A structural part includes a plate-shaped base body and ribs that extend longitudinally approximately parallel to one another, and that are joined integrally to and protrude orthogonally from the base body. In a shaping method, the structural part is shaped by particles of blasting or peening shot, which strike the surface areas of the structural part at a high velocity to cause a plastic deformation thereof. Opposite surface areas of the ribs, located on opposite longitudinal sides of each rib, are simultaneously subjected to the action of particles of the blasting shot. An apparatus to perform the method includes two nozzles arranged facing toward one another with the rib therebetween, to form two jets of the blasting shot particles directed toward one another at the rib.
A method for shaping a structural part including a plate-shaped base body and ribs which are longitudinally extended, are approximately parallel to one another, are joined integrally to the base body, and protrude from the base body in an orthogonal manner, said method comprising forming and directing two jets of free-flying particles of blasting shot so as to respectively strike two opposite surface areas of one of the ribs and produce a plastic material shaping, wherein the opposite surface areas of the rib are located on opposite longitudinal sides of the rib, and the two jets are directed simultaneously at the two opposite surface areas.
An apparatus for shaping a structural part that includes a plate-shaped base body (5) and ribs (6) which are longitudinally extended, are approximately parallel to one another, are joined integrally to the base body (5), and protrude from the base body (5) in an orthogonal manner, wherein the apparatus is adapted for conveying particles of blasting shot onto surface zones of he structural part (4) where the particles produce a plastic material deformation, wherein the apparatus comprises at least two nozzles (1a/1b) that are respectively adapted to convey and produce a directed delivery of two particle jets (3a, 3b) of the free-flying particles of blasting shot, wherein the two particle jets (3a, 3b) are directed toward each other, and wherein the nozzles (1a, 1b) are arranged facing toward each other at a spacing distance from each other that is larger than a thickness of the rib (6).
A method of shaping a structural part that includes a plate-shaped base body and a rib joined integrally to, extending longitudinally along, and protruding outwardly from said base body, wherein said method comprises the steps:
