A simple forging die for fan rotor blades and innovative processing method for rotor blades

Abstract

The invention relates to an innovative processing method for a fan rotor blade, which is characterized in that: the specific steps are as follows: S1: processing of pre-forged parts; S2: forming of blade blanks; S3: drilling of blade blanks; S4: roughing of blade blanks Milling; S5: fine milling of blade blanks; a simple forging die for fan blade processing, which is characterized in that it includes a main body of the forging die, and the upper end surface of the main body of the forging die forms an inclination with an inclination angle of 7° with the horizontal direction surface; the main body of the forging die is provided with a pre-forging groove, and the two sides of the groove in the main body of the forging die extend to the outside with oil grooves; in the present invention, the pre-forging is used to form a blank, and the pre-forging uses less material, and the pre-forging is passed through a special The advanced die forging tool realizes the forming from the pre-forging to the blank. This method can greatly reduce the use of high-chromium alloys, avoid the problem of consuming a large amount of alloy cutter heads and occupying a large amount of working hours of the machine tool, and realize the fast speed of the fan blades. , Time-saving and material-saving processing methods.

Description

technical field [0001] The invention relates to the field of fan blades, in particular to a forging die for simple die forging of fan blades and an innovative processing method for the blades. Background technique [0002] The blast furnace gas residual pressure power generation axial flow fan is an energy-saving equipment that converts the residual gas pressure into electric energy. There are many models, and the blades of each unit are different. The number of each type of blades is limited and the cycle of ordering blades is generally too short to make die forging dies. Forging blanks, so in the past, they were forged into billets and milled into blades, which resulted in a lot of waste of materials. A blade billet required about 43kg to 46kg, and such a large billet was milled into an 8kg blade. Milling more than 30 kilograms of special material high-chromium alloy steel into iron filings requires a lot of alloy cutter heads and takes up a lot of machine time. Therefore,...
