Description

The high-rate grinding emery disc

Technical field

The utility model relates to a kind of grinding tool, relates to a kind of Grinding sand disc grinding tool specifically.

Background technology

Domestic traditional Grinding sand disc is the papery matrix (being the red steel paper matrix) through being processed into emery disc by cotton pulp or wood pulp at present, after being coated with the last layer primer on the red steel paper matrix, plant sand again, after preliminary baking and curing and typing, be coated with last layer glue and one deck sand again, a kind of Grinding sand disc of after drying and shaping is coated with adhesive curing again, making.This Grinding sand disc is mainly used in the rust cleaning of various metals (as the shipyard hull), grinding-polishing such as deburr at home, also can be used for the sanding and polishing of cement flooring.There is the production process complexity in traditional Grinding sand disc, matrix strength is low, the cost height, the security performance instability, protection against the tide or water resistance be poor, be not suitable for defectives such as outdoor work and submersible, and the low and security incident that the abrasive disc fragmentation flies out and hurts sb.'s feelings when polishing takes place of Chang Yinwei intensity, and with the matrix of processing such as cotton pulp paper pulp, seriously consumption of natural resource.

The utility model content

The purpose of this utility model provides a kind of simple in structure, high-rate grinding emery disc that intensity is high, safe and reliable.

For achieving the above object, technical solution adopted in the utility model is: the high-rate grinding emery disc is characterized in that it comprises matrix, reinforcing ring, grinding working lining; The middle part of matrix is provided with through hole, and the through hole of matrix is fixed with reinforcing ring; The front of matrix is provided with the grinding working lining of ring-type, and reinforcing ring is positioned at the inboard of grinding working lining; The material of matrix includes glass fibre or polyester-cotton blend.

The beneficial effects of the utility model are: 1, through hole is used to be positioned on the electric tool and uses, and adopts reinforcing ring to reinforce, and has the characteristics of intensity height, safe and reliable, long service life.

2, the material of matrix includes glass fibre or polyester-cotton blend, matrix have the intensity height, safe and reliable, centrifugal force resistant is strong, water-fast weather resistance is good, and with the characteristics of primer and abrasive material strong adhesion.

3, the utility model is simple in structure, manufacturing is simple, cost is low, and matrix and grinding working lining (abrasive material) synchronous consumption are good, grinding is sharp lastingly, grinding force is strong.

Description of drawings

Fig. 1 is structural representation of the present utility model (front view);

Fig. 2 is along the cutaway view of A-A line among Fig. 1;

Fig. 3 is the rearview of Fig. 1;

Among the figure: 1-matrix, 2-reinforcing ring, 3-grinding working lining, 4-through hole, 5-paper.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the high-rate grinding emery disc, it comprises matrix 1, reinforcing ring 2, grinding working lining 3; The middle part of matrix 1 is provided with through hole 4, and the periphery of the through hole of matrix 1 is fixed with reinforcing ring 2 (or claim to reinforce ring set, periphery is surrounded by reinforces ring set); The front of matrix 1 is provided with the grinding working lining 3 of ring-type, and reinforcing ring 2 is positioned at the inboard (as shown in Figure 1) of grinding working lining 3; The material of matrix 1 includes glass fibre or polyester-cotton blend (perhaps including glass fibre and polyester-cotton blend).

The material of described reinforcing ring 2 is metal (or other material).

The reverse side of described matrix 1 (or claiming the back side) is stained with the paper 5 (20g/m of one deck ring-type ²-200g/m ²), the middle part of paper 5 is a through hole.

The preparation of matrix 1 comprises any one among the following method:

1), the preparation of matrix 1: by horizontal vertical interweaving of glass fibre being made into fiberglass gridding cloth or plain, then between fiberglass gridding cloth or plain and fiberglass gridding cloth or the plain by resin or the bonding pressing of glue (multilayer pressing) together.

2), the preparation of matrix 1: by glass fibre and cotton fiber or wash and horizontal vertical interweaving of fiber be made into blended fiberglass cloth, then between blended fiberglass cloth and the blended fiberglass cloth by resin or the bonding pressing of glue (multilayer pressing) together.

3), the preparation of matrix 1: by horizontal vertical interweaving of glass fibre being made into glass fabric, glass fabric and cotton or wash between the cloth together then by resin or the bonding pressing of glue (multilayer pressing, multilayer woven glass fabric, multilayer cotton or wash cloth).

Described through hole is the through hole of different size.

The preparation of described grinding working lining 3 comprises any one among the following method:

1), elder generation sprays one deck glue (resin, glue) on matrix 1, is planting abrasive material (sand) on the glue then.

2), elder generation sprays ground floor glue on matrix 1, is planting abrasive material (sand) on the ground floor glue then, sprays second layer glue again on abrasive material.

3), elder generation sprays ground floor glue on matrix 1, is planting ground floor abrasive material (sand) on the ground floor glue then, sprays second layer glue again on the ground floor abrasive material, is planting second layer abrasive material (sand) on the second layer glue then.

4), on matrix 1, spray ground floor glue earlier, planting ground floor abrasive material (sand) on the ground floor glue then, spraying second layer glue on the ground floor abrasive material is being planted second layer abrasive material (sand) then on the second layer glue again, again the 3rd layer of glue of spraying on second layer abrasive material.

Effect contrast experiment: contrast piece (existing Grinding sand disc) and Grinding sand disc of the present utility model adopt (the same size) of same specification, the intensity 4500N of contrast piece, and intensity 8500N of the present utility model illustrates intensity height of the present utility model; The time in service life of contrast piece is 20 minutes, time in service life of the present utility model is 30 minutes, the utility model long service life is described, contrast piece soaks in water after 1 hour and is out of shape layering, the utility model soaks 96 hours indeformable, knockouts, not stratified not in water, illustrate that the water-fast weather resistance of the utility model is good; The contrast piece cost is 1.2 yuan one, and 1.0 yuan one of the utility model illustrates that the utility model cost is low; Contrast piece when the high speed rotary test, fragmentation when rotating speed reaches 21000 commentaries on classics/min, the utility model continuous operation under rotating speed 21000 commentaries on classics/min all stood intact in 30 minutes, illustrated that the utility model security is higher.
