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
