Abstract
Description
本発明は、金属加工油組成物、及び金属板積層体の製造方法に関する。 The present invention relates to a metalworking oil composition and a method for producing a metal sheet laminate.
モータ、発電機等の鉄心は、渦電流損を抑制するために表面に絶縁被膜を施した電磁鋼板を順次打ち抜き加工することにより製造されている。打ち抜き加工では、プレス機に設置された加工用の金型により、順次送り出される電磁鋼板の鉄心各部が打ち抜かれる。この打ち抜き加工後の複数の鉄心素片を積層一体化することで、積層鉄心が製造されてきた。 Iron cores such as motors and generators are manufactured by sequentially punching a magnetic steel sheet having an insulating coating on the surface in order to suppress eddy current loss. In the punching process, the respective iron core parts of the magnetic steel sheets sequentially fed out are punched out by a processing die installed in a press machine. A laminated iron core has been manufactured by laminating and integrating a plurality of iron core pieces after this punching process.
鉄心素片の積層は、金型の中でカシメを施して一体化させる積層かしめ法が広く採用されてきた。しかしながら、近年、電磁鋼板は、更に渦電流損を抑制するために、板厚を薄くする傾向にあり、カシメのための凹凸部を作製できず、積層かしめ法による積層が困難になっている。 A lamination caulking method has been widely adopted in which lamination of core pieces is performed by caulking in a mold so as to be integrated. However, in recent years, in order to further suppress eddy current loss, the electromagnetic steel sheet tends to be thinner, and asperities can not be produced for caulking, making lamination by the caulking method difficult.
上記の問題を回避するため、鉄心素片同士を接着剤によって貼付け積層する技術が検討されている。
特許文献1には、片面又は両面にプレス加工油を塗布したフープ材に複数のプレス加工を順次施し、当該フープ材の片面に接着剤を塗布した上で外形打ち抜き加工を行って金属薄板を得て、当該金属薄板を所定枚数積層接着することによって金属板積層体を製造する方法であって、前記プレス加工油に硬化促進剤が添加されたことを特徴とする金属板積層体の製造方法が開示されている。
In order to avoid the above-mentioned problems, a technique of laminating and laminating iron core pieces with an adhesive has been studied.
According to Patent Document 1, a hoop material having a pressing oil applied to one side or both sides is sequentially subjected to a plurality of pressing processes, an adhesive is applied to one side of the hoop material, and then an outline punching process is performed to obtain a metal sheet. A method of manufacturing a metal plate laminate by laminating and bonding a predetermined number of the metal thin plates, wherein a hardening accelerator is added to the pressed oil; It is disclosed.
特許文献1に開示の製造方法によると、プレス加工油に硬化促進剤を添加したため、プレス加工油を除去することなく金属薄板間の接着を実施でき、製造工程の簡略化等が可能になるものの、プレス加工の加工性と嫌気性接着剤の接着性との両立については更なる改善の余地がある。 According to the manufacturing method disclosed in Patent Document 1, since the hardening accelerator is added to the press processing oil, adhesion between the metal thin plates can be carried out without removing the press processing oil, and the manufacturing process can be simplified. There is still room for further improvement in the compatibility between the press processability and the adhesion of the anaerobic adhesive.
本発明は、上記問題点に鑑みてなされたものであって、電磁鋼板等の被加工材を加工する際に優れた加工性を付与することができ、かつ嫌気性接着剤によって被加工材同士を接着する際に除去しなくても良好な接着性が得られる金属加工油組成物、及び該金属加工油組成物を用いた金属板積層体の製造方法を提供することを目的とする。 The present invention has been made in view of the above problems, and can impart excellent processability when processing a processed material such as a magnetic steel sheet, and the processed materials can be processed by an anaerobic adhesive.

In the evaluation results of Table 1, "-" indicates that it is not measured.
In Table 1, carbon number of R means carbon number of R in the said General formula (1).
表1の結果により、実施例1及び2の金属加工油組成物は、(B)金属石鹸を配合していない比較例5と同等の良好な打ち抜き加工性を保ちつつ、硬化促進剤の溶解性に優れ、接着剤の接着性にも優れていることが確認された。一方、硬化促進剤として、上記一般式(1)におけるRの炭素数が16を超える金属石鹸又はフタロシアニン銅(II)を使用した比較例1〜3は、硬化促進剤の溶解性に劣り、接着剤の接着性が低かった。また、Zn−DTPを使用した比較例4は、硬化促進剤の溶解性には優れていたものの、接着剤の接着性が低かった。また、溶剤として引火点が20℃未満であるアセトンを使用した比較例6では、溶剤の揮発性が高くなりすぎ、電磁鋼板の表面に硬化促進剤及び油性剤が明らかに偏在していることが目視にて確認され、それに伴い、打ち抜き加工性に劣っていた。また、(C)油性剤を配合していない比較例7は、打ち抜き加工性に劣っていた。 According to the results in Table 1, the metalworking oil compositions of Examples 1 and 2 have the solubility of the curing accelerator while maintaining good punching processability equivalent to that of Comparative Example 5 in which (B) metal soap is not blended. It was confirmed that the adhesive was excellent. On the other hand, Comparative Examples 1 to 3 in which metal soaps or phthalocyanine copper (II) having a carbon number of 16 or more in R in the above general formula (1) were used as curing accelerators were poor in solubility of curing accelerators and adhesion The adhesion of the agent was low. Moreover, although the comparative example 4 using Zn-DTP was excellent in the solubility of the hardening accelerator, the adhesiveness of the adhesive was low. Moreover, in Comparative Example 6 using acetone having a flash point of less than 20 ° C. as the solvent, the volatility of the solvent is too high, and the curing accelerator and the oil agent are clearly localized on the surface of the magnetic steel sheet. It confirmed visually and was inferior to punching processability in connection with it. Moreover, the comparative example 7 which is not mix | blending the (C) oil-based agent was inferior to the punching processability.
