The present disclosure provides a device and a method for controllable forging of a forming flow line of a complex-shaped component. The device includes a frame, a shaping unit, a cushioning unit, and a cleaning unit, and the frame is used to mount and fix the shaping unit, the cushioning unit, and the cleaning unit; the shaping unit is used to improve a shaping capacity of processed parts; the cushioning unit is used to reduce a vibration in a metal shaping process to avoid an impact on the shaping of the metal; the cleaning unit is used to clean up a surface of a mold after shaping; when the metal is put into the mold, the metal is extruded and shaped through the shaping unit, and at the same time, the cushioning unit is used to offset the vibration generated by the shaping unit during the shaping process.

Devices and methods for controllable forging of forming flow line of complex-shaped component

The application provides a plaster casting mold fabrication method for a complicated structure aluminum alloy casting with a large inner cavity and a thin wall, in which, a wax pattern is cleaned with a mixture; closed blind cavity and large plane unbeneficial to plaster mold-filling of the wax pattern are used to exhaust air by using vent holes and waterproof-breathable membranes in cooperation with each other; under pressure difference, plaster powder and mixed aqueous solution are vertically splashed and mixed in a mixing tank to reduce dust discharge; asynchronous mixing and grouting can be realized by left and right mixing tanks in an upper tank of a vacuum tank. The present application can effectively remove the surface parting agent, increase the wettability of the plaster paste and the wax pattern surface, and improve the surface finish of the casting mold.

A method for vacuum smelting and variable pressure solidification forming aluminum alloy piece with ultra-thin wall and high gas tightness is provided, in which an induction heating furnace is set in a vacuum tank, a quartz crucible with thickness of 5&#x2dc;8 mm is used; a preheated aluminum alloy ingot is placed in the crucible, side doors of the tank is closed, and a vacuuming processing is performed for the tank; the melt is filled from the bottom layer of the casting; when the melt reaches to the top, the main valve and the air-release valve are turned on until the inside and outside pressures are consistent, and then the casting is taken out. The requirement of high air tightness for vacuum tank is reduced, and aluminum alloy casting with high quality can be obtained at lower cost.
