Description
Technical field
The present invention relates to a kind of grinding and use the abrasive band, especially relate to a kind of diamond abrasive band that is applicable to that hard brittle materia grinds.
Background technology
The diamond abrasive band is that coated or electro-deposition forms diamond layer on metal or non-metal substrate by diamond abrasive, the ground of diamond layer is bonded in rubber-plastics material substrate (matrix) again and goes up moulding.Also can bond earlier on the rubber-plastics material substrate metal or non-metal substrate, the method for taking coated or electro-deposition again is cemented in the diamond powder on the surface of bottom material and moulding.Diamond abrasive band and common aluminium oxide, the difference in carborundum abrasive band are, the diamond abrasive band can be used for the high-efficient grinding hard brittle materia, as stone material, glass, pottery, jewel etc., and common abrasive band is mainly used in lapped face hardness materials with smaller, as steel, aluminium etc.
Existing diamond abrasive band (referring to Fig. 1), its diamond layer are to be gone up in metal substrate 13 (or non-metal substrate) through binding agent 12 cementations (or electro-deposition) by diamond abrasive 11 (diamond particles) to form.Again the ground 13 of diamond layer is bonded in rubber and plastic abrasive band matrix 14 upper surfaces and moulding.Rubber and plastic abrasive band matrix 14 shape of cross sections are straight thin rectangle, and promptly dual- side 141 and 142 is right-angle side (being that two sides are vertical plane).Because when belt sander drives the abrasive band rotation work, the direction (shown in the arrow) that pushes of workpiece P is that the direction of motion (perpendicular to paper) with the abrasive band is vertical relation.When workpiece P base and edge, abrasive band rigidly connect the moment of touching, can produce higher impulsive force, the diamond layer at edge, abrasive band is suffered damage, after work a period of time, the edge, abrasive band weares and teares easily, breaks, peels off even comes off.And can damage workpiece P again.In the actual use in diamond abrasive band, generally all be because of the crossing quick-wearing, peel off of boart boart belt edge, coming off causes and causes the whole piece abrasive band to lose efficacy.After the abrasive band edge abrasion, peeling off, come off, can cause that also the broken limit of glass (collapsing the limit) phenomenon takes place workpiece (as glass plate) when chamfering, in case therefore the edge, abrasive band weares and teares, peels off or obscission, although other parts are also better, but the whole piece abrasive band must be changed, thereby obviously reduce the service life in diamond abrasive band, cause the abrasive band waste serious, increase processing cost.
Publication number is that the application for a patent for invention of CN101664904 discloses a kind of emery cloth, abrasive band abrasive material and manufacture craft thereof, it comprises: behind the solder pre-alloyed powder batch mixing again with diamond/cubic boron nitride compounding, be cold-pressed into thin slice, the thin slice soldering sinters flexible flake into.Flexible flake is bonded in emery cloth, abrasive band substrate surface, promptly forms wear-resisting emery cloth, abrasive band.This invention provide a kind of can the convenient and swift method that braze welding diamond/cbn layer is applied to make multiple strong wear-resisting emery cloth, abrasive band abrasive material, its manufacture craft is simple, nontoxic, pollution-free, the anti-wear performance of the abrasive material of preparation strengthens greatly, makes the operating efficiency and the service life of emery cloth, abrasive band instrument increase substantially.
Summary of the invention
The objective of the invention is in order to overcome the phenomenon that existing boart boart belt edge is damaged easily, provide a kind of boart boart belt edge of can effectively avoiding to damage phenomenon, significantly improve diamond abrasive band service life, the diamond abrasive band that cuts down finished cost.
The present invention is provided with abrasive band matrix and abrasive material, abrasive material is provided with ground and abrasive material, ground adheres to the surface of abrasive band matrix, abrasive material adheres on the ground, its characteristics are that the upper surface of abrasive band matrix is plane and parallel with lower surface, and the two sides of abrasive band matrix are inclined-plane or curved surface, the two sides of abrasive band matrix and the angle between the upper surface are all greater than 90 °, and the abrasive material coverage comprises the upper surface and the two sides of abrasive band matrix.
Described abrasive material can be abrasive materials such as diamond layer, silicon carbide layer, boron carbide layer or boron nitride.
Described abrasive material coverage also can comprise the lower surface of abrasive band matrix, is about to abrasive band matrix surface all standing.
The best planform in two sides of described abrasive band matrix is identical and be symmetrical arranged, and described side can be inclined-plane or curved surface; Described inclined-plane can be monocline face or double inclined plane, the inclined-plane that is in the shape of the letter V that described double inclined plane preferably is made of 2 inclined-planes; Described curved surface can be single-arc shaped face or two arcwall face, the arcwall face of the V-shaped parabolic that the described pair of arcwall face preferably is made of 2 arcwall faces.
The two sides of described abrasive band matrix and the transition between upper surface and/or the lower surface are for preferably being the arc rounding off.
Compared with the prior art, beneficial effect of the present invention is as follows:
Because the transition angle between matrix two sides, abrasive band and the upper surface is all greater than 90 °, and be arc-shaped transition.Be to be non-perpendicular (that is the dual-side of abrasive band matrix cross sections is the on-right angle limit) between matrix two sides, abrasive band and the upper surface, and the abrasive material coverage comprise the upper surface and the two sides of abrasive band matrix.During work, abrasive band and workpiece (as glass plate) are when contacting, and the edge of diamond layer can be avoided contacting with the direct of glass plate on the one hand, and on the other hand because the arc rounding off, glass plate can play cushioning effect when contacting with the diamond abrasive band.Such structure can make increase greatly the service life in diamond abrasive band, and can not damage glass plate, and processing cost significantly reduces.Because the present invention also can be designed to two-sided abrasive band (the abrasive material coverage comprises upper surface, lower surface and the two sides of abrasive band matrix, is about to abrasive band matrix surface all standing).After upper surface diamond layer usefulness finished, turning over one side had diamond layer to use again, can prolong the service life in diamond abrasive band greatly, significantly saves cost, avoids causing waste, improves the cost performance in diamond abrasive band like this.
