Description
Technical field
The utility model relates to sand sponge technical fields, specifically, being related to a kind of sponge sand lump.
Background technique
Sponge sand lump is also known as sponge sanding block, polishes abrading block, resin grinding block, abrasive material abrading block, plastics abrading block etc..It is with sponge
For matrix, a kind of sanding and polishing material of upper abrasive sand is planted on sponge.It, can be with because its sponge matrix has water imbibition
Wet-milling is carried out, and can be bent, so receiving wide application.
However sponge sand lump is in use, the workpiece surface that the abrasive material and needs of sponge sand lump are polished carries out friction production
Powder is born, powder can follow the continuation of sponge sand lump to rub in workpiece surface, can cause to scratch to abrasion workpiece surface.
Utility model content
The purpose of this utility model is to provide one kind not will cause the sponge sand lump scratched to workpiece surface.
Technical solution used by sponge sand lump disclosed by the utility model is:
A kind of sponge sand lump, sponge matrix layer, substrate layer, primer layer, complex layer and abrasive material, the sponge matrix layer
Several grooves are offered, setting is spaced between the groove and groove, the substrate layer is set to the groove of sponge matrix layer
Interior, the substrate layer thickness is higher than the depth of groove, and the abrasive material sticks at substrate layer surface, the re-glue by primer layer
Layer covering and primer layer surface.
Preferably, the groove shapes are V-shape structure.
Preferably, the groove is configured according to certain interval.
Preferably, the recess width is greater than the interval width between groove and groove.
Preferably, the abrasive material is silicon carbide abrasive, brown corundum abrasive, fused alumina zirconia abrasive material, white fused alumina abrasive material
Or quartz sand abrasive material is made.
The beneficial effect of sponge sand lump disclosed by the utility model is: sponge matrix layer opens several equipped with groove, substrate
Layer is arranged in the groove, and by substrate layer protrusion and sponge matrix layer, the surface of substrate layer is equipped with abrasive material, which exists
In use, abrasive material and workpiece surface carry out contact polishing, the clast generated during the grinding process is broken under the promotion of substrate layer
Bits enter in the interval between groove, prevent clast from will not carry out two to workpiece surface between abrasive material and workpiece surface
Secondary friction, causes workpiece surface to scratch, and reduces unnecessary loss.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model sponge sand lump.
Fig. 2 is the cross-sectional view of the utility model sponge sand lump.
Fig. 3 is the enlarged drawing that A goes out in Fig. 2.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of sponge sand lump, sponge matrix layer 10, substrate layer 11, primer layer 12, complex layer
13 and abrasive material 14, sponge matrix layer 10 offer several grooves, carried out between groove and groove according to certain interval
Setting, and recess width is greater than the interval width between groove and groove, can guarantee that substrate layer 11 has certain width.
Substrate layer 11 is set in the groove of sponge matrix layer 10, and 11 thickness of substrate layer is higher than the depth of groove, abrasive material
14 stick at 11 surface of substrate layer, the covering of complex layer 13 and 12 surface of primer layer by primer layer 12, due to the thickness of substrate layer 11
Degree is higher than the depth of groove, therefore the protrusion of substrate layer 11 and sponge matrix layer 10.Abrasive material 14 and workpiece surface carry out when polishing
Contact polishing, under the promotion of substrate layer 11, clast enters in the interval between groove the clast generated during the grinding process.
Substrate layer 11 can be attached with sponge matrix layer 10 by interference fit, so as on 11 surface of substrate layer
Abrasive material 14 long-time service be damaged after can be replaced, can also will have different abrasive material mesh numbers substrate layer 11
Layering setting is carried out, different polishing needs are met.
In above scheme, groove type shape is V-shape structure, can biggish increases when polishing, abrasive material 14 and workpiece
The contact area on surface meets the polishing demand of different workpieces.
In above scheme, polishing layer is silicon carbide abrasive, brown corundum abrasive, fused alumina zirconia abrasive material, white fused alumina abrasive material or quartz
Material is sanded to be made.
The utility model discloses a kind of sponge sand lumps: sponge matrix layer opens several equipped with groove, and substrate layer is set to
In groove, by substrate layer protrusion and sponge matrix layer, the surface of substrate layer is equipped with abrasive material, the sponge sand lump when in use,
Abrasive material and workpiece surface carry out contact polishing, and under the promotion of substrate layer, clast enters the clast generated during the grinding process
Into the interval between groove, prevent clast from will not carry out secondary friction to workpiece surface between abrasive material and workpiece surface,
Cause workpiece surface to scratch, reduces unnecessary loss.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
