Abstract
Изобретение относитс к обработке металлов давлением, в частности к изготовлению вогнутого днища баллона. Цель изобретени - повышение производительности путем сокращени технологического цикла при изготовлении вогнутого днища и повышени его качества. Осуществл ют закатку предварительно нагретого конца вращающейс вокруг своей оси трубы путем поворота формовател (Ф) на требуемый угол в плоскости, перпендикул рной оси вращени трубы. Процесс формообразовани ведут с посто нной скоростью за один поворот Ф с одновременным подпором металла боковой поверхности баллона в зоне дна. Ф выполнен в виде сектора с углом при вершине 90° и содержит две рабочие поверхности дл формообразовани , состо щие из участка дл закатки днища, участка 3 дл раскатки плоского днища в вогнутое, участка 4 дл подпора металла боковой поверхности баллона в зоне дна, участка 5 дл калибровки радиусной части днища. При повороте Ф на угол, наход щийс в пределах 0 - 60°, производ т закатку плоского днища. По мере поворота на угол, наход щийс в пределах 60 - 90°, плоское днище раскатывают в вогнутое. 2 с.и 1 з.п. ф-лы, 7 ил.The invention relates to the processing of metals by pressure, in particular to the manufacture of a concave cylinder bottom. The purpose of the invention is to increase productivity by reducing the technological cycle in the manufacture of a concave bottom and improve its quality. The preheated end of the tube rotating around its axis is rolled by turning the former (F) to the required angle in a plane perpendicular to the axis of rotation of the tube. The process of forming is carried out at a constant speed in one turn F with simultaneous support of the metal of the side surface of the balloon in the bottom zone. Ф is made in the form of a sector with an apex angle of 90 ° and contains two working surfaces for shaping, consisting of a section for seaming the bottom, section 3 for rolling the flat bottom into concave, section 4 for supporting the metal of the side surface of the cylinder in the bottom zone for calibrating the radius of the bottom. When F is rotated through an angle between 0 and 60 °, the flat bottom rolls in. As you turn through an angle between 60 and 90 °, the flat bottom is rolled into a concave. 2 s. And 1 s. P. f-ly, 7 ill.
