Research on experiment of size prediction of thick-walled tube without mandrel by open-die cold extrusion;

Research on improving prediction accuracy of maximum reduction by open-die cold extrusion;

Analysis of process parameter of open-die cold extrusion with upper-bound method

Maximum reduction when deep tine taper hole part is formed by open-die extrusion is defined.

In the paper, maximum reduction when deep tine taper hole is formed by open-die extrusion is defined.

In the paper, the forming limit was depicted by analysis of the deep tine taper hole is formed by open-die extrusion.

Maximum and minimum critical rates of deformation in open die extrusion are discussed on the basis of the slip field theory and the upper bound theory of plane state plastic deformation.

Study on precise cold extrusion technology of 6061 Al-alloy splines shell;

Failure analysis on fissuring of high-speed steel cold extrusion die plate;

Design of cold extrusion die for axle sleeve with internal saw tooth;

We discuss the 3D cracks around cold-expanded holes and simulate their interference prestress release using the engineering software of ANSYS to study the effect of the interference prestress release on stress intensity factors(SIFs) at crack tips.

Based on the character of the extrusion working and the category of the extrusion forming,the shape、the dimension and the deformation degree of the tubular component with oral part having flange are analyzed.

And open-die forward extrusion is a more advanced way of deforming spline.
