Hydraulic Press Brake Tonnage Calculation

Hydraulic Press Brake 14 Foot

The first generation of press brakes had only one axis that could bend. These machines were far less flexible than modern machines that have 12 or more programmable movement axes. Modern presses brakes are extremely precise and can create visual representations of the final result to assist the operator. The setup time has been greatly reduced by modern computers. These computers can quickly determine the optimal settings based upon materials used, their dimensions, and desired results. Back in the day, these calculations were done manually.

Our BB series has the right bending tools for you.

A press brake is a machine that bends metal parts and sheets up 20mm thick. It consists of a U-shaped or V-shaped die, depending on the desired shape of bend, and a punch. The material to bend is placed on the die, and the punch presses it to bend the sheet to the desired degree.

Two methods can press brakes bend steel. The first is bottom bending, where the ram presses the metal to its bottom. Bottom bending allows for precise bends, and less reliance on the machine's press brake. Each tool has its limitations. They are designed to create a particular bend and you will need a different one for each angle. The bottom of the die and the ram are separated by an air pocket when air bending occurs. This allows for the operator to account for any material spring back. These types of dies need to only be changed if there is excessive material thickness. Air bending has a drawback. Because the thickness of the material can affect the accuracy, the ram needs changing accordingly.

Our machines are built with industry-leading production capabilities and feature intuitive operator controls that reduce stress for all skill levels.

Therefore, adjust the bending angle to match the metal spring back and calculate your margin. The punch should be adjusted to 90 degrees for a 90 degree bend.

How To Hydraulic Brakes Work

How To Hydraulic Brakes Work

The use of press brakes is common in sheet metal and production plants in many areas, including automotive and aeronautic.

Air bending is done by bending sheet metal at the ends of the punch and 2 edges of V. This type of bend also creates a spring effect in the work piece. Because the bending force in this case is weaker, the metal sheet can spring backwards as if it were elastic.

Sheet

There are two ways press brakes can bend metal. The first is called bottom bending because the ram will press the metal to the bottom of the die. Bottom bending results in highly accurate bends and relies less on the press brake machine itself. The downside is each tool is they're made to create one specific bend, so you’ll need to purchase a new one for every angle you want to make. Air bending leaves an air pocket between the ram and the bottom of the die. This allows the operator to accommodate for any spring back the material might provide. These types of dies only need to be changed if the material’s thickness is too much. Air bending’s drawback is the accuracy of the angle is affected by the material’s thickness, so the ram needs to be changed out accordingly.

These machines are fast and efficient, as they run faster, more efficiently, and with greater reliability than their predecessors.

Warning: incorrect tonnage (too high or low) can damage your press brake or the part you are bending. To calculate the tonnage of your press brake, refer to the operating manual or a tonnage table.

Why hydraulic brakes are better

Gulf States Saw & Machine has the right tools for you, whether you need precise computer-controlled measurement or simple, no-nonsense bends. Co offers hydraulic press brakes of varying sizes in two excellent options. All at an affordable price. For a quote on a machine, contact our team today.

Standard currently produces the largest range of hydraulic press brakes. Our ADR 5 axis CNC hydraulic press brake series offers 20 models. They range from small press brakes that are 4 feet long to larger press brakes with bending lengths of up to 20 feet. There are 7 different tonnages, ranging in weight from 66 to 443. The ADS series, which is more advanced and comes with 14 CNC axis, has 32 models. It can bend metal from 6 feet 8 inches to 26 feet 5 inches. The ADS series machines offer top-end precision and powerful metal bending capabilities in 13 tonnages that can handle up to 3,300 tonnes. We also offer the PBF series to customers who need a simple press brake. The sophisticated AD Servo brakes, which have a combination hydraulic configuration and ball screws, are quiet and energy efficient. Standard also brings to market the FBS Series, which stands for "flexible bend solutions" press brakes. FBS series brakes can be made to high-tonnage specifications to meet customer requirements. They can run tandem or trio press brakes and have material automation and handling options.

The CNC Press Brake is fast to set up and has a repeatability of +/–0.0004 inches. This will allow you to reduce the time it takes to make parts.

Nearly all modern car crushers use hydraulic presses to crush cars. A pump pushes hydraulic fluid through large cylinders to power a large motor. Using principles of force-multiplication, a hydraulic system can generate over 2,000 psi and impart more than 150 tons of crushing force onto a pile of scrap cars.

With about 70 lbs, the average person can push on the brake pedal. You can apply the brake pedal with about 70 lbs. To stop a moving vehicle disc brakes require 800-1200 psi at their calipers. All parts of the system amplify the force you apply to the pedal.
