Abstract (en)
[origin: KR20150026890A] The present invention relates to a tool and a method for producing a disk comprising: at least one stamped or bored blanking stage (9) for cutting stamped parts, in particular, outer and inner contours (2, 4) of a disk blank (13); at least one waveform corrugating which is divided into an upper die part (17) and a lower die part (18) to compress burr (15) generated while the disk blank (13) is divided and cut; and an upper part (7) and a lower part (8) forming an embossing stage (10). The present invention is to provide tool and a method for producing the waveform disk, capable of reducing costs and improving the accuracy of the sharp edge, a shape, and a size of an external sawtooth of the waveform disks.
