Abstract
The invention relates to an oil press for lamination compaction. The oil press for the lamination compaction comprises a workbench with a through hole in the center, a left stand column, a right stand column and cross beams mounted between the stand columns, wherein the left stand column and the right stand column are mounted on the two sides of the workbench, oil cylinders are arranged on the cross beams, the number of the cross beams is two, the cross beams comprise the front cross beam and the rear cross beam, one end of the front cross beam and one end of the rear cross beam are rotatably fixed on the stand columns through pin shafts, and the other end of the front cross beam and the other end of the rear cross beam are movably fixed on the stand columns. According to the oil press for the lamination compaction, the structure that the front cross beam and the rear cross beam are opened and closed around the pin shafts is adopted, the problem that compaction cannot be carried out on spindles with the length larger than the height of the stand columns due to the fact that the stand columns of a traditional oil hydraulic cylinder are fixed is solved, and the adaptability of the oil press is improved.
Description
Technical field
The present invention relates to hydraulic press, the hydraulic press compressing in particular for lamination.
Background technology
The required stator core of motor is formed by the stator lasmination closed assembly of punching, but stator lasmination needs compress and carry out shaping through hydraulic press before packing motor into.In order to guarantee that the stator after compacting compresses and guarantee vertically, conventionally stator lasmination to be set on a mandrel, then suppresses by hydraulic press pressure head.
But pressure head and the distance between workbench that existing hydraulic press maximum open height is arranged on hydraulic jack are fixing, cannot regulate, and when lamination thickness is larger, while making mandrel length longer, cause hydraulic press cannot effectively press-fit again.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic press compressing for lamination.
The object of the invention is to complete by following technical solution, the hydraulic press compressing for lamination, comprise that there is the workbench of through hole at center, the left column and the right column that are arranged on workbench both sides, be arranged on the crossbeam between column, and crossbeam is provided with oil cylinder, it is characterized in that: described crossbeam has two, be respectively front beam and rear cross beam, described front beam, rear cross beam one end are rotated and are fixed on column by bearing pin, and the other end is movably fixed on column.
The present invention adopts two beam structures, between front beam, rear cross beam, form gap, and crossbeam one end is rotationally connected by bearing pin and column, the other end is flexibly connected, crossbeam can folding on column like this, so when running into mandrel when longer, can open crossbeam, the mandrel that lamination is housed is moved on workbench, just can cannot not realize because of the level altitude of oil hydraulic cylinder, then crossbeam be rotated to return and column is fixed, can compress operation, after completing, crossbeam is rotated and facilitates mandrel to shift out.
Accompanying drawing explanation
Fig. 1 is that the present invention compresses the structural representation of work to the mandrel of lamination is housed;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the present invention is done to detailed introduction:
As Fig. 1, shown in 2: the hydraulic press compressing for lamination, comprise that there is the workbench 2 of through hole 1 at center, this through hole facilitates mandrel to place, be arranged on left column 3 and the right column 4 of workbench both sides, be arranged on the crossbeam between column, crossbeam is provided with oil cylinder 5, concrete described crossbeam has two, be respectively front beam 6 and rear cross beam 7, front beam, rear cross beam right-hand member is rotated and is fixed on column by bearing pin 11, left end is movably fixed on column, front beam, rear cross beam is arranged with respectively two oil cylinders, and front beam, the piston rod head of a pair of oil cylinder of installing on rear cross beam is provided with box pressure head 8.Described bearing pin is fixed on right column by axle end baffle plate 9, and between crossbeam and axle end baffle plate, be provided with plane bearing 10, described crossbeam movable end is fixed with a montant, the position that described column is corresponding with montant is provided with the retainer ring socket-connecting, montant is nested with in retainer ring and just crossbeam and column can be fixed, and facilitates oil cylinder work.
Before and after the present invention adopts, two crossbeams, around bearing pin opening and closing structure, effectively solve traditional oils cylinder pressure column and fix, and cannot be greater than the situation that column height mandrel is suppressed to length, have improved the applicability of hydraulic press.And four cylinder structures that adopt, maximum can reach 200 tons of pressure, and the pressure distribution of compacting lamination is more even, makes pressing result better.
Simultaneously the present invention also can be used in press-fiting of rotor, equally press-fiting applicable to the rotor of wider length.
