Abstract
The utility model discloses a grinding disc which comprises an arch substrate, a mounting fixed hole arranged in the center of the substrate, an elastic groove arranged on the lateral side of the mounting fixed hole, vent holes arranged on the substrate, a reinforced mesh cloth layer compounded on the surface of substrate and a grinding material layer arranged on the reinforced mesh cloth layer. The grinding disc has reasonable structure, high bonding strength and can effectively prevent grinded work piece from being burned and has long service life.
Description
Technical field:
The utility model relates to a kind of grinding tool, is a kind of grinding emery disc.
Background technology:
Emery disc is generally used for grinding and removes material surface rusty scale, burr, weld seam or allowance.
Traditional emery disc heat of high temperature of grinding area generation in use can cause the adhesive performance to descend, and abrasive material comes off soon, and the emery disc life-span is short; The heat of high temperature that grinding area produces can cause being influenced the quality of workpiece by buffing work-piece surface high temperature burn; The dust that grinding area produces can stop up abrasive material, has reduced grinding efficiency, has shortened the service life of emery disc, and has caused easily by the buffing work-piece surface blackening; Fugitive constituent in the emery disc production process in the adhesive is difficult for volatilization fully, thereby causes the bond effect of adhesive to descend, and has shortened the service life of emery disc.
Summary of the invention
The purpose of this utility model provides a kind of adhesion strength height, can effectively prevent to be burnt by buffing work-piece the emery disc of long service life.
Technical solution of the present utility model is:
A kind of emery disc is characterized in that: comprise the arch matrix, the matrix center is provided with and installs and fixes the hole, installs and fixes hole arranged outside elastic groove, and matrix is provided with steam vent, and matrix surface is compounded with the enhancing scrim layer, strengthens scrim layer and is provided with abrasive material outward.
Steam vent has 1～150.Elastic groove has 2～6.
The utility model emery disc heat of high temperature of grinding area generation in use can be discharged by steam vent, has avoided high temperature to cause the adhesive performance to descend, and has avoided by buffing work-piece surface high temperature burn; The dust of grinding area can be discharged by steam vent, has avoided the emery disc abrasive material to stop up; The adhesive fugitive constituent can be discharged from steam vent in the emery disc production process, has improved the bond effect of adhesive; Adhesive can be penetrated into the inwall of steam vent in process of production, has increased the bonding point of abrasive material and matrix, and it is more firm to bond.Therefore this emery disc has grinding efficiency height, protection by the advantage of buffing work-piece, adhesive strength height, long service life.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the profile along the cylindrical center line.
The specific embodiment
Emery disc comprises matrix 4, strengthens screen cloth 3, abrasive material 2.Matrix 4 is made by vulcan fibre or plastics or glass fiber mesh, and matrix 4 is arch, and its center is provided with and installs and fixes hole 5 and elastic groove 6, and matrix 4 is provided with steam vent 1; The screen cloth 3 of enhancing is arranged between matrix 4 and the abrasive material 2, and the material that strengthens screen cloth 3 is glass fibre or nylon; Matrix 4 and abrasive material 2, screen cloth 3 are by adhesive bonds.
The matrix 4 of this emery disc is provided with steam vent 1, and quantity is 1-150.
Enhancing screen cloth 3 materials of this emery disc are glass fibre or nylon.
The position of the steam vent 1 in the present embodiment can be selected arbitrarily as required.
