Description
проверка npennaraeNioro способа проводитс при обработке внутренней поверхности цилиндра гвдравлического гасител колебаний, имеющего следующие параметры:The npennaraeNioro check of the method is carried out by treating the inner surface of the cylinder of the hydraulic vibration damper having the following parameters:
Марка материаласт 45;Grade materials 45;
Длина цилиндра (глубинаCylinder length (depth
отверсти )214 мм;holes) 214 mm;
Толщина стенки пшшпдра5 мм;Wall thickness pshshpdra5 mm;
Диаметр отверсти 68 А.The diameter of the hole 68 A.
После растачивани отверсти до диаметра 67,92 мм производитс упрочн юще-стабилизирующее раскатьшание отверсти с иат гом, равным 0,15-0,20, затем хонингование отверсти до диаметра 68 с последующим выглаживающе-чистовым раскатьтанием с нат гом , равным 0,1-0,14 мм, что составл ет 0,6-0,7 от величины нат га, прин того дл предварителыюго упро«ш юще-стабилизирующего раскатывани .After boring the hole to a diameter of 67.92 mm, a reinforcing-stabilizing rolling of the hole is made with an atomic of 0.15-0.20, then honing the hole to a diameter of 68, followed by smoothing-finishing unraveling with a tension of 0.1- 0.14 mm, which is 0.6-0.7 of the amount of tension that has been adopted for the preliminary, easy-to-stabilize rolling.
Проведенные экспериментальные работы показали , что предлагаемый способ позвол ет стабильно получать отверсти в тонкостенных детал х по второму классу точности, с чистотой поверхности - 11 класса и степенью повыщени поверхностной твердости от 45% до 60%Experimental work has shown that the proposed method permits stably producing holes in thin-walled parts according to the second accuracy class, with a surface finish of 11 class and a degree of surface hardness increase from 45% to 60%

детал х методом раскатывани создает возможность получени )а1рочненной износостойкой поверхности при одновременном получении высокого качества этих отверстий. 5Details using the rolling method make it possible to obtain an augmented wear-resistant surface while at the same time obtaining high quality of these holes. five
Форму л,а изобретени Form l, and the invention
Способ обработки отверстий поверхностным 10 пластическим деформированием, включающий предварительное раскатывание, с нат гом, обеспечивающим упрочнение поверхностного сло , промежуточную механическую обработку и повторное раскатывание, отличающий15 с тем, что, с целью возможности обработки тонкостенных деталей и получени их высокой точности, повторное раскатывание производитс с иат гом, равным 0,6-0,7 от челичины нат га , прин того при предварительном раска20 тывании,The method of processing the holes by surface 10 plastic deformation, including pre-rolling, with a tension that provides hardening of the surface layer, intermediate mechanical treatment and re-rolling, which differs 15 so that, in order to process thin-walled parts and obtain their high accuracy, re-rolling iatom, equal to 0,6-0,7 from chelichina nat hectares, accepted at preliminary repentance,
