APPARATUS FOR THE EXTRUSION OF PLASTIC PIPES OR PROFILES

摘要

The present invention relates to an apparatus for the extrusion of plastic pipes or profiles with - an extruder with an extruder flange; - an extrusion die with a die flange through which the extrusion die is detachably connectable with the extruder flange; - a fastening element with two halves which are arranged to embrace the extruder flange and the die flange; - a tensioning element in order to press the two halves of the fastening element against the flanges. An improved function can be achieved in such a way that the two halves of the fastening element are fastened swivelably on the extruder and that they are mechanically coupled in order to perform an oppositely directed swiveling movement.
