Abstract：

For the deep drawing of cylinder parts, the influence of die surface texture on stamping formability was studied, and the experimental results were compared. On this basis, the finite element model of texture on the deep drawing surface of cylinder parts was established by finite element software ABAQUS, the influence of basic structural parameters such as shape, size and distribution of texture on the deep drawing formability of cylinder parts were studied, and the influence laws of texture on sheet strain and thinning rate were explored. The results show that the design texture of the die surface has a certain influence on the formability. Compared with the die surface without texture design, designing triangular texture at the fillet of female die has the best effect, which can significantly reduce the maximum thinning rate of the deep drawing for cylinder parts and improve the stamping formability of sheet.
