Common defects and the solution precision terminal
Precision terminal is the most commonly used metal electronic processing, machinery manufacturing field of electronic components.
Precision terminal processing is the use of mould making metal plate processing method with separation or forming.
Of the common defects are: precision terminal stamping die deformation of precision stamping parts, burr, etc. ;
The bending crack, warp and surface scratch, angular distortion, etc. ;
Deep drawing parts of flange buckling, deep drawing, wall wrinkling, deep drawing wall damage, cracking, etc. ;
Flanging crack, bulging not divide evenly, and so on.
Way to prevent and eliminate precision terminal defects are: precision terminal die design to have reasonable intensive interval value, radius and machining precision, etc.
Design of bending die, should take effective measures to reduce springback, and minus the springback amount on the mold;
Reasonable design of rounded corners, to prevent the bending crack.
Drawing the circle with prevent wrinkling, and pressure to moderate;
With proper lubrication drawing reduce the resistance and to prevent mould stick or make the workpiece to wear.
