[0007] According to the above technical solution, the pulley frame is arranged at the bottom of the hollow tube, and a No. 1 spring is arranged between the trapezoidal slider and the heat treatment tank.

[0008] According to the above technical solution, a heat recovery device and a heat control device are provided on the hollow tube, and the heat recovery device includes a sliding plate, a spiral rod, a spiral ring and an activated carbon plate.

When the hollow tube moves downward, the sealing circular plate will squeeze the air inside the hollow tube and spray it out from the one-way air outlet.

[0010] According to the above technical solution, a No. 2 spring is provided between the sliding plate and the heat treatment tank.

[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. The air inside the hollow tube is squeezed by the sealing circular plate, and the spiral seat is squeezed to rotate through the spiral long rod.

[0013] According to the above technical solution, a plurality of holes are opened on the surface of the perforated circular plate, and a No. 3 spring is arranged between the slide groove and the sliding triangle plate. When the sliding triangle plate is separated from the pulley seat, the elastic force of the No. 3 spring itself will drive the sliding triangle plate to reset.

[0014] The present invention provides a device for heat treatment and forming of amorphous and nanocrystalline magnetic cores. It has the following beneficial effects:

[0015] (1) In this invention, the fixed block is limited by the reset of the trapezoidal slider. By limiting the fixed block with the trapezoidal slider, there is no need to push the sliding door with hands all the time, which makes the operation more convenient. After limiting, the amorphous 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, and then the resistance heating plate is heated. The resistance heating plate can control the temperature in multiple stages to control the temperature inside the heat treatment tank and ensure consistent temperature.

[0016] (2) This invention allows the magnetic core to continuously change position during the heating process by rotating the placement rack, thereby eliminating the 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. The reciprocating movement of the pulley rack up and down pushes the hollow tube and the placement rack up and down. The heating by the up and down movement of the placement rack ensures that the magnetic core receives a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.

[0017] (3) This invention uses the activated carbon plate to rotate and adsorb harmful gases generated by high temperature, so that the adsorption surface of the activated carbon is evenly used, avoiding the saturation phenomenon caused by excessive adsorption at a single position. At the same time, the position of the sealing circular plate remains unchanged while the hollow tube moves upward, and a relatively low-pressure state is formed inside the hollow tube. At the same time, the heat at the top of the 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 and ejects it from the one-way air outlet. By pouring the heat from the top to the middle and bottom of the heat treatment tank, heat is prevented from accumulating at the top, resulting in a large temperature difference between the top and the bottom during heating, which affects the heat treatment effect.

[0018] (4) This invention squeezes the air inside the hollow tube through the sealing circular plate and squeezes the spiral seat to rotate through the spiral long rod. The rotation of the spiral seat drives the perforated circular plate to rotate. The rotation of the perforated circular plate drives the perforated ring to rotate. The rotation of the perforated ring drives the hole to rotate. When the hole coincides with the one-way air outlet, the air inside the hollow tube will be discharged from the one-way air outlet. By intermittently introducing heat from the top to the bottom, it can avoid excessive temperature gradients during the heat treatment process and ensure that the temperature is gradually evenly distributed. At the same time, the upward movement of the sliding triangular plate will drive the filter plate to move upward. The filter plate can effectively prevent impurities from sticking to the one-way air outlet and blocking it, thereby affecting the heat conduction effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

A reciprocating screw 8 is fixedly installed on the output end of the moving device 7, an elastic telescopic rod 9 is fixedly installed on the top of the reciprocating screw 8, a hollow tube 10 is fixedly installed on the free end of the elastic telescopic rod 9, a placement rack 11 is fixedly installed on the surface of the hollow tube 10, a movable rack 12 is threadedly installed on the surface of the reciprocating screw 8, a fixed rod 13 is fixedly installed on the bottom of the heat treatment tank 1, the fixed rod 13 passes through the surface of the movable rack 12, and a pulley rack 14 is fixedly installed on the top of the movable rack 12. The placement rack 11 is moved up and down for heating to ensure that the magnetic core obtains a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.

[0029] The pulley frame 14 is set at the bottom of the hollow tube 10, and a spring No. 1 is set between the trapezoidal slider 5 and the heat treatment tank 1. When the trapezoidal slider 5 is separated from the fixed block 4, the elastic force of the spring No. 1 itself will drive the trapezoidal slider 5 to reset.

[0030] When this embodiment is working: by pushing the sliding door 3 upward, the sliding door 3 will drive the fixed block 4 to move upward, and the fixed block 4 will contact the trapezoidal slider 5 when it moves upward, and the fixed block 4 will push the trapezoidal slider 5 to move in the direction away from the fixed block 4. When the fixed block 4 is disengaged from the trapezoidal slider 5, the elastic force of the No. 1 spring will drive the trapezoidal slider 5 to reset, and the reset of the trapezoidal slider 5 will form a limit for the fixed block 4. The trapezoidal slider 5 forms a limit for the fixed block 4, and there is no need to push the sliding door 3 with hands all the time, which makes the operation more convenient. After limiting, the amorphous nanocrystalline magnetic core is placed in the placement rack 11, and then the trapezoidal slider 5 is pushed to release the limit on the fixed block 4, so that the sliding door 3 seals the heat treatment tank 1, and then the resistance heating plate 6 is heated.

At the same time, the driving device 7 is started to drive the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 will drive the elastic telescopic rod 9, the hollow tube 10 and the placement rack 11 to rotate. The rotation of the placement rack 11 can make the magnetic core 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. At the same time, the rotation of the reciprocating screw 8 will drive the movable rack 12 to move up and down along the fixed rod 13. The movable rack 12 moves up and down along the fixed rod 13, which will drive the pulley rack 14 to move up and down. The up and down reciprocating movement of the pulley rack 14 will push the hollow tube 10 and the placement rack 11 to move up and down. The heating by the up and down movement of the placement rack 11 ensures that the magnetic core obtains a suitable heat treatment process, thereby obtaining better magnetic properties and a longer service life.

[0033] A No. 2 spring is provided between the sliding plate 151 and the heat treatment tank 1 . When the sliding plate 151 is separated from the hollow tube 10 , the No. 2 spring will drive the sliding plate 151 to reset, and the sealing circular plate 156 will contact the inner wall of the hollow tube 10 .
