Abstract
The invention discloses a floating male die forming device, which comprises a lower die holder and an upper die holder, the working faces of which are arranged opposite and matched; an ejector is arranged on the lower die holder; a part positioning device is arranged on the upper end face of the ejector; an ejector jacking device is arranged between the ejector and the lower die holder; the ejector is also provided with a male die through hole; a male die passing through the ejector is arranged in the male die through hole; and a support plate is arranged between the male die and the lower die holder. During working, the ejector is jacked, a part is fixed on the ejector, and then the ejector is higher than the male die; when an upper die presses a lower die, part flanging and web formation are completed; the upper die continuously moves downwards, the ejector moves downwards, the upper surface of the male die is gradually higher than the upper surface of the ejector, and reinforcing rib formation starts; and when the upper die moves downwards to a lower dead point, the part reinforcing rib formation is completed. The problem of instable positioning is solved by positioning and forming in turn; and the part flanging, the web formation and the reinforcing rib formation are performed separately, so the quality of the formed product is ensured.
