Processing technology for whole spherical iron piston

Abstract

The invention discloses a processing technology for whole spherical iron piston, and the method comprises the following steps: step a, cutting a riser; step b, carrying out rough turning on a head, measuring the thickness and marking off; step c, carrying out rough turning on a spigot and an excircle, carrying out heavy boring on a pin hole and an end face, and carrying out rough turning on the excircle and a combustion chamber; step d, carrying out precipitation heat treatment; step e, carrying out finish turning on the spigot and milling a center hole; step f, carrying out semi-finish turning on the excircle, and carrying out semi-finish boring on the pin hole; step g, milling a table face; step h, drilling a deep hole; step i, turning a seat end face and turning a macropore; step j, drilling a hole; step k, carrying out finish boring on an internal space, drilling a straight hole and drilling a hinge screwed hole; step l, carrying out finish boring on the pin hole, milling an oil gallery, chamfering an vehicle shield ring groove and the pin hole, and tapping; step m, carrying out finish turning on appearance, carrying out finish turning on the ring groove and carrying out finish turning on the combustor chamber; step n, milling an avoided valve hole, opening the avoided valve hole, and drilling a hinge hoisting hole; step o, carrying out a hydrostatic test, laser quenching and fitter polishing, and spraying molybdenum disulfide. The processing technology for the whole spherical iron piston in the invention has the advantages of high process precision, rigorous process flow and superior processed product quality.
