Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As Figure 1-Figure 4, the utility model provides a kind of steel pipe bending apparatus, comprise base plate 1, pressure roller 2, live roll 7, rocking arm 6 and fixture, pressure roller 2 and fixture are all arranged on described base plate 1, described rocking arm 6 one end is rotatably connected on the central shaft of described pressure roller 2, live roll 7 is arranged on described rocking arm 6 lower end, and live roll 7 can rotate around described pressure roller 2 under the drive of rocking arm 6.Some pressure roller blocks 10 that pressure roller 2 comprises center fixed block 12 and is located at outside center fixed block 12, all pressure roller block 10 makeup ring shape and structures, the outside of pressure roller block 10 is provided with groove 9, each pressure roller block 10 is connected to expansion link, described expansion link is fixed on center fixed block 12, described live roll 7 is circumferentially with indent 8, and live roll 7 is arranged on described rocking arm 6 movably, and described fixture is arranged on outside pressure roller 2.
Center fixed block 12 is square, and each side is connected to expansion link described in, and described pressure roller block 10 has four pieces, and do not have pressure roller block 10 described in block to be quadrant camber, four pieces of pressure roller blocks 10 surround circular, and four pieces of pressure roller blocks 10 connect expansion link described in respectively.
Expansion link is telescopic cylinder 11, and the cylinder body end of telescopic cylinder 11 is fixedly connected with described center fixed block 12, and body of rod end is fixedly connected with described pressure roller block 10.Under the driving of telescopic cylinder 11, pressure roller block 10 can be made to move on base plate 1, thus increase the diameter of the annulus that pressure roller block 10 forms.
