Magnetic concentrator structure for magnetic pulse formation

Abstract

The invention discloses a magnetic concentrator structure for magnetic pulse formation, which relates to a device for forming and connecting a metal pipe by using a pulse magnetic field force. The included angle between the side end face and the axis of a conventional magnetic concentrator structure is between phi / 6 and phi / 2, so energy transfer efficiency and energy concentration efficiency of the magnetic field are low. The invention provides a novel magnetic concentrator, the longitudinal section structure of which is transverse H-shaped; the value of the oblique angle of the side end face of the magnetic concentrator structure depends on that the structure remarkably improves the magnetic field energy in a magnetic pulse formation discharge process so as to improve the energy conversion efficiency of the magnetic concentrator, further prolong the service lives of a coil and the magnetic concentrator, reduce the discharge voltage and the like.

Description

technical field The invention belongs to the magnetic pulse forming technology of metal pipe fittings, in particular to a device for forming and connecting metal pipe fittings by using pulsed magnetic field force. Background technique Magnetic pulse forming technology has the advantages of easy and precise control of processing energy, fast forming speed, high precision of formed workpiece, simple mold and strong versatility of equipment, and the whole forming process is pollution-free. It has been used in machinery, electronics, automobiles, aerospace and Weapons industry and many other fields. The basic principle of magnetic pulse shaping technology is the law of electromagnetic induction. A pulsed magnetic field passes through the workpiece and generates an induced current (also known as eddy current) on the workpiece. The magnetic field generated by the induced current interacts with the initial magnetic field to generate a huge pulsed magnetic pressure. When the magni...
