中文摘要:分析讨论了银铜合金连续挤压工艺特点及挤压温度、挤压轮转速、挤压比、溢料间隙对连续挤压制品质量的影响。通过理论分析和计算,确定了银铜连续挤压的挤压温度为480~500 ℃;而合理的挤压轮转速需根据挤压温度来选择。不同工艺下制品质量的结果分析也证实也这一点。
英文摘要:The technological specificity of the continuous extrusion forming for Ag-Cu alloy and the effects of several process parameters, such as extrusion temperature, extrusion wheel rate, extrusion ratio and flash gap, on the process were analyzed and discussed. Based on theory analysis and calculation, the extrusion temperature of continuouse extrusion process for Ag-Cu alloy was given, it was about 485~500℃; and the proper extrusion wheel rate could be confirmed according to the extrusion temperature. At last, it was confirmed by analysing the qualities of products under different processing parameters.
