Precision and guarantee measures required for precision stamping products 'hardware'

Precision stamping processing products required accuracy and guarantee measures: 1, the dimensional accuracy of the table rationality, economic and value research. 2. The accuracy of batch-produced parts is slightly lower than that of single-piece bending dies due to the use of progressive bending dies. The guide pin (guide plate) gap, which is directly related to the accuracy of the part, has a reference value as follows (when the part thickness is 0,35～2.0mm): Single-piece bending die: the difference between the guide pin (guide plate) and the part Gap 0.005~0.010mm Progressive Bending Die: Considering the avoidance and the wear of the guide plate, take 0.015~O. 025mm. 3. Is the bending radius of the part smaller than the small bending radius of the material? 4. Considering the structural shape of the part, is the bending process excessively shortened? Is the ratio of the height H value to the plate thickness too small? Normally, take H Add the bending radius to 2.5 times the plate thickness. When the height dimension cannot be kept constant due to the different thickness and hardness of the material, a post-bending resection process should be added to ensure the H value.
