Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum profile extrusion equipment, and in particular relates to an extrusion equipment for aluminum profiles. Background Technology

[0002] With the booming development of modern industry and construction, aluminum profiles, with their excellent properties such as light weight, high strength, corrosion resistance and easy processing, are increasingly widely used in aerospace, rail transportation, building decoration, electronic equipment and many other fields. The market demand for aluminum profiles continues to rise. In the production process of aluminum profiles, the extrusion unit is the core production equipment, which is responsible for extruding the heated and softened aluminum alloy billet into profiles with specific cross-sectional shapes through the die. Its operation effect and processing accuracy directly determine the dimensional accuracy, surface quality and mechanical properties of aluminum profiles. Therefore, high-performance aluminum profile extrusion units are needed to ensure the production quality and efficiency of aluminum profiles.

[0003] However, existing extrusion equipment is not convenient for changing extrusion molds during use, resulting in long production interruption times, reduced overall production efficiency, and consequently affecting the size and cross-sectional shape of subsequent extruded profiles, increasing the rate of defective products. Utility Model Content

[0004] The purpose of this utility model is to provide an extrusion device for aluminum profiles. By setting up a mold section, it solves the problem that existing extrusion devices are inconvenient to replace the extrusion mold during use, resulting in long production interruption time, reduced overall production efficiency, and consequently affecting the size and cross-sectional shape of the extruded profiles and increasing the rate of defective products.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an extrusion device for aluminum profiles, comprising two support legs, and further comprising: an extrusion section mounted on the two support legs; a die section mounted on the top of the two support legs; a support section disposed on the left side of the die section; the die section includes an installation assembly mounted on the top of the support legs; and a fixing assembly mounted on the installation assembly; the installation assembly includes a mounting frame fixedly connected to the top of the two support legs, a fixing shell hinged to the mounting frame, and rectangular blocks fixedly connected to the front sides of both the mounting frame and the fixing shell; two L-shaped fixing rods fixedly connected to the bottom of the upper rectangular block, and two rectangular slots formed on the top of the lower rectangular block; a die component is disposed within the mounting frame; the two L-shaped fixing rods are mirror images of each other; and the die component includes a die disposed between the fixing shell and the mounting frame, providing initial positioning for die fixing.

[0006] Furthermore, the extrusion section includes a support plate fixedly connected to the top of the two support legs, a hydraulic cylinder fixedly connected to the top of the support plate, and a bracket fixedly connected to the top of the two support legs; the bracket is located between the support plate and the mounting bracket.

[0007] Furthermore, the support includes a support assembly mounted on top of the two support legs; a drive assembly disposed between the two support legs; and the drive assembly located below the support assembly.

[0008] Furthermore, the fixing component includes cylindrical slots respectively formed on the adjacent sides of the two rectangular slots. A spring telescopic rod is fixedly connected to each of the adjacent sides of the two cylindrical slots, and a circular plate is fixedly connected to each of the distant sides of the two spring telescopic rods. The two circular plates are slidably connected to the two cylindrical slots, and a fixing block is fixedly connected to each of the distant sides of the two circular plates. The two fixing blocks are adapted to two L-shaped fixing rods. A driving component is provided on the lower rectangular block. The two circular plates are located within the two cylindrical slots, and the two fixing blocks are triangular in shape and mirror images of each other. The driving component includes two rectangular holes formed on the front side of the lower rectangular block, and handles are slidably connected to each of the two rectangular holes. The two handles are fixedly connected to the two circular plates. The two rectangular slots are connected to the two cylindrical slots and are core components ensuring mold changing efficiency and fixing stability.

[0009] Furthermore, the support assembly includes guide rods fixedly connected to the tops of the two support legs respectively, and a support frame is slidably connected to the outer wall of the two guide rods. Two connecting blocks are fixedly connected to the bottom of the support frame. The support frame is located on the left side of the mounting frame to prevent deformation of the profile.

[0010] Furthermore, the drive assembly includes a bidirectional threaded rod rotatably connected to the front side of the rear support leg. The front side of the bidirectional threaded rod passes through the front support leg, and the bidirectional threaded rod is rotatably connected to the front support leg. Two drive blocks are threadedly connected to the outer wall of the bidirectional threaded rod. Each drive block is hinged with a drive rod, and the two drive rods are respectively hinged to two connecting blocks. A slide rod is fixedly connected between the two support legs, passing through the two drive blocks and slidably connected to them. A power component is installed on the front side of the front support leg. Two drive blocks are located at the threads on both sides of the bidirectional threaded rod, and the two drive blocks are mirror images of each other. The bidirectional threaded rod and the slide rod are parallel. The power component includes a motor fixedly connected to the front side of the front support leg. The output shaft of the motor is fixedly connected to the bidirectional threaded rod via a coupling, ensuring smooth adjustment and serving as the core transmission structure for flexible adaptation of the support height.

[0011] This utility model has the following beneficial effects: 1. By setting up the mold section, pressing the handle can disengage the fixing block from the L-shaped fixing rod, open the fixing shell and take out the mold; after replacing the mold, the fixing shell and the mounting frame are merged, and the L-shaped fixing rod presses the fixing block to reset and lock it, thus completing the mold fixing. This allows for quick mold replacement, reduces production interruption time, improves production efficiency, reduces the difficulty and intensity of manual operation, and reduces safety hazards and the risk of mold damage. 2. By setting up a support unit, after starting the motor, the bidirectional threaded rod drives the two drive blocks to move closer to each other along the slide rod. Through the drive rod and connecting block, the support frame is pushed to move smoothly along the guide rod. Reverse rotation lowers the position of the support frame, thereby adjusting it to be flush with the bottom of the aluminum profile extruded from the mold. This avoids deformation when the profile is just released from the mold due to its low strength. It ensures stable support for aluminum profiles of various specifications and guarantees the quality of product molding.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The two circular plates 223 are slidably connected to the two cylindrical grooves 221 respectively. Fixed blocks 224 are fixedly connected to the opposite sides of the two circular plates 223.

By setting up the mold part 2, the mold 216 can be quickly changed, reducing production interruption time, improving production efficiency, reducing the difficulty and intensity of manual operation, and reducing safety hazards and the risk of damage to the mold 216.

[0019] The support part 3 includes a support assembly 31, which is mounted on top of two support legs 111; and a drive assembly 32, which is disposed between the two support legs 111.

The output shaft of the motor 325 is fixedly connected to the bidirectional threaded rod 321 through a coupling. By setting the support part 3, the low strength of the part itself when it just leaves the mold can be avoided, thus preventing deformation and ensuring stable support for aluminum profiles of various specifications and guaranteeing the product forming quality.

[0020] It should be noted that the control of the hydraulic cylinder 113 and the motor 325 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.

[0021] A specific application of this embodiment is as follows: During use, pressing the two handles 226 causes them to slide within the two rectangular holes 225, bringing the two circular plates 223 closer together. The circular plates 223 then bring the two fixing blocks 224 closer together, compressing the two spring telescopic rods 222 and generating deformation and elasticity. The two fixing blocks 224 then move away from the two L-shaped fixing rods 214, opening the fixing shell 212 and causing it to rotate at the hinge point with the mounting bracket 211. Releasing the two handles 226 allows the two fixing blocks 224 to return to their original position under the elastic force of the two spring telescopic rods 222. Then... The mold 216 is removed from the fixed shell 212 and the mounting bracket 211, and a mold 216 of a different shape is replaced. Then, the fixed shell 212 and the mounting bracket 211 are merged. At this time, the fixed shell 212 drives the two L-shaped fixing rods 214 to move into the two rectangular slots 215 on the lower rectangular block 213 through the corresponding rectangular block 213. At this time, the two L-shaped fixing rods 214 press against the two fixing blocks 224 through the inclined surfaces, causing the two fixing blocks 224 to move away from each other. At this time, the two fixing blocks 224 push the two circular plates 223 to press against the two spring telescopic rods 222, causing the two spring telescopic rods 222 to generate elastic force. When the two L-shaped fixing rods 214 correspond to the two fixing blocks 224 respectively, the two fixing blocks 224 are reset and locked onto the two L-shaped fixing rods 214 under the elastic force of the two spring telescopic rods 222, thereby fixing the fixing shell 212 onto the mounting bracket 211 and installing the mold 216. Then, the motor 325 is started. At this time, the motor 325 drives the two drive blocks 322 to slide on the slide rod 324 and move closer to each other through the bidirectional threaded rod 321. Under the action of the parallel design of the slide rod 324 and the bidirectional threaded rod 321, the two drive blocks 322 drive the two drive rods 323 to move smoothly. At this time, the two drive rods 323 pushes the support frame 312 to slide on the two guide rods 311 through the corresponding connecting block 313. At this time, under the action of the two guide rods 311, the support frame 312 is ensured to move smoothly. Through the reverse operation process, the position of the support frame 312 is lowered, thereby adjusting the support frame 312 to be flush with the bottom of the aluminum profile extruded by the mold 216. Then, the heated aluminum rod is placed on the bracket 114, and then the hydraulic cylinder 113 is started. At this time, the output shaft of the hydraulic cylinder 113 pushes the aluminum rod to move towards the mold 216 and extrudes it. The formed aluminum profile will be removed through the support frame 312 and divided by subsequent cutting equipment.
