Abstract

The invention discloses a forming machine damping device. At present, a rubber pad or a V and X type rubber shaping material are generally adopted to be mounted between materials of a damping mechanism for playing a damping role, and although such mechanism has the advantages of being simple in structure and convenient to use, the service life of the rubber material is very short as a nominal pressure of a forging machine is generally high and the generated vibration is great. According to the invention, an energy accumulator is adopted for absorbing vibration, so that long service life is achieved; furthermore, a spring also can be added on a damping oil cylinder to play a dual-damping role, so that better damping effect is obtained, and better safety is achieved.

Description

Forging press damping device
Technical field
The present invention relates to a kind of 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 this kind of mechanism has structure simply, advantage easy to use, can only be general larger due to forging press nominal pressure, the vibration produced is large, and elastomeric material is very short for service life.
Summary of the invention
Goal of the invention: the object of this invention is to provide that a kind of structure is simple, the forging press damping device of long service life.
Technical scheme: a kind of forging press damping device, comprises oil cylinder, accumulator, overflow valve, and described oil cylinder is connected by pipeline with described accumulator, and described pipeline is provided with overflow valve.
Like this when piston rod or the cylinder barrel pressurized of described oil cylinder, the oil of described oil cylinder is pressed into described accumulation of energy wherein, thus plays cushioning effect, and described overflow valve shields.
Also stop valve can be provided with, to be convenient for changing accumulator between described oil cylinder and described accumulator.
In order to play better damping effect, preferably the rodless cavity of described oil cylinder is connected with described accumulator.
The rod chamber of described oil cylinder also can be provided with spring, and owing to there being the existence of spring, it is used that described spring also can play damping, dual shock absorption better effects if, even if fluid damping is broken down, spring can also play cushioning effect, also can reduce the impact of vibration to fluid shock mitigation system simultaneously.
Equally, the rodless cavity of described oil cylinder also can be provided with spring.
Beneficial effect: damping device of the present invention, the life-span, comparatively General Purpose Rubber damping device was long, and damping effect, in addition, adjusts the pressure of described overflow valve, and the pressure of described accumulator, can also play different damping effects, meet the demand of different forging press.
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 forging press damping device, comprises oil cylinder 1, accumulator 2, overflow valve 3, it is characterized in that: described oil cylinder 1 is connected by pipeline with described accumulator 2, described pipeline is provided with overflow valve 3.
Stop valve 4 is also provided with between described oil cylinder 1 and described accumulator 2.
The rodless cavity of described oil cylinder 1 is connected with described accumulator 2.
The rod chamber of described oil cylinder 1 is also provided with spring 5.
The rodless cavity of described oil cylinder 1 is provided with spring 6.
Like this when piston rod or the cylinder barrel pressurized of described oil cylinder, the oil of described oil cylinder is pressed into described accumulation of energy wherein, thus plays cushioning effect, and described overflow valve shields.
When needing to change accumulator, described stop valve can be closed.
Adjust the pressure of described overflow valve, and the pressure of described accumulator, different damping effects can also be played, thus meet the demand of different forging press.
Owing to there being the existence of spring, it is used that described spring also can play damping, dual shock absorption better effects if, even and if fluid damping break down, spring can also play cushioning effect, also can reduce the impact of vibration to fluid shock mitigation system simultaneously.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
