Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profile processing technology, specifically to an irregular aluminum extrusion die with a water-cooling mechanism. Background Technology
[0002] Extrusion dies are commonly used for processing irregular aluminum alloy profiles. Their structure is relatively simple, consisting of two parts: a die base and a die template. The die template is fitted inside the die base. During operation, a hydraulic mechanism pushes a heat-treated aluminum rod into the die base and through the die template to be extruded into a specific shape.
[0003] In conventional aluminum extrusion, the die and extruded material primarily rely on natural cooling through exposure to air. This method is acceptable for simple, thick-walled profiles, but if the workpiece itself requires high surface quality, such as mirror finish, electrophoretic finish, or powder-coated profiles, excessively high die temperatures can lead to scratches, pitting, and cracks (coarse surface grains) on the aluminum surface, affecting the yield.
[0004] Now, a novel extrusion die for irregularly shaped aluminum materials with a water-cooling mechanism is proposed to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a special-shaped aluminum extrusion die with a water-cooling mechanism to solve the problem mentioned in the background art of not being able to perform preliminary cooling of the workpiece.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an irregular aluminum extrusion die with a water-cooling mechanism, including an extrusion die base, two sets of horizontal flow dies are fixedly connected to the right side inside the extrusion die base, a die fixing base is integrally formed at the bottom end of the extrusion die base, and a water-cooling component that can be cooled by water is provided on the left side of the extrusion die base.
[0007] The water-cooling assembly includes an aluminum alloy outer shell, which is located on the left side of the extrusion die base. A flange is welded to the right side of the aluminum alloy outer shell. An inner cylinder shell is fixedly connected inside the aluminum alloy outer shell, and a copper coil is wound around the outside of the inner cylinder shell. A first interface and a second interface are respectively provided on both sides of the bottom of the aluminum alloy outer shell. A low-temperature water outlet tank and a high-temperature reflux tank are provided below the extrusion die base. Multiple sets of aluminum alloy square flat tubes are fixedly connected between the low-temperature water outlet tank and the high-temperature reflux tank. A fan mounting bracket is fixedly connected to the right side of the high-temperature reflux box, and a powerful fan is fixedly installed between the two sets of fan mounting brackets. A PLC controller is fixedly installed at the front end of the low-temperature water outlet box. A water inlet is provided at the top of the low-temperature water outlet box, and a water outlet is provided at the bottom of the left side of the low-temperature water outlet box. A water return port is provided at the top of the left side of the high-temperature reflux box. A reflux pipe is movably connected between the water return port and the first interface. A circulation pump is fixedly installed on the left side of the water outlet, and a water inlet pipe is movably connected between the circulation pump and the second interface.
[0008] As a further technical solution of this utility model, the low-temperature water outlet tank, the high-temperature reflux tank, and the aluminum alloy square flat tube are internally connected, and there is a distance between the aluminum alloy square flat tube and the powerful fan.
[0009] As a further technical solution of this utility model, the copper coil, the first interface, and the second interface are internally connected, and the powerful fan, the PLC controller, and the circulating pump are electrically connected.
[0010] As a further technical solution of this utility model, the shape and size of the advection mold and the inner cylinder shell are adapted to each other, and the extrusion mold base and the flange are fixedly connected by bolts.
[0011] As a further technical solution of this utility model, multiple sets of aluminum alloy fins are vertically fixedly connected between each pair of the aluminum alloy square flat tubes, and the left and right sides of the aluminum alloy square flat tubes and aluminum alloy fins are flush.
[0012] As a further technical solution of this utility model, a sensor mounting bracket is fixedly connected to the left side of the top of the aluminum alloy outer shell, a sensor host is fixedly installed on the right side of the sensor mounting bracket, an infrared temperature sensor is fixedly connected to the top of the sensor mounting bracket, a sensor wiring is movably connected between the sensor host and the infrared temperature sensor, and the sensor host and the infrared temperature sensor are electrically connected.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the irregular aluminum extrusion die with water cooling mechanism not only realizes the function of water cooling at the discharge port, but also realizes the function of accelerating heat loss, and also realizes the function of easy monitoring of workpiece temperature.
[0014] (1) By setting up a low-temperature water outlet tank, a high-temperature reflux tank, an aluminum alloy square flat tube, a fan mounting bracket, a powerful fan, a PLC controller, a water inlet, a water outlet, a water return outlet, a reflux pipe, a circulating pump, a water inlet pipe, an aluminum alloy outer shell, a flange, an inner cylinder shell, a copper coil, a first interface, and a second interface, during use, the heat-treated aluminum rod is fed to the right opening of the extrusion die under the action of the feeding mechanism. The hydraulic mechanism pushes the aluminum rod into the extrusion die. The aluminum rod is shaped by two sets of parallel flow dies, forming a special-shaped aluminum profile that is discharged from the left. The aluminum profile itself has a high temperature. When passing through the inside of the aluminum alloy outer shell, it circulates... The ring pump continuously pumps cold water from the low-temperature outlet tank to the inlet pipe and then to the copper coil. The copper coil lowers the temperature of the inner shell, placing the profile passing through the inner shell in a relatively low-temperature environment, causing its surface temperature to drop rapidly. After absorbing heat, the cold water flows back to the high-temperature return tank through the return pipe and then enters the low-temperature outlet tank through the aluminum alloy square flat tube. When passing through the aluminum alloy square flat tube, the powerful fan continuously blows air through it, and the high-speed airflow allows the heat of the aluminum alloy square flat tube to be quickly dissipated, causing the water temperature to drop rapidly and forming cold water, thus realizing the function of water cooling at the outlet.
[0015] (2) By setting up aluminum alloy square flat tubes, fan mounting brackets, powerful fans and aluminum alloy fins, when in use, the dense aluminum alloy fins welded between the two aluminum alloy square flat tubes can further accelerate the heat loss on the surface of the aluminum alloy square flat tubes, increase the efficiency of air carrying away heat, and make the water temperature drop faster, thus realizing the function of accelerating heat loss.
[0016] (3) By setting up a sensor mounting bracket, a sensor host, an infrared temperature sensor and sensor wiring, when in use, the cooled shaped aluminum alloy material passes through the inner cylinder shell and is discharged outward. The infrared temperature sensor on the sensor mounting bracket keeps monitoring the temperature of the discharged profile and feeds the data back to the display screen of the sensor host, which is convenient for staff to view. When the temperature is abnormal, timely intervention and inspection can be carried out, thus realizing the function of easy monitoring of workpiece temperature. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Please refer to Figure 1-4 An extrusion die for irregular aluminum material with a water cooling mechanism includes an extrusion die base 1, two sets of horizontal flow dies 2 are fixedly connected to the right side inside the extrusion die base 1, a die fixing base 3 is integrally formed at the bottom end of the extrusion die base 1, and a water cooling component that can be cooled by water is provided on the left side of the extrusion die base 1.
[0024] Please see Figure 1-4A water-cooled aluminum extrusion die also includes a water-cooling assembly, which includes an aluminum alloy outer shell 16. The aluminum alloy outer shell 16 is located on the left side of the extrusion die base 1, and a flange 17 is welded to the right side of the aluminum alloy outer shell 16. An inner cylinder shell 18 is fixedly connected inside the aluminum alloy outer shell 16, and a copper coil 19 is coiled around the outside of the inner cylinder shell 18. A first interface 20 and a second interface 21 are respectively provided on both sides of the bottom of the aluminum alloy outer shell 16. A low-temperature water outlet tank 4 and a high-temperature reflux tank 5 are provided below the extrusion die base 1. Multiple sets of aluminum alloy square tubes are fixedly connected between the low-temperature water outlet tank 4 and the high-temperature reflux tank 5. A flat tube 6, a fan mounting bracket 7 is fixedly connected to the right side of the low temperature water outlet tank 4 and the high temperature reflux tank 5 respectively, a powerful fan 8 is fixedly installed between the two sets of fan mounting brackets 7, a PLC controller 9 is fixedly installed at the front end of the low temperature water outlet tank 4, a water inlet 10 is set at the top of the low temperature water outlet tank 4, a water outlet 11 is set at the bottom of the left side of the low temperature water outlet tank 4, a water return port 12 is set at the top of the left side of the high temperature reflux tank 5, a reflux pipe 13 is movably connected between the water return port 12 and the first interface 20, a circulation pump 14 is fixedly installed on the left side of the water outlet 11, and a water inlet pipe 15 is movably connected between the circulation pump 14 and the second interface 21.
[0025] The low-temperature water outlet tank 4, the high-temperature reflux tank 5, and the aluminum alloy square flat tube 6 are internally connected. There is a distance between the aluminum alloy square flat tube 6 and the powerful fan 8. The copper coil 19, the first interface 20, and the second interface 21 are internally connected. The powerful fan 8, the PLC controller 9, and the circulating pump 14 are electrically connected. The shape and size of the internal parts of the horizontal flow mold 2 and the inner cylinder shell 18 are compatible. The extrusion mold base 1 and the flange 17 are fixedly connected by bolts to facilitate water cooling of the profile.
[0026] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, when the aluminum profile passes through the aluminum alloy outer shell 16, the circulating pump 14 continuously pumps the cold water in the low-temperature outlet tank 4 through the inlet pipe 15 to the copper coil 19. The copper coil 19 lowers the temperature of the inner shell 18, so that the profile passing through the inner shell 18 is in a relatively low-temperature environment, causing its surface temperature to drop rapidly. After absorbing heat, the cold water flows back to the high-temperature return tank 5 along the return pipe 13, and enters the low-temperature outlet tank 4 along the aluminum alloy square flat tube 6. When passing through the aluminum alloy square flat tube 6, the powerful fan 8 continuously blows air through it, and the high-speed airflow can cause the heat of the aluminum alloy square flat tube 6 to be quickly lost, causing the water temperature to drop rapidly and forming cold water.
[0027] Multiple sets of aluminum alloy fins 22 are vertically fixed between each pair of aluminum alloy square flat tubes 6. The left and right sides of the aluminum alloy square flat tubes 6 and aluminum alloy fins 22 are flush, which further accelerates the cooling.
[0028] Specifically, such as Figure 1 and Figure 2 As shown, the dense aluminum alloy fins 22 welded between each pair of aluminum alloy square flat tubes 6 can further accelerate the heat loss from the surface of the aluminum alloy square flat tubes 6, increase the efficiency of air carrying away heat, and make the water temperature drop faster.

A sensor host 24 is fixedly installed on the right side of the sensor mounting bracket 23. An infrared temperature sensor 25 is fixedly connected to the top of the sensor mounting bracket 23. A sensor wiring 26 is movably connected between the sensor host 24 and the infrared temperature sensor 25. The sensor host 24 and the infrared temperature sensor 25 are electrically connected to facilitate monitoring of the profile temperature.
[0030] Specifically, such as Figure 1 and Figure 3 As shown, the cooled profiled aluminum alloy material passes through the inner cylinder shell 18 and is discharged outward. The infrared temperature sensor 25 on the sensor mounting bracket 23 keeps monitoring the temperature of the discharged profile and feeds the data back to the display screen of the sensor host 24.
[0031] Working principle: When this utility model is in use, firstly, the heat-treated aluminum rod is fed to the right opening of the extrusion die 1 by the feeding mechanism. The hydraulic mechanism pushes the aluminum rod into the extrusion die 1. The aluminum rod is shaped by two sets of parallel flow dies 2, forming a special-shaped aluminum profile that is discharged from the left. The aluminum profile itself is at a high temperature. When it passes through the aluminum alloy outer shell 16, the circulation pump 14 continuously pumps the cold water in the low-temperature outlet water tank 4 to the inlet pipe 15 and then to the copper coil 19. The copper coil 19 lowers the temperature of the inner cylinder shell 18, so that the profile passing through the inner cylinder shell 18 is in a relatively low-temperature environment, causing its surface temperature to drop rapidly. After absorbing the heat, the cold water flows back to the high-temperature return box 5 along the return pipe 13 and enters the low-temperature outlet water tank 4 along the aluminum alloy square flat tube 6. When passing through the aluminum alloy square flat tube 6, the powerful fan 8 continuously blows air through it. The high-speed airflow can cause the heat of the aluminum alloy square flat tube 6 to be quickly dissipated, causing the water temperature to drop rapidly and forming cold water. The dense aluminum alloy fins 22 welded between each pair of aluminum alloy square flat tubes 6 can further accelerate heat loss from the surface of the aluminum alloy square flat tubes 6, increase the efficiency of air carrying away heat, and make the water temperature drop faster. The cooled irregular-shaped aluminum alloy material passes through the inner cylinder shell 18 and is discharged outward. The infrared temperature sensor 25 on the sensor mounting bracket 23 keeps monitoring the temperature of the discharged profile and feeds the data back to the display screen of the sensor host 24 for easy viewing by the staff, and can intervene in time to check when the temperature is abnormal.
