Embodiment Construction

[0014] After the power supply E and the high-voltage capacitor C are connected in parallel, they are connected in series with the coil 4 and the circuit switch K; the metal plate 2 and the mold 3 with a clamp 31 are sequentially placed under the coil (the direction in which the coil generates electromagnetic force), and the metal plate is fixed by the clamp. top of the mold. After the high-voltage capacitor is fully charged by the power supply, when the loop switch is closed, the high-voltage capacitor discharges rapidly (microseconds) to the coil, and the coil flows a rapid current, thereby generating a changing magnetic field. With the continuous discharge of the high-voltage capacitor, the coil in the metal The direction of the plate generates a pulsed magnetic field. When the pulsed magnetic field passes through the metal plate, the metal plate generates an induced current, and the metal plate becomes a charged body. When the metal sheet is in a sharply changing magnet...

Abstract

The invention provides sheet metal electromagnetic forming equipment. The sheet metal electromagnetic forming equipment aims to solve the problem that a rolling technology is mainly used in a current sheet metal forming process, a rolling mill and a die are used, and sheet metal is rolled and formed at high temperature; the method belongs to contact type machining, mechanical scratches are formed on the surface of a sheet easily, and energy consumption is high. The sheet metal electromagnetic forming equipment is characterized in that a power supply is connected with a high-voltage capacitor in parallel, and is connected with a coil and a loop switch in series; the sheet metal and a die with a clamp are arranged below the coil in sequence, and the sheet metal is fixed to the upper surface of the die through the clamp. The sheet metal electromagnetic forming equipment has the advantages that electromagnetic force is power for workpiece forming, the equipment is not in direct contact with a workpiece in the workpiece forming process, and therefore the surface of the workpiece is free of the mechanical scratches, lubricating agents do not need to be added, and the surface quality of the workpiece is good.

Description

technical field [0001] The invention relates to a sheet metal forming equipment, in particular to an equipment for forming a sheet metal by using electromagnetic force. Background technique [0002] At present, the method of sheet metal forming mostly adopts the rolling process, that is, rolling forming, stamping forming, and hydraulic forming are carried out on the sheet metal by using a rolling mill and a mold at high temperature. This method belongs to contact processing and is easy to form mechanical friction on the surface of the sheet metal. marks and high energy consumption. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide an electromagnetic forming equipment for sheet metal using electromagnetic force. [0004] The purpose of the present invention is achieved in this way: after the power supply and the high-voltage capacitor are connected in parallel, they are connected in series w...
