Abstract

The invention discloses a device and method for antigravity forming of titanium and titanium alloy complex thin section castings and relates to a casting antigravity forming device and method. The device and method aim to solve the problems that an existing forming device can not achieve smelting in a high-inertia environment, lifting and sealing of a riser tube and waste liquid processing. The device comprises an upper tank, a middle partition section, a lower tank, a hydraulic ejector rod, a power supply, a tilting-type heating coil, a crucible, a vacuum system, a liquid level adjusting system, a circulating water cooling system, a smelting observation mechanism, a smashing mechanism, a feeding mechanism, a temperature measuring mechanism, a riser tube, a fluid power system, a casting mold lifting system, a casting mold and a standby casting mold. The casting mold lifting system is arranged in the upper tank. The tilting-type heating coil, the crucible and the standby casting mold are arranged in the lower tank. The method comprises the steps that metal is fed into the crucible, the lifting system rises, vacuum pumping is conducted, and argon is injected; after the metal is molten, the lifting system is lowered to press the casting mold; argon is injected to the lower tank, and a casting is formed; the casting is cooled and taken out. The device and method are used for preparation of the titanium and titanium alloy complex thin section castings.

Description

technical field [0001] The invention relates to a casting anti-gravity forming device and a forming method. Background technique [0002] Titanium and titanium alloy complex thin-walled castings are widely used in aviation, aerospace, medical equipment, automobiles and other fields. Ordinary gravity casting or centrifugal casting has been difficult to meet the development needs of forming technology, especially titanium and titanium alloys have high melting points, and the chemical activity is very high in the molten state, which can almost react with the existing engineering materials, so its melting And forming is extremely difficult, especially when forming complex thin-walled castings of titanium and titanium alloys, which puts forward higher requirements for its forming device and forming process. At present, the smelting methods of titanium and titanium alloys used in industry are mainly vacuum consumable electrode shell smelting and vacuum non-consumable electrode co...
