Claims (1)

Способ изготовления кольцевых поковок без штамповочных уклонов, включающий штамповку полой заготовки с наклонными стенками и последующую последовательную проколку отверстия, обрезку облоя, правку и калибровку, отличающийся тем, что правку производят путем приложения усилия прошивки отверстия к криволинейной перемычке, выполненной выше торца меньшего основания полой заготовки, а затем осуществляют свободную калибровку по внутренней поверхности путем приложения противодействующего усилия к облою, расположенному в непосредственной близости к торцу большего основания заготовки, после этого производится обрезка облоя, при этом удаление поковки с калибрующего пуансона осуществляется при обратном ходе ползуна тыльной стороной обрезной матрицы.A method of manufacturing annular forgings without stamping slopes, including stamping a hollow billet with inclined walls and subsequent sequential puncturing of the hole, trimming the flake, dressing and calibration, characterized in that the dressing is performed by applying the force of hole piercing to the curved jumper made above the end face of the smaller base of the hollow workpiece and then carry out free calibration on the inner surface by applying a counteracting force to the area located in the immediate lizosti to the end of the greater base of the preform, after flash trimming is performed, the removal of the forging punch with sizing is performed during the return stroke of the slider back side edged matrix.
