Paper Title:
Experimental Studies on Cold Extrusion of Thin Wall Ultra-Deep Blind Hole about 7A04 Recoil Spring Tube
  Abstract

This document introduces tentative designs of the cold extruding of thin wall ultra-deep blind hole about 7A04 recoil spring tube, its technical process and experimental result and analyses the existed problems and the reasons. These experimental studies have reference value for taking cold extrusion shape of 7A04 and ultra-deep hole.
