现代汽车车身冲压成形新技术

New Stamping Techniques for Auto Body

汽车制造业正处在轻质、节能的市场需求压力下。为了顺应形势,汽车制造商从材料研发、设计、制造等方面做出不懈的努力,本文就现代汽车车身冲压成形新技术进行了阐述。包括铝材的空气辅助成形法、钢材的多滑块多工位压力机的冷成形、冲压硬化(热冲压)成形、使用双滑块多工位压力机冷成形、首台为液压机其余为机械式压力机的组合式冷成形等,以及如何在成形过程中创造高强度工件。

New stamping techniques for modern auto body have been introduced, including air-assisted forming technique of aluminum alloy, cold forming technique with multi -slide transfer presses or hybrid lines, press hardening technique （hot stamping） ;cold forming technique with a double-slide transfer press, and cold forming technique with a hydraulic lead-off press and mechanical follow-on presses.The way to create workpieces of high strength in forming process has been put forward.
