Title: Innovations by Leonard L Pollum
Introduction
Leonard L Pollum is a notable inventor based in Lapeer, MI (US). He has made significant contributions to the field of metal forming technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is titled "Conduction preheating for hot-formed sheet metal panels." This invention involves the annealing of work-hardened sheets of formable metal through thermal conduction. In this method, the sheet is placed on a heated lower platen to partially heat and soften it. An opposing heated upper platen is then brought close enough to contribute heat without constraining the sheet as it expands. The platens are subsequently brought close to the sheet to heat it to its forming temperature primarily through thermal conduction.
Another significant patent by Pollum is the "Extraction system for hot formed parts." This invention enables the distortion-free removal of a heat-softened sheet metal part from a heated forming surface. It utilizes strategically located and sized lift pads that are recessed in the forming surface of the hot forming tool. At the end of the stretch forming process, these pads are lifted in unison, without rotation, to carefully and uniformly strip the flexible part from the hot forming surface.
