Description

Double net cymbal type grindings

Technical field

The utility model relates to be ground field more particularly to the grinding of double net cymbal types.

Background technique

Grinding is most important one kind grinding tool in grinding；Grinding is that bonding agent is added in abrasive material, through green compact, is done It is dry and roasting and manufactured porous body；Current grinding needs to increase mesh sheet in grinding in production, to improve the strong of grinding Degree；But current mesh sheet structure is relatively simple, and has certain thickness and weight, reduces the dosage of abrasive material, significantly Influence the service life and grinding effect of grinding.

Utility model content

The purpose of the utility model is to provide the double net cymbal types grindings for improving abrasive consumption.

The technical solution of the utility model is as follows：

Double net cymbal type grindings, including grinding ontology, which is characterized in that grinding ontology successively includes the first molding from top to bottom The bed of material, the first mesh sheet, the second molding bed of material, the second mesh sheet and third form the bed of material；First, second mesh sheet by weft yarn and Warp thread weaves；The weft yarn includes a weft, and warp thread includes three warps.

The weft tiling setting.It is arranged since weft tiles, so that the forced area of weft is larger, so that stress is more equal It is even.

The weft width is 0.8mm-1.5mm.When weft width is 0.08mm, materials are minimum, and cost is minimum；Work as latitude When line width is 1.5mm, it is able to bear biggish active force.

The first, second, third molding bed of material is Brown Alundum and phenolic resin.Using Brown Alundum, grinding performance is good, at This is low.

The Brown Alundum purity is greater than 96%.Since its purity is higher, ground effect is effectively enhanced.

Brown Alundum accounts for 70% in the first, second, third molding bed of material, and phenolic resin accounts for about 20%.Due to phenolic aldehyde tree It is good that rouge accounts for about 20% viscosity, so that Brown Alundum is easier to bond together, good forming effect.

The guide groove of several arcs is offered on the outer surface of the grinding ontology two sides, the guide groove is to be ground in ontology Heart line is that the center of circle is evenly arranged on the outer surface of grinding ontology.Since the guide groove using arc understands some cooling in grinding Liquid is sprayed onto guide groove, and coolant liquid flows into the grinding side of grinding with guide groove；Since guide groove uses arc, arc area is larger, Some coolant liquid will not arrive at guide groove bottom, but the grinding side of grinding can be flowed directly into from guide groove side wall.

The utility model has the beneficial effects that：Due to braiding use a weft and three warps so that mesh sheet compared with Gently, material is saved, production cost is saved；And mesh sheet thickness is than relatively thin, and when abrasive wheel forming, the dosage of molding mass can With some more, abrasive grain rate is higher, and the performance of grinding wheel is relatively good.

Detailed description of the invention

Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will It becomes apparent.

Wherein：FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the first, second mesh sheet of the utility model structural schematic diagram；

Fig. 3 is the utility model guide barrel construction schematic diagram；

Fig. 4 is the first abrasive material of the utility model schematic diagram of a layer structure；

In attached drawing, 1 is grinding ontology, and 2 be the first molding bed of material, and 3 be the first mesh sheet, and 4 be the second molding bed of material, and 5 be the Two mesh sheet, 6 form the bed of material for third, and 7 be weft, and 8 be warp, and 9 be guide groove, and 10 be the first abrasive material, and 11 be the second abrasive material.

Specific embodiment

It is shown in Figure 1, double net cymbal types grinding, including grinding ontology 1, which is characterized in that grinding ontology from top to bottom according to Secondary includes the first molding bed of material 2, the first mesh sheet 3, second molding bed of material 4, the second mesh sheet 5 and the third molding bed of material 6；Described One, the second mesh sheet is woven by weft yarn and warp thread；The weft yarn includes a weft 7, and warp thread includes three warps 8.By A weft and three warps are used in braiding, so that mesh sheet is lighter, material is saved, saves production cost；And mesh sheet Thickness is than relatively thin, and when abrasive wheel forming, the dosage of molding mass can be some more, and abrasive grain rate is higher, and the performance of grinding wheel compares It is good；Due to using the three formable layer bed of materials, abrasive material used is more, and grinding dynamics is larger, and can polish biggish part, and is ground effect Fruit is preferable；Due to using two layers of mesh sheet, it can effectively ensure that the intensity of grinding, fly after avoiding grinding from bursting apart in use Out；Wherein the molding bed of material can be combined together with mesh sheet by green compact, drying and roasting.

The weft tiling setting.It is arranged since weft tiles, so that the forced area of weft is larger, so that stress is more equal It is even.

The weft width is 0.8mm-1.5mm.When weft width is 0.08mm, materials are minimum, and cost is minimum；Work as latitude When line width is 1.5mm, it is able to bear biggish active force.

The weft width is 1mm.When weft width is 1mm, in the case where guaranteeing the biggish situation of stress, materials are minimum.

The first, second, third molding bed of material is Brown Alundum and phenolic resin.Using Brown Alundum, grinding performance is good, at This is low.

The Brown Alundum purity is greater than 96%.Since its purity is higher, ground effect is effectively enhanced.

Brown Alundum accounts for 70% in the first, second, third molding bed of material, and phenolic resin accounts for about 20%.Due to phenolic aldehyde tree It is good that rouge accounts for about 20% viscosity, so that Brown Alundum is easier to bond together, good forming effect.

The guide groove 9 of several arcs is offered on the outer surface of the grinding ontology two sides, the guide groove is to be ground ontology Center line is that the center of circle is evenly arranged on the outer surface of grinding ontology.Since it is cold some in grinding for the guide groove using arc But liquid is sprayed onto guide groove, and coolant liquid flows into the grinding side of grinding with guide groove；Due to guide groove use arc, arc area compared with Greatly, some coolant liquid will not arrive at guide groove bottom, but the grinding side of grinding can be flowed directly into from guide groove side wall.

Described first, the third molding bed of material be alternately arranged by several first abrasive materials 10 and several second abrasive materials 11 and At；Molding bed of material outermost layer is the first abrasive material.Due to being used alternatingly using two kinds of abrasive materials, compared to being applied alone a kind of abrasive material to enhance Ground effect, and do not need entirely to be ground all using same material, the abrasive material used in this way is fewer can be used by from It produces other and is ground generated waste material, save production cost；Wherein the first abrasive material can use Brown Alundum, the second abrasive material White fused alumina or diamond can be used.

The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model System, it is all according to any simple modification to the above embodiments in the technical essence of the utility model, equivalent variations, fall Enter within the protection scope of the utility model.
