Two groups of cylinders 2 are symmetrically arranged on both sides of the outer wall of the quenching box 1, and the output shaft end of the cylinder 2 and both sides of the baffle 3 are fixedly connected.

[0039] In this embodiment, a quenching box 1 is provided, and electric heating wires 5 are installed on the inner wall of the quenching box 1, including the inner top wall, the side walls on both sides and the inner bottom surface. When the aluminum alloy supporting device storage frame 6 enters the quenching box 1, the electric heating wires 5 are started to heat the aluminum alloy to a temperature above the solvus line and keep it warm for a period of time.

[0040] Specifically, two groups of cylinders 2 are started to drive the baffle 3 to move upward along two groups of door tracks 4, the quenching box 1 is opened, the electric heating wire 5 is started to start heating, and after the storage frame 6 enters the quenching box 1, the cylinder 2 is controlled again to drive the baffle 3 to move downward, and the quenching box 1 is closed.

[0041] The storage frame 6 is provided with a fixed frame and a rotating frame, and the rotating frame is used to move and flip the aluminum alloy;

[0042] In this embodiment, a fixed frame and a rotating frame are used to support the aluminum alloy parts. During the high-temperature quenching treatment and the cooling treatment, the rotating frame is used to rotate inside the fixed frame to avoid stacking of the aluminum alloy parts. Continuous and repeated shifting and flipping ensure that gaps are always maintained between the aluminum alloy parts.

[0045] The rotating frame includes a second support rod 10 and a second connecting rod 11, the second supporting rod 10 is connected to the second connecting rod 11 on both sides, one end of the second connecting rod 11 is rotatably connected to the swing rod 12, one end of the swing rod 12 is fixedly installed with a rotating shaft 13, one end of the rotating shaft 13 is rotatably connected to one side of the storage frame 6, and one end of the rotating shaft 13 is fixedly installed with a second synchronous pulley 17, the two sets of second synchronous pulleys 17 are connected through the first transmission belt 15, one end of the rotating shaft 13 is fixedly installed with a first synchronous pulley 16, a motor 14 is fixedly installed on one side of the outside of the storage frame 6, the output shaft end of the motor 14 is fixedly installed with the first synchronous pulley 16, and the two sets of first synchronous pulleys 16 are connected through the second transmission belt 18.

[0046] In this embodiment, 12 groups of second support rods 10 are provided, and two groups of second connecting rods 11 are used to fixly connect the second support rods 10 on both sides thereof, and the second support rods 10 are provided within the spacing between two adjacent groups of first support rods 8. The second support rods 10 and the first support rods 8 are arranged in an equidistant array, and rod-shaped supports are provided to reduce the contact surface with the aluminum alloy parts as much as possible, so as to maximize the processing area of ​​the parts for high-temperature quenching and cooling.

[0047] Specifically, the motor 14 is started, and the first synchronous pulley 16 at the output shaft end of the motor 14 drives the first synchronous pulley 16 at the shaft end of the rotating shaft 13, thereby driving the rotating shaft 13 to rotate, and the second synchronous pulley 17 at the end of the rotating shaft 13 drives another group of second synchronous pulleys 17 at the end of the rotating shaft 13 through the first transmission belt 15, thereby realizing the rotation of the two groups of rocker arms 12, and finally driving the second support rod 10 to rotate between the adjacent first support rods 8, and in the process of its rising and falling, the aluminum alloy parts are moved and flipped.

[0048] Specifically, the distance between the second support rod 10 and the first support rod 8 is between 10 mm and 15 mm, which is set according to the specifications and shapes of the parts to prevent the parts from falling during the rotation of the second support rod 10.

[0049] The storage frame 6 is configured as a top-to-bottom through structure, and a through hole 7 is provided in the storage frame 6. A guide rail 21 is provided at the bottom of the storage frame 6, a guide groove 22 is provided in the guide rail 21, and the guide rail 21 extends into the quenching box 1. A bracket 19 is symmetrically provided on the outer wall of the storage frame 6, and a movable roller 20 is rotatably installed at the bottom of the bracket 19, and the movable roller 20 is rotatably installed in the guide groove 22.

[0050] In this embodiment, at least six groups of movable rollers 20 are arranged at the bottom of the storage frame 6, and the movable rollers 20 are connected to the driving motor to realize the automatic movement of the storage frame 6, and drive the storage frame 6 to move into the quenching box 1 or the cooling area according to the needs of high-temperature quenching treatment and cooling.

[0051] The spray assembly and the jet assembly are used for cooling the aluminum alloy. When the storage frame 6 is moved into the cooling area, the spray assembly is arranged above the storage frame 6, and the jet assembly is arranged below the storage frame 6. The spray assembly includes a spray cover 25, and a water tank 26 is installed in the spray cover 25. The water tank 26 is connected to an external water pump, and a spray pipe 27 is connected to the bottom of the water tank 26.

[0052] In this embodiment, the storage frame 6 is removed from the quenching box 1 after the high-temperature quenching treatment is completed, and enters the cooling zone. The external water pump is started to spray the cooling water onto the surface of the aluminum alloy through the spray pipe 27. At this time, the motor 14 still drives the rotating frame to ensure that the aluminum alloy parts and the cooling water are in full contact in time. The cooling effect does not require manual removal of the parts and is completed directly after the high-temperature quenching treatment;

[0053] It should be noted that the spray assembly and the injection assembly are connected to ensure timely cooling after high-temperature quenching treatment, and the parts that do not meet the cooling standards are returned to the quenching box 1 for secondary high-temperature quenching treatment until the heat-treated products meet the standards.

[0054] The injection assembly includes a cooling circulation box 28 , in which a sealing chamber 31 is provided, in which a piston plate 32 is slidably mounted, and a spray pipe 33 is connected to the top of the cooling circulation box 28 .

[0055] The cooling area is located below the storage frame 6 and is provided with a spray pipe 33. The piston plate 32 is used to squeeze the cooling water in the cooling circulation box 28, and the cooling water in the cooling circulation box 28 is sprayed toward the aluminum alloy parts through the bottom. In conjunction with the spray assembly above, the cooling area of ​​the device for the aluminum alloy parts is increased.

[0056] A push rod 24 is fixedly connected to the top of the piston plate 32, and an electromagnet 23 is fixedly installed on one side of the outer wall of the storage frame 6. The electromagnet 23 and the push rod 24 are electrically coordinated. A slide groove 29 is opened at the top of the sealing cavity 31 at the sliding position of the push rod 24, and an accordion plate 30 is arranged in the slide groove 29.

[0057] In this embodiment, an electromagnet 23 is provided on the outer wall of one side of the storage frame 6. The electromagnet 23 and the push rod 24 are electrically attracted to each other. When the storage frame 6 moves toward the cooling area, the piston plate 32 is driven to move in the cooling circulation box 28, which serves as a driving force to trigger the spraying. The sprayed and injected cooling water then flows back into the cooling circulation box 28. During the movement of the storage frame 6, the piston plate 32 can still be reset to squeeze the remaining water in the sealing cavity 31 and spray the bottom of the storage frame 6, thereby enhancing the cooling time and ensuring the cooling effect.

[0058] The cooling circulation box 28 as a whole adopts a cooling plate structure to ensure that the water temperature meets the cooling standard.

[0059] It should be noted that the push rod 24 and the cooling circulation box 28 can both be moved to change positions and cooperate with the storage frame 6 to cool and keep the space warm after cooling.

[0060] In the present invention, two groups of cylinders 2 are started to drive the baffle 3 to move upward along two groups of door tracks 4, the quenching box 1 is opened, the electric heating wire 5 is started, and at the same time, the storage frame 6 is driven into the quenching box 1 by the moving roller 20, the cylinder 2 is started to drive the baffle 3 to move downward, the quenching box 1 is closed, and the aluminum alloy is heated to a temperature above the solvus line and kept warm for a period of time;

[0061] The storage frame 6 is in the quenching box 1, and the motor 14 is started, which drives the two sets of swing rods 12 to rotate through the first synchronous pulley 16, the rotating shaft 13 and the second synchronous pulley 17 in sequence, and finally drives the second support rod 10 to rotate between the adjacent first support rods 8. During the rising and falling process, the aluminum alloy parts are moved and turned over. The continuous and repeated moving and turning ensure that the gap between the aluminum alloy parts is always maintained, and the smaller parts can be turned over, so that the aluminum alloy parts are evenly heated and cooled, and the performance of the aluminum alloy parts after high-temperature quenching and cooling treatment is improved;

[0062] After completion, start the cylinder 2 to open the quenching box 1, and move the roller 20 to drive the storage frame 6 to move out of the quenching box 1 to the cooling area. After entering the cooling area, start the external water pump to spray the cooling water onto the surface of the aluminum alloy through the spray pipe 27. At this time, the motor 14 still drives the rotating frame to ensure that the aluminum alloy parts and the cooling water are in timely and sufficient contact. The cooling effect does not require manual removal of the parts and is completed directly after the high-temperature quenching treatment.

[0063] An electromagnet 23 is provided on the outer wall of one side of the storage frame 6. The electromagnet 23 and the push rod 24 are electrically attracted to each other. When the storage frame 6 moves toward the cooling area, the piston plate 32 is driven to move in the cooling circulation box 28, which serves as a driving force to trigger the spraying. The sprayed and injected cooling water then flows back into the cooling circulation box 28. During the movement of the storage frame 6, the piston plate 32 can still be reset to squeeze the remaining water in the sealing cavity 31 and spray the bottom of the storage frame 6, thereby increasing the cooling time and ensuring the cooling effect.

[0064] The present invention also provides an aluminum alloy heat treatment method, comprising the following steps:

[0065] Step 1: high temperature quenching, placing the aluminum alloy parts in the storage frame 6, using the moving roller 20 to drive the aluminum alloy to move into the quenching box 1, and opening and closing the baffle 3 to facilitate the storage frame 6 to move into the quenching box 1 for high temperature quenching treatment;

[0066] Step 2: Use the moving roller 20 to drive the storage frame 6 to move to the cooling area;

[0067] Step 3: After the storage frame 6 enters the cooling area, the external water pump is started, and the aluminum alloy parts are cooled in time by using the spray pipe 27;

[0068] Step 4: The injection assembly below the storage frame 6 also acts synchronously with step 3. The piston plate 32 follows the movement of the storage frame 6 and pressurizes the sealed cavity 31 to timely cool the aluminum alloy parts through the injection pipe 33.
