AI Technical Summary

Technical Problem

Existing diamond saw blades have safety and efficiency problems when cutting reinforced concrete. Especially when used in harsh environments, the cutting head is prone to fall off, affecting the cutting quality and safety.

Method used

A laser-welded diamond saw blade is designed, using multiple diamond cutter heads to evenly arrange them on the outer circumference of the base body, forming a V-shaped groove and an arc-shaped groove. The outer end face of the cutter head is designed as a Great Wall tooth structure, and is connected to the base through double-sided laser welding technology to optimize the chemical composition of the cutter head and welding process parameters.

Benefits of technology

It improves the safety and stability of the saw blade, enhances the bending strength and heat resistance of the cutter head, ensures more durable and safe cutting under extreme conditions, and improves construction efficiency.

Abstract

The present invention discloses a laser-welded diamond saw blade for cutting reinforced concrete and a preparation process thereof, and belongs to the technical field of reinforced concrete cutting tools. The laser-welded diamond saw blade comprises a circular base and a diamond cutter head welded on the outer edge of the base, wherein: the diamond cutter heads are multiple and evenly arranged on the outer circumference of the base, and a V-shaped groove is formed between adjacent diamond cutter heads, and the V-shaped groove extends an arc groove I into the base; the outer end face of the diamond cutter head is designed as a Great Wall tooth structure. The cutter head raw materials are composed of copper, iron, tin, nickel, manganese, tungsten carbide powder, diamond, and liquid paraffin, and the cutter head and the base are laser welded into one. The present invention optimizes the cutter head formula and the cutter head shape so that the laser blade for cutting reinforced concrete can be quickly cut into position through the outer circular teeth. As the cutting depth increases, the subsequent diamond cutter heads gradually expand, and the continuous U-groove can meet the construction needs of various road conditions.
