What aspects of a stamped part are affected by the adjustment of the die clearance?

    Adjustment of the die clearance can have a significant impact on the stamped part in many ways, including but not limited to the following:

    Dimensional accuracy of stamped parts
        Too small a die clearance may cause the stamped part to be excessively squeezed during the stamping process, resulting in larger dimensions that are out of tolerance.
        Too large a die clearance may cause the stamped part to have a large rebound during stamping, resulting in small dimensions.
    Section quality of stamped parts
        A suitable die clearance can obtain a relatively flat, smooth and small burr stamping section.
        If the clearance is too small, the material will be subjected to too much tensile stress at the time of fracture, which will easily produce a tear-like rough section with large burrs.
        The gap is too large, the material is subjected to too little tensile stress at the time of fracture, and it is easy to form a wider collapse angle and a larger bright band.
    Mold life

        Reasonable mold clearance can make the mold in the work of uniform force, reduce wear and damage, thus extending the service life of the mold.
        Too small a gap will increase the friction between the mold and the material, resulting in rapid wear of the mold or even rupture.
        Too large a gap will increase the impact force on the mold, which will also shorten the life of the mold.
    Shape accuracy of stamped parts
        Uneven or inappropriate die clearance will lead to deformation of the stamped part during the stamping process, affecting its shape accuracy.
    Mechanical Properties of Stamped Parts
        Unsuitable die clearance may lead to residual stresses inside the stamped part, affecting its mechanical properties, such as strength and toughness.
