METHOD FOR PRODUCING AXISYMMETRIC stamped BLANKS TYPE GLASSES AND CUPS OF SYSTEMS high strength aluminum alloy Al-Zn-Mg-Cu, doped with scandium and zirconium

摘要

1. A method for producing axially symmetric cup type stamped blanks and cups of Al-Zn-Mg-Cu system of high-strength aluminum alloy, doped scandium and zirconium, with a ratio of height to outer diameter H / D = 0,15-0,35 and a wall thickness to the outside diameter S / D = 0,05-0,1 slozhnokonturnym with bottom having thickening of different shapes and sizes, by hot plastic deformation in the die, comprising the steps that a cast cylindrical billet installed in the lower die - the matrix with the ejector deforms special curly m punch and wherein the deformation of the workpiece is carried out in two stages, including its upset and subsequent forming predetermined product wall profile and the bottom and performed in a single operation by topical application of the load, ensuring change of shape the workpiece due to intense high-speed plastic deformation with varying smoothly increasing levels of localization, the outer surface of bottom product is formed above the punch, arranged at a certain angle to the vertical axis of the matrix rotating at a constant speed, and the product wall and the inner surface of its bottom - rotating at the same speed with the matrix shaped pusher moving during deformation in a vertical direction upwards towards the punch with the controlled skorostyu.2. A method according to claim 1, characterized in that the angle of inclination of the punch to the vertical axis of the matrix amounts to 5 ° .3. A method according to claim 1 or 2, characterized in that the punch and die have similar multidirectional rotation speed of 200 r / min using its own synchronized n
