Publication number: 20200246855Abstract: A process to plastically deform a metallic tubular member includes heating a portion of the tubular member to at least 350 degrees Celsius, performing a feeding operation on the tubular member by applying axial force to one end of the tubular member to plastically deform a primary deformed portion of the tubular member, and subsequently creating one of a bent portion in the tubular member and a secondary deformed portion in the tubular member between the one end of the tubular member and the primary deformed portion.Type: ApplicationFiled: April 24, 2019Publication date: August 6, 2020Inventor: Tad V. Machrowicz

Publication number: 20190217363Abstract: This invention is related to a method to increase the strength of a metal stamping by supplying a metal blank which has the ability to strengthen in-situ during stamping to achieve sets of properties not expected and much higher based on the starting properties of the blank.Type: ApplicationFiled: December 21, 2018Publication date: July 18, 2019Inventors: Daniel James BRANAGAN, Craig S. PARSONS, Tad V. MACHROWICZ, Jonathan M. CISCHKE, Andrew E. FRERICHS, Brian E. MEACHAM, Grant G. JUSTICE, Kurtis Clark, Logan J. TEW, Scott T. ANDERSON, Scott LARISH, Sheng CHENG, Taylor L.

Publication number: 20150203246Abstract: A modular load bearing structure is configured from a plurality of structural members which are engageable with one another so as to define a load bearing structure having planar first and second faces disposed in a spaced apart plane parallel relationship. The structural members include engagement features which allow the members to be assembled into a load bearing structure. The members may be at least partially hollow structures and may be fabricated by blow molding. In some instances, the members may be multi-part members assembled from a plurality of separate elements.Type: ApplicationFiled: January 19, 2015Publication date: July 23, 2015Inventor: Tad V.

Patent number: 6959950Abstract: A vehicle bumper system defined principally by outboard and inboard elongate beams which project transversely across the vehicle. The ends of the front and rear beams are joined by connecting points which function as energy-absorbing fulcrums or hinges, with the remainder of the front and rear beams initially being free of direct structural connection. The front beam is outwardly curved so that the center portions of the front and rear beams define a gap therebetween. The rear beam has connections to the vehicle at two points spaced transversely inwardly from the end connections, which connections define inboard fulcrum or hinge points. The front and rear beams are each formed as elongate monolithic structures, such as of high strength steel, and have configurations which enable them to nest one within the other in the longitudinal direction of the vehicle.Type: GrantFiled: May 26, 2004Date of Patent: November 1, 2005Assignee: Pullman Industries, Inc.Inventors: Jeffrey L. Bladow, Tad V. Machrowicz, Steven N. Fidh
