Title: Innovations of Donald E. Krintzline
Introduction
Donald E. Krintzline is a notable inventor based in Tiffin, Ohio, with a remarkable portfolio of six patents. His work primarily focuses on advanced forming processes that enhance manufacturing efficiency and precision.
Latest Patents
Among his latest innovations are two significant patents related to point forming processes. The first patent describes a progressive forming machine equipped with die and tool units. One of these units is designed to slide a limited distance along its axis and is biased by a spring force towards the other unit. This design ensures that the end faces of the units, which have a smooth surface finish, press against each other effectively. The unique configuration allows for high contact pressure, which prevents leakage of extrusion/cooling oil during hydrostatic trapped extrusion, enabling the shaping of workpieces beyond conventional cold-forming limits.
The second patent also focuses on a set of tooling for a progressive forming machine. This tooling comprises die and tool units with internal complementary cavity portions for receiving a workpiece. Similar to the first patent, one unit slides a limited distance and is spring-biased towards the other unit. The design ensures that the end faces maintain a high contact pressure, effectively restraining leakage during the shaping process.
