Casting forming equipment and process for amorphous alloy component

Abstract

Provided is a device for the casting forming of amorphous alloy components. The device comprises an injection system, an alloy smelting system, a raw material feeding system, a mould system, a vacuum system and a protective atmosphere system, which are used for the preparation of the amorphous alloy components, and can realize the formation by squeezing casting of the amorphous alloy components under a vacuum or a protective atmosphere with a positive pressure. The device is provided with an exhaust port on the mould to effectively solve the problem of forming micro shrinkage cavities on the surface in the process of forming the alloy components so as to improve the quality of the amorphous alloy components. Also provided is a process for the casting forming of the amorphous alloy components. A high vacuum tank or a protective atmosphere tank is used to reach an acquisition time of the vacuum or protective atmosphere with a positive pressure so as to shorten the forming period, save the production cost, and improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of amorphous alloy forming, in particular to an amorphous alloy component casting forming equipment and process. Background technique [0002] Due to its unique long-range disordered and short-range ordered atomic arrangement structure, bulk amorphous alloys exhibit a series of excellent physical, chemical and mechanical properties, such as high strength, high elasticity, high fracture toughness, high specific strength, Superplasticity, high corrosion resistance, outstanding magnetic properties, excellent formability, etc., are more and more widely used in aviation, aerospace and civil fields. At present, the most successful performance of amorphous alloy application is its outstanding soft magnetic properties, which has made amazing progress and great benefits. Small motors and transformers using amorphous alloys as magnetic components have achieved initial commercial success. The high elasticity of Zr-ba...

Problems solved by technology

In casting technology, when all the actions of each molding are completed, to realize the feeding of raw materials, the vacuum of the main chamber must be broken, or a large amount of gas will be wasted, which will lead to the failure of each working cycle of the amorphous alloy workpiece. Lengthening and reduction in productivity

In addition, in order to realize the molding under vacuum conditions, the mold adds a sealing ring, which leads to no vent holes around the mold cavity during the filling process, making it easy to form air holes or shrinkage cavities on the surface of the amorphous alloy component

In addition, in the reported technologies, the vacuum chamber or protective atmosphere chamber needs to be evacuated for a period of time, or filled with gas with a certain pressure, which leads to a decrease in the forming efficiency of amorphous alloy components.
