Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, a kind of hydraulic straightening machine, including the support portion 2 being placed in base 1 both sides, bottom the opposite sides of described support portion 2, two ends are equipped with lower wheel of correcting and fix device 31, being fixed with lower rectification wheel 3 by correcting the fixing device 31 of wheel, described wheel 3 of correcting is positioned at the middle position of base 1;Respectively being fixed with a hydraulic jack I 7 in the middle part of the opposite sides of described support portion 2, the top of hydraulic jack I 7 can turn and is connected to upper pressure wheel 4;Two ends, opposite sides top, described support portion 2 are respectively fixed with a telescoping mechanism 8, and the top of telescoping mechanism 8 is fixed with web erection device 5;Described support portion 2 is fixed with hydraulic jack III 9 lower rectification on the upside of the fixing device 31 of wheel, and the top of described hydraulic jack III 9 is fixed with location bearing 6, and position, bearing 6 lower side, described location is in same level line with lower wheel 3 positions, top side of correcting;Being fixed with hydraulic floating roller-way 10 outside two ends, described support portion 2, the end face of described hydraulic floating roller-way 10 is on same level line with the lower end face correcting wheel 3.
Further, described upper pressure wheel 4 is frustum cone structure, and the side sectional area near support portion 2 is big, and the side sectional area away from support portion 2 is little, when correcting perpendicularity operation, can be adjusted according to different size steel.
Further, described web erection device 5 is two bearings 51 up and down connected by connector 52, is connected to the top of telescoping mechanism 8 in the middle part of connector 52, by treating the pressure of corrective piece both sides, and the perpendicularity of rectifiable web and flange plate.
Preferably, described telescoping mechanism 8 is hydraulic jack II 81, can adjust rapidly web erection device 5 by hydraulic jack II 81.Additionally, by another embodiment, as it is shown on figure 3, described telescoping mechanism 8 is screw handle 82, can accurately adjust web erection device 5 by screw handle 82, and regulate for rigidity, error is little.
Preferably, described upper pressure wheel 4 is hard nylon material, both can ensure compactness, it is possible to protect steel to be processed, reduce its degree of wear.
During hydraulic straightening machine work, first adjust hydraulic jack III 9, make the location bearing 6 of both sides be close to outside steel flange plate, it is ensured that steel flange plate centrage is consistent with the centrage of lower rectification wheel 3;Then hydraulic jack I 7 is adjusted, steel flange plate is close on the lower edge making upper pressure wheel 4, guarantee that lower rectification wheel 3 is close in steel flange plate bottom surface, for the steel that flange plate is thicker, compacting is got final product by the lower small cross sections correcting wheel 3, for the steel that flange plate is relatively thin, also can compacting by the lower larger cross-section correcting wheel 3;Finally adjust hydraulic jack II 81, or adjust screw handle 82, by rotatable handle adjust screw mandrel put in distance, make the bearing 51 in two coxostermum erection devices 5 press steel web, make web stress be perpendicular to steel flange plate;Start hydraulic floating roller-way 10, make steel slowly mobile to all having corrected.
In sum, the present invention is simple to operate, and effect is obvious, improves the speed of correction welded H section steel, T-steel, reduces processing cost, simultaneously quality and have also been obtained guarantee.
