How do you calculate the tonnage of a press brake?

Material thickness, die-opening width, and the length of bend are all in inches.

1. Forming tonnage = {[575 x (Material thickness squared)] /Die-opening width/12} × Length of bend × Material factor × Method factor × Multiple-bend tooling factor.
2. Material factor = Material tensile strength in PSI/60,000.

How do you select press brake tooling?

④ When using the press brake toolings, choose the right upper die and lower die according to the sheet metal hardness, thickness, and length. Generally, the slot width of the lower die should be 5-6 times the thickness of the metal plate, while the length should be longer than the sheet.

What is the minimum top tool radius of a bending forming tool?

Minimum punch radius ≥ 63% of the material thickness The punch tip radius should be no less than 63% of the material thickness. The smallest inside radius that can be achieved by air bending sheet metal is . 63 x material thickness.

How is bend allowance calculated?

Bend Allowance = Angle * (π / 180) * (Radius + K-factor * Thickness). So the flat pattern length is 1.625” + 2.625” + 0.475″ which is equal to 4.725″. So if you add up the flat length of all the flanges and add one Bend Allowance for each bend area you have the correct flat length of the part.

How tonnage is calculated?

Tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.

How to calculate press brake tonnage in your hand?
