Abstract
The invention discloses a shock-absorbing device of a forging press, at present, a rubber cushion or V, X type rubber shaping material is generally adopted to be arranged between materials of a shock-absorbing mechanism for shock-absorbing application, the mechanism has the advantages of simple structure and convenient use, but the mechanism can only generate large vibration and has short service life of the rubber material because the nominal pressure of the forging press is generally larger; the invention adopts the energy accumulator to absorb the vibration, has long service life, can also add a spring on the damping oil cylinder to play a role of double damping, has better damping effect and is safer.
Description
Technical Field
The invention relates to a damping device, in particular to a damping device of a forging press, and belongs to the technical field of forging presses.
Background
At present, the damping device used on the forging machine tool generally adopts a rubber cushion or V, X type rubber shaping material arranged between the materials of the damping mechanism for damping application, and the mechanism has the advantages of simple structure and convenient use, but can only generate large vibration and have short service life of the rubber material because the nominal pressure of a forging press is generally larger.
Disclosure of Invention
The purpose of the invention is as follows: the invention aims to provide a shock absorption device of a forging press, which has a simple structure and a long service life.
The technical scheme is as follows: the shock absorption device of the forging press comprises an oil cylinder, an energy accumulator and an overflow valve, wherein the oil cylinder is communicated with the energy accumulator through a pipeline, and the overflow valve is arranged on the pipeline.
Therefore, when a piston rod or a cylinder barrel of the oil cylinder is pressed, oil of the oil cylinder is pressed into the energy storage tank, so that the shock absorption effect is achieved, and the overflow valve plays a protection effect.
A stop valve can be arranged between the oil cylinder and the energy accumulator to facilitate the replacement of the energy accumulator.
In order to achieve better shock absorption effect, it is preferable that the rodless cavity of the oil cylinder is communicated with the accumulator.
The rod chamber of hydro-cylinder still can be provided with the spring, owing to there is the existence of spring, the spring also can play the shock attenuation used, and dual shock attenuation effect is better, even the fluid shock attenuation breaks down moreover, the spring can also play the cushioning effect, still can reduce the impact of vibration to fluid shock mitigation system simultaneously.
Likewise, the rodless chamber of the cylinder may also be provided with a spring.
Has the advantages that: the damping device has longer service life than the common rubber damping device and good damping effect, and in addition, different damping effects can be achieved by adjusting the pressure of the overflow valve and the pressure of the energy accumulator, so that the requirements of different forging machines are met.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present invention.
Detailed Description
As shown in the figure, the shock absorption device of the forging press comprises an oil cylinder 1, an energy accumulator 2 and an overflow valve 3, and is characterized in that: the oil cylinder 1 is communicated with the energy accumulator 2 through a pipeline, and an overflow valve 3 is arranged on the pipeline.
And a stop valve 4 is also arranged between the oil cylinder 1 and the energy accumulator 2.
And a rodless cavity of the oil cylinder 1 is communicated with the energy accumulator 2.
And a spring 5 is also arranged in a rod cavity of the oil cylinder 1.
And a spring 6 is arranged in a rodless cavity of the oil cylinder 1.
Therefore, when a piston rod or a cylinder barrel of the oil cylinder is pressed, oil of the oil cylinder is pressed into the energy storage tank, so that the shock absorption effect is achieved, and the overflow valve plays a protection effect.
The shut-off valve may be closed when the accumulator needs to be replaced.
The pressure of the overflow valve and the pressure of the energy accumulator are adjusted, so that different damping effects can be achieved, and the requirements of different forging presses are met.
Because there is the spring, the spring also can play the shock attenuation used, and dual shock attenuation effect is better, even the fluid shock attenuation breaks down moreover, the spring can also play the cushioning effect, still can reduce the impact of vibration to fluid shock mitigation system simultaneously.
In addition to the above embodiments, the present invention may have other embodiments, and any technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of the claims of the present invention.
