Constrained rolling forming method for large thin-walled outer T-shaped annular members

Abstract

The invention relates to a constraint rolling forming method for a large thin-wall outer T-shaped annular component. The method comprises the following steps that S1, a large thin-wall outer T-shapedannular component constraint rolling forming device which comprises a driving disc, a constraint mold, a feeding roller and a demolding ejector rod is assembled; S2, rolling is started, the driving disc drives the constraint mold and a prefabricated ring blank to do circular motion around the axis of the constraint mold, and the feeding roller rotates around the axis of the constraint mold; S3, after the feeding roller stops the radial feeding movement, a feeding system drives the feeding roller to downwards feed in the axial direction under the combined action of the feeding roller and the constraint mold; and S4, after rolling forming is finished, the demolding ejector rod ejects the formed component. The constraint rolling method belongs to the continuous local plastic forming, the forming force is small, the energy consumption is low, the near-net forming of the large thin-wall outer T-shaped annular component can be realized, the material utilization rate is high, the efficiency is high, the pollution is less, and the requirements of green manufacturing are met.

Description

technical field [0001] The invention relates to the field of forming and manufacturing large-scale ring parts, and more specifically relates to a constrained rolling forming method of a large-scale thin-walled outer T-shaped ring member. Background technique [0002] Large thin-walled outer T-shaped ring components are widely used in aviation, aerospace, ships, weapons and equipment, wind power, petrochemical and other fields, and their manufacturing technology is at the forefront of international high-end equipment manufacturing technology research. The main characteristics of large thin-walled outer T-shaped ring members are large diameter, large axial height, small wall thickness, and complex cross-sectional shape. For such complex components, the main processing methods include machining and welding. The machining method is to process a large rectangular cross-section ring through turning or milling to produce an outer T-shaped ring member. The utilization rate of mach...
