A processing method of hyperboloid forming equipment

Abstract

The invention discloses a processing technology of double-curvature forming equipment, which includes: establishing a mechanical model of cold forming and studying the mechanical properties of special plates, deriving the rebound radius of material processing and forming; fitting the curved surface of double-curvature plates and performing Mathematical characterization: finite element numerical simulation to determine the springback of the shape of the double-curvature molding die: processing and manufacturing the curved plate die outer plate: the part of the outer plate whose curvature is not processed enough is thermally trimmed: install the special mold on the storage rack , assembled according to the number and partition of the base surface panel and fixed by spot welding; using the optical surface scanning measurement technology to reconstruct the shape of the hyperboloid after each bending: making a sample box for real-time measurement and control of the shape accuracy of the plate forming, the present invention Grasp the amount of springback compensation more accurately, ensure the quality of the product, better guarantee the accuracy of the curved surface, significantly improve the efficiency of bending and forming, reduce the manual workload, greatly shorten the working hours and save costs, and improve the quality of the product.

Description

technical field [0001] The invention relates to the shipbuilding industry, in particular to a processing method of cold-pressed hyperbolic panel forming equipment used for hull connection and transition. Background technique [0002] In terms of environmental protection, laws, and regulations, marine environmental protection is the starting point for platform dismantling. Dismantling old and idle platforms is of great significance for ensuring the marine environment, navigation and fishery production in the operating area. [0003] The structure of the semi-submersible lifting and dismantling platform is complex, which is different from the conventional semi-submersible platform. It is an asymmetric structure with different lower floating bodies and columns. There is no cross brace in the middle, and it is only connected by the upper hull, which makes the construction difficult. High precision is required. In order to avoid structural stress concentration, the connection be...
