Abstract: Disclosed are an attractive electromagnetic flanging method using a stepped magnetic field shaper for a small metal pipe fitting, and a device. The problems that an existing electromagnetic flanging method uses a dual-coil and dual-power system, is complicated in control and coordination, and cumbersome in assembly configuration, and a forming effect of using a single coil system is poor are solved. The superior performance of a magnetic field in a specific area can be strengthened during flanging forming through the special stepped magnetic field shaper, such that an effect of replacing provision of an axial background magnetic field coil is achieved. The method solves the problem of insufficient radial electromagnetic force in the single coil system, and simplifies the problems of complicated control and coordination and cumbersome assembly configuration of the dual-coil system. Compared with the drive coil, the stepped magnetic field shaper is easy to manufacture and low in cost, thereby shortening the manufacturing period and facilitating actual batch production.

Abstract: An apparatus and method configured for manufacturing an aircraft part from formable material. The apparatus may include one or more rigid forming components onto which the formable material is placed and between which non-flange portions of the formable material may be compressed, and at least one inflatable component that, when expanded by inflation, presses flange portions of the formable material against at least one of the rigid forming components. The inflation component(s) may be arranged in any configuration for forming the formable material into C-shaped channels, single L-shaped channels, or opposing Z-shaped channels. Once pressed between the rigid forming components and/or the inflated inflatable components, the formable material may be heated for forming according to the particular formable material used.
