Description
Technical field
The present invention relates to a kind of grinding-polishing technical field of tools, particularly relate to braze welding diamond flap disc.
Background technology
Existing flap disc is made up of many little abrasive discs and core wheel two parts, and little abrasive disc comprises a base cloth layer, a metal deposition layer and a diamond layer, and this diamond layer is utilized electrochemical deposition process to be wrapped up by metal the diamond granule inlayed to form by many; The base cloth layer of little abrasive disc adopts the materials such as fiber cloth, non-woven fabrics, weaving canvas or cotton, and heat-proof quality is low; Adopt common glue to carry out between base cloth layer with core wheel bonding, heat-resisting ability is poor.When flap disc at High Rotation Speed time, heat is easily delivered between base cloth layer and core wheel from base cloth layer, common glue is easily heated and reduces its adhesive property, causes core wheel to reduce the hold of little abrasive disc, little abrasive disc stationarity is poor, and existence comes off the potential safety hazard thrown away.
The manufacture method of the little abrasive disc of existing flap disc has following several: one is that the conventional abrasive material composition consolidation such as coating silicon carbide forms on base cloth, and because the hold of resin to abrasive material is low, base cloth shear strength is also low, so this abrasive disc is very short for service life.Another kind adopts the method for metal electrodeposition that the abrasive materials such as diamond are embedded on metal deposition layer, such plating abrasive disc is higher than the exposure of resin bonded abrasive disc abrasive material, the hold of metal pair abrasive material is also better, and therefore plating abrasive disc is higher than resin abrasive disc grinding efficiency, service life is also longer.But the abrasive material on plating abrasive disc covers by the metal deposition layer that one deck is very thin, and belong to physical bond, metal level is not also fine to adamantine hold, also there is the abrasive materials such as diamond and easily comes off, the shortcoming fallen short of service life.
The corner of existing little abrasive disc is sharp-pointed, and the flap disc edge of combination is very sharp, poor stability; The little abrasive disc arrangement of flap disc is overstocked in addition, chip removal and the problem such as heat radiation is bad.
Summary of the invention
The invention provides a kind of novel braze welding diamond flap disc being mainly used in the corase grind processing of the hard brittle materials such as stone material, glass, pottery, improve the heat resistance of flap disc, grinding efficiency, security and service life.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of braze welding diamond flap disc, it comprises core wheel and affixed some little abrasive disc thereon, the mutual juxtaposition part of each little abrasive disc is arranged in the excircle annular region of core wheel, high temperature resistant adhesive is adopted to bond together between little abrasive disc and core wheel, described little abrasive disc is made up of heat insulation layer, brazing layer, wherein brazing layer and heat insulation layer adopt following a kind of mode to combine
(1), heat insulation layer is formed at the back side of brazing layer spraying heat proof material;
(2), at back side hot pressing composite heat resistance plastics or the Nai Rejibu formation heat insulation layer of brazing layer.
Further, the material of the back side spraying of described brazing layer is the material that the temperature capacity such as polytetrafluoroethylene (PTFE) or macromolecule resin is strong.The brazing layer of braze welding diamond flap disc is made up of braze welding diamond on steel disc or cubic boron nitride abrasive grain, and the diamond on brazing layer or the proud exposure of cubic boron nitride abrasive grain reach itself 2/3rds.Each little abrasive disc described offers several apertures, and the diameter of aperture can for improving chip removal and the radiating effect of abrasive disc between 2-10mm.
Little abrasive disc in braze welding diamond flap disc except with high temperature resistant binder and core wheel affixed except, also adopt following at least one mode to carry out affixed:
(1), be provided with axis hole in the middle of described core wheel, be circumferentially with becket along axis hole, each little abrasive disc is connected by horizontal stripe with becket and is interconnected into mutually with this little abrasive disc little abrasive disc diametrically and forms biplate conjoined structure;
(2), each little abrasive disc inward flange gives prominence to a part of triangle weld part, in the superposition place firm welding of weld part between adjacent abrasive disc;
(3), be provided with some salient points or projection above core wheel, little abrasive disc is provided with the hole clipping matched with salient point or projection, and core wheel and little abrasive disc are connected and fixed by snap fit;
(4), each little abrasive disc inward flange forms one by soldering.
Further, described each little abrasive disc outward flange carries out chamfered, makes it to form arcuation edge.
Beneficial effect of the present invention: on the adhesive that the heat insulation layer that heat resistance is high effectively stops heat to be delivered between little abrasive disc and core wheel, prevents adhesive to be heated reduction viscosity; The high temperature resistant adhesive adopted between little abrasive disc and core wheel further increases heat resistance, the caking property of flap disc; The projection that little abrasive disc horizontal stripe welds together equably with the centre bore iron hoop of core wheel, the hole of little abrasive disc front-right is relative with on core wheel coordinate buckle into, being welded to each other between adjacent abrasive disc, increase core wheel to the hold of little abrasive disc and stationarity; Several apertures on the little abrasive disc of flap disc, are conducive to the discharge of cooling fluid and iron filings, make heat radiation more abundant simultaneously; Flap disc outward flange chamfering improves the security of flap disc.
