Abstract
The utility model provides a vulcanized fiber sand tray, belongs to the mechanical technical field and solves the problems of high noises and poor heat dissipation effect of the conventional vulcanized fiber sand tray. The vulcanized fiber sand tray comprises a base body provided with an installation hole and a grinding layer arranged on one surface of the base body, the grinding layer is provided with gradually extending curve slots and through holes penetrating through the grinding layer and the base body; and the center of the base body surrounds the installation hole and protrudes outwards to form a protruding part. The vulcanized fiber sand tray has the advantages of simplicity in structure, excellent heat dissipation effect and small noise.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of emery disc, particularly a kind of vulcan fibre emery disc.
Background technology
At present emery disc is adopted is with adhesive abrasive material to be sticked on the matrix that rag paper makes; The characteristic of rag paper itself is more crisp, and meeting be connected insecure with tracker action, damages easily; Emery disc can cause very big noise in use; The slag of grinding bits fly everywhere, and long-time use also can cause the emery disc surface temperature to raise, and high temperature can be to a series of bad chain reactions such as sand table body and vulcan fibre damage.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of simple in structure, good heat dissipation effect, vulcan fibre emery disc that noise is little.
The purpose of the utility model can realize through following technical proposal: a kind of vulcan fibre emery disc; Comprise matrix with installing hole and the grinding layer that is arranged on the matrix one side; It is characterized in that; Offer the open-work of gradually stretching curved grooves and through feed grinding layer and matrix on the described grinding layer, described matrix centre forms protuberance around the outside projection of installing hole.
In above-mentioned vulcan fibre emery disc, evenly offer a plurality of ditches hole on the described protuberance.
In above-mentioned vulcan fibre emery disc, described matrix adopting elastomeric material is processed.
In above-mentioned vulcan fibre emery disc, the described curved grooves of gradually stretching has 12～40.
In above-mentioned vulcan fibre emery disc, described open-work has 8～20.
Compared with prior art, on this vulcan fibre emery disc open-work is arranged, so binding agent not only spreads upon the surface of the matrix bonding abrasive material that gets on; And binding agent and abrasive material be extruded into the inwall of open-work again, makes abrasive material and matrix increase bonding point, therefore combines more firm; Abrasive material is difficult for breaking away from from matrix, thereby prolongs the service life of emery disc, open-work with gradually stretch curved grooves and match; Make aerodynamic profile change the noise in the time of obviously to reduce grinding.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, matrix 11, installing hole; 12, protuberance 13, ditch hole 2, grinding layer 21, gradually stretch curved grooves 3, open-work.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1, this vulcan fibre emery disc comprises matrix 1 with installing hole 11 and the grinding layer 2 that is arranged on matrix 1 one side, and matrix 1 adopts elastomeric material to process.
On grinding layer 2, offer the open-work 3 of gradually stretching curved grooves 21 and through feed grinding layer 2 and matrix 1, gradually stretching curved grooves 21 quantity is 12～40, and open-work 3 quantity are 8～20, and in the present embodiment, gradually stretching curved grooves 21 has 19, and open-work 3 has 12.Matrix 1 centre forms protuberance 12 and on protuberance 12, evenly offers a plurality of ditches hole 13 around installing hole 11 outside projections.
Open-work 3 is arranged on this vulcan fibre emery disc, so binding agent not only spreads upon the surface of the matrix 1 bonding abrasive material that gets on, and binding agent and abrasive material have been extruded into the inwall of open-work 3 again; Make abrasive material and matrix 1 increase bonding point, therefore combination is more firm, and abrasive material is difficult for breaking away from from matrix 1; Thereby prolong the service life of emery disc; Open-work 3 matches with gradually stretching curved grooves 21, makes aerodynamic profile change the noise in the time of obviously reducing grinding.
