Abstract

The special-shaped curved surface medium-thickness plate machining method based on multi-point flexible bending comprises the following steps that firstly, rhinoceros software Rhinoceros is adopted for conducting enveloping curved surface fitting modeling on a special-shaped curved surface medium-thickness plate through a plurality of preset gradual change point positions, the special-shaped curved surface medium-thickness plate is unfolded and lofted, and part blanking is completed; step 2, dividing the modeling special-shaped curved surface into longitude lines, latitude lines and a plurality of divided to-be-bent areas by virtue of rhinoceros software; thirdly, a special-shaped curved surface inspection jig frame is manufactured; fourthly, multi-point flexible bending is conducted in the divided longitude and latitude directions through oil pressure equipment; fifthly, the medium-thickness plate subjected to flexible bending forming is subjected to repeated curved surface inspection jig frame inspection; and 6, measuring the curved surface key control point by using high-precision measuring equipment, and completing the measurement when the measurement result reaches the set required precision. The problems that in the prior art, a medium-thickness plate special-shaped curved surface machining die is expensive, and the forming quality is poor are solved.

Description

technical field [0001] The invention relates to a processing and forming method for a medium-thick plate with a special-shaped curved surface, in particular to a processing method for a medium-thick plate with a special-shaped curved surface based on multi-point flexible bending. Background technique [0002] With the development of the times and the continuous progress of my country's modernization construction, batch after batch of large-scale and technically complex infrastructure, large-scale public works, super high-rise buildings, cultural and sports venues and other steel structure projects have been completed one after another. Improve the overall national strength and the material and cultural level of the people. At the same time, the technical level of architectural steel structures is also constantly improving, and the technical characteristics of its production and processing have gradually shifted from "high, heavy, large, and refined" required by the overall ap...
