Description
Technical field
The utility model relates to a kind of steel pipe process equipment, and more particularly, it relates to a kind of steel pipe straightening machine.
Background technology
Need to test to the linearity of steel pipe in steel pipe processing, the steel pipe bending to axial line needs to carry out straightening by steel pipe straightening machine to steel pipe.The curved support plate that existing steel pipe straightening machine generally includes hydraulic cylinder, arc pressuring plate, bracing frame and is connected with bracing frame, by hydraulic cylinder control arc pressuring plate stretch so that pressurize between curved support plate and arc pressuring plate steel pipe make steel pipe straightening.Such straightening mode needs to change arc pressuring plate and curved support plate according to processed diameter of steel tube, and the arc pressuring plate changed and curved support plate are usually because the error that exists in assembling process and gap are difficult to the linearity ensureing steel pipe.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of steel pipe straightening adapting to different-diameter, and can ensure the steel pipe straightening machine of steel pipe linearity.
For achieving the above object, the utility model provides following technical scheme: a kind of steel pipe straightening machine, comprise hydraulic cylinder, arc pressuring plate, bracing frame and the curved support plate be connected with bracing frame, described arc pressuring plate is connected with the output shaft of hydraulic cylinder, described curved support plate and arc pressuring plate are equipped with multilayer arc pad, described arc pad is arranged and mutually stacking with one heart, described arc pad comprises intrados and extrados, described intrados is provided with dovetail groove, described extrados is provided with dovetail projection, plugged by dovetail groove and dovetail projection between described adjacent arc pad.
By adopting technique scheme, arc pressuring plate and curved support plate can increase and decrease be connected arc pad at any time to adapt to the steel pipe of straightening different-diameter, dovetail projection is arranged at the extrados of arc pad by intrados dovetail groove being arranged at arc pad simultaneously, also steel pipe can not by the dovetail projection crimp of extrados when straightening can to make steel pipe, and between adjacent arc pad by dovetail groove and dovetail projection plug ensure that arc pad there will not be circumference rotate and radially slide thus ensure that steel pipe straightening time steel pipe linearity.
The utility model is set to further: described dovetail groove and dovetail projection are all arranged at arc pad both side ends.
By adopting technique scheme, make dovetail groove be positioned at arc pad both side ends, when straightening steel pipe, steel pipe not easily squeezes out corresponding convex epirelief due to the dovetail groove on intrados, ensure that the surface quality of steel pipe.
The utility model is set to further: described arc pressuring plate and curved support plate side are equipped with the locating piece for preventing arc-shaped pad sheet axial slip.
By adopting technique scheme, arc pad end face can be ensured by locating piece when dovetail groove and dovetail projection mutual grafting arc pad, when making steel pipe straightening, arc pressuring plate and curved support plate is stressed more even, effective dispersive stress, lifting means service life.

Detailed description of the invention
Referring to figs. 1 through Fig. 2, the utility model steel pipe straightening machine embodiment is described further.
A kind of steel pipe straightening machine, the curved support plate 4 comprising hydraulic cylinder 1, arc pressuring plate 2, bracing frame 3 and be connected with bracing frame 3, described arc pressuring plate 2 is connected with the output shaft of hydraulic cylinder 1, described curved support plate 4 and arc pressuring plate 2 are equipped with multilayer arc pad 5, described arc pad 5 arranges also mutually stacking with one heart, described arc pad 5 comprises intrados 9 and extrados 10, described intrados 9 is provided with dovetail groove 6, described extrados 10 is provided with dovetail projection 7, is plugged between described adjacent arc pad 5 by dovetail groove 6 and dovetail projection 7.Arc pressuring plate 2 and curved support plate 4 can increase and decrease be connected arc pad 5 at any time to adapt to the steel pipe of straightening different-diameter, dovetail projection 7 is arranged at the extrados 10 of arc pad 5 by the intrados 9 dovetail groove 6 being arranged at arc pad 5 simultaneously, also steel pipe can not by dovetail projection 7 crimp of extrados 10 when straightening can to make steel pipe, and between adjacent arc pad 5 by dovetail groove 6 and dovetail projection 7 plug ensure that arc pad 5 there will not be circumference rotate and radially slide thus ensure that steel pipe straightening time steel pipe linearity.
Described dovetail groove 6 and dovetail projection 7 are all arranged at arc pad 5 both side ends.Make dovetail groove 6 be positioned at arc pad 5 both side ends, when straightening steel pipe, steel pipe not easily squeezes out corresponding convex epirelief due to the dovetail groove 6 on intrados 9, ensure that the surface quality of steel pipe.
Described arc pressuring plate 2 and curved support plate 4 side are equipped with the locating piece 8 for preventing arc pad 5 axial slip.By dovetail groove 6 and dovetail projection 7 mutually grafting arc pad 5 time locating piece 8 can ensure arc pad 5 end face, when making steel pipe straightening, arc pressuring plate 2 and curved support plate 4 is stressed more even, effective dispersive stress, lifting means service life.
