Abstract

The utility model relates to a vulcanized fiber paper grinding plate for enhancing noise abatement effect. The utility model comprises a base and a grinding layer arranged on the side of the base. A centre bore is positioned in the center of a grinding plate and an involute groove is on the grinding layer. The grinding plate is also equipped with a through-hole. The abrasive of the grinding plate increases bond points with the base for combining more firmly, thereby the abrasive is difficult to be separated from the base. So the service life of the grinding plate is prolonged. The grinding plate has the advantage of reducing noise while grinding.

Description

A kind of enhancing noise reduction vulcan fibre emery disc

Technical field

The utility model belongs to grinding tool, relates in particular to the emery disc that grinding is used.

Background technology

Usually emery disc is to be used for the grinding tool that the rusty scale of material surface, burr or unnecessary processing capacity are removed in grinding.

And traditional emery disc is with binding agent abrasive material to be sticked on the matrix that rag paper makes, and drying solidifies then again.During use, be installed on motor or the pneumatic angle grinding machine, in rotation, various materials are carried out grinding, because velocity of rotation reaches more than 80 meter per seconds during grinding, therefore it can send the thorn ear noise of 80-120 decibel when work, in the process of grinding, abrasive material is broken away from from matrix simultaneously, so the present emery disc life-span of using is shorter owing to vibrating.

Summary of the invention

The purpose of this invention is to provide a kind of emery disc that can reduce noise and long service life.

The present invention seeks to be achieved through the following technical solutions: this enhancing noise reduction vulcan fibre emery disc comprises matrix and is arranged on matrix grinding layer simultaneously that there is centre bore at the emery disc center, has gradually to stretch curved grooves, also is provided with open-work on this emery disc on grinding layer.

Grinding layer gradually stretch curved grooves, the 8-36 bar is arranged.

Strengthening the open-work that is provided with on the noise reduction vulcan fibre emery disc is 10-150.

Described open-work is for only penetrating the hole of matrix.

Described open-work is the through hole that penetrates matrix and grinding layer.

Owing on this emery disc open-work is arranged, so binding agent not only spreads upon the surface of the matrix bonded abrasive that gets on, and binding agent and abrasive material have been extruded into the inwall of open-work again, make abrasive material and matrix increase bonding point, therefore their combinations is more firm, abrasive material then is difficult for breaking away from from matrix, so can prolong the service life of emery disc.Through hole on the emery disc matches with the curve of gradually stretching on it, and aerodynamic profile is changed, the noise in the time of significantly reducing grinding.

The specific embodiment

Embodiment 1:

A kind of enhancing noise reduction vulcan fibre emery disc comprises matrix 1 and is arranged on matrix 1 grinding layer 2 simultaneously that there is centre bore 3 at the emery disc center, has gradually to stretch curved grooves 4 on grinding layer, the bar number of gradually stretching curved grooves is 26.Also be provided with open-work on this emery disc, this open-work is divided into two kinds, and a kind of hole is for only penetrating the hole 5 of matrix, and another kind of hole is the through hole 6 that penetrates matrix 1 and grinding layer 2; The quantity in hole 5 is 100, and the quantity of through hole 6 is 12.

Embodiment 2: in the present embodiment on the emery disc set open-work all be the through hole 6 that penetrates matrix 1 and grinding layer, the quantity of through hole 6 is 10; Other structures are identical with embodiment 1.

Embodiment 3: in the present embodiment on the emery disc set open-work all be the hole 5 that only penetrates matrix 1, the quantity in hole 5 is 150; Other structures are identical with embodiment 1.Emery disc in the present embodiment has increased the fastness of matrix 1 with grinding layer 2, but the emery disc among above two embodiment of erasure effect is poor.

Matrix 1 in the foregoing description is preferably selected the rag paper manufacturing for use, the hole 5 on the emery disc and the diameter of through hole 6 can be identical or different, total number of open-work can be selected any number between the 10-150 for use on the emery disc, if the quantity of the big open-work of the diameter of emery disc also can be provided with more than 150, the quantity in through hole 6 and hole 5 also can be selected arbitrarily as required.
