Heat treatment process for rotor spindle of supercharger

Abstract

The invention relates to a heat treatment process for a rotor spindle of a supercharger. The heat treatment process comprises the following the technological steps: (1) firstly placing a rotor spindle workblank welded by friction welding to a tempering furnace; (2) setting the temperature of the tempering furnace to be 500-600 DEG C and tempering the workpiece in the tempering furnace for 2.5-3.5 hours; and (3) after the tempering is completed, placing the workpiece in the environment of normal temperature to naturally cool. The problem of chip shell of the rotor spindle produced by adopting the heat treatment process is obviously improved, the chip shell ratio is reduced to 1 per thousand from original 0.5%, wheel head materials of K18 and K13 can be distinguished by the naked eyes, manpower is saved, loss to a company is reduced, and the service life is also prolonged.

Description

technical field [0001] The invention relates to a supercharger rotor shaft heat treatment process. Background technique [0002] Before the improvement, due to the low tempering temperature of the supercharger rotor shaft heat treatment, some rotor shafts had blade drop problems, which damaged the company's image; in the past, the rotor shafts were often made of different materials, but they could not be distinguished when put together. In terms of cost, it is impossible to determine the correct cost of a piece of work, which leads to the phenomenon that the company's products are high in and low in output, thus affecting profits. Contents of the invention [0003] The object of the present invention is to provide a supercharger rotor shaft heat treatment process in order to overcome the defects and deficiencies in the above-mentioned prior art. [0004] The technical solutions adopted are: [0005] The supercharger rotor shaft heat treatment process is characterized in ...
