Abstract

The invention discloses a bending machining technique method for a turbine blade. The bending machining technique method for the turbine blade comprises the following steps that a, a stainless steel sheet is chosen, an outer contour blank piece of the turbine blade is prefabricated, and the overall length demand of the outer contour blank piece is guaranteed; b, a lower mould structure of a manufactured bending and forming mould is fixedly arranged on a machine tool, and the other corresponding moving mould is an upper mould structure; c, the blank piece of the turbine blade is clamped on the bending and forming mould; d, the blank piece is subjected to a squeezing bending and forming process by the bending and forming mould, the other end of the blank piece is subjected to bending and forming operations with one end of the blank piece as the standard, forming machining of the blank piece is achieved, and the blank piece is bent till the radian and angle meet the requirements; and e, after machining is finished, the blank piece is detached from a clamp of the bending and forming mould, and a finished product is obtained. According to the bending machining technique method for the turbine blade, the problem of bending head straining is solved, the condition that multiple blades are simultaneously and continuously machined by one set of mould is achieved, production efficiency is high, surface quality is good, machining is stable and reliable, and the bending machining technique method is suitable for batch production.

Description

technical field [0001] The present invention relates to the technical field of manufacturing turbine blades, in particular to a bending process method for turbine blades. Background technique [0002] With the continuous development of science, parts such as turbine blades are used in various aspects of the aerospace field, such as aerospace vehicle parts, missile parts and ship parts. Turbine blade is a special part, which has a large number, complex shape, high requirements, difficult processing, and frequent failures. Therefore, its manufacturing and processing has always been the key link of various production and processing enterprises. The commonly used process for the bending of existing turbine blades is to use a mold with a guide post for bending. Using this mold for processing, in the case of a large number of processing, the blade head is prone to relatively large scratches and strains, especially 90 Angles often go wrong, resulting in processed parts that do not...
