摘要/Abstract

摘要：

根据胀-压成形汽车桥壳新工艺，初始无缝钢管经缩径、液压胀形及压制成形后得到带有后油盖及附加前盖的桥壳样件，切除前盖后获得桥壳产品，附加前盖的大小不仅影响材料的利用率，对管坯的压制成形性也有重要影响。针对某小型汽车桥壳，设计了三种不同尺寸、形状的附加前盖，利用有限元分析软件ANSYS模拟了不同附加前盖时桥壳样件的缩径、胀形及压制成形全过程，对比分析了桥包部分的成形性及端部翘曲量，确定了附加前盖的合理尺寸范围。在普通液压机上成功试制出桥壳样件，实际测量了其外形参数，并与模拟值进行了比较，证明了设计方法的可行性。

Abstract:

According to the bulging-pressing deforming new process,an initial seamless steel tube was made into automobile axle-housing blank with additional front-dome after diameter reducing, hydroforming and pressing, and the axle-housing can be gotten once the front-dome was removed. The additional front-dome affected the material utilization and the bulging-pressing formability. For a small axle-housing, three front-domes with different shapes and sizes were designed, the whole reducing, bulging and pressing deforming processes were simulated with software ANSYS, the reasonable size range for additional front-dome was given by analyzing the formability of dome part and ends buckling. The axle-housing blank was produced successfully with a common press, and the design method was proved to be reasonable comparing shape parameters with simulation results.

Key words: automobile axle-housing, bulging-pressing deforming, additional front-dome, formability
