Abstract

In this study, numerical modeling and experimental tests of the sheet metal cutting process were carried out in order to determine the shape of the cutting knives for a roller shear, ensuring the minimization of burr on the cut edge. A rolling mill was used for the tests, enabling the replication of the cutting process in a roller shear (demonstrating the possibility of using cutting rollers). The cutting edges of the sheets were examined using light microscopy and then compared with the results of numerical simulations to determine the cutting quality. The tests were performed for multiphase Complex Phase (CP) grade steel. The initial thicknesses of sheets were equal to 1 and 2 mm. Based on the results of theoretical research, four shapes of cutting rollers were designed, of which two shapes were selected for experimental tests. The analysis of the test results shows that the lowest burr values were obtained for straight and beveled rollers. Analyzing the size of burr obtained in experimental tests, it can be concluded that for each of the two variants of the roller shape, a reduction in burr was achieved. Greater reductions in burr were achieved for shaped (cut) rolls.

摘要

在本研究中，为了确定滚剪机切割刀具的形状，进行了金属板切割过程的数值模拟和实验测试，以确保切割边缘毛刺最小化。使用轧机进行测试，能够在滚剪机中复制切割过程（证明了使用切割辊的可能性）。使用光学显微镜检查板材的切割边缘，然后与数值模拟结果进行比较，以确定切割质量。测试针对多相复合相（CP）级钢进行。板材的初始厚度分别为1毫米和2毫米。基于理论研究结果，设计了四种形状的切割辊，其中选择了两种形状进行实验测试。测试结果分析表明，直辊和斜辊的毛刺值最低。分析实验测试中获得的毛刺尺寸可以得出结论，对于两种辊形状变体中的每一种，都实现了毛刺的减少。成型（切割）辊的毛刺减少幅度更大。
