Description

Technical Field

[0001] This utility model relates to the field of aluminum processing technology, and in particular to an aluminum extrusion press. Background Technology

[0002] Aluminum extrusion is one of the core processes in the modern aluminum processing industry. During this process, the high-temperature aluminum material extruded from the die needs to undergo timely cooling to fix its internal structure and obtain the required mechanical properties. The choice of cooling method in this stage directly determines the quality, precision, and production efficiency of the final product.

[0003] For example, Chinese patent CN223043837U discloses an aluminum extrusion press, relating to the field of extrusion press technology. It includes a base, with a positioning component fixedly connected to the top of the base near the left side. The positioning component includes a support frame, a motor fixedly connected to the inner wall of one side of the support frame, a lead screw fixedly connected to the output end of the motor, a moving block threaded onto the outer surface of the lead screw, and a positioning plate fixedly connected to the bottom of the moving block. In this invention, the positioning rod, motor, positioning plate, pressure sensor, protective plate, lead screw, moving block, and scale work together to easily adjust the position of the positioning plate on the support frame according to the cutting length of the aluminum material. This allows the aluminum material to be positioned during cutting, ensuring the same cutting length each time, guaranteeing the production quality of the aluminum material, and improving production efficiency.

[0004] The aforementioned patent employs immersion cooling, a single cooling method. While immersion cooling provides extremely high cooling intensity to meet the quenching requirements of the alloys, its drawbacks are equally significant. The intense heat exchange generated when water comes into contact with high-temperature aluminum can cause enormous thermal shock to the profiles, especially thin-walled or asymmetrical profiles. This shock generates uneven structural and thermal stresses within the material, easily leading to uncontrollable permanent deformations (such as waviness and warping). In severe cases, it can even cause surface water spots, internal cracks, and other problems, seriously affecting the dimensional accuracy, surface quality, and consistency of internal quality, resulting in low yield.

[0005] Therefore, an aluminum extrusion press was proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned shortcomings by providing an aluminum extrusion machine.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: an aluminum extrusion press, comprising a main body, the main body including an extrusion box, a cooling box and a support base, the extrusion box and the cooling box being installed on the top of the support base, an extrusion nozzle being installed at one end of the extrusion box, the cooling box being installed on the side of the extrusion box where the extrusion nozzle is installed, an air-mist mixing cooling device being installed inside the cooling box, the air-mist mixing cooling device including an air supply module and an atomizing spray module, a small fan and an air outlet valve being installed inside the air supply module, the air outlet valve being installed at the bottom end of the small fan, a water storage tank being fixedly installed at the bottom end of the support base, a multi-stage centrifugal water pump being installed at one end of the water storage tank, the multi-stage centrifugal water pump and the air-mist mixing cooling device being connected by a pipeline.

[0008] In an optional implementation, the atomizing spray module includes multiple atomizing nozzles, the air supply module and the atomizing spray module are integrated on the same cross-section inside the cooling box, and the air outlet valve is alternately arranged with the atomizing nozzles.

[0009] In an alternative embodiment, the atomizing nozzles are arranged in a ring array on the cross-section of the cooling box.

[0010] In an optional implementation, a collection hopper is also provided at the bottom of the cooling box, the collection hopper being located below the air-mist mixing cooling device, and a drain outlet is provided at the bottom of the collection hopper. The drain outlet is connected to the water storage tank through a return pipe, and a filter is connected in series on the return pipe.

[0011] In an optional implementation, infrared thermometers are also provided on the inlet and outlet sidewalls of the cooling box. The aluminum extrusion press also includes a central controller. The data output terminal of the infrared thermometer is electrically connected to the central controller. The signal output terminal of the central controller is electrically connected to the frequency converter of the small fan, the electric regulating valve of the air outlet, and the frequency converter of the multi-stage centrifugal water pump, respectively.

[0012] The beneficial effects of this utility model are reflected in: This invention achieves an optimal balance between cooling intensity and uniformity through the synergistic effect of air cooling and mist cooling, thereby significantly improving product quality. Specifically, this air-mist hybrid cooling solution effectively overcomes the industry problems of insufficient single air cooling capacity and deformation caused by single water cooling. It utilizes airflow to accelerate water mist evaporation and disperse the surface water film, ensuring uniform heat dissipation of the aluminum material circumferentially and longitudinally. This directly results in a denser and more uniform metallographic structure of the extruded aluminum material, stable and compliant mechanical properties, and a significant reduction in deformation defects such as bending and twisting. The finished product exhibits high straightness, and the overall quality is fundamentally improved. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figure 1-3 This utility model discloses an aluminum extrusion press, including an extrusion box 2, a cooling box 4, and a support base 3. The extrusion box 2 and the cooling box 4 are both firmly mounted on the top of the support base 3, forming a stable whole. One end of the extrusion box 2 is provided with an extrusion nozzle 201 for forming and extruding aluminum material. The cooling box 4 is fixedly connected to the end of the extrusion box 2 with the extrusion nozzle 201. Its position is precisely designed to ensure that the high-temperature aluminum material just extruded from the extrusion nozzle 201 can be immediately and smoothly fed into the cooling box 4 for quenching treatment, achieving a seamless connection between the extrusion and cooling processes.

[0017] A water storage tank 301 is fixedly installed at the bottom of the support base 3 to provide cooling medium for the cooling box 4.

[0018] The air supply module is equipped with a small fan 401 and an air outlet valve. The small fan 401 provides a stable cooling airflow, which is sent out through the air outlet valve. The orientation of the air outlet valve is specially designed so that its airflow direction is directly facing the internal center of the cooling box 4, that is, the path through which the aluminum material passes.

[0019] The atomizing spray module includes multiple atomizing nozzles 403, and the spray direction of these atomizing nozzles 403 is also precisely aligned with the internal center of the cooling box 4. In order to achieve efficient supply of cooling medium, the water storage tank 301 is connected to the inlet of a multi-stage centrifugal water pump 302 through a water supply pipeline. The multi-stage centrifugal water pump 302 can generate a stable high-pressure water flow, and its outlet is connected to all the atomizing nozzles 403 of the atomizing spray module through the aforementioned water supply pipeline, providing them with a continuous high-pressure water source.

[0020] Furthermore, the air supply module and the atomizing spray module are highly integrated and arranged on the same cross-section inside the cooling box 4. Specifically, the air outlet and the atomizing nozzle 403 are arranged in an alternating manner, thereby forming a mixed cooling ring of air and water mist that surrounds the aluminum material in space.

[0021] Furthermore, the atomizing nozzles 403 can be evenly arranged in a ring array on the entire cross-section of the cooling box 4, ensuring that regardless of the cross-sectional shape of the aluminum material, each surface can be evenly covered by the cooling medium, effectively avoiding cooling dead zones, thereby ensuring the uniformity of the profile performance.

[0022] Furthermore, to achieve energy conservation, environmental protection, and media recycling, a collection hopper 405 is installed at the bottom of the cooling tank 4. This collection hopper 405 is located directly below the air-mist mixing cooling device and is used to efficiently collect coolant that drips due to failure to evaporate in time. The bottom of the collection hopper 405 has a drain outlet, which is connected to the water storage tank 301 via a return pipe, forming a complete coolant return channel. To ensure the cleanliness of the returned coolant and prevent nozzle clogging, a filter is connected in series in the return pipe to remove impurities from the liquid.

[0023] Furthermore, high-precision infrared thermometers 404 are installed on the inlet and outlet side walls of the cooling box 4, respectively. These infrared thermometers 404 can monitor the temperature changes of the aluminum material before and after cooling in a non-contact, real-time manner.

[0024] The command center of the entire system is a central controller. The data output terminals of the two infrared thermometers 404 are electrically connected to this central controller, providing it with decision-making information. The signal output terminals of the central controller are electrically connected to the frequency converters of the small fan 401 in the air supply module, the electric regulating valve at the air outlet, and the frequency converter of the multi-stage centrifugal water pump 302, respectively.

[0025] Workflow: In actual operation, high-temperature aluminum material is continuously extruded from the extrusion nozzle 201 of the extrusion box 2 and immediately enters the cooling box 4. First, the initial temperature is detected by the infrared thermometer 404 at the inlet. Subsequently, the aluminum material passes through a mixed cooling field created by the air-mist mixed cooling device, undergoing powerful and uniform quenching. During this process, the central controller intelligently adjusts the airflow and mist ratio based on real-time temperature feedback. The cooled aluminum material is then detected again by the infrared thermometer 404 at the outlet to ensure that its final temperature meets the standard. Unevaporated coolant is recovered by the collection hopper 405, filtered, and returned to the water storage tank 301 for recycling. Finally, the quenched aluminum material is sent to subsequent processes such as straightening and length setting.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
