Description

Technical Field

[0001] The utility model relates to the technical field of rounding tooling, in particular to a rounding tooling for impeller processing. Background Art

[0002] The impeller refers to the wheel disc with moving blades, which is a component of the impulse steam turbine rotor, and can also refer to the general term for the wheel disc and the rotating blades installed on it. The impeller can be divided into closed impeller, semi-open impeller and open impeller according to the shape and opening and closing conditions. The impeller is the core component of the water pump and the main factor affecting the working efficiency; the impeller is prone to overall structural deformation during the production and processing process, resulting in a decrease in the overall roundness of the impeller, which brings difficulties to the subsequent installation and use of the impeller. In order to ensure the roundness of the impeller after processing, the impeller needs to be rounded. The commonly used rounding method is to install the impeller on the fixture and then continuously hammer the surface of the impeller with a non-damaging hammer, but the entire installation process is relatively complicated and time-consuming;
