2A12-T4(大规格)阶段变断面铝合金挤压型材拉伸工艺的研究

Study on Drawing Process of 2A12-T4(Large Size) Variable Cross-section Aluminum Alloy Extrusion Profile

通过对2A12-T4合金大规格阶段变断面铝型材拉伸工艺的试验,进一步掌握了这种型材从挤压到拉伸及精整时的尺寸变化规律,为今后该型材的批量生产积累了经验。

In this paper, the stretching process of 2A12-T4 aluminum profile with different section at the stage of large size is tested, and the dimensional change rule of this profile from extrusion to stretching and finishing is further mastered, which accumulated experience for the mass production of this profile in the future.
