Description
Technical field
The utility model relates to a kind of emery wheel, belongs to grinding tool technical field.
Background technology
Emery wheel is a kind of more common bonded abrasive tool, is mainly used in cylindrical, inner circle, the plane of metal or non-metal workpiece and other profiles are roughly ground, half fine grinding and the operation such as fluting and cut-out.Emery wheel of the prior art is generally suppress after being mixed with adhesive by abrasive material to form, and its shape is a uniform disk of surface smoothing thickness, and centre perforate is to be arranged on the axle of High Rotation Speed.During work, the abrasive cut-off wheel of High Rotation Speed is contacted with workpiece to be machined, and applies certain pressure, thus produce friction, form the object of grinding.Emery wheel is after working long hours, and can produce high temperature because of friction, high temperature can cause emery wheel to be out of shape, impact polishing effect, and in addition, emery wheel is at High Rotation Speed, and in bruting process, if emery wheel breaks, its fragment splashes out at a high speed, is easy to hurt operator.Therefore, new technical scheme should be provided to solve the problem.
Summary of the invention
The utility model, just for above technical problem, provides a kind of emery wheel of rational in infrastructure, modified node method that result of use is good.
The utility model is achieved through the following technical solutions:
A kind of emery wheel of improvement, comprise emery wheel body, the medial surface of described emery wheel body is provided with metallic matrix, the center of described metallic matrix has the through hole be connected with abrasive machine, the outer surface of described emery wheel body is provided with the explosion-proof rete be cemented in by adhesive layer on emery wheel body outer surface, and described explosion-proof rete is made up of the rupture pressure disc basic unit on upper strata and the metal level be adsorbed on below rupture pressure disc basic unit.
Further, described metallic matrix is aluminum substrate.
Described rupture pressure disc basic unit is pet layer.
Described metal level is metallic aluminium, silver or nickel dam.
The surface of described emery wheel body is provided with many cross one another grooves, and many cross one another grooves form multiple grinding part on the surface of emery wheel body.
Connected by some connectors relative to through hole annular arrangement between described emery wheel body and metallic matrix.
Further, described connector is rivet.
Due to the employing of technique scheme, compared with prior art, tool has the following advantages the utility model:
The utility model emery wheel, structure is simple, and good stability, has explosion-proof performance simultaneously, and security is high, and the grinding part frictional force that emery wheel body surface is formed is strong, and ground effect is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
During it is: 1, emery wheel body, 2, metallic matrix, 3, rupture pressure disc basic unit, 4, metal level, 5, through hole, 6, connector, 7, grinding part.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the emery wheel of a kind of improvement of the utility model, comprises emery wheel body 1, and the medial surface of emery wheel body 1 is provided with metallic matrix 2, connected by some connectors 6 relative to through hole annular arrangement between emery wheel body 1 and metallic matrix 2, in the present embodiment for connector 6 for rivet.
The center of metallic matrix 2 has the through hole 5 be connected with abrasive machine, the outer surface of emery wheel body 1 is provided with the explosion-proof rete be cemented in by adhesive layer on emery wheel body outer surface, explosion-proof rete is made up of with the metal level 4 be adsorbed on below rupture pressure disc basic unit 3 the rupture pressure disc basic unit 3 on upper strata, described metallic matrix 2 is aluminum substrate, rupture pressure disc basic unit 3 is pet layer, and metal level 4 is the one in metallic aluminium, silver or nickel dam.Emery wheel of the present utility model, is provided with metallic matrix 2 at the medial surface of emery wheel body 1, its intensity is strengthened greatly, can extend its service life, reduces use cost.Be provided with explosion-proof rete at the outer surface of emery wheel body 1, even if it is cracked that emery wheel occurs, its fragment also can not splash out, improves the security that it uses.
Preferably, as an embodiment, the surface of emery wheel body 1 is provided with many cross one another grooves, many cross one another groove forms multiple grinding part 7 on the surface of emery wheel body, the shape of grinding part can for being triangle, other any shapes such as rhombus, the frictional force that grinding part produces is far longer than the frictional force formed between prior art medium plain emery wheel and workpiece to be machined, substantially increases grinding efficiency.
