Some practical cases of successful optimization of process parameters of silicon steel transformer lamination by high-speed presses

Case one:
    A transformer manufacturing enterprise found that the stamped silicon steel transformer laminations have more burrs and the dimensional accuracy is not enough. Through the following optimization measures have achieved good results:

    Reduce the stamping pressure: After re-evaluating and calculating the material properties of silicon steel, the stamping pressure is appropriately reduced, which reduces the excessive deformation of the material and thus reduces the generation of burrs.
    Adjustment of stamping speed: By gradually increasing the stamping speed and conducting tests, an optimal speed that guarantees both production efficiency and laminated sheet quality was finally determined.
    Optimize die clearance: After several measurements and tests, the die clearance was fine-tuned to a more appropriate value, which significantly improved the dimensional accuracy and edge quality of the laminated sheets.

Case two:
   Another company was facing problems of rapid mold wear and micro-cracks on the surface of the stacked sheets during production. They took the following optimization steps:
    Improved the lubrication and cooling system: A more efficient lubricant was selected, and the spray angle and flow rate of the coolant were optimized to effectively lower the die temperature and reduce die wear.
    Optimize the nesting scheme: redesigned the nesting method to improve the stress distribution during the stamping process while increasing the material utilization rate, reducing the appearance of micro-cracks in the laminated pieces.
