Description
Изобретение относитс к области обработки металлов давлением и может быть использовано при листовой штамповке дл получени высоких бортов вокруг отверстий в плоских или жространственных заготовках.The invention relates to the field of metal forming and can be used in sheet punching to produce high beads around holes in flat or semi-dimensional blanks.
Известен способ отбортовки отверсти в листовой заготовке, при котором заготовку прижимают и опускающимс пуансоном осуществл ют пластическое деформирование 1.A known method of flanging a hole in a sheet billet, in which the billet is pressed and the plunging 1 is carried out by the lowering punch.
Недостатком этого способа вл етс то, что он не позвол ет за одну операцию получить относительную высоту борта больше предельной , определ емой технологическими возможност ми отбортовки.The disadvantage of this method is that it does not allow for a single operation to obtain the relative height of the bead more than the limit, determined by the technological possibilities of flanging.
Цель изобретени - увеличение высоты борта.The purpose of the invention is to increase the height of the bead.
Дл этого .по предлагаемому способу в начальный момент п-роцесоа край отверсти прижимают, затем осуществл етс формовка кольцевого углублени , после чего производитс окончательное деформировавдие без прижима.For this, according to the proposed method, at the initial moment of the p-process, the edge of the aperture is pressed, then an annular recess is formed, after which the final deformation is carried out without a clamp.
На фиг. 1 дана схема начальной стадии процесса; на фиг. 2 - процесс отбортовки в момент, когда Закончена предварительна формовка кольцевого углублени ; на фиг. 3- заключительна стади процесса отбортовки.FIG. 1 is a diagram of the initial stage of the process; in fig. 2 - flanging process at the moment when the pre-molding of the annular recess is completed; in fig. 3 - the final stage of the flanging process.
Заготовку / укладывают на матрицу 2, |црижимают ее прижимом 3, а Щ)ай отверсти прижимают кольцом 4. Дл дифференцированного нагрева заготовки используют электронагреватели 5.The workpiece / is laid on the matrix 2, it is pressed by the clamp 3, and S) and the hole is pressed by the ring 4. Electric heaters 5 are used to differentiate the heating of the blank.
Пуансон 6, опуска сь, производит формовку кольцевого углублени без изм-енени размеров отверсти . Предельную глубину/ формовки устанавливают в зависимости от геометрических параметров и мехаиических свойств штампуемого материала. 3/атем кра отверсти освобождают и продолжают отбортовку формоизмененной заготовки до получени борта 7.Punch 6, being lowered, forms a ring-shaped recess without measuring the size of the hole. The maximum depth / molding set depending on the geometric parameters and mechanical properties of the material being stamped. 3 / then the edge of the hole releases and continues the flanging of the modified billet until the bead 7 is obtained.
