Problems solved by technology

Since the continuous completion between the previous pass and the next pass has not been achieved so far, the processing cost is relatively high; moreover, at present, only small-sized block materials can be processed, and industrialized large-scale production cannot be carried out.

Abstract

The invention discloses a tee corner extruding automatic continuous processing equipment and a processing method thereof, relating to the field of material processing, particularly relating to a tee corner extruding equipment which can automatically and continuously process and produce superfine crystals or nanocrystalline metal-base materials and a method thereof. The invention includes a mould, a first punch, a second punch, a third punch and a feeding and discharging opening. Tee corner extruding cavities are arranged in three neighboring directions in the mould, the first punch, the second bunch and the third punch are arranged in the three cavities respectively; the feeding and discharging opening is arranged in the direction of the other side; the cross-section size of the feeding and discharging opening is larger than the first punch, the second punch and the third punch; the first punch, the second punch and the third punch are connected with a hydraulic control system respectively. The invention is simple in structure, easy to be operated and has an extensive application scope.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a T-shaped corner extrusion device and method capable of automatic and continuous processing to produce ultra-fine crystal or nanocrystalline metal-based materials. Background technique [0002] Equal channel angular extrusion (ECAP) was developed in the 1980s by Russian scientist Professor Segal and his colleagues on the basis of studying pure shear deformation. Its original purpose is to produce severe plastic deformation without changing the cross-section of the material, so that repeated deformation of the material is possible. [0003] Compared with the ordinary deformation method, the microstructure, structure and performance of the processed materials are very different. Common deformation processing methods such as low-temperature cold rolling and cold drawing can cause work hardening of the material and increase its strength, but its microstructure usually has a subst...
