Abstract
Disclosed is a free bending forming device having a variable length of a bending deformation zone (defined as A value) capable of processing tubes of different outer diameters, including a bending forming module, clamping and fixing modules and a spherical bearing. Clamping mechanisms of the bending forming module and the clamping and fixing modules possess integrated radial freedom of motion and circumferential freedom of motion of clamping jaws, meeting the requirements for clamping tubes with different outer diameters. Positions of arc-shaped limiting blocks and clamping support seats are adjusted through the clamping and fixing modules to change a magnitude of A value during the forming process. According to the present disclosure, the efficient 'one-die-for-multiple-tubes' processing of the free bending forming device for tubes is realized, saving the time and cost associated with die replacements.
