The tonnage of the punching machine should be calculated reasonably based on the thickness of the stamping material and the stamping material. Below we will give a rough calculation formula, which is the perimeter of the stamping material (the shape of the stamped product, the total number of positions that have been cut by the cutting knife) x the shear strength (calculated from the hardness and material of the material) x the material thickness x 1.2 (this is a standard number, which is the spring force for mold return and shortage) x 1.3 (reserved amount), in order to calculate the tonnage of the stamped part. If you have more experience, you can also estimate it based on experience.high speed punch press

 However, because according to the needs of the mold, large molds generally require a larger punching pressure and installation also requires a larger workbench, so punching machines with larger shapes and larger punches have a larger tonnage; Mechanical punching machines require the use of flywheels to store kinetic energy, in order to convert it into greater force when cutting or deforming metal. Therefore, punching machines with large tonnage are generally equipped with larger and thicker flywheels, such as a 60 ton punching machine with a flywheel diameter of over 1 meter, while those with 40 tons are slightly smaller; In addition,high speed punch press, listening to the frequency (speed) of stamping during work can also distinguish the size of the tonnage, because the stroke of the small tonnage punch is short, the flywheel speed is also fast, and the stamping speed is also fast. Small tonnage can even be stamped once per second. Therefore, based on the sound speed of stamping, the tonnage size of the punch can also be basically determined; After working for a long time in contact with stamping, I have seen more of various types of equipment and can naturally distinguish them.high speed punch press
