Description

Technical Field

[0001] The present invention relates to the technical field of nano permanent magnet motors, and particularly relates to a nano permanent magnet motor forming system. Background Art

[0002] A nano permanent magnet motor is a motor that combines nano technology and permanent magnet material technology, and has characteristics such as small size, high precision, low power consumption, and high response speed. Its working principle is based on the magnetoelectric effect. By applying a voltage, a magnetic field is generated, which in turn affects the charge distribution of the dielectric layer, thereby generating a driving force to make the motor rotate. The main difference between a nano permanent magnet motor and an ordinary motor lies in its small size and high precision. Ordinary motors are usually large in volume, while the nano permanent magnet motor, due to its small size and precise working principle, can achieve high-precision motion control in a smaller space.

[0003] The most important component in a nano permanent magnet motor is the permanent magnet. In the prior art, the device for preparing and forming the permanent magnet mostly uses a metal powder vacuum hot press. However, in the existing metal powder vacuum hot press in the prior art, its heating method is to heat the mold and the blank through resistance. However, the resistance heating efficiency is very low, and the requirement for the uniformity of the resistance wire is very high. Otherwise, local overheating will occur, which not only takes a long time, but also is difficult to ensure that the mold and the blank reach the required high temperature, which is not conducive to the preparation and forming of the permanent magnet. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a nano permanent magnet motor forming system.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A nano permanent magnet motor forming system includes a box body. A processing table is installed at the bottom of the box body, a base is installed at the bottom of the processing table, a forming mold is installed at the center position inside the processing table, and the bottom end of the forming mold extends into the base. A moving plate is installed inside the box body, an extrusion mold is installed at the bottom of the moving plate, a protective cover is installed inside the base, and a plurality of heating rods for auxiliary heating of the forming mold are installed inside the protective cover. A plurality of knocking mechanisms for vibrating and knocking the forming mold are installed inside the protective cover. An auxiliary loading and unloading mechanism is installed at the top of the processing table for assisting the accurate entry of metal powder into the forming mold and the rapid discharge of the formed components.

[0007] Optionally, a plurality of guide rods are installed inside the box body, the moving plate is slidably matched with the outer walls of the plurality of guide rods, a housing is installed at the top of the box body, a telescopic cylinder is installed inside the housing, and the telescopic end of the telescopic cylinder passes through the box body and is connected to the moving plate.

[0008] Optionally, the auxiliary loading and unloading mechanism includes two first sliding grooves opened inside the processing table. Two first sliders are installed inside both of the two first sliding grooves. The tops of the two first sliders are both connected to a moving rod through an electric telescopic rod.

[0009] Optionally, second sliding grooves are opened on the outer walls of the two moving rods close to each other. Second sliders are installed inside both of the two second sliding grooves. First rotating plates are rotatably installed at the ends of the two second sliders away from the second sliding grooves.

[0010] Optionally, second rotating plates are rotatably installed inside both of the two first rotating plates. Two third sliding grooves are opened inside one side of both of the two second rotating plates. Third sliders are installed inside both of the two third sliding grooves. A rectangular plate is jointly installed at the ends of the two third sliders away from the third sliding grooves.

[0011] Optionally, a sealing door is rotatably installed on the front of the box body, and a blanking guide plate is rotatably installed on the front of the processing table.

[0012] Optionally, two driving lead screws are installed inside the base. Moving blocks are installed on the outer walls of both of the two driving lead screws. The ends of the two moving blocks close to each other are connected to the outer wall of the protective cover.

[0013] Optionally, a heat insulation plate is installed inside the protective cover. A driving motor is installed between the heat insulation plate and the protective cover. A rotating frame is installed at the output end of the driving motor. The bottoms of multiple heating rods are all connected to the rotating frame.

[0014] Optionally, the knocking mechanism includes multiple springs. All of the multiple springs are installed on the inner wall of the protective cover. Multiple rotating blocks are rotatably installed on the inner wall of the protective cover. The ends of the multiple springs away from the protective cover are all connected to the rotating blocks close to them.

[0015] Optionally, knocking blocks are installed at the ends of the multiple rotating blocks away from the rotating parts. All of the multiple knocking blocks are made of high-temperature resistant rubber material.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In this invention, when the device heats the molding die and the metal powder, high temperature is generated by the multiple heating rods arranged inside the protective cover, which can assist in heating the molding die, ensuring that the metal powder inside the molding die is completely heated. The metal powder can have a fast temperature rise speed and be heated more evenly inside the molding die, facilitating the preparation of high-performance permanent magnets.

[0018] 2. In this invention, when the metal powder needs to be poured into the interior of the molding die, the metal powder can be directly placed on the tops of the two rectangular plates of the auxiliary loading and unloading mechanism. The metal powder can automatically slide downward into the interior of the molding die for filling, thus achieving the effect of automatic feeding of the metal powder, avoiding the situation that manual feeding is prone to spilling the metal powder to other positions on the top of the processing table, and improving the accuracy of feeding the metal powder.

[0019] 3. In this invention, after the metal powder enters the interior of the molding die, the molding die is knocked and vibrated by the provided knocking mechanism, which prompts the gaps between the metal powders entering the interior of the molding die to shrink, enabling the metal powder to be filled more fully in the interior of the molding die, facilitating the subsequent hot pressing of the metal powder into a shape, and avoiding the situation that the gaps between the metal powders in the interior of the molding die are too large, resulting in poor forming quality of the subsequent hot-pressed parts.

[0020] 4. In this invention, after the metal powder in the interior of the molding die is prepared into a permanent magnet blank by hot pressing, the two rectangular plates of the auxiliary loading and unloading mechanism can drive the permanent magnet blank to slide downward to the top of the blanking guide plate again, and the permanent magnet blank automatically slides downward into the preset collection container by means of the downwardly inclined blanking guide plate, achieving the effect of automatically blanking the formed permanent magnet blank, eliminating the need for workers to manually pick up and blank the permanent magnet blank, improving the blanking efficiency of the permanent magnet blank, and indirectly improving the forming efficiency of the permanent magnet.

The telescopic end of the telescopic cylinder 11 can drive the moving plate 9 and the extrusion die 10 at its bottom to move up and down inside the box body 1 together.

[0036] As a technical optimization solution of the present invention, the auxiliary loading and unloading mechanism includes two first chutes 12 opened inside the processing table 2. Two first sliders 23 are installed inside each of the two first chutes 12. The tops of the two first sliders 23 are both connected to a moving rod 8 through an electric telescopic rod 24. Two double-headed screws are preset inside each of the two first chutes 12. One ends of the two double-headed screws are both connected to the output end of a preset first driving device, driving the two double-headed screws to rotate inside the corresponding first chutes 12. The first sliders 23 located inside the two first chutes 12 are respectively matched with the outer walls of their corresponding double-headed screws, so that when the double-headed screws rotate, they can drive the two corresponding first sliders 23 to move towards or away from each other.

[0037] As a technical optimization solution of the present invention, second chutes 25 are opened on the outer walls of the two moving rods 8 on the side close to each other. Two second sliders 28 are installed inside each of the two second chutes 25. First rotating plates 26 are rotatably installed at the ends of the two second sliders 28 away from the second chutes 25. Two first linear motors are preset inside each of the two second chutes 25. The two first linear motors can drive the two second sliders 28 to move back and forth inside the corresponding second chutes 25; and two second driving devices are preset inside the two second sliders 28. The output ends of the two second driving devices are respectively connected to the rotating parts of the two first rotating plates 26, so as to be able to drive the two first rotating plates 26 to rotate and adjust.

[0038] As a technical optimization solution of the present invention, second rotating plates 29 are rotatably installed inside each of the two first rotating plates 26. Two third chutes 30 are opened on one side inside each of the two second rotating plates 29. Two third sliders 31 are installed inside each of the two third chutes 30. A rectangular plate 27 is jointly installed at the ends of the two third sliders 31 away from the third chutes 30. Two third driving devices are preset on the outer walls of one side of the two first rotating plates 26. The output ends of the two third driving devices are respectively connected to the rotating parts of the two second rotating plates 29, so as to be able to drive the two second rotating plates 29 to rotate and adjust inside the first rotating plates 26; two second linear motors are preset inside each of the two third chutes 30. The two second linear motors can drive the two third sliders 31 to move up and down inside the corresponding third chutes 30, and then drive the two rectangular plates 27 to move up and down and adjust inside the corresponding second rotating plates 29.

[0039] As a technical optimization solution of the present invention, a sealing door 5 is rotatably installed on the front surface of the box body 1, and a blanking guide plate 6 is rotatably installed on the front surface of the processing table 2. The provided sealing door 5 can seal the box body 1 to ensure that the box body 1 can maintain a vacuum state during use; a first driving device is preset on the front surface of the processing table 2, and the output end of the first driving device is connected to the rotating part of the blanking guide plate 6, so as to drive the blanking guide plate 6 to rotate and adjust.

[0040] As a technical optimization solution of the present invention, two driving lead screws 14 are installed inside the base 3, moving blocks 15 are installed on the outer walls of the two driving lead screws 14, and one end of the two moving blocks 15 close to each other is connected to the outer wall of the protective cover 13. Two second driving devices are preset inside the base 3, and the output ends of the two second driving devices are respectively connected to one end of the two driving lead screws 14, so as to drive the two driving lead screws 14 to rotate inside the base 3 and drive the two moving blocks 15 and the protective cover 13 to move up and down and adjust inside the base 3.

[0041] As a technical optimization solution of the present invention, a heat insulation plate 16 is installed inside the protective cover 13, a driving motor 17 is installed between the heat insulation plate 16 and the protective cover 13, a rotating frame 18 is installed at the output end of the driving motor 17, and the bottom ends of a plurality of heating rods 19 are all connected to the rotating frame 18. The driving motor 17 can drive the rotating frame 18 and a plurality of heating rods 19 to rotate synchronously inside the protective cover 13; the heating rod 19 is an electric heating device with a nickel-chromium alloy electric heating wire inside in the prior art. The nickel-chromium alloy electric heating wire has a high strength in a high-temperature environment, is not easy to deform, has a high emissivity and corrosion resistance; since a heat insulation plate 16 is provided inside the protective cover 13 and a heat insulation material is bonded to the inner wall of the protective cover 13, the high temperature generated by the heating of a plurality of heating rods 19 inside the protective cover 13 will not affect the use of the driving motor 17 and can also reduce heat loss.

[0042] As a technical optimization solution of the present invention, the knocking mechanism includes a plurality of springs 20, and the plurality of springs 20 are all installed on the inner wall of the protective cover 13. A plurality of rotating blocks 21 are rotatably installed on the inner wall of the protective cover 13, and one end of the plurality of springs 20 away from the protective cover 13 is connected to the rotating block 21 close to it. As Figure 7 shown, when the plurality of heating rods 19 rotate counterclockwise inside the protective cover 13, they will squeeze the plurality of rotating blocks 21, thereby driving the plurality of springs 20 to be in a compressed state under pressure. When the heating rod 19 rotates to the position between the two rotating blocks 21, the spring 20 is not stressed and elastically resets, so that the rotating block 21 elastically resets accordingly.

[0043] As a technical optimization solution of the present invention, a plurality of rotating blocks 21 are all equipped with a knocking block 22 at one end away from the rotating part, and the plurality of knocking blocks 22 are all made of high-temperature resistant rubber material. After the plurality of rotating blocks 21 are elastically reset, the knocking blocks 22 are driven to quickly collide with the outer wall of the forming mold 7, so that the forming mold 7 vibrates, and the gap between the metal powders entering the inside of the forming mold 7 is reduced, so that the metal powders can be filled more fully inside the forming mold 7, which is conducive to the subsequent hot pressing of the metal powders; the knocking block 22 is made of high-temperature resistant rubber material, and a high-silicon cloth is bonded to the surface of the knocking block 22, so that the knocking block 22 will not cause damage to the outer wall of the forming mold 7 on the basis of ensuring its own flexibility, avoiding affecting the use of the forming mold 7, and can also have good high-temperature resistance, and will not be affected by the high temperature generated by the heating rod 19.

[0044] In the present invention, when the user uses the device, the sealed door 5 on the front of the box body 1 is opened, and the two first sliders 23 are controlled to move in the corresponding first slide grooves 12 in the direction of approaching each other, driving the two moving rods 8 and other multiple components to move together in the direction of approaching each other on the top of the processing table 2, so that the rectangular plates 27 on the adjacent sides of the two moving rods 8 can all be moved to the top of the forming mold 7, and the outer walls of the adjacent sides of the two rectangular plates 27 are abutted, and then the two second sliders 28 are controlled to move in the corresponding second slide grooves 25 in the direction of approaching the sealed door 5, and the two first rotating plates 26, the second rotating plate 29 and one end of the rectangular plate 27 are driven to move to the upper side of the box body 1. On the outside, the two first rotating plates 26 are controlled to drive the rectangular plates 27 and other components to rotate upward together, so that the ends of the two rectangular plates 27 located outside the box body 1 slowly rotate upward and are in an inclined state, and the lower ends of the two connected rectangular plates 27 are located directly above the forming mold 7. At this time, the two inclined rectangular plates 27 can be used as loading slides. After pouring metal powder into the top of the two rectangular plates 27, it can automatically slide down to the inside of the forming mold 7 for filling, thereby achieving the effect of automatic loading of metal powder, avoiding manual loading, which easily causes metal powder to fall to other positions on the top of the processing table 2, and improving the accuracy of metal powder loading.

[0045] After the metal powder enters the molding die 7, the driving motor 17 can be controlled to start, driving the rotating frame 18 and the plurality of heating rods 19 to rotate synchronously counterclockwise inside the protective cover 13, such as Figure 7As shown, when the multiple heating rods 19 rotate counterclockwise, they will squeeze the multiple rotating blocks 21, thereby driving the multiple springs 20 to be compressed under pressure. When the heating rods 19 rotate to the position between the two rotating blocks 21, the springs 20 are not stressed and elastically reset, causing the rotating blocks 21 to elastically reset and driving the knocking blocks 22 to quickly impact the outer wall of the forming die 7, causing the forming die 7 to vibrate, prompting the gaps between the metal powders entering the interior of the forming die 7 to narrow, so that the metal powders can be filled more fully inside the forming die 7. The staff can continue to add some metal powders into the interior of the forming die 7 according to the height of the metal powders inside the forming die 7, so that the interior of the forming die 7 can be filled with sufficient metal powders, which is beneficial to the subsequent hot pressing of the metal powders and avoids the situation that the gaps between the metal powders inside the forming die 7 are too large, resulting in poor forming quality of the subsequent hot-pressed components.

[0046] Moreover, since the top of the forming die 7 is provided with an inclined surface that slopes downward, when a small amount of metal powders enter the interior of the forming die 7, they will disperse on the top of the forming die 7. As the knocking mechanism inside the protective cover 13 vibrates and knocks the forming die 7, the small amount of metal powders located at the top of the inclined surface can slide downward to the lower end and into the interior of the forming die 7 after being vibrated, reducing the waste of this part of the metal powders.

[0047] After the knocking mechanism vibrates and knocks the forming die 7 to prompt the metal powders inside the forming die 7 to be filled more fully, after the first rotating plate 26, the moving rod 8 and other multiple parts that control the above-mentioned movement and rotation are reset on the top of the processing table 2, by closing the sealing door 5, the heating equipment preset inside the processing table 2 is controlled to start, so that the temperature inside the forming die 7 rises, and the forming die 7 and the metal powders inside it are preheated. Then, the vacuum extraction equipment preset outside the box body 1 is controlled to start, so that the interior of the box body 1 is in a vacuum state. After confirming that the vacuum degree inside the box body 1 reaches the set value, the heating temperature of the heating equipment for the forming die 7 is controlled to rise, and at the same time, the telescopic end of the telescopic cylinder 11 is controlled to extend downward, driving the moving plate 9 and the extrusion die 10 to move downward until the extrusion die 10 enters the interior of the forming die 7. Then, the equipment will automatically perform heating and pressurization operations on the metal powders inside the forming die 7 according to the preset parameters, achieving the effect of hot pressing the permanent magnet.

[0048] To ensure that the molding die 7 and the metal powder inside it can reach the high temperature required for molding, at this time, multiple heating rods 19 inside the protective cover 13 can be controlled to be energized to generate high temperature, and two driving lead screws 14 can be controlled to drive the protective cover 13 to move upward. Until the protective cover 13 completely covers one end of the molding die 7 located inside the base 3, at this time, the high temperature generated by the multiple heating rods 19 can assist in heating the molding die 7, ensuring that the metal powder inside the molding die 7 is completely heated, enabling the metal powder inside the molding die 7 to have a fast heating rate and more uniform heating, which is convenient for preparing high-performance permanent magnets.

[0049] At the same time, the step of driving the protective cover 13 to move upward by the two driving lead screws 14 is also applicable to the step of the above-mentioned knocking mechanism vibrating and knocking the outer wall of the molding die 7. When the protective cover 13 is driven by the two driving lead screws 14 to move up and down, it can synchronously drive the knocking mechanism to perform vibration knocking treatment on different positions of the molding die 7, so as to ensure that the metal powder is more fully filled inside the molding die 7.

[0050] After the metal powder inside the forming die 7 is hot-pressed and formed, the vacuum state inside the control box 1 is released, so that the pressure inside the box 1 gradually returns to the same state as outside the box 1. By controlling the opening of the sealing door 5, with the help of the ejection mechanism preset inside the forming die 7, the formed permanent magnet blank is automatically ejected upward from the inside of the forming die 7. At this time, two second rotating plates 29 can be controlled to rotate downward inside the corresponding first rotating plates 26, driving the close ends of the two rectangular plates 27 to rotate downward together until they abut against the top of the processing table 2. As the two moving rods 8 are controlled to move towards each other, the two rectangular plates 27 are driven to move to the bottom of the permanent magnet blank located at the top of the forming die 7 at this time, and the bottom end of the permanent magnet blank is shoveled. As the ejection mechanism moves downward and resets, the permanent magnet blank then falls onto the tops of the two rectangular plates 27. After controlling the downward sloping guide plate 6 on the front of the processing table 2 to rotate upward to an inclined state, the two second sliders 28 are controlled to drive multiple components such as the two rectangular plates 27 to move towards the downward sloping guide plate 6 in the corresponding second sliding grooves 25, and the telescopic ends of multiple electric telescopic rods 24 are controlled to extend upward together, driving the height of the two rectangular plates 27 to rise. Then, the two first rotating plates 26 can be controlled to rotate downward slowly together, and the two rectangular plates 27 are controlled to move upward slowly inside the corresponding second rotating plates 29 until the two rectangular plates 27 move upward to a position flush with the tops of the second rotating plates 29. At this time, the two rectangular plates 27 can be used as blanking slides, so that the permanent magnet blanks placed on the tops of the two rectangular plates 27 slide downward onto the top of the downward sloping guide plate 6, and automatically slide downward into the preset collection container along the downward sloping guide plate 6, achieving the effect of automatically blanking the formed permanent magnet blanks, eliminating the need for workers to manually pick up and blank the permanent magnet blanks, improving the blanking efficiency of the permanent magnet blanks, and indirectly improving the forming efficiency of the permanent magnets.

[0051] After the above-mentioned permanent magnet blank is ejected upward by the ejection mechanism inside the forming die 7, the telescopic ends of multiple electric telescopic rods 24 can be controlled to extend upward together, pushing the two moving rods 8 to move upward together. The two second rotating plates 29 are controlled to rotate 180 degrees together inside the corresponding first rotating plates 26, driving the vertical sides of the two second rotating plates 29 to rotate to a position away from the first rotating plates 26. The two moving rods 8 are controlled to move towards each other, and the vertical sides of the two second rotating plates 29 are driven to squeeze the formed permanent magnet blank to test whether the strength of the hot-pressed and formed permanent magnet blank meets the standard. With the help of the telescopic adjustment of the telescopic ends of multiple electric telescopic rods 24, the two second rotating plates 29 are driven to squeeze and test different positions of the permanent magnet blank, further improving the comprehensiveness of the strength test of the permanent magnet blank, facilitating the real-time detection of the quality of the formed permanent magnet blank, and thus improving the applicability of the device.
