FIELD: process engineering.SUBSTANCE: invention relates to machine building, particularly, to production of split rings of hydraulic system ring valves. Ring billet is shaped to cylinder for fitting in valve seat at preset fit. Note here that billet from rolled thin-wall plate of spring steel is used and shaped to cylinder by clamping to mandrel cylindrical recess and quenching in oil. The billet medium-temperature tempering is performed at its setting.EFFECT: simplified process, lower labor input, longer life.3 dwg |
