Abstract
A straightening machine for prestressed pressure in all directions comprises a main frame composed of upper cross beams, lower cross beams, left and right vertical beams, uprights and anvil blocks. Four main cylinders which are symmetrically arranged are arranged on the main frame, one upper main cylinder is mounted on the upper cross beams, one lower main cylinder is mounted on the lower cross cylinders, and two horizontal main cylinders are respectively mounted on the left and right vertical beams; during straightening, spacing of the anvil blocks can be well determined according to the pre-straightening state of a workpiece to be straightened, the workpiece can be straightened in four directions, the counter-acting force borne by the upper hydraulic main cylinder can be assuredly borne by the prestressed main frame during straightening process, the workpiece does not need to be turned over, straightening efficiency can be improved, efficiency of rear finishing line of a whole profiled bar can be improved, and the process of production of the profiled bar can be optimized.
Description
Technical field
The present invention relates to the straightener for the special section such as square steel and rail, particularly a kind of prestressing force four sides gag press.
Background technology
Existing market is more and more higher for the requirement of the condition of delivery of the special section such as square steel and rail, and its existing rolling mill practice cannot ensure 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 one wherein 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 cause the operating efficiency of gag straightener entirety low, if equipment on-line is arranged, will seriously restrict the efficiency of finishing line.Arrange so mostly existing gag straightener is off-line, 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, save the overall work time, improve aligning efficiency.Utilize the column that is connected of compression crossbeam and vertical beam simultaneously, make whole framework form a prestressed stand, 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 object of the present invention is to provide a kind of prestressing force four sides gag press, without upset workpiece, improve the efficiency of aligning efficiency, raising whole piece profile shapes rear portion finishing line, improve the process optimization that profile shapes is produced.
In order to achieve the above object, the technical solution adopted in the present invention is achieved in that
A kind of prestressing force four sides gag press, 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 welds, 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.
Vertical beam of the present invention and lower and upper cross-member have seam to fix, for four direction simultaneously stuck, by fixing as a whole to lower and upper cross-member and left and right vertical beam, when on ensureing 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.
Brief description of the drawings
Accompanying drawing is structure principle chart of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail.
With reference to accompanying drawing, a kind of prestressing force four sides gag press, 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 welds, column 4 is strained and fixed by locking nut 5 with vertical beam 1, thereby form prestressing force mainframe, ensure the stability of Whole Equipment, column 4 need to adopt pressure device to be stretched in the time 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 invention 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.
