ABSTRACT:
A compliant nozzle assembly for being mounted with respect to an extrusion module of an extrusion apparatus, wherein the nozzle thereof compliantly yields when forceably encountering a workpiece. A nozzle having a hemispheric base is biased against a seal washer of an adapter member so as to be pivotably sealed therewith. A locator bearing has an annular bearing bevel which is biasably seated into an annular seat bevel of the adapter member. When the nozzle forcefully strikes a workpiece such that the nozzle is caused to be pivoted at the seal bearing, the annular bearing bevel will become unseated from its normally seated position in the annular seat bevel. This displacement results in the locator bearing traveling axially along the nozzle toward its tip, having the effect of causing the annular bearing bevel to the returned to its normally seated position in the annular seat bevel. Thus, the nozzle is able to compliantly move in response to forceful contact with a workpiece, yet will resiliently return to its preset location as soon as the forceful contact is terminated.
