摘要
从铸旋铝合金车轮的热旋压成形工艺出发,分析了A356材料强韧化原因,分析表明:热塑性变形可成为A356铝合金强韧化的新途径,以此为基础发展的铸旋成形工艺可满足汽车轮毂进一步轻量化的要求。分析了影响车轮旋压成形的温度、毛坯形状、模具结构等因素,对稳定旋压成形工艺具有实际指导意义。
The reason on strengthening and toughening of A356 cast aluminum alloy is analyzed from the cast plus hot spinning process of aluminum alloy wheels.The analyzed results show that hot deformation can be a new strengthening and toughening method and the cast plus hot spinning process developed based on this could fulfill the light weight demand of aluminum wheels.The factors of spinning temperature,blank shape and die structure to influence spinning are analyzed,It is important to steady the spinning process of aluminum alloys wheels.
