Abstract
The damping noise-reducing base-body sound-suppressing ring saw blade is characterized by that saidbase body is composed of combined three layers metal plate, in which two outer-layer metal plates is made of constructional steel plate, and middle sandwich plate possessing the action of damping and reducing noise is made of pure metal plate or alloy plate. Said invention can reduce cutting noise to 80 dB.
Description
The present invention relates to the saw blade of a kind of cutting stone material, concrete, timber, artificial composition floor etc.
Noise pollution, air pollution and water pollute and constitute current three major source of pollution.If people work under 104dB noise circumstance condition, there is deaf workman in various degree to account for 32%, heart disease, hypertension, the neurasthenic incidence of disease exceed several times than general workshop workman.The noise serious environment pollution, and become one of main public hazards that jeopardize people ' s health.China GBJ87-85 regulation: work in 8 hours, the noise limit value is 90dB.The noise sanitary standard of developed country is more strict.In recent years, generally come into one's own, adopt new material, new technology, new design to reduce noise radiation and obtained gratifying effect in the preventing and controlling of our country and developed country's noise.
Diamond and sintered carbide circular saw are the instruments of cutting stone material, concrete, timber, artificial composition floor etc.The raising of the development of building industry and the difficulty of industrial processes provides good opportunity for the development of diamond saw blade.But saw blade also brings noise nuisance when cutting material.Usually generally more than 120dB, it is big that the noise of cutting timber is also wanted for cutting noise.
For reducing the noise pollution of saw blade, the common method that adopts both at home and abroad is the design sound attenuation hole or the seam (is the patented technology of ZL96236950.0, ZL94219918.9 as the patent No.) of eliminating the noise on the matrix of saw blade at present, also have plenty of at the connection position of saw blade and cutting machine and increase flexible gaskets, make friction and impact the propagation of sound wave on matrix that produces and be subjected to damping, reduce audio frequency resonance, reach the purpose that reduces noise intensity, but can't fundamentally eliminate noise.
The objective of the invention is to overcome the deficiency of above-mentioned prior art, a kind of silencing circular saw disc with damping noise-reducing function is provided, make the cutting noise of saw blade meet national standard, to eliminate noise nuisance.
The objective of the invention is to realize by following technical proposals:
Silencing circular saw disc with damping noise-reducing base body has matrix, technical scheme of the present invention is that described matrix is made of the three-layer metal sheet material that is compound in together, wherein two outer metal plates are the structural steel steel plate, and the therebetween laminate that plays the damping noise-reducing effect is a kind of simple metal plate or alloy sheets.
In the technique scheme, described two outer metal plates materials can be carbon constructional quality steel, can be 45 steel.Two outer metal plates materials also can be structural alloy steel, and material can be 65Mn, 60Si2Mn, 45Mn2V, 50Mn2V, 40Cr, 20Cr or 30CrMo.Described intermediate course sheet material matter can be fine copper or fine aluminium.Intermediate course sheet material matter also can be copper alloy, manganese alloy or manganese/nickel alloy.
Saw blade of the present invention, adopt a kind of simple metal plate of steel plate one vibration damping or alloy sheets-steel plate complex matrix, because intermediate course sheet material matter is a kind of preferably simple metal of slip property or alloy, in working angles, the interlayer metal or alloy is transformed into interior energy with a part of vibrational energy, makes interlayer metal or alloy dislocation produce slippage or climbs; Part vibrational energy becomes thermal energy consumption and falls; Again because saw bit matrix adopts sandwich design, because the resonant frequency of different metal is inequality, so, in working angles, can not produce resonance.Thereby produce the function of good damping vibration, reach erasure effect.The present invention makes silent saw blade with the damping function material, uses the damping principle of composite to vibration, and integral material produces damping to vibration, and the resonance of the saw blade that causes when fundamentally eliminating cutting can fundamentally abate the noise.After tested, the cutting noise of saw blade of the present invention below 80dB, thereby eliminated noise nuisance.
The present invention will be described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a welding cutter head diamond disc of the present invention.
Fig. 2 is a thermal pressing sintering diamond saw blade of the present invention.
Fig. 3 is a sintered carbide circular saw of the present invention.
Fig. 4 is along the cutaway view of A-A line among Fig. 1.
Fig. 5 is along the cutaway view of B-B line among Fig. 2.
Fig. 6 is along the cutaway view of C-C line among Fig. 3.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, three kinds of saw blades of the present invention all have matrix, described matrix is made of the three-layer metal sheet material 1,2,3 that is compound in together, wherein two outer metal plates 1,3 are the structural steel steel plate, and the therebetween laminate 2 that plays the damping noise-reducing effect is a kind of simple metal plate or alloy sheets.Described two outer metal plates, 1,3 materials can be carbon constructional quality steel, can be 45 steel.Described two outer metal plates, 1,3 materials can be structural alloy steel, can be 65Mn, 60Si2Mn, 45Mn2V, 50Mn2V, 40Cr, 20Cr or 30CrMo.Described therebetween laminate 2 materials can be fine copper or fine aluminium.Therebetween laminate 2 materials also can be copper alloy, manganese alloy or manganese/nickel alloy.Two outer metal plates 1,3 thickness equate that therebetween laminate 2 thickness that play the damping noise-reducing effect are between 0.05-0.15mm.Certainly, also can assist on the matrix and be provided with bloop.
Below be preparation process of the present invention:
1, the preparation process of welding diamond disc and sintered carbide circular saw: (1) sheet material deoils, and (2) cold water cleans, (3) pickling, (4) cold water cleans, and (5) hot water cleans, (6) steel plate Fast Heating, (7) composite plate is rolling, (8) punching out matrix, (9) heat treatment, (10) grinding, (11) welding cutter head, put the first edge on a knife or a pair of scissors (12), (13) preservative treatment, (14) print trade mark, (15) finished product packing.
