摘要： The present invention relates to molds and mold portions that comprise or have integrated therewith a resinous material and comprise at least one electromagnetic actuator imbedded in the resinous material, so as to be capable of further forming the at least one precursor area of the work piece. The resin is used to locate the coil, and clamps or other restraints preferably are used to keep the weaker electrically insulating resin out of a state of large tensile stress or strain, which may cause it to fracture. Preferably, the resinous material comprises metallic flakes imbedded therein.

摘要： A process, system, and improvement for a process for electromagnetic forming of a workpiece in which characteristics of the workpiece such as its geometry, electrical conductivity, quality, and magnetic permeability can be determined by monitoring the current and voltage in the workcoil. In an electromagnet forming process in which a power supply provides current to a workcoil and the electromagnetic field produced by the workcoil acts to form the workpiece, the dynamic interaction of the electromagnetic fields produced by the workcoil with the geometry, electrical conductivity, and magnetic permeability of the workpiece, provides information pertinent to the physical condition of the workpiece that is available for determination of quality and process control. This information can be obtained by deriving in real time the first several time derivatives of the current and voltage in the workcoil. In addition, the process can be extended by injecting test signals into the workcoil during the electromagnetic forming and monitoring the response to the test signals in the workcoil.

摘要： A method of using an electromagnetic forming machine to hem a panel assembly includes providing an inner panel and an outer panel. The outer panel has a plurality of flanges and a plurality of relief areas. An electric forming machine is provided having a coil for discharging electric energy to generate a magnetic field. The inner panel is positioned such that portions of the outer edge of the inner panel are aligned with the flanges of the outer panel to form a loose assembly of panels. The loose assembly of panels is positioned proximate the electromagnetic forming machine such that the coil surrounds the flanges and is disposed substantially coplanar with a plane formed by the relief areas. The electromagnetic forming machine is activated to generate a magnetic field causing the flanges to bend over.

摘要： A metal mold for electromagnetic forming, with the inner peripheral face thereof, serving as a forming face, is disposed on the outer peripheral side of a columnar workpiece, and a coil for electromagnetic forming is disposed on the inner peripheral side of the columnar workpiece. In a state of a configuration as described, electric energy is thrown into the coil for the electromagnetic forming, and the columnar workpiece is caused to undergo flaring to be thereby pressed against the forming face of the metal mold for the electromagnetic forming, so as to be turned into a shape corresponding to the forming face by means of the electromagnetic forming, thus obtaining a wheel rim. A disc is welded to the wheel rim obtained, and curling is applied to outer edges of the wheel rim. With the adoption of a method of manufacturing an automotive wheel, a manufacturing process as a whole is enhanced in efficiency.
