Preparation device and shaping method of ultrafine grain and nanograin blanks

Abstract

The invention discloses a preparation device and a shaping method of ultrafine grain and nanograin blanks. The preparation device comprises a rotary extrusion sleeve, a main shaft and an auxiliary shaft, wherein the rotary extrusion sleeve is installed on the main shaft, and equipped with a front sealed cap loading and unloading hydraulic device and a rear sealed cap loading and unloading hydraulic device, the rotary extrusion sleeve comprises a main shaft sleeve wheel, a main shaft sleeve wheel external gear and a main shaft sleeve wheel cooling system, extrusion dies are installed on the front sealed cap loading and unloading hydraulic device and the rear sealed cap loading and unloading hydraulic device, the main shaft is equipped with a main shaft cooling system, and rotated through amotor, the auxiliary shaft is driven by the motor, equipped with a key groove, and connected with an auxiliary shaft sleeve wheel through a flat key, and the auxiliary shaft sleeve wheel is equipped with an auxiliary shaft sleeve wheel external gear. The preparation device of the ultrafine grain and nanograin blanks can simultaneously produce the ultrafine grain and nanograin blanks, and bars, pipes, wires, filaments, profiled bars and the like of the ultrafine grain and nanograin blanks, is low in energy consumption, reduces production cost, and can be used in efficient production of materials of liquid, and semisolid, solid, powder and the like which have a certain solid fraction.

Description

Technical field [0001] The invention relates to the technical field of short-flow processing of metal materials, and more specifically to a preparation device and a forming method of ultrafine crystal and nanocrystal blanks. Background technique [0002] Existing equipment for the production of tubes, rods, wires, and profiles has the advantages of energy saving, high yield, short process, etc., but the produced products have coarser grains, poor performance, and single production. Tubes, rods, and rods cannot be produced at the same time. A variety of products such as threads and profiles cannot be used in the production of liquid, semi-solid, solid, powder and other materials with a certain solid phase rate at the same time, which severely limits the diversification of production products and increases production costs. Summary of the invention [0003] The embodiment of the present invention provides a preparation device and a forming method of ultra-fine crystal and nanocrysta...
