Abstract
Использование: при обработке металлов давлением, преимущественно дл пробивки отверстий в стенах полых изделий с дном и отверстием в нем. Сущность изобретени : штамп с пуансоном, оправкой-матрицей и узлом ее поворота снабжен механизмом продольного перемещени из« i дели относительно оправки-матрицы. Механизм выполнен в виде направл ющих 37 с криволинейным и пр молинейным участками , толкател 38 и съемника 3. При подъеме верхней плиты 11 направл ющие 37 воздействуют криволинейным участком на ось 39 и через нее передают усили на съемник 3 и смещают заготовку 9 с оправки-матрицы 4 и фиксирующих пальцев 8. Полученный при пробивке отверсти заусенец при перемещении заготовки 9 вдоль оправки-матрицы 4 снимает режуща кромка оправки-матрицы 4. Заготовку 9 вместе с оправкой-матрицей 4 поворачивают направл ющие 13 с пр молинейным и криволинейным участками через храповое колесо 22 и стержень 5. Криволинейный участок направл ющих 13 расположен ниже криволинейных участков направл ющих 37. 9 ил. // /Usage: in the processing of metals by pressure, mainly for punching holes in the walls of hollow products with a bottom and a hole in it. SUMMARY OF THE INVENTION: a stamp with a punch, a mandrel matrix and a rotation assembly thereof is provided with a longitudinal movement mechanism from "i delhi relative to the matrix mandrel. The mechanism is made in the form of guides 37 with curvilinear and rectilinear sections, a pusher 38 and a puller 3. When lifting the upper plate 11, the guides 37 act on the axis 39 in a curved section and force is transmitted through it to the puller 3 and the workpiece 9 is shifted from the mandrel matrix 4 and fixing fingers 8. The burr obtained when punching the hole when moving the workpiece 9 along the mandrel matrix 4 removes the cutting edge of the mandrel matrix 4. The workpiece 9 together with the mandrel matrix 4 rotate the guides 13 with a straight and curvilinear m sections through the ratchet wheel 22 and the rod portion 5. The curved guide 13 located below the curved sections of the guide 37. 9 yl. // /
