V-shaped free bending intelligent control technology for sheet metal
Based on the research of plate deepening intelligent control technology, real-time identification and optimal process of material performance parameters are realized by LM optimization algorithm based on plastic bending theory and neural network technology through real-time monitoring of bending force and bending stroke. The real-time prediction of the parameters achieved a network convergence error of 1‰. The LabVIEW virtual instrument technology was used to establish a V-shaped free bending intelligent control experiment system for plates. Through the real-time control of the optimal stroke of the V-shaped free bending of the plate, the real-time control of the bending rebound is realized. The maximum error of the bending intelligent control of the two plates (SPCC steel plate, ST13 steel plate and brass) is 2.88% and 2.11% respectively. .
