This article on the basis of a reasonable analysis of caliper stamping process, determine the forming of clamp needed to complete the final two die of parts. First design of the die to die, to complete the volume required to round rectangle of blank, from the product parts diagram to see the final forming part of the structure is simple and is a symmetric graph, blanking sections only need to ensure the blank dimension; second series of die design of bending and rolling die, to complete the final shaping, to ensure the clearance of 1 mm. Above the process die of design in meet processing precision of Foundation Shang full consider savings cost factors, determine has card hoop stamping parts most optimization of rushed Conference processing process; immediately by familiar various die of processing features and the internal structure, completed die overall structure of analysis; then for stock size, and row sample, and process size, and stamping pressure, and stamping Center, and die work part size, technology calculation, this Foundation Shang determine die of shape, last completed has Assembly figure and non-standard of parts figure and determine pressure machine type and the main parameter.
