Problems solved by technology

At present, this technology has not yet been able to achieve engineering application in our country. Our country has carried out a lot of research on this technology. One of the important technical problems is that during the finishing process of the overall blisk, the suspended blade part trembles after rough machining, which cannot be achieved. Processing qualified parts, especially larger parts, is more difficult to process later, which has become a difficult problem in the research of overall blisk processing technology

Abstract

The invention relates to a supporting filling material for producing an integral vane disk, which belongs to the material technical field, and comprises the components by weight percentage as follows: 68 to 90 percent of crystal paraffin, 9 to 32 percent of rosin glycerin ester, and 0.1 to 0.8 percent of 2, 6-di-tert-butyl p-cresol. By adopting the supporting filling material for producing the integral vane disk, the situation that the machining cannot be carried out because of tremor does not occur during the machining process, the accuracy of the machined vane size meets the needs, titanium alloy material is not eroded, the rigidity and the viscosity satisfy the machining requirements, the filling material is easy to clear out after machining, the obtaining method of the supporting filling material is simple, the filling operation is simple, convenient and easy, and the good popularization prospect is achieved.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a supporting filling material for manufacturing an integral blisk. Background technique [0002] The blisk manufacturing technology is one of the key technologies for the thrust-to-weight ratio of the aircraft power plant. The application of this technology reduces the weight of the original structure of the engine. At present, this technology has not been able to achieve engineering application in our country. Our country has carried out a lot of research on this technology. One of the important technical problems is that during the finishing process of the overall blisk, the suspended blade part trembles after rough machining, which cannot be achieved. It is more difficult to process qualified parts, especially larger parts, in the later stage of processing, which has become a difficult problem in the research of blisk processing technology. At present, my countr...
