Cold rolling machine

摘要

The machine has one or more, and preferably two, additional tools (3) formed as profiling rollers for rolling-in of a recess and rotating with the main rollers (1), and are axially movable on their mountings (7,8) by means of spring pins (5). For torsion compensation for the additional tools their RPM is decoupled from the RPM of the rollers. The torsion compensation is provided by a slipping clutch with a spring-loaded friction lining between the tool holder (4) and housing sleeve (6).
