Abstract
The utility model relates to an equipment used for plastic forming, in particular to a flexible forming device for manufacturing three dimensional work pieces with bendable rollers. The flexible forming device consists of working rollers, adjustment mechanisms, a frame and a working roller drive mechanism, wherein the working roller is a bendable and adjustable flexible working roller, and a plurality of adjustment mechanisms which can adjust the bending degree of each bendable roller are arranged on the bendable rollers. The working rollers are arranged inside or outside the tube or bar shaped work pieces, and can also be arranged with equal angle along the circumferential direction. When the working rollers spin, and make centripetal or centrifugal movement, the work pieces have diameter reduction or expansion deformation. The frame is designed into double supporting or cantilever type. The equipment can realize the forming of the three dimensional work pieces, and compared with the conventional processing modes, not only the production efficiency can be improved, but also the manufacture cost can be reduced.
