Abstract
Способ получения ступенчатых отверстий в деталях, заключающийся в получении исходного отверстия в заготовке, установке в него стержня длиной, меньшей толщины заготовки, фиксации заготовки в штампе, формировании упрочненного слоя путем осевого пластического сжатия обрабатываемого материала по периметру отверстия, образовании ступени посредством перемещения упрочненного слоя с последующим выполнением чистового отверстия, отличающийся тем, что, с целью повышения качества изделий за счет улучшения проработки структуры обрабатываемого материала на длине цилиндрического пояска, перед образованием ступени производят выдавливание кольцевого выступа с внешним диаметром, равным диаметру ступени, после образования чистового отверстия производят формирование упрочненного слоя с противоположной от ступени стороны путем установки в ступенчатое отверстие заготовки ступенчатого стержня длиной, меньшей толщины заготовки, и приложения посредством пуансона осевого усилия сжатия к торцевой поверхности кольцевого выступа, осуществляя пластическое сжатие обрабатываемого материала с заполнением свободного объема между торцами ступенчатого стержня и пуансона, после чего окончательно формируют чистовое отверстие в упрочненном слое.The method of obtaining stepped holes in the parts, which consists in obtaining the original hole in the workpiece, installing a rod with a length of smaller thickness of the workpiece, fixing the workpiece in the stamp, forming a hardened layer by axial plastic compression of the material being processed around the perimeter of the hole, forming a step by moving the hardened layer with the subsequent execution of the finishing hole, characterized in that, in order to improve the quality of products by improving the structure of the processed material on the length of the cylindrical belt, before forming a step, an annular protrusion is extruded with an outer diameter equal to the step diameter; after a finishing hole is formed, a hardened layer is formed from the side opposite to the step by installing a step length smaller than the workpiece thickness into the stepped hole of the workpiece and applying by means of a punch axial compression force to the end surface of the annular protrusion, carrying out plastic compression of the machined mat A series with the filling of free volume between the ends of the stepped rod and punch, after which the finishing hole in the reinforced layer is finally formed.
