Abstract：

For the problems that the current complex semi-tube parts are difficult to be formed and the forming quality is poor, a forming process of hydrforming was proposed to solve the forming problems of complex semi-tube parts. Based on the orthogonal test and numerical simulation software, according to the wall thickness analysis of simulation results for different test schemes, the best forming parameters of hydroforming for complex semi-tube parts were obtained with the chamber pressure of 15 MPa, die corner radius of 15 mm, punch friction coefficient of 0.1 and die friction coefficient of 0.1. Then, a structure model of punch port with the process compensation surface of paraboloid-shaped transition was established, and the optimal loading path of chamber pressure was determined as PPB mode. Furthermore, the hydroforming of complex semi-tube parts for aluminum alloy 5A02-O was verified by process test. The results show that the hydroforming process can effectively solve the forming problems of complex semi-tube parts, and the minimum wall thickness of formed parts is 1.65 mm which meets the industrial requirements.
