Abstract

The invention discloses a metal extruding, casting and forging forming method and products of the method, and particularly relates to the extruding, casting and forging forming method of light alloy or light alloy composite materials in the same die, and the products of the method. The extrusion casting technology and the continuous casting and continuous forging technology are improved, and the method mainly solves the problem that the plastic deformation of the continuous-casting and continuous-forging critical deformation. According to the technical scheme, an unfilled cavity is reserved at the casting stage, the volume of the cavity needs to be larger than the size corresponding to the workpiece forging critical deformation, and then at the forging stage, through plunger extrusion, the cavity is fully filled in the plastic deformation process or grain refinement filling process. The method is a novel metal hot working forming method, casting, forging and semi-solid state processing are integrated, and the method is suitable for manufacturing high-performance force bearing parts and airtight parts like aluminum wheels and connecting rods.

Description

technical field [0001] The invention relates to a forming method of metal or metal-based composite material and its products, especially a forming method and its products in which light alloy or light alloy composite material is cast and forged in the same set of moulds. Background technique [0002] Both squeeze casting and die forging belong to the existing metal hot working forming methods. Squeeze casting is to fill the mold cavity with liquid metal material under the action of gravity or mechanical force, and then make the molten metal crystallize and solidify under higher pressure. The disadvantage is that although the extrusion specific pressure is higher than other casting methods, it still cannot cause obvious plastic deformation of the workpiece. [0003] Die forging is to heat the solid metal billet, and then put it into the forging die. After the forging press is pressurized, the solid metal billet is plastically deformed to fill the forging die cavity. Die for...
