What should be paid attention to in the use of precision stamping dies? Dongguan Hardware will provide you with the answer that precision stamping often uses V-shaped gear ring pressing plate for strong edge pressing. The function of the V-shaped gear ring pressing plate is: 1. Prevent the material outside the shearing zone from flowing with the punch after shearing; 2. Clamp the material so that the material is always perpendicular to the punching direction without warping during the fine blanking process 3. Provide strong pressure, establish a three-way compressive stress state in the deformation zone, remove or prevent cracks caused by tensile stress, and prevent tearing of the cut surface. In order to ensure the shear quality of stamping parts, reduce power consumption and increase the service life of precision stamping dies, blank holder force must be correctly calculated and set. If the blank holder force is too small, the hydrostatic stress of the material in the deformation zone is low, which is not conducive to restraint Cracks produce tears on the shearing surface and affect the quality of the shearing surface. If the blank holder force is too large, excessive power consumption will be generated, the structure of the die will be complicated, and the service life of the precision stamping die will be reduced. Therefore, in the actual process, the blank holder force must be adjusted.
