Synchronous rotation pressure-bearing type forming mold structure of magnetic field forming press

Abstract

The invention discloses a synchronous rotation pressure-bearing type forming mold structure of a magnetic field forming press. A forming device comprises guide columns, a middle guide plate, a formingmold, a mold frame, an upper punch, a lower punch and a magnetic field coil; a core rod is arranged in the forming mold, the upper punch and the lower punch are located at the upper end and the lowerend of the forming mold respectively, and the magnetic field coil is located beside the forming mold; the upper punch comprises an upper cylinder, a top plate, an upper guide plate and an upper mold;and the lower punch comprises a lower cylinder, a lower guide plate, a lower mold continuous base and a lower mold fixing base. According to the synchronous rotation pressure-bearing type forming mold structure, a rotating mechanism is further arranged on the bottom plate, and the rotating mechanism is additionally arranged, so that when the neodymium iron boron powder is added into the forming mold, the lower mold, the forming mold and the core rod can rotate, the density distribution of the neodymium-iron-boron powder in the mold cavity of the forming mold is uniform, and a product is not prone to generating defects when being formed and pressed.

Description

technical field [0001] The invention relates to the technical field of metallurgical powder forming presses, in particular to a synchronous rotating pressure-bearing forming die structure of a 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 powder filling device of the existing magnetic field forming press has a uniform density distribution of the powder filled into the forming mold. If the density distribution of the powder filled into the cavity of the forming mold is not uniform, the product is prone to def...
