Problems solved by technology

In practice, the higher the processing voltage, the higher the electrolysis efficiency. However, due to the large amount of heat generated in the processing gap and the formation of a large number of products, the processing stability is reduced, which restricts the processing efficiency of turbine blades. Therefore, how to operate at high voltage It is a technical problem that needs to be overcome at present to obtain a stable processing state

Abstract

The invention discloses a multi-tooth turbine blade precision electrolytic machining process, which relates to the technical field of turbine blade electrolytic machining, including the preparation of tool cathodes, the installation of tool cathodes, and the electrolytic machining of slub holes. The invention overcomes the limitations of traditional methods. Defects, it can still ensure the stability of the processing process under the condition of high voltage, thereby improving the efficiency of electrolytic processing and shortening the processing time. When the temperature of the electrolyte rises, the flow rate of the electrolyte can be adjusted by the adjustment module to accelerate The loss of heat in the electrolytic processing area achieves stable control of the temperature of the electrolyte.

Description

technical field [0001] The invention belongs to the technical field of electrolytic machining of turbine blades, and in particular relates to a precision electrolytic machining process for multi-tooth turbine blades. Background technique [0002] With the development of the aviation industry, the temperature of the turbine inlet is getting higher and higher, so higher requirements are put forward for the heat resistance of the blade material. At present, the cooling of the blade mainly adopts the circulation channels of different shapes inside the blade ( That is, the cooling channel) to increase the heat dissipation of the blade. As a high-efficiency and low-resistance blade cooling form, the ribbed cooling channel can be applied on the leading edge, blade pot, and blade back of the turbine blade. hole". During the heat transfer process of the "bamboo hole", the ribs on the side wall of the cooling hole have a greater disturbance to the fluid. This disturbance destroys the...
