Abstract

Способ штамповки сильфонов из трубных заготовок эластичной средой в жестких матрицах, включающий последовательное формообразование гофров раздачей внутренним давлением эластичной среды при осевом перемещении свободного конца трубной заготовки, отличающийся тем, что материал трубной заготовки для формообразования гофров выбирают в соответствии с его относительным удлинением после разрыва δ, определяемым по зависимости:δ(a,b)=A(b)a+B(b)a+С(b),где A(b)=29,23b-18,59b+1,43;B(b)=-31,98b+28,62b-3,24;C(b)=6,97b-10,24b+1,82;R=d/2+r;R=D/2-r;r- радиус у основания и при вершине гофра;d - диаметр проходного сильфона,D - диаметр гофра.A method of stamping bellows from tube stocks with an elastic medium in rigid matrices, comprising sequentially shaping the corrugations by distributing internal pressure of the elastic medium while axially moving the free end of the tube stock, characterized in that the tube blank material for forming the corrugations is selected in accordance with its elongation after rupture δ, determined by the dependence: δ (a, b) = A (b) a + B (b) a + C (b), where A (b) = 29.23b-18.59b + 1.43; B (b) = -31.98b + 28.62b-3.24; C (b) = 6.97b-10.24b + 1.82; R = d / 2 + r; R = D / 2-r; r- radius at the base and at the top of the corrugation; d - diameter p flow bellows, D - diameter of the corrugation.
