Abstract

The utility model relates to a novel sand tray with a basal body. The sand tray comprises the basal body. A composite layer is disposed on the basal body in connecting mode. Through holes are respectively disposed at the centers of the basal body and composite layer. A polishing layer is disposed on the composite layer in connecting mode. The internal diameter of the polishing layer is bigger than the external diameter of the through hole. The novel sand tray with the basal body has the advantages of good safety performance, no deformation and high durability.

Description

New mold base emery disc

Technical field

The utility model relates to a kind of grinding field, particularly a kind of new mold base emery disc.

Background technology

The emery disc of present domestic employing is generally the red steel paper emery disc, and promptly matrix is a red steel paper, and red steel paper can change the characteristic of red steel paper according to the difference in season, and promptly winter, the red steel paper emery disc was because dry; The red steel paper emery disc can hardening, and is relative when summer, and the red steel paper emery disc can the moisture absorption, thereby makes the toughness of red steel paper emery disc to reduce greatly; Be the emery disc cracking, the form that adds glass fiber mesh in the middle of a lot of producers are employed in improves the toughness of emery disc, but this glass fiber mesh can produce a lot of dusts in bruting process; And symptom that the polishing personnel can take place that body is itched etc., and this red steel paper emery disc is when carrying out 90 ° of destructive polishings, and red steel paper is easy to crack; Because the red steel paper flintiness is very high, when polishing, red steel paper can burst out with the form of splashing; Be easy to human body is produced injury, and the red steel paper emery disc is when turning round test, when reaching 22000 rev/mins; Emery disc just can be out of shape, and is valgoid, and influence is used.

Summary of the invention

The purpose of the utility model is in order to overcome above deficiency, to provide a kind of security performance good, can not be out of shape, new mold base emery disc and production method thereof that durability is high.

The purpose of the utility model realizes through following technical scheme: a kind of new mold base emery disc; Said emery disc comprises matrix; Be connected with composite bed on the matrix; Matrix and composite bed center are equipped with through hole, and the circumferential edge of composite bed upper edge composite bed is connected with the polishing layer of ring-type, and the internal diameter of polishing layer is greater than the external diameter of through hole.

The further improvement of the utility model is: the aperture of said through hole is 16mm or 22mm, and composite bed is 125～180mm with the external diameter of polishing layer, and the width d of the polishing layer of ring-type is 30～40mm.

The further improvement of the utility model is: said composite bed is made up of the multilayer neutralizing layer.

The further improvement of the utility model is: said composite bed is made up of two-layer neutralizing layer.

The utility model compared with prior art has the following advantages: emery disc has elasticity, can carry out the plucking polishing, and security performance is high; Emery disc can be done 90 ° of destructive polishings, and brown crudefiber crop is compositely suppressed to form because composite bed is an organic fiber, so emery disc can not ftracture; Can not be out of shape; More can not become fragile or deliquescing because of the weather reason, comparatively environmental protection of the ash that produces in the bruting process, and durability is higher.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 be among Fig. 1 A-A to structural representation;

Label among the figure: 1-matrix, 2-through hole, 3-composite bed, 4-polish the layer.

The specific embodiment:

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show a kind of embodiment of the new mold base emery disc of the utility model like Fig. 1 and Fig. 2, said emery disc comprises matrix 1, is connected with composite bed 3 on the matrix 1, and matrix 1 is equipped with through hole 2 with composite bed 3 centers; The circumferential edge of composite bed 3 upper edge composite beds 3 is connected with the polishing layer 4 of ring-type, and the internal diameter of polishing layer 4 is greater than the external diameter of through hole 2, and the aperture of through hole 2 is 16mm or 22mm, and composite bed 3 is 125～180mm with the external diameter of polishing layer 4; The width d of the polishing layer 4 of ring-type is 30～40mm, and composite bed 3 is made up of the multilayer neutralizing layer, and composite bed 3 is made up of two-layer neutralizing layer; Matrix 1 is cotton paper or cotton or other ganoid common paper, and composite bed 3 is an organic fiber, and organic fiber is brown bast-fibre; Emery disc has elasticity like this, can carry out the plucking polishing, and security performance is high; Emery disc can be done 90 ° of destructive polishings, and brown crudefiber crop is compositely suppressed to form because composite bed 3 is an organic fiber, so emery disc can not ftracture; Can not be out of shape, more can not become fragile or deliquescing, comparatively environmental protection of the ash that produces in the bruting process because of the weather reason; And durability is higher, and when emery disc turns round test, 25000 rev/mins of emery discs can not be out of shape.
