Abstract
This invention relates to a manufacturing method and a die for producing stampings without burr on its edge by using a continuous stamping die. In the first step of processing, the semi-stamping is obtained by using a stamping die to press against the blank sheet to plastically deform specific area on the blank sheet partially. The edge of semi-stamping retains partial thickness and is connected with the blank sheet. In addition, the edge of semi-stamping on the blank sheet, corresponding to the recess of the lower die surface, forms fillister in a stepped shape to receive scrap. In the second step of processing, a coining die is used to press the aforementioned semi-stamping in a reverse direction to break the edge completely and separate from the blank sheet to from a coined smooth surface on the edge of stamping.
