Novel integral turning method of blades

Abstract

The invention provides a novel integral turning method of blades, which can effectively solve the problem of insufficient pressing force of the blades during the assembly machining of the blades in the past and also overcome the defect of insufficient rigidity caused by interrupted cutting. The novel integral turning method of the blades is simple and can greatly enhance machining efficiency. The novel integral turning method of the blades is characterized by comprising the following steps of: positioning the blades by simulating an assembling state, and pressing the positioned blades on a turning jig by using a press plate; then pouring a low-melting-point alloy between the blades and the turning jig; disassembling the press plate after the low-melting-point alloy is cooled and solidified; firmly bonding the blades and the turning jig depending on the low-melting-point alloy so that an integral rigid part is formed by the blades and the turning jig, and then carrying out assembly machining on the blades; and after the blades are subjected to the assembly machining, placing the blades and the turning jig into hot water so that the blades and the turning jig are separated because the solid low-melting-point alloy is melted when heated, and therefore the assembly machining of the blades is completed.

Description

technical field [0001] The invention relates to the technical field of blade processing, in particular to a novel integral turning method of blades. Background technique [0002] Under normal circumstances, the blades of the engine group are combined and processed by pressing each part of the blade one by one, and the processing parts are avoided by replacing the pressure plate during the processing process, that is, the crown is pressed when the root is processed, and the root is pressed when the crown is processed. Because it is interrupted cutting rather than continuous cutting, it has the problem of insufficient pressing force, and it is easy to generate noise, joint marks, and insufficient rigidity during the cutting process. In order to solve the above-mentioned problem of insufficient rigidity, wooden wedges are generally installed between the combined blades to support the rigidity of the blades. However, because the blade surface is a three-dimensional curved surfac...
