Description

The diamond cut dish
Technical field
The present invention relates to a kind of chopping disk (cutting blade), it has the carrier that is essentially metal, and this carrier has original sheet (Stammblatt) and is equipped with the particularly cutting edge (Schneidrand) of diamond dust (diamond particles) of abrasive particle.
Background technology
This chopping disk is well-known, and for example is applicable to the workpiece that processing is made by metal or metal casting.A kind of preferred embodiment in, chopping disk is divided into a plurality of sections, wherein, the external margin of each sections is equipped with abrasive particle, these abrasive particles by material fit remain on the cutting edge.The material that is positioned on the fringe region of each sections also can be embedded into abrasive particle.By such section of being divided into, not only improved stock-removing efficiency, but also reached the effect of cooling by the given shape of the notch between each sections, this is indispensable just for Metal Cutting.
But known diamond cut dish particularly segmented chopping disk has two main shortcomings: at first, their sound when cutting is bigger.Secondly, they especially are easy to form the crack on the bottom of the notch that is mainly used in cooling, and these notch great majority have the hole that can improve cooling effect in the inner.At this, the formation in crack may cause the damage of chopping disk owing to crackle expansion fast in the shortest time.
In the prior art, can run into the problem of extra high volume owing to sandwich.At this, between two metal original sheet, be provided with the core that particularly is made of copper by the soft metal.Can change the elastic modelling quantity of chopping disk and change its resonance response thus by this softer core relatively, thereby it is become more in operation.But this method is subjected to the restriction of the selection of the metal with suitable elasticity modulus and is subjected to the restriction of its fusing point.Be well known that in addition the geometric figure that cuts out produces positive influences to the resonance of chopping disk on original sheet.But the shortcoming of this way is, may damage the intensity of original sheet.
Summary of the invention
Now, the objective of the invention is to propose a kind of chopping disk, particularly a kind of segmented chopping disk, it produces noise that reduces and/or the stability with raising than known chopping disk.
Purpose of the present invention realizes by a kind of like this chopping disk, this chopping disk has the carrier that is essentially metal, this carrier has original sheet and is equipped with the particularly cutting edge of diamond dust of abrasive particle, wherein, described original sheet has a plurality of layers connected to one another, wherein be provided with at least two outer and intermediate layers that are arranged between the described skin that are made of metal, described intermediate layer has plastics and/or has fibre reinforced materials.Preferred embodiment in other parts, provide.
Basic design of the present invention is the sandwich form of this chopping disk, and is the intermediate layer of the design according to the present invention especially.In order to reach the purpose of noise attentuation, this intermediate layer can be made by plastics (synthetic material), and at this, thin film or paillon foil also can satisfy the feature in intermediate layer.Alternatively or additionally, this intermediate layer can have fiber reinforcement (fibre reinforced materials/structure), be used to improve the particularly stability on the transition portion of the bottom of going to the notch between the sections.According to the present invention, original sheet has a plurality of layers that are the connection fixed to one another of sandwich-like, and wherein, at least two skins are made of metal, and the intermediate layer that is provided with the intermediate layer that is made of plastics and/or is the fiber reinforcement form between these two skins.
At this, needn't make whole chopping disk all have this sandwich.Have big as far as possible area and extend on the bottom of notch just enough especially at chopping disk under the situation of plastic layer.Under fibre-reinforced situation, in order to reach stable purpose, be arranged to extend in the ring on the notch bottom it just enough.A kind of owing to have stable with characteristic noise damping and in the particularly preferred frame mode, the intermediate layer is made of fibre-reinforced plastics simultaneously.
Can make elastic modelling quantity realize that bigger jump also reaches better damping thus by the present invention.In addition, employed fiber and viscosity matrix (Matrix) form the obstacle to the crackle that trails, and have limited the growth of crackle in dish.If only need realize decay to sound, can adopt pure plastic substrate, preferred thermosetting plastic, silica gel matrix (Silikonmatrix) for example is as interlayer.
When the intermediate layer that use is made of plastics, it should be noted that advantageously damping layer made by the plastics that strengthen, at this, these plastics can withstand in short time at least and surpass 200 ℃ temperature load.This plastics are common general knowledge.In addition, for this plastic layer, also can adopt heat-resisting teflon.But, must use and can form the stable plastics that are connected with outer field metal.At last, as long as realize the large-area isolation (Entkopplung, buffering) of metal outer, the thickness of plastics is just unimportant.
In another embodiment of the present invention, the intermediate layer is the stabilized zone that constitutes by the fibreglass-reinforced metal of being made by metallic matrix-composite respectively.At this, as the fibreglass-reinforced metal known for example have carbon fiber strengthen aluminium alloy, ceramic fibre (for example strengthens, silicon carbide fibre, Si-Ti-C-O fiber (Tilano fiber), alumina fibre or boron fibre) aluminium alloy and glass fibre enhancing aluminium alloy, their parent metal has advantages of higher tensile strength and rigidity and less thermal coefficient of expansion.It can also use copper product or magnesium material.
The present invention preferably is used in the segmented chopping disk.In the case, the periphery of carrier is cut into sections, wherein, per two sections by one radially notch be separated from each other.For cooling purpose, notch has the crowned that is hole shape in the bottom.It also can be provided with additional hole on periphery.The external margin that is cut of each sections has abrasive particle, and abrasive particle is applied on its edge or is introduced in the material that constitutes the edge.
In addition, for damping state and/or stability advantageously, original sheet is the member that separates (independence) with cutting edge, and they at first are joined together by welding when producing.In this case, only on cutting edge, form sections.Like this, only be present in the original sheet according to sandwich of the present invention, wherein original sheet can fully be constructed to sandwich.Thus, can correspondingly simplify production, because this intermediate layer can be by the semi-finished product manufacturing of being produced.
In another embodiment, original sheet also constitutes cutting edge, thereby cuts out a plurality of sections when being cut into pieces on original sheet.Especially can be by welding be connected reliably with outer field extension and compare, in this case, the intermediate layer only is arranged on the central authorities of chopping disk, and just extends to the edge substantially.This embodiment also provides the advantage that is easy to manufacture view.
Even there are many plastics all to can be used for producing the intermediate layer that is different-thickness, but verified: when the intermediate layer comprises the damping layer of the thermosetting matrix with the variation of heatproof degree is particularly advantageous.In order to improve stability, the thermosetting matrix should be by fiber reinforcement, and at this, reinforcing material is made by independent glass fibre, basalt fibre or carbon fiber, or the fabric of being made by these fibers.At this, can fiber reinforcement be set a following zone at original sheet, these zones are the zones that are easy to suffer the crackle risk especially, for example are used to the border of cutting.Have or do not have fibre-reinforced uniform damping layer and preferably be cut into by semi-finished product, this has simplified production widely.
Preferably, semi-finished product to be used are manual laminated plastic, prepreg (Prepeg, sheet molding compound), sheet molding compound (" SMC ") or block molding compounds (" BMC ").Because special heatproof degree changes and damping capacity, uses phenolic resins, resistant to elevated temperatures epoxy resin or silicon (organic) resin as the thermosetting matrix especially.
