Description

Technical Field

[0001] This utility model relates to the field of aluminum profile tube technology, and in particular to a lightweight, high-strength aluminum profile tube extrusion molding device. Background Technology

[0002] The principle of aluminum tube extrusion molding is to place an aluminum billet in a mold cavity and apply strong pressure to force the aluminum billet out of the mold hole, thereby obtaining a part or semi-finished product with the desired cross-sectional shape, size and certain mechanical properties. This process involves heating the aluminum billet to a certain temperature to make it soft and malleable, and then extruding it through a specific mold to form the desired aluminum tube shape.

[0003] However, the lightweight high-strength aluminum profile tube extrusion molding device in the relevant technology still has shortcomings in use. After extrusion molding, it is inconvenient to cool the aluminum profile tube efficiently, which results in a long time for cooling and shaping, reducing production efficiency. In addition, it does not have a cutting mechanism, making it inconvenient to cut the cooled aluminum profile tube to the desired length. Therefore, we propose a lightweight high-strength aluminum profile tube extrusion molding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings mentioned above by proposing a lightweight, high-strength aluminum profile tube extrusion molding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lightweight, high-strength aluminum profile tube extrusion forming device includes a base, a mold, and a cooling cylinder. A left plate and a right plate are fixedly connected to the top of the base. An extrusion mechanism is provided on the left plate. A heating cylinder is fixedly sleeved inside the right plate, and a heating guide mechanism is provided inside the heating cylinder. Two left and right fixing rings are fixedly sleeved on the outside of the mold. The left fixing ring is fixedly connected to the outside of the heating cylinder by a screw, and the right fixing ring is fixedly connected to the outside of the cooling cylinder by a screw. A circulating cooling mechanism is provided between the base, the cooling cylinder, and the heating cylinder. A cutting mechanism is provided on one side of the cooling cylinder, and a tube outlet is opened on one side of the cooling cylinder.

[0007] As a preferred embodiment of this utility model, the extrusion mechanism includes a hydraulic cylinder fixedly connected to the left plate, and a plurality of telescopic rods are fixedly connected to the output shaft of the hydraulic cylinder, with an extrusion plate fixedly connected to one end of each telescopic rod.

[0008] As a preferred embodiment of this utility model, the heating guide mechanism includes a plurality of guide wheels rotatably connected to the inner wall of the heating cylinder, and a fan fixedly connected to the bottom of the heating cylinder. An annular heating cavity is provided inside the heating cylinder, and a plurality of heating tubes are fixedly connected to the inner walls on both sides of the annular heating cavity. A plurality of air outlet pipes are fixedly connected to the inner wall of the annular heating cavity.

[0009] In a preferred embodiment of this invention, the circulating cooling mechanism includes a water pump and a heat exchanger fixedly connected to the top of the base, an annular cooling chamber opened in the cooling cylinder, and a preheating chamber opened in the heating cylinder. The water pump and the heat exchanger are connected in communication. A cooling water pipe is fixedly connected between the water pump and the annular cooling chamber. A spiral guide plate is fixedly connected inside the annular cooling chamber. The annular cooling chamber and the preheating chamber are fixedly connected by the same connecting pipe. The preheating chamber and the heat exchanger are fixedly connected by the same return pipe.

[0010] As a preferred embodiment of this invention, a heat-conducting plate is fixedly connected to the front side of the heat exchanger, and a plurality of heat dissipation fins are fixedly connected to the front side of the heat-conducting plate.

[0011] As a preferred embodiment of this invention, a drain pipe is fixedly connected to one side of the water pump, and a water inlet pipe is fixedly connected to the top inner wall of the annular cooling chamber.

[0012] In a preferred embodiment of this invention, the cutting mechanism includes a support plate fixedly connected to one side of the cooling cylinder, a cylinder fixedly connected to the top of the support plate, a mounting bracket fixedly connected to the output shaft of the cylinder, a rotary motor fixedly connected to one side of the mounting bracket, and a cutting blade fixedly connected to the output shaft of the rotary motor.

[0013] As a preferred embodiment of this invention, the output shaft of the rotary motor is rotatably connected to the inner walls of both sides of the mounting bracket.

[0014] In this utility model, a lightweight high-strength aluminum profile tube extrusion molding device is described. An aluminum rod is placed inside a heating cylinder. A fan blows air heated by several heating tubes into several air outlet pipes, ultimately heating the aluminum rod evenly. Once the specified temperature is reached, a hydraulic cylinder is activated. The output shaft of the hydraulic cylinder extends multiple telescopic rods and drives the extrusion plate to move to the right, extruding the heated aluminum rod into the mold. The mold core and cavity within the mold extrude the heated aluminum rod into an aluminum profile tube. Continued extrusion pushes the aluminum profile tube into the outlet hole. Because the mold has a left and right fixing ring on its outer side, a screw can be used to install molds of corresponding specifications between the heating and cooling cylinders, allowing for the extrusion molding of aluminum tubes of different sizes and improving the device's versatility.

[0015] In this utility model, a lightweight high-strength aluminum profile tube extrusion molding device is described. A water pump draws cold water from the heat exchanger into a cold water supply pipe, which then flows into the annular cooling chamber. A spiral guide plate ensures the cold water flows spirally along the guide plate, extending its time within the annular cooling chamber. This allows the cold water to more fully absorb heat from the aluminum tube, significantly improving cooling efficiency and effectiveness. The heated cold water then flows through a connecting pipe into a preheating chamber, where it heats the heating cylinder for preheating the next aluminum rod, preventing heat waste. The water then flows back through a return pipe to the heat exchanger for further cooling, creating a cyclical cooling system that improves cooling efficiency and effectiveness. After cooling, once the aluminum tube of the desired length is extruded, a cylinder drives the cutting blade downwards, and a rotary motor drives the cutting blade to rotate, thus performing the downward cutting operation on the aluminum tube.

[0016] This utility model has a reasonable structural design. Through the circulating cooling mechanism, it can not only efficiently cool and shape the extruded aluminum tube, improving processing efficiency, but also preheat the next aluminum rod to avoid heat waste. After cooling and shaping, the aluminum tube can be cut, improving the practicality of the device. It also facilitates the disassembly and replacement of molds of different specifications to extrude aluminum tubes of different specifications. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 A lightweight, high-strength aluminum profile tube extrusion molding device includes a base 1, a mold 10, and a cooling cylinder 9. A left plate 2 and a right plate 19 are fixedly connected to the top of the base 1. An extrusion mechanism is provided on the left plate 2. A heating cylinder 6 is fixedly sleeved inside the right plate 19. A heating guide mechanism is provided inside the heating cylinder 6. Two left fixing rings 11 and a right fixing ring 12 are fixedly sleeved on the outside of the mold 10. The left fixing ring 11 is fixedly connected to the outside of the heating cylinder 6 by a screw. The right fixing ring 12 is fixedly connected to the outside of the cooling cylinder 9 by a screw. A circulating cooling mechanism 7 is provided between the base 1, the cooling cylinder 9, and the heating cylinder 6. A cutting mechanism 8 is provided on one side of the cooling cylinder 9. A tube outlet hole 13 is opened on one side of the cooling cylinder 9.

[0024] Furthermore, refer to Figure 1 and Figure 2 As shown, the extrusion mechanism includes a hydraulic cylinder 3 fixedly connected to the left plate 2. Multiple telescopic rods 4 are fixedly connected to the output shaft of the hydraulic cylinder 3. An extrusion plate 5 is fixedly connected to one end of the multiple telescopic rods 4. The heating guide mechanism includes several guide wheels 14 rotatably connected to the inner wall of the heating cylinder 6, and a fan 17 fixedly connected to the bottom of the heating cylinder 6. An annular heating chamber 15 is opened inside the heating cylinder 6. Several heating pipes 16 are fixedly connected to the inner walls on both sides of the annular heating chamber 15. Several air outlet pipes 18 are fixedly connected to the inner wall of the annular heating chamber 15.

[0025] Using the above scheme: the aluminum rod is placed in the heating cylinder 6, and the air heated by the heating tubes 16 is blown into the air outlets 18 by the fan 17. Finally, the air is blown out from the air outlets 18 to heat the aluminum rod evenly. When the specified temperature is reached, the hydraulic cylinder 3 is activated. The output shaft of the hydraulic cylinder 3 drives the extension of the multi-section telescopic rod 4 and drives the extrusion plate 5 to move to the right to extrude the heated aluminum rod into the mold 10. The mold core and mold cavity in the mold can extrude the heated aluminum rod into an aluminum profile tube.

[0026] Furthermore, refer to Figure 1-3 As shown, the circulating cooling mechanism 7 includes a water pump 701 and a heat exchanger 704 fixedly connected to the top of the base 1, an annular cooling chamber 711 opened in the cooling cylinder 9, and a preheating chamber 710 opened in the heating cylinder 6. The water pump 701 is connected to the heat exchanger 704. A cooling water pipe 703 is fixedly connected between the water pump 701 and the annular cooling chamber 711. A spiral guide plate 712 is fixedly connected inside the annular cooling chamber 711. The annular cooling chamber 711 and the preheating chamber 710 are fixedly connected by the same connecting pipe 708. The preheating chamber 710 and the heat exchanger 704 are fixedly connected by the same return pipe 709.

[0027] The above scheme employs the following method: Water pump 701 draws the chilled water from heat exchanger 704 into cooling water supply pipe 703, which then flows into annular cooling chamber 711. The spiral guide plate 712 causes the chilled water to flow spirally along it, extending its time within the annular cooling chamber 711. This allows the chilled water to more fully absorb heat from the aluminum tubes, significantly improving cooling efficiency and effectiveness. The chilled water, having absorbed heat, flows from connecting pipe 708 into preheating chamber 710, where it heats heating cylinder 6 to preheat the next aluminum rod, preventing heat waste. The water then flows from the left along return pipe 709 back into heat exchanger 704 for further cooling, thus creating a cyclical cooling system with improved cooling effect and higher efficiency.

[0028] Furthermore, a heat-conducting plate 706 is fixedly connected to the front side of the heat exchanger 704, and several heat dissipation fins 705 are fixedly connected to the front side of the heat-conducting plate 706, which facilitates efficient heat dissipation of the heat exchanger 704, making its cooling effect better and improving the cooling efficiency.

[0029] Furthermore, a drain pipe 702 is fixedly connected to one side of the water pump 701, and a water inlet pipe 707 is fixedly connected to the top inner wall of the annular cooling chamber 711, which facilitates the regular replacement of water.

[0030] Furthermore, refer to Figure 1 , Figure 3 and Figure 4As shown, the cutting mechanism 8 includes a support plate 81 fixedly connected to one side of the cooling cylinder 9. A cylinder 82 is fixedly connected to the top of the support plate 81. A mounting bracket 83 is fixedly connected to the output shaft of the cylinder 82. A rotary motor 84 is fixedly connected to one side of the mounting bracket 83. A cutting blade 85 is fixedly connected to the output shaft of the rotary motor 84. The output shaft of the rotary motor 84 is rotatably connected to the inner walls on both sides of the mounting bracket 83.

[0031] Using the above scheme: After cooling, when the aluminum tube of the corresponding length is extruded, the cylinder 82 drives the cutting blade 85 to move downward, and the rotary motor 84 drives the cutting blade 85 to rotate, thereby performing the downward cutting operation on the aluminum tube.

[0032] In this invention, during use, an aluminum rod is placed inside the heating cylinder 6. A fan 17 blows air heated by several heating tubes 16 into several air outlet pipes 18, ultimately heating the aluminum rod evenly. Once the specified temperature is reached, the hydraulic cylinder 3 is activated. The output shaft of the hydraulic cylinder 3 extends multiple telescopic rods 4 and drives the extrusion plate 5 to move to the right, extruding the heated aluminum rod into the mold 10. The mold core and cavity within the mold allow the heated aluminum rod to be extruded into an aluminum profile tube. Continuing to extrude the aluminum profile tube into the outlet hole 13. Because the mold 10 has a left fixing ring 11 and a right fixing ring 12 on its outer side, a mold 10 of the corresponding specification can be installed between the heating cylinder 6 and the cooling cylinder 9 using a screw, enabling the extrusion molding of aluminum tubes of different sizes and improving the versatility of the device.

[0033] The water pump 701 draws the chilled water from the heat exchanger 704 into the cooling water supply pipe 703, which then flows into the annular cooling chamber 711. The spiral guide plate 712 causes the chilled water to flow spirally along it, extending its time within the annular cooling chamber 711. This allows the chilled water to more fully absorb heat from the aluminum tubes, significantly improving cooling efficiency and effectiveness. The chilled water, having absorbed heat, flows from the connecting pipe 708 into the preheating chamber 710, where it heats the heating cylinder 6 to preheat the next aluminum rod, preventing heat waste. The water then flows from the left along the return pipe 709 back into the heat exchanger 704 for further cooling, thus creating a cyclical cooling system with better cooling effect and higher efficiency.

[0034] After cooling, once the aluminum tube of the corresponding length is extruded, the cylinder 82 drives the cutting blade 85 to move downwards, and the rotary motor 84 drives the cutting blade 85 to rotate, thereby performing the downward cutting operation on the aluminum tube.
