Waterjet turbocharger: Process design of bearing end cover:

Both the end surface and the inner and outer circular surfaces of the bearing end cover require turning processing. Semi-finishing and roughing can be used, and the roughing and finishing should be carried out separately to ensure the surface roughness requirements. The main bearing end cover process design is as follows:

1. Aging treatment of the workpiece

For the parts whose blanks are castings, due to the uneven thickness of each part, there are large casting internal stresses, which are easy to cause defects such as deformation, so artificial aging treatment must be arranged. For this end cover, the accuracy requirements are general, and the natural parking and transportation time between roughing and finishing processes can be used to obtain the effect of natural aging treatment. The longer the natural aging treatment, the better, otherwise it will affect the stability of the end cap fitting accuracy. For particularly precise end caps, an artificial aging should be arranged between the roughing and finishing processes to eliminate the internal stress of the casting and improve the accuracy and stability.

2. The order of the processing technology should be face first and then hole

As the main two types of machining surfaces on the end caps, planes and holes, from the perspective of stable and reliable positioning, planes are much superior to holes, and at the same time, the machining allowance of the holes can be made uniform; from the perspective of processing difficulty, planes It is easier to process than holes; from the analysis of favorable processing, the holes distributed on the plane are processed after the plane is processed first. Because the defects such as unevenness and sand inclusion on the surface of the casting have been removed, it is greatly beneficial to the process of hole processing.

3. Separate rough and fine processing in the processing stage

The end cover is a cast iron piece, and the reserved machining allowance is large. In rough machining, the cutting allowance is large, the clamping force and cutting force are large, and there is more heat removal, so it has a greater impact on the machining accuracy; In addition, rough machining is cutting the surface metal of the blank, and the internal stress of the workpiece is redistributed, which will also cause the workpiece to deform. Therefore, roughing and finishing are divided into two processing stages, which is conducive to fully exposing the deformation of the workpiece due to various reasons after roughing, and it can be eliminated in the finishing stage.

4. Cleaning of the workpiece

At the same time, the cleaning step is also very important. Cleaning is of great significance for ensuring the quality of machine assembly and prolonging the service life of the machine, especially for precision fittings and seals. The purpose of cleaning is to remove oil and impurities on the surface of the parts. Commonly used cleaning fluids include kerosene, gasoline, lye and chemical cleaning fluids, etc. When cleaning, scrubbing, dipping, spraying and ultrasonic cleaning can be used.
