装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cleaning device, and in particular, in the press working of electromagnetic steel sheets used as iron cores of electric equipment such as self-sufficient iron cores of rotating electrical machines, the present invention relates to a cleaning device. The present invention relates to a leaning device suitable for removing iron powder particles adhering to the surface of pre-processed products after deburring with a deburring device.
近年、回転電機の大容量化に伴ないその固定子や回転子

物の付着がなく完全に絶縁物のみで保護された高品質な
鉄心が要求される。In recent years, as the capacity of rotating electric machines has increased, there has been a demand for larger diameter and multi-layer iron cores for stators and rotors. Particularly in large rotating electrical machines such as water turbine generators and turbine generators, a high-quality stator core is required that is completely protected only by insulators and has no foreign matter such as metal powder attached to the stator core.

のバリ３が発生する。By the way, this type of iron core usually uses a punched plate 1 obtained by pressing an electromagnetic steel sheet as shown in FIG. As shown in the figure, 0.03 to 0.05++ on by press processing
3 burrs are generated.

間にビリーローラ５で転圧しなから抜板１全通して前記
パリ３を除去する方法を採っている。For this reason, conventionally, as shown in Figs. 3 and 4, a belt 4 made of Endorenu's Cronuvertonia aluminum abrasive grains + 150% phenolic resin was bonded to the belt 4, and a billet for rolling pressure installed opposite to this belt 4 was used. A method is adopted in which the rollers 5 are used, and the blank 1 is completely passed through after being rolled by a billy roller 5 between these rollers to remove the paris 3.
ところがこの方法では、第５図に示すようにベルト４で
除去したパリ３が鉄粉６として抜板１の表面に付着し、

粉６が付着する。またこの加工面２には、パリ除去後も
数ミクロンのいわゆる二次パリが残ることがある。However, in this method, as shown in FIG.
In particular, the machined surface 2 around the periphery of the punched plate 1 has a rough surface, so many iron powders 6 adhere to it. In addition, so-called secondary particles of several microns may remain on the machined surface 2 even after removing the particles.
ところで、このバリ取９後の抜板１は、その表面に４な

低下させ鉄心の振動あるいは緩みの原因ともなる。By the way, the punched board 1 after deburring 9 is coated with insulating varnish to a thickness of 4 to 7.5 μm on its surface, and then the thickness is increased. If secondary particles remain, there is a risk that the interlayer insulation of the iron core will be destroyed and an interlayer short circuit will occur, and the space factor of the iron core will be lowered, causing vibration or loosening of the iron core.

かれるようになっている。FIG. 6 shows an example of an insulating varnish coating and drying device incorporating a cleaning device according to the present invention. In the figure, numeral 11 denotes a layered stack of shavings 1 after deburring and supplying them one by one to the cleaning device 12. This is an iron core insertion device. The punched board 1 supplied from the iron core insertion device 11 to the cleaning device 12 is sent to the varnish coating device 13 after foreign substances such as iron powder powder or secondary powder are completely removed. A varnish with a thickness of 4 to 7.5 microns is applied to the surface, and then the varnish is dried in a drying device 14, cooled in a cooling device 15, and then introduced into a core laminating device 16.
