The use of press brakes is common in sheet metal and production plants in many areas, including automotive and aeronautic.
Bottom bending uses a punch to bend the metal sheet at a high rate (3 to 5 times more than airbending), which reduces or eliminates the springback effect common with airbending. The process starts with air bending, and then goes on to cold forging at the bottom.
Hydraulic press brakes make heavy-duty work possible and can be tailored to address the most varied customer forming needs, including long length, tandem and high tonnage.
You get raw power, heavy-duty bend performance, and better technology all in one cost-effective package.
This unique technology makes it possible for press brake operators with all levels of skill to achieve efficient and quality results.
As part of our Perfect Machine Process, every Standard hydraulic press brake is rigorously inspected in our Rockford, Illinois, facility so that it’s ready for seamless installation in your shop.
The bending angle must be adjusted according to the metal springback and the margin must also be calculated. For example, a 90deg bend requires that the punch be lowered to 85deg.
At Gulf States Saw & Machine.Co , we carry a wide variety of hydraulic press brake models to meet the unique needs of the various businesses we serve throughout the country. Our press brakes range in size from 22 tons to 440 tons and bed lengths from 4’ to 13’ with CNC or manual controls. In addition to our standard inventory, we can accommodate custom orders for specialty length requests and tonnage. All of our press brakes include safety devices and a rear safety cage that disables the machine when opened for easy and secure maintenance. All electrical components use industry-standard parts, which are readily available in our Memphis, TN warehouse. Download a pdf for more details on each model.
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.
This type of bending is used most often for sheet metal work because it can be used on machines with smaller capacities than bottom bending which requires more force.

Once these characteristics have been determined, you must then calculate the tonnage required for the bending operation.
In air bending, the end of the punch and the 2 edges of the V allow the sheet metal to be bent. But this type of bending means there is a spring back effect of the work piece. As the bending force is weaker, the metal sheet springs backwards like an elastic when the punch is removed.
The tonnage is the press force of the press brake. It determines the amount of pressure that can be applied by the punch during the bending operation.
Rapid braking Can cause slipping or sliding if you brake too fast. Slowly brake by gently putting your foot on the pedal. You should leave enough space between you and the driver in front to ensure a generous stopping distance.
Five Types of Hydraulic Presses: Why You Need Them
Answer: Bottom-bending can be accomplished with aluminum grades that are softer, such as H series. Here are some best practices to help you make sure your press brake operators understand bottoming. 1.
Material Type and Thickness Maximum Material Length. Complexity of bends. Accuracy of Bend. Per day, number of parts required. Each day, there are approximately 2,000 parts/tooling changes. Level of skill for press brake operator.
