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.
Claims6
A cutting die applied to a punch press, the cutting die having a cutting chip, and the cutting die cutting a work in collaboration with a cutting punch, the cutting die comprising:
- a resistance member having an opening portion through which swarf generated during cutting of a work via the cutting chip passes, wherein the resistance member divides the swarf by imparting resistance to the swarf, the resistance member being provided proximate a scrap discharge hole so that the divided swarf does not remain in the scrap discharge hole but is discharged outside of the scrap discharge hole so as to prevent clogging of the scrap discharge hole by the divided swarf, and
- a rear surface of the opening portion being defined at an end of the opening portion that is rearward of a forward position defined at the location of the cutting chip,
- wherein a shape of the rear surface of the opening portion is tapered.
A cutting die applied to a punch press, the cutting die having a cutting chip, and the cutting die cutting a work in collaboration with a cutting punch, the cutting die comprising:
- a resistance member for guiding swarf generated during cutting of the work via the cutting chip, wherein an opening portion is formed in the resistance member at an open portion side of the resistance member, wherein the resistance member divides the swarf by imparting resistance to the swarf, the resistance member being 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 outside of the scrap discharge hole so as to prevent clogging of the scrap discharge hole by the divided swarf, the resistance member has an overall cuboid shape, wherein a division chamber is formed within the resistance member, the division chamber communicating with the scrap discharge hole at the open portion side of the resistance member, and wherein the division chamber communicates with the scrap discharge hole at a lower side of the resistance member, and
- a rear surface of the opening portion being defined at an end of the opening portion that is rearward of a forward position defined at the location of the cutting chip,
- wherein a shape of the rear surface of the opening portion is tapered.
