Description
Technical field
The present invention relates to brush seal (obturaging), particularly a kind of automatic row's silk machine of the brush seal installation for make reducing aero-engine secondary stream air loss and make the method for brush seal installation with this row's wire feed mechanism.
Background technology
Brush seal is a kind of new technology that can significantly reduce aero-engine secondary stream air loss, and brush seal installation used is the simplest, the most practical, the most effective regeneration product of comb tooth sealing of continuing to use for many years.Practical application shows, only at aero-engine one place or several places key position adopt brush seal to replace the sealing of comb tooth, just can make the thrust of engine improve 1%～3%, fuel consume decline 3%～5%.Therefore, adopt the brush seal technology can significantly improve the performance of engine.
The structure of brush seal installation is divided into Welding Structure and panel beating attaching type structure.Be subjected to the restriction of technical conditions, the aero-engine brush seal installation used that China produces at present also all adopts Welding Structure.
The domestic air mail engine building is made welded brush seal installation and is all adopted manual row's silk, and its production efficiency is low, and labour intensity is large, and crudy is unstable.In manual row's silk process, need to twine silk, make the brush bundle, arrange the operations such as brush bundle, not only the time is long, work is loaded down with trivial details, and difficult quality control, is subjected to artifical influence factor more.The brush ring that manual row's silk is made is lower in aspect precision such as row's silk angle, brush silk total quantity, brush silk uniformities, directly affects quality and the result of use of brush seal.
The applicant once disclosed a kind of brush seal installation manufacture method that adopts craft to combine with special tooling in the CN101430007B patent application.Though the method can improve to a certain extent work efficiency and reduce labor intensity, but remain in many defectives: the one, required operation more (comprise twine silk, make the brush bundle, arrange the brush bundle, assembling and welding brush ring etc.), and operation is numerous and diverse, expends man-hour more, is prone to quality problems; The 2nd, precision hand-manipulated is difficult to guarantee, as mentioned above, arranges the control of silk angle, the control of brush ring brush silk total quantity, a brush uniformity control etc. and is affected by human factors, unstable product quality; The 3rd, production efficiency is still lower, and labor strength is still larger.
Summary of the invention
The objective of the invention is the defective for above-mentioned prior art existence, a kind of method that can replace manually realizing row's silk machine of automation row silk and make brush seal installation with this row's wire feed mechanism is provided, for alleviate labor strength, improve production efficiency and product quality creates conditions.
