Study on Optimization of Forging Process Parameters for New Aluminum Alloy Building Fasteners

采用不同的始锻温度和终锻温度对新型铝合金建筑扣件试样进行了成形试验,并进行了耐磨损性能的测试与分析。结果表明:随始锻温度、终锻温度的增加,扣件试样的磨损体积先减小再增大,耐磨损性能先提升再下降。与420℃始锻温度相比,480℃始锻温度下试样的磨损体积减小38.71%;与300℃终锻温度相比,360℃终锻温度下试样的磨损体积减小了42.42%。扣件的锻压工艺参数优选为:始锻温度480℃、终锻温度360℃。

The forming tests of new aluminum alloy building fasteners were carried out by using different initial forging temperature and final forging temperature, and the wear resistance was tested and analyzed. The results show that with the increase of initial forging temperature and final forging temperature, the wear volume of the fastener specimen decreases first and then increases, and the wear resistance increases first and then decreases. Compared with that of the initial forging temperature at 420℃, the wear volume of the specimen decreases by 38.71% when the initial forging temperature is 480℃.Compared with that of the final forging temperature at 300℃, the wear volume of the specimen decreases by 42.42% when the final forging temperature is 480 ℃. The optimum forging process parameters of fasteners are initial forging temperature of 480℃ and final forging temperature of 360 ℃.
