DIE FOR THE VOLUME DEFORMATION AND THE FORGED PIECE EDGING Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: die for the volume deformation and the forged piece edging has an upper plate with a punch, a lower plate with a pusher, a compound matrix, a traverse hard-mounted with the trimming matrix for axial displacement. The trimming matrix is made as ring with cutting edge forming in conjunction with the punch centering protrusion a molding impression with a seam groove. The inner section of the molding matrix interacts with the cutting edge of the trimming matrix with the aid of reciprocal motion drive made in the form of spring-loaded stepped screws and a pusher.
