Abstract
In a cutting die having a cutting chip, applied to a punch press, and cutting a work in collaboration with a cutting punch, a resistance member for guiding swarf generated during cutting of the work through the cutting chip and dividing it by giving resistance to it is provided around a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged to an outside so as to prevent clogging by scrap.
Claims16
A cutting die having a cutting chip, applied to a punch press, and cutting a work in collaboration with a cutting punch, characterized in that
- a resistance member for guiding swarf generated during cutting of the work through the cutting chip and dividing it by giving resistance to it is provided around a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged to an outside so as to prevent clogging by scrap, and the resistance member is fixed to a side wall of the scrap discharge hole formed in a die body and penetrates through an ejector plate.

A cutting die having a cutting chip, applied to a punch press, and cutting a work in collaboration with a cutting punch, characterized in that
- a resistance member having an opening portion through which swarf generated during cutting of a work through the cutting chip passes and dividing the swarf by giving resistance to the swarf is provided around a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged to an outside so as to prevent clogging by swarf.
A cutting die having a cutting chip, applied to a punch press, and cutting a work in collaboration with a cutting punch, characterized in that
- a resistance member for guiding swarf generated during cutting of the work through the cutting chip and dividing it by giving resistance to it is provided on an upper part of a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged to an outside so as to prevent clogging by swarf, the resistance member has a cuboid shape in entirety, and in the resistance member, a division chamber is formed which communicates with the scrap discharge hole at an open portion side between the cutting chip and the resistance member and at a lower side of the resistance member and in which another side of the resistance member is surrounded by a wall.
