Sperrkeilanordnung für zweiteilige, mechanisch verbundene Dorne

摘要

A two-piece, mechanically connected mandrel assembly in which a locking wedge assembly serves to secure a tapered socket connection. The wedge assembly includes two long wedge segments, two short wedge segments, a bolt connecting the short wedge segments and a locking device to fix the bolt after proper torquing to secure the assembly. The two-piece, mechanically connected mandrel assembly is useful in the rolling or drawing of steel tubing or other metal constructs, and the four-piece locking wedge assembly both provides a secure connection and permits ready replacement of a worn work bar with a new work bar.
