    摘 要
    薄壁異形件當前主要使用的是鋁合金材料,特別是在重要機載設備中的應用,比如航空航天設備,重工業設備等。所以為了減輕重量必須滿足薄壁前提,另外還必須要有一定的強度與硬度。如果使用它將多個根據電信微波信號發射器和接收器連接在一起,并且滿足設計要求位置的相互關系,達到所有要求以實現信號的發射與接收。因此加工此類零件必須要有一流的加工精度。關于鋁合金薄壁異形件種類的區別,可以參照它的大小、尺寸。用途不用,其結構形式也有很大的區別。關于鋁合金薄壁異形件種類的區別,可以參照它的大小、尺寸。用途不用,其結構形式也有很大的區別。總的來說鋁合金薄壁異形件的主要結構特點是:安裝孔加工精度要求要高;結構復雜、壁厚薄而且不均勻,沒有明顯基準面,形狀怪異;與其他鋼件相比,切削鋁合金材料后容易產生切削應力而導致材料變形等。
    零件表面層的物理和力學性能,對零件的使用性能與使用壽命有很大影響,提高和改善零件表面層的物理力學性能,因此,零件最終工序加工方法的選擇,應考慮該零件的具體工作條件及可能產生的破壞形式。同時從提高零件疲勞強度出發,同時考慮到零件可能受到交變應力作用,所以需要使用的加工方法最好是使零件產生殘余壓應力以避免產生殘余拉應力。該零件的加工精度要求較高,要求該零件加工精度高,加工表面的孔和平面,形狀,尺寸,位置都有要求,設計者需要周全考慮自身設計需求.所以使用專用工裝進行數控加工與設計可以在提高生產效率,減輕勞動強度,節約成本的同時有效的保證加工的精度。

    ABSTRACT

    Shaped pieces of aluminum alloy thin-walled main applications in the aerospace and machine a device, thus requiring the thickness of the wall, to achieve the purpose of weight reduction, and requires a certain strength, commitment, a matter of degree. Through the mutual position and assembled together, and then press the telecommunications design called for the launch of the microwave signal, and receives microwave spare parts. Therefore, the accuracy of the process of this type of spare parts have higher requirements. Aluminum alloy thin-walled shaped pieces of the type of its size, the size and structure of the use of different very different. Generally speaking, aluminum alloy thin-walled shaped pieces of the main structural features of the behavior of the gear hole machining accuracy requirements goatee complex structure, oddly shaped, there is no obvious base level; the degree of wall thickness, and asymmetry; aluminum alloy is prone to cut and slice shear force, compared with the general steel to cut lead to transformation.
    The accuracy of the process of spare parts a higher demand and the process of surface, mainly the peace in the square hole, the location, shape and dimensional accuracy, per a request. Process designed to take into account the cost savings, increased production to ease the labor intensity rate, therefore, the use of digital control, process and design funding package, you can effectively guarantee the accuracy of the scale of the process. A great influence on life of the use of functional and spare parts spare parts for the surface layer of the physical and mechanical properties, enhance and improve the physical and mechanical function of the surface layer of spare parts, spare parts, the final choice of the process approach should take into account the specific working conditions and possible output form of spare parts breakage. The transfer of spare parts to change to respond to the force function, improve the fatigue strength of spare parts set should be selected spare parts production and the remnants of the remaining press in order to avoid in the remaining forces to create a residual tensile response last.
    Keywords: thin-walled shaped machine to carry equipment
    The funding package tired strength weaken the rest of the force to pull That spare parts processes accuracy to have higher request and process noodles mainly is peaceful bore side, position, shape and size the accuracy Be all each to have a request. Technological design want in consideration of economize cost , raise rate of production, ease worker labor strength, therefore adopt a number to control to process and design the appropriation work packs, can availably promise that the size processes accuracy. The physical mechanics function of spare parts surface layer to usage function and service life of spare parts influences very greatly, the physical mechanics function of exaltation and the improvement spare parts surface layer, therefore, the spare parts end work preface processes the choice of method, should consider the concrete work condition and possible output breakage form of that spare parts . BE handed over to change in response to the spare parts of dint function from raising spare parts tired strength to set out, should choose to make the spare parts produced remnants remaining to press to avoid creation remnants in response to the dint remaining pulls in response to the a finally processing of the dint method.
    key words: Thin wall Abnormal shape The machine carries an equipments
    The appropriation work packs Tired strength Cripple remaining pulls in the response to the dint
