Abstract (en)
[origin: US2004139781A1] Billett forging method involves heating and forging with two manipulator press in several passes by four-sided reduction in four-headed forging devices and transversal direction metal macro-shears. In temperature range, rough and final forging is carried out enclosing 40 to 100% of the cross-section perimeter of the billet. Forging system comprises forging press with top and bottom plates having locks arranging and fixing forging tools, a movable tool table positioning changeable forging tools, as two or more four-headed forging devices and one or two manipulators. Four-headed forging devices for rough and final forging are disposed on the table. Free space between the final forging device closed heads is 1.1-1.4 times less than the space between the rough forging heads. Working surface planes of rough forging device heads are parallel to the reference plane of the head, and two adjacent lateral planes arranged on two sides at a 135-170 ° angle.
