufficient quenching liquid can be pumped into the entire liquid injection chamber 40. That is, the height of the quenching liquid in the liquid injection chamber 40 is equal to the height of the liquid outlet 39, which reduces the probability that the quenching liquid will not quench the device and will flow out through the liquid outlet 39, thereby improving the quenching efficiency of the flange rapid quenching device.

[0054] In practical use, the operator pumps the quenching liquid into the injection chamber 40 through the inlet 38. When the quenching liquid in the injection chamber 40 reaches a sufficient height and can flow out from the outlet 39, the operator places the flange to be quenched on the guide plate 33. The flange slides off the guide plate 33 onto the buffer assembly 1. The buffer assembly 1 cushions the sliding flange, reducing the impact damage to the quenching device caused by the flange falling. After being cushioned, the flange slides onto the conveying assembly 2. The conveying assembly 2 conveys the flange away from the quenching device. When the flange passes through the injection chamber 40, it will be immersed in the quenching liquid, thus completing the quenching of the flange.

[0055] Combination Figure 2 In one specific embodiment, the buffer assembly 1 includes: a telescopic plate 11, a connecting rod 13, a connecting block 12, and a spring 14; the fixed end of the telescopic plate 11 is rotatably connected to the partition plate 32, the connecting rod 13 is vertically fixedly disposed in the injection chamber 40, the connecting block 12 is sleeved on the connecting rod 13, the connecting rod 13 and the connecting block 12 are slidably connected, the connecting block 12 is rotatably connected to the telescopic end of the telescopic plate 11, the spring 14 is sleeved on the connecting rod 13, one end of the spring 14 is fixedly connected to the lower end of the connecting block 12, and the other end of the spring 14 is fixedly connected to the bottom of the injection chamber 40.

[0056] In this embodiment, the telescopic plate 11 is rectangular in shape, and its telescopic end is rotatably connected to the connecting block 12 via a rotating shaft 35. The rotating shaft 35 is cylindrical, and the connecting rod 13 is cylindrical. The connecting block 12 can drive the rotating shaft 35 to slide along the axis of the connecting rod 13. A vertical groove 42 is provided on the partition plate 32, which is parallel to the width direction of the fixed housing 31. The groove 42 is rectangular in shape, and when the rotating shaft 35 slides under the drive of the connecting block 12, the rotating shaft 35 slides exactly within the groove 42. That is, the partition 32 is located in the middle of the connecting rod 13 and the telescopic plate 11. When the flange slides off the telescopic plate 11, the partition 32 can protect the connecting rod 13 and reduce the probability of deformation and damage caused by the flange colliding with the connecting rod 13. A buffer pad 34 is provided on the periphery of the fixed end of the telescopic plate 11. The material of the buffer pad 34 is a flexible high-temperature resistant material. In this embodiment, no specific limitation is made. The buffer pad 34 can reduce the impact intensity of the flange on the telescopic plate 11 and improve the service life of the telescopic plate 11.

[0057] In practical use, when the flange slides from the guide plate 33 onto the telescopic plate 11, the telescopic end of the telescopic plate 11 is affected by the weight of the flange, causing the telescopic plate 11 to tilt from a horizontal state. The telescopic end of the telescopic plate 11 extends and drives the connecting block 12 to move along the axis of the connecting rod 13 towards the bottom of the injection chamber 40. The movement of the connecting block 12 will compress the spring 14. The compression of the spring 14 consumes the power of the flange sliding down, thus achieving the function of replacing the flange. When the tilt angle of the telescopic plate 11 is large, the flange slides from the telescopic plate 11 onto the conveying assembly 2. The spring 14 changes from a compressed state to an extended state. The extension of the spring 14 drives the connecting block 12 to move along the axis of the connecting rod 13 away from the bottom of the injection chamber 40. The movement of the connecting block 12 causes the telescopic end of the telescopic plate 11 to move synchronously and shorten. The telescopic plate 11 changes from a tilted state to a horizontal state, which is convenient for the next buffering.

[0058] Combination Figure 3 and Figure 4 In one specific embodiment, the conveying component 2 includes: a motor 21, a driving roller 22, a driven roller 23, a sprocket 25, a transmission chain 24, and a transport plate 26; the motor 21 is fixedly mounted on the fixed housing 31, and the output end of the motor 21 passes through the fixed housing 31; the driving roller 22 is rotatably mounted on the fixed housing 31, and one end of the driving roller 22 is fixedly connected to the output end of the motor 21; the driven roller 23 is rotatably mounted on the fixed housing 31, and both the driven roller 23 and the driving roller 22 are parallel to one side of the width direction of the fixed housing 31; the sprocket 25 is fixedly mounted on the driving roller 22 and the driven roller 23 respectively, and the sprocket 25 on the driving roller 22 and the sprocket 25 on the driven roller 23 are correspondingly arranged; the transmission chain 24 is wound around the two sets of sprockets 25 respectively; and the transport plate 26 is rotatably mounted on the transmission chain 24.

[0059] In this embodiment, the rotation of the output end of the motor 21 is not affected by the fixed housing 31. The driving roller 22 is cylindrical, and the rotation of the motor 21 will drive the driving roller 22 to rotate synchronously. The driven roller 23 is cylindrical, and two sets of driven rollers 23 are provided at the bottom of the injection chamber 40. Two sets of sprockets 25 and transmission chains 24 are spaced apart along the axis of the driving roller 22. That is, each driving roller 22 and driven roller 23 is provided with two sets of sprockets 25. The sprockets 25 on the driving roller 22, the sprockets 25 on the driven roller 23, and the transmission chains 24 are correspondingly arranged. One end of the transport plate 26 in the width direction is rotatably connected to the transmission chain 24, and the other end of the transport plate 26 in the width direction is provided with a protruding plate 36. When the transport plate 26 is conveying the flange, the protruding plate 36 can prevent the flange from sliding to the side opposite to the direction of movement of the transport plate 26. The transport plate 26 is spaced apart along the length direction of the transmission chain 24. Multiple sets of transport plates 26 are provided, enabling the sequential transport of multiple quenched flanges. Multiple sets of anti-slip ridges 37 are spaced apart on the transport plates 26, increasing the friction between the transport plates 26 and the flanges, thereby improving the transport capacity of the conveying assembly 2. Multiple sets of drain holes 43 are also spaced apart on the transport plates 26, allowing the quenching liquid on the transport plates 26 to flow quickly into the injection chamber 40, reducing the probability of the quenching liquid leaving the injection chamber 40 after passing through the conveying assembly 2, thus reducing quenching liquid loss and saving quenching costs for the flange rapid quenching device. By setting multiple sets of transport plates 26 to improve the transport capacity of the conveying assembly 2, the transport efficiency of the quenching device for quenched flanges is improved, enabling the quenching device to sequentially transport multiple quenched flanges away from the quenching device, thereby improving the quenching efficiency of the quenching device.

[0060] In practical use, when the flange slides from the telescopic plate 11 onto the transport plate 26, the motor 21 starts. The rotation of the motor 21 drives the drive roller 22 to rotate synchronously. The rotation of the drive roller 22 drives the sprocket 25 connected to the drive roller 22 to rotate synchronously. The rotation of the sprocket 25 drives the transmission chain 24 and the driven wheel to rotate synchronously. The rotation of the transmission chain 24 drives the transport plate 26 to move along the length of the transmission chain 24. When the transport plate 26 carries the flange away from the surface of the quenching liquid, the quenching liquid remaining on the transport plate 26 flows out of the transport plate 26 through the drain hole 43 and flows back into the injection chamber 40. When the transport plate 26 moves to the highest point, the flange falls off the transport plate 26 and detaches from the quenching device. Multiple sets of transport plates 26 follow the transmission chain 24 to continuously transport, so that the quenching device can quench multiple flanges at the same time.

[0061] It should be noted that the motor 21 is electrically connected to an external power source. The flange rapid quenching device is equipped with a PLC control panel, which is electrically connected to the motor 21, so the rotation of the motor 21 can be controlled through the PLC control panel.

[0062] The implementation principle of this application is as follows: The operator pumps the quenching liquid into the injection chamber 40 through the inlet 38. Once the quenching liquid in the injection chamber 40 reaches a sufficient height and can flow out from the outlet 39, the operator places the flange to be quenched onto the guide plate 33. The flange slides from the guide plate 33 onto the telescopic plate 11. The telescopic plate 11 tilts from a horizontal position due to the weight of the flange. The telescopic end of the telescopic plate 11 extends, causing the connecting block 12 to move along the axis of the connecting rod 13 towards the bottom of the injection chamber 40. The movement of the connecting block 12 compresses the spring 14. The compression of the spring 14 absorbs the kinetic energy of the falling flange, thus providing a buffer for the flange. When the telescopic plate 11 tilts... When the angle is large, the flange slides from the telescopic plate 11 onto the transport plate 26. The motor 21 rotates, driving the drive roller 22 and sprocket 25 to rotate synchronously. The sprocket 25 rotates, driving the driven roller 23 and transmission chain 24 to rotate synchronously. The rotation of the transmission chain 24 drives the transport plate 26 to move along the length of the transmission chain 24. When the transport plate 26 moves to the highest point, the flange falls off the transport plate 26 and detaches from the quenching device. When the flange falls from the guide plate 33 into the liquid injection chamber 40, it is immersed in the quenching liquid. After being quenched by the quenching liquid, it is continuously conveyed away from the quenching device by multiple sets of transport plates 26. This reduces the number of steps required for workers to remove the flange from the quenching liquid, reduces the workload of workers, and improves the quenching efficiency of the quenching device.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
