Abstract
A forging hammer shock absorber is a disc shock absorber. A columnar spring, damping liquid, a mandrel, an upper cover and other accessories are mounted on a circular dish-shaped base to jointly form the disc shock absorber, supporting and shock absorbing functions of the columnar spring are made full use of and organically combined with the damping function of viscous damping agents, and shock absorbing and noise reduction functions for a forging hammer are brought into full play.
Description
Affiliated technical field
The utility model relates to a kind of vibration damper, is mainly used in and eliminates vibration and the noise that forging hammer produces in operating process.
Background technique
Forging hammer, in operating process, can produce strong vibration and noise, and the working environment to equipment, factory building and worker around, causes great harm.Up to now, the method that vibration damping is used, is to adopt between hammer anvil and basis the materials such as cushioning vibration isolation sleeper, rubber, felt substantially, and effectiveness in vibration suppression is very undesirable.Also have devices such as using spring to carry out vibration damping processing, but due to manufacture and installation difficulty large, cost is high, so far not yet can spread.
Summary of the invention
A kind of forging hammer vibration damper, column spring is installed on base, damp liquid, mandrel, by upper cover sealing, limited, it is characterized in that: base (1) is the supporting of whole vibration damper, also form damping cavity and spring lower seat simultaneously, spring (2) is arranged on spring lower seat, and be evenly distributed in damping cavity, mandrel (4) is installed and is limited in damping cavity, and spring (2) is positioned and pretension, on mandrel, be provided with damping hole (6), mandrel (4) can be in damping cavity, by preset stroke, move up and down, upper cover (9) connects sealing with base (1), form an airtight inner chamber, in chamber, by damp liquid, all filled, during installation, vibration damper (13) and positioning ring (12) are arranged on to Supporting Steel Plate (11) above, last, anvil (14) under forging hammer is installed.
The utility model solves the technological scheme that its technical problem adopts:
The gravity of hammer anvil is acted on column spring by mandrel, utilize the compressed supporting force of column spring to support the weight of hammer anvil, make it reach a relative balance state, when hammer anvil is subject to impact force, mandrel is up-down vibration thereupon, but mandrel is subject to again the damping function of viscous damping agent, thereby reach the object of vibration damping.
The beneficial effects of the utility model are, take full advantage of supporting, the vibration-damping function of column spring, simultaneously, again the damping function of it and viscous damping agent, the two organically combines, brought into play to greatest extent they vibration damping, subtract noise contributions, and eliminated vibration.Reduced cost simultaneously, can producing in serial form, be convenient to spread.

Embodiment
In Fig. 1, base (1) is the supporting of whole vibration damper, forms damping cavity and spring lower seat simultaneously.Spring (2) (8) be arranged on spring lower seat, be evenly distributed in damping cavity, mandrel (4) is vertically mounted in damping cavity, and spring (2) is positioned and pretension, upper cover (9) connects sealing with base (1), form an airtight inner chamber, in chamber, fill with damp liquid (8), if External Force Acting is in mandrel (4) upper-end surface, when external force P surpasses initial tension of spring, mandrel (4) can move down by preset stroke in damp liquid (8), and damp liquid just can be extruded to by damping hole (6) top of mandrel (4); When external force P is less than initial tension of spring, mandrel (4) can upwards set back again under acting force of the spring, and at this moment damp liquid can be back to along damping hole (6) below of mandrel (4) again.The effect of seal ring (3) is sealing mandrel two ends.
In this embodiment, the pretightening force of cluster spring, is exactly the nominal load of this vibration damper.
In concrete application process, according to the needs of different tonnage forging hammers, can select the vibration damper of corresponding nominal load, and calculate required quantity, then carry out different combinations and arrange, be arranged between hammer anvil and basis.Formula is:
Anvil weight=separate unit vibration damper nominal load * vibration damper number of units under forging hammer
Installation method is as follows:
According to the size of foundation of forging hammers, select suitable Supporting Steel Plate (11), according to arrangement requirement, arrange positioning ring, check position errorless after, positioning ring (12) and Supporting Steel Plate (11) are welded and fixed, then vibration damper (13) is placed in positioning ring (12) one by one, finally lay anvil under forging hammer (14), lay after lower anvil, by lower anvil surrounding location.
Claims (1)
1. a forging hammer vibration damper, column spring is installed on base, damp liquid, mandrel, by upper cover sealing, limited, it is characterized in that: base (1) is the supporting of whole vibration damper, also form damping cavity and spring lower seat simultaneously, spring (2) is arranged on spring lower seat, and be evenly distributed in damping cavity, mandrel (4) is installed and is limited in damping cavity, and spring (2) is positioned and pretension, on mandrel, be provided with damping hole (6), mandrel (4) can be in damping cavity, by preset stroke, move up and down, upper cover (9) connects sealing with base (1), form an airtight inner chamber, in chamber, by damp liquid, all filled, during installation, vibration damper (13) and positioning ring (12) are arranged on to Supporting Steel Plate (11) above, last, anvil (14) under forging hammer is installed.
