Abstract

The invention discloses a high speed extrusion forming mold of a blade. The high speed extrusion forming mold of the blade comprises a blade basin mold and a blade back mold, wherein the blade basin mold and the blade back mold are manufactured according to the following steps: step A, according to data of the theoretical blade profile of the blade part, selecting a plurality of characteristic sections from the blade body portion, and obtaining a basic blade basin curve and a basic blade back curve of a corresponding characteristic section of a new blade blank after adding allowance accordingto 3%-5% of the maximum thickness of the blade body portion of the theoretical blade profile in the normal direction for each characteristic section of the theoretical blade profile; step B, obtaininga final blade basin face and final parameters of the corresponding characteristic sections of the new blade blank from all the characteristic sections of the new blade blank obtained in the step A; step C, obtaining continuous and complete profile surfaces and parameters of the blade body portion of the new blade blank; and step D, designing and manufacturing the blade basin mold and the blade back mold. The high speed extrusion forming mold of the blade can reduce reserved allowance of the blade blank.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a mold for manufacturing blade blanks by using a high-speed extrusion molding process in the process of manufacturing aeroengine blades. Background technique [0002] The blade is one of the important parts of the aero-engine. For the blade, the accuracy of the surface size of the airfoil is very important. The compressor blade is located near the air inlet of the aero-engine. This type of blade is generally made of blade blank by forging forming process, and then enters the subsequent process for precision machining (including electrolysis, digital milling, polishing and other processing operations). [0003] figure 1 It is a schematic diagram of the process principle of high-speed extrusion of the blade; figure 2 for figure 1 The schematic diagram of the cross-sectional structure of the airfoil part of the forming female die, in order to facilitate the expression of the pos...
