[0021] Furthermore, the heat treatment support frame 12 is in the shape of a "cylinder", the outer wall of the heat treatment support frame 12 is grid-shaped, when the heat treatment support frame 12 moves into the furnace cavity 2, when the heat treatment support frame 12 contains aluminum alloy workpieces, the heat in the furnace cavity 2 can heat-treat the aluminum alloy workpieces through the grid.

[0022] Please refer to Figures 1-4 , the slide rail component includes an electric slide rail 4 and a track body 3, the electric slide rail 4 is fixedly connected to the bottom of the moving bottom plate 5, the track body 3 is arranged on the inner bottom wall of the furnace cavity 2, the electric slide rail 4 is slidably connected to the track body 3, the electric slide rail 4 is an existing device and will not be explained in detail here, and the electric slide rail 4 can drive the moving bottom plate 5 to move inside the furnace cavity 2 through an external system control.

[0023] Please refer to Figures 1-6, the feeding and discharging component includes a feeding channel 121. The feeding channel 121 is opened on the outer wall of the heat treatment support frame 12. A telescopic groove 122 is opened on the inner wall of the feeding channel 121. A frame door 123 is slidably connected to the inner wall of the telescopic groove 122. A driving component is arranged on the outer wall of the rotating column 10. When the frame door 123 retracts into the telescopic groove 122, the aluminum alloy workpiece can be put into the heat treatment support frame 12 through the feeding channel 121.

[0024] Furthermore, the feeding channel 121 is of an arc structure, and the shape of the frame door 123 is the same as that of the feeding channel 121. The frame door 123 can limit the position of the feeding channel 121, so that the aluminum alloy workpiece will not be discharged through the feeding channel 121 during the heat treatment process.

[0025] Please refer to Figures 1-6 , the driving component includes a heat-resistant machine box 13 and a toothed plate 124. A motor is fixedly installed on the inner wall of the heat-resistant machine box 13, and the output end of the motor is fixedly connected to a driving rod 14 through a coupling.

[0026] Furthermore, the toothed plate 124 is of an arc structure. The toothed plate 124 and the third gear 15 are both made of high-temperature resistant steel plates, and the toothed plate 124 can move into the telescopic groove 122.

[0027] Using the production process of the aluminum alloy workpiece aging heat treatment production line described in any one of 8, including the following steps: S1: The electric slide rail 4 drives the movement of the moving bottom plate 5, so that the first furnace door 7 moves to the outside of the furnace chamber 2. The motor inside the heat-resistant machine box 13 drives the driving rod 14 to rotate. The driving rod 14 drives the toothed plate 124 to rotate through the third gear 15, aligns the discharge hopper with the feeding channel 121, and loads the aluminum alloy workpiece into the heat treatment support frame 13. S2: The motor can drive the frame door 123 to reset by the same principle. The electric slide rail 4 can drive the heat treatment support frame 12 with the aluminum alloy workpiece to move into the heat treatment combustion furnace 1 through the moving bottom plate 5. S3: The heat treatment combustion furnace 1 performs heat treatment on the aluminum alloy workpieces. The motor 11 drives the first gear 112 to rotate, and drives the heat treatment support frame 12 to rotate through the second gear 113. The rotation of the heat treatment support frame 12 can change the position of the aluminum alloy workpieces, thereby avoiding the situation that one side where the aluminum alloy workpieces are stacked together is always covered. S4: The heat treatment support frame 12 moves the frame door 123 into the inside of the telescopic groove 122 by the same principle. Then, the next batch of aluminum alloy workpieces to be heat-treated can be loaded into the inside of the heat treatment support frame 12, and the heat-treated aluminum alloy workpieces are moved out of the furnace cavity 2. S5: Rotate the heat treatment support frame 12 so that the feed channel 121 is located below. The collecting hopper for collecting the heat-treated workpieces is inside the collecting groove 6. Then, when the frame door 123 moves inside the net telescopic groove 122, the aluminum alloy workpieces will be discharged into the inside of the collecting hopper. The heat treatment support frame 12 containing the untreated aluminum alloy workpieces on the other side of the second furnace door 8 moves into the inside of the furnace cavity 2. The second furnace door 8 and the third furnace door 9 close both sides of the furnace cavity 2.

[0028] Please refer to Figures 1-6 , the control component includes the motor 11 and the second gear 113. The output end of the motor 11 is fixedly connected with a first rotating rod 111 through a coupling. One end of the first rotating rod 111 is fixedly connected with a first gear 112. One end of the rotating column 10 is rotatably sleeved with the first furnace door 7. One side of the second gear 113 is fixedly connected with one end of the rotating column 10. The first gear 112 is meshed with the second gear 113. The motor 11 drives the first gear 112 to rotate, and then drives the heat treatment support frame 12 to rotate through the second gear 113. Then, during the heat treatment process, the rotation of the heat treatment support frame 12 can change the position of the aluminum alloy workpieces, thereby avoiding the situation that one side where the aluminum alloy workpieces are stacked together is always covered, resulting in uneven heating.

[0029] Working principle: The electric slide rail 4 drives the movement of the moving bottom plate 5, causing the first furnace door 7 to move outside the furnace cavity 2. The heat treatment support frame 12 is located outside the furnace cavity 2. The motor inside the heat-resistant chassis 13 drives the drive rod 14 to rotate. The drive rod 14 drives the toothed plate 124 to rotate through the third gear 15, and then can drive the frame door 123 to move into the inside of the telescopic groove 122. Then, a device with relatively small aluminum alloy workpieces can align the discharge hopper with the feed channel 121 and load the aluminum alloy workpieces into the inside of the heat treatment support frame 12. The motor can drive the frame door 123 to reset by the same principle. Subsequently, the electric slide rail 4 can drive the heat treatment support frame 12 with the aluminum alloy workpieces through the moving bottom plate 5 into the inside of the heat treatment combustion furnace 1. The heat treatment combustion furnace 1 performs heat treatment on the aluminum alloy workpieces. During the heat treatment process, the motor 11 is started. The motor 11 drives the first gear 112 to rotate, and then drives the heat treatment support frame 12 to rotate through the second gear 113. Then, during the heat treatment process, the rotation of the heat treatment support frame 12 can change the position of the aluminum alloy workpieces, thereby avoiding the situation that the side where the aluminum alloy workpieces are stacked together is always covered, resulting in uneven heating. The heat treatment support frame 12 located on the other side of the second furnace door 8 makes the frame door 123 move into the inside of the telescopic groove 122 by the same principle. Then, the next batch of aluminum alloy workpieces to be heat-treated can be loaded into the inside of the heat treatment support frame 12. The electric slide rail 4 drives the movement of the moving bottom plate 5, causing the heat-treated aluminum alloy workpieces to move out of the furnace cavity 2. At this time, the heat treatment support frame 12 is rotated so that the feed channel 121 is located below. The collection hopper for collecting the heat-treated workpieces is located inside the collection groove 6. Then, when the frame door 123 moves inside the net telescopic groove 122, the aluminum alloy workpieces will be discharged into the inside of the collection hopper. During the discharging process of the heat-treated aluminum alloy workpieces, the heat treatment support frame 12 with the untreated aluminum alloy workpieces located on the other side of the second furnace door 8 moves into the inside of the furnace cavity 2. The second furnace door 8 and the third furnace door 9 close both sides of the furnace cavity 2, so that the next batch of aluminum alloy workpieces can be heat-treated in a timely manner without waiting for the heat-treated aluminum alloy workpieces to be discharged and collected.
