Technical Field
The utility model relates to a cutting jig for a stamping scrap-return-preventing wire.
Background
The rebound of the waste materials during the stamping process is a common phenomenon, which easily causes problems of product badness, die damage and the like, and particularly the rebound of the waste materials is easily caused by the blanking of thin plate small-aperture products and the trimming with less constraint force of female dies. In a general blanking gap, the size of the discharged scrap is smaller than the hole diameter of the die, and therefore scrap rebound is likely to occur. Vacuum adsorption at the edge of the male die, adsorption generated by oil, magnetic force of the male die and the like are main reasons for causing rebound of waste materials in the stamping process. However, air cannot be blown on the male die for too small holes, the waste suction device increases the cost, and the cleaning is troublesome.
