A method for superplastic forming of sheet metal parts and fast plastic

摘要

A method for superplastic and fast plastic forming of sheet metal parts which are substantially free of visual surface deficiencies, comprising the steps of:Heating of at least one of a metal shaping tool to a predetermined temperature range;Insertion of a blank from a lubricated metal stock to a molding surface of the metal mold;Urging of the blank on the a metal shaping tool, in order to form a element;Removal of the shaped element from the a metal shaping tool;Removal of metal deposits from the mold surface of the metal mold with the use of a cleaning device, the a programmable positioner, which has a brush assembly, which comprises a rotary drive motor, which rotatably supports a cylindrical brush, with the brush a plurality of radially extending metal wire bristles, which are spaced axially from the rotary drive motor and formed from the molding surface of the metal deposits to remove metal mold, wherein the metal precipitation on the molding surface of the metal mold during the shaping of the blank in a formation direction parallel to the direction of the metal flow during the shaping formed; andMovement of the cylindrical brush with the programmable positioner along a predetermined cleaning path, wherein the brush with the molding surface of the metal mold is engaged, in order to remove metal deposits of this, each of said metal wire bristles in the case of the rotation of the brush is moved in a respective plane which extends at right angles to the formation direction of the metal deposits is aligned.
