Method for preparing turbine sealing ring from alloy wire

Abstract

The invention provides a method for preparing turbine sealing rings through an alloy wire rod. The method includes the steps that a round wire rod with chemical components conforming to the characteristics of the sealing rings is selected, and the round wire rod is mechanically ground to have a rectangular section and wound to be in a spring shape; cutting is conducted according to the center line of the spring-shaped workpiece, and multiple sealing ring preliminary rings are obtained; the preliminary rings are fed into a hardening furnace, when the preliminary rings are gradually heated to a critical point along with the furnace, heat is preserved for 0.5-2 h, and then the preliminary rings are delivered out of the furnace to be subjected to air cooling or oil cooling; then a tempering procedure is executed, in other words, after iron sheets with the thickness consistent with that of designed free openings are inserted into the openings of the hardened preliminary rings, the preliminary rings are fed into a tempering furnace to be gradually heated to a critical point along with the furnace, heat is preserved for 1.5-4 h, then the preliminary rings are delivered out of the furnace to be subjected to air cooling, and then the preliminary rings with the tempering hardness requirements of the free openings conforming to the design requirements are obtained; and then grinding and premise external grinding are conducted. The method has the advantage that the defects that sealing rings are relatively low in percent of pass and low in yield due to a backward manufacturing process of the sealing rings, and material cost and labor cost are wasted can be overcome.

Description

technical field [0001] The invention relates to the technical field of turbocharger sealing rings, in particular to a preparation process for manufacturing a turbine sealing ring from a novel alloy wire, that is, a method for preparing a turbine sealing ring from an alloy wire. Background technique [0002] The sealing ring is one of the important parts of the turbocharger, and it is widely used in the oil and gas sealing of the turbocharger of the diesel internal combustion engine and gasoline engine. [0003] With the rapid development of science and technology today, the demand for cars and machines using similar engines is also increasing. As a result, the market demand for sealing rings has been driven, but as a sealing ring manufacturer, it is generally necessary to continue to practice the traditional manufacturing process, that is: configure according to the required chemical composition, smelt and cast alloy bars to obtain raw materials for sealing rings; and then u...
