Abstract

The invention discloses a square tube cutting machine. The square tube cutting machine comprises a worktable. The worktable is provided with a drive device, a double-cross universal joint and a shearing device. The drive device is connected with the shearing device through the double-cross universal joint. The drive device comprises a supporting block and a motor located on the supporting block, and the supporting block is arranged on the worktable in a sliding mode. The shearing device comprises a shearing piece, a rotary shaft and a lifting component, the rotary shaft is located in the center of the shearing piece, and the lifting component is located at the upper end of the shearing piece and connected with the rotary shaft. The lifting component comprises a shell, an iron plate is arranged in the shell and matched with the inner wall of the shell, and two connection columns are arranged between the lower surface of the iron plate and the rotary shaft. The two connection columns are located on the two sides of the shearing piece respectively and connected with the iron plate and the rotary shaft. A spring is disposed between the upper surface of the iron plate and the upper wall of the shell. An electromagnetic block is arranged on the upper wall of the shell and connected with an electric control box through a circuit. Square tubes are prevented from being bent after being cut off, cost is reduced, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a square pipe cutting machine. Background technique [0002] Square pipe cutting machine is one of the essential equipment for square pipe processing. It is mainly used for cutting square pipes to fixed length in housing construction, bridges, tunnels, power stations, large water conservancy and other projects. Compared with other cutting equipment, the square tube cutting machine has the characteristics of light weight, less energy consumption, reliable operation and high efficiency. At present, most square pipe cutting machines rely on the shear force generated by the moving knife and the fixed knife to cut the square pipe, which often bends the cut end, which cannot meet the construction needs. And some thicker square tubes need a lot of shearing force to cut off, which requires a lot of driving force, increases the cost, and reduces the service life of the too...
