Abstract

The utility model relates to the technical field of equipment for grinding and processing hard fragile materials, particularly to a segmental block type diamond abrasive wheel. The utility model provides the segmental block type diamond abrasive wheel to overcome the problems of easy damage, limiting specification, raw material and energy source wasting and large workload of operators existing in the prior art. For overcoming the problems existing in the prior art, the utility model has the technical scheme that the segmental block type diamond abrasive wheel comprises a basal body and an external diamond grinding layer. The segmental block type diamond abrasive wheel is characterized in that the grinding layer is welded on the basal body and evenly divided into 2 to a plurality of grinding blocks along a peripheral direction.

Description

The multi-block type diamond-impregnated wheel

Affiliated technical field:

The utility model relates to hard brittle material is carried out the grinding equipment technical field, is specifically related to a kind of multi-block type diamond-impregnated wheel.

Background technology:

The raising that living environment and material progress is required along with fast development of society and people, a large amount of vehicle glass and glasswares have entered huge numbers of families, these glass articles for use all must be processed and grinding, for the diamond-impregnated wheel that grinding glass uses particularly most important.

Traditional diamond-impregnated wheel is made of matrix and outside diamond grinding layer, and the diamond grinding layer is provided with the geometry grinding face.Its preparation method is matrix to be put into the mould of steel, and then carries out the filler compacting.Behind the disposal molding, again with the mould that is connected as a single entity and emery wheel is put in the chamber type electric resistance furnace or the high-frequency induction heating coil in carry out high temperature sintering, then take out cooling mould unloading, each size of fine finishining diamond-impregnated wheel then.

The problem that prior art exists is: 1, fragile: because employing is whole pressing process, the density of the working lining of diamond-impregnated wheel and sintering temperature do not reach desirable requirement, can cause diamond grinding layer diamond particles in grinding process to come off easily, cause arc groove or typing work nest abrasion deformation on it, do not reach very high grinding linear meter and will more renew wheel.After manufacturer buys such product, not only incured loss through delay production task, but also strengthened the grinding expense of glass, increased production cost, especially all adopt under the situation of computer program controlled paddle-type mill in present each big glass grinding enterprise, its wearing and tearing are more serious, the use of the inapplicable current glass grinding processing industry of existing structure; 2, specification is limited: because disposal molding, to die needed and specification requirement agglomerating plant is very big, also need drop into a large amount of manually simultaneously, therefore can't make the diamond-impregnated wheel of the above big specification of Φ 400mm now; 3, waste raw material and the energy: because this structure needs disposal molding, therefore on the make both wasted a large amount of high-quality mould steel, and expended a large amount of electric power energies again; 4, operating personnel's workload is big: on the make Ben Chong mould need often move, and has strengthened heavy manual labor.

Summary of the invention:

The utility model will provide a kind of multi-block type diamond-impregnated wheel, with overcome that prior art exists fragile, specification is limited, waste raw material and the energy and the big problem of operating personnel's workload.

For overcoming the problem that prior art exists, the technical solution of the utility model is: the multi-block type diamond-impregnated wheel, comprise matrix 2 and outside diamond grinding layer, its special character is that described grinding layer is welded on the matrix and along the circumferential direction is divided into 2～N grinding block 1.

Be provided with bosh 3 between the above-mentioned grinding block 1.

Be provided with cooling bath 4 corresponding to bosh 3 on the excircle of above-mentioned matrix 2.

Above-mentioned grinding layer is divided into four grinding blocks 1.

Compared with prior art, the utility model has the advantages that:

1, not fragile: adopt monolithic sintered technology, improve the packing of material, therefore not fragile;

2, specification limit is big: can make the diamond-impregnated wheel of Φ 50mm to Φ 600mm;

3, save the mould raw material and the energy: do not adopt the drawing method of punching block, saved the expense of a large amount of steel and processing mold; Carry out sintering without resistance furnace or high-frequency induction heating coil, saved a large amount of electric power energies;

4, during the grinding layer piecemeal is made, can be directly the working face sintering of grinding block be pressed into multiple geometries such as V-type, U type, ladder type, duckbilled tongue type.Not only save a large amount of refine time and expense, but also saved valuable diamond;

5, reduced heavy manual labor:, therefore reduced working strength because the mould therefor size is little;

6, reduced the grinding cost of enterprise: the utility model can high efficiencyly be used to carry out glass grinding processing, and disposable grinding can reach more than 8000 linear meters.Grinding quality is better than product, the especially emery wheel that 200/230 fine-granularity diamond is made of the U.S. and Japan, and linear meter that reaches and grinding quality are more superior;

7, improve grinding quality: the tank of setting more can make emery wheel fully be cooled off in high-speed grinding, effectively improves grinding quality.

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2;

Fig. 3 is the schematic diagram of grinding block.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is elaborated.

Embodiment 1, and referring to Fig. 1 and Fig. 3, a kind of multi-block type diamond-impregnated wheel comprises matrix 2 and outside diamond grinding layer, and said grinding layer is welded on the matrix 2 and along the circumferential direction is divided into four grinding blocks 1.

Embodiment 2, referring to Fig. 2 and Fig. 3, a kind of multi-block type diamond-impregnated wheel, comprise matrix 2 and outside diamond grinding layer, said grinding layer is welded on the matrix 2 and along the circumferential direction is divided into four grinding blocks 1, be provided with bosh 3 between the said grinding block 1, on the excircle of matrix 2, be provided with cooling bath 4 corresponding to bosh 3.

Grinding layer is provided with V-type, U type, plane, goes up how much common grinding shapes such as circular arc type, following circular arc type and ladder type.

Preparation method of the present utility model is to comprise the steps: successively

(1) according to the specification of diamond-impregnated wheel, sinters the ring-type grinding layer that should be provided with on it into four grinding blocks 1 with Mold Making and in graphite jig;
