Abstract

The invention relates to the technical field of wind power flange manufacturing, in particular to an assembling die and a flanging manufacturing process. The assembling die comprises a preforming die and a forming die, wherein the preforming die is used for performing radial preforming rolling on the inner wall of an annular flange blank by adopting a semi-closure hole pattern; the forming die is used for performing radial forming rolling on the inner wall of the annular flange blank by adopting the semi-closure hole pattern; the preforming die comprises a quick-changing barrel; an upper baffle, an upper pre-die, a pre-cutting knife, a lower pre-die and a lower baffle sleeve the quick-changing barrel from top to bottom in sequence; the forming die comprises the quick-changing barrel; the upper baffle, an upper main die, a main cutting knife, a lower main die and a lower baffle sleeve the quick-changing barrel from top to bottom in sequence. The assembling die and the flanging manufacturing process disclosed by the invention, dimensional accuracy of rolling and ring rolling is increased, the flatness of the end face of a product can be conveniently controlled, and is increased; the product material and cost are reduced, and manufacturing is time-saving and labor-saving; the energy consumption of the process is low, the production efficiency is high, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of wind power flange manufacturing, in particular to a combined mold and flange manufacturing process. Background technique [0002] The wind power flange is a large annular part. With the continuous increase of the capacity of the wind power generation unit, the diameter of the wind power tower continues to increase, and the wind power flange used in the wind power tower also increases accordingly. At present, the longitudinal section of the commonly used wind power flange is an L-shaped inner step cross section, and the formed product of the wind power flange has a large size and a large tonnage. [0003] At present, the traditional method of manufacturing wind power flange forming blanks is to roll and expand a single wind power flange blank with a rectangular longitudinal section through a ring rolling machine to be processed into a single wind power flange forming blank. In the traditional manufacturin...
