KraussMaffei Berstorff’s hydraulic tool centering system is suited for hose diameters ranging between 3 and 100 mm
At the IRC KraussMaffei Berstorff will exhibit a straight-through extrusion head with hydraulic tool centering system and X-ray measuring device.
This system, it says, will enable rubber hose producers to become more competitive by increasing productivity, improving product quality and minimising raw material consumption.
"After the IRC 2015, the hydraulic tool centering system for hose diameters ranging between 3 and 100 mm will be available to all our customers," said Frank Reineke, responsible for rubber process technology and development at KraussMaffei Berstorff.
"This system is an optimum solution for hose manufacturers wishing to produce hoses of identical wall thickness over a longer period of time as it ensures high reliability, unparalleled economic efficiency and premium quality. Retrofitting the hydraulic tool centering system in existing hose extrusion lines is also possible," he added.
The straight-through extrusion head is designed for minimum set-up times, high productivity and perfect product quality. In the front head area, the hose wall thickness is adjusted by an axially moveable die as in previous solutions. Radial centering is ensured by a hydraulic system that acts on the newly designed die holder, which substantially reduces the setting efforts during start-up and production, explained Reineke.
The X-ray measuring device, in combination with the tool centering system, replaces manual head adjustment with an automated process. The device continuously measures the wall thickness, eccentricity and outside diameter of rubber hoses and adjusts the hydraulic wall thickness centering system to one-hundredth of a millimetre using digital controllers.
