Description
Technical field
The present invention relates to the finishing plant equipment of the processing technique field of metal pipe material in the metallurgical industry, particularly metal pipe material.
Background technology
Along with the development of world industry, the industrial expansion that particularly recovers the oil, the oil well pipe manufacturing has also obtained swift and violent development.But along with continuing to increase of oil mining difficulty, geological conditions constantly abominable.Because high grade of steel heavy wall tubing has good sealing, advantage such as connectivity, easy operability, so the market of Gao Gang-level heavy wall tubing reliably develops shape rapidly and becomes heavy.So-called heavy wall tubing promptly needs in the steel pipe's production process the thickening of steel pipe two ends, forms two pluckings, middle thin dumbbell shapeds, makes heavy wall tubing can have inevitable two ends straightening blind area when aligning like this on common straightener.Therefore, satisfy the requirement of API 5CT regulation in order to guarantee heavy wall tubing total length linearity, steel pipe also must carry out the part aligning of pipe end blind area after aligning usually.But the aligning of heavy wall tubing end is to be difficult to deal with problems always.
The pipe straightener of prior art generally adopts cross-roll straightening machine, because smoothing roll is in tilted layout, so steel pipe is made spiral motion all the time in the aligning process, steel pipe carries out repeatedly alternating bending between smoothing roll, finishes the aligning of steel pipe.But for the aligning of heavy wall tubing end, cross-roll straightening machine is also powerless.Research institution is abroad also arranged, utilize the photoelectric sensor technology, in the aligning process of steel pipe, along with the variation of caliber, utilize sensor to realize the adjustment of the distance of straightener up-down rollers, when the end is passed through, apart from increasing, allow head pass through up-down rollers, by after depress smoothing roll again.But this situation in fact end can reach the purpose of aligning steel tube end part, can only align body portion.Therefore aligning problem in the end of heavy wall tubing is a technical barrier always.
Summary of the invention
The object of the invention is to provide can eliminate straightening blind area, particularly can be to the end-thickened steel-tube straightening device of two ends heavy wall tubing body and two ends finishing aligning.
The present invention includes base, on base, be disposed to few two groups of carrying rollers along its length, two steel pipe fulcrum blocks that can slide along the base length direction are set respectively along the homonymy of base length direction, the base opposite side relative with the steel pipe fulcrum block arrange with described two steel pipe fulcrum blocks at conplane jacking block, the rear end of described jacking block is connected with a vertical hydraulic cylinder with the base length direction.
The steel pipe that needs finishing to align enters on many group carrying rollers by feed mechanism, finds the tube bending position by rotation, moves by the automatically controlled carrying roller rotation drive steel pipe front and back on carrying roller that make.Because two steel pipe fulcrum blocks can slide along the base length direction respectively, therefore, can adjust two positions of steel pipe fulcrum block on base arbitrarily according to bending length, the bending position of steel pipe, adjust two distances between the steel pipe fulcrum block arbitrarily.After respectively two steel pipe fulcrum blocks being fixed, make the end crooked position be positioned at the jacking block position again, providing straightening force to affact by Hydraulic Station to hydraulic cylinder is rectified on the steel pipe, according to the theory of elastic-plastic deformation, the setting of sequencing by action, the function that finish the advancing of hydraulic cylinder, pressurize, retreats reaches the purpose of aligning steel pipe.In whole gag press straightening process, the heavy wall tubing two ends are in free state, and without any axial constraint, so tangible axial tension phenomenon can take place oil pipe.Satisfied the requirement of next procedure car screw thread, it is big to have overcome past artificial pressure straightener labour intensity, and efficient is low, and is of poor quality, the shortcoming that deviation is big, and the present invention has small investment, and is simple to operate, efficient height, characteristics such as flattening precision height.
On two steel pipe fulcrum blocks face relative, semicircle cancave cambered surface is set respectively with jacking block.This purpose of design, meaning:
1, steel pipe should make the relative pressure direction be in same plane in the aligning loading process.In order to prevent the stressed sideslip of steel pipe, adopt semicircle cancave cambered surface can effectively limit moving up and down of steel pipe, the stability when guaranteeing the steel pipe aligning.
2, in principle, because steel pipe is 3 contacts in the aligning loading process.For the some contact position that prevents fulcrum block and jacking block and steel pipe weighs steel pipe wounded, adopt semicircle cancave cambered surface can increase the contact area of fulcrum block and jacking block and steel pipe, the height contact guarantees that for the face contact steel pipe is not weighed wounded.
3, in the equipment making installation process, as long as three maximum weighted lines that three semicircle cancave cambered surfaces that will stand up contact with steel pipe are in the same plane, then steel pipe be subjected to rectify be in stressed the time will automatic capturing to same horizontal plane.
Adjust two steel pipe fulcrum blocks for convenience, the present invention is fixedly connected transition block on base, on transition block, offer the elongated slot parallel with the base length direction, disposed inboard steel pipe fulcrum block in transition block, the fixedly connected bolt in the outside of steel pipe fulcrum block, described bolt is connected with elongated slot by nut.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is that the left side of Fig. 1 is to view.
Fig. 3 bows to view for Fig. 1's.
The specific embodiment
As shown in Figure 1, 2, 3, on a rectangle base 1, arrange two groups of carrying rollers 2,3 along its length.
Along the homonymy of base 1 length direction two steel pipe fulcrum blocks 4,5 that can slide along base 1 length direction are set respectively, are provided with semicircle cancave cambered surface in the one side of each steel pipe fulcrum block 4,5.Concrete grammar can be: two transition block 6,7 are fixed in welding on base 1, are opened in the elongated slot 8,9 on the same horizontal line on two transition block 6,7 respectively, and each elongated slot 8,9 is all parallel with base 1 length direction.Steel pipe fulcrum block 4,5 is arranged in the inboard of corresponding transition block 6,7, the back fixation connecting bolt of the semicircle cancave cambered surface of steel pipe fulcrum block 4,5, and bolt is connected with elongated slot 8,9 by corresponding nut.Unclamp nut, each steel pipe fulcrum block 4,5 is slided in corresponding elongated slot 8,9, screw nut, can determine each steel pipe fulcrum block 4,5 position on base 1.
The opposite side of the base 1 relative with steel pipe fulcrum block 4,5 arrange with steel pipe fulcrum block 4,5 at conplane jacking block 10, the one side of jacking block 10 also is provided with semicircle cancave cambered surface.The hydraulic cylinder 11 of a fixedly connected horizontally set on base 1, fixedly connected with jacking block 10 in the expansion link outer end of hydraulic cylinder 11, and make the semicircle cancave cambered surface of jacking block 10 relative with the semicircle cancave cambered surface of steel pipe fulcrum block 4,5, simultaneously, the central axis of three semicircle cancave cambered surfaces at grade.
