Abstract
The utility model discloses a kind of composite fret saw, it comprises wire rod and binder course, and described binder course is located at the surface of wire rod, and described binder course comprises the Graphene-resin bed being formed at wire surface, and described Graphene-resin bed is embedded with abrasive grains.Graphene-resin bed in the utility model has good percentage elongation and toughness, and scroll saw can be avoided in high shear rate, high tonnage or use procedure to produce crack, effectively extends the service life of scroll saw.In addition, Graphene-resin bed adds a certain amount of Graphene in resin, can reduce the frictional force adding man-hour, reduces the vibrations of scroll saw, promotes the cut surface flatness of processed object.
Description
Technical field
The utility model relates to a kind of composite fret saw.
Background technology
Saw blade cutting is a kind of processing method of cutting all kinds of monocrystal such as semiconductor, crystal, magnetic material, high technology ceramics and other hard brittle materials.Free abrasive wire saw has been widely used in the slice process of semiconductor crystal wafer at present, it utilizes steel wire to drive free abrasive (abrasive material adds liquid) to carry out removing materials, but due to the easy contaminated environment of abrasive material left after use free abrasive wire saw, cause industrial waste, and its working (machining) efficiency is low, therefore develops fixed-abrasive scroll saw and become the inevitable trend of industrial quarters.Compared to free abrasive wire saw, the advantage of fixed-abrasive scroll saw is to promote material removal rate and process abrasive material and can fully be utilized, and effectively can improve production capacity.
The Japan Patent of publication number JP2002331466 discloses a kind of resin fret saw, its object is to, by promoting abrasive material, abrasive material coming off in the process of saw blade cutting is prevented for the adhesive force of resin fret saw, wherein, there is a piano wire plating one electrodeposited coating of ormolu, and on this electrodeposited coating, form multiple spiral duct, a part for abrasive material is arranged in described spiral duct.Owing to have employed this structure, in cutting process, even if binder course is worn and shakes, this abrasive material also difficult drop-off, because larger abrasive material is arranged with spiral, can increase the expulsion efficiency of abrasive dust.And the surface area of electrodeposited coating is increased, and therefore make this binder course be increased for the adhesive force of this electrodeposited coating, thus prevent the disengaging of this binder course.But, coat wire rod again after abrasive material is mixed in organic material by this patent, therefore, when organic material solidifies, to easily cause abrasive material gathering or abrasive material to expose the inconsistent problem of rate, thus the adhesive force between binder course and abrasive material is reduced, and the situation causing abrasive material to come off produces.
Publication number be 201136688 Taiwan Patent disclose a kind of composite fret saw, it by being formed at online naked by resin layers abrasive material, then covers layer of metal layer, grasps abrasive material with this.But equally also often there is abrasive material and assemble and problem pockety in the technical scheme of this patent, and cause composite fret saw for the uneven phenomenon of cut surface of processing object in electroplating process.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide one can improve cutting speed and bear tension force, reach and effectively shorten process time and increase the service life, and reduce the frictional force adding man-hour and the composite fret saw promoting the cut surface flatness of processed object.
For achieving the above object, the utility model is by the following technical solutions:
A kind of composite fret saw, it comprises wire rod and binder course, and described binder course is located at the surface of wire rod, and described binder course comprises the Graphene-resin bed being formed at wire surface, and described Graphene-resin bed is embedded with abrasive grains.
Described abrasive grains is one or more the mixing in diamond particles, cubic boron nitride particle, alumina particle, silicon oxide particle.
Described wire rod is qin steel wire, copper facing qin steel wire or stainless steel wire.
Described wire rod strandedly to be formed by two or three bare wire is mutual.
The utility model adopts above technical scheme, and Graphene-resin bed has good percentage elongation and toughness, and scroll saw can be avoided in high shear rate, high tonnage or use procedure to produce crack, effectively extends the service life of scroll saw.In addition, Graphene-resin bed adds a certain amount of Graphene in resin, provides a kind of effect of lubrication, can reduce the frictional force adding man-hour, reduces the vibrations of scroll saw, promotes the cut surface flatness of processed object.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is the structural representation of a kind of composite fret saw of the utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises wire rod 1 and binder course, and described binder course is located at the surface of wire rod 1, and described binder course comprises the Graphene-resin bed 2 being formed at wire rod 1 surface, and described Graphene-resin bed 2 is embedded with abrasive grains 3.
Described abrasive grains 3 chooses the material with high rigidity, can be one or more the mixing in diamond particles, cubic boron nitride particle, alumina particle, silicon oxide particle.
Described wire rod 1 is qin steel wire, copper facing qin steel wire or stainless steel wire.Be preferably copper facing qin steel wire, to be increased the adhesive force between electrodeposited coating and bare wire by the layers of copper of qin steel wire.
Described wire rod 1 strandedly to be formed by two or three bare wire is mutual.The scroll saw of this spline structure has higher pliability.
Resin in Graphene-resin bed 2 in the utility model can be epoxy resin, phenolic resins, methacrylate resin or its combination, is coated with, obtains flatness preferably scroll saw by solvent-free mode.
Graphene uniform can be dispersed in resin by the dispersal device of a tool ultra-high shear power by the forming method of Graphene-resin bed 2.
