The second magnetic plate 74 and the first magnetic plate 72 are magnetically repelled from each other. Both sides of the conveying frame 1 are fixedly connected with a first conduit 75. The first conduit 75 is connected to the inner cavity of the driving shaft of the conveying frame 1. The first conduit 75 is away from the conveying frame. One end of the body 1 passes through the cooling box 4 and is fixedly connected with a flow-pushing plate 76, and the flow-pushing plates 76 on both sides are arranged oppositely, and the side walls of the flow-pushing plates 76 are provided with flow-pushing holes 761 at equal intervals, and the side walls of the driving shaft of the conveying frame 1 are provided with pressure flow grooves 77 at equal intervals, and a one-way valve is arranged in the pressure flow groove 77, and the central axis of the pressure flow groove 77 coincides with the central axis of the arc plate 71, and the pressure flow groove 77 and the second magnetic plate 74 are arranged with gaps staggered, the arc plate 71 and the side wall of the driving shaft of the conveying frame 1 are fitted and slid, and the second magnetic plate 74 is concavely arranged on the side wall of the driving shaft of the conveying frame 1;

[0038] The one-way valve disposed in the pressure flow groove 77 can only allow the air flow in the arc plate 71 to flow into the rotating shaft of the conveying frame body 1;

[0039] When the second magnetic plate 74 is separated from the first magnetic plate 72, the inner cavity of the arc plate 71 is connected with the pressure flow groove 77. At this time, the first magnetic plate 72 is reset under the rebound action of the second spring 73, so that the airflow in the inner cavity of the arc plate 71 is pressed into the pressure flow groove 77, thereby opening the one-way valve in the pressure flow groove 77, so that the airflow moves along the inner cavity of the drive shaft to the first conduits 75 on both sides, and finally fills into the quenching water along the push flow holes 761 on the side walls of the push flow plate 76, thereby forming an opposing thrust, so that the quenching water on both sides moves toward the side wall of the aluminum alloy material, so that the quenching water in the cooling box 4 is evenly in contact with the aluminum alloy material, thereby effectively improving the cooling efficiency of the aluminum alloy material.

[0040] Reference Figure 2 , Figure 3 and Figure 4 , wherein the side wall of the arc plate 71 is fixedly connected with a second conduit 78, the side of the second conduit 78 away from the arc plate 71 is connected with the inner cavity of the air flow box 61, and the side wall of the arc plate 71 is fixedly connected with an air supply pipe 79, and both the second conduit 78 and the air supply pipe 79 are provided with a one-way valve, and the one-way valve in the second conduit 78 can only allow the airflow in the inner cavity of the arc plate 71 to enter the air flow box 61; the one-way valve in the air supply pipe 79 can only allow the external airflow to be supplemented into the arc plate 71 when the first magnetic plate 72 is reset;

[0041] Through the arrangement of the above structure, when the second magnetic plate 74 contacts and repels the first magnetic plate 72, the heating box 3 is just in the state of hovering with the air pump 64 turned on. At this time, the first magnetic plate 72 retracts into the arc plate 71, and the one-way valve in the first duct 75 is opened, so that the airflow in the arc plate 71 enters the airflow box 61 along the second duct 78, thereby effectively increasing the airflow impulse formed in the guide hole 62 at the initial stage of hovering, so that the aluminum alloy material is quickly lifted up and hovered, thereby improving the subsequent heating efficiency.

[0042] Reference Figure 1 , Figure 3 and Figure 5 , wherein the top of the cooling box 4 is respectively fixedly connected with a third conduit 8 and a fourth conduit 81, the ends of the third conduit 8 and the fourth conduit 81 away from the cooling box 4 are both connected to the inner cavity of the heating box 3, and the third conduit 8 and the fourth conduit 81 are both provided with a one-way valve, the output ports of the third conduit 8 and the fourth conduit 81 are symmetrically arranged on both sides of the inner cavity of the heating box 3, and the length of the third conduit 8 is greater than that of the fourth conduit 81, and the one-way valves in the third conduit 8 and the fourth conduit 81 can only allow the high-temperature and high-pressure airflow in the cooling box 4 to enter the heating box 3;

[0043] By setting the above structure, when the high-temperature aluminum alloy material enters the quenching water, part of the quenching water will absorb heat and be vaporized, thereby generating a high-temperature and high-pressure vaporized airflow in the cooling box 4, and the high pressure at this time will open the one-way valves in the third conduit 8 and the fourth conduit 81, and enter the heating box 3 through the third conduit 8 and the fourth conduit 81, firstly making the airflow in the fourth conduit 81 enter the cooling box 4, and blow to the side of the suspended aluminum alloy material from the top of the heating box 3, so that the aluminum alloy material is tilted, and the airflow in the other longer third conduit 8 will be ejected one step later, so as to apply a downward force to the other side of the aluminum alloy material, so as to avoid the aluminum alloy material being tilted too much and causing the suspension failure, so that the aluminum alloy material is in a parallel reciprocating swing, so that the aluminum alloy material is better in contact with the heat in the heating box 3, and the high-temperature airflow can also play a role of auxiliary heating for the aluminum alloy material, thereby improving the heating effect, and the pressure in the heating box 3 is further increased at this time, which will further improve the sealing effect of the sealing plate 52.

[0044] Reference Figure 1-Figure 6 In the present invention, when in use, the aluminum alloy material is placed on the transmission belt 2 and covered just above the guide hole 62. Thereafter, the aluminum alloy material will follow the transmission belt 2 into the heating box 3. When all the aluminum alloy materials enter the heating box 3, the electromagnets 54 on both sides of the heating box 3 are energized. Under the suction of the electromagnets 54, the sealing plate 52 will move down to seal the heating box 3. After the sealing is completed, the heating wire in the heating box 3 is energized to generate heat, so that the temperature in the heating box 3 rises to a threshold range. Then, when the guide hole 62 and the air blowing pipe 63 are just aligned, the conveying frame 1 stops running. At this time, the air pump 64 is turned on to extract the air flow in the heating box 3 through its input end, and fill it into the air flow box 61 from its output end along the air outlet pipes 65 on both sides, so as to generate an upward columnar airflow at the guide hole 62, so as to lift and suspend the aluminum alloy material, so that the aluminum alloy material can be fully heated, and the hot air flow is blown to the aluminum alloy material in a direction, so that the heat is more concentrated.

[0045] After the aluminum alloy material is heated, the sealing plate 52 on the side wall of the heating box 3 is opened, so that the aluminum alloy material follows the transmission belt 2 into the cooling box 4. At the same time, the electromagnet 54 of the cooling box 4 is energized to seal the cooling box 4. The aluminum alloy material will first fall into the cooling box 4, and then the conveying frame 1 continues to operate. The second magnetic plate 74 and the first magnetic plate 72 arranged on the side wall of the driving shaft repel each other, so that the first magnetic plate 72 retracts into the arc plate 71, and then the driving shaft continues to rotate. When the second magnetic plate 74 is separated from the first magnetic plate 72, the inner cavity of the arc plate 71 is connected with the pressure flow groove 77. At this time, the first magnetic plate 72 is reset under the rebound action of the second spring 73, so that the airflow in the inner cavity of the arc plate 71 is pressed into the pressure flow groove 77, and thereby the one-way valve in the pressure flow groove 77 is opened, so that the airflow It moves along the inner cavity of the driving shaft to the first conduits 75 on both sides, and finally fills into the quenching water along the push flow holes 761 on the side walls of the push flow plate 76, thereby forming a thrust in the opposite direction, so that the quenching water on both sides moves toward the side walls of the aluminum alloy material, so that the quenching water in the cooling box 4 is evenly in contact with the aluminum alloy material, thereby effectively improving the cooling efficiency of the aluminum alloy material; when the second magnetic plate 74 contacts and repels the first magnetic plate 72, the heating box 3 is just in the state of turning on the air pump 64 for hovering, and at this time the first magnetic plate 72 retracts into the arc plate 71, which will open the one-way valve in the first conduit 75, so that the airflow in the arc plate 71 enters the airflow box 61 along the second conduit 78, thereby effectively increasing the airflow impulse formed in the guide hole 62 at the initial stage of hovering, so that the aluminum alloy material is quickly lifted up and hovered;

[0046] And when the high-temperature aluminum alloy material enters the quenching water, part of the quenching water will absorb heat and be vaporized, thereby generating a high-temperature and high-pressure vaporized airflow in the cooling box 4, and the high pressure at this time will open the one-way valves in the third duct 8 and the fourth duct 81, and enter the heating box 3 through the third duct 8 and the fourth duct 81. First, the airflow in the fourth duct 81 enters the cooling box 4 and blows to the side of the hovering aluminum alloy material from the top of the heating box 3, so that the aluminum alloy material tilts, and the airflow in the other longer third duct 8 will be ejected one step later, so as to apply a downward force to the other side of the aluminum alloy material, so as to avoid the aluminum alloy material being tilted too much and causing the hovering failure, so that the aluminum alloy material is in a parallel reciprocating swing, so that the aluminum alloy material can better contact with the heat in the heating box 3. Embodiment 2:

[0047] Basically the same as Example 1, on the basis of Example 1, a heat treatment method for aluminum alloy based on metal materials is proposed;

[0048] Reference Figure 1-Figure 6 , a method for heat treatment of aluminum alloy based on metal materials, the steps are as follows:

[0049] S1, sealing the heating box 3 and performing suspension heating on the aluminum alloy;

[0050] The aluminum alloy material is placed on the transmission belt 2 and covered above the guide hole 62. Thereafter, the aluminum alloy material will follow the transmission belt 2 into the heating box 3. When all the aluminum alloy material enters the heating box 3, the electromagnets 54 on both sides of the heating box 3 are energized. Under the suction of the electromagnets 54, the sealing plate 52 is moved down to seal the heating box 3. After the sealing is completed, the heating wire in the heating box 3 is energized to generate heat, so that the temperature in the heating box 3 rises to a threshold value range. Subsequently, when the guide hole 62 is aligned with the air blow pipe 63, the conveying frame 1 stops running. At this time, the air pump 64 is turned on to extract air through its input end. The airflow in the heating box 3 is taken and filled into the airflow box 61 from its output end along the air outlet pipes 65 on both sides, so as to generate an upward columnar airflow at the guide hole 62, so as to lift and suspend the aluminum alloy material, so that the aluminum alloy material can be fully heated, thereby improving the heating effect, and the hot airflow is blown to the aluminum alloy material in a direction, so that the heat is more concentrated, thereby improving the heating efficiency, and after the airflow in the heating box 3 is heated and expanded, the internal air pressure will increase, and at this time, the high pressure will enter the sealing groove 51 along the pressure guide pipe 9, so that the sealing plate 52 is more closely attached to the transmission belt 2, thereby improving the sealing effect during heating;

[0051] S2, sealing the cooling box 4 and quenching and cooling the heated aluminum alloy;

[0052] After the aluminum alloy material is heated, the sealing plate 52 on the side wall of the heating box 3 is opened, so that the aluminum alloy material follows the transmission belt 2 into the cooling box 4. At the same time, the electromagnet 54 of the cooling box 4 is energized to seal the cooling box 4. The aluminum alloy material first falls into the cooling box 4, and then the conveying frame 1 continues to operate. The second magnetic plate 74 and the first magnetic plate 72 arranged on the side wall of the driving shaft repel each other, so that the first magnetic plate 72 retracts into the arc plate 71. Then the driving shaft continues to rotate. When the second magnetic plate 74 is separated from the first magnetic plate 72, the inner cavity of the arc plate 71 coincides with the inner cavity of the arc plate 71. The pressure flow groove 77 is connected, and the first magnetic plate 72 is reset under the rebound effect of the second spring 73, so that the airflow in the inner cavity of the arc plate 71 is pressed into the pressure flow groove 77, and the one-way valve in the pressure flow groove 77 is opened, so that the airflow moves along the inner cavity of the drive shaft to the first conduits 75 on both sides, and finally fills into the quenching water along the push flow holes 761 on the side walls of the push flow plate 76, thereby forming an opposing thrust effect, so that the quenching water on both sides moves toward the side walls of the aluminum alloy material, so that the quenching water in the cooling box 4 is evenly in contact with the aluminum alloy material, thereby effectively improving the cooling efficiency of the aluminum alloy material;

[0053] S3, using the residual impulse generated when the conveying frame 1 is in operation to improve the hovering effect of the rear aluminum alloy;

[0054] When the second magnetic plate 74 contacts and repels the first magnetic plate 72, the heating box 3 is just in the process of starting the air pump 64 for hovering. At this time, the first magnetic plate 72 retracts into the arc plate 71, and the one-way valve in the first conduit 75 is opened, so that the airflow in the arc plate 71 enters the airflow box 61 along the second conduit 78, thereby effectively increasing the airflow impulse formed in the guide hole 62 at the initial stage of hovering, so that the aluminum alloy material is quickly lifted up and hovered, thereby improving the subsequent heating efficiency;

[0055] S4, using the high-temperature and high-pressure airflow emitted by quenching to assist heating and flipping the aluminum alloy heated by hovering at the rear;

[0056] When the high-temperature aluminum alloy material enters the quenching water, part of the quenching water will absorb heat and be vaporized, thereby generating a high-temperature and high-pressure vaporized airflow in the cooling box 4. The high pressure at this time will open the one-way valves in the third conduit 8 and the fourth conduit 81, and enter the heating box 3 through the third conduit 8 and the fourth conduit 81 at the same time. First, the airflow in the fourth conduit 81 enters the cooling box 4 and blows to the side of the suspended aluminum alloy material from the top of the heating box 3, so that the aluminum alloy material is tilted. The airflow in the other longer third conduit 8 will be ejected one step later, so as to apply a downward force to the other side of the aluminum alloy material to avoid the aluminum alloy material being tilted too much and causing a hovering failure, so that the aluminum alloy material is in a parallel reciprocating swing, so that the aluminum alloy material is better in contact with the heat in the heating box 3, and the high-temperature airflow can also play a role in auxiliary heating for the aluminum alloy material, thereby improving the heating effect. At this time, the pressure in the heating box 3 is further increased, which will further improve the sealing effect of the sealing plate 52.
