A driving motor 3 is installed on the side of the base plate 1, one end of the screw rod 2 is installed on the output shaft of the driving motor 3, and a threaded block 4 is threadedly sleeved on the screw rod 2. The movable plate 5 is installed on the top of the threaded block 4, and the lifting mechanism includes a first electric liquid pushing rod 12 installed on the top of the heat treatment box 8, and a lifting plate 13 is installed on the output end of the first electric liquid pushing rod 12. Two moving rods 14 are installed at the bottom of the lifting plate 13, and two through holes are opened at the top of the heat treatment box 8. The two moving rods 14 pass through the two through holes respectively, and two isolation plates 15 are respectively installed at the bottom of the two moving rods 14.

[0023] With the above structure, when in use, first place two aluminum alloys to be processed on the placement plate 7, and then start the telescopic hydraulic cylinder 6. The start of the telescopic hydraulic cylinder 6 will cause the placement plate 7 to rise, and the rise of the placement plate 7 will cause the two aluminum alloys to be processed to rise, so that the two aluminum alloys to be processed are respectively placed in the processing chamber 9 and one of the preheating chambers 10, and then start the heating block 11 to heat treat one of the aluminum alloys to be processed. When one of the aluminum alloys is processed, first start the first electric hydraulic rod 12. The output of the first electric hydraulic rod 12 will cause the lifting plate 13 to rise. The rise of the lifting plate 13 will cause the moving rod 14 to rise. The rise of the moving rod 14 will cause the isolation plate 15 to rise.

The drive motor 3 will cause the screw rod 2 to rotate, and the rotation of the screw rod 2 will cause the threaded block 4 to move. The movement of the threaded block 4 will cause the moving plate 5, and the movement of the moving plate 5 will pass through the telescopic hydraulic cylinder 6. The retracting hydraulic cylinder 6 moves the placement plate 7, and at the same time, the output of the second electric hydraulic push rod 22 will move the moving block 23, and the movement of the moving block 23 will move the blocking plate 24, thereby blocking and unblocking the two preheating chambers 10. At this time, the first electric hydraulic push rod 12 and the isolation plate 15 are used to isolate the processing chamber 9 and the preheating chamber 10, and then the telescopic hydraulic cylinder 6 is used to lower one of the placement plates 7 to a certain position. When it is lowered, one of the second electric hydraulic push rods 22 is started again, so that the blocking plate 24 blocks the preheating chamber 10, and then the placement plate 7 is lowered by the telescopic hydraulic cylinder 6, and then the processed aluminum alloy is replaced. When replaced, the placement plate 7 is raised again, and then the blocking plate 24 is unblocked, and this is repeated in sequence, so that the aluminum alloy can be loaded and unloaded in a small space to avoid the opening being too large to cause a large amount of heat to escape. At the same time, most of the heat escaped from the processing chamber 9 enters the preheating chamber 10 to preheat the aluminum alloy for easy use.

[0024] like Figure 1 , Figure 2 and Figure 4As shown, the opposite inner walls of the two preheating chambers 10 are rotatably mounted with rotating rods, the side of the heat treatment box 8 is mounted with a servo motor 17, one end of one rotating rod is mounted on the output shaft of the servo motor 17, the two rotating rods are sleeved with movable blocks 16, the bottoms of the two movable blocks 16 are mounted with multiple nozzles, the side of the heat treatment box 8 is mounted with a circulating fan 20, the output end of the circulating fan 20 is mounted with a three-way pipe 21, two solenoid valves are arranged on the three-way pipe 21, the other two ends of the three-way pipe 21 are connected with the multiple nozzles through a shunt pipe, and the two The two rotating rods are installed in cooperation with each other through a transmission mechanism, and the transmission mechanism includes a transmission wheel 18 respectively installed at one end of the two rotating rods, and a belt 19 is tensioned on the two transmission wheels 18. The advantage of such an arrangement is that through the arrangement of the nozzle, the circulating fan 20, the three-way pipe 21 and the solenoid valve, it is convenient to transmit hot air in the preheating chamber 10, thereby preheating the aluminum alloy. Through the arrangement of the rotating rod, the movable block 16, the servo motor 17, the transmission wheel 18 and the belt 19, the angle of the nozzle can be changed, thereby uniformly preheating the aluminum alloy.

[0025] like Figure 1 As shown, a PLC controller is installed on the side of the heat treatment box 8. The advantage of this arrangement is that through the setting of the PLC controller, it is convenient to control the drive motor 3, the telescopic hydraulic cylinder 6, the first electric hydraulic rod 12, the servo motor 17 and the second electric hydraulic rod 22.

[0026] How this utility works:

[0027] When in use, firstly, two aluminum alloys to be processed are placed on the placement plate 7, and then the telescopic hydraulic cylinder 6 is started through the PLC controller. The start of the telescopic hydraulic cylinder 6 will cause the placement plate 7 to rise, and the rise of the placement plate 7 will cause the two aluminum alloys to be processed to rise, so that the two aluminum alloys to be processed are respectively placed in the processing chamber 9 and one of the preheating chambers 10, and then the heating block 11, the servo motor 17 and the circulating fan 20 are started. The heating of the heating block 11 will heat treat one of the aluminum alloys to be processed, and the output of the circulating fan 20 will pass through the three-way pipe 21, the nozzle and the solenoid valve to blow the hot air in the processing chamber 9. Output to one of the preheating chambers 10, at this time the output of the servo motor 17 will drive one of the rotating rods to rotate, the rotation of one of the rotating rods will cause the movable block 16 to swing through the transmission wheel 18 and the belt 19, the swing of the movable block 16 will cause the jet head to adjust a certain angle, and then preheat the other aluminum alloy evenly. When one of the aluminum alloys is processed, the first electric liquid push rod 12 is started first, the output of the first electric liquid push rod 12 will cause the lifting plate 13 to rise, the lifting plate 13 will rise, the moving rod 14 will rise, the moving rod 14 will rise, and the isolation plate 15 will rise. At this time, a small part of the hot air will escape to In the preheating chamber 10, the driving motor 3 and the two second electric hydraulic rods 22 are turned on, the driving motor 3 will cause the screw rod 2 to rotate, the screw rod 2 will cause the threaded block 4 to move, the threaded block 4 will cause the moving plate 5 to move, the moving plate 5 will cause the placement plate 7 to move through the telescopic hydraulic cylinder 6, and at the same time, the output of the second electric hydraulic rod 22 will cause the moving block 23 to move, the moving block 23 will cause the blocking plate 24 to move, and then the two preheating chambers 10 will be blocked and unblocked. At this time, the first electric hydraulic rod 12 and the isolation plate 15 will isolate the processing chamber 9 and the preheating chamber 10, and then the telescopic hydraulic cylinder will be used to isolate the processing chamber 9 and the preheating chamber 10. 6 makes one of the placement plates 7 drop to a certain position. When it is dropped, one of the second electric push rods 22 is started to make the blocking plate 24 block the preheating chamber 10. Then the placement plate 7 is dropped by the telescopic hydraulic cylinder 6 to replace the processed aluminum alloy. When it is replaced, the placement plate 7 is raised again, and then the blocking plate 24 is unblocked. This process is repeated in sequence, so that the aluminum alloy can be loaded and unloaded in a small space to avoid a large amount of heat escaping due to an opening that is too large. At the same time, most of the heat escaping from the processing chamber 9 enters the preheating chamber 10 to preheat the aluminum alloy for easy use.
