The utility model discloses a net cloth is as the substrate of the wheel body of throwing emery wheel, and net cloth is meshed for there is a large amount of spaces (mesh 130 of each layer net cloth 100 self has formed the space 300 of wheel body; mesh 130 of adjacent net cloth is linked together and has also formed the space 300 of wheel body) in the wheel body inside and surface, and the shape of the mesh of this net cloth is not limited, can be quad slit, multilateral hole etc.. The polishing and grinding wheel made of the mesh cloth has larger and more gaps, better heat dissipation in the grinding process and reduced probability of burning of the workpiece; the grid cloth is provided with the meshes, and the wheel body is provided with the gaps, so that certain rigidity and elasticity can be brought in the grinding process, and the cutting can be more smooth; and because the grid cloth is provided with the meshes, the wheel body is provided with the gaps, and the grinding materials are adhered in the meshes, the grinding materials are adhered in the gaps, and the wheel body forms a three-dimensional sawtooth grinding structure, the grinding sharpness can be improved, and the grinding capacity of the polishing wheel can be improved. The grinding material 200 is adhered to each layer of the grid cloth 100, and the plurality of layers of the grid cloth 100 are bonded and cured to form the wheel body in an integrated structure, so that most of the wheel body can be utilized to participate in grinding operation, the grinding residual parts of the corresponding wheel body are less, and the wheel body is fully used. The utility model discloses a wheel body is makeed into with net cloth to the mode of bonding solidification, makes the wheel body inlayer abrasive material density even (in other words, the abrasive material can be more even distribute in the wheel body), consequently, the outer net cloth structure wearing and tearing back of wheel body, inlayer net cloth structure can produce the grinding effect the same with skin. In any layer of the mesh cloth 100, at least part of the meshes are not blocked, so that gaps can be effectively formed between the inner part of the wheel body and the surface, and preferably, in any layer of the mesh cloth 100, all the meshes are not blocked; specifically, the mesh of any one layer of the mesh cloth is not blocked by the abrasive on the layer of the mesh cloth, but there may be a case where the mesh cloth is blocked (not blocked) by the abrasive on the adjacent layer of the mesh cloth. The meshes of the mesh cloth 100 are obvious and regular; the mesh 130 is distributed in an array on the grid cloth 100. Alternatively, each of the sheets 100 may have an abrasive material 200 attached to one or both of the surfaces.

Further, as shown in fig. 15, the mesh holes 130 of each layer of the mesh cloth are communicated with the mesh holes 130 of the adjacent mesh cloth to form a gap 300 of the wheel body, and the abrasive material 200 is attached to the gap 300. That is, the mesh holes 130 of each layer of mesh cloth form the wheel body void space 300; the openings 130 of adjacent meshes are connected to form the gap 300 of the wheel body. The wheel body has a void 300 in both the interior and the surface.

Further, as shown in fig. 15, for the abrasive material 200 attached to any one layer of the grid cloth 100, a part of the abrasive material 200 is located in the mesh 130 of itself, a part of the abrasive material 200 is located at the mesh 130 of the adjacent grid cloth, and a part of the abrasive material 200 is located between the lines of the adjacent grid cloth 100. For portions of the abrasive material 200 located at the mesh 130 of adjacent grids, it is meant that: portions of the abrasive material 200 may be positioned on the inside of the mesh 130 of adjacent scrim or may be positioned on the outside of the mesh 130 of adjacent scrim, as shown in fig. 16.

Alternatively, the mesh openings 130 of adjacent meshes are aligned; alternatively, the mesh openings 130 of adjacent meshes are staggered. This design includes four embodiments, the first being that all of the mesh 130 of the scrim are aligned; secondly, all the meshes 130 of the mesh cloth are staggered; thirdly, all the meshes 130 of the adjacent meshes are staggered, and the meshes 130 of the non-adjacent meshes can be aligned; the fourth is that in all the adjacent grids, the meshes 130 of some adjacent grids are aligned, and the meshes 130 of some adjacent grids are staggered. Among the four implementation manners, the first implementation manner can maximize the mesh hole space of the wheel body, and the space of the wheel body can penetrate through two end faces of the wheel body, so that the heat dissipation effect of the polishing wheel is improved, and the polishing wheel is more smoothly arranged and cut. The similarity of the second, third and fourth types is larger, and the meshes 130 of the adjacent gridding cloth are staggered, so that the abrasive materials attached to the gridding cloth lines are positioned at the meshes of the adjacent gridding cloth, more abrasive materials are exposed in the gaps of the wheel body, and the grinding capacity of the polishing and grinding wheel can be improved.

Further, as shown in fig. 14 and 15, the abrasive 200 is attached to the lines of the mesh cloth 100. The utility model discloses a wheel body 500 of emery wheel is thrown to net, the abrasive material is on being attached to the lines of net cloth 100, and the abrasive material also is difficult for droing, and net cloth 100 just is equivalent to exactly the skeleton of wheel body 500. As the abrasive 200 is attached to the lines of the grid cloth 100, as shown in fig. 14b and c, for any layer of grid cloth, the line segments between two adjacent meshes of the grid cloth are attached with the abrasive, so that a large number of line segments attached with the abrasive are formed in the grid cloth, similar to the fact that a large number of "small abrasive belts (or small abrasive lines)" fixed at two ends exist in the polishing wheel, when the polishing wheel is used for grinding, the workpiece is ground by the large number of "small abrasive belts" from all directions, and the grinding capacity of the polishing wheel can be improved. The lines of the grid cloth 100 are basic units constituting the grid cloth, and it is easily understood that, for example, the grid cloth includes warp threads 110 and weft threads 120, and the warp threads 110 and the weft threads 120 are interwoven to form the grid cloth 100 with the mesh holes 130; the warp 110 and the weft 120 are lines of the mesh fabric 100. The mesh cloth 100 may be a plain weave mesh cloth or a twisted weave mesh cloth, or other woven cloth in a braided form. The plain-woven mesh fabric, as shown in fig. 12, includes warp threads 110 and weft threads 120, the warp threads and the weft threads are interlaced, so that the mesh fabric with mesh holes is formed by plain weaving, and the lines of the mesh fabric 100 are the warp threads 110 and the weft threads 120 of the plain-woven mesh fabric. The leno weaving mesh fabric, as shown in fig. 13, comprises warp threads 110 and weft threads 120, wherein the warp threads 110 comprise a warp thread 111 and a ground thread 112, the warp thread and the ground thread are twisted with each other and are interwoven with the weft threads, so that the leno weaving forms a mesh fabric with meshes, between the adjacent weft threads 120, the warp thread 111 and the ground thread 112 are twisted with each other to form a twisted part 113, the weft threads 120 are clamped by the warp thread 111 and the ground thread 112, and the threads of the mesh fabric 100 are the warp thread 111, the ground thread 112 and the weft threads 120 of the leno weaving mesh fabric. FIG. 14a is a schematic diagram of a prior art dense cloth substrate after being implanted with an abrasive, FIG. 14b is a schematic diagram of a plain-weave grid cloth of the present invention after being implanted with an abrasive, and FIG. 14c is a schematic diagram of a twisted grid cloth after being implanted with an abrasive; it can be seen that if a dense cloth base (such as paper, vulcanized paper, woven cloth, non-woven cloth, composite matrix or film) of the prior art is used as a base material for the polishing wheel, the abrasive can be implanted only into the surface of the base material; and adopt the utility model discloses a when net cloth was as the substrate of throwing the emery wheel, the abrasive material can be implanted the surface of substrate and mesh in, on the lines of adhering to net cloth 100. Preferably, the cross-sectional areas of the warp threads 110 and the weft threads 120 are substantially equal, and the warp threads 110 and the weft threads 120 are made of the same material.

Optionally, the grid cloth 100 is a woven cloth made of one or more fiber materials selected from hemp fiber, cotton fiber, nylon fiber, paper fiber, glass fiber, basalt fiber, carbon fiber, polyester fiber, polyethylene fiber, magnesium chloride fiber, acrylic fiber, aramid fiber, acetate fiber, viscose fiber, dog hair fiber, horse hair fiber, pig hair fiber, and wool fiber.

Further, as shown in fig. 15, the abrasive material 200 is attached to each layer of the mesh cloth 100 by an adhesive layer 400, and the plurality of layers of the mesh cloth 100 are bonded and cured by the adhesive layer 400 to form the wheel body 500. When the abrasive material is combined in any layer of the grid cloth 100, and at least part of the meshes are not blocked, the meshes of the grid cloth are not blocked by the abrasive material on the layer of the grid cloth, and certainly not blocked by the adhesive layer 400.

The utility model discloses a wheel body of emery wheel is thrown to net has the dual characteristics of coating grinding apparatus and consolidation grinding apparatus. Coated abrasives are those in which an abrasive is adhered to a flexible substrate by a binder, also known as a flexible abrasive. Bonded abrasives are tools made of abrasive material (grinding material) and a binder having a certain shape and a certain grinding ability. In the wheel body of the grid polishing wheel of the utility model, the grinding material 200 is attached to each layer of grid cloth 100 through the adhesive layer 400, which is similar to the form of a flexible grinding tool; the layers of mesh cloth 100 are bonded and cured by the adhesive layer 400 to form the wheel body 500, which is similar to a form of a bonded abrasive tool. The abrasive cloth in the background art is a typical flexible abrasive tool, and the abrasive cloth wheel is an extension product of the abrasive cloth; the resin wheel of the background art is a typical bonded abrasive tool.

Compared with the abrasive cloth wheel, the grid polishing wheel of the utility model basically has the advantages that the abrasive materials are more dense closer to the center of the abrasive cloth wheel, and the abrasive cloth wheel is harder closer to the center of the abrasive cloth wheel, so that the grinding capacity is poor; and the utility model discloses a grinding material of net throwing grinding wheel can be more even distribute in the wheel body (have the advantage of consolidation grinding apparatus). Compared with an abrasive cloth wheel, the abrasive material distribution is more uniform, the grinding performance is stable, the performance is stable, and the grinding wheel has stronger grinding capacity, heat dissipation capacity and chip removal capacity.

Compared with the resin grinding wheel, the grid polishing wheel of the utility model has the advantages that the grinding materials of the resin grinding wheel are bonded with each other, in the grinding process, part of the grinding materials can fall off after failing to participate in the grinding process, the proportion of the grinding materials in the resin grinding wheel is large, and the consumption of the grinding materials is large; the grinding material 200 of the grid polishing wheel of the utility model is attached to the grid cloth 100 (which has the characteristics of a coated grinding tool), so that the grinding material is not easy to fall off, the proportion of the grinding material in the grid polishing wheel is relatively small, and the grinding material can be saved; compared with a resin grinding wheel, the grinding material is not easy to fall off, has stronger grinding capacity, heat dissipation capacity and chip removal capacity, and has certain rigidity and elasticity.

Compared with the adhesive cloth wheel, the grid polishing wheel of the utility model has the advantages that after the abrasive material on the surface of the adhesive cloth wheel is consumed, the abrasive material needs to be coated with adhesive sand again and then is used continuously, and the grid polishing wheel is used repeatedly, so that the grid polishing wheel is troublesome and difficult to realize continuous grinding operation; and the utility model discloses a grinding material of emery wheel is thrown to net distributes in the wheel body, can continuation carry out the grinding operation.

Alternatively, as shown in FIG. 15, a portion of the abrasive material 200 is exposed to the adhesive layer 400; alternatively, the entirety of abrasive material 200 is surrounded by adhesive layer 400. When a part of the abrasive 200 is exposed out of the adhesive layer 400, the abrasive 200 can directly participate in grinding, so that the grinding sharpness of the grinding working surface of the wheel body can be increased, and the grinding efficiency can be improved. When the grinding material 200 is completely wrapped by the adhesive layer 400, the adhesive layer 400 wrapped outside the grinding material is instantly worn during grinding operation, and the grinding material can expose the adhesive layer 400, so that the grinding sharpness and the grinding efficiency of the grinding working surface of the wheel body are not affected basically. That is, no matter a part of the abrasive material 200 is exposed out of the adhesive layer 400, or the whole abrasive material 200 is wrapped by the adhesive layer 400, the wheel body has good grinding ability, and the difference of the use effect of the two schemes is not obvious. In the actual manufacturing process of the polishing wheel, the abrasive material 200 is mostly wrapped by the adhesive layer 400, and of course, a part of the abrasive material 200 is exposed from the adhesive layer 400. That is, in the wheel body, a part of all the abrasives may be exposed out of the adhesive layer 400; or all of the abrasives are wrapped by the adhesive layer 400; it is also possible that some of the abrasives are partially exposed by the adhesive layer 400 and other abrasives are entirely covered by the adhesive layer 400. This is all within the scope of the present invention.

Further, the adhesive layer 400 contains reinforcing chopped fibers or/and whiskers for reinforcing the mechanical properties of the mesh cloth. For a wheel-shaped grinding tool, in the process of high-speed rotation of the grinding tool, a base material of the grinding tool is subjected to a larger centrifugal force, so that the mechanical property of the base material needs to meet the use requirement, and particularly the base material needs to have stronger tensile capacity; compared with the grid cloth with obvious meshes in the same material specification and a compact cloth base (such as paper, vulcanized paper, woven cloth, non-woven cloth, a composite matrix or a film) without meshes or obvious meshes, the tensile capacity of the grid cloth is obviously lower than that of the compact cloth base; therefore, the wheel body made of the mesh cloth can improve the grinding capacity, the heat dissipation capacity and the chip removal capacity and simultaneously sacrifice part of tensile capacity; when the rotating speed of the grinding tool is extremely high, the grinding tool with the mesh cloth as the base material is likely to break, so that potential safety hazards are caused, and the maximum rotating speed which can be reached by the grinding tool is limited. Therefore, the utility model provides a contain the design that is used for strengthening the enhancement mode chopped strand fibre of the mechanical properties of net cloth or/and whisker in adhesive layer 400, can improve the mechanical properties of net cloth and net throwing emery wheel body, especially tensile ability, avoid appearing the condition that the net throws the emery wheel and breaks, improved the security that the net throws the emery wheel. The reinforced chopped fiber can be one or a mixture of chopped basalt fiber, chopped glass fiber and chopped carbon fiber; preferably, the reinforcing chopped fibers are chopped basalt fibers. The crystal whisker can be one or a mixture of more of calcium sulfate crystal whisker, calcium carbonate crystal whisker, aluminum oxide crystal whisker, zinc oxide crystal whisker and silicon carbide crystal whisker; preferably, the whiskers are calcium sulfate whiskers. The mesh fabric is a woven fabric (such as plain weave mesh fabric or twisted mesh fabric), and when the design that the adhesive layer 400 contains the whiskers is adopted, the whiskers can penetrate into the warps and wefts of the mesh fabric, particularly can be adsorbed at the intersection of the warps and wefts of the mesh fabric to form a multi-point bonding structure microscopically, and can also avoid slippage between the warps and wefts of the mesh fabric because the whiskers are micro-nano short fibers. By adopting the design in which the adhesive layer 400 contains whiskers, the grinding ratio (the ratio of the amount of material removed from the workpiece to the amount of wear of the polishing wheel) can be increased.

Preferably, the mechanical properties of the mesh fabric 100 in the warp direction and the weft direction are substantially the same. The warp direction of the mesh fabric 100 refers to the longitudinal direction of the warp of the mesh fabric 100, and the weft direction of the mesh fabric 100 refers to the longitudinal direction of the weft of the mesh fabric 100.
