... by extrusion ( Ref 9.9 ). Figure 9.10 shows typical THF parts that require bending or preforming prior to hydroforming. When the geometry of the bent tube is designed correctly, not only can the tube be easily oriented into the hydroformed die cavity, but also the quality of the formed part...

... Abstract Roll forming is a process in which flat strip or sheet material is progressively bent as it passes through a series of contoured rollers. This chapter describes the basic configuration and operating principles of a roll forming line and the cross-sectional profiles that can be achieved...

... diffraction methods showed that the 304L coextruded tube typically exhibits compressive axial stresses on the surface of the cladding at the unbent section and tensile axial stresses in some areas of the bent section ( Ref 37 ). One interesting observation was made with a video camera used to record the air...

... lamellar nature. Moreover, on account of cold bending, the grains were elongated in the bent portion of the tube, signifying a buildup of higher levels of internal stress. With this result, the tube developed a tendency toward microfissures at the time of bending, ultimately leading to failure. The...

Therefore, they require more powerful equipment and more expensive dies than draw bending. In ram or press bending, rigid supports hold the tube as it is bent around a die on the press ram...
