A control method for automatically compensating a bending angle processed by a numerical control flanging machine

Abstract

The present application relates to the technical field of numerical control folding machine, and particularly relates to a control method for automatically compensating bending angle of numerical control folding machine processing. The method comprises the following steps: obtaining bending parameters by analyzing processing program; detecting plate strength through pre-bending action; calculating angle compensation value in real time based on bending parameters and plate strength through preset compensation algorithm model; calculating actual required bending angle A according to forming angle A S and forming angle compensation value A comp , and calculating trajectory coordinates P(x, y) of folding die end point based on the actual required bending angle A and movement trajectory algorithm of folding die; adjusting folding die movement trajectory according to compensation value and executing bending. The present application effectively solves the problem of bending angle deviation caused by plate strength fluctuation by real-time sensing of material property change and compensation, significantly reduces the waste rate and material loss in trial production and batch processing, and improves processing precision, production efficiency and equipment intelligent level.
