Description
Изобретение относитс к обработке метошлов давлением, а именно к техно логии изготовлени деталей со сквозным отверстием. Известен способ изготовлени дета лей со сквозным отверстием,включающий осадку заготовки и формирование от- . версти в две стадии, на первой из которых осуществл ют неполную прошив ку осажденной заготовки со стороны одного из ее торцов, а на второй, после кантовки заготовки на 180 , производ т окончательное формирование отверсти fl . Недостаток известного способа состоит в повышенном расходе металла, удсш емого при оформлении отверсти . Цель изобретени - повышение, экономии металла. Поставленна цель достигаетс тем что в способе изготовлени деталей со сквозным отверстием, включающем осадку заготовки и формирование отверстий в две стадии, на первой из которых осуществл ют неполную прошив ку осаженной заготовки со стороны од ного из ее торцов, а на второй, после кантовки заготовки на 180 производ т окончательное формирование отверсти , неполную прошивку осуществ ют остроконечным пуансоном с наметкой отверсти на противоположном торце заготовки, а окончательное формирование отверсти производ т раздачей , внедр тот же пуансон в ранее намеченное отверстие. На чертеже представлена схема технологического процесса по стади м. а - взаимное расположение заготовки и инструмента} б - внедрение пуансона на всю высоту заготовки) в - кантовка заготовки на 180°) г - окончательное оформление отверсти . Способ осуществл етс следующим образом. Исходную заготовку осаживают, размещают под остроконечным пуансоном и внедр ют указанный пуансон в заготовку со стороны одного из ее торВ ходе деформировани осуществл етс оформление отверсти калибровочной частью пуансона. Внедрение пуансона осуществл ют до выхода острого конца пуансона с противоположного торца заготовки. После этого пуансон извлекают из поковки .The invention relates to the processing of pressure heads, namely to the technology of manufacturing parts with a through hole. A known method of manufacturing parts with a through hole includes the draft of the workpiece and the formation of ot-. Versts in two stages, at the first of which they carry out incomplete stitching of the besieged workpiece from one of its ends, and at the second, after turning the workpiece through 180, the fl aperture is finally formed. The disadvantage of this method is the increased consumption of metal, udish shaemoy when you make the hole. The purpose of the invention is to increase metal saving. This goal is achieved by the fact that in the method of manufacturing parts with a through hole, including the draft of the workpiece and the formation of holes in two stages, the first of which is incompletely stitched the deposited workpiece from one of its ends, and the second 180 produce the final formation of the hole, incomplete flashing is carried out with a pointed punch with a basting hole at the opposite end of the workpiece, and the final formation of the hole is produced by distributing p the same punch in the previously marked hole. The drawing shows a flow diagram of the stages m. A - the mutual arrangement of the workpiece and the tool} b - introduction of the punch to the full height of the workpiece) c - turning the workpiece 180 °) d - final clearance of the hole. The method is carried out as follows. The initial billet is deposited, placed under a pointed punch, and the specified punch is inserted into the billet from one of its ends. In the course of deforming, the hole is formed by the calibration part of the punch. The punch is inserted before the sharp end of the punch exits from the opposite end of the preform. After that, the punch is removed from the forging.
