Problems solved by technology

[0005] In the related art, in the process of trimming the edge trimming tool used, the cutting depth is often too small, or the cutting length is too long, or the cutting length is too short, etc., and the cutting is repeated, and even the inner part is repositioned. In the case of the liner, it can be seen that this kind of trimming tool will reduce the efficiency of pipe processing when trimming

Abstract

The invention relates to a trimming tool, and belongs to the technical field of pipeline processing. The trimming tool comprises a base, a shell, a first motor, a controller, a cutter, a depth detection part, a length detection part and a driving and reversing screw. The shell is installed on the base, the length detection part and the cutter are installed at the first end of the shell, the distance between the length detection part and the cutter is a first preset numerical value, and the depth detection part is installed at the second end of the shell; and the driving and reversing screw isinstalled in the shell, the first end of the driving and reversing screw is connected with the cutter, and the second end of the driving and reversing screw is connected with an output shaft of the first motor. When the controller receives an electric signal sent by the length detection part, the first motor is controlled to rotate according to the first direction, and the second end of the driving and reversing screw is controlled to move to the second position; and when the controller receives an electric signal sent by the depth detection part, the first motor is controlled to rotate according to the second direction, and the second end of the driving and reversing screw is controlled to move to the first position. The trimming tool can improve the pipeline processing efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of pipeline processing, in particular to an edge trimming tool. Background technique [0002] The inner wall of the pipeline used in oil and gas exploitation and oil and gas transportation is usually equipped with a liner to prevent oil and gas from corroding the pipeline. The liner is a corrosion-resistant tubular structure, such as a plastic pipe. [0003] The process of pipeline processing includes installing the liner in the pipe string. The installation process of the liner can be as follows: firstly, the technician will reduce the diameter of the liner according to the diameter of the pipeline, so that the diameter of the liner is smaller than the diameter of the pipeline. Diameter, so that the liner can be placed in the pipeline; then, use the edge trimming tool to trim the liner protruding from the pipeline. In the trimming process, the cutting depth needs to be determined according to the t...
