### Bending Basics Why tonnage matters

Whether you are using a tonnage chart or calculating the tonnage requirements manually,you need to know how to apply the information.The jobs tonnage requirements should not exceed the tonnage capacity of the press brake or the tooling.Press Brake Tonnage Capacity.Before continuing,we need to define some terms,the first being deflection.Bending Chart,Tonnage Charts,Press Brake Tooling About Ashmores Press Brake Tooling Limited.Ashmores are the UK's longest established Press Brake Tool manufacturer established in 1919.We offer Press Brake Tooling to suit all models of press brake the range includes tools to suit all Euro style machines,Trumpf / Wila,Bystronic,LVD and many more.Calculate the Press Brake Tonnage for Any Part - HARSLE Tons per meter (t/m) = Thickness (in mm)² x 1.65 x UTS (in Kg/mm²) / V Opening (in mm) The number 1.65 is determined by the friction of a certain material (which in our case is metal) to determine when the bridge falls down.Without the 1.65 factor this same formula would tell the exact maximum load that our sheet metal bridge can support.

### Calculating Required Tonnage for an Off Set Die

Jul 24,2012·I started with the tonnage chart here PRESS BRAKE TOOLING I figure if I am using a joggle die,I am really making two bends.Since the two bends are 3/8'' apart,then the equivalent bottom die opening is 3/4''.The chart reads that to bend 11 Ga.Mild Steel with a 3/4'' Female Die Opening,it is 10.5 Tons Per Foot.How to Calculate Bend Allowance for Your Press Brake Although you may find several different formulas that claim to calculate the Bend Allowance (See Bending Definitions),they usually are the same formula,only simplified by filling in the angle or a K-factor.Oh,and yes,you do need to know the K-factor to calculate the Bend Allowance.Lets start with a simple L bracket.How to Calculate Bend Allowance for Your Press Brake The formula (See Bending Formulas) is Bend Allowance = Angle * ( / 180) * (Radius + K-factor * Thickness).Plugging in our numbers,we have Bend Allowance = 90 * ( / 180) * (0.250 + 0.42 * 0.125) = 0.475.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
