Description

technical field

[0001] The invention relates to the field of thermal simulators, in particular to an auxiliary device for a thermal simulation test of a round bar-shaped metal forging and a method for using the same. Background technique

[0002] To study the forging deformation process of round bar-shaped metals not only needs high deformation speed and high pressure, but also requires forging and deforming circular arc-shaped concave anvils of round bar-shaped samples. At present, in the thermal simulation test of Gleeble model, the movement speed of the motorized chuck is 1000mm / s, and the anvils used are all flat end faces, which can neither provide high-speed impact pressure for metal forging, nor provide radial deformation constraints for round bar forgings. Force, forging thermal simulation test of round bar-shaped metal can not be carried out. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, ...
