The control system enables current to flow in the magnetic spring 207, when the current flows through the magnetic spring 207, the magnetic spring 207 contracts under the action of a magnetic field, the control system controls the magnitude of the current which is led into the magnetic spring 207, the current is enabled to continuously change from small to large and then from large to small, the magnetic field generated by the magnetic spring 207 is enabled to continuously change from large to small, the number of magnetic induction lines around the magnetic spring 207 is enabled to continuously change from small to large and then from variable to small, the magnetic induction lines cut on the outer vortex plate 204 and the inner vortex plate 205 are enabled to continuously change from large to small and further enable the outer vortex plate 204 and the inner vortex plate 205 to generate heat under the action of an electric vortex, and the outer ring 201 and the inner ring 202 heat the raw materials through the heat generated by the outer vortex plate 204 and the inner vortex plate 205.
When the magnetic spring 207 is stretched under the action of the magnetic field, the carrier plate 206 is driven by the magnetic spring 207 to slide on the guide plate 208, the screw 210 rotates under the action of the threaded hole, the screw 210 drives the dial plate 213 to rotate in the heat conducting column 211, the gear teeth continuously stir the plectrum under the drive of the dial plate 213 to enable the plectrum to vibrate, the plectrum transmits the vibration to the heat conducting column 211 and the outer ring 201/inner ring 202, and the outer ring 201 and the inner ring 202 vibrate the raw material or the neodymium iron boron magnetic ring finished product.
After the raw materials are processed into the neodymium iron boron magnetic ring, the cooling system infuses cooling liquid into the outer ring 201 and the inner ring 202 through the pipeline, and the cooling liquid slowly cools the neodymium iron boron magnetic ring, and in this process, the current still passes through in the magnetic reed 207, and outer vortex plate 204 and inner vortex plate 205 continue to produce heat, heats the cooling liquid through the heat, prevents that the outer ring 201 and the inner ring 202 from cooling too fast and causing the neodymium iron boron magnetic ring quality to be impaired. When the cooling liquid is heated, the screw rod 210 rotates, the drive plate 213 drives the drive plate through the gear teeth, so that the outer ring 201 and the inner ring 202 vibrate, and the neodymium iron boron magnetic ring is subjected to stress relief and demolding through vibration, so that the neodymium iron boron magnetic ring is separated from the outer ring 201 and the inner ring 202.
The upper template 3 and the lower template 2 are separated under the driving of the lower pressure cylinder 302, the channel is opened by the valve mechanism, then the ejector 101 is extended under the control of the control system, the neodymium iron boron magnetic ring is ejected out of the forming cavity by the ejector rod 102, and the finished neodymium iron boron magnetic ring is conveyed to the blanking mechanism by the ejection mechanism 6.
