Abstract

The invention discloses a shock absorption method with an equipment base made of foamed aluminum. According to the main technical scheme, a foamed aluminum plate of the specific characteristic and size is used for replacing a traditional wood or cement base and used as a base of common equipment, such as a machine tool, for shock absorption. According to the method, the shock absorption and sound insulation effect is good, and the size is stable after long-time use.

Description

A kind of method using foamed aluminium to do plant bottom case damping
Technical field:
[0001] the present invention relates to a kind of method using foamed aluminium to do plant bottom case damping, belong to industry equipment field.
Background technique:
[0002] foamed aluminium, add additive in pure aluminum or aluminum alloy after, forms through foam process, has metal and bubble feature concurrently simultaneously.Its density is little, high-selenium corn impact capacity is strong, high temperature resistant, fireproof performance is strong, anticorrosive, sound insulation and noise reduction, heat conductivity are low, electromagnetic wave shielding is high, weatherability is strong, have filter capacity, easily processing, easily install, forming accuracy high.
[0003] foamed aluminium has high-damping shock stability and impact energy absorb rate: damping capacity is 5-10 times of metallic aluminium.Porosity ratio is the foamed aluminium of 84% when there is 50% modification, Absorbable rod 2.5mJ/m 3above energy.There is good acoustic function: 1, sound insulation property (closed pore): time on frequency of sound wave between 800-4000Hz, the acoustical reduction coefficient of closed-cell aluminum foam reaches more than 0.9.2, sound absorbing capabilities (micro through hole and through hole): when frequency of sound wave is between 125---4000HZ, the acoustic absorptivity of fine-crystal spume aluminium alloy is maximum reaches 0.8, and its octave average sound absorption coefficient is more than 0.4.
[0004] current, the equipment of most of factory, as lathe, its base damping many employings plank or cement base, high-end devices adopts special vibration damper.Although plank has certain damping effect, dimensional accuracy is not high, and can deform because of pressurized, make moist etc. after permanent use, affects equipment precision.Although cement base intensity is high, good endurance, damping effect is not good.And the Special shock absorber that high-end devices adopts, with high costs, be difficult to promote.
Summary of the invention:
[0005] the present invention is a kind of method using foamed aluminium to do plant bottom case damping, and its mount scheme is: between plant bottom case and concrete floor, place specific foam aluminium plate, as damping and the sound insulation of equipment.Concrete floor punches and installs swell fixture, and foamed aluminium punches, and finally plant bottom case, foamed aluminium and concrete floor is fixed with screw-nut.
[0006] foam aluminium plate that method adopts is the closed-cell aluminum foam that foam melt method or powder metallurgic method produce.Foam aluminium plate used, its porosity ratio is 60 ~ 90%, and density is 0.3 ~ 1 × 10 3kg/m 3, compressive strength is 16 ~ 24MPa, and thermal expansion coefficient is (14 ~ 19) × 10 -6/ ° C.
[0007] required foam aluminium plate thickness is 1 ~ 5 centimetre, and needed for single-base, foamed aluminium areal calculation formula is as follows: area (m 2)=65000 × lathe weight (ton) ÷ base area (cm 2) ÷ base number (if foam density is large, intensity height then gets 0.2).
[0008] when base area is less than required foamed aluminium area, the iron plate that cushioning 5 ~ 10mm is thick, is used as dispersion pressure.
Beneficial effect:
[0009] current, the equipment of most of factory, as lathe, its base damping many employings plank or cement base, high-end devices adopts special vibration damper.Although plank has certain damping effect, dimensional accuracy is not high, and can deform because of pressurized, make moist etc. after permanent use, affects equipment precision.Although cement base intensity is high, good endurance, damping effect is not good.And the Special shock absorber that high-end devices adopts, with high costs, be difficult to promote.The employing foam aluminium plate that the present invention proposes does the method for plant bottom case damping, overcome above shortcoming, good and durable damping performance is achieved with lower cost, and possess good sound absorption qualities, making the vibrations of equipment and noise be unlikely to be transmitted on ground, is a kind of promising standard equipment base shock-dampening method.
Accompanying drawing illustrates:
[0010] Fig. 1 is the schematic diagram that foam aluminium plate is used as base damping.
[0011] reference character: 1-lathe base; 2-attachment screw; 3-foamed aluminium; 4-ground.
Embodiment:
[0012] composition graphs 1 Benq is in a kind of preferred version adopting foam aluminium plate to be used as base damping mentioned by content of the present invention.
[0013] adopt the foam aluminium plate of porosity ratio 80%, thickness 3cm, compressive strength is about 16 ~ 18MPa, and thermal expansion coefficient is (14 ~ 16) × 10 -6/ ° C.
[0014] heavily about 2 tons, lathe, 6 bases, each base area is 100 cm 2left and right.According to formulae discovery, each foamed aluminium beam needs 200 cm 2left and right.
