Abstract
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
The present invention relates to a kind of apparatus and method of removing the burr behind the molded neodymium iron boron product.
Background technology
The problem that exists behind the existing molded neodymium iron boron product is: behind molded neodymium iron boron product, because of the influence of weak magnetic, can on the corner of product, form burr shape magnetic bundle, this can bring pollution when heat treatment, and on the product that forms by a firing spine is arranged, will bring many influences to later process.
Chinese patent application No.200410026317.9 (denomination of invention is " polishing, deburring and a cleaning equipment "); Chinese patent application No.03107373.5 (denomination of invention is " microballon goes grid burr method "); Chinese patent application No.02134307.1 (denomination of invention is " method and the equipment thereof of polishing of metal works vibro-grinding and deburring "), all disclose the method for certain deburring, but do not handled these burr shape magnetic bundles that exist behind the molded neodymium iron boron product.
Summary of the invention
The purpose of this invention is to provide a kind of apparatus and method of removing the burr behind the molded neodymium iron boron product, it can effectively remove the burr behind the molding neodymium iron boron, thereby helps heat-treatment furnace and later process.
For this reason, according to an aspect of the present invention, provide a kind of device of removing the burr behind the molded neodymium iron boron product, it is characterized in that: comprise demagnetizer, and this demagnetizer comprises demagnetization passage and nitrogen blowing and dust collection; Nitrogen blowing and dust collection are arranged on nearby and with this demagnetizer being interconnected of this demagnetizer; Demagnetization passage and nitrogen blowing and dust collection all are installed in the nitrogen protection case; The demagnetization passage comprises the outlet with the product of the inlet of the pressed compact that is communicated with of an end of demagnetization passage and the deburring that is communicated with an other end of the passage that demagnetizes.
According to another aspect of the present invention, a kind of method of removing the burr behind the molded neodymium iron boron product is provided, has it is characterized in that: pressed compact has been sent in the demagnetization passage, and touched the ferric induction switch, make the adhesive of ferric induction switch, thereby the alternating magnetic field source begins to produce alternating magnetic field; At this moment, nitrogen blowing switch adhesive, the blowing of beginning nitrogen and absorption powder.
The invention has the beneficial effects as follows: can remove the burr behind the molded neodymium iron boron product effectively; beneficial to sintering furnace: owing to removed residual burr; when the sintered NdFeB product, reduced a large amount of dust; therefore reduced the pollution of heating furnace inner bag; improved the efficient that adds heat conduction; protected the cleaning of vacuum system; improved the efficient that vacuumizes of vacuum system; also prolonged simultaneously the useful life of oil in the equipment; in addition; it is also very helpful that the cooling heat exchanger upper surface is kept clean, thereby improved heat exchanger effectiveness, energy efficient.In addition, also beneficial to later process: because burr can increase the roughness of product surface, make mill prolong process time, when roughness was too big, the precision of mill processing was difficult to guarantee; On the contrary, if removed burr, these problems have not just existed so.
Description of drawings
Fig. 1 is the schematic diagram according to demagnetizer of the present invention;
Fig. 2 is the flow chart according to demagnetization technology of the present invention.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.As illustrated in fig. 1 and 2, the present invention adopts the nitrogen air blow off with the demagnetization passage 21 of pressed compact 10 approach burr removers, just can effectively these burr shape magnetics be removed.
As shown in Figure 1, demagnetizer comprises demagnetization passage 21, nitrogen blowing and dust collection 22 be arranged on this demagnetizer 21 near, demagnetization passage 21 and nitrogen blowing and dust collection 22 all are installed in the nitrogen protection case 20.Pressed compact 10 is admitted to demagnetization passage 21 and demagnetizes, and waiting demagnetization to finish outlet from demagnetization passage 21 when coming out, and the burr powder has just been cleaned out, and has obtained the product 30 of deburring.
As shown in Figure 2, in the time of in pressed compact is admitted to the demagnetization passage, in step 201, this pressed compact touches ferric induction switch J1, makes ferric induction switch J1 adhesive; Alternating magnetic field source J2 just begins to produce alternating magnetic field in step 202; At this moment, in step 203, nitrogen blowing switch J3 adhesive, the blowing of beginning nitrogen and absorption powder.After deburring finished, ferromagnetic switch J1 disconnected, and alternating magnetic field source J2 and nitrogen blowing switch J3 also quit work.
The nitrogen blowing is blown into dust in the nitrogen blowing dust collection 22.
Burr remover is an AC demagnetization machine, and the magnetic field of the magnet surface of decorporating makes dust not be subjected to magnetic force and leaves; Nitrogen blowing dust collection 22 is containers, is used to adorn the dust of being blown down.
Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.In addition, should be understood that those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, but these equivalent form of values fall within the application's appended claims institute restricted portion equally.
