METHOD OF FINE-CUTTING WORK PIECES, AND FINE-CUTTING TOOL FOR CARRYING OUT THE METHOD |
摘要 |
<p>Fine die stamping of workpieces from sheet metal is effected by clamping the workpiece between a die plate and guide plate, supporting the portion of the material to form the article by an ejector which is displaced along with the punch, and driving the supported portion of the material into a hole in the die plate having flanks tapered away from the guide plate and punch so that swaging occurs on the separated portion with or upon its separation from the balance of the workpiece material.</p> |
