Process for forming hollow member with complicated cross-section

A process for forming a hollow member with A complicated cross-section wherein a section of a tube blank first undergoes a bending deformation due to its internal pressure and bend moment generated by the upsetting of an upper die, and is then compressed to be molded under the support of the internal pressure. The process of the invention does not require the reshaping step at an increased pressure. The process can make a hollow member with a complicated cross-section formed under a low pressure, and solves a technical bottleneck relating to a conventional process for forming this kind of members that is subject to an ultrahigh pressure generator.

Method of hydroforming an extruded aluminum tube with a flat nose corner radius

A method of hydroforming a vehicle rail from an extruded aluminum tube includes the steps of positioning the extruded aluminum tube into a hydroforming die and partially closing the hydroforming die. Next is the step of applying a liquid under a first level of pressure to the extruded aluminum tube in the hydroforming die. This is followed by engaging an inner radius of a bend in the extruded aluminum tube with the hydroforming die before completely closing the hydroforming die and increasing the level of liquid pressure in the workpiece to a second level to form and hydro-pierce a part from the extruded aluminum tube.
