Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of electromagnetic technology, in particular to a magnetic conduction device and a magnetizing equipment. BACKGROUND

[0002] Al-Ni-Co permanent magnet material is the earliest widely used permanent magnet material, and its preparation process and technology are relatively mature. Al-Ni-Co permanent magnet material has the performance advantages of low temperature coefficient, good corrosion resistance, and high working temperature, and is currently widely used in instruments and meters, motors and other permanent magnet devices requiring high temperature stability, and is particularly suitable for use in weapons such as torpedoes, missiles, and aircraft, and in spacecraft such as satellites.

[0003] Radiation magnetic ring is a new product developed in recent years, and is another new direction of development of magnetic materials. It has the advantages of good reliability and high precision, and the demand for multi-pole radiation orientation magnetic ring in the market is increasing. Some Al-Ni-Co radiation ring magnets are generally made by first magnetizing individual magnets and then splicing them together. However, such spliced radiation rings have the problems of large error between individual magnets, difficult splicing, and inability to guarantee size precision. In addition, the outer surface of the radiation ring in the radial direction is N-pole (or S-pole), and the inner surface in the radial direction is S-pole (or N-pole), so it cannot be magnetized using ordinary magnetic conduction devices.

[0004] Currently, there are some ways to magnetize radiation magnetic rings using an external magnetic field, such as N-S method and N-N (or S-S) method. The N-S magnetizing method has a relatively simple structure, and the pole head magnetic conduction structure on one side is moved to center the magnet on the other side. However, the magnet installation space is small, and the operation is not convenient. The N-N (or S-S) magnetizing method sets a pole head on both sides of the magnet, and then symmetrically introduces the magnetic field of the two pole heads to the magnet in the middle. However, it is difficult to ensure that the centers of the two pole heads are consistent, resulting in uneven magnetic field at the middle and edge positions of the magnetic ring, which greatly affects the magnetizing effect. SUMMARY

[0005] Therefore, it is necessary to provide a magnetic conduction device and a magnetizing equipment to solve the problem of uniform magnetization of radiation magnetic rings.

[0006] The magnetic conduction device provided by the present disclosure includes a first magnetic conduction body and a second magnetic conduction body oppositely arranged along a first direction; a first mounting portion fixed to one side of the first magnetic conduction body facing the second magnetic conduction body; a second mounting portion fixed to one side of the second magnetic conduction body facing the first magnetic conduction body; and a support structure including a support portion and a first matching portion and a second matching portion oppositely arranged on both sides of the support portion along the first direction, the first matching portion being detachably connected with the first mounting portion, and the second matching portion being detachably connected with the second mounting portion.

[0007] By incorporating a support structure, the magnetic ring to be magnetized can be supported more stably and accurately, and the magnetic field can be guided, resulting in a more concentrated and uniform magnetic field lines. This magnetic guiding device can be used to magnetize magnetic rings. Through the cooperation of the first magnetic guiding body, the second magnetic guiding body, and the support structure, it achieves integrated magnetization, uniform magnetic field, and optimized magnetic field direction. Furthermore, this magnetic guiding device has a simple structure, is easy to install, and is suitable for high-temperature operation.

[0008] In some embodiments, the first magnetically conductive body and the first mounting portion constitute a first magnetically conductive structure, and the second magnetically conductive body and the second mounting portion constitute a second magnetically conductive structure. The first magnetically conductive structure and the second magnetically conductive structure are movable along a first direction to detach the support structure.

[0009] By setting up a first and second magnetically conductive structure that can move relative to each other, the structure of the first and second mounting parts can be simplified, ensuring the installation strength of the support structure. Furthermore, this arrangement also facilitates different mounting postures for the magnetic ring.

[0010] In some embodiments, the first mounting part includes a first lifting block and a first covering block. The first lifting block is fixedly connected to the first magnetically conductive body and lifts the first mating part. The first covering block covers the first mating part. The first covering block, the first lifting block, and the first mating part are used to form a complete magnetically conductive channel. The second mounting part includes a second lifting block and a second covering block. The second lifting block is fixedly connected to the second magnetically conductive body and lifts the second mating part. The second covering block covers the second mating part. The second covering block, the second lifting block, and the second mating part are used to form a complete magnetically conductive channel.

[0011] This configuration allows the support structure to be stably installed on the first and second mounting parts. At the same time, the first and second magnetic conductive bodies can be set to be relatively fixed, which helps to maintain a precise relative position and ensures high centering accuracy of the support structure. In addition, the magnetic field conducted is complete and uniform, and the magnetic conductive device can achieve a good magnetization effect.

[0012] In some embodiments, the first mounting part is annular and sleeved on the cylindrical first mating part, and the second mounting part is annular and sleeved on the cylindrical second mating part.

[0013] This configuration allows the first and second mounting sections to maintain good structural strength and provide accurate and stable support for the supporting structure. The magnetically conductive device can be equipped with multiple supporting structures.

[0014] In some embodiments, the outer diameter of the first mounting portion and the outer diameter of the second mounting portion are less than or equal to the outer diameter of the support portion.

[0015] This setup ensures the correct shape of the guided magnetic lines of force and facilitates the installation and positioning of the magnetic ring.

[0016] Exemplarily, the magnetic conducting device further comprises a first ceramic sleeve and a second ceramic sleeve, the first ceramic sleeve is sleeved on the first mounting portion and is adapted to abut against the first magnetic conducting body, and the second ceramic sleeve is sleeved on the second mounting portion and is adapted to abut against the second magnetic conducting body.

[0017] In this way, the ceramic sleeve can be used to position the magnetic ring to be magnetized in the first direction, ensuring the position accuracy, and the ceramic sleeve can have the characteristics of high temperature resistance and non-magnetic conductivity, ensuring the magnetic conducting effect of the first magnetic conducting body and the second magnetic conducting body.

[0018] In some embodiments, along the first direction, the first magnetic conducting body and the second magnetic conducting body are symmetrically arranged and have the same shape. Exemplarily, the first mounting portion and the second mounting portion are symmetrically arranged and have the same shape.

[0019] In this way, the support structure can be installed in both directions, and accurate and uniform magnetizing magnetic field can be better ensured.

[0020] In some embodiments, the first end of the first magnetic conducting body away from the support portion is larger than the second end of the first magnetic conducting body close to the support portion.

[0021] In this way, the magnetic conducting device can be used to guide the magnetic field on both sides to a smaller area, and accurate and uniform radial magnetic field can be achieved.

[0022] In some embodiments, the material of the first magnetic conducting body, the material of the second magnetic conducting body, the material of the first mounting portion, the material of the second mounting portion, and the material of the support structure comprise the same magnetic conducting material.

[0023] In this way, the magnetic conducting performance of the support structure can be ensured, and the overall magnetic conducting device has good magnetic conducting ability and high magnetic permeability. In addition, it also helps to make the thermal expansion coefficients of the overall magnetic conducting device consistent, ensuring the stability of the shape, the accuracy and uniformity of the guided magnetic field under high temperature.

[0024] The disclosure also provides a magnetizing device, which comprises the aforementioned magnetic conducting device, a first pole head connected with the first magnetic conducting body and used to provide a first magnetic field, and a second pole head connected with the second magnetic conducting body and used to provide a second magnetic field, the polarity of the second magnetic field being the same as that of the first magnetic field.

[0025] The magnetizing device can provide a uniform and stable magnetizing magnetic field by being equipped with the magnetic conducting device. The magnetizing device can provide N-N opposite top magnetizing mode or S-S opposite top magnetizing mode, and can be used to manufacture radiation magnetic rings.

[0026] In some embodiments, the magnetizing device further comprises a heating device for heating or heat preservation of the support structure.

[0027] In this way, the temperature of the magnetic ring can be maintained during long-time magnetization operation, and good magnetization effect can be ensured.

[0028] The disclosure also provides a magnetization method, which comprises: heating a magnetic ring sleeved on a support structure, so that the temperature of the magnetic ring is within a range of 1200-1300 DEG C, wherein the support structure comprises a support part and first and second matching parts oppositely arranged on both sides of the support part along a first direction; cooling the magnetic ring, so that the temperature of the magnetic ring is within a range of 780-830 DEG C; connecting the first matching part to a first mounting part and the second matching part to a second mounting part, so that the magnetic ring is mounted between first and second magnetic conductive bodies oppositely arranged along the first direction, wherein the first mounting part is fixedly connected to the first magnetic conductive body, the second mounting part is fixedly connected to the second magnetic conductive body, the first magnetic conductive body is connected to a first pole head, and the second magnetic conductive body is connected to a second pole head; and magnetizing the magnetic ring by using the first and second pole heads to provide a same-pole magnetic field to the magnetic ring.

[0029] The magnetization method can achieve good shaping of the mechanical properties and magnetism of the magnetic ring, accurately position the high-temperature magnetic ring, and magnetize the magnetic ring well, so that a radiation magnetic ring can be obtained.

[0030] In some embodiments, the magnetizing step comprises: heating or heat-insulating the magnetic ring.

[0031] The method can avoid heat loss of the magnetic ring, and is conducive to achieving good side magnetization effect.

[0032] The disclosure also provides a radiation magnetic ring, which can be manufactured according to the above-described magnetization method.

[0033] The radiation magnetic ring can have an angle, a high strength, and a uniform radiation magnetic field. BRIEF DESCRIPTION OF DRAWINGS

[0052] Referring to Figure 1 ,Figure 1 A magnetic guiding device according to an embodiment of this disclosure is shown. The magnetic guiding device 100 provided in this embodiment includes a first magnetic guiding structure 1, a second magnetic guiding structure 2, and a support structure 3.

[0053] For example, the first magnetically conductive structure 1 includes a first magnetically conductive body 11 and a first mounting portion 12. The second magnetically conductive structure 2 includes a second magnetically conductive body 21 and a second mounting portion 22. In other embodiments, the first magnetically conductive structure 1 consists only of the first magnetically conductive body 11 and the first mounting portion 12; the second magnetically conductive structure 2 consists only of the second magnetically conductive body 21 and the second mounting portion 22, to ensure particularly concentrated and controllable magnetic lines of force, and to ensure a simple and easy-to-operate structure.

[0054] The first magnetically conductive structure 1 and the second magnetically conductive structure 2 are arranged opposite each other along the Z-axis, and they can have symmetrical shapes. For example, the first magnetically conductive body 11 and the second magnetically conductive body 21 have mirror-symmetrical shapes. The first mounting portion 12 and the second mounting portion 22 can be provided according to actual needs. The first mounting portion 12 can be fixed to the end of the first magnetically conductive body 11 facing the second magnetically conductive body 21, i.e., the right side of the second end 102; the second mounting portion 22 can be fixed to the end of the second magnetically conductive body 21 facing the first magnetically conductive body 11, i.e., the left side of the fourth end 202.

[0055] The support structure 3 may include a support portion 31, a first mating portion 32, and a second mating portion 33. The first mating portion 32 and the second mating portion 33 are disposed opposite to each other on both sides of the support portion 31. Figure 1 In the installation configuration shown, the first mating part 32 is located to the left of the support part 31 along the Z-axis, and the second mating part 33 is located to the right of the support part 31 along the Z-axis. The support structure 3 can be made of a magnetic material, and the support structure 3 can be a one-piece structure.

[0056] The first mating part 32 is detachably connected to the first mounting part 12, and the second mating part 33 is detachably connected to the second mounting part 22. The support structure 3 as a whole can be installed into the space formed by the first magnetically conductive body 11 and the second magnetically conductive body 21, and can also be removed from there. The first magnetically conductive body 11 and the second magnetically conductive body 21 can be fixedly installed without obstructing the placement and removal of the support structure 3.

[0057] The magnetic guiding device provided in this embodiment can support a magnetic ring to be magnetized using a support structure, and can transfer the magnetic field transmitted between the first and second magnetic guiding bodies to the magnetic ring to be magnetized. The support structure allows for convenient and accurate installation of the high-temperature magnetic ring, ensuring precise positioning of the magnetic ring relative to the first and second magnetic guiding bodies, and providing a uniform magnetization environment.

[0058] In some embodiments, the first mounting portion 12 comprises a first lifting block 13 and a first cover block 14. The second mounting portion 22 comprises a second lifting block 23 and a second cover block 24. As shown in Figure 1 The first lifting block 13 can be fixedly connected to the first magnetic conduction main body 11, and the two can be an integral structure. The second lifting block 23 can be fixedly connected to the second magnetic conduction main body 21, and the two can be an integral structure. The first lifting block 13 lifts the first matching portion 32, and the second lifting block 23 lifts the second matching portion 33. It can be understood that in some embodiments, the support structure 3 can have a symmetrical structure, and then the first lifting block 13 can be used to lift the second matching portion 33, and the second lifting block 23 can be used to lift the first matching portion 32.

[0059] In combination with Figure 2 As shown, Figure 2 A cross-sectional view at A-A in Figure 1 The first matching portion 32 can be put into the first lifting block 13 along the Y-axis direction, and the first lifting block 13 can also limit the first matching portion 32 along the X-axis direction. The first cover block 14 can cover the first matching portion 32, and the first cover block 14 can also be engaged with the first lifting block 13. As shown in Figure 2 The first cover block 14, the first lifting block 13 and the first matching portion 32 can be precisely matched to form a complete magnetic conduction channel, which can smoothly transmit the magnetic field transmitted by the first magnetic conduction main body 11 to the support portion 31.

[0060] Similarly, the second lifting block 23 can lift the second matching portion 33 along the Y-axis direction, and can also limit the movement trend of the second matching portion 33 along the X-axis direction. The second cover block 24 can cover the second matching portion 33, and the second cover block 24 can be engaged with the second lifting block 23. The second lifting block 23, the second matching portion 33 and the second cover block 24 can be used to form a complete magnetic conduction channel, which can more completely and smoothly transmit the magnetic field transmitted by the second magnetic conduction main body 21 to the support portion 31.

[0061] As shown in Figure 1 And Figure 2 The first mounting portion 12 is annular. The first matching portion 32 is cylindrical. The first mounting portion 12 can be sleeved on the first matching portion 32. The outer periphery of the first mounting portion 12 can be circular. The inner periphery of the first mounting portion 12 can be circular but also can be other shapes, and the first matching portion 32 can be circular or other shapes to match. The circular annular first mounting portion 12 and the circular first matching portion 32 can achieve more uniform conduction in the circumferential direction, but other shape designs can still be selected according to needs. The first lifting block 13 can have a semi-circular annular shape, and the first cover block 14 can have a semi-circular annular shape.

[0062] The second mounting portion 22 and the second matching portion 33 can be symmetrically arranged with the first mounting portion 12 and the first matching portion 32. The second mounting portion 22 is annular and is sleeved on the cylindrical second matching portion 33. The second lifting block 23 can have a semi-circular annular shape, and the second cover block 24 can have a semi-circular annular shape. Exemplarily, the top surface of the first lifting block 13 and the top surface of the second lifting block 23 are arranged substantially parallel to the horizontal plane.

[0063] Exemplarily, the first magnetic conduction main body 11 and the second magnetic conduction main body 21 have the same shape. The first magnetic conduction main body 11 and the second magnetic conduction main body 21 are arranged along the Z-axis direction and are symmetrical, and the symmetry plane can be parallel to the XY plane. The first magnetic conduction main body 11 includes a first end 101 and a second end 102. The second end 102 can be fixedly connected with the first mounting portion 12 and can be used to position the position of the support structure 3 along the Z-axis direction. The projection of the first end 101 on the XY plane is larger than the projection of the second end 102 on the plane, the first magnetic conduction main body 11 can include a circularly smooth transition peripheral surface from the first end 101 to the second end 102, and the radial dimension of the portion located on the right side of any two positions of the first magnetic conduction main body 11 can be less than or equal to the radial dimension of the portion located on the left side. The second magnetic conduction main body 21 includes a third end 201 and a fourth end 202, and at any two positions of the second magnetic conduction main body 21, the radial dimension at the position close to the fourth end 202 can be less than or equal to the radial dimension at the position close to the third end 201. In this way, the magnetic conduction device 100 can ensure that the magnetic field lines guided thereby are concentrated.

[0064] Exemplarily, the outer diameter of the first mounting portion 12 and the outer diameter of the second mounting portion 22 are less than or equal to the outer diameter of the support portion 31. In this way, the magnetic field lines guided by the magnetic conduction device 100 can be concentrated within the range of the support portion 31, and then can be uniformly radiated outward by means of the support portion 31.

[0065] Exemplarily, the material of the first magnetic conduction main body 11 and the material of the second magnetic conduction main body 21 include iron-cobalt-vanadium. The material of the first mounting portion 12, the material of the second mounting portion 22 and the material of the support structure 3 can include a high magnetic conduction material, such as iron-cobalt-vanadium alloy.

Exemplarily, the first magnetic conduction main body 11 is fixedly connected with the first mounting portion 12, and the second magnetic conduction main body 21 is fixedly connected with the second mounting portion 22. The first magnetic conduction main body 11 and the first mounting portion 12 can be used to constitute a first magnetic conduction structure 1, and the second magnetic conduction main body 21 and the second mounting portion 22 can constitute a second magnetic conduction structure 2. The first magnetic conduction structure 1 and the second magnetic conduction structure 2 are movable along the Z-axis direction (i.e. the first direction herein) to separate the support structure 3 from the first magnetic conduction structure 1 and the second magnetic conduction structure 2.

[0067] Optionally, one of the first magnetic conductive structure 1 and the second magnetic conductive structure 2 can be fixed, and only the other one is movable; or both the first magnetic conductive structure 1 and the second magnetic conductive structure 2 can be movable.

[0068] Exemplarily, the first mounting portion 12 is annular, for example, a circular ring. The cross-sectional shape of the outer periphery of the first mounting portion 12 can be circular; the cross-sectional shape of the inner periphery of the first mounting portion 12 can be circular or other shapes. The first mounting portion 12 is sleeved on the cylindrical first fitting portion 32, in other words, the cylindrical first fitting portion 32 is sleeved in the annular first mounting portion 12. Exemplarily, the first fitting portion 32 can be, for example, a circular truncated cone, which has a small head and a large root. The first mounting portion 12 includes a circular truncated cone-shaped counterbore. Exemplarily, the second mounting portion 22 can be symmetrically arranged with the first mounting portion 12, and the second mounting portion 22 can be annular and can be sleeved on the cylindrical second fitting portion 33.

[0069] Exemplarily, the magnetic conductive device 100 further includes a first ceramic sleeve 41 and a second ceramic sleeve 42. The first ceramic sleeve 41 can be sleeved on the first mounting portion 12, and the second ceramic sleeve 42 can be sleeved on the second mounting portion 22. The first ceramic sleeve 41 is adapted to abut against the first magnetic conductive body 11, and the inner hole shape of the first ceramic sleeve 41 can match the outer periphery shape of the first magnetic conductive body 11. The second ceramic sleeve 42 is adapted to abut against the second magnetic conductive body 21. The second ceramic sleeve 42 and the first ceramic sleeve 41 are spaced apart along the Z-axis direction and can be exemplarily symmetrically arranged. The first ceramic sleeve 41 and the second ceramic sleeve 42 can clamp the magnetic ring to be magnetized along the Z-axis direction.

[0070] The material of the first ceramic sleeve 41 and the second ceramic sleeve 42 can include ceramic, and exemplarily can include other high-temperature-resistant and non-magnetic conductive materials. The ceramic material also achieves good wear resistance and rigidity.

[0071] Reference Figure 4 and Figure 5 , Figure 4 The magnetizing device provided by the embodiment of the present disclosure is shown, Figure 5 is Figure 4 the cross-sectional structure at B-B in FIG. 1. When the first mounting portion 12 and the second mounting portion 22 are in a split structure, the first mounting portion 12 and the second mounting portion 22 need to be spliced after the support structure 3 is placed, and then the first ceramic sleeve 41 and the second ceramic sleeve 42 can be assembled. The first ceramic sleeve 41 can be provided with various simple opening and closing structures or bolt structures, or can be hung on the first mounting portion 12 by configuring the center of gravity.

[0072] Reference Figure 6 and Figure 7 , Figure 6 and Figure 7A magnetizing device is shown. The magnetizing device 500 can include the aforementioned magnetic conduction device 100, the first pole head 301 and the second pole head 302.

[0073] The first pole head 301 can be connected with the first magnetic conduction body 11. Exemplarily, the first magnetic conduction body 11 can be welded to the first pole head 301. The first pole head 301 can provide a first magnetic field through its coil (not shown).

[0074] The second pole head 302 can be connected with the second magnetic conduction body 21. The second magnetic conduction body 21 can be welded to the second pole head 302. The second pole head 302 can provide a second magnetic field through its coil (not shown). The second magnetic field has the same polarity as the first magnetic field, for example, to achieve N-N or S-S opposite magnetic field.

[0075] The magnetizing device can be used to magnetize a magnetic ring into a radiation magnetic ring. The magnetic field of the magnetizing device is uniform and accurate in position, and can achieve relatively simple operation in a high-temperature environment.

[0076] Exemplarily, the magnetizing device 500 further includes a heating device (not shown) for heating the support structure 3 or a heat preservation device (not shown) for heat preservation.

[0077] Reference Figure 8 , Figure 8 A process flow of a magnetizing method in the present disclosure is shown. Exemplarily, the aforementioned magnetic conduction device 100 can be used to install and conduct magnetism for the magnetic ring 200. The aforementioned magnetizing device 500 can be used to magnetize the magnetic ring 200. In some embodiments, the magnetizing method 1000 includes the following steps.

[0078] In step S101, the magnetic ring sleeved on the support structure is heated. The temperature of the heated magnetic ring is within the range of 1200-1300°C. The support structure includes a support part and first and second matching parts oppositely arranged on both sides of the support part along a first direction.

[0079] In step S102, the magnetic ring is cooled. The heated magnetic ring can be cooled to a temperature within the range of 780-830°C.

[0080] In step S103, the magnetic ring is installed between the first and second magnetic conduction bodies oppositely arranged along the first direction. Exemplarily, the installation of the magnetic ring can be achieved by connecting the first matching part to the first mounting part and the second matching part to the second mounting part. The first mounting part is fixedly connected to the first magnetic conduction body, and the second mounting part is fixedly connected to the second magnetic conduction body. The first magnetic conduction body is connected to the first pole head, and the second magnetic conduction body is connected to the second pole head.

[0081] In step S104, the magnetic ring is magnetized. The first pole head and the second pole head can be used to provide a same-pole magnetic field to the magnetic ring, and the support structure can be used to conduct the magnetic field to magnetize the magnetic ring. For example, the magnetizing process can include heating or keeping the magnetic ring at a temperature.

[0082] The magnetizing method provided by the embodiments of the present disclosure can adjust the crystal lattice and magnetic properties of the magnetic ring, and can form a radiation magnetic ring with good performance, uniform magnetic field, and high strength.

[0083] For example, the magnetizing method can be based on Figure 6 The magnetizing device 500 shown in FIG. 5 is used to implement the magnetizing method 1000. In the magnetizing device 500, the distance between the first pole head 301 and the second pole head 302 can be set to 300 mm and fixed. The coil diameter of each of the first pole head 301 and the second pole head 302 can be φ230 mm. The support structure 3 can be inserted into the magnetic ring 200 and heated to about 1200 ℃ together, and then air-cooled to about 780 ℃. The support structure 3 and the magnetic ring 200 are installed on the first magnetic conducting structure 1 and the second magnetic conducting structure 2, and the first cover block 14 and the second cover block 24 are covered. The power supply of the magnetizing device 500 is turned on, and a current of 100 A is supplied to the coil, and then the first pole head 301 and the second pole head 302 provide a N-N opposite magnetic field, and the magnetic ring 200 is magnetized by the magnetic conducting device 100. After magnetizing for a proper time, the magnetic conducting device 100 is disassembled and the manufactured radiation magnetic ring is taken out. For example, the magnetic ring 200 can be heated or kept at a temperature for a long time to magnetize.

[0084] Figure 9 FIG. 6 shows the magnetic field lines formed by the magnetizing method provided by the embodiments of the present disclosure, Figure 10 FIG. 7 shows the magnetic induction intensity formed by the magnetizing method provided by the embodiments of the present disclosure. As shown in FIG. 7, the magnetic induction intensity of the magnetic ring 200 is high.

[0085] For comparison, Figure 11 FIG. 8 shows the magnetic field lines formed by the magnetizing method in the comparative embodiments, Figure 12 FIG. 9 shows the magnetic induction intensity formed by the magnetizing method in the comparative embodiments. In the comparative embodiments, because there is no support structure, an air gap is left between the two magnetic conducting columns, so the magnetic field lines have a large slope, are unstable and not uniform, and the magnetic induction intensity is weak. In addition, it is also difficult to quickly and accurately install the high-temperature magnetic ring in the comparative embodiments.
