一种铝合金细径薄壁管材的冷加工成型方法
摘要：
本发明公开了一种铝合金细径薄壁管材的冷加工成型方法，包括以下步骤：一、再结晶退火调质处理：采用真空炉或保护气氛下的电阻炉对铝合金管坯进行再结晶退火调质处理；二、表面润滑：在经再结晶退火调质处理后的铝合金管坯外表面上均匀涂覆一层MoS2乳状润滑剂或石墨乳状润滑剂；三、拉拔成型：采用拉拔设备对经表面润滑后的铝合金管坯进行多模拉拔处理，直至获得需成型的铝合金细径薄壁管材；四、后续处理：对拉拔成型的铝合金细径薄壁管材进行表面清洗、矫直和定尺处理，获得铝合金细径薄壁管材成品。本发明加工步骤简单、实施方便、加工成本低且加工效果好，能有效解决铝合金细径薄壁管材的加工难题。
摘要（英）：

The invention discloses a cold-processing molding method of a thin-diameter thin-wall aluminum alloy tubular product. The method comprises the following steps: (1) recrystallization annealing quenching tempering: adopting a vacuum furnace or a resistance furnace under protective atmosphere to carry out recrystallization annealing quenching tempering on an aluminum alloy tube blank; (2) surface lubrication: uniformly coating a layer of MoS2 emulsion lubricant or graphite emulsion lubricant on the outer surface of the aluminum alloy tube blank after the recrystallization annealing quenching tempering; (3) drawing and molding: adopting drawing equipment to carry out multi-die drawing treatment on the aluminum alloy tube blank after surface lubrication until obtaining an thin-diameter thin-wall aluminum alloy tubular product to be molded; and (4) subsequent treatment: carrying out surface cleaning, straightening and scaling treatment on the thin-diameter thin-wall aluminum alloy tubular product molded by drawing and obtaining a finished thin-diameter thin-wall aluminum alloy tubular product. The invention has simple processing steps, convenient implementation, low processing cost andgood processing effect and can effectively solve the problem for processing the thin-diameter thin-wall aluminum alloy tubular product.
