Steel pipe cutting machine

Abstract

The invention relates to a steel pipe cutting machine. The steel pipe cutting machine comprises a rack, a first motor, a rotating drum, friction assemblies, an installing drum rotatably arranged in the rotating drum in a matched mode, sleeves, a rotating pipe, a first air bag arranged in the rotating pipe, an air supplying mechanism used for supplying air to the first air bag, a second motor slidably installed in the installing drum and a cutting disc which is in transmission connection with an output shaft of the second motor; an output shaft of the first motor, the rotating drum and the installing drum are coaxially arranged; the sleeves and the installing drum are arranged in parallel; the first air bag is shaped like a cylinder and provided with a channel used for allowing a steel pipeto penetrate; and sleeves are connected to the rack. According to the steel pipe cutting machine, rotating fit between the rotating pipe and the sleeves is skillfully utilized, rotation of the friction assemblies (particularly, friction layers) on the steel pipe is combined, therefore, the steel pipe needing to be cut can rotate, the steel pipe is cut in the rotating process, uniform cutting canbe conducted, the cutting quality is improved, and meanwhile the cutting disc can be better protected.

Description

technical field [0001] The invention relates to a steel pipe cutting machine. Background technique [0002] Existing steel pipe cutting machines are divided into planetary cutting machines, hydraulic cutting machines, external card cutting machines, CNC hydraulic cutting machines, electric cutting machines, pneumatic cutting machines and other models, but the existing cutting machines generally need to be refurbished It is not convenient to use the clamp alone to tighten the steel pipe, and when cutting the steel pipe, only one surface is cut, which is easy to increase the wear of the cutting blade. When the steel pipe needs to be rotated, the clamp needs to be adjusted. Trouble, it is inconvenient to cut uniformly while rotating the steel pipe, and when the existing steel pipe is cut, generally only a single steel pipe is cut, it is inconvenient to cut multiple steel pipes at the same time, which affects the cutting efficiency, and the existing When clamping steel pipes, d...

[0002] Existing steel pipe cutting machines are divided into planetary cutting machines, hydraulic cutting machines, external card cutting machines, CNC hydraulic cutting machines, electric cutting machines, pneumatic cutting machines and other models, but the existing cutting machines generally need to be refurbished It is not convenient to use the clamp alone to tighten the steel pipe, and when cutting the steel pipe, only one surface is cut, which is easy to increase the wear of the cutting blade. When the steel pipe needs to be rotated, the clamp needs to be adjusted. Trouble, it is inconvenient to cut uniformly while rotating the steel pipe, and when the existing steel pipe is cut, generally only a single steel pipe is cut, it is inconvenient to cut multiple steel pipes at the same time, which affects the cutting efficiency, and the existing When clamping steel pipes, different clamps are required to tighten steel pipes of different thicknesses, which is more troublesome. After cutting the steel pipes, it is also inconvenient to protect the cut steel pipes, and it is easy to make the steel pipes fall directly to the ground. On, it is not easy to protect the steel pipe
