Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings and embodiments.

[0030] A precise powder feeding and feeding system for rare earth permanent magnet powder. Because the rare earth permanent magnet powder is easy to be oxidized, excessive oxygen content will seriously affect the performance of the prepared magnet. Therefore, in the best embodiment, the magnetic field orientation molding device and the system need to be placed in an inert gas atmosphere. If it is exposed to the atmosphere to operate, it is necessary to add antioxidants to the magnetic powder before the pressing process to prevent excessive oxidation of the magnetic powder.

[0031] Such as figure 1 As shown, the weighed magnetic powder is added to the weighing shovel 1-2, and the tapered hopper 2-1 is located below the discharge end of the weighing shovel 1-2, so that the magnetic powder can be poured into the weighing shovel 1-2. The top opening of the cone hopper 2-1....

Abstract

The invention provides a precise powder supply and powder feeding system for rare earth permanent magnet powder, which belongs to the technical field of NdFeB rare earth permanent magnet forming equipment. The system includes a weighing shovel, a tapered hopper, an organic hose, a powder filling box, a horizontal guide rail, a powder filling box push and pull device, and an electrical control system. The structure of the system is simple and reasonable, and the degree of automation is high. When the system is used for orientation forming, it can ensure the accurate weighing and filling of the magnetic powder required for the blank of the magnetic block, which reduces the labor intensity of the workers and has good practicability.

Description

Technical field [0001] The invention provides a precise powder supply and powder feeding system for rare earth permanent magnet powder, belonging to the technical field of neodymium iron boron rare earth permanent magnet forming equipment. Background technique [0002] Magnetic field orientation molding is an important production link in the sintered NdFeB industry. At present, most industrial production uses manual feeding after automatic weighing. The manual feeding efficiency is low, the operation proficiency of the workers is very high, and the operation process is dangerous. The realization of precise magnetic powder feeding and automatic feeding will greatly improve the automation degree and production efficiency of the molding process. Summary of the invention [0003] The purpose of the present invention is to improve the current problems of low efficiency and poor accuracy of manual feeding, and proposes a rare earth permanent magnetic powder precise powder feeding and f...
