Description
Technical field
The present invention relates to a kind of grinding-polishing technical field of tools, more particularly to soldering diamond flap disc.
Background technology
Existing flap disc is made up of many small grindings and core wheel two parts, and small grinding includes a base cloth layer, a metal
Sedimentary and a diamond layer, the diamond layer are by many diamonds inlayed using electrochemical deposition process by metal parcel
Little particle is formed；The base cloth layer of small grinding is low using fiber cloth, non-woven fabrics, the weaving material such as canvas or cotton, heat-proof quality；Base
Carried out using common glue be bonded between layer of cloth and core wheel, heat-resisting ability is poor.When flap disc rotates in high speed, heat
Amount is easily delivered between base cloth layer and core wheel from base cloth layer, and common glue, which is easily heated, reduces its adhesive property, causes to take turns
Core reduces to the hold of small grinding, small grinding stationarity is poor, the potential safety hazard for coming off and throwing away be present.
The manufacture method of the existing small grinding of flap disc has following several：One kind is that coating silicon carbide etc. is commonly ground in base fabric
Feed composition consolidation forms, and because resin is low to the hold of abrasive material, base fabric shear strength is also low, so the grinding uses the longevity
Life is very short.Another kind is that the abrasive materials such as diamond are embedded on metal deposition layer using the method for metal electrodeposition, such electricity
Plating grinding is higher than resin bonded grinding abrasive material exposure, and metal is also more preferable to the hold of abrasive material, therefore electroplates grinding and ground than resin
Piece grinding efficiency is higher, service life is also longer.But the abrasive material in plating grinding is the metal deposition layer covering by one layer very thin
, belong to physical bond, metal level is not also fine to the hold of diamond, and it is easy to fall off the abrasive materials such as diamond to be also present, makes
The shortcomings that being fallen short of with the life-span.
The corner of existing small grinding is sharp, and the flap disc edge of combination is very sharp, and security is poor；The small mill of other flap disc
Piece arrangement is overstocked, chip removal and the problems such as bad of radiating.
The content of the invention
The invention provides a kind of new soldering for the corase grind processing for being mainly used in the hard brittle materials such as stone material, glass, ceramics
Diamond flap disc, improve heat resistance, grinding efficiency, security and the service life of flap disc.
To reach above-mentioned purpose, the present invention is achieved by the following technical solutions：
A kind of soldering diamond flap disc, it includes core wheel and affixed some small grindings thereon, and each small grinding is mutual
A juxtaposition part is arranged in the excircle annular region of core wheel, and small grinding is with using high temperature resistant adhesive Nian Jie between core wheel
Together, the small grinding is made up of heat insulation layer, brazing layer, and wherein brazing layer is mutually tied with heat insulation layer using a kind of following mode
Close,
（1）, brazing layer the back side spraying heat proof material formed heat insulation layer；
（2）, in the back side hot pressing composite heat resistance plastics of brazing layer or heat-resisting base fabric form heat insulation layer.
Further, the material of the back side spraying of the brazing layer is that the temperature capacities such as polytetrafluoroethylene (PTFE) or macromolecule resin are strong
Material.The brazing layer of soldering diamond flap disc is made up, pricker of soldering diamond or cubic boron nitride abrasive grain on steel disc
The proud exposure of diamond or cubic boron nitride abrasive grain on layer reaches itself 2/3rds.In each small grinding
Several apertures are opened up, the diameter of aperture can be used for the chip removal and the radiating effect that improve grinding between 2-10mm.
Small grinding in soldering diamond flap disc also uses below extremely in addition to affixed with high temperature resistant binder and core wheel
A kind of few mode carries out affixed：
（1）, be provided with axis hole among the core wheel, be circumferentially with becket along axis hole, each small grinding by horizontal stripe with it is golden
The connection of category ring simultaneously is mutually interconnected into form biplate conjoined structure with the small grinding of small grinding diametrically；
（2）, each small grinding inward flange protrude a part of triangle weld part, in the superposition of weld part between adjacent grinding
Locate firm welding；
（3）, some salient points or projection are provided with above core wheel, small grinding is provided with the hole clipping being engaged with salient point or projection,
Core wheel is connected with small grinding by snap fit；
（4）, it is each it is small grinding inward flange one is formed by soldering.
Further, each small grinding outward flange carries out chamfered, is allowed to form arcuate edge.
Beneficial effects of the present invention：The high heat insulation layer of heat resistance effectively prevents heat transfer between small grinding and core wheel
Adhesive on, prevent adhesive is heated from reducing viscosity；The high temperature resistant adhesive used between small grinding and core wheel further carries
The high heat resistance of flap disc, caking property；The centre bore iron hoop of small grinding horizontal stripe and core wheel equably welds together, small grinding
On the hole of front-right and core wheel relative projection coordinate buckle into, being welded to each other between adjacent grinding, increase core wheel to small mill
The hold and stationarity of piece；Several apertures in the small grinding of flap disc, are advantageous to the discharge of coolant and iron filings, simultaneously
So that radiating is more abundant；Flap disc outward flange chamfering improves the security of flap disc.
