摘要
针对可热处理铝合金板材的热成形工艺窗口窄,以及固溶处理、专用模具及其成形装备等方面的诸多问题,通过对高强度钢板热冲压成形技术的借鉴和对比,并结合铝合金热冲压成形的塑性成形性能,从铝合金材料与成形工艺、热冲压生产线及主要冲压装备等方面,对铝合金热冲压成形技术进行了合理性探讨,提出目前铝合金热冲压成形技术所存在的问题及其所需专用热冲压模具的核心技术要求。此外,对国内外热冲压成形装备的发展状况进行了讨论和分析,并列举了其主要代表机型。通过对铝合金板材热冲压成形工艺和装备的合理性探讨,提出了铝合金热冲压技术的发展趋势,有助于该技术在我国的推广和应用。
For many problems of narrow hot forming process window, solution treatment, special die and forming equipment for heat-treatable aluminum alloy sheet, through the reference and comparison of hot stamping forming technology of high strength steel plate and combined with the plastic forming properties of hot stamping for aluminum alloy, the rationality of the hot stamping technology for aluminum alloy from the aspects of aluminum alloy material and forming process, hot stamping production line and main stamping equipment were discussed. The problems existing in the current hot stamping technology for aluminum alloy and the core technical requirements for its special hot stamping die were pointed out. In addition, the development statuses of hot stamping equipment at home and abroad were discussed and analyzed, and the main representative machines were listed. Through the discussion on the rationality of the hot stamping forming process and equipment for aluminum alloy sheet, the development trends of the hot stamping technology for aluminum alloy were put forward, which was helpful to the popularization and application of this technology in our country.
