Embodiment Construction

[0041] The iterative method for the cathode of double-journal blade precision electrolytic forming based on deformation control of the present invention first needs to carry out the detection data after the process verification based on the initial surface of the forming cathode, and then iterates the deformation amount explored in the iterative process, and finally Obtain the cathode profile after iteration. The molded cathode profile is a pair of working cathodes with three-dimensional curved surfaces.

[0042] The three-dimensional curved surface working cathode is a tool for electrolytic forming of blades. The initial profile of the working cathode can be designed according to the different shapes of the blade parts, according to the COS rule, and the initial profile of different shapes is calculated through gap calculation to ensure the initial processing of the blade profile. molding precision. After multiple experiments and optimization, the full-surface blue-ray three...

Abstract

The iterative method for precision electrolytic forming cathodes of double journal blades based on deformation control of the invention belongs to the technical field of aero-engine blade processing. The deformation amount is iterated in, and finally the iterative cathode profile is obtained. By adopting the cathode iterative method of the present invention, the problem of deformation of the blade after processing can be offset, so as to realize the precise electrolytic processing without margin of this type of blade.

Description

technical field [0001] The invention belongs to the technical field of aero-engine blade processing, and relates to a cathode iteration method for precise electrolytic forming of double-journal blades based on deformation control. Background technique [0002] The principle of electrolytic machining is a non-traditional cutting method that uses the principle that metals can undergo anodic dissolution in the electrolyte to remove materials and shape workpieces. In electrolytic machining, the tool (knife) is connected to a DC power source as the cathode and the workpiece as the anode. In the electrolyte, the cathode of the tool moves to the anode of the workpiece at a certain speed, and the charge exchange occurs between the tool and the workpiece. The material of the anode workpiece is dissolved and taken away by the high-speed flowing electrolyte, thereby achieving very precise processing requirements. [0003] At present, for the current dominant process of double journal ...
