【摘要】：在航空發(fā)動(dòng)機(jī)中,葉片起著能量轉(zhuǎn)換的關(guān)鍵作用,是發(fā)動(dòng)機(jī)的“心臟”。作為發(fā)動(dòng)機(jī)的重要部分,葉片的質(zhì)量對(duì)發(fā)動(dòng)機(jī)影響巨大。由于葉片的品種多、數(shù)量大、材料切削性能差、型面復(fù)雜、技術(shù)要求嚴(yán)格,使得其工藝及生產(chǎn)準(zhǔn)備周期長(zhǎng)、制造工藝復(fù)雜、制造工藝方法不統(tǒng)一。國內(nèi)研制機(jī)種的壓氣機(jī)轉(zhuǎn)子葉片的試制主要以批產(chǎn)葉片的制造工藝方法為基礎(chǔ)進(jìn)行制造,這樣不僅需要派制大量的工裝,而且工藝及生產(chǎn)準(zhǔn)備周期長(zhǎng),一旦設(shè)計(jì)圖紙發(fā)生變化,需重新編制工藝規(guī)程并會(huì)造成大量的工裝報(bào)廢。本文以某型機(jī)壓氣機(jī)轉(zhuǎn)子葉片為例,重點(diǎn)針對(duì)葉片加工的核心內(nèi)容——葉片的技術(shù)要求、毛坯制造工藝和葉片加工工藝等進(jìn)行系統(tǒng)化的探討、研究。葉片的制造工藝水平直接影響著其榫頭和葉身型面的質(zhì)量。本文研究了某機(jī)轉(zhuǎn)子葉片兩種工藝路線對(duì)加工質(zhì)量和效率的影響,最終制定了一種一次裝夾,一體化加工的工藝路線。通過設(shè)計(jì)合理的裝夾方式和穩(wěn)定的夾具系統(tǒng),提高了葉片數(shù)控加工系統(tǒng)的整體剛性。并在制造全過程中應(yīng)用數(shù)字設(shè)計(jì),數(shù)字制造,數(shù)字檢測(cè)的自動(dòng)化技術(shù),改變了傳統(tǒng)工藝加工模式,提高了產(chǎn)品質(zhì)量,加快了新產(chǎn)品的開發(fā)速度。本文還介紹了葉身型面精密數(shù)控銑削加工的方法,分析了高溫合金薄型葉片在加工過程中的變形影響因素及如何加以控制,并且依據(jù)葉片的批量測(cè)量結(jié)果,通過改進(jìn)切削方式、切削參數(shù)以及模型等手段,在模型和加工程序上加以調(diào)試及補(bǔ)償,最大限度地減小了葉片變形,達(dá)到了數(shù)控切削的工藝精度要求。本文的研究結(jié)果已成功應(yīng)用于航空發(fā)動(dòng)機(jī)新機(jī)科研葉片的小批量快速研制、精密加工及檢測(cè)中,縮短了新機(jī)葉片的制造周期。
[Abstract]:In aero-engines, blades play a key role in energy conversion and are the "heart" of the engine. As an important part of the engine, the quality of the blade has a great impact on the engine. Due to the variety of blades, large quantity, poor cutting performance, complex profile and strict technical requirements, the process and production preparation period is long, the manufacturing process is complex, and the manufacturing process is not uniform. The trial production of compressor rotor blades developed in China is mainly based on the manufacturing process of batch production blades. In this way, not only a large number of tooling is required, but also the process and production preparation period is long. Once the design drawings change, Process procedures need to be reworked and a large number of tooling will be scrapped. In this paper, the rotor blade of a compressor is taken as an example. The technical requirements of blade, blank manufacturing technology and blade processing technology are studied systematically. The manufacturing process level of blade directly affects the quality of its tenon and blade body surface. In this paper, the influence of two kinds of technological routes on the machining quality and efficiency of a certain rotor blade is studied, and a process route of once clamping and integrated machining is worked out. By designing reasonable clamping mode and stable fixture system, the overall rigidity of blade NC machining system is improved. The automation technology of digital design, digital manufacturing and digital detection is applied in the whole manufacturing process, which changes the traditional processing mode, improves the product quality and speeds up the development of new products. This paper also introduces the method of precise NC milling of blade body surface, analyzes the influence factors and how to control the deformation of thin superalloy blade in the process of machining, and according to the result of batch measurement of blade, improves the cutting method. The cutting parameters and the model are debugged and compensated in the model and machining program to minimize the blade deformation and to meet the precision requirements of NC cutting. The research results in this paper have been successfully applied to the rapid development of aeroengine new engine blades in small batch, precision machining and testing, thus shortening the manufacturing cycle of the new engine blades.
