Large-diameter resin cutting blade and hardening method

Abstract

The invention belongs to the technical field of resin cutting discs, and particularly relates to a large-diameter resin cutting disc and a hardening method, the large-diameter resin cutting disc comprises a fixed metal sheet, and a step groove is fixedly formed in the surface of the fixed metal sheet. According to the large-diameter resin cutting blade and the hardening method, the cutting base ring fixedly sleeves the surface of the fixed metal sheet, and the reinforcing connecting layer is fixedly connected to the surface of the cutting base ring, so that when the large-diameter resin cutting blade is used, the diameter of the whole cutting blade is increased through the fixed metal sheet, and meanwhile, the overall strength and toughness of the cutting blade are improved; the reinforcing fiber nets and the reinforcing connecting layers are matched with the connecting clamping grooves and the connecting blocks, so that the connecting strength of the cutting parts and the fixed metal sheets is improved, meanwhile, the reinforcing fiber nets and the reinforcing connecting layers have the effect of improving the durability, the connecting strength and the toughness of the cutting blade, and therefore the problem that an existing resin cutting blade is poor in durability is solved. In order to solve the problem that the use range of resin cutting blades is limited due to the fact that most resin cutting blades are small in diameter when the resin cutting blades are broken and broken during use.

Description

technical field [0001] The invention relates to the technical field of resin cutting sheets, in particular to a large-diameter resin cutting sheet and a hardening method. Background technique [0002] Resin cutting discs use resin as the binder, glass fiber mesh as the backbone, combined with a variety of materials, especially for difficult-to-cut materials such as alloy steel and stainless steel. Two cutting methods, dry and wet, make the cutting accuracy more stable. At the same time, the choice of material and hardness of the cutting disc can greatly improve the cutting efficiency and save production costs. [0003] At present, during the use of resin cutting sheets, most of them have low durability and toughness, and are prone to breakage and breakage. Therefore, in order to reduce the fracture and breakage of resin cutting sheets during use, the existing resin cutting sheets Most of the diameters are small, although the fracture and breakage of the resin cutting discs ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the process of using resin cutting chips, most of them have low durability and toughness, and are prone to breakage and chipping. Therefore, in order to reduce resin cutting The chip breaks and breaks during use. Most of the existing resin cutting chips have a small diameter. Although it reduces the breaking and breaking of the resin cutting chip during use, it also limits the scope of use of the resin cutting chip, so There is a need for a large-diameter resin cutting sheet and its hardening method
