Problems solved by technology
[0002] At present, the existing hollow turbine blade airfoil cover repair process mainly adopts electric pulse and drilling pin, which is very difficult to operate in practice, and will cause different degrees of scratches to the airfoil while removing the cover. The repair efficiency of blade body plugging is only about 20%, and the qualified rate after repair is only about 10~20%, which seriously affects the blade production efficiency of the factory

[0020] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0021] Hollow turbine blade airfoil plugging repair process, which includes the following steps:
[0022] (1), such as figure 1 , Prepare repair tools: repair tools include spherical grinding head 1, conical grinding head 2, pointed long rod 4, hooked long rod 5, pliers 6 and hammer head 3, which are made according to the structure of the hollow turbine blade blade cover The spherical grinding head 1 and the conical grinding head 2 matching the size of the plug cover, the pointed long rod 4 and the hooked long rod 5 are made of 45 steel and formed by forging;
[0023] (2), such as figure 2 1. Grinding of the hollow turbine blade airfoil cover: use a spherical grinding head 1 to evenly polish the inner wall and bottom of the worn cover cover on the blade airfoil 8 until it becomes thi...

The invention discloses a process for repairing a hollow turbine blade body blocking cover. The process comprises the steps of manufacturing and preparing repairing tools, grinding the hollow turbine blade body blocking cover, forming a small opening in the thinned blade body blocking cover, damaging the blade body blocking cover, taking out the deformed and damaged blocking cover, and replacing the deformed and damaged blocking cover with a new blocking cover. The process has the advantages that the simple repairing tools such as a globe grinding head, a conical grinding head, a long sharp rod, a long hooked rod, a clamp and a hammer are adopted, the actual operation is relatively easy to achieve, a common worker can conduct repairing, a large amount of capital is saved for a factory, and meanwhile compared with an existing repairing process, the efficiency and the qualified rate are obviously improved; the repairing efficiency is improved by more than 50 percent, the repairing qualified rate is improved to more than 95 percent from 10 percent to 20 percent, the convenient and easy repairing of the blade body blocking cover is achieved, and the repairing efficiency and the qualified rate of the blade body blocking cover are improved.
Description
technical field [0001] The invention relates to a hollow turbine blade airfoil plugging repair process, and belongs to the technical field of aeroengine blade manufacturing. Background technique [0002] At present, the existing hollow turbine blade airfoil cover repair process mainly adopts electric pulse and drilling pin, which is very difficult to operate in practice, and will cause different degrees of scratches to the airfoil while removing the cover. The repair efficiency of blade body plugging is only about 20%, and the qualified rate after repair is only about 10~20%, which seriously affects the blade production efficiency of the factory. Contents of the invention [0003] The purpose of the present invention is to provide a hollow turbine blade airfoil cover repair process, which overcomes the shortcomings of the prior art, can realize the simple and easy repair of the blade airfoil cover cover, and improves the efficiency and qualified rate of the airfoil cover r...
