Forging die for simple die forging of movable vane of fan and innovative machining method of movable vane

Abstract

The invention relates to an innovative machining method of a movable vane of a fan. The innovative machining method is characterized by comprising the following specific steps of S1, machining of a pre-forging piece; S2, forming of a vane blank piece; S3, drilling of the vane blank piece; S4, rough milling of a vane blank; and S5, finishing milling of the vane blank. The invention relates to a forging die for simple die forging special for machining of the movable vane of the fan. The forging die is characterized by comprising a forging die body, wherein the upper end surface of the forging die body and the horizontal direction form an inclined surface with an inclination angle of 7 degrees; the forging die body is internally provided with a pre-forging piece groove, and the two sides of the groove in the forging die body extend to the outside to form oil grooves. According to the innovative machining method and the forging die, a blank is formed by using the pre-forging piece, the pre-forging piece uses less material, and the pre-forging piece realizes forming of the pre-forging piece to the blank through the special forging die, so that the using amount of high chromium alloy canbe greatly reduced, the problems of consuming a large amount of alloy cutter heads and occupying a large amount of machine tool working hours are solved, and the fast, time-saving and material-savingmachining method of the fan vane is realized.

Description

Technical field [0001] The invention relates to the field of wind rotor blades, in particular to a forging die for simple die forging of wind rotor blades and an innovative processing method for the rotor blades. Background technique [0002] The blast furnace gas residual pressure power generation axial fan is an energy-saving device that converts the residual pressure of the gas into electric energy. There are many models, and the blades of each unit are different. The number of blades of each type is limited and the period of general ordering of blades is very short. It is too late to manufacture die forging molds. Forging blanks, so in the past, billets were forged into billets and milled into blades, which resulted in a lot of waste of materials. A blade billet needs about 43kg to 46kg, and such a large billet needs to be milled into 8kg blades. Milling more than 30 kilograms of special material high chromium alloy steel into iron filings requires a large amount of alloy cut...
