Problems solved by technology
[0002] The problem existing after the molding of the existing NdFeB products is: after the molding of the NdFeB products, due to the influence of weak magnetism, burr-like magnetic powder beams will be formed on the corners of the products, which will cause pollution during heat treatment, Moreover, there are sharp thorns on the fired products, which will have a lot of influence on the subsequent process.
[0003] Chinese patent application No.200410026317.9 (invention name is "polishing, deburring and cleaning equipment"); Chinese patent application No.03107373.5 (invention name is "microbead deburring method"); The title is "Metal Workpiece Vibration Grinding and Polishing and Deburring Method and Equipment"), all disclose some deburring methods, but they do not deal with these burr-like magnetic powder beams that exist after the NdFeB product is formed.

Embodiment Construction
[0010] Below in conjunction with specific embodiment, further illustrate the present invention. Such as figure 1 and 2 As shown, in the present invention, the demagnetization passage 21 of the compact 10 through the deburring device, and the nitrogen blowing method can be used to effectively remove these burr-like magnetic powders.
[0011] Such as figure 1 As shown, the demagnetization device includes a demagnetization channel 21 , a nitrogen blower and a dust collector 22 are arranged near the demagnetization device 21 , and the demagnetization channel 21 and the nitrogen blower and dust collector 22 are installed in a nitrogen protection box 20 . The compact 10 is sent into the demagnetization passage 21 for demagnetization, and when the demagnetization is completed and exits the demagnetization passage 21, the burr powder is cleaned up, and the deburred product 30 is obtained.
[0012] Such as figure 2 As shown, when the green compact is sent into the demagnetization ...

A device and a method for removing the burr of a molded neodymium iron boron product are characterized by comprising a demagnetization device, and the demagnetization device comprises a demagnetization channel and a nitrogen air-blowing and dust collector; the nitrogen air-blowing and dust collector is arranged close to the demagnetization device and is communicated with the demagnetization device; the demagnetization channel and the nitrogen air-blowing and dust collector are both installed in a nitrogen protection box; and the demagnetization device comprises an inlet of a pressed compact which is communicated with one end of the demagnetization channel and an outlet of a product which is used for removing the burr and communicated with the other end of the demagnetization channel. The invention can effectively remove the burr of the molded neodymium iron boron product, thereby being conducive to the process effects of a heat treatment furnace and subsequent processes.
Description
technical field [0001] The invention relates to a device and a method for removing burrs after forming NdFeB products. Background technique [0002] The problem existing after the molding of the existing NdFeB products is: after the molding of the NdFeB products, due to the influence of weak magnetism, burr-like magnetic powder beams will be formed on the corners of the products, which will cause pollution during heat treatment, Moreover, there are spikes on the fired products, which will have a lot of influence on the subsequent processes. [0003] Chinese patent application No.200410026317.9 (invention name is "polishing, deburring and cleaning equipment"); Chinese patent application No.03107373.5 (invention name is "microbead deburring method"); Name is called " the method and equipment thereof of vibrating grinding and polishing of metal workpiece and deburring "), all discloses a certain method for deburring, but these burr-like magnetic powder beams that exist after t...
