Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing, in particular to an aluminum alloy profile extrusion molding device. Background Art

[0002] Aluminum alloy profile extrusion equipment is a key piece of equipment used in the production of aluminum alloy profiles. Extrusion involves heating an aluminum alloy billet to an appropriate temperature and then forcing it through a specifically shaped die to obtain the desired cross-sectional shape. This process is commonly used to manufacture various aluminum alloy profiles, such as window and door frames, railway vehicle components, and aerospace parts.

[0003] A search revealed an existing patent (publication number: CN210966427U) that discloses an aluminum alloy profile extrusion molding device, comprising a base and a frame. The frame is fixedly connected to the base. The top of the base is sequentially equipped with an extrusion cylinder, an extrusion box, an ingot receiving box, a mold receiving box, and a cooling box. The piston rod end of the extrusion cylinder is fixedly connected to the extrusion box. The extrusion rod is fixedly connected to the end of the extrusion box away from the extrusion cylinder. The ingot receiving box has a horizontal opening for placing the aluminum ingot. The mold receiving box is equipped with a mold. A shearing mechanism is mounted on the frame directly above the mold's demolding point. A conveyor belt for conveying the aluminum alloy profile is horizontally mounted within the cooling box. A water spray tray for cooling the aluminum alloy profile is fixedly connected to the top wall of the cooling box. The water spray tray is equipped with a nozzle. These improvements enable rapid cooling and drying of the aluminum alloy profile, improving production efficiency and preventing burns to workers from the high-temperature aluminum alloy profile.

[0004] However, in the actual use of the above solution, the mold replacement function is not available, and the inability to quickly replace the mold has a number of negative effects on the aluminum alloy profile extrusion molding device. First, it will lead to low production efficiency and increased production costs, because replacing the mold requires a long downtime and adjustment cycle, which increases labor costs and scrap rates. Secondly, product quality and stability may be affected, because the equipment needs to be readjusted after each replacement, which may lead to quality fluctuations and increased production losses. In addition, the inability to quickly adapt to changes in market demand limits the flexibility of the production line and the reliability of customer delivery time. Therefore, optimizing the mold replacement process is a key measure to improve the efficiency and competitiveness of the device, including the use of a quick replacement system and improving the skills of operators.

[0005] To this end, the utility model provides an aluminum alloy profile extrusion forming device. Utility Model Content

The first hydraulic rod 2 is slidably connected to the inner side of the first hydraulic rod 2, and the push rod 21 is driven by the first hydraulic rod 2 to move left and right. An aluminum rod 7 is provided on the right side of the push rod 21, and the aluminum rod 7 is slidably connected to the shaping plate 61. The aluminum rod 7 is driven to move to the right by the push rod 21, so that the aluminum rod 7 is extruded and shaped by the shaping plate 61.

[0028] The sealing assembly includes a limiting cylinder 31, a fixing plate 3 is fixedly connected to the middle side of the top of the main frame 1, and the fixing plate 3 is supported and fixed by the main frame 1, and the left side of the fixing plate 3 is fixedly connected to the limiting cylinder 31, and the limiting cylinder 31 is fixed by the fixing plate 3, and a second sliding groove 33 facing front and back is opened on the inner side of the limiting cylinder 31, and the middle end of the inner side of the second sliding groove 33 is fixedly connected to the sliding rod 34, and the sliding rod 34 is fixed by the limiting cylinder 31, and the outer side of the middle end of the sliding rod 34 is slidably connected to the first slider 35, and the first slider 35 is limited by the sliding rod 34, and the left side of the first slider 35 is fixedly connected to the first spring 36, and one end of the left side of the first spring 36 is fixedly connected to the left inner wall of the second sliding groove 33, and the first slider 35 and the limiting cylinder 31 are connected by the first spring 36.

[0029] The middle end of the inner side of the limiting cylinder 31 is provided with a first sliding groove 32, and the inner side of the first sliding groove 32 is slidably connected to the sealing cylinder 4. The sealing cylinder 4 is limited by the first sliding groove 32, and the sealing cylinder 4 is fixedly connected to the first slider 35.

[0030] The outer side of the push rod 21 is fixedly connected with a transmission rod 22 which is opposite to each other in the upper and lower directions. The transmission rod 22 is fixed by the push rod 21. The transmission rod 22 is slidably connected to the third slide groove 41. The push rod 21 is slidably connected to the sealing cylinder 4. When the push rod 21 moves to the right to extrude the aluminum rod 7, it also drives the transmission rod 22 to move to the right to push the second slider 43, thereby pushing the sealing cylinder 4 to the left with the second slider 43 as the stress point through the second spring 42. After the sealing cylinder 4 contacts the shaping plate 61, the transmission rod 22 continues to push the second slider 43 and squeeze the second spring 42, so that the sealing cylinder 4 is in close contact with the shaping plate 61 to ensure sealing.

[0031] The left side of the top end of the limiting cylinder 31 is fixedly connected to the door frame 5, and the door frame 5 is fixed by the limiting cylinder 31.

A support frame 13 is fixedly connected to the middle of the inner side of the top of the main frame 1, and a first slide rail 14 is fixedly connected to the inner side of the support frame 13. The support frame 13 and the first slide rail 14 are fixed at the same time by the main frame 1, so that the aluminum rod 7 can directly roll through the support frame 13 into the first slide rail 14.

[0033] Working principle: When the aluminum alloy profile extrusion forming device is running, the aluminum rod 7 first rolls down into the first slide rail 14 through the support frame 13, and then the first hydraulic rod 2 drives the push rod 21 and the transmission rod 22 to move to the left at the same time, pushing the aluminum rod 7 into the sealing cylinder 4, and then the second slider 43 is pushed by the transmission rod 22, thereby using the second spring 42 for transmission, and simultaneously pushing the sealing cylinder 4 to move to the left, and the sealing cylinder 4 drives the first slider 35 to move synchronously during the movement to the left, and the first spring 36 is compressed by the first slider 35, so that the sealing cylinder 4 and the shaping plate 61 are tightly fitted, and the push rod 21 squeezes the aluminum rod 7 during the continuous left movement, so that the aluminum rod 7 is shaped by the shaping plate 61 and comes out from the left. After the extrusion is completed, the first hydraulic rod 2 drives the push rod 21 and the transmission rod 22 to move right, and first pushes the second slider 43 to move right with the left inner wall of the third slide groove 41 as the stress point through the second spring 42. At the same time, the first spring 36 uses the left inner wall of the second slide groove 33 as the stress point to push the first slider 35 to the right, thereby driving the sealing cylinder 4 to move right synchronously through the first slider 35, leaking out the space on the left side of the limit cylinder 31, and then the fourth slide groove 52 drives the cutting knife 53 to move downward, cutting the unextended aluminum rod 7 waste, and the cut waste falls into the collection box 12 for collection, and then the new aluminum rod 7 is put into the first slide rail 14 and extruded again. When replacing the shaping plate 61, first fix the shaping plate 61 to be used on the shaping plate 61 through the first bolt 62, and then rotate the second bolt 63 connected to the inner thread groove 37 of the limit cylinder 31 in the opposite direction. After the connection between the second bolt 63 and the limit cylinder 31 is cancelled, the mounting plate 6 is pushed, and the shaping plate 61 is driven by the mounting plate 6 to move toward the limit cylinder 31, and then the second bolt 63 on the newly installed shaping plate 61 is connected to the corresponding thread groove 37 to complete the replacement.
