Large-table gravity casting machine

    For the high-altitude, high-speed operating environment of aircraft, customized forgings must possess excellent mechanical properties: ① Fuselage frame beams: Custom-forged "large-size irregular beams" (up to 5m in length, 300×200mm in cross-section), made of 2024-T351 aluminum alloy (tensile strength ≥470MPa, fracture toughness ≥45MPa・m¹/²), using a "die forging + tensile straightening" process, with a straightness error ≤0.5mm/m, ensuring the stability of the fuselage structure; ② Wing joints: Custom-made "multi-directional forged joints" to achieve "one-forging," replacing the traditional split welded structure, increasing fatigue life to 10⁷ cycles without cracks, adapting to the vibration and impact of frequent takeoffs and landings; ③ Landing gear components: Custom-made "high-strength forged piston rods" according to the aircraft's load (e.g., 10 tons, 20 tons), made of 7050-T7451 aluminum alloy. Aluminum alloy (tensile strength ≥510MPa, yield strength ≥455MPa), with hard…
