Title:
ELECTROMAGNETIC SHAPE CORRECTION DEVICE AND SHAPE CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/048198
Kind Code:
A1
Abstract:
An electromagnetic shape correction device, comprising a uniform pressure driving coil (1), a magnetic field shaper (2), a conductive channel (3) and a mold (6). The uniform pressure driving coil is arranged inside the conductive channel; the conductive channel and a workpiece (5) to be subjected to shape correction form a conductive loop; the magnetic field shaper is arranged between the uniform pressure driving coil and said workpiece; the uniform pressure driving coil generates a pulse magnetic field around the uniform pressure driving coil by means of pulse current discharge, and the pulse magnetic field generates an induced eddy current on the surface of the magnetic field shaper; the magnetic field shaper cooperates with the uniform pressure driving coil to generate an induction current in the conductive loop, and the induction current generates a pulse electromagnetic force on an area to be formed of said workpiece; and the area to be formed of said workpiece deforms into the mold under the action of the pulse electromagnetic force. Further provided is a shape correction method of the electromagnetic shape correction device. The shape correction device and the shape correction method can flexibly and accurately regulate and control the shape correction or multiple forming processes of a workpiece by means of the optimal design of the magnetic field shaper, and can effectively reduce the design difficulty and the manufacturing cost of a forming device.
