Bi-dimensional pipe interface angle cutting control device

Abstract

The invention relates to two-dimensional manifold assembly interface angle incising control device. The main technological features lie in that a angle sensor and a control box is mounted on a treading electric machine, a control circuit mounted in the control box is controlled by monolithic computer, the monolithic computer computes the axial translation of stepping motor through manifold assembly diameter parameter, angle parameter and correlation parameter input by control box panel, input information transferred by angle sensor to drive the stepping motor to designated axial translation, a tread wheel and guiding wheel is mounted on lower part of tread motor, a rack bar is fixed on the tread trolley on which a tread motor is fixed, a rack bar tread mechanism is mounted on the rack bar, a stepping motor and cutting gun are mounted on the rack tread mechanism. The device incorporating the invention with simple and reasonable structure is suitable for manifold assembly with large or small ports and is a upgrade product of existing manifold assembly interface angle cut-off machine.

Description

[0001] Field [0002] The invention belongs to the field of steel pipe welding and cutting, in particular to a two-dimensional pipe interface angle cutting control device. Background technique [0003] With the needs of the development of the national economy, whether it is an above-ground pipeline or an underground pipeline, the construction mileage is developing rapidly, and the pipeline construction task is becoming more and more arduous. The entire pipeline is butted one by one according to surveying and mapping. However, due to surveying and mapping errors, deformation of the pipeline itself or other reasons, it often occurs that the angle of the pipeline interface deviates greatly during the butt joint, even far exceeding the national standard. Specified standard range (≤3°). In view of this situation, workers have to measure the angle and grind the interface by themselves to realize the docking. Because this kind of docking is completely realized manually, the work ef...

AI Technical Summary

Problems solved by technology

Because this kind of docking is completely done manually, the work efficiency is very low, labor-intensive and time-consuming, and the quality of the docking is relatively poor, which also lays hidden dangers for future pipeline leakage and heavy maintenance.

Existing similar technical devices are generally used for plane cutting of pipe joints, but cannot achieve angle cutting of pipe joints
