APPARATUS AND METHOD OF SHEARING FOR QUALITY IMPROVEMENT FOR STEEL PLATE SHEARING EDGE |
| 摘要 |
The present disclosure provides a shearing method for improving the quality of a steel plate shearing edge, and a shearing apparatus to improve the quality of the steel plate shearing edge. The apparatus includes: a die; a stripper for fixing a steel plate positioned on the top of the die; a trim punch for shearing the steel plate fixed between the die and the stripper, and a finishing die for reducing an area ratio of a fracture surface of a shearing edge formed by shearing the steel plate and removing a burr. By using the apparatus, components can be prevented from being damaged and a life-span can be increased through removing a burr generated at the shearing edge of the steel plate and reducing a fracture surface ratio. |
