摘　　要：根据一种驱动桥壳整体复合胀形的新加工工艺及其胀形装置,介绍了管坯变形的载荷需求,详细分析了管坯变形两次更换中芯缸的作业工序。然后,结合胀形成形的功能需求,使用合理的调速、调压、同步、平衡、缓冲和方向控制等液压回路,设计了复合胀形液压系统,系统拥有能耗低、发热量少、冲击小、稳定性好和运动精度高等特点。系统运行是左右水平缸和中芯缸Ⅰ、Ⅱ、Ⅲ共同作用,使九连杆机构做复合联动,再结合外模约束,进行加热开槽管坯的第一、二、三次胀形成形,得到驱动桥壳半成品。According to a new processing technology and bulging device for driving axle housing integral compound bulging,the load requirement of tube blank deformation is introduced,and the operation procedure of replacing the central hydraulic cylinder twice for tube blank deformation is analyzed in detail.Then,combined with the functional requirements of bulging deformation,a compound bulging hydraulic system is designed by using reasonable hydraulic loops such as speed regulation,pressure regulation,synchronization,balance,buffer and direction control.The system features low energy consumption,less heat generation,small impact,good stability and high motion accuracy.The operation of system is the combined action of left and right horizontal cylinders and central hydraulic cylinder I,II and III,the nine-bar linkage mechanism performs compound linkage.Then combined with outer mold constraints,the first,second and third bulging deformation of the heating slotted tube blank was carried out,and the semi-finished driving axle housing was obtained.
