Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The processing method of sealing ring provided by the invention comprises the following steps:

[0033] (1) Four-way extrusion and wire drawing of the metal bar through the mold to obtain filamentous parts;

[0034] (2) Perform tempering heat treatment on the filamentous parts;

[0035] (3) Wind the wire-like parts into a spring shape to obtain the spring-like parts. The above-mentioned wire drawing refers to forcing the metal rod through the mold under the action of external force, the cross-sectional area of ​​the metal rod is compressed, and the required cross-sectional area is obtained. The process of area shape and size, in the present invention, the metal bar is stretched into elongated metal wire by wire drawing, and then the elongated metal wire is wound into a spring shape through a mold;

[0036] (4) Cut the spring-...

Abstract

The invention discloses a method for machining sealing rings. The method comprises the following steps of (1) carrying wiredrawing on metal bar materials, (2) carrying out heat treatment, (3) winding the wiredrawn metal bar materials into a spring shape, (4) cutting the metal bar materials into multiple twisted ring-shaped components with openings, (5) leveling the ring-shaped components, (6) carrying out quench tempering, (7) grinding the inner circumferential surfaces and the outer circumferential surfaces of the ring-shaped components so that the inner circumferential surfaces and the outer circumferential surfaces of the ring-shaped components can be regular arcs, (8) opening the openings of the ring-shaped components to a preset size and then carrying out heat shaping, (9) obtaining the formed sealing rings. According to the method for machining the sealing rings, material waste is quite low, the machined sealing rings are high in strength, toughness and elasticity and uniform in wall thickness, the thermal elastic loss and the residual deformation of the machined sealing rings are both small, latent defects of the sealing rings can be exposed in the early stage of machining, and the sealing rings with the latent defects can be picked out.

Description

technical field [0001] The invention relates to a processing method for a sealing ring of a turbocharger. Background technique [0002] When the turbocharger is working, the turbine shaft runs at a high speed at a speed of tens of thousands to hundreds of thousands of revolutions per minute. Therefore, the bearings matched with the turbine shaft need to be lubricated with high-pressure circulating lubricating oil, and the sealing ring is installed on the turbine shaft. The end of the shaft acts as a seal for the lubricating oil. The seal ring not only needs to withstand high temperature and high pressure, but also needs to withstand high-frequency vibration, so the mechanical properties and machining accuracy of the seal ring are required to be high. [0003] In the prior art, the sealing ring is generally processed from a thicker metal bar, and the processing process is as follows: (1), the metal bar is rough-turned and then axially drilled, and the metal bar is processed i...
