A forming device and forming method based on vacuum induction heating

Abstract

The invention provides a forming device based on vacuum induction heating. The forming device is technically characterized by comprising a device body, the device body comprises a vacuum chamber, a forging device and an induction coil are arranged in the vacuum chamber, a cooling device is arranged in the forging device, a prefabricated blank is arranged at the bottom of the forging device, a forming method based on vacuum induction heating, the extrusion and forging are combined together in a vacuum environment, metal raw materials are melted by adopting an induction hardening and shell smelting method and are laid according to the track, after molten drops paved on the prefabricated blank are solidified, the molten drops are subjected to thermal mechanical processing immediately, so thatthe hot mechanical processing is carried out. According to the forming device, the metal materials are extruded from an extrusion type forging head and has a good processing streamline, forging and machining are carried out, the metal materials are connected with the prefabricated blank through forging and welding, the interlayer metal is not fusion covering and is fixedly connected, so that metallurgical defects do not exist, the combination quality is good, the cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of forming metal parts, in particular to a forming device and a forming method based on vacuum induction heating. Background technique [0002] Additive manufacturing technology is mainly divided into two categories, one is powder bed additive manufacturing technology, including electron beam, laser beam selective cladding, powder bed method is generally used to form complex structures; the other is deposition additive manufacturing Technology, mainly including electric arc (argon arc or plasma arc) fuse free forming, electron beam and laser beam free forming of fuse, laser powder feeding direct deposition forming, metal droplet jet deposition technology, etc., are currently applicable to large-scale overall complex The method of structure is mainly deposition additive manufacturing technology, commonly used deposition methods mainly include laser (coaxial powder feeding, wire feeding) deposition technology,...

AI Technical Summary

Problems solved by technology

[0005] In summary, some existing additive manufacturing methods are used to manufacture large-size, complex and high-performance structural parts of aluminum alloys, aluminum-lithium alloys, titanium alloys, titanium-aluminum alloys, and niobium-silicon alloys. There are some deficiencies in material manufacturing technology: 1) The cost of raw materials is high, and the cost of powder and wire materials is relatively high, especially some high-performance powders and wire materials; 2) Some raw material wire materials are difficult to prepare, such as high-temperature titanium alloys (Ti6242, Ti60, etc.), titanium-aluminum alloy, titanium-di-aluminum-niobium alloy, etc.; 3) The parts obtained by deposition-based additive manufacturing methods are generally rapid solidification structures, which are prone to defects such as cracks, lack of fusion, and cracks. Compared with forged structures, Insufficient performance
