摘要: 针对6063铝合金钎焊件在切削加工中的畸变问题,分析了6063铝合金钎焊件残余应力产生机理,对其进行不同温度的去应力处理,并对其硬度等性能进行检测。首先确定使用盲孔法测试6063铝合金钎焊件残余应力。在保证钎焊件材料状态T6态不变的前提下,通过验证去应力工艺参数,确定了6063铝合金的最佳去应力工艺参数为温度230 ℃,保温时间2 h,此时其硬度为69.8 HR15T。运用该去应力工艺参数,6063铝合金钎焊件残余应力消除率48.7%,有效解决了6063铝合金钎焊件在切削加工中的畸变问题。

Abstract: Aiming at the distoration of 6063 aluminum alloy brazed parts during cutting process, the mechanism of residual stress generation in brazed parts of the 6063 aluminum alloy was analyzed, and the hardness and other properties were tested after stress relieving at different temperatures. The blind-hole method was firstly selected to test the brazed residual stress of the 6063 aluminum alloy, then under the premise of keeping the material state T6 of the brazed parts unchanged, the stress relief process parameters were verified, finally the optimal stress relief process parameters of the 6063 aluminum alloy are determined as temperature of 230 ℃ and holding time of 2 h. Under such a process, the alloy hardness is 69.8 HR15T, the residual stress relief rate of the 6063 aluminum alloy brazed parts is 48.7%, and the distoration of the 6063 aluminum alloy brazed parts during cutting process is effectively solved.
