摘要： The method of producing an R—Fe—B magnet of the present invention is characterized in that R—Fe—B alloy fine powder is molded in a magnetic field and sintered using a lubricant for molding magnets containing specific components, individually or as a mixture, of specific amounts of methyl caproate and/or methyl caprylate, which provide high crystal orientation, and lubricant comprising depolymerized polymer for improving molded article strength, or a lubricant for molding magnets wherein Ti coupling agent that improves crystal orientation is added to this lubricant for molding magnets. Each particle of the fine powder has a high degree of crystal orientation in the direction of the magnetic field, and molded article strength is markedly improved, leading to improved mass-productivity and yield. Moreover, the above-mentioned lubricants do not react with this magnet powder during sintering and are emitted as a gas. Therefore, binder removal performance is excellent and as a result, an increase in the amount of C remaining in the sintered compact is inhibited, to obtain an R—Fe—B permanent magnet with high Br and iHc properties.
摘要翻译：本发明的R-Fe-B磁体的制造方法的特征在于，R-Fe-B合金细粉末在磁场中成型，并使用用于成型含有特定成分的磁体的润滑剂单独或作为混合物的特定量的提供高结晶取向的己酸甲酯和/或辛酸甲酯，以及包含用于提高成型体强度的解聚聚合物的润滑剂或用于成型磁体的润滑剂，其中将用于改善结晶取向的Ti偶联剂加入到该润滑剂中成型磁铁。细粉末的每个颗粒在磁场方向上具有高度的晶体取向，并且模制品强度显着提高，从而提高了批量生产率和产率。此外，上述润滑剂在烧结期间不与该磁粉反应，作为气体排出。因此，除去粘合剂的性能优异，因此抑制烧结体中剩余C量的增加，得到Br和iHc特性高的R-Fe-B永磁体。

摘要： Conveyance pitch is modified without modifying a pallet. A pallet conveying apparatus has: one, two or more pallets onto which a work can be loaded; a first and a second pallet rails on which the pallet can be movably loaded; first and second pallet feeding mechanisms that convey the pallet; and a pallet transfer mechanism that causes the pallet loaded on the first or second pallet rail to be transferred to the second or first pallet rail. The pallet transfer mechanism has a first movable portion that forms one part of the first pallet rail and that can be made continuous with the second pallet rail by being separated from another part; and a second movable portion that forms one part of the second pallet rail and that can be made continuous with the first pallet rail by being separated from another part. The first and second pallet feeding mechanisms have circulating endless first and second belts capable of engaging with the pallet that is loaded on each of the pallet rails.
