Method for controlling shape adjusting spiral welded pipe forming machine and forming machine

Abstract

The invention belongs to the technical field of spiral welding pipe production, and particularly relates to a method for controlling a shape adjusting spiral welded pipe forming machine and the forming machine. Digital modeling is carried out on a steel pipe of each specification, and a database covering all the specifications is constructed through all parameters; when the specifications need tobe converted, the steel pipe specifications and raw material specifications are selected on a computer, and all adjusting mechanisms automatically carry out adjustment; each measuring mechanism carries out measurement, and when the measured numerical value is consistent with a database theoretical value, the adjusting mechanisms stop. At this moment, the forming machine complete shape adjusting work, and the needed steel pipe can be directly produced. Thus, dependency on shape adjusting workers can be reduced, the influence of human factors on the product quality is avoided, and the labor intensity is reduced; and the shape adjusting time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of production control of spiral welded pipes, and in particular relates to a control method for a shape-adjusting spiral welded pipe forming machine and a forming machine. Background technique [0002] The spiral welded pipe forming machine is the key equipment in the spiral welded pipe production line. It is mainly used to roll the steel strip sent by the delivery machine into a steel pipe. Since the axis of the steel strip and the axis of the steel pipe have an angle (45º-80º), this angle is called forming Angle, so the steel pipe advances along the axis while rotating, so that steel pipes of unlimited length can be produced, and then cut into steel pipes one by one according to the required length. [0003] The spiral welded pipe forming machine mainly works by pad rollers and six sets of rollers. The angle of the welding pad roller can be rotated, and it should be adjusted to the same angle as the formi...

AI Technical Summary

Problems solved by technology

At present, the adjustment work of the spiral welded pipe forming machine when changing specifications is manual calculation, manual operation and manual measurement. Although some adjustments are driven by motors, manual calculation and measurement of displacement are required, and adjustments with a high technical level are required. Only the shapers can complete the adjustment work, which increases the labor intensity of the workers, and requires a long adjustment time, and requires a high-level adjustment worker to complete, and the scrap rate of the steel pipes that have just been produced is also low. relatively high
