Forming device of full-automatic radiation ring floating type magnetic field forming press

Abstract

The invention discloses a forming device of a full-automatic radiation ring floating type magnetic field forming press. The forming device comprises a forming device body which comprises a guide column, a middle guide plate, forming molds, a mold frame, an upper punch, a lower punch and a magnetic field coil, wherein the middle guide plate is arranged on the guide column, and the mold frame is rotationally arranged on the middle guide plate; the forming molds are installed on the mold frame, a core rod is arranged in the forming molds, and the core rod is installed on the mold frame; the upperpunch and the lower punch are located at the upper ends and the lower ends of the forming molds respectively, and the magnetic field coil is located beside the forming molds; the upper punch comprises an upper cylinder, a top plate, an upper guide plate and an upper mold; the lower punch comprises a lower cylinder, a bottom plate, a lower guide plate, a lower mold connecting base and a lower moldfixing base. By improving the structure of the forming device, neodymium iron boron powder is subjected to compression molding, and the forming molds can move relative to each other, so that densitydistribution of the neodymium iron boron powder in mold cavities of the forming molds is uniform, the pressing effect is good, and the rejection rate is low.

Description

technical field [0001] The invention relates to the technical field of metallurgical powder forming presses, in particular to a forming device of 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. [0003] The forming mold of the existing magnetic field forming press is fixed. When the NdFeB powder in the forming mold is pressed, the density distribution of the NdFeB powder is very likely to be uneven, and the product is very likely to produce defects or waste products during forming ...

Problems solved by technology

[0003] The molding die of the existing magnetic field forming press is fixed. When the NdFeB powder in the molding die is pressed, the density distribution of the NdFeB powder is very likely to be uneven, and the product is very prone to defects or waste products during molding and pressing.
