Description

Technical Field

[0001] This utility model relates to the field of profile quenching, specifically to an online quenching device for magnesium alloy profiles. Background Technology

[0002] Magnesium alloys have gained significant attention in the automotive, electronics, and other mobile industries due to their lightweight, shock absorption, and electromagnetic shielding advantages. The use of high-performance lightweight alloys can further enhance weight reduction in components; therefore, manufacturers of related equipment and components are increasingly demanding higher performance from lightweight alloys.

[0003] Currently, the large-scale application of magnesium alloys is mainly concentrated in castings, profiles, and plates. Magnesium alloys can significantly improve the mechanical properties of cast alloys through deformation processes such as extrusion. However, during the extrusion process of magnesium alloys, due to their poor room-temperature plastic deformation plasticity, profiles often need to be formed at high temperatures. However, high-temperature forming of magnesium alloys generates further heat due to plastic deformation, and the atomic diffusion rate of magnesium alloys is relatively fast at high temperatures, often resulting in recrystallized grain growth, which in turn reduces the mechanical properties of the alloy. Online cooling of the extruded profiles can effectively solve these problems. This maintains a large number of substructures and fine recrystallized grains in the matrix, and also improves the age-hardening effect of the extruded profiles.

[0004] Conventional online quenching equipment for magnesium alloys typically uses mist cooling for both cooling and quenching. However, mist cooling is not fast enough, resulting in mechanical properties that do not meet customer requirements. If the heated magnesium alloy is placed directly in cooling water or oil, the rapid cooling rate of the water can easily cause the magnesium alloy to bend and result in uneven heating. This leads to deformation or cracking of the aluminum profiles due to inadequate cooling, compromising the quenching quality and yield, and ultimately hindering the efficiency and practicality of the quenching equipment.

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0025] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] An online quenching device for magnesium alloy profiles includes a main housing 1, a circulating water pump 2, and housing support legs 11. The main housing 1 has two openings on two corresponding sides for the profile 5 to enter and exit. The bottom of the main housing 1 has a water outlet, which is connected to the circulating water pump 2 by a water inlet pipe 12. The middle of the main housing 1 has multiple annular spray components 3, and multiple nozzles 31 are distributed on the annular spray components 3 to spray liquid onto the surface of the profile 5. The circulating water pump 2 is fixed to the housing support legs 11. The water outlet of the circulating water pump 2 is connected to a water outlet pipe 21. The top end of the water outlet pipe 21 is connected to a branch pipe 22, which is fixed to the side of the main housing 1 and is connected to the annular spray components 3. Both ends of the main housing 1 are provided with baffle plates 13, and a liquid storage tank is formed between the two baffle plates 13. Each annular spray component 3 is provided with a plug groove 14 on both sides. The plug groove 14 is slidably connected to the baffle plate 13. During use, the position of the baffle plate 13 can be adjusted according to the cooling length requirements.

[0027] In quenching, the cooling rate is a key indicator, which is related to both the length of the liquid storage tank and the flow rate of the coolant. The above settings allow for precise adjustment of the cooling length by changing the length of the liquid storage tank, and fine-tuning of the cooling rate by adjusting the flow rate of the nozzle 31.

[0028] The main housing 1 provides a channel for the profile 5 to enter and exit, and achieves uniform spray cooling of the profile 5 through the annular spray assembly 3 and nozzles 31, ensuring a stable and uniform cooling rate, thereby improving the mechanical properties of the magnesium alloy profile. The circulation water pump 2 and the outlet pipe 21 ensure the circulation of coolant, improving the efficiency of the device. The design of the baffle plate 13 and the liquid storage tank prevents coolant splashing, avoiding any impact on the unquenched profile 5.

[0029] In some embodiments, each annular spray assembly 3 is connected to a flow regulating valve 32. The flow regulating valve 32 can adjust the flow rate of the sprayed liquid, thereby controlling the cooling rate. By precisely adjusting the cooling rate, it can be ensured that the magnesium alloy profile will not deform due to excessive cooling or have its mechanical properties affected by insufficient cooling during the quenching process. Furthermore, the flow regulating valve 32 can be adjusted by a manual or automatic control system to adapt to different quenching requirements. Even further, the flow regulating valve 32 can employ an electric or pneumatic actuator to achieve more precise and rapid flow control.

[0030] In some embodiments, the annular spray assembly 3 is fixed inside the main housing 1 by a bracket and is uniformly arranged along the direction of movement of the profile 5. By uniformly arranging the annular spray assembly 3, the cooling rate can be effectively controlled, allowing the matrix to retain a large number of substructures and fine recrystallized grains, thereby improving the age-hardening effect of the extruded profile 5 and enhancing the mechanical properties of the magnesium alloy profile. Specifically, this design avoids deformation or cracking of the profile 5 due to uneven cooling, ensuring the uniformity and consistency of the cooling process, thereby improving the overall quality and mechanical properties of the magnesium alloy profile.

[0031] In some embodiments, the height of the baffle plate 13 is higher than the side height of the main housing 1, and it has through holes for the profile 5 to pass through.

[0032] In some embodiments, a sealing rubber is provided inside the insertion groove 14. The sealing rubber is provided to enhance the sealing performance between the water-blocking plate 13 and the insertion groove 14, preventing liquid leakage during the quenching process. The sealing rubber can be made of a highly elastic material to ensure good sealing performance under different temperature and pressure conditions.

[0033] In some embodiments, a heating tube 4 is installed at the bottom of the liquid storage tank. The heating tube 4 is arranged and fixed at the bottom of the vertical side. It can be electrically heated. For Mg-RE-Zr alloys that are highly sensitive to cooling rate, hot water is often used for quenching to maintain the original elongation.

[0034] In some embodiments, the end of the housing support leg 11 away from the main housing 1 is provided with a swingable caster 111. The swingable caster 111 on the housing support leg 11 provides mobility for the device, allowing it to be easily moved to different working positions. At the same time, the swingable design of the caster 111 ensures the stability of the device during movement, preventing tilting or instability caused by movement, thereby improving the practicality and ease of operation of the device.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
