Description

Изобретение относитс  к области обработки листовых материалов давлением. Известен способ выт жки полых изделий из листовой заготовки, при котором в процессе деформировани  осуществл ют подачу смазки на поверхность заготовки. При этом пе происходит разделени  поверхности заготовки и матрицы слоем смазки, что приводит к ухудшению условий выт жки и снижению стойкости инструмента. С целью улучшени  условий выт жки в предложенном способе смазку подвод т под фланец заготовки от его периферии к центру непрерывно на прот жении всего процесса выт жки. Способ осуществл ют следующим образом. В процессе выт жки одновременно с началом деформации заготовки 1 (см. чертеж) через дренажный канал 2 и кольцевую канавку 3, расположенную на зеркале матрицы 4 у внещней границы выт жной кромки, подают смазку. Смазка, заполнив кольцевую канавку, смазывает поверхность заготовки, наход щуюс  над кольцевой канавкой, и увлекаетс  с заготовкой к выт жной кромке матрицы 4 и далее на калибрующий по сок. Подвод смазки к выт жной кромке матрицы прекращают только после окончани  процесса выт жки. Фор iM у л а Изобретени  Способ выт жки полых изделий из листовой заготовки, при котором в процессе деформировани  осуществл ют подачу смазки на поверхность заготовки, отличающийс  тем, что, с целью улучшени  условий выт жки , смазку подвод т под фланец заготовки от его периферии к центру непрерывно на прот жении всего процесса выт жки.This invention relates to the field of pressure sheet processing. There is a known method of drawing hollow articles from a sheet blank, in which, during the deformation process, lubricant is applied to the surface of the blank. In this case, there is no separation of the surface of the workpiece and the matrix with a layer of lubricant, which leads to a deterioration of the drawing conditions and a decrease in tool life. In order to improve the drawing conditions in the proposed method, the lubricant is fed under the flange of the workpiece from its periphery to the center continuously throughout the entire drawing process. The method is carried out as follows. During the stretching process, simultaneously with the onset of deformation of the workpiece 1 (see drawing), through the drainage channel 2 and the annular groove 3 located on the mirror of the matrix 4 at the outer edge of the exhaust edge, lubricant is applied. The lubricant, filling the annular groove, lubricates the surface of the workpiece, which is above the annular groove, and is carried along with the blank to the exhaust edge of the die 4 and then to the calibrating juice. The supply of lubricant to the exhaust edge of the die is stopped only after the end of the drawing process. FORM iMULA OF THE INVENTION A method for stretching hollow articles from a sheet billet, wherein during the deforming process lubricant is applied to the surface of the billet, characterized in that, in order to improve the conditions of the extrusion, lubricant is supplied under center continuously throughout the exhaust process.
