Abstract
The invention discloses a shock absorber of a forging hammer. A columnar spring, damping liquid, a mandrel, an upper cover and other accessories are mounted on a circular container type base to form a disc type shock absorber; and the shock absorber fully uses the functions of support and shock absorption of the columnar spring, and organically combines the functions with the damping function of a viscous damping agent to fully exert the effects of shock absorption and noise reduction on the forging hammer.
Description
Technical field
The present invention relates to a kind of shock absorber, be mainly used in the vibration & noise eliminated forging hammer and produce in operation.
Background technology
Forging hammer in operation, can produce strong vibration & noise, to the working environment of the equipment of surrounding, factory building and worker, causes great harm.Up to now, the method that vibration damping uses, be adopt the material such as cushioning vibration isolation sleeper, rubber, felt between hammer anvil and basis substantially, effectiveness in vibration suppression is very undesirable.Also have and use the device such as spring to carry out vibration damping process, but due to manufacture and installation difficulty greatly, cost is high, so far not yet can spread.
Summary of the invention
In order to obtain efficient effectiveness in vibration suppression, reducing manufacturing cost again simultaneously, simplifying mounting process, be beneficial to large scale application, the invention provides a kind of viscous damping forging hammer shock absorber.Solve the problems referred to above that prior art exists well.
The technical solution adopted for the present invention to solve the technical problems is:
The gravity of hammer anvil is acted on column spring by mandrel, utilize column spring by the supporting force compressed to support the weight of hammer anvil, it is made to reach a relative balance state, when hammer anvil is subject to impulsive force, mandrel incites somebody to action up-down vibration thereupon, but mandrel is subject to again the damping action of viscous damping agent, thus reach the object of vibration damping.
The invention has the beneficial effects as follows, take full advantage of the supporting of column spring, vibration-damping function, simultaneously again the damping function of it and viscous damping agent, the two organically combines, play their vibration damping to greatest extent, subtracted noise contributions, and eliminate vibration.Reduce cost simultaneously, can producing in serial form, be convenient to spread.
Below in conjunction with drawings and Examples, the present invention will be further described.

In Fig. 3: 11, supporting steel plate, 12, locating ring, 13, shock absorber, 14, anvil under forging hammer.
Detailed description of the invention
In FIG, base (1) is the supporting of whole shock absorber, forms damping cavity and spring lower seat simultaneously.Spring (2) (8) is 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 with base (1) and seals, form an airtight inner chamber, damping fluid (8) is filled in chamber, if External Force Acting is in mandrel (4) upper surface, when external force P exceedes initial tension of spring, mandrel (4) can move down by preset stroke in damping fluid (8), and damping fluid just can be extruded to the top of mandrel (4) by damping hole (6); When external force P is less than initial tension of spring, mandrel (4) can upwards set back again under spring action, and at this moment damping fluid can be back to again the below of mandrel (4) along damping hole (6).The effect of sealing ring (3) is sealing mandrel two ends.
In this embodiment, the pretightning force of groups of springs is exactly the nominal load of this shock absorber.
In embody rule process, according to the needs of different tonnage forging hammer, the shock absorber of corresponding nominal load can be selected, and the quantity needed for calculating, then carry out different combinations and arrange, be arranged between hammer anvil and basis.Computing formula is:
Anvil weight under forging hammer=separate unit shock absorber nominal load × shock absorber number of units
Claims (1)
1. a forging hammer shock absorber, base is installed column spring, damping fluid, mandrel, sealed by upper cover and limit, it is characterized in that: base (1) is the supporting of whole shock absorber, 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, mandrel is provided with damping hole (6), mandrel (4) can in damping cavity, move up and down by preset stroke, upper cover (7) connects with base (1) and seals, form an airtight inner chamber, all filled by damping fluid in chamber.
