Abstract
The present invention relates to plastic forming apparatus, and is especially flexible forming apparatus with flexible roll for machining 3D workpiece. The flexible forming apparatus consists of work rolls, regulating mechanism, frame and work roll driving mechanism. Each of the adjustable flexible work rolls has several regulating mechanisms for curvature degree regulation. The adjustable flexible work rolls are arranged inside or outside the workpiece. The work rolls rotating while producing centrifugal or centripetal motion make the workpiece diameter decreased or increased. The frame is a double supported one or a cantilever one. The present invention can form 3D workpiece, and has high production efficiency and low production cost.

The objective of the invention is to change the traditional tubular or the processing mode of bar-shaped 3 D workpiece, a kind of flexible forming apparatus that uses flexible roll processing tubular or bar-shaped 3 D workpiece is provided.
Above-mentioned purpose of the present invention is achieved in that accompanying drawings is as follows:
A kind of flexible forming apparatus that uses flexible roll processing tubular or bar-shaped 3 D workpiece, comprise working roll, guiding mechanism, frame and working roll driving mechanism, described working roll has at least one to be flexible, adjustable flexible working roller, and the guiding mechanism that several can adjust its flexibility is set on each working roll.
Described flexible roll can constitute by two, an outside that is arranged in cylindrical workpiece, and one is arranged in the inboard.
The described working roll that is arranged in the inboard is passive bending roll or the simple and easy resilient roller that need not to adjust.This simple and easy working roll can be designed to have the stiff shaft core working roll of resilient sleeve, makes inboard working roll, and simplifies the structure of inboard working roll.
Described crooked working roll also can be by constituting more than two, and all uniform or all uniform along the workpiece periphery along the workpiece inside circumference.
Described frame is designed to dual-gripper formula or cantilevered.
The part of described dual-gripper open frame is designed to detachable, unload removable section after, can lift one or more working rolls and put or take out workpiece into.
The present invention has used for reference multi-point forming technique, the tubular or the bar-shaped workpiece that use flexible roll to replace traditional processing mode processing to have certain 3D shape, this technology is compared with traditional technology, low cost of manufacture, the cycle of formation of parts is short, save great amount of manpower and material resources, enhance productivity greatly.
