Detailed description of the invention
The utility model provides a kind of production line of neodymium iron boron, and the properties of product that it can further improve sintered NdFeB, have reduced scrapping of product.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the production line of the neodymium iron boron that the utility model embodiment provides, comprise weighing case, press and put hopper, it also comprises respectively weighing case, press and puts hopper sealed envelope, so that weighing case, press and put hopper and air insulated, and allow weighing case seal closure 1, the press seal closure 2 that neodymium iron boron powder enters and put hopper seal closure 3, press seal closure 2 is with weighing case seal closure 1 and put hopper seal closure 3 and be all communicated with.
In the production line of the neodymium iron boron that the present embodiment provides, be provided with respectively the weighing case seal closure 1 of parcel weighing case, the press seal closure 2 of parcel press, and parcel put hopper put hopper seal closure 3 so that weighing case, press and put hopper all and air insulated.In the process of producing, neodymium iron boron powder is put in weighing case seal closure 1 (this puts into process and is avoided neodymium iron boron powder to contact with air and prevent that air from entering into weighing case seal closure 1), then make weighing case weigh to neodymium iron boron powder, then the neodymium iron boron powder that weight is met to technological requirement is sent in press seal closure 2, press is pressed to neodymium iron boron powder, finally the blank after compressing is sent to put and in hopper, carries out vacuum packaging.
In the production line of the neodymium iron boron that the present embodiment provides, owing to above-mentionedly weighing, transfer, compressing, secondary transferring and vacuum-packed whole process, all carrying out with weighing case seal closure 1, the press seal closure 2 of air insulated with in putting hopper seal closure 3, so avoided neodymium iron boron powder to contact with air with blank in whole process, thereby avoid neodymium iron boron powder and blank oxidized, and then further improved the properties of product of sintered NdFeB, reduce product rejection.
In order further to optimize technique scheme, in the production line of the neodymium iron boron that the present embodiment provides, weighing case, press and put hopper laminating and arrange, and weighing case seal closure 1, press seal closure 2 and put hopper seal closure 3 and be structure as a whole.As depicted in figs. 1 and 2, on traditional production line, between weighing case and press, there is certain distance, so the neodymium iron boron powder cost regular hour that weighs up weight need to be transferred them in press, and because this transfer process is without the fence operation of isolated air, so caused the oxidation of neodymium iron boron powder.And in the present embodiment, by weighing case, press with put hopper laminating setting, can greatly shorten transfer distance, and make transfer operation more convenient, improve production efficiency.And, weighing case seal closure 1, press seal closure 2 be set and put hopper seal closure 3 and also avoided contacting of neodymium iron boron powder and air, prevent oxidation.By weighing case seal closure 1, press seal closure 2 with put hopper seal closure 3 and be set to integral structure, be preferred embodiment, it can farthest improve connection sealing each other.Certainly, can play under the prerequisite of air-isolation effect, also can and put hopper seal closure 3 by weighing case seal closure 1, press seal closure 2 and be set to split-type structural, the part of its connection is used rubber weather strip riveted joint to ensure sealing.
Preferably, weighing case seal closure 1, press seal closure 2 and put hopper seal closure 3 interior to be all filled with protective gas oxidized to prevent that Nd-Fe-B powder end from contacting with air.At weighing case seal closure 1, press seal closure 2 with put on the basis of hopper seal closure 3 air-isolations, be filled with therein protective gas, can further avoid neodymium iron boron powder to contact with air, further ensure properties of product.This protective gas can be mobile inert gas or nitrogen.
Concrete, press seal closure 2 all offers two glove ports 4 with putting on hopper seal closure 3, on each glove port 4, is all sealedly connected with the gloves that can allow staff to stretch into.As shown in Figure 1, in concrete production process, operating personnel can be extend into hand press seal closure 2 and be put in hopper seal closure 3 by glove port 4, and across gloves to operations such as neodymium iron boron powder and blank move into, enter mould, the demoulding, encapsulate and send.Wherein, neodymium iron boron powder is transferred to the operation of press seal closure 2 from weighing case seal closure 1, be transferred to the operation of putting hopper seal closure 3 with blank from press seal closure 2, and packaged blank sent to the operation of putting hopper seal closure 3, all can substitute manually and complete by conveyer.
Further, press seal closure 2 all seals and is provided with visual windows 5 with putting on hopper seal closure 3.By this visual windows 5, the progress of work that operating personnel can better observe press seal closure 2 and put the interior neodymium iron boron powder of hopper seal closure 3 or blank, better to control it.
In the present embodiment, press seal closure 2 is respectively by two openings (not shown in FIG.) and weighing case seal closure 1 with put hopper seal closure 3 and realize and being communicated with.
The specific works process of the neodymium iron boron production line that the present embodiment provides is:
Neodymium iron boron powder is after charging basket 6 is put into weighing case seal closure 1, the parameter that in weighing case, automatic powder measuring machine is set according to digital display controller 7 is delivered to quantitative neodymium iron boron powder in one powder box 8, the operating personnel that stand in like this on pedal 9 pass through the glove port 4 on press seal closure 2, the powder box 8 of neodymium iron boron powder will be filled, in the weighing case seal closure 1 connecting with press seal closure 2, be transferred in press seal closure 2, then the neodymium iron boron powder in powder box 8 is poured in the mold cavity of press and carried out die mould, afterwards the blank of moulding is transferred to and putting in hopper seal closure 3 that press seal closure 2 connects, and blank is used vacuum packaging machine 10 vacuumize packaging putting in hopper.The charging basket 6 that neodymium iron boron powder is wherein housed has gas shield; to prevent that air from causing and being oxidized and avoiding air to enter into weighing case seal closure 1 the neodymium iron boron powder in charging basket 6; press seal closure 2, weighing case seal closure 1 and put hopper seal closure 3 three in one and weighing case, press and put the enclosed environment that one of hopper composition is complete; and there is gas shield, thereby make in whole process neodymium iron boron powder or blank all under the protection in gas.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
