A steel coil longitudinal slitting device integrated with blade deep processing

PendingCN122583629AAvoid the disadvantages of downtime to remove bladesImprove operational efficiency
This invention relates to the field of metal cutting technology and discloses a steel coil slitting device integrating blade deep processing. The device includes a feeding machine tool with stabilizing side plates fixed at both ends. A drive assembly is mounted on the feeding machine tool, comprising two support frames fixed to the stabilizing side plates at both ends of the machine tool. A first drive mechanism and a second drive mechanism are mounted on the support frames. The first drive mechanism includes a rotating rod rotatably connected between the two support frames. By integrating blade maintenance functions onto the slitting machine tool and directly utilizing the cutting kinetic energy of the CNC blade rotation to drive the grinding and dust removal mechanisms, constant-pressure fine grinding and surface cleaning of the CNC blade sides can be simultaneously completed while the metal cutting and slitting operation continues. This achieves true online blade deep processing, avoiding the drawbacks of traditional methods that require stopping the machine to disassemble the blades, and greatly improving the overall operating efficiency and productivity of the equipment.

A reconfigurable metasurface beamforming design method based on CGAN and Gumbel-Sinkhorn

PendingCN122315358Aavoid mismatchHigh precisionMean squareAlgorithm
This invention proposes a reconfigurable metasurface beamforming design method based on CGAN and Gumbel-Sinkhorn. This method constructs a conditional generative adversarial network (GAN) as the inverse design network. The generator takes the target beam pattern as a conditional input to generate the corresponding encoding matrix. The Gumbel-Sinkhorn operator is introduced to discretize this continuous matrix, transforming it into an approximately doubly random permutation matrix. The encoding is sorted and selected by multiplying this permutation matrix with a predefined structure vector (SV), outputting a discrete 0 / 1 metasurface encoding array. A noisy forward prediction network is trained to predict the beam pattern corresponding to a given encoding array. In the training of the inverse design network, the discretized encoding matrix output by the generator is input into the noisy-trained forward prediction network. The mean square error between the predicted beam pattern and the target beam pattern is calculated as the target loss term to optimize the network parameters and accurately learn the complex mapping relationship from the beam pattern to the encoding array.
