Pipe cutting device and control method thereof

Abstract

The invention relates to a pipe cutting device and a control method thereof. The device comprises a pipe conveying mechanism for conveying a pipe to a pipe cutting mechanism to perform pipe cutting operation and the pipe cutting mechanism for executing the pipe cutting operation, wherein the discharge part of the pipe conveying mechanism is engaged with the feeding part of the pipe cutting mechanism, and a receiving rack of the pipe conveying mechanism is positioned at a position for keeping the center of the pipe and the center of a pipe through hole of the pipe cutting mechanism coaxial. The method comprises the following steps of: initializing the parameters and the mechanisms; if the pipe is conveyed in place, starting conveying the pipe; when the pipe head reaches a pipe head detection switch, recording the current position of a pipe conveying servo motor as a pipe initial position; when the condition 1 is met, stopping conveying the pipe by the pipe conveying servo motor; calling a pipe cutting subprogram; if the pipe needs to be continuously cut after the pipe is cut, recording the current position of the pipe conveying servo motor as a cut pipe position, and continuously performing pipe conveying operation till the condition 2 is met; and calling the pipe cutting subprogram again to perform the pipe cutting operation. Fixed length cutting of the large-diameter pipe is realized in a milling mode, and reliability and high efficiency of the whole pipe cutting process are ensured.

Description

technical field [0001] The invention relates to an automatic pipe cutting device, in particular to a pipe cutting device and a control method thereof. Background technique [0002] Automatic pipe cutting machines are widely used in industrial production. Commonly used automatic pipe cutting machines correspond to pipe diameters below 50mm, and adopt a single saw blade for straight-line cutting. For larger pipe diameters, there are also automatic pipe cutting machines that use turning methods. The straight-line cutting method with a single saw blade is limited by the size of the saw blade and the stroke of the driving mechanism, so it is only suitable for small pipe diameters; while the turning method can cut larger pipe diameters, but the collection of long iron filings It is more difficult, which makes this cutting method less efficient and can only be operated by a single machine, which is not suitable for matching with automatic production lines. At present, the demand ...
