Abstract
The invention discloses a hydraulic damping device. Currently, rubber gaskets or V-type and X-type rubber sizing materials are installed among materials of a damping mechanism for damping; although the rubber gaskets or V-type and X-type rubber sizing materials have the advantages of being simple in structure and convenient to use, since a forging press is large in nominal pressure and generated vibration, rubber materials are short in service life; the rubber materials cannot achieve multi-directional damping, and the damping effect is poor. According to the hydraulic damping device, a double-acting double-piston oil cylinder and energy accumulators are used to absorb vibration, and the hydraulic damping device is long in service life, capable of achieving multi-directional all-dimensional damping, better in damping effect, safe, and reliable.
Description
Technical field
The present invention relates to a kind of hydraulic damping device, particularly a kind of forging press damping device, belongs to forging press technical field.
Background technology
At present, be used in the damping device above forging machine tool, that generally adopt is rubber pad or V, X-type rubber shaping material is installed between the material of damping, apply as damping, although it is simple that this kind of mechanism has structure, advantage easy to use, but can only be general larger due to forging press nominal pressure, the vibration produced is large, elastomeric material is very short for service life, in addition also have, other damping device, as some hydraulic damping device, service life is with length, but, the one direction that can only meet forging machine tool uses, for the axis of forging machine tool, radial, Qu Xiang, the damping effect of bending direction is poor.
Summary of the invention
Goal of the invention: the object of this invention is to provide that a kind of structure is simple, long service life, and can multi-direction damping hydraulic damping device.
Technical scheme: a kind of hydraulic damping device, comprise oil cylinder, the first accumulator, the second accumulator, described oil cylinder is double acting double rod cylinder, and the first chamber of described oil cylinder is connected with described first accumulator, and the second chamber of described oil cylinder is connected with described second accumulator.
In order to ensure that system is safer, between the first chamber of described oil cylinder and described first accumulator, be provided with the first overflow valve.
Equally, the second overflow valve is provided with between the second chamber of described oil cylinder and described second accumulator.
Can also stop valve be provided with between described first chamber and described first accumulator and between described second chamber and described second accumulator, can Hydraulic Elements be convenient for changing like this.
The setting pressure of described first accumulator, described second accumulator can be different, and its pressure can be determined according to the magnitude of vibrations of different directions, thus make overall vibration reach minimum.
In like manner, the setting pressure of described first overflow valve, described second overflow valve also can be different.
Described first chamber and or described second chamber in be provided with spring, spring can reduce to vibrate impact to hydraulic system, and can play the effect of dual fail-safe, even if hydraulic system is out of order, damping effect still exists.
Beneficial effect: damping device of the present invention, the life-span, comparatively General Purpose Rubber damping device was long, damping effect, and can realize the damping effect of all directions.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Detailed description of the invention
As shown in the figure, a kind of hydraulic damping device, comprise oil cylinder 1, first accumulator 2 and the second accumulator 3, described oil cylinder 1 is double acting double rod cylinder, first chamber 11 of described oil cylinder 1 is connected with described first accumulator 2, second chamber 12 of described oil cylinder 1 is connected with described second accumulator 3, be provided with the first overflow valve (4) between first chamber 11 of described oil cylinder 1 and described first accumulator 2, between the second chamber 12 of described oil cylinder 1 and described second accumulator 3, be provided with the second overflow valve (5).
Stop valve 6 is provided with between described first chamber 11 and described first accumulator 2 and between described second chamber 12 and described second accumulator 3.
