Full-automatic floating type magnetic field forming press for radiation rings

Abstract

The invention discloses a full-automatic floating type magnetic field forming press for radiation rings. The full-automatic floating type magnetic field forming press comprises a framework. A bucket,a powder weighing device, a conveying device and a forming device are hermetically arranged on the framework, the bucket is positioned above the powder weighing device, the powder weighing device, theconveying device and the forming device are transversely sequentially arranged, the forming device comprises a forming die, an upper punch, a lower punch and a magnetic field coil, the upper punch and the lower punch are positioned at the upper end and the lower end of the forming die, the magnetic field coil is positioned beside the forming die, a balance system is arranged below the conveying device, a precision control box for controlling the balance system is arranged beside the balance system, and the forming die is connected with the conveying device. The full-automatic floating type magnetic field forming press has the advantages that neodymium, iron and boron powder in a cavity of the forming die is uniform in density distribution, defects of products can be prevented during forming pressing, excellent pressing effects can be realized, and the full-automatic floating type magnetic field forming press is low in rejection rate.

Description

technical field [0001] The invention relates to the technical field of metallurgical powder forming presses, in particular to a fully automatic radiation ring floating magnetic field forming press. Background technique [0002] The magnetic field molding press mainly includes a sealed frame, which is equipped with a powder weighing device, a feeding device and a molding device. The NdFeB powder first enters the powder weighing device through the barrel, and the powder weighing device weighs the quantitative NdFeB powder. Then put it into the feeding device, and finally push it to the molding device by the feeding device, and put the NdFeB powder into the molding mold, and then press the NdFeB powder. [0003] The powder weighing device is an important part of the NdFeB powder magnetic field forming press. The feeding process of the NdFeB forming press includes: the NdFeB powder first enters the weighing device through the barrel, and the weighing device weighs the quantitati...

Problems solved by technology

[0004] However, the density distribution of the powder filled into the forming mold by the existing powder feeding device for the magnetic field forming press is uneven. If the density distribution of the powder filled into the cavity of the forming mold is uneven, the product is prone to defects or waste product

[0005] In addition, the traditional press molding mold is fixed. When pressing the NdFeB powder in the molding mold, it is easy to cause the density distribution of the NdFeB powder to be uneven, and the product is prone to defects or waste products during molding and pressing. When pressing the magnetic radiation ring, the source of the magnetic field applies a radial magnetic field to the magnetic ring obtained during the forming process to obtain a formed radiation ring. However, since the relative position of the source of the magnetic field and the forming mold remains unchanged, the relative distance between the source of the magnetic field in the forming mold The radiation ring farther away has a smaller magnetism, and the radiation ring with a closer distance to the source of the magnetic field in the forming mold has a higher magnetism, resulting in uneven magnetic distribution of the radiation ring
