The technical scheme that solves the problems of the technologies described above is: a kind of multidirectional steel pipe bending machine, comprise frame, bending tube forming mechanism, radius guiding mechanism and dynamical system, described bending tube forming mechanism is made of roller assembly I, roller assembly II and roller assembly III, described radius guiding mechanism comprises the oscillation system of adjusting nut, adjusting lever and being connected with bending tube forming mechanism with adjusting lever respectively, and roller assembly I, roller assembly II and the roller assembly III of described bending tube forming mechanism all adopt axial float roller assembly.
Further technical scheme of the present utility model is: described axial float roller assembly is made of roller body, bearing, roller shaft, jump ring, pressing plate, described roller shaft is the multidiameter that diameter is reduced to two ends gradually by the middle part, and the two ends of this roller shaft are installed on the frame respectively; Described bearing respectively with the roller shaft matched in clearance, and the inner side end of two bearings to the distance of roller shaft middle bench end face is respectively L1 and L2, the span of this L1+L2 is: 5mm≤L1+L2≤100mm; Described roller body is installed on the roller shaft by this bearing floating, and the jump ring and the pressing plate that are positioned at the bearing outside are installed on the roller shaft respectively.
Owing to compare with existing bending machine to the steel pipe bending machine more than the employing said structure, the utility model, have following beneficial effect:
1, can carry out the space multi-directional bending to steel pipe:
Because roller assembly I, roller assembly II and the roller assembly III of bending tube forming described in the utility model mechanism all adopt axial float roller assembly, this axial float roller assembly is made of roller body, bearing, roller shaft, jump ring, pressing plate, its middle (center) bearing and roller shaft are matched in clearance, make roller body that the moving range of L1, L2 can be arranged respectively on roller shaft to the left or to the right, therefore when the bend pipe operation, these three groups of roller assemblies can be adjusted its position automatically with the shape of steel pipe workpiece, has certain adaptivity, so can carry out the space multi-directional bending to steel pipe.
2, simple in structure:
Of the present utility model relatively simple for structure, promptly be on the basis that can only carry out crooked existing roller type bending machine originally to a direction steel pipe, by the bearing of change roller assembly and the structural design between the roller shaft, just can make the roller assembly have certain adaptivity, thereby can finish bending the multi-direction steel pipe in space.
3, easy to operate:
Because the utility model does not increase other complicated mechanism is arranged, so its operation is more convenient still with former roller type bending machine.
4, easy damaged steel pipe not:
Because three groups of roller assemblies of the present utility model all have certain adaptivity, therefore when buckling work, easy damaged steel pipe not.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic to the steel pipe bending machine more than the utility model is further described.
