Description
Technical field
The utility model relates to a kind of sound insulation and noise reduction equipment, is specifically related to a kind of machine tool outer casing of safety noise reduction.
Background technology
The equipments of industrial product such as lathe are because needs carry out metal processing, the work of the equipment such as motor, cylinder all can produce larger noise, and in workshop, can have a large amount of operating personnel to carry out production operation simultaneously, in order to guarantee preferably to work and production environment, guarantee the healthy of workman, need the efficient noise that reduces the equipment such as lathe.Effective method is exactly for machinery equipment, to load the outer cover of noise reduction, the noise that machine produces is reduced inner elimination of outer cover, thereby guarantee preferably noise level of workshop.
Existing machine tool outer casing all has the shell of metal, also there is the machine tool outer casing of part can adhere in metal shell inside sound insulation and noise reduction material, but, the noise that the machinery equipments such as lathe produce is different from common noise, and decibel and the frequency of its noise are used common acoustic damping materials effectively to abate the noise.And, because the equipment such as lathe need watch window, the circulation that need to carry out air by window is to carry out machine heat radiation, and existing machine tool outer casing is just realized gas communication by simple opening, the noise of machine spreads out of by opening, and working environment is affected greatly.Watch window also just arranges simple common shatter proof glass, can not play preferably decrease of noise functions.
So existing machine tool outer casing can not efficiently reduce noise, observation window and air hole can not efficiently reduce noise, and the working environment of workshop is caused to adverse effect.
Utility model content
The utility model technical issues that need to address are just to overcome the defect of prior art, a kind of machine tool outer casing of safety noise reduction is provided, it can efficiently reduce lathe noise, make the observation window of outer cover and the air hole also can high-efficient noise-reducing, thereby improve the whole anti-acoustic capability of machine tool outer casing, improve the security of observation window and air hole.
For addressing the above problem, the utility model adopts following technical scheme:
The machine tool outer casing of safety noise reduction, comprises cover body, and cover body upper end is provided with the window for ventilative heat radiation, cover body side is provided with for observing the cleaved glass of lathe duty, cleaved glass is triplex glass plate, and than existing common shatter proof glass, its security and anti-acoustic capability are higher; Cover body is sandwich construction, and the outermost layer of cover body is panel, and panel inner side is followed successively by sound panel, acoustical cotton layer and sound-absorbing snail inner panel, and sound panel and acoustical cotton layer can reduce lathe noise to a certain extent; Sound-absorbing snail inner panel is provided with the sound-absorbing snail of taper, and sound-absorbing snail inwall is provided with annular noise reduction circle, and the noise that noise reduction circle can produce lathe carries out efficient absorption; On the inwall of sound-absorbing snail inner panel, with dustproof membrane, dustproof membrane prevents that the dust in lathe from falling into the anti-acoustic capability reduction that makes sound-absorbing snail in sound-absorbing snail; Array shutter is installed on window, in the window frame of array shutter, be provided with some layers of blinds group, every layer of blinds group consists of several parallel blinds that are set up in parallel, the blinds of lower one deck blinds group is arranged at the below between two adjacent blinds of last layer blinds group, alternate like this setting can allow in the smooth and easy inflow outer cover of the air on array shutter top, the noise that the right side can efficient absorption lathe produces.
Noise reduction circle on sound-absorbing snail tilts to sound-absorbing snail outside.Noise reduction circle tilts laterally, noise reflection can be entered in sound-absorbing snail, and in sound-absorbing snail, efficient absorption reduces noise, and the inwall of sound-absorbing snail also consists of acoustical cotton.
The utility model is in order to make the air can smooth and easy inflow cover body, reducing noise spreads out of from window, preferably technical scheme also has, each blinds forms by the left plate of blinds and blinds right panel, the left end of the right-hand member of the left plate of blinds and blinds right panel connects as one, and the left end of the left plate of blinds is downward-sloping, the right-hand member of blinds right panel is downward-sloping.From top leaked-in air, can enter smoothly like this, the noise transmitting from downside need to reflection multilayer and absorption between array blinds, finally realizes the function of noise reduction; The surface of blinds is provided with acoustical cotton.
The utility model is in order further to improve the absorbing sound and lowering noise effect of sound-absorbing snail, and preferably technical scheme also has, and the cross section of noise reduction circle is acute triangle, and the angle of the lateral wall of noise reduction circle and sound-absorbing snail inwall is 70 °～85 °.While avoiding like this right angle or obtuse angle, make in a large amount of noise reflection meeting cover bodies, the fixture of 70 °～85 ° can make the more reflection of noise enter in sound-absorbing snail, thereby reaches better noise reduction.
The utility model is in order further to improve the anti-acoustic capability of sound-absorbing snail, preferably technical scheme also has, sound-absorbing snail inwall is provided with the first noise reduction circle, the second noise reduction circle and the 3rd noise reduction circle, and the first noise reduction circle, the second noise reduction circle and the axis of the 3rd noise reduction circle and the dead in line of sound-absorbing snail.
The utility model is in order to improve the noise reduction of array shutter, and preferably technical scheme also has, and the angle of the left plate of blinds and blinds right panel is 100 °～140 °; Horizontal range in same blinds group between adjacent two blinds is 1/5～1/3 of blinds horizontal width, and the too small meeting of distance makes air flow into resistance to increase, and distance is crossed conference more spreads out of the noise of downside, is unfavorable for reducing noise pollution; Height distance between two adjacent blinds groups is 1.2～2 times of blinds height, and same, height distance is excessive, and noise reduction reduces, and height distance is too small, and the circulation of air is affected.
The utility model is in order further to improve the noise reduction of array shutter, and preferably technical scheme also has, and the angle of the lateral wall of noise reduction circle and sound-absorbing snail inwall is 75 °; The angle of the left plate of blinds and blinds right panel is 130 °; Horizontal range in same blinds group between adjacent two blinds is 1/4 of blinds horizontal width; Height distance between two adjacent blinds groups is 1.5 times of blinds height.
