The cutting piece is generally formed by bonding a glass fiber net and an abrasive material through a bonding agent, and the cutting piece is found to be very brittle and not enough in strength in practical use, and meanwhile, stress generated in use cannot be eliminated, so that the phenomenon of breakage is easily caused, and the product is scrapped.

Open (notice) No. CN110340445A a cutting piece for high strength cutting machine, including cutting piece body, cutting piece body includes the substrate layer, and the substrate layer both sides all are provided with the high strength protective layer, and the high strength protective layer adopts the high temperature spraying mode to coat on the substrate layer. The invention has simple structure, long service life and high strength protection layer, is not easy to corrode and break, is not easy to corrode by air, prolongs the service life and reduces the production cost. Above-mentioned technical scheme increases the intensity of cutting disc through setting up the high strength protective layer, but, can only increase the intensity of cutting disc itself, can not eliminate the influence of the stress that produces when using to the cutting disc.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the intensity difference of cutting piece among the prior art, the unable elimination of stress that produces in the use influences the problem of cutting piece intensity. Increase the intensity of cutting piece self through setting up the high strength protective layer, set up the through-hole simultaneously and fill toughness resin in the fibre web layer inside and eliminate the stress that produces in the use, prevent that stress from causing the damage to the cutting piece.

In order to achieve the purpose, the utility model discloses a high strength cutting piece, including metal substrate and cutting lamellar body, cutting lamellar body fixed connection be in metal substrate's the outside, the cutting lamellar body includes metal mesh layer, fiber network layer, the abrasive material layer that bonds through the resin binder by supreme setting gradually down, the inside packing of fiber network layer has the toughness resin, the outside on abrasive material layer is provided with the high strength protective layer, set up one row of through-hole along its radial arrangement on the metal substrate, the through-hole next-door neighbour cuts the lamellar body setting.

Further, the utility model discloses an among the technical scheme, be provided with central shaft hole on the metal base member for connect the axis of rotation of cutting machine.

Further, in the technical solution disclosed in the present invention, the aperture of the through hole is smaller than the distance between the adjacent through holes.

Furthermore, in the technical solution disclosed in the present invention, the high-strength protective layer is a zinc coating.

Further, in the technical solution disclosed in the present invention, the thickness of the high-strength protective layer is 2-4 um.

Further, the utility model discloses an among the technical scheme, the high strength protective layer adopts the high temperature spraying mode to coat in the abrasive material layer outside.

Further, the utility model discloses an among the technical scheme, be provided with the chip groove between the cutting lamellar body.

The utility model discloses beneficial effect does: 1. the metal substrate is provided with through holes for radiating and dispersing the stress of the cutting sheet body; 2. the cutting sheet body is provided with the high-strength protective layer, so that the strength of the cutting sheet body is increased, and the cutting sheet body is not easy to bend and break; 3. the fiber net layer is filled with tough resin, so that stress generated when the cutting sheet body is used can be eliminated.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
