Abstract
Способ изготовления штамповок лопаток с двумя хвостовиками переменного сечения горячим выдавливанием, где нагретую заготовку подают в контейнер, производят выдавливание заготовки через канал составной матрицы, состоящую из левой и правой конических полуматриц, при этом формируют штамповку переменного сечения, расширяющуюся к оставшейся части заготовки в контейнере, отличающийся тем, что до выдавливания по средствам смыкания полуматриц до определенной величины и движения верх нижнего пуансона, электромеханически связанного с выталкивателем пресса, происходит предварительное формирование одного из хвостовиков лопатки.A method of manufacturing stampings of blades with two shanks of variable cross section by hot extrusion, where a heated billet is fed into a container, the billet is extruded through a channel of a composite matrix consisting of left and right conical half-matrices, while forming a stamping of variable cross section expanding to the remaining part of the workpiece in the container, characterized in that before extrusion by means of closing the half-matrices to a certain size and movement of the top of the lower punch, electromechanically connected to the push After being a press, a preliminary formation of one of the shanks of the blade occurs.
