Description

Technical Field

[0001] This utility model relates to the field of nanocrystalline iron core processing technology, specifically to a nanocrystalline iron core impregnation and shaping device. Background Technology

[0002] Nanocrystalline iron cores refer to iron core materials made from nanocrystalline iron powder. During the preparation process, nanocrystalline iron cores undergo impregnation and shaping to reduce their hysteresis and eddy current losses. In the prior art, patent CN 221652428 U discloses an impregnation device for a motor iron core, including a stand and a vibration mechanism installed on the inner wall of the stand. A motor rotates, driving a turntable to rotate, causing a ramp block fixed at the top of the turntable to rotate. When the ramp block passes under a pulley column, it lifts the pulley column, causing a small upward and downward movement. The pulley column, limited by a cover plate, then lifts the vibrating block, completing the upward and downward movement. By adjusting the motor's rotation speed, the vibrating block can vibrate the housing, thus stimulating the impregnation of the motor iron core inside the housing. Vibration accelerates the process of impregnating the insulating material into the gaps between silicon steel sheets to improve the insulation performance and thermal stability of the motor core. This can reduce eddy current losses, improve motor efficiency, and increase the motor's heat resistance. However, during the impregnation process, the device uses clamps to squeeze and fix the impregnated core. The surface of the core at the point of contact between the clamps is not conducive to the penetration of the impregnation liquid, resulting in an unsatisfactory impregnation effect. In addition, the device uses natural impregnation to treat the core, leaving room for improvement in the impregnation efficiency. Therefore, we propose a nanocrystalline core impregnation and shaping device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a nanocrystalline iron core impregnation and shaping device. This device extracts the gas in the gaps of the nanocrystalline iron core by drawing a vacuum. Then, the impregnation liquid can quickly penetrate into the gaps of the nanocrystalline iron core under negative pressure and its own gravity, thereby improving the impregnation efficiency of the device on the nanocrystalline iron core. At the same time, the device uses a transmission element to continuously change the impregnation support part of the nanocrystalline iron core, thereby avoiding the impregnation effect of the nanocrystalline iron core in the part that is not ideal due to continuous contact. This can effectively solve the problems in the background art.

At the same time, the device uses a transmission element to continuously change the impregnation support part of the nanocrystalline iron core, thereby avoiding the impregnation effect of the nanocrystalline iron core in that part being less than ideal due to continuous contact.

[0006] Furthermore, it also includes a microcontroller, which is located outside the workbench.

The middle of the lifting plate is provided with a sliding column, and one end of the sliding column near the center of the lifting plate is slidably connected to the annular wave groove. The lower side of the partition plate is provided with a low-speed motor. The input end of the low-speed motor is electrically connected to the output end of the microcontroller. The output shaft of the low-speed motor is fixedly connected to the lower end of the rotating shaft, so that the lifting plate in the nanocrystalline iron core impregnation and shaping equipment can move vertically up and down reciprocally.

[0009] Furthermore, the material conveying assembly includes a storage tank, an inlet pipe, an outlet pipe, a solenoid valve, and a pump. The storage tank is located on the upper left side of the workbench. The right wall of the storage tank is connected to the impregnation shell through the inlet pipe, and the bottom wall of the storage tank is connected to the impregnation shell through the outlet pipe. The right ends of both the inlet and outlet pipes are connected in series with the solenoid valve, and the left ends of both the inlet and outlet pipes are connected in series with the pump. The input ends of both the solenoid valve and the pump are electrically connected to the output end of the microcontroller to supply nanocrystalline iron core impregnation solution to the interior of the impregnation shell.

[0010] Furthermore, the vacuum assembly includes a vacuum pump, a suction pipe, a pressure relief pipe, a second solenoid valve, and vacuum gauges. The vacuum pump is located on the upper right side of the workbench. The suction port of the vacuum pump is connected to the impregnation shell through the suction pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This nanocrystalline iron core impregnation and shaping equipment has the following advantages:

[0013] When using the nanocrystalline iron core impregnation and shaping equipment, the device extracts the gas from the gaps in the nanocrystalline iron core by drawing a vacuum. Then, under negative pressure, the impregnation liquid can quickly penetrate into the gaps of the nanocrystalline iron core by its own gravity, thereby improving the impregnation efficiency of the nanocrystalline iron core. At the same time, the device uses a lifting component and a wave groove sliding contact guide to continuously change the impregnation support part of the nanocrystalline iron core, thereby avoiding the impregnation effect of the nanocrystalline iron core in that part being less than ideal due to continuous contact.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a nanocrystalline iron core impregnation and shaping device, including a workbench 1, an impregnation shell 3 on the upper side of the workbench 1, a top cover 4 installed on the upper end of the impregnation shell 3, a drying chamber 9 on the right side of the workbench 1, and a microcontroller 2 located outside the workbench 1. The input end of the microcontroller 2 is electrically connected to an external power supply, and the output end of the microcontroller 2 is electrically connected to the input end of the drying chamber 9. An electro-hydraulic push rod 5 is provided at the upper front end of the workbench 1, and the input end of the electro-hydraulic push rod 5 is electrically connected to the output end of the microcontroller 2. A telescopic rod 6 is provided at the upper rear end of the workbench 1. The telescopic ends of the electro-hydraulic push rod 5 and the telescopic rod 6 are both fixedly connected to the lower side of the top cover 4. A rubber sealing ring 8 is provided at the lower outer edge of the top cover 4. When impregnating the nanocrystalline iron core, the microcontroller 2 activates the electro-hydraulic push rod 5. The telescopic end extends and retracts, thereby causing the top cover 4 to move upward, exposing the upper opening of the impregnation shell 3. During this process, the microcontroller 2 controls the extension distance of the telescopic end of the electro-hydraulic push rod 5 based on the movement distance of the telescopic end per unit time and in conjunction with its own internal timing unit. After the nanocrystalline iron core is impregnated, the staff takes out the impregnated nanocrystalline iron core and air-dries it naturally for 7-8 hours. Then, it is placed in the drying oven 9. The microcontroller 2 starts the drying oven 9. The drying oven 9 runs by circulating air through the fan, sending hot air into the oven. The air is heated and recycled through the air duct to ensure that the temperature inside the oven is uniform and maintained at about 120°C for two hours of heating and drying. This heats and sculpts the impregnated nanocrystalline iron core through heating and curing. The process also includes a vacuum impregnation mechanism 7.

[0021] Vacuum impregnation mechanism 7: It includes a partition plate 71, telescopic columns 72, lifting plate 73, top column 74, placement plate 75, suspended column 76, lifting assembly 77, conveying assembly 78, and vacuum assembly 79. The partition plate 71 and placement plate 75 are both located inside the impregnation shell 3. The placement plate 75 is located above the partition plate 71. A lifting plate 73 is provided on the upper side of the partition plate 71 via the telescopic ends of the evenly distributed annular telescopic columns 72. Evenly distributed top columns 74 are provided on the upper side of the lifting plate 73. Evenly distributed through holes are opened inside the placement plate 75. The top columns 74 are vertically aligned with adjacent through holes. Evenly distributed suspended columns 76 are provided on the upper side of the placement plate 75. A lifting assembly 77 is provided between the partition plate 71 and the lifting plate 73. A worktable is also provided. A material conveying assembly 78 is provided between the worktable 1 and the impregnation shell 3. A vacuum assembly 79 is provided between the worktable 1, the impregnation shell 3, and the top cover 4. The lifting assembly 77 includes a rotating shaft 771, a rotating column 772, an annular wave groove 773, a sliding column 774, and a low-speed motor 775. The rotating shaft 771 is rotatably connected to the middle of the partition plate 71 via a double-row tapered bearing. The upper end of the rotating shaft 771 is provided with the rotating column 772. The outer arc surface of the rotating column 772 is provided with an annular wave groove 773. The middle of the lifting plate 73 is provided with a sliding column 774. One end of the sliding column 774 near the center of the lifting plate 73 is slidably connected to the annular wave groove 773. The lower side of the partition plate 71 is provided with a low-speed motor 775. The input end of the low-speed motor 775 is electrically connected to the output end of the microcontroller 2. The output shaft is fixedly connected to the lower end of the rotating shaft 771. The material conveying assembly 78 includes a storage tank 781, an inlet pipe 782, an outlet pipe 783, a solenoid valve 784, and a pump 785. The storage tank 781 is located on the upper left side of the workbench 1. The right wall of the storage tank 781 is connected to the impregnation shell 3 through the inlet pipe 782, and the bottom wall of the storage tank 781 is connected to the impregnation shell 3 through the outlet pipe 783. The right ends of the inlet pipe 782 and the outlet pipe 783 are connected in series with the solenoid valve 784, and the left ends of the inlet pipe 782 and the outlet pipe 783 are connected in series with the pump 785. The input ends of the solenoid valve 784 and the pump 785 are electrically connected to the output end of the microcontroller 2. The vacuum assembly 79 includes a vacuum pump 791, a suction pipe 792, a pressure relief pipe 793, and an electric pump 785. The second solenoid valve 794 and vacuum gauge 795, along with the vacuum pump 791, are located on the upper right side of the workbench 1. The suction port of the vacuum pump 791 is connected to the impregnation shell 3 via the suction pipe 792. A pressure relief pipe 793 is located on the upper side of the top cover 4, with the second solenoid valve 794 connected in series in the middle of the pressure relief pipe 793. The input ends of both the second solenoid valve 794 and the vacuum pump 791 are electrically connected to the output end of the microcontroller 2. The inner wall of the impregnation shell 3 is equipped with evenly distributed vacuum gauges 795, all of which are bidirectionally electrically connected to the microcontroller 2. The impregnation liquid is stored through the storage box 781. The operator evenly places the nanocrystalline iron cores onto the suspended column 76, ensuring that the bottom of the nanocrystalline iron cores does not contact the placement plate 75. Subsequently, the microcontroller 2 controls the electro-hydraulic push rod 5 to retract and reset its telescopic end.This allows the top cover 4 to seal the upper opening of the impregnation shell 3. During the vertical movement of the top cover 4, the telescopic end of the telescopic rod 6 slides adaptively along its fixed end synchronously with the top cover 4. The sliding contact between the telescopic end of the telescopic rod 6 and the fixed end bears the radial pressure applied by the top cover 4 to the telescopic end of the electro-hydraulic actuator 5, thus preventing damage to the telescopic end of the electro-hydraulic actuator 5. The rubber sealing ring 8 uses the pressure deformation of rubber molecules to seal the contact gap between the top cover 4 and the impregnation shell 3, thus facilitating the subsequent vacuuming operation inside the impregnation shell 3. Subsequently, the microcontroller 2 starts the vacuum pump 791. The vacuum pump 791 changes its volume periodically through the reciprocating motion of the piston, thereby evacuating the inside of the impregnation shell 3 through the suction pipe 792. During operation, the microcontroller 2 activates the vacuum gauge 795. Due to the different thermal conductivity of gas molecules under different pressures, when a constant current is applied to the hot wire inside the vacuum gauge 795, the heat carried away by the gas varies depending on the pressure, resulting in different temperatures maintained by the hot wire. This leads to different resistance values ​​in the hot wire. By measuring the resistance of the hot wire, the pressure inside the impregnation shell 3 can be estimated. Subsequently, the vacuum gauge 795 transmits the measurement result to the microcontroller 2 as an electrical signal. The vacuum gauge 795 has multiple sets to improve the accuracy of the measurement results. Based on the measured results, the microcontroller 2 controls the operation of the vacuum pump 791, thereby maintaining the vacuum level inside the impregnation shell 3 at -0.09 MPa, thus extracting the gas from the gaps in the nanocrystalline iron core within the device. To facilitate better entry of the impregnation solution later, the microcontroller 2 then opens the upper solenoid valve 784 and the liquid pump 785, allowing the impregnation solution in the storage tank 781 to enter the impregnation shell 3 through the liquid inlet pipe 782, and vacuum impregnate the nanocrystalline iron core inside the impregnation shell 3. Simultaneously, the microcontroller 2 starts the low-speed motor 775, causing its output shaft to drive the rotating shaft 771 to rotate at a low speed. The rotating shaft 771 then drives the rotating column 772 to rotate at a low speed. During the rotation of the rotating column 772, the sliding compression between the annular wave groove 773 and the sliding column 774 causes the sliding column 774 to drive the lifting plate 73 to move vertically up and down synchronously. When the lifting plate 73 is at its uppermost vertical position, it drives the top column 74 to move synchronously. The top column 74 pushes the nanocrystalline iron core on the suspended column 76 upwards, causing the lower side of the nanocrystalline iron core to separate from the corresponding suspended column 76. This avoids interference with the impregnation of the impregnation liquid due to the lower side of the nanocrystalline iron core always being in contact with the upper side of the suspended column 76, further improving the impregnation effect of the device on the nanocrystalline iron core. When the lifting plate 73 is at the lowest vertical position, the top column 74 is located below the suspended column 76. After the nanocrystalline iron core is impregnated in the device, the microcontroller 2 opens the solenoid valve 794 and closes the low-speed motor 775, solenoid valve 784, and liquid pump 785. The pressure inside and outside the impregnation shell 3 is balanced through the pressure relief pipe 793 (a filter screen is installed at the inlet of the pressure relief pipe 793 to filter impurities from the gas entering the impregnation shell 3).Subsequently, the microcontroller 2 controls the electro-hydraulic actuator 5 using the same principle, causing the top cover 4 to move upward and open. Simultaneously, the microcontroller 2 activates the lower solenoid valve 784 and the lower liquid pump 785. The operation of the liquid pump 785 draws the impregnation liquid from the impregnation shell 3 through the outlet pipe 783 into the storage tank 781. This device extracts gas from the gaps in the nanocrystalline iron core through vacuum extraction. Then, under negative pressure, the impregnation liquid can quickly penetrate into the gaps of the nanocrystalline iron core due to its own gravity, thereby improving the impregnation efficiency of the nanocrystalline iron core. At the same time, the device uses transmission elements to continuously change the impregnation support part of the nanocrystalline iron core, thus avoiding insufficient impregnation effect in that part due to continuous contact.

[0022] The working principle of the nanocrystalline iron core impregnation and shaping equipment provided by this utility model is as follows: The impregnation solution is stored in the storage tank 781. When impregnating the nanocrystalline iron core, the microcontroller 2 activates the electro-hydraulic push rod 5 to extend and retract its telescopic end, thereby driving the top cover 4 upward, exposing the upper opening of the impregnation shell 3. During this process, the microcontroller 2 controls the extension distance of the telescopic end of the electro-hydraulic push rod 5 based on the movement distance of the telescopic end per unit time and its internal timing unit. Subsequently, the operator places the nanocrystalline iron core... The iron cores are evenly distributed on the suspended columns 76, ensuring that the bottom of the nanocrystalline iron cores does not contact the placement plate 75. Then, the microcontroller 2 controls the electro-hydraulic actuator 5 to retract and reset its telescopic end, thereby closing the upper opening of the impregnated shell 3 with the top cover 4. During the vertical movement of the top cover 4, the telescopic end of the telescopic rod 6 slides adaptively along its fixed end, synchronously with the top cover 4. This sliding contact between the telescopic end and the fixed end of the telescopic rod 6 bears the radial pressure applied by the top cover 4 to the telescopic end of the electro-hydraulic actuator 5, thus preventing the electro-hydraulic actuator 5 from... If the telescopic end is damaged, the rubber sealing ring 8 will seal the contact gap between the top cover 4 and the impregnated shell 3 by utilizing the deformation of rubber molecules under pressure. This facilitates the subsequent vacuuming operation inside the impregnated shell 3. Subsequently, the microcontroller 2 starts the vacuum pump 791. The vacuum pump 791 changes its volume periodically through the reciprocating motion of the piston, thereby performing a vacuuming operation inside the impregnated shell 3 through the suction pipe 792. At the same time, the microcontroller 2 starts the vacuum gauge 795. Due to the different thermal conductivity of gas molecules under different pressures, when the vacuum gauge 795 is... When a constant current is applied to the hot wire inside, the heat carried away by the gas varies due to different gas pressures, resulting in different temperatures maintained by the hot wire. This leads to different resistance values ​​of the hot wire. By measuring the resistance of the hot wire, the gas pressure inside the impregnation shell 3 can be estimated. Subsequently, the vacuum gauge 795 transmits the measurement result to the microcontroller 2 as an electrical signal. The vacuum gauge 795 has multiple sets to improve the accuracy of the measurement results. The microcontroller 2 controls the operation of the vacuum pump 791 based on the measured results, thereby maintaining the vacuum level inside the impregnation shell 3 at -0.The pressure is 0.09 MPa, which extracts the gas from the gaps in the nanocrystalline iron core inside the device, thus facilitating the entry of the impregnation liquid later. Then, the microcontroller 2 opens the upper solenoid valve 784 and the liquid pump 785, allowing the impregnation liquid in the storage tank 781 to enter the impregnation shell 3 through the liquid inlet pipe 782, and vacuum impregnates the nanocrystalline iron core inside the impregnation shell 3. Simultaneously, the microcontroller 2 starts the low-speed motor 775, causing its output shaft to drive the rotating shaft 771 to rotate at a low speed. The rotating shaft 771 then drives the rotating column 772 to rotate at a low speed. During the rotation of the rotating column 772, a ring-shaped... The sliding compression between the wave groove 773 and the sliding column 774 causes the sliding column 774 to drive the lifting plate 73 to move vertically up and down synchronously. When the lifting plate 73 is at its uppermost vertical position, it drives the top column 74 to move synchronously. The top column 74 then lifts the nanocrystalline iron core on the suspended column 76, causing the lower side of the nanocrystalline iron core to separate from the corresponding suspended column 76. This avoids interference with the impregnation of the impregnation liquid due to the lower side of the nanocrystalline iron core always being in contact with the upper side of the suspended column 76, further improving the impregnation effect of the device on the nanocrystalline iron core. When plate 73 is at its lowest vertical position, top column 74 is located below suspended column 76. After the nanocrystalline iron core is impregnated in the device, microcontroller 2 opens solenoid valve 794 and closes low-speed motor 775, solenoid valve 784, and liquid pump 785. The pressure inside and outside the impregnation shell 3 is balanced through pressure relief pipe 793 (a filter screen is installed at the inlet of pressure relief pipe 793 to filter impurities from the gas entering the impregnation shell 3). Subsequently, microcontroller 2 controls electro-hydraulic actuator 5 to move the top cover 4 upwards and open it using the same principle. Simultaneously, microcontroller 2 activates solenoid valve 784 on the lower side and the lower... A liquid pump 785 draws the impregnation solution from the impregnation shell 3 through the outlet pipe 783 into the storage tank 781. The worker then removes the impregnated nanocrystalline iron core and allows it to air dry naturally for 7-8 hours. It is then placed in a drying oven 9, which is started by a microcontroller 2. The drying oven 9 operates by circulating hot air through a fan, and the air is heated and recycled through air ducts to ensure a uniform temperature of approximately 120°C within the oven. This two-hour heating and drying process solidifies the impregnated nanocrystalline iron core.

[0023] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32, the electro-hydraulic actuator 5 can be a DYTZB1000-500, the low-speed motor 775 can be a YDS112, the first solenoid valve 784 and the second solenoid valve 794 can both be ZQDF-3Y-40, the vacuum gauge 795 can be a RE12-REF-VAC, the liquid pump 785 can be an HHB-630, the vacuum pump 791 can be an XD-020, and the drying oven 9 can be a DHG-9036A vertical blower drying oven. The microcontroller 2 controls the operation of the electro-hydraulic actuator 5, the low-speed motor 775, the first solenoid valve 784, the liquid pump 785, the vacuum pump 791, the vacuum gauge 795, the second solenoid valve 794, and the drying oven 9 using methods commonly used in the prior art.
