Description
Technical field
The utility model relates to a kind of saw blade, especially relates to a kind of silent saw blade matrix
Background technology
At present, the silent saw blade matrix of extensive use mostly is a sandwich structure the most, promptly be made of both sides steel disc and intermediate layer quieter material, the quieter material in intermediate layer adopts metal materials such as aluminium foil, Copper Foil, is combined into stepped construction by welding manners such as high frequency spot welding, brazing, silver soldering.Have the silent saw blade matrix intermediate layer of individual types to adopt nonmetallic materials, for example, plastics, rubber, fiber etc. combine by bonding or spot welding mode.The mode of taking joint-cutting to fill clay that also has makes saw blade eliminate big noise in cutting process.
The U.S. Pat 3981216 that announce in September, 1976 discloses a kind of low noise high-speed cutting saw blade, be exactly by cutting ditch seam on the monolithic saw bit matrix, the mode of filling scolder or other elasticity thing reduces the noise of saw blade under high-speed cutting in stitching toward ditch then.
The U.S. Pat 3990338 that announce in November, 1976 discloses a kind of stacked saw blade, and the interlayer of use is metal net shaped structure, and this network structure layer is by materials and the mutually bonding saw bit matrix that forms of the sheet metal of both sides such as epoxy glue, scolder, bonding agents.If use epoxy glue bonding, then in epoxy glue, add metallic particles to reach the purpose of conduction, so just can carry out stitch bonds to matrix.If use welding powder (as the silver soldering powder) to replace epoxy glue or other bonding agent, metal net shaped structure can be dipped in the welding powder solution, perhaps welding powder is evenly spread on the wire netting and realize, can carry out spot welding, the saw blade of being produced can reach the purpose that reduces vibrations and reduce noise.
The U.S. Pat 4034639 that announce in July, 1977 provides a kind of silent saw blade, by on the one side of individual layer saw blade in conjunction with viscous-elastic material layer and layer of metal layer, the diameter of this viscous-elastic material layer and metal level is less than the diameter of saw bit matrix, coat a circle wearing layer in their mutual circumferential location, reach the purpose that reduces noise, can reduce about 30% noise.This elastomeric layer can adopt polymeric material and plasticiser be combined into.Polymeric material adopts acrylic acid esters co-polymer and acrylic copolymer, acrylic acid for example, methacrylic acid, acrylonitrile, methacrylonitrile, acrylamide, Methacrylamide.This metal level preferably has identical or close heat conductivity with matrix.
The U.S. Pat 4867025 that announce in September, 1989 provides a kind of saw blade, and saw blade is a sandwich structure.Mainly reach the effect that reduces vibrations and reduce noise by the intermediate layer, the mode by multiple spot welding combines active gage and middle noise reduction layer.But but the material of energy absorption-type and solder type is adopted in the intermediate layer, has heat conductivity simultaneously.Usually adopt copper sheet, or copper alloy, as brass, bronze, copper manganese aluminium, copper tin manganese aluminium etc.But the saw blade of this spot welding mode combination is in high-speed cutting, and under the effect of a large amount of heats, easy deformation even disengaging are split, and therefore generally can only be used to have water-cooled wet cutting.And easily cause the local deformation of matrix, and therefore after welding is finished, need carry out stress adjustment and calibration, improved manufacturing cost.
Chinese patent 99112448.0 provides a kind of silent circular saw blade and manufacture craft thereof, and saw blade or saw bit matrix are two-layer or two-layer above work substrates and to place bloop between the work substrate to be connect by some solder joints be whole laminated construction.Its manufacture craft comprises the steps such as processing, welding and after welding treatment of work substrate and bloop.Have reduction or abate the noise the characteristics that improve saw blade intensity or save material.Though this patent is mentioned available laser weld matrix is linked together, lack concrete implementation method.
Chinese patent application 200410009101.1 provides a kind of noise reduction sound diamond section and manufacture method.Matrix is the composite construction more than three layers or three layers, and the adjacent layer of this composite construction is a unlike material, and levels is a manganese steel plate, and the intermediate layer is a copper coin, and matrix is made in compound weldering.The diamond cutting body is by multiple metal powder material and diamond compression moulding.Diamond cutting body and complex matrix are mosaic texture, and promptly the edge of matrix is embedded in the cutting body.Diamond cut body and complex matrix pass through Thermocompressed sintering and forming.
Notification number provides a kind of novel metalloid material compound silent saw blade matrix for the Chinese utility model patent of CN2654319, center mounting hole and tank are set on the matrix, be made up of the Silencing clip synusia that additional one deck nonmetallic materials between the two-layer work substrate are made, work substrate and Silencing clip synusia adopt the spot welding mode to be connected to whole laminated construction.
EUROPEAN PATENT OFFICE's disclosed publication number of in May, 1996 is the manufacture method that the patent of JP8126912 (A) provides the saw blade of the low vibration of a kind of low noise, and its intermediate layer is exactly the resin bed of viscosity.This resin bed forms with the steel disc bonding compacting of both sides.The steel disc of both sides is then fixed by spot welding or riveted way.The saw blade that this method is produced is under a large amount of heats that high-speed cutting produces, and the intermediate layer may be melted or the solder joint fusing, thereby causes coming off.Therefore, can only add water cooling uses.Can't be used for dried cutting.
EUROPEAN PATENT OFFICE's disclosed publication number of in September, 2000 is that the patent of KR20000054871 (A) provides a kind of multiple spot welding manufacture method of producing the low noise saw blade, and the intermediate layer is conduction or nonconducting damping absorbed layer.If conductive layer then directly carries out spot welding.If the non electrically conductive material layer, then with the material layer punching, the Metal Ball of filled conductive is as the welding auxiliary material, and then carries out spot welding.The above-mentioned silent saw blade of mentioning may cause intermediate layer fusing or solder joint fusing, thereby cause coming off under a large amount of heats that high-speed cutting produces, and therefore, can only use when water cooling (wet and cut) is arranged, and can't be used for dried cutting, and manufacturing cost is higher.
Summary of the invention
The purpose of this utility model provides a kind ofly both cut applicable to wet, cut on-deformable silent saw blade matrix again applicable to dried.
The utility model is provided with 2 steel discs and noise reduction layer, and the noise reduction layer is located between 2 steel discs, and 2 steel discs are provided with coaxial central shaft hole with the noise reduction layer, and 2 steel discs interconnect, and it is characterized in that described connection is a laser weld between 2 steel discs.
