Material stacking and transferring system for sintered Nd-Fe-B formed blanks

Abstract

The invention discloses a material stacking and transferring system for sintered Nd-Fe-B formed blanks. The material stacking and transferring system comprises a controller, a feeding device, a material and pot stacking device, a pot storage device and a transferring trolley. The feeding device is used for conveying the sintered Nd-Fe-B formed blanks output by a forming press into the material andpot stacking device, the pot storage device is used for storing to-be-used sintering pots, and the material and pot stacking device is used for transferring the sintering pots in the pot storage device into the material and pot stacking device, then arranging the sintering pots in sequence, stacking the sintered Nd-Fe-B formed blanks into the sintering pots in sequence and conveying the sinteringpots in which the sintered Nd-Fe-B formed blanks are stacked into the feeding trolley, and the feeding trolley is used for receiving the sintering pots in which the sintered Nd-Fe-B formed blanks arestacked and conveying the sintering pots to the position of a sintering furnace. The material stacking and transferring system has the beneficial effects that the oxidization risks are small, the transferring efficiency is high, the labor intensity is low, the labor cost is low, meanwhile, the transferring damage rate can be reduced, material waste is avoided, and environment pollution is reduced.

Description

technical field [0001] The invention relates to a code material and a transfer system, in particular to a code material and a transfer system for sintered NdFeB forming blanks. Background technique [0002] The preparation process of sintered NdFeB magnets includes the forming and pressing process and the sintering process. The sintered NdFeB permanent magnet material is first pressed by a forming press to obtain a sintered NdFeB forming blank, and the sintered NdFeB forming blank is then sintered through a sintering furnace. A sintered NdFeB magnet is obtained. Since the rare earth elements contained in sintered NdFeB permanent magnet materials are easily oxidized, when the rare earth elements are oxidized, their permanent magnetic properties will be weakened or even invalidated. Therefore, nitrogen is usually used in the process of preparing sintered NdFeB magnets. Generate a protective atmosphere for protection. The forming and pressing process and the sintering process...

AI Technical Summary

Problems solved by technology

In the process of transferring the sintered NdFeB molding blank from the molding press to the sintering furnace, there are many transfer links, and each transfer equipment needs to replace the internal air with a large amount of nitrogen every time to ensure an oxygen-free environment inside. If the standard is met, the sintered NdFeB billet will be oxidized, and there is a great risk of oxidation; and the transfer process is mainly manual handling, the transfer efficiency is low, the labor intensity is high, and the labor cost is high. The handling process of the sintered NdFeB billet It is easy to bump and cause corner drop, and the transfer damage rate is high; and the use of plastic bags has caused a lot of environmental pollution and material waste
