Light-alloy die-casting, filling, forging and compacting integrated forming device and forming method

Abstract

The invention provides a forming device and a forming method, particularly relating to a light-alloy die-casting, filling, forging and compacting integrated forming device and a forming method. The invention aims at solving the problem that the existing device for die-casting forming and forging forming can not form the parts that comply with the standard, and have complex shapes and high mechanics performance requirements. The forming device comprises the following components that are sequentially connected with: a movable die bottom plate, a movable die cushion plate, a movable die plate, amiddle plate and a fixed die plate; a concave die is embedded in the middle plate; a convex die is inserted in the movable die plate; the working end surface of the convex die and the working end surface of the concave die form a die cavity; the forging component sequentially passes through the movable die bottom plate and the movable die cushion plate and is connected with the rear end of the convex die. The forming method comprises the following steps of melting the light-alloy casting-state billets into a liquid state and injecting the liquid-state light-alloy billets into the die cavity; and forging the parts filling the die cavity by adopting the forging component. The forming device and the forming method are used for forming the light-alloy parts with complex shapes and high mechanics performance requirements.

Description

technical field [0001] The invention relates to a forming device and a forming method, in particular to a light alloy die-casting filling forging compact integrated forming device and a forming method. Background technique [0002] The lightness of products is actually to use the low density of aluminum alloys and magnesium alloys to replace traditional materials. At present, aluminum alloys and magnesium alloys are mainly manufactured by casting or forging. Die-casting forming is to fill the mold cavity by pushing the liquid metal flow through the piston. Although the die-casting forming can realize the precise control of the shape of the part, it is difficult to control the performance of the part, and defects such as air holes, shrinkage cavities and shrinkage porosity often occur; Forging forming relies on the plastic deformation of solid metal to fill the die cavity. Although forging forming is easy to control the performance of the part, the shape of the part is greatl...
