Abstract

The invention discloses a square pipe cutting device which comprises a bottom supporting board. A supporting frame, an operation handle, a motor, a reduction gearbox connected with the motor and a grinding wheel saw web connected with the reduction gearbox are arranged on the bottom supporting board. The grinding wheel saw web comprises, by weight, 19 to 20 parts of white corundum, 18 to 19 parts of bauxite sintered alumina, 3 to 3.5 parts of polyvinyl chloride fibers, 1.9 to 2 parts of copper powder, 1.9 to 2 parts of tungsten carbide, 2 to 2.1 parts of potassium oxide, 2 to 2.5 parts of polytetrafluoroethylene powder, 2.5 to 3 parts of lignin fibers, 1 to 1.3 parts of calcium sulfide, 4.8 to 5 parts of cast stone, 5 to 5.8 parts of cubic silicon carbide, 1.9 to 2 parts of nitrile rubber, 3 to 4 parts of nano-boron fibers, 2 to 2.8 parts of epoxy resin and 3 to 3.5 parts of phenolic resin. In this way, the square pipe cutting device is simple and reasonable in structure, the strength of the grinding wheel saw web is high, and the cutting device is suitable for cutting square pipes.

Description

technical field [0001] The invention relates to the technical field of cutting supplies, in particular to a square pipe cutting device. Background technique [0002] Grinding wheel cutting machine is a commonly used cutting machine, which is mainly used to cut square tubes, round tubes, special-shaped tubes, etc. with small diameters. The grinding wheel cutting machine is light, flexible, simple and convenient to use, and is widely used in various occasions, especially in construction sites and interior decoration. [0003] The grinding wheel is the most critical component in the grinding wheel cutting machine, which is directly related to the performance and work efficiency of the grinding wheel cutting machine. When the existing grinding wheel cuts the square pipe, it is blunt and not sharp enough, and produces many burrs. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a square pipe cutting device, which ha...
