Title: The Innovative Contributions of Gottfried Siebenhofer
Introduction
Gottfried Siebenhofer is a notable inventor based in Vienna, Austria. He has made significant contributions to the field of engineering, particularly in the development of devices that enhance the functionality and safety of cutting machines. With a total of nine patents to his name, Siebenhofer's work reflects a commitment to innovation and practical solutions in industrial applications.
Latest Patents
Among his latest patents is a device designed to protect selective cutting machines against overload. This invention involves a selective cutting machine equipped with cutting tools, specifically cutting rollers, that are rotatably supported on a pivotable cantilevered arm. The cutting tools and the cutting arm are connected to separate drive mechanisms. A strain or deformation measuring sensor is placed on the pivotable cantilevered arm, delivering signals to an evaluation circuit. This circuit is connected via control lines to the drive mechanisms of both the cutting arm and the cutting tool, ensuring optimal performance and safety.
Another notable patent is the bit holder with a detachably fixed bit bushing. In this design, the bit holder is nonpositively connected to a bit bushing, adhering to a pressure per unit of surface area greater than 100 N/mm² between the conical outer surface of the bit bushing and the inner wall of the receiving bore of the bit holder. After the bushing is driven into the receiving bore, the conical outer surface of the bit bushing protrudes beyond the bore by an excess amount, enhancing the efficiency of the tool.
