FIELD: metallurgy.SUBSTANCE: male die houses the distributor with feed tube and tubes for compressed air discharge through die bores to under long semi-product central part. At the end of semi-product drawing and the start of male and female dies splitting compressed air is forced from the male die bores to facilitate detachment of the semi-product central sections from the male die surface.EFFECT: reliable detachment of semi-product from the male die, higher accuracy and quality, ruled out folds and fractures.2 cl, 2 dwg |
