Magnetic collector for magnetic pulse forming

Abstract

The invention discloses a magnetic collector for magnetic pulse forming, and relates to a magnetic collector. The invention aims at solving the problem that the structural strength of a magnetic collector, the insulation capacity of the gap of a longitudinal joint of the magnetic collector, and the insulation capacity between a working area of the magnetic collector and the machined workpiece are reduced due to a rapid temperature rise generated during a continuous magnetic pulse forming process, so that short circuit and structural damages among the longitudinal joint of the magnetic collector, the magnetic collector and the workpiece are caused, and finally the formation production chain is broken. According to the invention, at least one cooling channel ring is machined on a longitudinal arm; each cooling channel ring comprises a plurality of cooling channels; each cooling channel penetrates through an inner sleeve body in the longitudinal length direction and is internally charged with a refrigeration gas or a refrigeration liquid; and every two cooling channels are communicated through an external tube so as to form a serial cooling pipeline or a parallel cooling pipeline; and the Joule heat generated by the magnetic collector during multiple charge-discharge processes is brought away by charging the refrigeration gas or the refrigeration liquid in the cooling channel rings, thus effectively assisting to cool the magnetic collector. The magnetic collector disclosed by the invention is used in a magnetic pulse forming process.

AI Technical Summary

Benefits of technology

This patented technology improves on existing methods such as magnets or coils while still maintain their effectiveness at higher frequencies (upwards). It uses an external channel filled with special materials called crystals made from cerium oxide) which helps reduce friction when they are moved through them under strong pressure. By doing this, it prevents damage caused by thermal expansion and allows longer use without losing its function over time. Additionally, there're also included features like spiral grooves inside the pipings themselves to further enhance the efficiency of the device. Overall, these technical improvements improve the durability and reliability of current devices.

Problems solved by technology

This patented describes a type of magneque pulser (MPS), commonly called MPS). It involves creating tiny structures made up of thin sheets of material onto another piece of material undergoing fabricating operations like injection molds. These structures help shape complex metallic shapes without being damaged during these steps. However, current methods require long hours before each step results in poor product quality due to thermal stress issues associated with the use of strong permanent magnetism. To address this issue, some proposed solutions involve utilizing specialized tools and techniques to quickly respond to changes in the environment while maintaining good performance and controllability over large scale industrial applications.
