AI Technical Summary

Problems solved by technology

Saw blades made of metal alloy are mainly used for cutting ordinary carbon steel materials. They have high rigidity and are not easy to deform during use, but the blunt saw teeth must be trimmed frequently. When they cannot be used after a certain size, the saw blade is scrapped and cut The section deformation is serious, the burr is large, limited by the physical properties of the material itself, such as hardness and strength, it cannot cut alloy steel at all
Resin abrasive saw blades have a wide range of cutting applications, and both the cutting speed and the quality of the cut section can meet the requirements of use, but the material utilization rate of this type of saw blade is low (only about 70%)
The cutting saw blades used in the steel rolling production line require high cutting speed, good rigidity, high consumption and high price, and the utilization rate of saw blades has a great influence on the production cost

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] A composite cutting saw blade as shown in Figures 1 and 2, comprising a circular metal alloy substrate 1, the outer edge of the substrate is provided with tooth grooves 12 and through holes 11, and the saw blade also includes a circular saw body with resin abrasives 2. The circular saw body 2 is composed of resin abrasives 22, embedded with a reinforcing fiber mesh 21, and the fiber mesh 21 is fixedly connected to the outer edge of the base 1 through the through hole 11; wherein the tooth groove 12 on the base 1 and the through hole 11 In order to enhance the fixed connection strength between the matrix 1 and the saw body 2, the matrix 1 and the saw body 2 are tightly combined by a large-tonnage press through the pressing process, and are now cured at high temperature to increase the bonding strength and the rigidity of the saw body.

[0017] The composite cut...

Abstract

A combined saw disc is composed of a disc substrate made of alloy and a ring saw with abrasive resin material and fixed to the circumference of said disc substrate.

Description

technical field [0001] The invention relates to a compound cutting saw blade, in particular to a compound cutting saw blade for rapid cutting of alloy steel and ordinary steel, which is suitable for cutting alloy steel, forged alloy steel and ordinary steel on a rolling production line of a steel mill. Background technique [0002] At present, known saw blades are generally divided into three categories according to their uses: one is diamond saw blades mainly for cutting brittle materials such as stone, cement and tiles; the other is woodworking saw blades for cutting soft materials such as wood. ; The third is to cut metal and other plastic material-based cutting saw blades. In the third category, it is divided into metal alloy saw blades and resin abrasive saw blades according to the saw blade material. Saw blades made of metal alloy are mainly used for cutting ordinary carbon steel materials. They have high rigidity and are not easy to deform during use, but the blunt s...
