Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy processing technology, and in particular to an aluminum alloy temperature field control heating device. Background Technology

[0002] Aluminum alloys require heating in a furnace during processing. The temperature field of an aluminum alloy refers to the temperature distribution in space and time on its interior and surface during heating, as well as the dynamic evolution of this distribution with changes in time and spatial coordinates. It is the core physical field describing the thermal state of aluminum alloys, reflecting the combined effects of heat conduction, convection, radiation, and latent heat release during phase transformation within the material. The distribution and evolution of the temperature field directly affect the microstructure, performance, and processing defects of aluminum alloys, making it an important research object in aluminum alloy processing and applications. For example, in the forging or rolling process of aluminum alloys, an uneven temperature field can lead to local grain coarsening or uneven hardening, causing defects such as cracking and warping. During the heat treatment stage, temperature fluctuations exceeding ±5℃ can significantly affect the precipitation kinetics of strengthening phases, resulting in excessive performance dispersion.

[0003] A Chinese patent (publication number: CN220959516U) discloses an aluminum alloy heating rod furnace, relating to the field of aluminum alloy processing technology. It includes a base and a furnace body mounted on top of the base for heating the aluminum alloy. A support platform is rotatably mounted on the top surface of the base. This device enables the aluminum alloy to be in a state of dynamic heating, avoiding localized heating and uneven temperature rise, thus improving the heating efficiency of the aluminum alloy. During heat treatment (solution treatment, aging), temperature fluctuations exceeding ±5℃ significantly affect the precipitation kinetics of strengthening phases, leading to excessive performance dispersion. Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Although the device can move the aluminum alloy by rotating the placement cylinder during use, if the aluminum alloy is small in volume, a lot of aluminum alloy will be placed in the placement cylinder at one time, and the aluminum alloy will pile up together. It is difficult for the rotation of the placement cylinder to quickly flip the inner aluminum alloy to the outer side. The inner aluminum alloy needs a long time to move to the outer side, thus affecting the heating efficiency of the aluminum alloy. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0018] Reference Figure 1-6 As shown, this utility model provides a technical solution: an aluminum alloy temperature field control heating device, including a base 1; a heating furnace 2 is fixedly connected to the top surface of the base 1; a baffle 3 is provided on the top of the base 1; a placement cylinder 4 is provided on the side wall of the baffle 3; a rotating assembly 5 is installed on the baffle 3; the rotating assembly 5 is fixedly connected to one end of the placement cylinder 4; four exhaust pipes 6 are provided in the inner cavity of the placement cylinder 4; several exhaust ports 7 are opened on the exhaust pipes 6; one end of the exhaust pipe 6 is fixedly sleeved on one end of the placement cylinder 4 and extends to the outside; one end of the four exhaust pipes 6 together... An air inlet plate 8 is fixedly connected to the heating furnace 2, and a rotary joint 9 is installed on the air inlet plate 8. An air pump 10 is fixedly connected to the outer wall of one side of the heating furnace 2. An air outlet pipe 11 is fixedly connected to the air outlet end of the air pump 10. The air outlet pipe 11 is matched with the rotary joint 9. One end of the air outlet pipe 11 is fixedly sleeved on the side wall of the heating furnace 2 and passes through the inner cavity. A three-way connector 12 is fixedly connected to the air inlet end of the air pump 10. A first air extraction pipe 13 is installed at the interface of one end of the three-way connector 12. One end of the first air extraction pipe 13 is fixedly connected to one side of the heating furnace 2 and passes through the inner cavity.

[0019] In order to heat the interior of the heating furnace 2 and simultaneously monitor the temperature inside the heating furnace 2, a heater 14 is fixedly connected to the inner wall of the heating furnace 2, and a temperature sensor 15 is fixedly connected to the outer wall of the heating furnace 2. The sensing end of the temperature sensor 15 extends through the inner cavity of the heating furnace 2.

[0020] To stop the extraction of hot air from the heating furnace 2 and to allow the extraction of cold air from the outside, a second extraction pipe 16 is installed at one end of the three-way connector 12. The first extraction pipe 13 and the second extraction pipe 16 are connected to the two ports of the three-way connector 12 respectively via solenoid valves 17. When extracting hot air from the heating furnace 2, the solenoid valve 17 on the first extraction pipe 13 is open, while the solenoid valve 17 on the second extraction pipe 16 is closed. Conversely, when extracting outside air, the solenoid valve 17 on the second extraction pipe 16 is open, while the solenoid valve 17 on the first extraction pipe 13 is closed.

[0021] In order to enable the placement cylinder 4 to rotate, the rotating assembly 5 includes a motor 51, which is fixedly connected to the baffle 3 via a frame. The motor 51 has a connecting shaft 52 fixedly connected to its shaft. The connecting shaft 52 passes through the baffle 3 and is rotatably connected. One end face of the connecting shaft 52 is fixedly connected to one end face of the outer wall of the placement cylinder 4.

[0022] To support both ends of the placement cylinder 4 and reduce the downward pressure applied to the connecting shaft 52, a support plate 18 is fixedly connected to one side of the baffle 3. Support rings 19 are fixedly connected to both sides of the top of the support plate 18, and both ends of the placement cylinder 4 are respectively movably sleeved in the two support rings 19.

[0023] To allow heat from the heating furnace 2 to enter the placement cylinder 4, several through holes are provided on the surface of the placement cylinder 4. A material discharge opening is provided on the side wall of the placement cylinder 4. A cylinder cover 20 is rotatably attached to the side wall of the placement cylinder 4 via a pin. The cylinder cover 20 is inserted into the placement opening, and one side of the cylinder cover 20 is bolted to the placement cylinder 4. The cylinder cover 20 can be fixed or released by turning the bolt.

[0024] In order to move the baffle 3, electric push rods 21 are fixedly connected to both sides of the top surface of the outer wall of the heating furnace 2. The telescopic ends of the two electric push rods 21 are fixedly connected to the side wall of the baffle 3 near the top. When heating the aluminum alloy, the baffle 3 covers the opening of the heating furnace 2 to prevent heat from being lost from the opening.

[0025] In order to support the lower side of the baffle 3 while reducing the frictional resistance on the lower side of the baffle 3, slide rails 22 are fixedly connected to both sides of the top surface of the base 1, and the bottom of the baffle 3 is slidably connected to the two slide rails 22.

[0026] Working Principle: During operation, first open the cylinder cover 20, and place the aluminum alloy into the placement cylinder 4 through the discharge opening. Then, close the cylinder cover 20 and secure it firmly with bolts. Next, start the electric actuator 21 to pull the baffle 3, thereby smoothly feeding the placement cylinder 4 into the heating furnace 2. At this time, the baffle 3 is exactly at the opening position of the heating furnace 2, effectively preventing heat loss from the opening. Then, turn on the heater 14 to heat the aluminum alloy in the placement cylinder 4. At the same time, start the motor 51 to drive the connecting shaft 52 to rotate. The connecting shaft 52 drives the placement cylinder 4 to rotate together, so that the aluminum alloy in the placement cylinder 4 rotates and is heated, ensuring uniform heating. After the placement cylinder 4 enters the heating furnace 2, one end of the air outlet pipe 11 will automatically insert into the rotary joint 9. When the heater 14 is running, the temperature inside the heating furnace 2 gradually rises, and the air pump 10 starts to work, extracting the hot air from the heating furnace 2 and discharging it into the air inlet plate 8 through the air outlet pipe 11. The intake plate 8 then distributes the hot air into the four exhaust pipes 6, and the hot air is discharged through the exhaust ports 7 on the exhaust pipes 6, preheating the inner aluminum alloy. This significantly reduces the time required for the inner aluminum alloy to reach the designated temperature when it moves to the outer side, effectively improving the heating efficiency of the device. Furthermore, the temperature sensor 15 equipped with the device can monitor the temperature inside the heating furnace 2 in real time. If the temperature is too high, the solenoid valve 17 on the first extraction pipe 13 can be closed, while the solenoid valve 17 on the second extraction pipe 16 can be opened. At this time, the extraction pump 10 draws in cooler outside air through the second extraction pipe 16 and discharges it into the interior of the heating furnace 2 and the aluminum alloy, thereby reducing the temperature inside the heating furnace 2 and the aluminum alloy. This achieves precise control of the temperature inside the heating furnace 2 and the temperature field of the aluminum alloy, preventing excessively high temperatures from affecting the microstructure and performance of the aluminum alloy.

[0027] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
