Device and process for coating wire rod by multi-directional extrusion of amorphous alloy

Abstract

The invention relates to a device and a process for cladding a wire rod with an amorphous alloy through multidirectional extrusion. An extrusion female die is divided into an upper splicing block and a lower splicing block which can be spliced to form a wire rod channel, an extrusion male die channel, a blank chamber, a welding chamber and a forming chamber; the wire rod channel and the extrusion male die channel are perpendicular to each other; the blank chamber and the extrusion male die channel are formed in a same line; the welding chamber, the forming chamber and the wire rod channel are formed in a same line; the blank chamber and the extrusion male die channel are formed at two sides of the wire rod channel, respectively; a protective gas spray pipe is arranged at an outlet of the wire rod channel; electrical heating elements are arranged in the extrusion female die. According to the invention, the amorphous alloy can coat the surface of the wire rod, and thus the surface quality of the wire rod is improved.

Description

technical field [0001] The invention relates to a device and process for continuous coating of wire rods by multi-directional extrusion, and belongs to the technical field of amorphous metal cladding and forming. Background technique [0002] Metallic glasses, also known as amorphous alloys, have the advantages of metals and glasses while overcoming their respective disadvantages due to their unique disordered microstructure. Glass is fragile and has no ductility; but metallic glass is stronger than steel, harder than high-hard tool steel, and has certain toughness and rigidity. Therefore, people call metallic glass "unbreakable and unbreakable". The King of Glass". Amorphous alloys have good mechanical, physical and chemical properties such as high strength, high hardness, good wear resistance and corrosion resistance, which determine their wide application fields and broad application prospects. [0003] Zirconium-based amorphous has lower requirements on the limit cooli...

AI Technical Summary

Problems solved by technology

[0005] When covering wire or rod with amorphous alloy, if the wire or rod is covered by unidirectional extrusion process, the shunt chamber, welding chamber and forming chamber must be designed in the extrusion die , the structure of the mold is complex, the processing cost is high, and the extrusion force required is large, and the life of the mold is low
