[0002] Powder metallurgy parts are porous materials. Taking advantage of this, the pores in powder metallurgy parts can be filled with oil to serve as an oil-containing self-lubricating material.

[0003] However, when powder metallurgy parts require electroplating, the pores need to be sealed with resin to prevent the electroplating solution from entering and affecting corrosion resistance. Similarly, some casting products may experience air or oil leaks due to shrinkage cavities, which also require sealing.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1 like Figure 1-3 As shown, this embodiment includes an impregnation shell 10 and a top cover 60 for sealing connection with the impregnation shell 10; the impregnation shell 10 is provided with an impregnation chamber 20, a liquid storage chamber 30 and a heating chamber 40 from top to bottom; in this embodiment, the impregnation shell 10 is divided into an impregnation chamber 20, a liquid storage chamber 30 and a heating chamber 40 by two partitions; wherein, the impregnation chamber 20 is used to impregnate powder metallurgy parts; the liquid storage chamber 30 is used to store the impregnation liquid; and the heating chamber 40 is provided with a heating device for heating the impregnation liquid in the liquid storage chamber 30. In this embodiment, a heating resistance wire is also provided in the heating chamber 40. The heating resistance wire is used to heat the impregnation liquid in the storage chamber 30. On the one hand, it can improve the fluidity of the impregnation liquid and improve the impregnation effect. On the other hand, it does not directly contact the impregnation liquid in the storage chamber 30, so that the heating is more uniform and at the same time, it reduces the burn damage of the impregnation liquid caused by the local high temperature of the heating component.

[0025] In this embodiment, the heating resistance wires are evenly distributed on the inner wall of the heating chamber to ensure a uniform temperature field distribution and avoid local overheating that could lead to deterioration of the impregnating agent. The power of the resistance wires is dynamically adjusted by the temperature controller based on the thermocouple feedback signal to achieve precise temperature control. The surface of the resistance wires is wrapped with high-temperature resistant insulating material to improve safety and service life.

[0026] The impregnation shell 10 is provided with an inlet and outlet pipe that communicates with the liquid storage chamber 30. The inlet and outlet pipe is used to inject impregnation liquid into the liquid storage chamber 30 or to discharge waste liquid. Its position is set at the lower part of the side wall of the liquid storage chamber 30 to ensure that the liquid can be fully discharged or injected. The inlet and outlet pipe is provided with a control valve to regulate the inlet and outlet flow rate of the impregnation liquid to ensure that the filling or discharge process is controllable. The control valve is a solenoid valve or a manual valve, which can be selected according to the actual working conditions.

[0027] In this embodiment, the impregnation shell 10 is provided with a conveying assembly that transports the liquid in the storage chamber 30 to the impregnation chamber 20; in this embodiment, the conveying assembly can also cause the impregnating liquid in the impregnation chamber 20 to flow back to the storage chamber 30.

[0028] The delivery assembly includes a delivery pipe 31 that connects the impregnation chamber 20 and the liquid storage chamber 30. In this embodiment, the delivery pipe 31 is disposed outside the impregnation shell 10, thereby enabling liquid transfer between the impregnation chamber 20 and the liquid storage chamber 30 through the delivery pipe 31.

[0029] The delivery pipe 31 is equipped with a liquid pump 32 and a first solenoid valve 33. The liquid pump 32 is used to provide power to transport the impregnation liquid in the storage chamber 30 to the impregnation chamber 20 through the delivery pipe 31, or to pump the liquid after impregnation in the impregnation chamber 20 back to the storage chamber 30. The first solenoid valve 33 is used to control the opening and closing of the delivery pipe 31, and cooperates with the liquid pump 32 to realize the directional flow of the impregnation liquid.

[0030] In one embodiment, the delivery pipe 31 is disposed inside the impregnation housing 10 to reduce the space occupied by external pipelines and improve system integration. In this case, the delivery pipe 31 passes through the partition and is connected to the impregnation chamber 20 and the liquid storage chamber 30. At the same time, the liquid pump 32 is fixed inside the impregnation housing 10 by a built-in installation method and is integrated with the delivery pipe 31 to reduce the risk of leakage. The first solenoid valve 33 is also built into the housing and is automatically opened and closed by the control system according to the process flow to ensure that the liquid flow direction is accurate and controllable. The entire delivery assembly works in concert according to a preset program during operation to realize the quantitative, directional and timely transmission of the impregnation liquid, thereby improving the stability and repeatability of the impregnation process.

[0031] In this embodiment, the impregnation shell 10 is provided with a vacuum assembly that communicates with the impregnation chamber 20; the vacuum assembly is used to evacuate the impregnation chamber 20 to remove air from inside the powder metallurgy parts and improve the impregnation effect.

[0032] The vacuum assembly includes a vacuum delivery pipe 35 connected to the impregnation chamber 20. A vacuum pump 36 and a second solenoid valve 37 are mounted on the vacuum delivery pipe 35. In this embodiment, the vacuum delivery pipe 35 is a three-way pipe, with its first end connected to the impregnation chamber 20 and its second end connected to the liquid storage chamber 30. The vacuum pump 36 is mounted on the third end of the three-way pipe. The first end of the three-way pipe is equipped with a second solenoid valve 37, and both the first and second ends are equipped with solenoid valves (not marked in the figure). Thus, the vacuum pump 36 is used to evacuate the impregnation chamber 20 and the liquid storage chamber 30, causing the internal air pressure of both chambers to decrease synchronously, thereby shortening the evacuation time. The second solenoid valve 37 and the solenoid valves are used to control the opening and closing of the vacuum delivery pipe 35, ensuring that the establishment and dissipation of the vacuum environment are controllable. The vacuum pump 36, the second solenoid valve 37, and the solenoid valves work together to quickly expel air from the impregnation chamber 20 before impregnation, improving the impregnation efficiency, and transferring liquid during the reflux stage.

[0033] In this embodiment, the impregnation shell 10 is provided with a compressed air assembly communicating with the impregnation chamber 20; the compressed air assembly includes a compressed cavity pipe (not shown in the figure) communicating with the impregnation chamber 20, and a pressure regulating valve (not shown in the figure) and a compressed air pump (not shown in the figure) are provided on the compressed cavity pipe; when the compressed air pump is running, clean compressed air can be introduced into the impregnation chamber 20 through the compressed cavity pipe, pushing the pressure in the chamber to rise, thereby accelerating the penetration of the impregnating liquid into the micropores of the workpiece; this process is carried out after vacuum treatment, forming an alternating cycle of "vacuum-pressurization", which significantly improves the impregnation efficiency and depth; the pressure regulating valve can precisely control the incoming air pressure, thereby adjusting the pressure according to the porosity, pore size and impregnation requirements of the workpiece.

[0034] Simultaneously, the compressed air assembly, after sufficiently impregnating the impregnating parts in the impregnation chamber 20, can push the impregnating liquid in the impregnation chamber 20 back to the storage chamber 30 through the positive pressure of compressed air, achieving efficient recovery; this backflow process is coordinated by the control system to synchronize the operation of the first solenoid valve 33 and the compressed air pump, ensuring that the residual liquid in the impregnation chamber is completely discharged, reducing waste and avoiding cross-contamination; the entire backflow path is sealed to prevent leakage.

[0035] The impregnation chamber 20 is equipped with a turntable assembly for placing the impregnated workpiece; thus, after the workpiece is impregnated, the rotation of the turntable assembly can drive the workpiece to rotate, promote the uniform discharge of excess impregnation liquid, and reduce surface residue.

[0036] The turntable assembly includes several roller frames 21 arranged in a ring within the impregnation chamber 20. In this embodiment, the roller frame 21 includes a support column and a rolling shaft arranged on the support column. Thus, the rolling shaft can rotate along its own axis, the support column is fixed to the bottom of the impregnation chamber 20, and the multiple roller frames 21 form a ring-shaped bearing area.

[0037] A concave turntable 22 is provided on several roller frames 21, and a turntable column 26 is provided between the concave turntable 22 and the bottom of the impregnation chamber 20. The concave turntable 22 and the turntable column 26 are rotatably connected. In this embodiment, the turntable column 26 and the concave turntable 22 are rotatably connected by bearings. The turntable column 26 is fixed at the bottom of the impregnation chamber 20. The concave turntable 22 is also located on several roller frames 21. Thus, the concave turntable 22 achieves relative rotation with the turntable column 26 through the bearings, and at the same time, combined with the rotation of the rolling shaft, the concave turntable 22 can achieve uniform support under the action of the roller frames 21, ensuring that the concave turntable 22 is subjected to balanced force during the impregnation process and avoiding deformation or damage caused by local stress concentration.

[0038] A plurality of drain channels 25 are evenly provided on the concave turntable 22. In this embodiment, the plurality of drain channels 25 evenly penetrate the side wall of the concave turntable 22. Thus, the concave surface of the concave turntable 22 faces upward to support the workpiece to be impregnated. The drain channels 25 are used to enable the impregnating liquid to quickly penetrate and evenly distribute on the surface of the workpiece when it is immersed or removed. At the same time, it effectively discharges residual liquid during the reflow stage, reduces dead corners, and improves process consistency.

[0039] In this embodiment, a pin hole post 23 is fixedly connected to the middle of the concave turntable 22, and a rotating pin hole 24 is provided at the top of the pin hole post 23; a lifting and rotating assembly 50 is provided on one side of the impregnation shell 10, and a driving assembly for driving the turntable assembly to rotate is provided on the lifting and rotating assembly 50; thereby, the turntable assembly is driven to rotate by the driving assembly, so that the impregnated workpiece on the turntable assembly can achieve uniform dehydration during the rotation process.

[0040] The lifting and rotating assembly includes a rotating component (not shown in the figure) and a lifting component 51 disposed on the rotating component. In this embodiment, the rotating component includes a rotating motor, a rotating cylinder, or other rotatable mechanisms; the lifting component 51 includes a linear slide rail, a telescopic cylinder, or other lifting mechanisms.

[0041] The lifting component 51 is provided with a cantilever 52. In this embodiment, the output end of the lifting component 51 is fixedly connected to the cantilever 52. Then, the operation of the rotating component and the lifting component 51 drives the cantilever 52 to move up and down precisely in the vertical direction, and cooperates with the rotating component to achieve multi-angle rotation.

[0042] A rotating shaft 53 is provided on the side of the cantilever 52 facing the turntable assembly. The first end of the rotating shaft 53 passes through the cantilever 52 and is connected to a rotary motor 54. The second end of the rotating shaft 53 is fixedly connected to a pivot pin 55 that matches the pivot pin hole 24. Thus, the rotary motor 54 drives the rotating shaft 53 to rotate, causing the pivot pin 55 at its end to be fixed to the pivot pin hole 24. In this embodiment, the pivot pin 55 is a triangular pivot pin, and the pivot pin hole 24 is a triangular pivot pin hole. This achieves synchronous rotation drive of the concave turntable 22. When the lifting component 51 drives the cantilever 52 to descend, the pivot pin 55 is fixedly engaged with the pivot pin hole 24. The rotary motor 54 starts and transmits torque through the rotating shaft 53, causing the concave turntable 22 to rotate around its central axis to adapt to the requirements of different process stages for the workpiece impregnation angle. When rising, the pivot pin 55 disengages from the pivot pin hole 24 to avoid interfering with subsequent workpiece loading and unloading operations. This structural design realizes automatic docking and disengagement of the transmission connection, improving the automation level and operating efficiency of the equipment.

[0043] The top cover 60 also includes a pressure cap 56; in this embodiment, the pressure cap 56 is fixedly connected to the rotating shaft 53 by a bearing and is located above the pivot pin 55; the top cover 60 is located on top of the impregnation shell 10 and can be sealed to the impregnation shell 10.

[0044] In this embodiment, the diameter of the gland 56 is smaller than the diameter of the impregnation cavity 20, and the gland 56 can be sealed to the concave turntable 22.

[0045] The outer wall of the top cover 60 is provided with several protrusions 61. Below the protrusions 61 and on the impregnation shell 10, there is a mounting seat 65. The mounting seat 65 is provided with a rotary cylinder 66. The output shaft of the rotary cylinder 66 is connected to a pressure block 67 for pressing the protrusions 61. Thus, when the top cover 60 is closed to the impregnation shell 10, the rotary cylinder 66 is activated, driving the pressure cap 56 to press down and lock onto the protrusions 61, achieving a pre-tight seal between the top cover 60 and the impregnation shell 10, ensuring no leakage in the impregnation chamber 20 during pressurization. The rotary cylinder 66 provides a stable downward pressure, forming a reliable surface contact seal between the pressure cap 56 and the protrusions 61, effectively withstanding internal pressure changes. This locking action is automatically executed after the cover is closed, and with the help of sensor feedback, it achieves confirmation of position, improving operational safety and automation. Before opening the cover, the rotary cylinder 66 reverses its action to release the pressure cap 56, facilitating the smooth opening of the top cover 60 and ensuring smooth loading and unloading procedures.

[0046] The impregnation shell 10 is also provided with a support 70, and a top cover cylinder 71 is provided on the support 70. The output shaft of the top cover cylinder 71 is connected to a connecting plate 72. The top cover 60 is also provided with a crossbeam 73, and the first end of the crossbeam 73 is hinged to the connecting plate 72. In this embodiment, the crossbeam 73 is fixedly connected to the top cover 60. Thus, the extension and retraction movement of the top cover cylinder 71 drives the connecting plate 72 to further seal the crossbeam 73 and the top cover 60 with the impregnation shell 10, ensuring the reliability of the seal between the top cover 60 and the impregnation shell 10. When the top cover cylinder 71 extends, the crossbeam 73 presses down synchronously to achieve a seal. When the cover is opened, the top cover cylinder 71 retracts, causing the crossbeam 73 to drive the top cover 60 away from the impregnation shell 10.

[0047] The support 70 is provided with a symmetrical first bracket 74 and a second bracket 75, which are located between the top cover cylinder 71 and the impregnation shell 10. The crossbeam 73 is located between the first bracket 74 and the second bracket 75. The first bracket 74 is provided with a support shaft 76, and the first end of the support shaft 76 passes through the crossbeam 73 and is rotatably connected to the second bracket 75. Thus, the two ends of the support shaft are rotatably connected to the first bracket and the second bracket respectively, providing a stable rotation fulcrum for the swing of the crossbeam 73, ensuring that it moves synchronously and smoothly under the drive of the top cover cylinder 71. This symmetrical arrangement effectively balances the forces on both sides, avoids uneven loading or jamming during the pressing process, and improves the overall reliability of the mechanism.

[0048] The first support 74 is also provided with a first limiting hole, and a safety pin 77 is provided in the limiting hole. The crossbeam 73 is provided with a second limiting hole for the safety pin 77 to pass through, and the second support 75 is also provided with a third limiting hole for the safety pin 77 to pass through. Thus, by setting the safety pin 77, the relative position of the crossbeam 73 with the first support 74 and the second support 75 can be further fixed, preventing the top cover cylinder 71 from accidentally moving and causing the clamping force to be released. It also ensures that the locking state of the top cover 60 is not released during equipment maintenance or sudden power failure. The safety pin 77 and the limiting hole cooperate to form a mechanical interlock, which enhances the inherent safety of the device and avoids the cover closing accident caused by misjudgment of the control system or failure of components.

[0049] The top cover 60 is equipped with an observation window 57 and a light illumination window 58, both of which are sealed with transparent material. Thus, the operator can monitor the internal working conditions of the impregnation chamber 20 in real time through the observation window 57, and with the lighting provided by the light illumination window 58, clearly understand the impregnation status of the workpiece and changes in the liquid level, especially during the pressure sealing process, to promptly detect abnormal bubbles or signs of leakage. The transparent material has sufficient mechanical strength and corrosion resistance to ensure that it will not become blurred or cracked during long-term use, thus improving the convenience of operation and maintenance while ensuring sealing.

[0050] The impregnation chamber 20 is equipped with a first electronic vacuum gauge; the liquid storage chamber 30 is equipped with a second electronic vacuum gauge; and the heating chamber 40 is equipped with a thermocouple and a temperature controller. The first electronic vacuum gauge is used to monitor the vacuum level in the impregnation chamber in real time, ensuring that the workpiece is fully degassed under negative pressure, thereby improving the impregnation efficiency. The second electronic vacuum gauge monitors the vacuum status of the liquid storage chamber, ensuring that the impregnation agent is stably transported under bubble-free conditions. The thermocouple and the temperature controller work together to precisely regulate the temperature of the heating chamber, maintaining the impregnation agent within the optimal process temperature range. The signals from each sensor are connected to the central control system to achieve fully automated monitoring and data recording, ensuring that the processing parameters for each batch are traceable and meeting the stringent requirements for process consistency in the high-end manufacturing field.

[0051] When the impregnation and descaling equipment of this application is not in operation, the impregnation shell 10 is sealed (top cover closed, safety pin in the disengaged position); when impregnation of parts is required, the specific steps are as follows: First, the rotary cylinder 66 rotates, causing the pressure block 67 to disengage from the boss 61; the top cover cylinder 71 retracts, driving the crossbeam 73 to open the top cover 60 under the action of the supporting shaft 76; then the safety pin 77 on the first bracket 74 is inserted into the positioning hole of the second bracket 75 and the crossbeam 73 to ensure that the top cover 60 remains in a stable locked state during the opening process. Place the part to be impregnated into the concave turntable 22; the safety pin 77 is removed from the second bracket 75 and the crossbeam 73; the top cover cylinder 71 extends and drives the crossbeam 73 to seal the top cover 60 with the impregnation shell 10 under the action of the supporting rotating shaft 76; then the rotating cylinder 66 drives the pressure block 67 to press the boss 61, so that the top cover 60 and the impregnation shell 10 are further sealed. Then the vacuum assembly is activated, namely the second solenoid valve 37 connected to the impregnation chamber 20 and the solenoid valve connected to the liquid storage chamber 30 are opened; the vacuum pump 36 is started to evacuate the impregnation chamber 20 and the liquid storage chamber 30. After the first electronic vacuum gauge and the second electronic vacuum gauge monitor that the impregnation chamber 20 and the liquid storage chamber 30 have reached the set vacuum level, the second solenoid valve 37, the solenoid valve, and the vacuum pump 36 are closed. The first solenoid valve 33 is opened, and the liquid pump 32 is started to pump the impregnation liquid in the storage chamber 30 into the impregnation chamber 20. After the impregnation liquid has submerged the parts, the first solenoid valve 33 and the liquid pump 32 are closed. Open the pressure regulating valve and start the compressed air pump to fill the impregnation chamber 20 with compressed air to accelerate the impregnation liquid into the workpiece pores; after impregnation is completed, open the first solenoid valve 33 to allow the impregnation liquid to flow back to the storage chamber 30 under the action of compressed air; after the return is completed, close the first solenoid valve 33 and open the second solenoid valve 37 to release the air pressure in the impregnation chamber 20. Rotating cylinder 66 causes pressure block 67 to disengage from boss 61; top cover cylinder 71 retracts, causing crossbeam 73 to open top cover 60 under the action of supporting shaft 76; then safety pin 77 on first bracket 74 is inserted into positioning hole of second bracket 75 and crossbeam 73 to ensure that top cover 60 remains in a stable locked state during opening. Open the first solenoid valve 33, and the rotating and lifting components 51 operate, causing the cantilever 52 to rotate towards the impregnation chamber 20. When the pivot pin 55 on the cantilever 52 aligns with the pivot pin hole 24, the lifting component 51 drives the cantilever 52 to descend, allowing the pivot pin 55 to insert into the pivot pin hole 24 (it has a taper, so even with some deviation, it can still be inserted). At the same time, the pressure cap 56 covers the concave turntable 22 to prevent the workpiece or impregnation liquid from flying out during rotation. The rotary motor 54 starts and drives the concave turntable 22 to rotate, using centrifugal force to remove the impregnation liquid from the surface of the workpiece, which then flows through the leakage channel 25 into the impregnation chamber and then into the storage chamber 30 through the delivery pipe 31. After centrifugation is complete, the rotary motor 54 stops, and the cantilever 52 resets under the operation of the rotating and lifting components 51. Close the first solenoid valve 33 and remove the impregnated workpiece.

[0052] It should be noted that all actions are controlled by a program on the main control panel, and parameters such as impregnation time, vacuum level, pumping time, centrifugation time, centrifugation speed, compressed air pressure, and heating temperature can be set via the touchscreen. The program can be fully automatic or manually operated in steps, facilitating equipment operation.

[0053] Example 2 like Figure 4-6 As shown, the difference between this embodiment and Embodiment 1 is that: The top cover 60 is fixedly connected to the rotating shaft 53 via a bearing and is located above the pivot pin 55. Thus, the top cover 60 rises and falls synchronously with the rotating shaft 53 and can form a sealing fit with the top of the impregnation chamber 20, further enhancing the airtightness of the chamber. When the cantilever 52 descends to the working position, the top cover 60 presses against the impregnation shell 10 to achieve a seal. When rising and resetting, the top cover 60 disengages synchronously with the rotating shaft 53, facilitating workpiece replacement.

[0054] Simultaneously, when the cantilever 52 rises to its reset position, the pivot pin 55 disengages from the pivot pin hole 24, and the top cover 60 separates from the top of the impregnation chamber 20. When the cantilever 52 descends, the pivot pin 55 engages and is fixed with the pivot pin hole 24; the top cover 60 is then sealed to the top of the impregnation chamber 20. Thus, the engagement and disengagement of the pivot pin 55 with the pivot pin hole 24, and the sealing and opening of the top cover 60 with the impregnation chamber 20, are all completed synchronously with the rise and fall of the cantilever 52, achieving integrated linkage control of transmission and sealing.

[0055] When the impregnation and descaling equipment of this application is not in operation, the impregnation shell 10 is sealed (the top cover 60 is sealed to the impregnation shell 10 by the operation of the rotating and lifting components 51; at the same time, the pivot pin 55 on the rotating shaft 53 is aligned with the pivot pin hole 24 in the concave turntable 22 to achieve locking and fixing); when it is necessary to impregnate parts, the specific steps are as follows: First, the lifting component 51 lifts and lowers the top cover 60 to detach it from the impregnation shell 10. Then, the rotating component rotates to move the top cover 60 to the side. Place the part to be impregnated into the concave turntable 22; rotate the rotating component so that the top cover 60 is above the impregnation housing 10; then the lifting component 51 descends so that the top cover 60 and the impregnation housing 10 are sealed; at the same time, the pivot pin 55 on the rotating shaft 53 is aligned with the pivot pin hole 24 in the concave turntable 22 to achieve locking and fixing. Then the vacuum assembly is activated, namely the second solenoid valve 37 connected to the impregnation chamber 20 and the solenoid valve connected to the liquid storage chamber 30 are opened; the vacuum pump 36 is started to evacuate the impregnation chamber 20 and the liquid storage chamber 30. After the first electronic vacuum gauge and the second electronic vacuum gauge monitor that the impregnation chamber 20 and the liquid storage chamber 30 have reached the set vacuum level, the second solenoid valve 37, the solenoid valve, and the vacuum pump 36 are closed. The first solenoid valve 33 is opened, and the liquid pump 32 is started to pump the impregnation liquid in the storage chamber 30 into the impregnation chamber 20. After the impregnation liquid has submerged the parts, the first solenoid valve 33 and the liquid pump 32 are closed. Open the pressure regulating valve and start the compressed air pump to fill the impregnation chamber 20 with compressed air to accelerate the impregnation liquid into the workpiece pores; after impregnation is completed, open the first solenoid valve 33 to allow the impregnation liquid to flow back to the storage chamber 30 under the action of compressed air; after the return is completed, close the first solenoid valve 33 and open the second solenoid valve 37 to release the air pressure in the impregnation chamber 20. Open the first solenoid valve 33, start the rotary motor 54 to drive the concave turntable 22 to rotate, use centrifugal force to remove the impregnation liquid from the surface of the parts, and let it flow into the impregnation chamber through the leakage channel 25, and then into the storage chamber 30 through the delivery pipe 31; after centrifugation is completed, the rotary motor 54 stops, and the cantilever 52 is reset under the operation of the rotating part and the lifting part 51; close the first solenoid valve 33; take out the impregnated parts.
