Study On Fan Blade & Curving Mould Based On UG NX Software

Axial-fan has a long history, it has the features as small volume,low pressure with big flux.It is mainly used in the following industries as metallurgical,mining, textile, electricity and so on. In the airiness systems of mining, axial fans are used in blowing away gases and lowering the thickness of gas in the mine. The degree of airiness can affect the safety of production and personal security directly. At present, mining fans are developing in a way of high efficiency and low noise.For the sake of the complicated tri-dimension fluxion in axial fan, it is very difficult to describe the condition of separate and its back fluxion of blade surface accurately. So during the practical process of making and designing axial fans, many mining manufacturers exist blindness by experience especially in choosing the type of blade surface.Jiangxi Southern Coal-Mining Fan Factory produces mining separate explosion axial fans.They still use the traditional methods to design fans which is mainly by hand. Especially in the process of designing and making blades, there are a lot of parameters variables, it is difficult to calculate, with the uncertainty of some parameter, this leads to the result of long period of designing, so it is difficult to meet the market requirements.This article are based on the theory of axial-fan designing, aiming at the designing process of the pivotal part—blades which is using advanced CAD/CAM software UG NX6.0 to analyze and sculpt the blades, after processing, numerical maching blade curving mould surface, and then use the mould to produce the blade products, and check the effect of airiness and lowering noise of the product. In order to realize the quick designing, producing axial-fan blade mould, it has brought much convenience in designing fans, and shortened the period of design and manufacturing and so it has important practical and engineering significance in promoting the advantages of the products'market competitive power.
