[0004] In the above patent, by providing a through hole, a sandwich layer, a gate plate, and a cover body, it is possible to effectively realize two different heat treatment methods without removing the nanocrystalline magnetic core from the heating furnace, which is beneficial to simplifying the heat treatment forming process of the nanocrystalline magnetic core. However, during the heating process, there may be a temperature difference between the upper and lower parts inside the main body, resulting in inconsistent magnetic properties. This non-uniformity will affect the quality of the final product, making the performance indicators such as the magnetic permeability and magnetic saturation of the magnetic core unstable. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a heat treatment forming device for amorphous and nanocrystalline magnetic cores, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A heat treatment forming device for amorphous nanocrystalline magnetic cores, comprising: a heat treatment tank, a purification device, the purification device is arranged on the top of the heat treatment tank, and the purification device is used to purify harmful gases generated by high temperature; a sliding door, the sliding door is slidably installed on the surface of the heat treatment tank; a fixed block, the fixed block is fixedly installed on the surface of the sliding door; a trapezoidal slider, the trapezoidal slider is slidably installed on the surface of the heat treatment tank; a resistance heating plate, the resistance heating plate is fixedly installed on the inner wall of the heat treatment tank; a driving device is fixedly installed at the bottom of the heat treatment tank, a reciprocating screw rod is fixedly installed at the output end of the driving device, an elastic telescopic rod is fixedly installed at the top of the reciprocating screw rod, a hollow tube is fixedly installed at the free end of the elastic telescopic rod, a placement rack is fixedly installed on the surface of the hollow tube, a moving rack is threadedly installed on the surface of the reciprocating screw rod, a fixed rod is fixedly installed at the bottom of the heat treatment tank, the fixed rod penetrates through the surface of the moving rack, a pulley rack is fixedly installed at the top of the moving rack, when the reciprocating screw rod rotates, it will drive the moving rack to move up and down reciprocally along the fixed rod, the moving rack moving up and down reciprocally along the fixed rod will drive the pulley rack to move up and down reciprocally, and the pulley rack moving up and down reciprocally will push the hollow tube and the placement rack to move up and down reciprocally.

[0007] According to the above technical solution, the pulley rack is arranged at the bottom of the hollow tube, and a first spring is arranged between the trapezoidal slider and the heat treatment tank. When the trapezoidal slider is separated from the fixed block, the elastic force of the first spring itself will drive the trapezoidal slider to reset.

[0008] According to the above technical solution, a heat recovery device and a heat control device are arranged on the hollow tube. The heat recovery device includes a sliding plate, a spiral rod, a spiral ring and an activated carbon plate. During the upward movement of the hollow tube, it will push the sliding plate to move upward, the upward movement of the sliding plate will drive the spiral rod to move upward, and while the spiral rod moves upward, it will squeeze the spiral ring to rotate along the spiral rod, and the rotation of the spiral ring will drive the activated carbon plate to rotate. The sliding plate is slidably installed on the inner wall of the heat treatment tank, the spiral rod is fixedly installed at the top of the hollow tube, the activated carbon plate is rotatably installed at the bottom of the purification device, the spiral ring is fixedly installed at the bottom of the activated carbon plate, and the spiral ring is threadedly installed on the surface of the spiral rod.

[0009] According to the above technical solution, a long rod is fixedly installed at the fixed end of the elastic telescopic rod, a sealing circular plate is fixedly installed at the top of the long rod, a one-way air inlet is arranged on the surface of the hollow tube, and a one-way air outlet is arranged on the surface of the hollow tube. The heat at the top of the inner wall of the heat treatment tank will enter the interior of the hollow tube through the one-way air inlet. When the hollow tube moves downward, the sealing circular plate will squeeze the air inside the hollow tube to spray out from the one-way air outlet.

[0010] According to the above technical solution, a second spring is provided between the sliding plate and the heat treatment tank. After the sliding plate is separated from the hollow tube, the second spring will drive the sliding plate to reset, and the sealing circular plate contacts the inner wall of the hollow tube.

[0011] According to the above technical solution, the heat control device includes a spiral long rod, a perforated circular plate, a perforated ring and a spiral seat. While the sealing circular plate squeezes the air inside the hollow tube, it will squeeze the spiral seat to rotate through the spiral long rod. The rotation of the spiral seat will drive the perforated circular plate to rotate. The rotation of the perforated circular plate will drive the perforated ring to rotate. The rotation of the perforated ring will drive the holes to rotate. The spiral long rod is fixedly installed on the top of the sealing circular plate. The perforated circular plate is rotatably installed on the inner wall of the hollow tube. The perforated ring is fixedly installed on the top of the perforated circular plate. The spiral seat is threadedly installed on the surface of the spiral long rod. The spiral seat is fixedly installed on the top of the perforated circular plate.

[0012] According to the above technical solution, a pulley seat is fixedly installed on the top of the perforated ring. A sliding groove is provided on the inner wall of the hollow tube. A sliding triangular plate is slidably installed on the inner wall of the sliding groove. A filter plate is fixedly installed on the surface of the sliding triangular plate. The filter plate contacts the surface of the one-way air outlet. While the perforated ring rotates, it will drive the pulley seat to rotate. During the rotation of the pulley seat, it will contact the sliding triangular plate. During the rotation of the pulley seat, it will push the sliding triangular plate to move upward. The upward movement of the sliding triangular plate will drive the filter plate to move upward.

[0013] According to the above technical solution, a plurality of holes are provided on the surface of the perforated circular plate. A third spring is provided between the sliding groove and the sliding triangular plate. After the sliding triangular plate is separated from the pulley seat, the elastic force of the third spring itself will drive the sliding triangular plate to reset.

[0014] The present invention provides a non-crystalline nanocrystalline magnetic core heat treatment forming device. It has the following beneficial effects: (1) In this invention, the reset of the trapezoidal slider will limit the fixed block. By limiting the fixed block through the trapezoidal slider, it is not necessary to always push the sliding door by hand, and the operation is more convenient. After the limit, the non-crystalline nanocrystalline magnetic core is placed in the placement rack, and then the trapezoidal slider is pushed to release the limit on the fixed block, so that the sliding door seals the heat treatment tank. Then, the resistance heating plate is heated. The resistance heating plate can control the temperature in multiple segments to control the temperature inside the heat treatment tank and ensure the temperature is consistent.

[0015] (2) In this invention, by rotating the placement rack, the magnetic core can continuously change its position during the heating process, so there is no need for frequent manual operation or adjustment. The automated heating process improves production efficiency, can process more magnetic cores in a shorter time, and reduces manual intervention. By the reciprocating movement of the pulley frame up and down, it will push the hollow tube and the placement rack to move up and down reciprocally. By heating with the placement rack moving up and down, it ensures that the magnetic core obtains a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.

[0016] (3) In this invention, harmful gases generated at high temperatures are adsorbed by the rotation of the activated carbon plate, enabling the adsorption surface of the activated carbon to be evenly used, avoiding the saturation phenomenon caused by excessive adsorption at a single position. At the same time, while the hollow tube moves upward, the position of the sealing circular plate remains unchanged, creating a relatively low-pressure state inside the hollow tube. Meanwhile, the heat at the top inner wall of the heat treatment tank enters the hollow tube through the one-way air inlet. When the hollow tube moves downward, the sealing circular plate squeezes the air inside the hollow tube to be ejected from the one-way air outlet. By pouring the heat at the top into the middle and bottom of the heat treatment tank, heat accumulation at the top is prevented, which could otherwise cause too large a temperature difference between the top and bottom during heating and affect the heat treatment effect.

[0017] (4) In this invention, when the sealing circular plate squeezes the air inside the hollow tube, it also squeezes the spiral base to rotate through the spiral long rod. The rotation of the spiral base drives the rotation of the perforated circular plate, the rotation of the perforated circular plate drives the rotation of the perforated ring, and the rotation of the perforated ring drives the rotation of the holes. When the holes coincide with the one-way air outlet, the air inside the hollow tube is discharged from the one-way air outlet. By intermittently introducing heat from the top to the bottom, a large temperature gradient during the heat treatment process can be avoided, ensuring a gradually uniform temperature distribution. At the same time, when the sliding triangular plate moves upward, it drives the filter plate to move upward. The filter plate can effectively prevent impurities from adhering and blocking the one-way air outlet, thus affecting the heat conduction effect. Description of the Drawings

Specific implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4 , an embodiment of the present invention is: a non-crystalline nanocrystalline magnetic core heat treatment and forming device, including: a heat treatment tank 1, a purification device 2, the purification device 2 is arranged on the top of the heat treatment tank 1, and the purification device 2 is used to purify harmful gases generated by high temperature; a sliding door 3, the sliding door 3 is slidably installed on the surface of the heat treatment tank 1; a fixing block 4, the fixing block 4 is fixedly installed on the surface of the sliding door 3; a trapezoidal slider 5, the trapezoidal slider 5 is slidably installed on the surface of the heat treatment tank 1; a resistance heating plate 6, the resistance heating plate 6 is fixedly installed on the inner wall of the heat treatment tank 1; a driving device 7 is fixedly installed at the bottom of the heat treatment tank 1, the output end of the driving device 7 is fixedly installed with a reciprocating lead screw 8, the top of the reciprocating lead screw 8 is fixedly installed with an elastic telescopic rod 9, the free end of the elastic telescopic rod 9 is fixedly installed with a hollow tube 10, a placement rack 11 is fixedly installed on the surface of the hollow tube 10, a moving rack 12 is threadedly installed on the surface of the reciprocating lead screw 8, a fixing rod 13 is fixedly installed at the bottom of the heat treatment tank 1, the fixing rod 13 penetrates through the surface of the moving rack 12, and a pulley rack 14 is fixedly installed on the top of the moving rack 12. By moving the placement rack 11 up and down for heating, it is ensured that the magnetic core obtains a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.

[0022] The pulley rack 14 is arranged at the bottom of the hollow tube 10, and a first spring is arranged between the trapezoidal slider 5 and the heat treatment tank 1. When the trapezoidal slider 5 is separated from the fixing block 4, the elastic force of the first spring itself will drive the trapezoidal slider 5 to reset.

[0023] During the operation of this embodiment: By pushing the sliding door 3 upward, the upward movement of the sliding door 3 will drive the fixed block 4 to move upward. The upward movement of the fixed block 4 will contact the trapezoidal slider 5, and the fixed block 4 will push the trapezoidal slider 5 to move away from the fixed block 4. When the fixed block 4 is separated from the trapezoidal slider 5, the elastic force of the first spring will drive the trapezoidal slider 5 to reset. The reset of the trapezoidal slider 5 will limit the fixed block 4. By limiting the fixed block 4 through the trapezoidal slider 5, it is not necessary to keep pushing the sliding door 3 by hand, and the operation is more convenient. After the limitation, the amorphous nanocrystalline magnetic core is placed in the placement rack 11. Then, the trapezoidal slider 5 is pushed to release the limitation on the fixed block 4, so that the sliding door 3 seals the heat treatment tank 1. Subsequently, the resistance heating plate 6 is heated. The resistance heating plate 6 can perform multi-stage temperature control to control the temperature inside the heat treatment tank 1 to ensure consistent temperature. At the same time, the driving device 7 is started to drive the reciprocating lead screw 8 to rotate. The rotation of the reciprocating lead screw 8 will drive the elastic telescopic rod 9, the hollow tube 10 and the placement rack 11 to rotate. By rotating the placement rack 11, the magnetic core can continuously change its position during the heating process, so that frequent manual operations or adjustments are not required. The automated heating process improves production efficiency, can process more magnetic cores in a shorter time, reduces manual intervention. At the same time, when the reciprocating lead screw 8 rotates, it will drive the moving frame 12 to reciprocate up and down along the fixed rod 13. The reciprocating up and down movement of the moving frame 12 along the fixed rod 13 will drive the pulley frame 14 to reciprocate up and down. The reciprocating up and down movement of the pulley frame 14 will push the hollow tube 10 and the placement rack 11 to reciprocate up and down. By heating with the up and down movement of the placement rack 11, it is ensured that the magnetic core obtains a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.
