Description

Technical Field

[0001] The invention relates to the technical field of sintered NdFeB production and processing, in particular to a press blanking device for sintered NdFeB permanent magnet material. Background Art

[0002] Sintered NdFeB permanent magnets are manufactured using a powder metallurgy process. The smelted alloy is made into powder and pressed into a compact in a magnetic field. The compact is then sintered in an inert gas or vacuum to achieve densification. Aging heat treatment is usually required to increase the coercive force of the magnet. Sintered NdFeB permanent magnets have excellent magnetic properties and are widely used in electronics, electrical machinery, medical equipment, toys, packaging, hardware machinery, aerospace, and other fields. Common applications include permanent magnet motors, speakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment.

[0003] Usually before pressing the sintered NdFeB powder, it needs to be stirred and filtered to prevent the impurities contained in the sintered NdFeB powder from affecting subsequent use.

[0004] According to a press unloading device for sintered NdFeB permanent magnet materials disclosed in Chinese patent CN208460552U, impurities in the mixed raw materials can be filtered through the filter screen at the bottom of the material trough in the filter bin, thereby improving the product quality of the formed tablets. The inclined material trough allows the impurities filtered out of the filter bin to slide into the waste guide groove, and the inclined waste guide groove can be used to guide the filtered impurities into the waste bin for collection and cleaning. However, during the filtering of the raw materials, the raw materials are prone to clogging the filter holes, affecting the subsequent clogging of the raw materials and requiring manual cleaning, which reduces efficiency and increases labor.

[0005] In order to solve the above-mentioned problems, a press blanking device for sintered NdFeB permanent magnet material is proposed. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a press blanking device for sintered NdFeB permanent magnet material to solve the problem of production and processing of sintered NdFeB.

[0022] The beneficial effects of the present invention are as follows: the provided motor is operated, the connecting rod is rotated, and the rotating rod is connected to the stirring plate to rotate, thereby stirring the material.

[0023] The impurities inside the material are initially filtered through filter mesh one.

[0049] In this embodiment,

[0050] Example 3

[0051] On the basis of Example 1, the press blanking device for sintered NdFeB permanent magnet material provided by the present invention is as follows: Figures 1 to 5 As shown: the filter part 73 includes an inclined plate 731 fixedly mounted on the inner wall of the box body 1, and a threaded groove 732 is provided on the top of the inclined plate 731.
