Description

Technical Field

[0001] This utility model relates to the field of metal solidification and metallurgical technology, specifically to a device based on the monitoring and coupling of the metal solidification thermal process and real-time liquid quenching. Background Technology

[0002] The quenching of aluminum alloys differs from that of general structural steel. The time between removing the aluminum alloy from the furnace after holding it at room temperature and immersing it in the quenching medium is called the quenching transfer time. If the transfer time is too long, the workpiece temperature drops rapidly, causing localized decomposition of the supersaturated solid solution, reducing the quenching effect, and significantly decreasing the post-treatment corrosion resistance. Therefore, general specifications recommend that the quenching transfer time be as short as possible.

[0003] Currently, the most commonly used methods for quenching workpieces are box furnaces and pit furnaces. Existing pit furnaces have drawbacks such as uneven heating during heat preservation, uneven austenitization at high temperatures, and poor quenching effect. In addition, the process of transferring the heat-preserved workpiece to the quenching medium is cumbersome, resulting in excessively long quenching transfer time and a decrease in quenching effect. Therefore, there is an urgent need to develop a quenching furnace that can ensure the heat preservation temperature and allow the workpiece to be quickly transferred to the quenching medium during heat preservation. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a device based on monitoring and coupling of the metal solidification heat process and real-time liquid quenching. This device ensures uniform heating of the workpiece placed in the furnace, thereby ensuring the holding temperature and ensuring that the held workpiece is quickly transferred to the quenching medium to ensure the quenching effect.

[0005] A device for real-time liquid quenching based on monitoring and coupling of the metal solidification thermal process is characterized in that it comprises:

[0006] The furnace body includes an outer wall and a central cavity. The central cavity consists of a furnace opening and a furnace chamber from top to bottom. The portion of the outer wall corresponding to the furnace chamber consists of a heating layer, an insulation layer, and an outer protective layer from the inside to the outside. Several sets of thermocouples are arranged in the heating layer for heating the furnace chamber.

[0007] Stove lid;

[0008] Insulated base plate;

[0009] The support includes an upper plate and a vertical support. The vertical support is arranged around the upper plate, and a material feeding hole penetrating through the thickness direction is provided on the upper plate.

[0010] Quenching chamber;

[0011] The device includes a rotary drive mechanism, a transmission line, a support frame, and an adapter crucible. The support frame includes two side protrusions and a placement seat. In the initial state, the placement seat faces upward and is used to place the crucible. The rotary output end of the rotary drive mechanism is connected to one end of the transmission line, and the other end of the transmission line is connected to one of the side protrusions. The rotary output end of the rotary drive mechanism rotates to drive the placement seat to flip, thereby causing the crucible to flip and tip.

[0012] The surface of the furnace cover is fixed with a rotary drive mechanism. The surface of the furnace cover is provided with an avoidance notch corresponding to the position of the transmission line. The furnace cover is also provided with a second cover corresponding to the placement position of the crucible. When the second cover is open, the crucible is placed into the positioning notch of the placement seat by an external clamping rod. The support frame is located in the lower middle position of the furnace chamber, and the two side protrusions are respectively inserted and pivotally connected to the corresponding positions of the inner wall of the furnace chamber.

[0013] The furnace body is located on the upper part of the upper plate and is supported at the bottom by four support rods. The top of the furnace body is covered with the furnace cover, and the bottom of the furnace body is provided with a heat-insulating base plate. The heat-insulating base plate is movable along the upper surface of the upper plate. A quenching chamber is provided below the lower surface of the upper plate. The inlet of the quenching chamber covers the discharge hole. After the heat-insulating base plate is removed from the bottom of the furnace body, the furnace chamber of the furnace body is connected to the quenching chamber through the discharge hole.

[0014] Its further features are:

[0015] The upper surface of the upper plate is also provided with a controller part, and the furnace cover is also provided with at least one temperature sensor insertion hole. The temperature sensor extends into the furnace through the temperature sensor insertion hole. The controller part is also used to control the heating temperature of the thermocouple. The controller part uses the temperature feedback from the temperature sensor to reliably control the heating temperature of the thermocouple.

[0016] The rotary drive mechanism is specifically a swing cylinder. The swing cylinder drives the output wheel to rotate by extending and retracting the cylinder, thereby driving the placement seat to flip or reset.

[0017] It also includes a gas output mechanism, which includes an external inert gas source and a pressure reducing valve. The furnace cover is also provided with an air inlet. The inert gas source is sent into the central cavity of the furnace body through the pressure reducing valve. The inert gas ensures that the aluminum liquid will not be oxidized during the heating and heat preservation process.

[0018] The furnace chamber is also provided with a gas recovery hole. The gas recovery hole is connected to the gas cooling device through a recovery pipeline and then enters the air inlet on the furnace cover or is recovered by the inert gas recovery tank, which ensures the reuse of inert gas and reduces costs.

[0019] The upper surface of the upper plate is provided with a set of guide rails corresponding to the moving area of ​​the insulation base plate. The corresponding side of the insulation base plate is provided with a slider. The slider is supported by the guide rails to form a sliding connection. When the insulation base plate is closed, the insulation base plate completely covers the furnace area.

[0020] A flange is formed on the outer periphery of the bottom of the furnace body. The bottom of the flange is supported on the upper plate by a number of arranged support rods, and the position of the support rods does not interfere with the movement of the insulation base plate.

[0021] Preferably, the transmission line is a chain, with a first sprocket fixedly mounted on one of the side protruding rods, and a second sprocket fixedly mounted on the rotation output end of the rotary drive mechanism. The second sprocket is positioned directly above the height of the first sprocket, and the first sprocket is connected to the second sprocket via a chain. The chain drive ensures stable and reliable transmission operation in high-temperature environments, and the position of the chain does not interfere with the placement of the crucible.

[0022] The diameter of the furnace opening is smaller than the diameter of the furnace chamber. The diameter of the furnace opening is sufficient to ensure the reliable placement of the crucible and the normal transmission of the chain. The diameter of the furnace chamber is sufficient to ensure that the crucible can be tilted or overturned.

[0023] The bottom of the quenching chamber is supported by a second bracket, and water is placed inside the quenching chamber for quenching operations.

[0024] With the structure of this utility model, the heat-insulating base plate is moved to the bottom of the furnace chamber, forming a closed furnace body structure. The second cover is opened, and the crucible containing aluminum alloy is placed into the positioning notch of the placement seat through the external clamping rod. Then the second cover is closed, and the furnace chamber is heated and kept at the corresponding temperature through the thermocouple. Then the heat-insulating base plate is removed from the furnace chamber area. At the same time, the rotation output end of the rotation drive mechanism rotates, causing the placement seat to flip and thus causing the crucible to flip and tilt. The crucible and the workpiece are poured into the quenching medium in the quenching chamber through the feeding hole for quenching. This ensures that the workpiece placed in the furnace chamber is heated evenly, thus ensuring the heat preservation temperature, and ensuring that the heat-preserved workpiece is quickly transferred to the quenching medium to ensure the quenching effect.

Detailed Implementation

[0031] A device based on the monitoring and coupling of the metal solidification thermal process and real-time liquid quenching, see [link to device].

The rotary output end of the rotary drive mechanism 61 is connected to one end of the transmission line 62, and the other end of the transmission line 62 is connected to one of the side protrusions 65. The rotary output end of the rotary drive mechanism 61 rotates to drive the placement seat 66 to flip, thereby causing the crucible 64 to flip and tip.

[0035] A rotary drive mechanism 61 is fixed on the surface of the furnace cover 20. An avoidance notch is opened on the surface of the furnace cover 20 corresponding to the position of the transmission line 62. A second cover 21 is also provided on the furnace cover 20 corresponding to the placement position of the crucible 64. When the second cover 21 is open, the crucible 64 is placed into the positioning notch of the placement seat 66 by an external clamping rod (not shown in the figure, but can be designed reasonably according to the requirements). The support frame 63 is located in the middle and lower position of the furnace chamber 14, and the two side protrusions 65 are respectively inserted into the corresponding positions of the inner wall of the furnace chamber 14.

After the heat-insulating base plate 30 is removed from the bottom of the furnace body 10, the furnace chamber 14 of the furnace body 10 is connected to the quenching chamber 60 through the discharge hole 43.

[0037] In specific implementation, a controller section 80 is also provided on one side of the upper surface of the upper plate 41, and at least one temperature sensor insertion hole is provided on the furnace cover 20. The temperature sensor extends into the furnace through the temperature sensor insertion hole. The controller section 80 is also used to control the heating temperature of the thermocouple. The controller section 80 uses the temperature fed back by the temperature sensor to reliably control the heating temperature of the thermocouple.

[0038] The rotary drive mechanism 61 is specifically a swing cylinder. The swing cylinder drives the output wheel to rotate by extending and retracting the cylinder, thereby driving the placement seat 66 to flip or reset.

[0039] In specific implementation, it also includes a gas output mechanism 90, which includes an external inert gas source 91 and a pressure reducing valve 92. An air inlet is also provided on the furnace cover 20. The inert gas source 91 is sent into the central cavity of the furnace body 10 through the pressure reducing valve 92. The inert gas ensures that the aluminum liquid will not be oxidized during the heating and heat preservation process.

[0040] The furnace chamber 14 is also provided with a gas recovery hole. The gas recovery hole is connected to the gas cooling device 94 through the recovery pipe 93 and then into the air inlet on the furnace cover 20 or is recovered by the inert gas recovery tank, which ensures the reuse of inert gas and reduces costs.

[0041] In specific implementation, a set of guide rails 31 arranged on both sides is provided on the upper surface of the upper plate 41 corresponding to the moving area of ​​the insulation base plate 30. A slider 32 is provided on the corresponding side of the insulation base plate. The slider 32 is supported by the guide rails 31 to form a sliding connection. When the insulation base plate 30 is closed, the insulation base plate 30 completely covers the furnace chamber 14 area.

[0042] In practice, a flange 101 is formed on the outer periphery of the bottom of the furnace body 10. The bottom of the flange 101 is supported on the upper plate 41 by a number of arranged support rods 70, and the position of the support rods 41 does not interfere with the movement of the insulation base plate 30.

[0043] In a preferred embodiment, the transmission line 62 is a chain, with a first sprocket 67 fixedly mounted on one of the side protrusions 65, and a second sprocket 68 fixedly mounted on the rotation output end of the swing cylinder. The second sprocket 68 is positioned directly above the height of the first sprocket 67. The first sprocket 67 is connected to the second sprocket 68 via a chain. The chain drive ensures stable and reliable transmission operation in high-temperature environments, and the position of the chain does not interfere with the placement of the crucible 64.

[0044] In practice, the furnace body 10 is cylindrical, the diameter of the furnace opening 13 is smaller than the diameter of the furnace chamber 14, the diameter of the furnace opening 13 is sufficient to ensure the reliable placement of the crucible 64 and the normal transmission of the chain, and the diameter of the furnace chamber 14 is sufficient to ensure that the crucible 64 is overturned.

[0045] The bottom of the quenching chamber 50 is supported by the second bracket 51, and water is placed inside the quenching chamber 50 for quenching operations.

[0046] Its working principle is as follows: The insulating base plate is moved to the bottom of the furnace chamber to form a closed furnace body structure. The second cover is opened, and the crucible containing aluminum alloy is placed into the positioning notch of the placement seat through the external clamping rod. Then the second cover is closed. The furnace chamber is heated and held at the corresponding temperature through the thermocouple. Then the insulating base plate is removed from the furnace chamber area. At the same time, the rotation output end of the rotation drive mechanism rotates to drive the placement seat to flip, which in turn drives the crucible to flip and tilt. The crucible and the workpiece are poured into the quenching medium in the quenching chamber through the feeding hole for quenching. This can ensure that the workpiece placed in the furnace chamber is heated evenly, thereby ensuring the holding temperature, and ensuring that the workpiece after holding is quickly transferred to the quenching medium to ensure the quenching effect.
