Description

An aluminum alloy profile extrusion forming device Technical Field

[0001] This utility model relates to the field of extrusion molding equipment technology, and in particular to an aluminum alloy profile extrusion molding equipment. Background Technology

[0002] Aluminum alloy profile extrusion is a process that uses high temperature and high pressure to plastically deform aluminum billets through a mold. It features high precision, high efficiency, and high material utilization, and can manufacture complex shapes to meet various design requirements. It is widely used in construction, automotive, aerospace, and electronics industries.

[0003] In the extrusion molding process of aluminum alloy profiles, there are two technical bottlenecks in the current production process: First, the residual aluminum slag in the forming mold is not cleaned before installation, which makes the aluminum ingot easily affected by the residue in the mold during the extrusion process, resulting in surface defects or abnormal extrusion resistance of the profile; Second, the existing cooling system adopts a flat conveyor belt combined with a large space and slow airflow for air cooling. This cooling method makes the heat dissipation efficiency of aluminum alloy profiles low, which not only prolongs the cooling cycle, but may also cause deformation risks in subsequent processing steps due to uneven temperature distribution. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides an aluminum alloy profile extrusion forming device to solve the problem of low cooling efficiency after aluminum alloy profile forming.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An aluminum alloy profile extrusion forming apparatus includes a base, a slide block slidably mounted on the top surface of the base, an extrusion rod mounted inside the slide block, the extrusion rod being driven by a hydraulic drive component inside the slide block, a front baffle mounted on one side of the base, a through extrusion port on the front baffle corresponding to the position of the extrusion rod, a die set inside the front baffle, the positions of the die inlet and outlet corresponding to the extrusion port, a sleeve mounted on the outer side of the front baffle via a support component, the sleeve being coaxially arranged with the extrusion port, a first air pump mounted on the top of the sleeve, the output port of the first air pump being connected to the interior of the sleeve.

[0007] A conveyor roller is installed in the lower part of the inner cavity of the sleeve.

[0008] A partition is installed on the upper part of the inner cavity of the casing. The partition has several through holes. The partition and the top of the inner cavity of the casing form a cavity. The output port of the first air pump is connected to the cavity.

[0009] A through opening is provided on the front baffle. A movable block is slidably installed at the bottom of the first opening via a linear slide rail. The mold is installed inside the movable block. A fourth opening is provided on the front and rear sides of the movable block corresponding to the inlet and outlet of the mold. A second air pump is installed on both sides of the extrusion port inside the front baffle. An air blowing hole is provided in the inner cavity of the second opening corresponding to the position of the second air pump. The output end of the second air pump is connected to the inner cavity of the first opening through the air blowing hole. A first opening is provided on the outer side of the front baffle corresponding to the position of the output port of the second air pump.

[0010] A third opening is provided at the top of the movable block.

[0011] An insulation seat is installed at the extrusion port on the inside of the front baffle. The aluminum rod is placed on the insulation seat, and the inner circle shape of the insulation seat corresponds to the outer circle shape of the aluminum rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Place the aluminum rod in the extrusion port inside the front baffle, start the hydraulic drive to move the extrusion rod forward and extrude the aluminum rod into the die. The aluminum rod undergoes plastic deformation through the die, and the extruded aluminum alloy profile is output through the extrusion port outside the front baffle and enters the sleeve. At the same time, start the first air pump. The gas flow of the first air pump helps to remove the heat from the surface of the profile, cools the formed profile, speeds up the shaping speed of the profile, and improves production efficiency.

[0014] 2. The rolling friction between the conveyor roller and the profile is much less than the sliding friction, which can effectively reduce the resistance when the profile moves, help protect the profile surface, and prevent scratches or damage caused by friction.

[0015] 3. The first air pump introduces gas into the cavity, and then distributes it evenly to various parts of the sleeve cavity through the through holes in the partition plate. This ensures that the formed profile is uniformly protected and cooled by the gas, avoiding uneven cooling or inconsistent gas pressure.

[0016] 4. After one extrusion molding is completed, the movable block is moved to the first opening on the outside of the front baffle through the linear slide rail. The second air pump is started. The second air pump blows the mold through the air hole, which can effectively remove the aluminum alloy debris, impurities and other residues in the mold, keep the mold clean, prevent the residue from accumulating in the mold and affecting the quality of the next extrusion molding, and extend the service life of the mold.

[0017] 5. The insulation base insulates the aluminum rod placed on it, maintaining a higher temperature before extrusion. Aluminum alloys exhibit better plasticity and flowability at higher temperatures, facilitating smooth extrusion into the die by the extrusion rod, reducing extrusion pressure, minimizing equipment wear, and improving profile forming quality while reducing defects. Furthermore, the inner circle of the insulation base corresponds to the outer circle of the aluminum rod, providing positioning and ensuring the rod is correctly positioned during extrusion, aligned with the axes of the extrusion rod and die, guaranteeing smooth extrusion and dimensional accuracy of the profile.

[0027] A partition 15 is installed on the upper part of the inner cavity of the sleeve 12. The partition 15 has several through holes 16. The partition 15 and the top of the inner cavity of the sleeve 12 form a cavity 14. The output port of the first air pump 11 is connected to the cavity 14.

[0028] A through opening 8 is provided on the front baffle 5. A movable block 7 is slidably mounted on the bottom of the first opening 8 via a linear slide rail 9. The mold 17 is installed inside the movable block 7. A fourth opening 22 is provided on the front and rear sides of the movable block 7 corresponding to the inlet and outlet of the mold 17. A second air pump 20 is installed on both sides of the extrusion port 6 inside the front baffle 5. An air blowing hole 19 is provided in the inner cavity of the second opening 10 corresponding to the position of the second air pump 20. The output end of the second air pump 20 is connected to the inner cavity of the first opening 8 through the air blowing hole 19. A first opening 8 is provided on the outer side of the front baffle 5 corresponding to the position of the output port of the second air pump 20.
