Die casting mold for aluminum alloy forming

PendingCN122274122Aprevent getting involvedReduce initial gas contentDie castingCasting mold
This invention relates to the field of die-casting mold technology and discloses a die-casting mold for aluminum alloy forming, comprising a moving mold and a fixed mold, and further comprising: a pre-vacuuming mechanism, fixedly installed inside the fixed mold, the pre-vacuuming mechanism including a sealing element and a pre-vacuuming channel communicating with the sealing element, and a slot corresponding to the sealing element on the moving mold; a vacuuming mechanism, including a fixed mold vacuuming component fixed on the fixed mold and a moving mold vacuuming component fixed on the moving mold; and a feeding assembly, fixedly installed on the side of the fixed mold away from the moving mold. This die-casting mold for aluminum alloy forming, by setting the pre-vacuuming mechanism and the vacuuming mechanism, initiates pre-vacuuming during the mold closing process, utilizing the dynamic stage of the gradually decreasing cavity volume to expel most of the gas in advance; a second vacuuming is performed after mold closing to further extract residual gas. The synergistic effect of the two vacuuming processes effectively reduces the initial gas content in the cavity.

Air-liquid separation tank for compressed air

The gas-liquid separator for compressed air provided by this utility model includes a tank body, an exhaust pipe, and a swirl vane device. The tank body includes a cylindrical tank body, an elliptical end cap connected to the top of the tank body, and a sealing plate connected to the bottom of the tank body. The tank body is provided with an air inlet and an exhaust outlet. The exhaust pipe is located inside the tank body, with its upper end connected to the exhaust outlet and its lower end extending downward and coaxial with the tank body to form a straight pipe section. The swirl vane device is sleeved on the upper end of the straight pipe section and is lower than the air inlet. By sleeved with an elliptical guide shroud on the straight pipe section, which is located below the swirl vane device and higher than the lower end of the straight pipe section, and a cooling coil for cooling is set between the elliptical guide shroud and the straight pipe section, the inlet and outlet ends of the cooling coil penetrate the tank body and extend outward. This not only utilizes the guiding effect of the elliptical guide shroud to prevent liquid water from being re-entrained into the exhaust pipe by the airflow, but also enables water vapor condensation through the cooling coil, thereby improving the gas-liquid separation rate and reducing the temperature of the compressed air, making it suitable for subsequent use.

A short process manufacturing technique for high performance titanium-aluminum alloys

This invention provides a short-process manufacturing technology for high-performance titanium-aluminum alloys, relating to the technical field of titanium-aluminum alloy material preparation. The manufacturing technology uses hydrogenated dehydrogenated powder, aluminum-vanadium alloy, and aluminum-niobium alloy as raw materials. Through hydrogenated dehydrogenation powder preparation, cold isostatic pressing, vacuum sintering, and subsequent processing, a uniformly composed titanium-aluminum alloy is prepared. Utilizing the intrinsic brittleness of titanium-aluminum after its self-propagating reaction, and combining the high purity and easily breakable characteristics of aluminum-vanadium and aluminum-niobium master alloys, the technology achieves thorough mixing and refinement of multiple elements under solid-state conditions. This avoids the microstructure inhomogeneity caused by diffusion limitation in high-vanadium and high-niobium systems, and overcomes the problems of component segregation, coarse microstructure, and difficulty in removing inclusions associated with traditional casting methods for preparing titanium-aluminum alloys. Through the powder metallurgy short-process manufacturing design, this technology offers significant technical advantages in reducing raw material and manufacturing costs, improving compositional and microstructure uniformity, enhancing comprehensive mechanical properties, and achieving large-scale production.

Multi-degree-of-freedom guide plate adjusting device and method of thin-walled composite pipe three-roll rolling mill

This invention belongs to the field of thin-walled metal composite tube forming technology, specifically relating to a multi-degree-of-freedom guide plate adjustment device and method for a three-roll mill for thin-walled composite tubes. The multi-degree-of-freedom guide plate adjustment device includes a slide block, with a first slider and a second transmission block fixedly arranged on both sides of the slide block. The second transmission block is threadedly connected to a second lead screw, one end of which is fixedly connected to the output shaft of a drive motor. The drive motor is fixedly mounted on the inner wall of a first housing. A first groove corresponding to the first slider is formed on the inner wall of the first housing. Cylinders are arranged on both sides of the first housing, with the other end of each cylinder fixedly connected to a second housing. This invention enables radial, circumferential, and axial translational adjustment of the guide plate position, as well as rotational adjustment around a rotating platform, ensuring the guide plate can adhere to the rolls. For thin-walled composite tubes, this invention effectively solves the jamming phenomenon caused by metal being squeezed between the rolls and the guide plate.

A PLC-controlled co-process for static continuous casting and rolling of molten scrap aluminum

This application relates to the field of recycled aluminum processing technology and discloses a PLC-controlled co-process for continuous casting and rolling of molten waste aluminum. The process includes: after raw material smelting and homogenization, it is transferred to a holding furnace; a flux-impregnated porous ceramic plate and high-density flux are pre-placed at the slag neck at the bottom of the furnace; gradient sedimentation is achieved by establishing a vertical temperature gradient, utilizing the liquid flux within the plate to adsorb and settle impurities; before casting, the slag neck is forcibly cooled, causing the flux to undergo phase change and solidify to form a physical locking layer, preventing impurities from mixing back; during the continuous casting stage, the PLC system dynamically adjusts the opening of the flow channel plug based on a rheological model according to the viscosity change caused by the temperature decay of the molten aluminum, geometrically compensating for flow rate loss and maintaining a constant flow rate; finally, the aluminum is continuously rolled, quenched, and coiled. This invention achieves deep purification using a "gradient sedimentation-phase change locking" mechanism and eliminates product dimensional deviations caused by temperature fluctuations through a "viscosity compensation" mechanism, improving the quality stability of recycled aluminum rods.
