Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The present invention provides a method for designing and optimizing the processing trajectory parameters of the integral blisk electrolytic preliminary forming, which includes the following steps:

[0037] Step 1: Drive the processing tool to feed along the radial direction of the blisk, and electrolytically pre-process the cascade gap between the blades on the blisk according to the processing trajectory parameters;

[0038] Step 2: Drive the overall blisk to rotate clockwise / counterclockwise around its central axis, and bring the blade basin profile / blade back profile of the processing head closer to the correspon...

Abstract

The invention is suitable for the technical field of electrolytic machining, and provides a design optimization method for blisk electrolytic preforming machining track parameters. A blade back and ablade basin of every two adjacent blades are subjected to electrolytic machining through a machining tool, then one machining head simultaneously has a blade basin profile surface and a blade back profile surface, the relative positions of the blade basin profile surface and the blade back profile surface are determined and are invariable, and it can be guaranteed that the relative positions of the electrolytic machining forming surfaces of the blade basins and the blade backs of the blades are stable and invariable only enabling the machining tool to run to the set position; and meanwhile, the machining track parameters are optimized, and design of the blisk electrolytic preforming machining track parameters is quickly completed. Therefore, the blisk machining and manufacture cost is low,the efficiency and the precision are high, the machining optimization method is simple, and the machining requirements of aero-engines in the military and civil fields are met.

Description

technical field [0001] The invention relates to the technical field of electrolytic machining, in particular to a method for designing and optimizing machining trajectory parameters of integral blisk electrolytic preliminary forming. Background technique [0002] Electrolytic machining is a special process method that uses the principle of electrochemical anodic dissolution to realize metal removal. It has the characteristics of high processing efficiency, no consumption of tool electrodes, no stress in processing, and good surface integrity. It is suitable for processing various difficult-to-cut metal materials, especially for processing various three-dimensional complex shapes. [0003] The performance of the aero-engine directly affects the flight performance, reliability and economy of the aircraft. It is called the "heart" of the aircraft. As an important structural part of the fourth-generation engine, the overall blisk adopts an integrated structure to replace the con...
