A dual-purpose saw blade for cutting and grinding

Abstract

The invention relates to a dual-purpose saw blade for cutting and grinding, which includes a saw blade body, a double-layer cutter head, tooth backs and a grinding wheel. A groove is provided, and the double-layer cutter head is welded in the groove; the grinding wheel includes an upper grinding wheel and a lower grinding wheel, both of which are ring-shaped, and the upper grinding wheel and the lower grinding wheel are respectively arranged on On both sides of the saw blade body, the saw blade body, the upper grinding wheel and the lower grinding wheel are all provided with through holes for bolts that are adapted to each other, and the upper grinding wheel and the lower grinding wheel are fixed on the saw blade body by bolts; the present invention It can finish cutting and grinding the cutting surface at the same time, which greatly improves the efficiency, and improves the flatness of the grinding surface, the verticality of the grinding surface and the profile. The impact on the saw blade teeth, the cutter head is not easy to drop.

Description

technical field [0001] The invention relates to the technical field of cutting equipment for steel and wood, in particular to a saw blade for cutting and grinding. Background technique [0002] Circular saw blades are widely used in metallurgy, machinery, stone processing and other industries. When cutting aluminum alloy, plastic steel, color steel plate, solid wood, particle board, MDF and other materials, due to the existence of cutting surface knife marks, chipping or burrs after cutting The problem is that the overlap of the cutting surface is low, and the cutting surface needs to be polished after cutting, so that the cutting equipment and the grinding equipment need to be equipped with a saw blade and a grinding wheel (generally, an angle forward grinder is used for grinding the surface), or a cutting and grinding machine is required. Use an angle-forward grinder for the surface, and replace the tools on the angle-forward grinder to perform alternate work, which increa...

Problems solved by technology

[0002] Circular saw blades are widely used in metallurgy, machinery, stone processing and other industries. When cutting materials such as aluminum alloy, plastic steel, color steel plate, solid wood, particle board, density board, etc. The problem is that the coincidence of the cutting surface is low, and the cutting surface needs to be polished after cutting. In this way, the cutting equipment and the grinding equipment need to be equipped with saw blades and grinding wheels respectively (generally, an angle forward grinder is used for grinding), or cutting grinding Use the angle forward grinder for the surface, change the tool on the angle forward grinder, and perform alternate work, which will increase the working time of the operator and reduce the work efficiency, and the flatness of the grinding surface, grinding surface and profile The verticality is not good
