Abstract：

In order to gain higher pressure, the centrifugal blower is often the ideal choice.The integral structure accomplished by five mold processes was used for the centrifugal blower impeller(material of aluminium sheet L1060) to get the overall strength when rotating rapidly，which broke through the traditional combined structure. In order to ensure the equal degree and consistency of the 36 blades, the impeller side notch was completed by a pair of convex and concave dies. With the help of the 36 aliquots technological hole of impeller drawing technology flange, the equal precision of punched 36 blades was ensured by location mode of one side with two pins . In order to effectively solve the demoulding problem of impeller side notch after bending, the impeller floating demoulding mechanism was used successfully. Production proves that the process operates easily,and the product has stable quality and low cost.
