Abstract
The utility model relates to a double-cylinder pull-type special horizontal shaft oil hydraulic press which comprises a pedestal, both ends of the pedestal are respectively provided with a fixed pressing seat and a movable pressing seat, and both sides of the fixed pressing seat are fixedly provided with two high pressure oil tanks. Furthermore, ring-shaped pistons are arranged in the high pressure oil tanks, one end of each ring-shaped piston is connected with an oil hydraulic press pull rod, and the other end of the oil hydraulic press pull rod is connected with the movable pressing seat through nuts. By adopting double-shaft horizontal pull-type press, the utility model enhances the safety of a technical process, the uniformity of the press of a pole core and the product quality, and has simple and reasonable structure and flexible operation. In addition, the utility model can measure the main part of a workpiece and the changing condition of the main part by eye survey during the construction, has convenient operation and raises the work efficiency.
Description
[technical field]
The utility model relates to a kind of pressure apparatus, and especially relating to a kind of is the pull-type horizontal axis oil pressure of the pole core horizontal dual cylinder special plane of power source with hydraulic pressure.
[background technology]
Existing motor pole iron core press-fits pressure apparatus two kinds: a kind of to be core length carry out vertically press-fiting at the vertical four post hydraulic presses of the employing below 1 meter, the type is vertical to press-fit: because the downside pull-rod nut is by pole end-plate and frock sealing, when reaching pressure, iron core can't screw simultaneously with the upside pull-rod nut, after hydraulic press pressure is removed, iron core is resilience to some extent, compaction degree diminishes, be difficult to carry out that small bore, length are big, the pole core press mounting of poor stability, workpiece has the possibility of toppling in the work progress.To be core length carry out horizontally press-fiting at the horizontal twin columns hydraulic press of the employing more than 1 meter another kind.The type is horizontal to press-fit: adopt general horizontal (double action) oil hydraulic, price is expensive, and volume is big, the form of exerting pressure applies top power for the single oil cylinder at the place, axis to workpiece, the centre of form of the iron core of the big length that requirement is pressed overlaps as far as possible with the Center of Pressure, otherwise, can cause pressing back iron core torsion resistance to exceed standard; Equally, if punching is respectively bigger to thickness deviation, can cause pressing iron core both sides, back degree of tightness to differ, form fan and open, the torsion resistance increase influences the iron core quality, easily produces the slide plate phenomenon when not wearing the screw rod first pressing, does not have potential safety hazard.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of pull-type horizontal axis oil pressure of the twin-tub special plane that rationally, can estimate the main position of workpiece and changing condition thereof, handled easily, raising work efficiency advantage when flexible movements, construction simple for structure that has.
The technical scheme that its technical problem that solves the utility model adopts is: the pull-type horizontal axis oil pressure of a kind of twin-tub special plane, comprise base, be separately installed with fixedly wedge and movable wedge at the two ends of base, be installed with two high-voltage oil cylinders in the fixing both sides of wedge, annular piston is housed in high-voltage oil cylinder, one end of annular piston is connected with the hydraulic press pull bar, and the other end of this hydraulic press pull bar is connected with movable wedge by nut.
Be respectively equipped with oil-in and oil return opening on described high-voltage oil cylinder, oil-in and oil return opening link with the hydraulic oil pumping plant respectively by oil pipe.
Be provided with press mounting tool between described fixedly wedge and movable wedge, this press mounting tool is fixed on the base.
The beneficial effects of the utility model are: adopt that double-shaft horizontal is pull-type exerts pressure, improve the security of technical process, the uniformity of pole core pressure, improve the quality of products.Device structure is succinct rationally, flexible movements, can estimate the main position and the changing condition thereof of workpiece during construction, and handled easily improves work efficiency.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-high-voltage oil cylinder, 2-be wedge, 3-hydraulic press pull bar, 4-press mounting tool, 5-pole core, the movable wedge of 6-, 7-nut, 8-base, 9-oil connection, 10-annular piston fixedly.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, the pull-type horizontal axis oil pressure of a kind of twin-tub special plane, comprise base 8, be separately installed with fixedly wedge 2 and movable wedge 3 at the two ends of base 8, be installed with two high-voltage oil cylinders 1 in the fixing both sides of wedge 2, be respectively equipped with oil-in and oil return opening on described high-voltage oil cylinder 1, oil-in and oil return opening link with the hydraulic oil pumping plant respectively by oil connection 9 and oil pipe, by the hydraulic oil pumping plant as pressure source.Annular piston 10 is housed in high-voltage oil cylinder 1, and an end of annular piston 10 is connected with hydraulic press pull bar 3, and the other end of this hydraulic press pull bar 3 is connected with movable wedge 6 by nut 7.Be provided with press mounting tool 4 between described fixedly wedge 2 and movable wedge 6, this press mounting tool 4 is fixed on the base 8.Workpiece is a pole core 5, pole core 5 fixes by press mounting tool 4, during action, the hydraulic oil (maximum pressure is 35Mpa) of oil pump station output injects 1 pair of annular piston 10 of high-voltage oil cylinder by high pressure valve, high-pressure oil pipe and exerts pressure, promote hydraulic press pull bar 3 and in high-voltage oil cylinder 1, do insert action, pulling activity wedge 6 is done compressed action in guide pad, pole core 5 workpiece are exerted pressure.Because the twin shaft twin-tub is pull-type exerts pressure, course of action two ends pulling force autobalance, stability improves.Even each is bigger to thickness deviation in pole core 5 punchings, workpiece has prismatic slightly, also can implement evenly to exert pressure, and guarantees the compaction degree of pole core 5 and the glacing flatness of two sides.Because horizontal exerting pressure, convenient increase and decrease punching can screw pull-rod nut simultaneously at two ends, guaranteed that equipment pressure is removed after, pole core 5 springback capacities are in allowed band.
