Axial cutting machine for steel pipe

Abstract

The invention relates to an axial cutting machine for a steel pipe. The technical scheme is that a milling cutter (4) is arranged on an output shaft of a speed regulating motor (19) mounted on an upper plane of a platform; radial sliding blocks (9) which are installed at four corners of a lower plane of the platform (6) are sleeved on corresponding sliding rods (10) at the same side in a sliding manner; sliding rods (10) are respectively fixed at two sides of an axial sliding block (5); the axial sliding block (5) is sleeved on a guide rail (3) in the sliding manner; the axial sliding block (5) is driven to slid along the guide rail (3) through an axial feeding flywheel (2) by utilizing threads, so as to drive the milling cutter (4) to axially move along the steel pipe (1); the platform (6) is driven to slide along the sliding rods (10) through a radial feeding flywheel (7) by utilizing the threads, and therefore, the milling cutter (4) can move along the steel pipe (1) in the radial direction; and a cutting machine is fixed on the steel pipe (1) by adjusting a movable clamping block (14) through a clamping hand wheel (17). According to the axial cutting machine for the steel pipe, a mechanical cutting mode is adopted; the axial cutting machine for the steel pipe has a simple structure, and is suitable for being applied to axially cutting a steel pipe, a natural gas pipeline, a petroleum pipeline and the like which are provided with cables in a paving way; and the axial cutting machine has a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of steel pipe cutting machines. Specifically relates to a steel pipe axial cutting machine. Background technique [0002] With the development of society, steel pipe products are widely used in all walks of life, and there are more and more processing methods for steel pipes. There are a large number of steel pipe cutting equipment on the market, such as electric cutting machines and oxygen cutting devices, but these equipment are mainly aimed at the treatment of steel pipes before installation, and are mainly used for end face cutting of steel pipes, that is, radial cutting, so there are Certain limitations. [0003] At present, when repairing a pipeline with cables laid, it is often necessary to strip and cut part of the damaged pipeline, that is, to cut axially and radially. Due to the particularity and complexity of the construction site, special equipment is required to carry out the cutting. To ensu...

Problems solved by technology

In addition, because the cable itself cannot withstand high temperatures, in order to ensure safety, the cutting equipment needs to generate less heat during the cutting process. A large number of existing cold cutting processing equipment can only achieve radial cutting of steel pipes
