Abstract
A four-side pressure straightening mechanism comprises a main frame formed by an upper cross beam, a lower cross beam, a left vertical beam, a right vertical beam, an upright post and anvil blocks; four master cylinders are symmetrically arranged on the main frame; one upper master cylinder is mounted on the upper cross beam; one lower master cylinder is mounted on the lower cross beam; two horizontal master cylinders are respectively mounted on the left vertical beam and the right vertical beam; in the straightening process, firstly the space between the anvil blocks is determined according to the state of a workpiece before straightening, quick straightening in the four directions can be realized, and the condition that when the upper hydraulic master cylinder is under reacting force, the reacting force can be borne by the prestressed main frame can be ensured. The four-side pressure straightening mechanism does not need to overturn the workpiece, improves the straightening efficiency, improves the efficiency of a finishing line at the rear part of a whole profiled bar, and optimizes the manufacture process of the profiled bar.
Description
Technical field
The utility model relates to the straightener for special sections such as square steel and rail, particularly a kind of four sides gag press structure.
Background technology
Existing market is more and more higher for the requirement of the condition of delivery of the special sections such as square steel and rail, and its existing rolling mill practice cannot guarantee that the workpiece of roll forming can reach the standard of direct delivery completely, derived the relevant device of many profile shapes finishing, and gag straightener is exactly wherein a kind of at this point.Gag straightener can be divided into horizontal and vertical two kinds according to the movement locus of master cylinder, once align after operation completing, these two kinds of form straighteners all need by turnover workpiece turning to another bending curve position, just caused the operating efficiency of gag straightener integral body low, if equipment on-line is arranged, will seriously restrict the efficiency of finishing line.So mostly existing gag straightener is off-line, arrange, and off-line layout lifts the problem of overlong time after rectifying before will causing workpiece to rectify.And novel four sides gag straightener can be aligned from four direction, without upset workpiece, saved the overall work time, improve aligning efficiency.The column that is connected that simultaneously utilizes compression crossbeam and vertical beam, makes whole framework form a prestressed stand, has improved the rigidity of frame and the stability of the process of aligning, can significantly improve the monolithic stability of frame.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of four sides gag press structure, without upset workpiece, improves aligning efficiency, improves the efficiency of whole piece profile shapes rear portion finishing line, improves the process optimization that profile shapes is produced.
In order to achieve the above object, the technical scheme that the utility model adopts is achieved in that
A kind of four sides gag press structure, comprise the mainframe that a vertical beam 1 by entablature 2, sill 9, left and right, column 4 and anvil block 6 form, entablature 2 and sill 9 are welding structural element and column 4 welding, column 4 is strained and fixed by locking nut 5 with vertical beam 1, anvil block 6 is slidably connected with the slide rail face of entablature 2 and sill 9, on mainframe, be provided with four master cylinders in a symmetrical arrangement, a upper master cylinder 3 is arranged on entablature 2, a lower master cylinder 8 is arranged on sill 9, and two horizontal master cylinders 7 are arranged on respectively on two vertical beams 1 in left and right.
The utility model vertical beam and lower and upper cross-member have seam to fix, for four direction simultaneously stuck, lower and upper cross-member and left and right vertical beam is fixing as a whole, when on guaranteeing in aligning process, hydraulic main cylinder bears reaction force, can be born by Whole Equipment, utilize the frame of prestressing force form, form one without turning over steel, can carry out the novel pressure straightener of aligning fast at four direction.
Accompanying drawing explanation
Accompanying drawing is structure principle chart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in detail.
With reference to accompanying drawing, a kind of four sides gag press structure, comprise the mainframe that the anvil block 6 at a vertical beam 1 by entablature 2, sill 9, left and right, column 4 and middle part forms, entablature 2 and sill 9 are welding structural element and column 4 welding, column 4 is strained and fixed by locking nut 5 with vertical beam 1, thereby form prestressing force mainframe, guarantee the stability of Whole Equipment, column 4 need to adopt pressure device to be stretched when installing first, tensile force is about 1.5 times of equipment straightener, and the tight locking nut 5 of standby; Anvil block 6 is slidably connected with the slide rail face of entablature 2 and sill 9; On mainframe, be provided with 4 master cylinders in a symmetrical arrangement, a upper master cylinder 3 is arranged on entablature 2, and a lower master cylinder 8 is arranged on sill 9, and two horizontal master cylinders 7 are arranged on respectively on two vertical beams 1 in left and right.
Operation principle of the present utility model is: in aligning process, first need to determine according to the strong front state of being rectified workpiece the spacing of anvil block 6, anvil block 6 can move along the slide rail face of entablature 2 and sill 9, its inside is provided with bearing, removable for series, can select according to workpiece shape difference.Totally 4 of master cylinders, are 3 one of upper master cylinders, 8 one of lower master cylinders, and 7 two of horizontal master cylinders, are arranged on respectively in entablature 2, sill 9 and vertical beam 1, in a symmetrical arrangement.The Position Control of master cylinder is detected by built-in linear displacement transducer, and oil cylinder stroke is controlled predeterminable.Four master cylinders are provided with F.F., work is entered and backward mode, and cylinder head moves in front of workpiece with F.F. form, and then work is entered to align, align complete, the quick rollback of cylinder bar.Pressure is furnished with front and back roller-way before and after rectifying, after a locus aligning, can open roller-way travelling workpiece forward or backward, repeats to align operation, until whole workpiece is qualified.
