It sets including a bearing block 11 and the main shaft 1 being rotatablely connected with bearing block 11.
Wherein, bearing block 11 is fixedly connected with a master form mechanism 4.
There are one curved booms 2 for installation on main shaft 1.
Curved boom 2 is equipped with curved mold mechanism 3.
Master form mechanism 4 includes driving device 5 and the pattern 41 in the fixed plate of driving device 5.
Curved mold mechanism 3 includes clamping 31, curved mould 32 and driving device 5.
Clamping 31 is connect with the fixed plate of driving device 5.
Pipe fitting is across curved mould 32 and clamping 31.
Pattern 41 is set to pipe fitting side identical with clamping 31.
Curved mould 32 is arc-shaped curved die face close to 41 one end of pattern.
When bending, driving device 5 drives clamping 31 close to curved mould 32, so that pipe fitting be clamped, then clamping 31 and curved
It is that axle center is overturn that pipe fitting entirety, which is clamped, with main shaft 1 in mould 32, at the same time, the also picking-up under the driving of driving device 5 of pattern 4
Pipe fitting is compressed to curved mould 32, so that pipe fitting is carried out bending along curved die face, to be processed into scheduled shape.
In the present embodiment, driving device 5 is self-locking driving device.
As shown in Figures 2 and 3, driving device 5 include a cylinder 51 and with 51 body side of cylinder directly or
Connect fixed clamping plate 52.
There are one cylinder connectors 55 for installation on the output shaft of cylinder 51.
Cylinder connector 55 is connected with one piece of fixed plate 53 by one group of connecting plate component 54.
Connecting plate component 54 includes the first connecting plate 541, the second connecting plate 542 and third connecting plate 543.
First connecting plate, 541 one end is hinged with cylinder connector 55, the other end and the second connecting plate 542 and third connecting plate 543

The axis pin being passed down between the second connecting plate 542 and clamping plate 52 on, and since two the first connecting plates 541 are horizontal and are linked to be one
Line, third connecting plate 543 is almost nil by the downward pressure that hinge joint applies cylinder connector 55, thus constitutes one
Self-locking structure, fixed plate 53 can not move down.
When cylinder 51 actively bounces back, the state of two 541 levels of the first connecting plates and company's being aligned is destroyed, two first
The second connecting plate 542 is set to be connected respectively to cylinder with one end of third connecting plate 543 by hinge joint while connecting plate 541 forms angle
First 55 draw close, and connect the state of being aligned to destroy the second connecting plate 542 and third connecting plate 543, and then self-locking structure is destroyed, gas
Cylinder 51 makes fixed plate 53 move down by cylinder connector 55 and connecting plate component.
Using the self-locking driving device of above technical scheme, formed by the be hinged connecting plate component of composition of one group of connecting plate
One self-locking structure, cylinder by connecting plate component by fixed plate release it is in place after, even if mounting hole bears larger pressure,
Cylinder will not be caused to bounce back, thus overcome cylinder and ejecting the problem of back pressure in place is difficult to keep.Self-locking driving dress
It sets and can be used for substituting oil cylinder in the various structures for needing maintenance static thrust.
Using the bending mechanism of above technical scheme, a kind of drive of self-locking driving device as pattern and clamping has been used
Dynamic, self-locking driving device overcomes cylinder by a self-locking structure and is ejecting the problem of back pressure in place is difficult to keep, from
And instead of oil cylinder in the prior art.The bending mechanism not only simplifies structure, reduces it is not necessary that hydraulic power system is arranged
Cost, and pollution of the hydraulic oil to product and environment is also avoided, to be more energy-saving and environmentally friendly, meet wanting for clean manufacturing
It asks.And cylinder has elasticity during propulsion, speed can be used for during clamping to avoid clamping or pattern
Too fast either dynamics causes greatly pipe fitting to be pinched or deform very much.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
