Embodiment

[0038] An amorphous alloy circular tube extrusion forming device, comprising a hydraulic extrusion structure 1, an extrusion die, and an extrusion tooling frame 11, and the extrusion die includes an extrusion punch 2, an extrusion barrel 4, and an extrusion die 6. The shaping sleeve 9, the extrusion cylinder 4, the extrusion die 6, and the shaping sleeve 9 are sequentially connected and fixed together. The cavity formed in the extrusion die has four parts: a blank chamber, a shunting chamber, a welding chamber and a forming chamber. The extrusion die 6 is designed as a block structure, and the joint line of each block is selected at the welding chamber. The extrusion die 6 is covered with an extrusion die clamping sleeve 10, and the outer extrusion die The surface is combined with the inner surface of the extrusion die clamping sleeve 10 in the form of a progressive tapered surface, and the extrusion die clamping sleeve 10 is fixed on the extrusion tooling frame 11 .

Abstract

The invention relates to an amorphous alloy round pipe extrusion forming device and technology. The device comprises a hydraulic type extrusion structure, an extrusion die and an extrusion tool frame, the extrusion die comprises an extrusion male die, an extrusion cylinder, an extrusion female die and a setting sleeve, the extrusion cylinder, the extrusion female die and the setting sleeve are sequentially and fixedly connected together, a cavity formed in the extrusion mould comprises a blank chamber, a flow dividing chamber, a welding-on chamber and a forming chamber, the extrusion female die is designed to be of a splicing block structure, a splicing line of each splicing block is selectively arranged at the position of the welding-on chamber, the extrusion female die is a cylindrical die body, a mold core is formed on the axis of the die body, the extrusion female die is sleeved with an extrusion female die clamping sleeve, the outer surface of the extrusion female die and the inner surface of the extrusion female die clamping sleeve are combined in a gradually-advancing type conical-face mode, and the extrusion female die clamping sleeve is fixed to the extrusion tool frame. The extrusion forming device is convenient to dismount and mount, and reasonable in structure, the size precision of a formed round pipe is high, the surface quality is good, extrusion wastes are easy to clear, and the production efficiency is high.

Description

technical field [0001] The invention relates to an extrusion forming process and device for an amorphous metal glass circular tube, and belongs to the technical field of amorphous metal 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 cooling rate, and a com...
