Title: The Innovative Contributions of Thomas W. Scherf

Introduction

Thomas W. Scherf is a notable inventor based in Vandergrift, PA, who has made significant contributions to the field of engineering and manufacturing. With a total of nine patents to his name, Scherf has developed innovative solutions that enhance the production processes of hollow articles.

Latest Patents

Among his latest patents is the "Apparatus for calibrating hollow nonsymmetrical multiplane extrusions." This invention includes a plurality of internal die elements that are inserted into a hollow article and expanded by a tapered plunger. This process outwardly reforms the hollow article into the desired size and shape. An external die restrains the outer surface of the hollow article during the reforming process. This apparatus is versatile and can be used on hollow articles that do not have a linear longitudinal axis. The design ensures that the surface-to-surface engagement between internal die members creates an interface that aligns with the straight portions of the inner surface of the hollow article, except for internal corners.

Another significant patent is the "Internal articulated mandrel for the stretch forming of elongated hollow." This invention provides an apparatus and method for the stretch forming of elongated hollow metal sections, such as aluminum extrusions. The apparatus utilizes a collapsible and expandable articulated mandrel positioned inside the hollow metal section. This mandrel supports the internal wall surfaces against reshaping forces during the stretch forming operation, preventing the formation of wrinkles and crimps in the walls.
