Description
Предлагаемый способ повышени срока службы поршневых колец и цилиндровых втулок позвол ет значительно повысить их износостойкость . Способ заключаетс в гор чем обжатии поршневых колец в штампе.The proposed method of increasing the service life of piston rings and cylinder sleeves makes it possible to significantly increase their wear resistance. The method consists in hot-pressing the piston rings in the die.
На чертеже показана схема обжати поршневого кольца / на прессе пуансоном 2 в матрице 3.The drawing shows the scheme of compression of the piston ring / press punch 2 in the matrix 3.
Литую заготовку кольца после первой обточки нагревают в печи до 900-950°, обжимают s штампе и охлаждают до 300-400°. Дл уменьшени времени обжати штамп охлаждают проточной водой. После обжати заготовку кольца подвергают отпуску при 600° и окончательно обрабатывают.After the first turning, the cast ring billet is heated in the furnace to 900–950 °, compressed with the die and cooled to 300–400 °. To reduce the compression time, the stamp is cooled with running water. After crimping, the billet of the ring is subjected to tempering at 600 ° and finally processed.
Предмет изобретени Subject invention
Способ повышени износостойкости поршневых чугунных колец, отличаюш ийс тем, что, с целью повышени износостойкости, заготовки колец перед окончательной механической обработкой подвергаютс нагреву до 900-950° и обжимаютс в матрице с охлаждением до 300-400°, после чего вынимаютс из матрицы и подвергаютс отпуску лри 600°.The method of increasing the wear resistance of piston cast iron rings, is distinguished by the fact that, in order to increase the wear resistance, the billet rings are heated to 900-950 ° before final machining and compressed in a matrix with cooling to 300-400 °, after which they are removed from the matrix and subjected 600 ° temp.
