| 摘 要： | 在铝合金阶段变截面八字形型材生产过程中,制品的侧臂间隙、爪板间隙和扩并口尺寸严重影响着整个型材的外形尺寸。在辊式矫直方法中,通过分析影响该制品各部分外形尺寸之间相互变化的规律,选择合理的配辊矫直方法,消除该制品不同的外形缺陷,在生产中取得了好的效果,使变截面型材的质量、成品率和生产效率都有较大的提高。

| Abstract: | The multi-stage cross-section aluminum alloy profile with shape of "V" has been produced.The interval between the arms and between the two feet of "V",the dimension expansion and contraction of the feet gap affect the profile counter seriously during extrusion.The dimension changing regularity of the profile counter during roll straightening process has been analyzed,and the rolls matching for straightening process have been optimized.Therefore the counter defects have been eliminated.The quality,yield and productivity ratio of aluminum alloy profile with multi-stage cross section have been increased greatly. |
