Abstract

The invention discloses a light alloy vacuum high-pressure casting flexible loading casting-forging composite forming device and an application method thereof, and relates to a light alloy vacuum casting-forging composite forming device and an application method thereof. The invention aims to solve the technical problem that casting defects at a thick wall are difficult to regulate and control in the current alloy vacuum die-casting technology. According to the device, a vacuum pump is used for pumping out gas in a cavity before aluminum alloy or magnesium alloy melt enters the cavity of a die, so that gas residues in the cavity are greatly reduced, the gas entrapment degree of a die casting is obviously lowered, and the effect of improving the mechanical properties and compactness of the die casting is obvious; and a flexible loading system which is composed of a flexible loading hydraulic cylinder, a flexible loading dowel bar, a flexible loading limiting plate and a flexible loading block and mounted on a movable die is adopted to conduct local loading and forced feeding on the liquid-solid aluminum alloy or magnesium alloy melt, so that the casting defects at the thick wall are obviously reduced, which is beneficial for improving the compactness and macroscopic mechanical properties of the casting.

Description

technical field [0001] The invention relates to a light alloy vacuum casting and forging composite forming device and its application method. Background technique [0002] Light alloy metal materials including aluminum alloys and magnesium alloys are widely used in the fields of aviation, aerospace, weapons, automobiles, rail transit and 3C due to their light weight, high specific strength and specific stiffness, energy saving and emission reduction. be widely used. The national demand for energy saving, emission reduction, efficiency increase and consumption reduction is constantly increasing, which is very urgent for the lightweight of equipment, and the simple replacement of traditional steel with aluminum alloy or magnesium alloy can not meet the requirements of equipment use. Combined with forming manufacturing methods to achieve real lightweight, this can meet the needs of equipment use and ensure the safety and efficiency of its operation. Die-casting technology is ...
