Description

New Abrasive Belt

Technical field

This utility model relates to a kind of New Abrasive Belt.

Background technology

The grinding tool that existing grinding machine uses is usually emery wheel and two kinds of abrasive band, and emery wheel is that in grinding tool consumption is Greatly, use the widest one in face, high speed rotating during use, can to metal or the cylindrical of non-metal workpiece, Inner circle, plane and various profiles etc. carry out roughly grinding, partly refining and refine and fluting and cut-out etc., abrasive band Belong to coated abrasive tool, referred to as flexible abrasive product, ratio solid grinding tool emery wheel during polishing, the most flexible and safety, Precision is higher, the advantage of grinding low cost, and in prior art, grinding wheel speed is high, when workpiece base and sand The moment that belt edge has just contacted, higher impulsive force can be produced, easily make the diamond layer at edge, abrasive band be subject to Infringement, after a period of operation, edge, abrasive band easily weares and teares, rupture, peel off and even come off.And Workpiece can be damaged again.Diamond abrasive band actually used in, be typically all because of diamond abrasive band Edge cross quick-wearing, peel off, coming off causes and causes whole piece abrasive band to lose efficacy.When abrasive band edge abrasion, Peel off, come off after, also can cause workpiece that glass broken limit phenomenon, the most once limit, abrasive band occur when chamfering Edge weares and teares, peels off or obscission, although other parts are also preferable, but whole piece abrasive band must be changed, Thus substantially reduce the service life of diamond abrasive band, cause abrasive band waste serious, increase processing cost.

Summary of the invention

For above-mentioned technical problem, this utility model provides one to be difficult to damage workpiece and can be to workpiece Carry out the New Abrasive Belt of multiple grinding.

Realize the technical solution of the utility model as follows:

New Abrasive Belt, including matrix, tack coat and abrasive material, tack coat is bearing in one end of matrix, described The width of one end of substrate support tack coat, less than the width of this matrix other end, two sides of matrix are Inclined-plane or arcwall face, tack coat cover on matrix, abrasive material cover on tack coat after, tack coat and Two sides of abrasive material are identical with the side view of matrix, described abrasive material include the first abrasive material, second Abrasive material, the second abrasive material covers on tack coat, and the first abrasive material covers on the first abrasive material.

Preferably, one end of substrate support tack coat is provided with groove, also includes netted strengthening layer, netted strengthening Layer be embedded in matrix upper groove, after netted strengthening layer is fixed on matrix, netted strengthening layer be positioned at matrix with Between tack coat.

Preferably, described netted strengthening layer uses the steel wire of flat to work out..

Preferably, the mesh on described sealing coat intersects with the mesh of netted strengthening layer.

Have employed such scheme, due to the width of one end of substrate support tack coat, less than this matrix other end Width, two sides of matrix are inclined-plane or arcwall face, tack coat cover on matrix, abrasive material covers After covering on tack coat, tack coat is identical with the side view of matrix with the two of abrasive material sides.During work, When workpiece contacts with abrasive band, the side of abrasive material is inclined-plane or arcwall face, and workpiece is formed by the side of abrasive material The effect stepped down, not only will not defective work piece, the side in abrasive band also will not be worn in turn, abrasive band Life-span extended, thus processing cost significantly reduces.It addition, the first abrasive material covers at tack coat On, the second abrasive material covers on the first abrasive material.Described first abrasive material is corase grind layer, the second abrasive material For fine grinding layer.In the course of processing, the first abrasive material carried out corase grind to workpiece and cut before this, the first abrasive material by the time After layer makes to be finished, then by the second abrasive material, workpiece is carried out fine ginding, for the workpiece of polishing class, have It is beneficial to increase the fineness of workpiece, and not and change abrasive band, beneficially economization process time.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

With specific embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Seeing Fig. 1, New Abrasive Belt of the present utility model, including matrix 1, tack coat 2 and abrasive material, matrix 1 is fixed with abrasive material by tack coat 2.The thickness of matrix 1 is 2 10mm, and this thickness is preferably 5mm, Matrix 1 is soft material, such as kraft paper or latex paper.Described matrix 1 supports an end group of tack coat 2 The width of body, less than the width of this matrix 1 other end, two sides of matrix 1 are inclined-plane or arcwall face, Tack coat 2 covers on matrix 1, after abrasive material 3 covers on tack coat 2, and tack coat 2 and abrasive material 4 Two sides identical with the side view of matrix.Described abrasive material includes the first abrasive material 3a, the second abrasive material Layer 3b, the second abrasive material 3b cover on tack coat 2, and the first abrasive material 3a covers at the first abrasive material 3b On.Described first abrasive material 3a is corase grind layer, and the second abrasive material 3b is fine grinding layer.Abrasive material can be Jin Gang Stone is expected, it is also possible to be the abrasive materials such as carborundum, boron carbide or boron nitride.

Also including netted strengthening layer 4, after netted strengthening layer 4 is fixed on matrix 1, netted strengthening layer 1 is positioned at Between matrix 1 and tack coat 2, netted strengthening layer 4 is by being bonded and fixed on matrix 1.On matrix 1 Being provided with the groove embedded for netted strengthening layer 4, the degree of depth of this groove steel is less than the thickness of netted strengthening layer 4, Therefore, a part for netted strengthening layer 4 can be embedded in groove, and the other end is exposed at the outside of matrix 1, After matrix 1 bonds with netted strengthening layer 4, this structure can make the combination of netted strengthening layer and matrix 1 more Add firmly, and owing to the groove on matrix 1 is shallower, do not interfere with the self-strength of matrix 1.Due to Netted strengthening layer 4 is netted, in the course of the work.Preferably, described netted strengthening layer 4 uses flat The steel wire of shape is worked out, and the steel wire of this flat increases and the contact area of matrix 1, the most right Matrix 1 forms protection.
