Patents by Inventor Andrei Viktorovich Vlassov

Andrei Viktorovich Vlassov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Flanging processes with radial compression of the blank stretched surface
    Patent number: 6928848
    Abstract: A method and tool for forming a hem flange. A larger radius bend is initially formed when a pre-hem flange is formed. A sharper radius bend is subsequently formed when the flange is formed. After the flange is formed, conventional hem forming methods and tools may be used to complete formation of a hem that may be used to join inner and outer panels.
    Type: Grant
    Filed: March 27, 2003
    Date of Patent: August 16, 2005
    Assignee: Ford Motor Company

  • Flanging and hemming process with radial compression of the blank stretched surface
    Patent number: 6865917
    Abstract: A method and tool for forming a hem flange pre-hem and a final hem on a sheet metal panel wherein elastomeric tooling elements are used to apply radial compression during a forming operation. The elastomeric tooling elements are compressed and apply pressure to a side of the sheet metal panel, for example an aluminum panel, that is stretched during a forming process step. A foil layer may be placed between the sheet metal blank and the elastomeric tooling element to reduce friction and further improve forming performance.
