A kind of high-precision radian roll bending equipment
Technical field
The utility model relates to cold bending equipment field, specifically a kind of high-precision radian roll bending equipment.
Background technique
Roll bending is that plate or profile are made a kind of its curved process, the basic principle of roll bending by the roll shaft rotated
A circular arc is determined for 3 points, so that plate is generated continuous plastic deformation using the variation and rotary motion of roll shaft relative position,
The workpiece of predetermined shape for a moment, the technology have been widely used in metal structure and other machine industries.
The basic principle of traditional bending roll machine is as shown in Fig. 2, and side roller axis 10 rotates clockwise and applies to workpiece oblique
On holding power, upper roll shaft 11 rotates counterclockwise simultaneously applies downward pressure to workpiece, using these three points, make workpiece bows at
Arc, in bending process, upper roll shaft 11 can be by moving up and down, and to change the crooked radian of workpiece, but this kind of equipment is using
When have the defects that it is certain, during processing, the bending of workpiece must since after one section of straight line, specifically,
At the beginning of processing, workpiece, which need to lean against, just can be carried out processing on following two side roller axis 10, certain due to having between two side roller axis 10
Distance, so the end of the workpiece of completion of processing can generate the straightway 12 of certain length, likewise, when terminating bending,
The end of workpiece can equally generate the straightway of certain length, since the presence of the straightway at workpiece both ends results in part workpiece
Processing technology become complex, for example, need to spend it is a large amount of shaping manually is carried out to the straightway at workpiece both ends, increase
Production cost, or must be removed from the straightway at both ends to guarantee the whole radian of finished workpart, cause the waste of material.
Currently, the hydraulic system of existing bending roll machine uses to be watched entirely in order to reduce the error of work pieces process as far as possible
Closed-loop control is taken, by grating scale and encoder constantly feeds back volume under pressure and workpiece is passed by displacement, is constantly carried out micro-
It adjusts, compared to open-loop control system, greatly reduces roll bending in this way into arc bring error, while also significantly improving
The stability of work system.In the prior art, Chinese patent CN206898129U discloses a kind of high-precision automatic roll bending and sets
It is standby, roll bending is carried out to the longitudinal of workpiece by bend wheel, the horizontal roll bending of workpiece is carried out by bending roll, is driven by driving wheel
Workpiece transports, and is oriented to by guide roller group to roll bending workpiece, prevents its sideslip, guarantees roll bending yield rate, but roll bending workpiece
Both ends there are still one section of longer straightway, still need to carry out subsequent processing to the both ends of workpiece, still there is production costs
The problem of height, waste of material.
