Abstract

The invention belongs to the technical field of precision machining, and discloses a polishing method for a multi-element flow blade profile. The polishing method comprises the following steps that 1)a wood wheel is adopted for grinding and removing the excessive amount of a through connection R, the front edge and the rear edge of a blade, and a louver wheel grinding head with a handle is adopted for polishing milling residual lines on a blade basin and a blade back of the blade; 2) a fiber wheel is adopted for polishing the through connection R, the front edge, the rear edge and the blade back of the blade, and then a medium-hard nylon fiber wheel is adopted for polishing the blade basin of the blade, and a soft nylon fiber wheel is adopted for polishing the blade basin of the blade; and 3) after fine polishing is completed, a process boss is cut off through linear cutting, and the multi-element flow blade is obtained. Special treatment is carried out at different requirement stagesof blade polishing through different polishing tools, and damage to the surface of the blade and the air inlet and outlet edges can be reduced while the polishing requirement is met.

Description

technical field [0001] The invention belongs to the technical field of precision machining, and relates to a polishing method for the profiles of multiple flow blades. Background technique [0002] Blades are a very important type of parts in industrial manufacturing and play a key role in the performance of products. Product efficiency, service life and other indicators are directly affected by the design and manufacturing quality of the blades, and are the main influences. In particular, the blades in the field of precision machining are very important to the performance of the product, because most of the blades in this field are irregular in shape, and the size calculation is complicated, which is very different from ordinary parts. [0003] The multi-flow blade surface and its inlet and exhaust edges are polished to ensure the processing quality of the blade. Due to the small size of the blade and the complex shape of the blade, the distortion of the blade pot is very ...
