REMOVABLE MOUNTING OF THE ROLLING MACHINES’ WORKING ROLLS

Abstract

The work is focused on the design solution of fixing the exchangeable working rolls into cross-wedge rolling machine. The tools are clamped to the cylinders. In case of technology change, the tools must be replaced. Tools can be changed directly on the machine, this is a non-productive time. Another way to change tools is to replace entire cylinders. The diameter of the rollers is large, so the rollers themselves cannot be pulled out through the side hole, as is the case with a rolling mill. There are several ways to connect the middle part of the cylinders to the pins located in the stands. The work compares connections with a lid and a square or cylindrical shaft and variants in a single-sided extension able shaft with a conical or spherical surface. The aim of the work is to compare the stiffness of connection methods.
