The specific embodiment
Further specify the particular content of the present utility model and the course of work thereof below in conjunction with the accompanying drawing illustrated embodiment, but the setting of working roll not only is confined to the arrangement form in the accompanying drawing.
Among the embodiment with reference to figure 1, according to desired sheet material 3D shape, the adjusting rod 7 of regulating guiding mechanism 2 by manual control or digital control system makes 6 pullings of opening bearing or compacting flexible working roller make its flexural deformation; Can be provided with expansion bend in flexible working roller one or both ends, make its retractable when transferring shape, can fix after the accent shape, prevent that axial and circumferential from producing relative displacement.Simultaneously, for the distortion that makes the flexible working roller is easier, the lower bearing bracket of equipment can make all working roller whole mobile, makes the height and position of working roll at one's best.The working roll group is distorted under the effect of high pulling torque and anti-pine distortion in order to reduce, at anti-distortion of its non-shaped region installment work roller and anti-loose device 4.Transfer shape to finish, place work piece 3, and top working roll 1 is compressed on the workpiece by upper spider, when working roll rotates under the driving mechanism effect, workpiece is produced vertically move, can make workpiece produce linear deformation and transversely deforming by increasing drafts, thereby realize three-dimensional curve generation.
Among the embodiment with reference to figure 2, still top working roll 1 is compressed on the workpiece by upper spider.Can make the workpiece rotation, and produce distortion; When two sections working rolls rotate under the driving mechanism effect synchronously in the same way, workpiece is vertically moved, and produce distortion; When two sections working rolls under the driving mechanism effect during asynchronous rotation, workpiece is existing to vertically move and rotatablely moves, and realizes complex deformation simultaneously.
Among the embodiment with reference to figure 3, piece-holder and rotating mechanism 5 are compressed on the workpiece, and it is rotatablely moving of axle center that workpiece 3 is produced with piece-holder and rotating mechanism 5, and produces distortion.
Among the embodiment with reference to figure 4, piece-holder and rotating mechanism 5 are compressed on the workpiece, and it is rotatablely moving of axle center that workpiece 3 is produced with piece-holder and rotating mechanism 5, and produces distortion.
Workpiece 3 produces distortion by the compacting and the rotation of working roll, and can progressive forming, and it is just passable that the size of deformed shape and deflection only need be adjusted bending of work roll and drafts.
The quantity of working roll is formed by two at least, adopts three working rolls just can obtain good forming effect, and the many more forming effects of its quantity are good more certainly, and its arrangement can be arranged according to actual needs.
