The tonnage of the punch press is mainly related to the force required for stamping. Punching has punching force, and pulling also has pulling force. If the tonnage is not sufficient, the pulling will not be in place.

The result obtained by multiplying the above several factors in a stamping factory is the punching force, but the unit is in newtons. To convert it to tons, divide by 9800 to obtain the basic tonnage. Then, considering the safety margin of punching and the force required for unloading, pushing, and other operations, divide this tonnage by a coefficient of 0.7 to obtain the tonnage of the machine tool.
