Description
Technical field
The present invention relates to hollow turbine vane blade blanking cover renovation technique, belong to blade of aviation engine manufacturing technology field.
Background technology
At present, existing hollow turbine vane blade blanking cover renovation technique mainly adopts electric pulse and lead plug, this technique practical operation is got up very difficult, and while getting blanking cover can to blade cause in various degree touch scuffing, the remediation efficiency of blade blanking cover only has about 20%, and the qualification rate after repairing only has 10 ￣ about 20%, has had a strong impact on the Leaf productivity of factory.
Summary of the invention
The object of the present invention is to provide hollow turbine vane blade blanking cover renovation technique, overcome the deficiencies in the prior art, blade blade blanking cover can be realized and repair simple and easy to do, improve the efficiency of blade blanking cover reparation and the technique of qualification rate.
The object of the invention is to be achieved through the following technical solutions: hollow turbine vane blade blanking cover renovation technique, it comprises following steps:
(1) preparation fix tool, is made: fix tool comprises spherical mounted point, conical grinding wheel, band point stock, buckle stock, pliers and tup, the spherical mounted point matched according to structure fabrication and the blanking cover size of hollow turbine vane blade blanking cover and conical grinding wheel, be with sharp stock and buckle stock to be that 45 steel pass through forging forming;
(2), the polishing of hollow turbine vane blade blanking cover: blade and blade has been worn and torn the inwall of blanking cover and bottom even polishing with it, until it is thinning with spherical mounted point;
(3), on the blade blade blanking cover thinned open osculum: on the inwall of blanking cover, open an osculum with conical grinding wheel, after punching press, form lageniform huge tension force to eliminate blanking cover;
(4), to the blanking cover of blade blade destroy: the tip of the sharp stock of band is against on the contact point of blanking cover and blade, beats gently with tup, until whole blanking cover is deformed destruction;
(5) blanking cover of deformation failure, is taken out: gone out by the blanking cover of deformation failure hook gently with hook-type stock, be exposed to outside blade blade plug-hole as much as possible to make the blanking cover of deformation failure, with the distortion blanking cover outside the pliers clamping plug-hole that band is most advanced and sophisticated, firmly press from both sides out the blanking cover of whole distortion;
(6), more renew blanking cover, complete the reparation to blade blade blanking cover.
Described spherical mounted point and the surface of conical grinding wheel are provided with and scribble Buddha's warrior attendant abrasive particle.
Beneficial effect of the present invention is: adopt spherical mounted point, conical grinding wheel, be with sharp stock, buckle stock, the simple reparing process such as pliers and tup, practical operation is got up than being easier to realization, common workman just can repair, for factory has saved a large amount of capitals, be significantly improved with existing renovation technique phase specific efficiency and qualification rate simultaneously, remediation efficiency improves more than 50%, the qualification rate of repairing brings up to more than 95% by 10% ￣ 20%, achieving blade blade blanking cover repairs simple and easy to do, improve the efficiency of leaf body blanking cover reparation and the technique of qualification rate.

Detailed description of the invention
Technical scheme of the present invention is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
Hollow turbine vane blade blanking cover renovation technique, it comprises following steps:
(1), as Fig. 1, make and prepare fix tool: fix tool comprises spherical mounted point 1, conical grinding wheel 2, is with sharp stock 4, buckle stock 5, pliers 6 and tup 3, the spherical mounted point 1 matched according to structure fabrication and the blanking cover size of hollow turbine vane blade blanking cover and conical grinding wheel 2, be with sharp stock 4 and buckle stock 5 to be that 45 steel pass through forging forming;
(2), as Fig. 2, the polishing of hollow turbine vane blade blanking cover: with inwall and the bottom even polishing of the blanking cover that weares and teares on spherical mounted point 1 pair of blade blade 8, until the thin blanking cover 7 of its thinning formation;
(3), as Fig. 3, the blade blade blanking cover thinned opens osculum: on the inwall of thin blanking cover 7, open an osculum 9 with conical grinding wheel 2, after punching press, form lageniform huge tension force to eliminate blanking cover;
(4), as Fig. 4, the blanking cover of blade blade is destroyed: the tip of the sharp stock 4 of band is against thin blanking cover 7 with on the contact point of osculum 9, beats gently with tup 3, until whole thin blanking cover 7 is deformed destruction;
(5), as Fig. 5, Fig. 6, take out the blanking cover of deformation failure: go out with thin blanking cover 7 hook gently of hook-type stock 5 by deformation failure, be exposed to outside the plug-hole of blade blade 8 as much as possible to make the thin blanking cover 7 of deformation failure, clamp the thin blanking cover 7 of the deformation failure outside plug-hole again with the pliers 6 that band is most advanced and sophisticated, firmly press from both sides out the thin blanking cover 7 of whole deformation failure;
(6), more renew blanking cover, complete the reparation to blade blade blanking cover.
Described spherical mounted point 1 and the surface of conical grinding wheel 2 scribble Buddha's warrior attendant abrasive particle.
