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 precise electrolytic machining process for a multi-tooth turbine blade, and relates to the technical field of electrolytic machining for turbine blades. The precise electrolytic machining process for the multi-tooth turbine blade comprises the steps of preparation for a tool cathode, installation for the tool cathode, electrolytic machining for a bamboo joint hole and the like. According to the invention, the defects of a traditional method are overcome, and under the condition of high voltage, the stability of the machining process can still be guaranteed, so that the electrolytic machining efficiency is increased, and the machining time is shortened; and when the temperature of an electrolyte rises, the flow speed of the electrolyte can be adjusted through an adjusting module so as to accelerate heat dissipation of an electrolytic machining area, so that stable control over the temperature of the electrolyte is achieved.

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...
