Abstract
The utility model provides a wind power brazing saw blade. The saw blade comprises a main base body, wherein tool bit base bodies are connected with the edge of the main base body; and wear-resistant materials are arranged on the tool bit base bodies. According to the utility model, chemical and metallurgical bond of the wear-resistant materials, bonding agents and the metal base body interface can be realized by the brazing technology and the bonding strength is higher; and meanwhile, the main base body is separated from the tool bit base bodies and diamond is brazed on the tool bit base bodies, thus avoiding high temperature heating of the main base body and ensuring the strength of the main base body.
Description
Technical field
The utility model belongs to the grinding tool field, particularly a kind of soldering saw blade that is used for wind-powered electricity generation.
Background technology
The employed material of wind electricity blade belongs to composite (mainly being fiberglass or carbon fiber); Have very special performances characteristics; Include: 1. hardness is high, and the wind-powered electricity generation fan blade is mainly used in the open air, need accept the infringement of dust storm for a long time; So need have very high wearability, so the material of using all is the high material of hardness; 2. viscosity is big, and the wind-powered electricity generation fan blade is because environment for use abominable, thus except high rigidity, also need have than high toughness, so employed material has certain viscosity.
More than two dot characteristics determined the employed saw blade of cutting of wind-powered electricity generation fan blade should cut the high viscosity that the high rigidity product overcomes material again, so the saw blade that uses at first will possess high cutting ability, prevent sticking cutter again.
According to above requirement, can know that the saw blade that can be applicable to the cutting wind electricity blade at present is for electroplating saw blade.But electroplate saw blade some comparatively significant disadvantages are arranged.Because its diamond is controlled through the mechanical embedding power of electroplating with the nickel metal, therefore when receiving greatly cutting force, diamond comes off easily.And because the plating characteristics, diamond must over half could the assurance of embedding be controlled.Therefore it exists the life-span short, inefficient defective.
The utility model content
The utility model provides a kind of wind-powered electricity generation soldering saw blade for solving the problems of the technologies described above, and it has comprised main matrix, wherein, is connected with the cutter head matrix at the edge of main matrix, and the cutter head matrix is provided with high-abrasive material.Soldering tech can be realized high-abrasive material, bond (brazing alloy material) and metallic matrix surface chemistry metallurgical binding, has higher binding strength.Simultaneously main matrix and cutter head matrix are separated, diamond brazing can be avoided main matrix is carried out heat on the cutter head matrix like this, guarantees its intensity.
Preferably, cutter head matrix and main matrix are through laser weld together.
Preferably, on the cutter head matrix, be provided with hole slot.
Preferably, on main matrix, be provided with perforate.
Preferably, high-abrasive material is a diamond, and said granularity is between the 35-60 order.
Preferably, diamond is welded on the cutter head matrix, and scolder is Ni-based scolder.
Preferably, on main matrix, be connected with a plurality of said cutter head matrixes, and keep at a certain distance away between a plurality of cutter head matrix.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Shown in Figure 1 is the structural representation of the utility model wind-powered electricity generation soldering saw blade.
The specific embodiment
As shown be the embodiment of the utility model, as shown in the figure, the utility model provides a kind of soldering saw blade, and it is that method with soldering makes high-abrasive material and saw bit matrix generation chemical bond, the saw blade that welds together securely with solder fusing.
Soldering tech can be realized high-abrasive material, bond (brazing alloy material) and metallic matrix surface chemistry metallurgical binding, has higher binding strength.Because the bond strength on the interface is high, so only need very thin bond thickness just to be enough to control securely abrasive particle, its exposed height can reach 70%～80%, makes the utilization of abrasive material more abundant, has improved the life-span and the working (machining) efficiency of instrument greatly.Compare with conventional art, the permission maximum of diamond tool goes out the sword value can be increased more than 50%, the power consumption of instrument do not increase or the condition that decreases under, the diamond consumption of workpiece material reduces over half on the unit volume.Compare with plating tool, also shown incomparable advantage.
But because soldering need carry out heat, and wind-powered electricity generation use saw blade, and general matrix size is bigger, under the temperature of spending 1000, carry out more integral braze-welded, the one, the wasting of resources, the 2nd, understanding influence the intensity of matrix, and then influences service life.
The utility model provides a kind of new wind-powered electricity generation soldering saw blade, has comprised main matrix 11, is provided with cutter head matrix 12 at the edge of main matrix, and cutter head matrix 12 is provided with high-abrasive material 121.High-abrasive material can be diamond, cubic boron nitride or silicon nitride etc.In the present embodiment, preferred, cutter head is that braze welding diamond is made on cutter head matrix 12, and main matrix 11 was opened with the cutter head matrix in 12 minutes, and diamond brazing can be avoided main matrix is carried out heat on cutter head matrix 12 like this, guarantees its intensity.Brazing temperature is approximately 1030 degree, and cutter head matrix 12 passes through laser weld together with main matrix 11.
Preferred, on cutter head matrix 12, have hole slot 122, hole slot 122 can play the effect of chip removal, heat radiation.Used diamond grit is generally between the 35-60 order on the cutter head, evenly arranges.Scolder is preferably selected Ni-based scolder for use, and component is nickel, chromium, boron, silicon.
The cutter head matrix of the utility model is arcuation, on same main matrix, is connected with a plurality of cutter head matrixes, and the arrangement that keeps at a certain distance away between a plurality of cutter head matrix.
