His work focuses on improving processes and apparatuses for creating hollow metal articles, showcasing his expertise in engineering and innovation.
Latest Patents
Among his latest patents, one notable invention is the "Methods of and apparatus for forming hollow metal articles." This patent addresses the hydroforming of hollow metal articles in a die, specifically through pressure-ram-forming procedures. The method aims to decrease cycle time while ensuring acceptable product properties and avoiding failures. By utilizing finite element analysis, the process is modeled to establish a pressure-time history that optimizes the forming operation. This history is then transferred to a computer that controls the forming process, incorporating thermocouple and continuity sensors for active feedback.
Another significant patent is the "Methods of and apparatus for pressure-ram-forming metal containers and the like." This invention describes a method for forming bottle-shaped or contoured metal containers by subjecting a hollow metal preform to internal fluid pressure. The preform expands against the die cavity wall, while a punch is advanced by a backing ram to displace and deform the closed end of the preform. The process involves independently controllable internal and external positive fluid pressures, allowing for precise control of the strain rate.
