METHOD AND SYSTEM FOR FORMING ALUMINUM ALLOY BLANK

The present invention relates to a method of forming a 6xxx or 7xxx series Al alloy blank is provided. The method comprises the steps of heating the blank to a solutionization (SHT) temperature, TSHT,for the alloy of the blank at a heating station and keeping the blank at said SHT temperature until SHT is complete, cooling the blank at a cooling station to an intermediate temperature, TITM, at which the kinetic movement for the alloy in the blank stops and at a cooling rate that is high enough such that re-crystallization in the alloy of the blank does not occur, forming the blank in a forming tool, quenching the formed blank to room temperature, TE, and artificially ageing the formed and quenched blank in an ageing station. The present invention further relates to a 6xxx or 7xxx series Al alloy blank forming system (1, 3). 本发明涉及提供一种使6xxx或7xxx系列Al合金坯件成形的方法。该方法包括以下步骤：将该坯件在加热工位处加热至该坯件的合金的固溶(SHT)温度T并且将该坯件保持在所述SHT温度下直到SHT完成，将该坯件在冷却工位处并且以足够高使得不会发生该坯件的合金中的再结晶的冷却速率冷却至该坯件中的合金的动力学运动停止的中间温度T，使该坯件在成形工具中成形，将成形的坯件淬火至室温T，以
