Research on Material Properties and Heat Treatment of Clamping Blocks

Abstract:

This paper briefly introduces the basic component of dismantle pillar machine, respectively analyzes the structure of rotating hydraulic clamping device and fixed hydraulic device. Here mainly discussed hardenability carburizing steels 20CrNi3 that selected for clamping block, after carburizing, quenching and low-temperature tempering, obtains mechanical properties as following, intensity limit 950Mpa, yield limit 750Mpa, expanding rate 11%, section shrinkage rate 55%, impact toughness 90J.cm-2, surface hardness HRC58-63. The paper points out that the surface abrasion resistance and center impact resistance of clamping block is obviously better than surface hardening medium-carbon steel, and lamping block has a higher flexural fatigue performance. 40Cr is selected to make locating sleeve, it was quenched and tempered. The steering parts of dish-shape spring is chromalized on surface, so it can resist bending, twist and impact, its surface abrasion resistance is high and service life is long.
