Description

Technical Field

[0001] This invention belongs to the field of nanocrystalline soft magnetic material preparation, specifically relating to a device for preparing nanocrystalline soft magnetic alloys with low magnetic permeability. Background Technology

[0002] Nanocrystalline soft magnetic materials are a new type of soft magnetic material. Amorphous strips obtained by melt quenching (roller method) will begin to crystallize if heated above their crystallization temperature and held for a period of time (this heat treatment is called annealing), and the internal structure will transform from amorphous to crystalline. When preparing nanocrystalline soft magnetic alloys, the raw materials need to be proportioned. In general, the raw materials are manually taken out and weighed, which makes the proportioning efficiency low. When using a machine to proportion the raw materials, the poured-out raw materials are usually weighed. However, there is a certain distance between the platform scale and the raw material container, which can easily lead to the pouring out of more raw materials than needed, thus affecting the proportioning of the raw materials for nanocrystalline soft magnetic alloys. Summary of the Invention

[0003] In order to solve the above problems, the present invention provides a device for preparing nanocrystalline soft magnetic alloys with low magnetic permeability.

[0004] The present invention achieves the above objectives through the following technical solution: it enables more precise weighing of nanocrystalline soft magnetic alloy raw materials during the preparation of nanocrystalline soft magnetic alloys.

[0005] A device for preparing low-permeability nanocrystalline soft magnetic alloys includes two sets of support frames, arranged vertically. A cover plate is mounted above each support frame, forming an angle with the support frame. A preparation chamber is fixedly installed between the two sets of support frames, with its opening facing upwards. A mixing mechanism is installed inside the preparation chamber to mix the raw materials within. A raw material container is positioned between the two sets of support frames. A mounting plate is positioned between the raw material container and the preparation chamber. A driving component is mounted on the mounting plate, driving the mounting plate to rotate the raw material container around the preparation chamber. Two sets of first clamping plates are slidably mounted on the mounting plate, parallel to the length direction of the raw material container. An adjusting component is positioned between the first clamping plates and the mounting plate, adjusting the position of the first clamping plates on the mounting plate. The first clamping plates are rotatably connected to the second clamping plates via a connecting plate. The second clamping plate contacts the outer wall of the raw material container. The connecting plate is inclined. A torsion spring is positioned between the connecting plate and the first clamping plates. A circular scale is positioned between the mounting plate and the raw material container, contacting the raw material container.

[0006] As a further optimization of the present invention, the adjustment component includes a slide groove, a first spring and a slider. The slide groove is opened on the side of the mounting plate near the raw material barrel. The raw material barrel slides inside the slide groove along the length direction of the mounting plate. The first spring connects the slider and the first clamping plate. The slider is set vertically and moves up and down inside the slide groove.

[0007] As a further optimization of the present invention, the driving component includes a mounting frame, which is disposed between one set of support frames and the preparation chamber.

The fixing plate is installed below the cover plate and is in contact with the upper end of the first clamping plate.

[0009] As a further optimization of the present invention, the fixing plate is generally arc-shaped, and the lower surface of the fixing plate is arc-shaped. The middle position of the lower end of the fixing plate is lower than the two ends. The sliding groove is inclined, and the bottom surfaces of the two sets of sliding grooves are combined in a V-shape. The sliding groove and the fixing plate cooperate with each other.

[0010] As a further optimization of the present invention, the mixing mechanism includes a first shaft and a second shaft, which are disposed inside the preparation chamber. The axial directions of the first shaft and the second shaft are parallel to the length direction of the preparation chamber. The first shaft and the second shaft are both U-shaped and parallel to each other. One end of the first shaft and the second shaft is provided with a rotating structure, which drives the first shaft and the second shaft to rotate alternately.

[0011] As a further optimization of the present invention, the rotating structure includes a first gear and a second gear, the first gear being sleeved outside the first shaft and the second gear being sleeved outside the second shaft, and the first gear and the second gear meshing with each other.

[0012] As a further optimization of the present invention, the rotating structure also includes a motor, the axis of which is parallel to the axis of the first shaft, and the output end of the motor is fixedly connected to the first shaft.

At the same time, the taken out raw materials can be mixed, which is beneficial to improving the efficiency of nanocrystalline soft magnetic alloy preparation. Attached Figure Description

Rotation: Two sets of first clamping plates 105 are slidably mounted on the mounting plate 104. The length direction of the first clamping plates 105 and the raw material barrel 103 is parallel. An adjustment component is provided between the first clamping plates 105 and the mounting plate 104. The adjustment component adjusts the position of the first clamping plates 105 on the mounting plate 104. The first clamping plates 105 are rotatably connected to the second clamping plates 106 via the connecting plate 107. The second clamping plates 106 are in contact with the outer wall of the raw material barrel 103. The connecting plate 107 is inclined. A torsion spring 108 is provided between the connecting plate 107 and the first clamping plates 105. A platform scale 109 is provided between the mounting plate 104 and the raw material barrel 103. The platform scale 109 is circular and is in contact with the raw material barrel 103.

[0026] The adjustment assembly includes a slide 201, a first spring 202, and a slider 203. The slide 201 is located on the side of the mounting plate 104 near the raw material barrel 103. The raw material barrel 103 slides inside the slide 201 along the length of the mounting plate 104. The first spring 202 connects the slider 203 and the first clamping plate 105. The slider 203 is vertically positioned and moves up and down inside the slide 201.

[0027] The driving component includes a mounting frame 301, which is disposed between one of the support frames 1 and the preparation chamber 102. The mounting frame 301 is vertically arranged, and the center point of the mounting frame 301 and the center point of the preparation chamber 102 are at the same position. A lifting component is provided on the mounting frame 301, which drives the mounting plate 104 to rise and fall.

[0028] The lifting assembly includes a slide rod 302, a second spring 303, and a fixing plate 304. The slide rod 302 is inserted into the mounting bracket 301 and is radially oriented. The slide rod 302 and the mounting plate 104 are slidably connected. The second spring 303 is sleeved on the outside of the slide rod 302 and is connected to the mounting plate 104. The fixing plate 304 is installed below the cover plate 101 and is in contact with the upper end of the first clamping plate 105.

[0029] The fixing plate 304 is generally arc-shaped, and the lower surface of the fixing plate 304 is arc-shaped. The middle position of the lower end of the fixing plate 304 is lower than the two ends. The slide groove 201 is inclined. The bottom surfaces of the two sets of slide grooves 201 are combined in a V-shape and inclined. The slide groove 201 and the fixing plate 304 cooperate with each other.

[0030] The mixing mechanism includes a first shaft 601 and a second shaft 602, which are disposed inside the preparation chamber 102. The axial directions of the first shaft 601 and the second shaft 602 are parallel to the length direction of the preparation chamber 102. The first shaft 601 and the second shaft 602 are both U-shaped and parallel to each other. One end of the first shaft 601 and the second shaft 602 is provided with a rotating structure, which drives the first shaft 601 and the second shaft 602 to rotate alternately.

[0031] The rotating structure includes a first gear 701 and a second gear 702. The first gear 701 is sleeved on the outside of the first shaft 601, and the second gear 702 is sleeved on the outside of the second shaft 602. The first gear 701 and the second gear 702 mesh with each other.

[0032] The rotating structure also includes a motor 801, the axis of which is parallel to the axis of the first shaft 601, and the output end of the motor 801 is fixedly connected to the first shaft 601.

[0033] The raw material barrel 103 has a first discharge port 401 at one end near the preparation chamber 102. The center of the first discharge port 401 is at the same position as the center of the platform scale 109. A rod 403 is fixedly installed inside the raw material barrel 103. The rod 403 is parallel to the length direction of the raw material barrel 103. A baffle 402 is slidably sleeved on the outside of the rod 403. The baffle 402 completely covers the first discharge port 401. The rod 403 is made of rubber.

[0034] The mounting plate 104 has a second discharge port 501 within the range of the first discharge port 401. A trigger 502 is threaded through the inside of the mounting plate 104. The trigger 502 is in contact with the first shaft 601 and the second shaft 602. A third spring 503 is sleeved on the outside of the trigger 502. The third spring 503 is located inside the mounting plate 104. A scraper 504 is slidably mounted on the outer surface of the trigger 502. The scraper 504 is rotatably connected to the upper end of the mounting plate 104.

[0035] The process flow of the device proposed in this embodiment is as follows:

[0036] The two sets of first clamping plates 105 are pushed away from each other. With the cooperation of the slider 203, the first spring 202 is compressed and deformed, and the raw material barrel 103 containing the raw material is placed between the two sets of first clamping plates 105. Under the elastic force of the first spring 202, the two sets of first clamping plates 105 move closer to each other. The first clamping plates 105 drive the second clamping plates 106 to move closer to each other. After the second clamping plates 106 contact the raw material barrel 103, the two sets of first clamping plates 105 continue to move closer to each other. Under the action of the connecting plate 107, the second clamping plates 106 drive the raw material barrel 103 to move upward, so that there is a gap between the raw material barrel 103 and the mounting plate 104, thereby fixing the raw material barrel 103 on the mounting plate 104.

[0037] Rotate the mounting bracket 301 so that the raw material barrel 103 can be moved directly above the preparation chamber 102. During the movement, the first clamping plate 105 comes into contact with the fixing plate 304. Since the two sets of sliding grooves 201 are combined in a figure-eight shape, under the action of the fixing plate 304, the fixing plate 304 pushes the two sets of first clamping plates 105 away from each other along the bottom surface of the sliding grooves 201. Under the action of the connecting plate 107, the first clamping plate 105 drives the two sets of second clamping plates 106 away from each other, so that the second clamping plates 106 are separated from the raw material barrel 103. At this time, the raw material barrel 103 falls above the platform scale 109, and the platform scale 109 can weigh the raw material barrel 103.

[0038] At the same time, the fixing plate 304 continues to push the first clamping plate 105 toward the preparation chamber 102, thereby pushing the mounting plate 104 to slide along the length of the slide bar 302. At this time, the second spring 303 is compressed and deformed.

[0039] Meanwhile, the trigger 502 is located inside the preparation chamber 102. The first shaft 601 and the second shaft 602 can contact the trigger 502, connecting the motor 801 to an external power source. The motor 801 drives the first shaft 601 to rotate. With the cooperation of the first gear 701 and the second gear 702, the first shaft 601 and the second shaft 602 rotate relative to each other, thereby stirring the raw materials falling into the preparation chamber 102 and mixing different raw materials together.

[0040] When the first shaft 601 and the second shaft 602 rotate, they can push the trigger 502 to move upward. At this time, the third spring 503 is compressed and deformed. When the trigger 502 moves upward, it can push the baffle 402 to separate from the inner wall of the raw material barrel 103, so that the raw material inside the raw material barrel 103 falls through the first discharge port 401, passes through the platform scale 109, and falls into the interior of the mixing chamber through the second discharge port 501. Since the trigger 502 and the mounting plate 104 are threadedly connected, the trigger 502 can rotate while lifting and lowering, thereby driving the scraper 504 to rotate. The scraper 504 scrapes the raw material on the surface of the mounting plate 104 into the interior of the second discharge port 501, avoiding waste of raw materials.

[0041] Through the above actions, the present invention can weigh the raw material barrel 103, measure the amount of raw material reduced inside the raw material barrel 103 to determine the amount of raw material to be taken out, and when the appropriate raw material is taken out, the raw material barrel 103 can be closed directly to stop taking out material, making the material taking more accurate, thereby ensuring the proportion of raw materials. At the same time, the taken-out raw materials can be mixed, which is beneficial to improving the efficiency of nanocrystalline soft magnetic alloy preparation.

[0042] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
