Is to make the blanking and punching blanking and punching cr2450 batteries shrapnel stamping blank separation process.
Blanking and punching process are exactly the same, just different purposes.
Blanking, isolated part is finished, the rest of the surrounding is waste;
Punching hole is to obtain, by punching sheet metal is finished, the separated part is waste.
Blanking and punching are collectively known as blanking.
Blanking punch and the die has a sharp edge, there are equivalent to the thickness between the punch and die - 5%
10% of the gap, in order to assure neat incision and less burr.
Cr2450 battery shell workpiece bend is get different shapes of corners.
Bending die on the workpiece bending part work must have the appropriate radius r, to avoid the workpiece bending crack.
Deep drawing, deep drawing is the stamping materials stamping parts processing.
Deep drawing die of the punch and die edge should be rounded to avoid artifacts is cracking.
Between the punch and die to periods of is a little bigger than the thickness of the sheet metal, in order to reduce the friction.
In order to prevent fold, cr2450 batteries shrapnel billet edges need clamp pressure.
