Abstract
A forging hammer damping and sound isolating device comprises a sound isolating bin which is arranged below a hammer. Wooden block groups are arranged inside the sound isolating bin and at the lower end of the hammer. A large foundation is arranged below the wooden block groups. Spring groups are arranged on four corners below the large foundation and in the middle of each side of the large foundation. According to the forging hammer damping and sound isolating device, damping is achieved mainly through the spring groups and the wooden block groups, the sound isolating bin is added for sound isolating, so that the forging hammer damping and sound isolating device has the advantages of being simple in equipment, low in cost, good in stability, obvious in damping and sound isolating effect, free of oscillation, convenient to mount and maintain and particularly suitable for impact oscillation equipment of middle-small tonnages.
Description
Technical field
The utility model relates to the forging machinery technical field, particularly the damping of middle-size and small-size forging hammer hammer down and sound arrester.
Background technology
Domestic existing metal forming machinery mainly is made of critical pieces such as fuselage, compression piston, transmission, hammer stem helical pitch, hammer stem, anvil block and manipulations.Operation principle is as follows: utilize hydraulic gear to make and fall part (piston, hammer stem, tup, upper anvil (or upper module) generation motion and accumulation kinetic energy, impose on forging in the extremely short time, make it on flat anvil, to obtain plastic deformation ability, finish various Forging Technologies.Because forging hammer is that vibration is than macrospecies equipment, oscillatory acceleration for reduction and its amplitude of vibration of setback, domestic and international existing forging hammer adopts mass foundation mostly, all use pouring concrete, this basis is heavy, the consumption of material is more, forging hammer with very large anvil block or movable lower ram as the bearing-surface that hits, when impulse stroke, blow speed moment of tup is down to zero, and work is impact, produce very large hitting power, not only have a strong impact on precision instrument on every side, equipment normally moves, and reduces stability and the service life thereof of factory building structure, and is a kind of industrial nuisance that is detrimental to health.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this utility model is to provide the damping of forging hammer hammer down and sound arrester, it is simple to have equipment, with low cost, have good stability, the damping soundproof effect is outstanding, dead-beat, be convenient to installation and maintenance, and be specially adapted to the advantage of medium and small tonnage shock oscillation equipment.
In order to achieve the above object, technical scheme of the present invention is achieved in that
The damping of forging hammer hammer down and sound arrester, comprise the sound insulation storehouse 3 that is arranged on hammer down 7 belows, lower end at 3 inside, sound insulation storehouse and hammer down 7 is provided with wooden unit group 2, and the below of wooden unit group 2 is large basis 4, and four jiaos of large basic 4 belows and each centre position, limit are provided with groups of springs 1.
This practical new technology mainly adopts groups of springs 1 and 2 dampings of wooden unit group, and increases sound insulation storehouse 3, and it is simple to make it have equipment, with low cost, have good stability, the damping soundproof effect is outstanding, dead-beat is convenient to installation and maintenance, and is specially adapted to the advantage of medium and small tonnage shock oscillation equipment.
Description of drawings
Accompanying drawing is the structural representation under the utility model use state.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are done and to be described in detail.
With reference to accompanying drawing, the damping of forging hammer hammer down and sound arrester, comprise the sound insulation storehouse 3 that is arranged on hammer down 7 belows, lower end at 3 inside, sound insulation storehouse and hammer down 7 is provided with wooden unit group 2, the below of wooden unit group 2 is large basis 4, four jiaos of large basic 4 belows and each centre position, limit are provided with groups of springs 1, groups of springs 1 usefulness bolt directly be fixed on large basic 4 and ground on, all groups of springs 1 distortion are all the same.
Operation principle of the present utility model is:
Transmission mechanism makes and falls part (piston, hammer stem, tup, upper anvil (or upper module), produce motion and accumulation kinetic energy, impose on forging in the extremely short time, make it to obtain plastic deformation ability, finish various Forging Technologies, in this process, tup 6 on the support 5 knocks on hammer down 7, kinetic energy is passed to large basic 4, and use wooden unit group 2 avoids support that large basis is directly impacted between large basis 4 and the support 5, kinetic energy in good 1 the impact-absorbing process of groups of springs of absorbing performance, and 3 offset the part noises in the sound insulation storehouse, to reach the effect of damping sound insulation, large basis 4 utilizes shock-resistant, antifatigue, the life-span is long.
More as can be known, the damping property of this device is better by this device and traditional vibration insulating foundation, can reduce forging hammer to the vibration of surrounding environment more than 80%.Improved to a great extent workman's operating environment, make production can carry out smoothly one surely degree obtained guarantee.
