Embodiment Construction

[0066] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0067] A method for judging and adjusting during blade rolling, comprising the following steps:

[0068] Step 1: Judgment and adjustment of bite position,

[0069] Step A: Use a caliper to measure the size of the bite position, and judge whether it meets the size set on the process drawing. If not, adjust it to meet the process requirements;

[0070] Step B: Measure the profile of the blade with a large twist angle blade, and compare the profile measurement result with the theoretical profile;

[0071] Step C: If there is a difference in the position of the exhaust edge of the blade along the bending angle of the longitudinal section of the airfoil, such as figure 1 , figure 2 As shown, it needs to be adjusted by changing the bite position;

[0072] Step D: Comparing and analyzing the measurement data to obtain the adjustment amo...

Abstract

The invention discloses a judging and regulating method for a blade rolling process, belonging to the technical field of aviation engine blade rolling. The method is rapid, accurate and capable of greatly shortening the regulating time, shortening the repair period of a rolling die, reducing the consumption of die repairing test blocks and manpower and ensuring that a blade meets the requirement of a design drawing to the maximum extent. The judging and regulating method comprises the following steps of firstly, judging and regulating a seaming position; secondly, judging profile offsetting and twisting; thirdly, judging and regulating die profile air inlet and exhaust side direction translation; fourthly, judging and regulating blade rotation around the vertical direction; fifthly, judging and regulating a blade along the vertical direction; sixthly, judging and regulating blade rotation around a horizontal shaft; and seventhly, judging and regulating blade rotation around a central line of a blade body.

Description

technical field [0001] The invention belongs to the technical field of rolling processing of aeroengine blades, and in particular relates to a judgment and adjustment method in the rolling process of blades. Background technique [0002] Precision cold rolling of blades without margin is an advanced blade surface processing method, which has attracted the attention of developed countries due to its low manufacturing cost, high production efficiency, and the fact that the structure and performance of the product can be better than conventional manufacturing processes. . In this regard, the manufacture of high-pressure compressor blades for new engines represented by major Russian aero-engine manufacturing companies is almost entirely based on the "precision wool + rolling without margin" process. [0003] During the blade rolling process, due to the difference in the initial state of the rolling mill, the design and manufacturing level of the rolling die, the design and prep...
