Abstract
The present disclosure is directed to a centering device for shaping tools for extrusion presses, wherein an outer mandrel together with an inner mandrel define a through gap for plastic extrusion material which device has a plurality of centering members supported on the outer mandrel which are distributed over the periphery of a radial plane and which are adjustable in the radial direction and which are constructed in the form of push rods guided for radial displacement. Each push rod (6,106) has associated therewith an individually adjustable drive, an adjustable lever (7,107) supported for pivoting on the outer mandrel and which are actuable by means of a tightening device (8,108) and form a transmission gear for applying the tightening force. Each adjustable lever is in direct engagement with its push rod in the region between its pivot bearing (13,113) and the point of action of its tightening device whereby the pivotal axes of the adjustable levers (7,107) are aligned parallel to the longitudinal central axis (10,110) of the shaping tool.
