| Popis: | 100 This study developed a virtual CNC piper bender, and conducted computer simulation before the actual processing of pipes. As conventional manual experiential judgment and the molding by the trial and error method would cost labor and raw materials, thus increasing the manufacturing costs, the proposed system can solve this problem. When the elbow pipe of the textile drawing frame is directly molded by the CNC piper bender, it is smoother for the unblocked transmission of cotton slivers while saving the mold development cost. This study applied the Taguchi method for experimental design, and used the CAE finite-element analysis software Abaqus to analyze the bending behaviors. The stress-strain and molding results were discussed to obtain the optimal travel parameters. According to the optimal travel parameters, this study implemented the 3D pipe bending processing and used the stress-strain gauge to measure the processed elbow pipes. By comparing the simulation analysis and the experimental data errors 6.39%, the verification results were close, proving that 3D pipe bending molding with the optimal travel parameters can reduce times of bending trials and raw material costs. This study successfully designed and simulated 3D pipe bending molding for pipes of different sizes, and employed the numerical method of regression analysis to establish the prediction equation for the optimal travel parameters. |
