Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy manufacturing, in particular to an aluminum alloy extrusion quenching device. Background Art

[0002] In-line quenching is a crucial step in the aluminum extrusion process. It involves heating the aluminum profile above its phase transition temperature, holding it for a certain period of time, and then rapidly cooling it to a lower temperature, typically room temperature, to form a saturated solid solution, thus allowing for heat treatment. The cooling rate during quenching directly affects the quenching intensity, which in turn determines product performance. In theory, faster cooling rates result in higher quenching intensity and, consequently, better product performance. However, high-intensity quenching often causes deformation during the rapid cooling process, making it extremely difficult to maintain precise dimensional tolerances. To ensure both high performance and high precision, a quenching device is needed that can achieve high-intensity quenching while controlling deformation during cooling. However, current water troughs used in in-line quenching have several significant drawbacks that limit their potential for precise control. First, existing water trough designs typically lack the ability to adjust the nozzle spray angle. This means that the cooling water spray direction cannot be precisely controlled to suit the shape and size of the profile, impacting both the uniformity of the cooling effect and the cooling rate of the profile. Secondly, the adjustment of the water flow size is also a problem. In the existing water trough design, the water flow size is often fixed and cannot be adjusted according to the specific needs of the profile. This results in the profile being overcooled due to excessive water flow or insufficiently cooled due to too little water flow during the quenching process. Both of these situations may cause the dimensional tolerance of the profile to exceed expectations, affecting the final quality of the product. In summary, the shortcomings of the existing water trough quenching system in terms of spray angle and water flow size adjustment limit its application effect in the aluminum profile extrusion process. In order to achieve more efficient and more precise quenching operations, it is necessary to develop a new generation of quenching devices to overcome the limitations of existing technologies and meet the needs of modern industry for high-performance and high-precision aluminum profiles. In response to the above-mentioned problems, it is very necessary to study and design a new type of aluminum alloy extrusion quenching device to overcome the problems existing in the existing aluminum alloy profile quenching.

The water tank body 1 is a U-shaped trough for placing profiles. There are two sealing water baffles 2, which are respectively arranged at the front and rear ends of the water tank body 1. During quenching, in order to prevent the water in the quenching device from entering the extrusion equipment and the mold in the reverse extrusion direction and affecting the quenching effect, the water in the water tank is isolated from the unquenched area by setting a sealing water baffle 2. There are multiple water supply pipes 6, and multiple water supply pipes 6 are respectively arranged on the inner side of the side wall of the water tank body 1. There are multiple spray water pipes 4, and multiple spray water pipes 4 are respectively connected to the water supply pipe 6, and each spray water pipe 4 is arranged on the inner side of the side wall of the water tank body 1. There are multiple water nozzles 8, and multiple water nozzles 8 are respectively arranged on the spray water pipe 4 for spraying water to the profile. After the water used for cooling enters the device through the water supply pipe 6, it flows to the spray water pipe 4 and is finally sprayed out through the water nozzle 8.

[0028] It should be noted that, as a preferred embodiment of the present invention, the inner surfaces of the left and right side walls and the upper surface of the bottom plate of the water tank body 1 at both ends are provided with baffle sealing grooves 3, and the sealing water baffle 2 is connected to the water tank body 1 through the baffle sealing grooves 3. As a preferred embodiment of the present invention, Figure 2 As shown, two baffle sealing grooves 3 can be set at the front and rear ends of the sink body 1, and the two baffle sealing grooves 3 are arranged in parallel. A sealing water baffle 2 is provided in each of the four baffle sealing grooves 3. By arranging two layers of sealing water baffles 2 at the front and rear ends of the sink body 1, it is possible to more effectively prevent water inside the sink body 1 from flowing out of the sink body 1.

[0029] It should be noted that, as a preferred embodiment of the present invention, Figure 1-3As shown, the water supply pipe 6 is connected to the spray water pipe 4 through a rotating joint 7. The spray water pipe 4 is parallel to the bottom plate of the water tank body 1. By setting the rotating joint 7, the spray water pipe 4 can be rotated in the rotating joint 7, thereby driving the water nozzle 8 on the spray water pipe 4 to swing up and down, adjusting the angle of the water nozzle 8 to spray water to the profile, optimizing the cooling area of ​​the profile during online quenching, and adjusting the quenching intensity of the deformation zone of the profile. As a preference of this embodiment, four water supply pipes 6 can be provided, and four spray water pipes 4 can be provided. The spray water pipes 4 are connected to the water supply pipes 6 one by one. More preferably, the connected spray water pipes 4 and water supply pipes 6 are arranged perpendicular to each other, and each spray water pipe 4 is provided with sixteen water nozzles 8. The sixteen water nozzles 8 are arranged at intervals on the spray water pipe 4.

The spray water pipe 4 can be connected to the side wall of the water tank body 1 through a fixed bracket 5. By setting the fixed bracket 5, the connection between the spray water pipe 4 and the water tank body 1 can be made more stable.

[0030] It should be noted that, as a preferred embodiment of the present invention, Figure 4 As shown, the water supply pipe 6 is connected to the main pipe 10 through the water divider 9. After the water flows into the main pipe 10, it is divided into multiple paths through the water divider 9. The multiple water flows flow into the water supply pipe 6 respectively. A pressure gauge 11 can be provided on the main pipe 10. By setting the pressure gauge 11, the pressure of the water flow can be monitored in real time to ensure the water supply pressure of the entire quenching device. A valve 12 is provided at the connection between the water divider 9 and the water supply pipe 6. The water divider 9 controls the flow rate of water in the water supply pipe 6 through the valve 12 to adjust the water flow size and change the quenching intensity of the deformation position of the profile in a targeted manner through the water flow size.

[0031] This quenching device transforms the existing water tank into an online quenching system with four spray pipes 4 and sixty-four water nozzles 8. The water jet angle can be adjusted during operation, solving the problem of deformation caused by rapid cooling from high temperature to low temperature during online quenching, which cannot be adjusted. The quenching device of this utility model can specifically change the quenching intensity at the deformed position of the profile, and monitor and intervene in the quenching deformation process in real time. Compared with the quenching device before the transformation, it greatly improves the product dimensional qualification rate and significantly reduces production costs.
