Precision stamping parts stamping process, can appear sometimes wrinkled conditions causing workpiece scrapped.
The author to tell everyone! ! ! !
The cause of workpiece wrinkles is: lubricating oil or too much brushing 'frequent, lubricating oil to use, but can't use too much;
And furthermore, inappropriate position of coating.
Blank-holder force is insufficient, between pressure burden surface is not suitable for 'in loose outside close' problems.
Improper workpiece stamping direction.
Try to rush blank is too soft, low strength of materials, the blank size is too small, cannot be hid.
Blank positioning is not stable, can not lead to partial pressure, pressure is expected to face shape is undeserved, cause uneven material.
The wrinkling more than scrap of components, and precision stamping parts processing and the cost of raw material waste.
