Radial Ring Magnetic Field Forming Press

Bidirectional high-precision forming, with bidirectional forming synchronization accuracy reaching ±0.005mm/s. Utilizes the company's self-developed servo electric cylinder technology and overall water-cooled coils with temperature detection and constant temperature control, being environmentally friendly, safe, and energy-saving. This press, through the magnetic circuit design of the frame and die, uses an opposed pressing method to generate a uniform radial magnetic field within the die cavity, used for pressing radially oriented rare earth permanent magnet material ring products.

Function Introduction

Parameter centralized management: Achieves full data control through a 10-inch touch screen for setting upper/lower cylinder limits/speeds, adjusting magnetizing/demagnetizing current, monitoring pressing pressure, setting forming dimensions, configuring weighing parameters, setting protection thresholds, and multi-period parameter settings.
Intelligent magnetizing/demagnetizing control: IGBT dual-loop system supports 0.5-1.5S ultra-fast forward/reverse switching, integrating five-level safety protection against overload/overvoltage/undervoltage/short circuit/coil leakage.
Oriented material forming: Specifically designed for multi-level oriented permanent magnet material pressing, supporting customized product production.
