Patent number: 8028558Abstract: The invention presents method and apparatus for forming of large thin panels and similar parts having integral stiffeners at one side of a board. The method includes progressive forming of preheated billets into sculptured dies of corresponding length and width by a forging die of substantially identical width and short length with slightly inclined and flat forging surfaces providing a smoothly convergent working zone, and a periodical transfer of the sculptured die into the working zone between successive strokes of the forging die. Control of the material flow is performed by selection of a ratio of the working zone length to the billet thickness, variable contact friction at both dies and application of additional compressive forces to the billet at ends of the working zone. For semi-continuous processing of very long parts, the sculptured die is composed by plurality of sectioned elements.Type: GrantFiled: October 31, 2008Date of Patent: October 4, 2011Inventor: Vladimir M.

Patent number: 5850755Abstract: Methods and apparatus are described for the plastic deformation of flat rectangular billets. Simultaneous extrusion of two flat rectangular billets through a die having channels of equal cross-sectional area alters billet material structure, texture, and physicomechanical properties without altering billet dimensions. The extrusion system of the present invention prolongs die lifetime, increases punch stability, decreases punch working load and pressure requirements, eliminates the difficulties associated with lubricating movable parts of the die under high pressure and temperature, optimizes use of press space, and provides for automatic and independent ejection of extruded billets from the die. The methods of plastic deformation processing of flat rectangular billets in the present invention allow for the production of a variety of structural, textural, and physicomechanical properties previously unobtainable for large flat rectangular billets.Type: GrantFiled: February 8, 1995Date of Patent: December 22, 1998Inventor: Vladimir M.
