Problems solved by technology

When the oil pipe and the pressure cutting oil pipe device are not concentric, problems such as knife jamming, knife breaking, and oil pipe incision are prone to occur during the cutting process with the existing cutting knife, which cannot meet the requirements of on-site use
However, the existing circular cutters are mainly used for cutting plastic pipes and thin-walled pipes with low hardness, and are not suitable for cutting oil pipes.

Embodiment Construction

[0019] see Figure 1 to Figure 4 , the present invention relates to a pipe cutting tool, in particular to an oil pipe cutting tool, the specific structure of which is:

[0020] Including the tool body, the tool body extends from the root 3 to the blade 1 through the blade face 2, and the center of the cutter body is provided with a mounting hole 4; the blade face 2 is a full circle and the thickness of the blade face 2 gradually increases from the blade 1 to the blade root 3 . The blade 1, the blade surface 2 and the blade root 3 can rotate around the installation hole 4, and the blade 5 actively rotates around the center of the oil pipe 6 to be cut O Rotate, move radially towards the oil pipe on one side, and squeeze the oil pipe to realize cutting. Since the cutter adopts extrusion cutting, no chips are generated. Since the contact surface between the cutter and the oil pipe increases with the increase of the depth of cut, it can prevent the cutter from jamming due to the ...

Abstract

The invention relates to an oil pipe cutter. The oil pipe cutter is characterized in that the oil pipe cutter comprises a cutter body, wherein the cuter body is formed by extending a cutter root (3) to a cutter blade (1) through a cutter face (2), an installation hole (4) is formed in the center of the cutter body, the cutter face (2) is a full circle, and the thickness of the cutter face (2) is gradually increased from the cutter blade (1) to the cutter root (3). The oil pipe cutter has the advantages of being capable of resisting clamping, preventing break, and resisting shock, incisions of oil pipes are neat, chips are absent during cutting processes, and use requirements for cutting oil pipes on site can be met.

Description

technical field [0001] The invention relates to an oil pipe cutter. Background technique [0002] Tubing cutters are used to cut tubing installations under pressure. During the cutting process, the oil pipe does not move, and the cutter rotates around the oil pipe. When the oil pipe is not concentric with the pressure cutting oil pipe device, problems such as knife jamming, knife breaking, and irregular oil pipe incision are likely to occur during the cutting process with the existing cutting knife, which cannot meet the requirements of on-site use. However, the existing circular cutters are mainly used for cutting plastic pipes and thin-walled pipes with lower hardness, and are not suitable for cutting oil pipes. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil pipe cutting tool to overcome the defects in the prior art. [0004] The technical solution solved by the present invention is: A tubing cutter,...
