Abstract
The utility model discloses a pipe bending machine which comprises a machine frame. A pipe bending mechanism is arranged on the machine frame. The pipe bending mechanism comprises a rolling wheel I, a rolling wheel II and a rolling wheel III. The rolling wheel I is driven by a hydraulic oil cylinder which is arranged at the upper end of the machine frame and stretches in the up-down direction. The rolling wheel II and the rolling wheel III are driven by hydraulic cylinders of the rolling wheel II and the rolling wheel III, and the hydraulic cylinders are arranged on the left side and the right side of the machine frame and stretch in the left-right direction. The horizontal heights of the rolling wheel II and the rolling wheel III are equal. The projection in the vertical direction of the rolling wheel I is placed between the rolling wheel II and the rolling wheel III. The pipe bending machine has the advantages that during using, the relative positions of the rolling wheel I, the rolling wheel II and the rolling wheel III can be freely adjusted under pushing of the hydraulic oil cylinder, so that the bending path of a pipe is changed, pipe bending machining at various angles is achieved, and equipment is convenient to use and high in adaptability.
Description
Technical field
The utility model belongs to angle pipe equipment technical field, relates in particular to a kind of bending machine.
Background technology
Supporting little steel pipe, the occasions such as handrail tube of stair activity side on the steel pipe of the hydroelectric project that people will do, large-scale power transformer equipment, all there is the use of bend pipe, these metal tubes generally all need interim making in use, and the bending angle of the different needed bend pipes of occasion is different.Current bending machine bending angle is single, can not meet actual needs.
Utility model content
The utility model provides a kind of bending machine that can arbitrarily regulate bending angle for the defect of above-mentioned prior art.
The technical solution adopted in the utility model is: a kind of bending machine, comprise frame, frame is provided with pipe bending mechanism, described pipe bending mechanism comprises and rolls wheel I, rolls wheel II and roll wheel III, rolling wheel I drives by being located at the frame upper end flexible hydraulic jack of above-below direction, roll wheel II and roll wheel III and drive by being arranged on separately the flexible hydraulic cylinder in left and right, the frame left and right sides, roll wheel II and roll wheel III level height and equate, and the projection of rolling wheel I vertical direction is being rolled wheel II and rolled between wheel III.
Roll wheel I, roll wheel II and roll wheel III edge and be equipped with the arc groove matching with tube outer wall shape, and the arc central angle of arc groove is 180 °, the width of arc groove equals the diameter of pipe.During bending, roll wheel and coordinate and contact with tube outer wall, can effectively prevent the excessive local deformation causing of pipe local pressure, improve the quality of products.
The both sides of the edge of described arc groove are provided with edge backplate, and the distance between edge backplate equals the diameter of pipe.When edge backplate being set can reducing to bend there is the deformation of flat cross direction in tube bending place.
The beneficial effects of the utility model are: during use, roll wheel I, roll wheel II and roll wheel III can arbitrarily regulate the relative position between three under the promotion of hydraulic jack, thereby change the bending path of pipe, realize the processing of multiple angles bend pipe, equipment is easy to use, strong adaptability.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is edge backplate schematic diagram.
Shown in figure: 1, frame, 2, roll wheel I, 3, roll wheel II, 4, roll wheel III, 5, hydraulic jack, 6, pipe, 7, edge backplate.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
A kind of bending machine as depicted in figs. 1 and 2, comprise frame, frame is provided with pipe bending mechanism, described pipe bending mechanism comprises and rolls wheel I, rolls wheel II and roll wheel III, rolling wheel I drives by being located at the frame upper end flexible hydraulic jack of above-below direction, rolling wheel II and rolling wheel III has and is arranged on separately the flexible hydraulic cylinder in left and right, the frame left and right sides and drives, and roll wheel II and roll wheel III level height to equate, and the projection of rolling wheel I vertical direction is being rolled wheel II and rolled between wheel III; Roll wheel I, roll wheel II and roll wheel III edge and be equipped with the arc groove matching with tube outer wall shape, and the arc central angle of arc groove is 180 °, the width of arc groove equals the diameter of pipe; The both sides of the edge of described arc groove are provided with edge backplate, and the distance between edge backplate equals the diameter of pipe.
Certainly the enforcement of the present embodiment also needs feed mechanism and hydraulic power unit, and these are prior art, do not repeat them here.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
