铝合金连杆模锻工艺研究

Study on the link of aluminium alloy die-forging technology

通过分析铝合金模锻工艺的特点、模锻过程中易产生的缺陷以及应该注意的问题,根据开式模锻成形理论和连杆零件图的要求,结合铝合金连杆锻造的技术和特点,对自行车铝合金连杆锻造工艺进行具体分析,确定了合理的铝合金连杆模锻工艺。绘制了计算毛坯截面图、锻件图,并进行了锻模设计,确定了制坯工步及模锻设备。同时指出在锻造过程中应该注意的问题以及相关的预防措施。

Based on the analysis of the aluminum alloy forging features easy forging process and the deficiencies should be noted,under the open-die forging parts theory and linkage map,combining link forged aluminum alloy technology and features ,bicycle link on the forging process for a specific analysis, determine a reasonable link alloy forging technology. Drawing rough calculation section map, forging map and forging die design,decide on the size and material blocking step of the process and equipment. Forging the same time that the process should pay attention to the issue and the relevant preventive measures.
