Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy ingot processing equipment, and in particular to a device for preheating and equalizing aluminum alloy ingots. Background Technology

[0002] Before processing aluminum alloy ingots (such as die casting, forging, etc.), the temperature of the aluminum alloy ingots needs to be raised to a suitable range, and the temperature of each part of the aluminum alloy ingot should be as uniform as possible. This can effectively control the initial temperature of the aluminum alloy ingot, provide good temperature conditions for subsequent processing, and thus improve the processing performance of aluminum alloy materials, such as reducing its deformation resistance and improving its fluidity.

[0003] However, existing aluminum alloy ingot preheating and temperature equalization equipment is prone to uneven heating of aluminum alloy ingots during operation. The reason for this is that after the workers pour the aluminum alloy ingots into the equipment, the ingots accumulate in the equipment, and during preheating, it is not possible to heat each aluminum alloy ingot evenly.

The stirring paddle 11 can be driven to rotate by the turbulence servo motor 10, thereby stirring the steam in the heat preservation chamber 12.

[0025] In this embodiment, the placement mechanism includes a linkage slider 15, a drive column 16, a crank assembly, and two vibration springs 21. The top of the placement base 14 is provided with a sliding groove, and the linkage slider 15 is slidably installed on the inner wall of the bottom of the sliding groove. Vibration springs 21 are fixedly installed on both sides of the linkage slider 15. The other ends of the two vibration springs 21 are respectively connected to the inner wall of one side of the corresponding sliding groove.

[0027] In this embodiment, a motor slot is provided inside the storage base 14, and a storage servo motor 20 is fixedly installed on one inner wall of the motor slot. The output shaft of the storage servo motor 20 is fixedly connected to the long crank 19, so that the long crank 19 can be rotated by the storage servo motor 20.

[0028] The exhaust fan and boiler mentioned in this embodiment are all auxiliary equipment for the preheating equipment, which are common knowledge in the field, so they are not explained in detail or described with accompanying drawings.

[0029] Working principle: During the preheating of aluminum alloy ingots, the operator pours the ingots into the insulation chamber 12 through the inlet. The ingots fall onto the steel mesh plate 13. Then, the placement servo motor 20 is activated via the control panel. The servo motor 20 drives the long crank 19 to rotate, which in turn moves the connecting column 18. The connecting column 18 then moves the short crank 17. Since the short crank 17 is mounted on the drive column 16, which is fixedly installed on one side of the linkage slider 15, the short crank 17 drives the linkage slider 15 to move back and forth. The linkage slider 15 is affected by two vibration springs 21 during this movement, resulting in only small-amplitude but high-frequency vibrations. The vibration of the linkage slider 15 causes the steel mesh plate 13 to vibrate, thus... The aluminum alloy ingots on the surface are more evenly distributed. After the staff closes the sealing door 2, they start the boiler to generate steam. The steam enters the steam box 3 through two steam pipes 4. The steam in the left steam pipe 4 enters the heat preservation chamber 12 to preheat the aluminum alloy ingots. The steam in the other steam pipe 4 enters the heat preservation chamber 12 through multiple sinking pipes 5. At this time, this part of the steam is located in the bottom area of ​​the heat preservation chamber 12. One end of the exhaust pipe 8 is connected to the exhaust fan and moves upward under the suction of the exhaust pipe 8. This part of the steam heats the bottom of the aluminum alloy ingots. At the same time, the turbulence servo motor 10 starts and drives the stirring paddle 11 to rotate, stirring the steam in the heat preservation chamber 12, making the steam distribution more even, and thus making the heating of the aluminum alloy ingots more even.

[0030] The technological advancements of this invention compared to existing technologies are as follows: after the aluminum alloy ingots are poured into the equipment, vibration is used to make the ingots more evenly distributed, reducing the occurrence of accumulation. Furthermore, the set turbulence mechanism can agitate the hot air inside the equipment, making the hot air distribution inside the equipment more uniform, which can effectively heat the aluminum alloy ingots and increase the preheating effect of the equipment.
