A press brake is a machine tool used for bending metal parts and sheets up to 20 mm thick. It is composed of a V-shaped or U-shaped die (depending on the desired bending shape) and a punch. The material to be bent is placed on the die and pressed by the punch which then bends the sheet to the selected degree.
Adjust the bending angle in accordance with the metal spring back, and then calculate the margin. Accordingly, for example, 90deg bends, the punch should be reduced to 85deg.
These machines are fast and efficient, as they run faster, more efficiently, and with greater reliability than their predecessors.
This type bending is most common for sheet metal workers as it is compatible with machines with smaller capacities.
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.
Machines that press brake sheet metal are used to form long sheets. These sheets are commonly used in manufacturing, for industrial applications, or to make components for other devices. Most press brakes have a rating based on their pressability and their bending length. This information is expressed as numbers (e.g., total pressure per inch, or pounds of pressurized material per inch). They are available in many sizes and can often be equipped with additional tools and add-ons to make custom components. The two main types of presses brakes that you will find are hydraulic and mechanical. In the following sections, we will explain the main features and distinguish between the two types.
The Hydraulic Press Brake's tonnage, also known by the Press Capacity, determines the work-piece size that can be processed. A press brake can also deliver the unit force measurement. This is what bends work-pieces into the desired/specific degrees. The tonnage range for our Press Brakes ranges between 30 tons and 3000 tons. While the bed lengths range from 4 feet to almost 30 feet, they can accommodate up to 30 tons.
Our Servo Hydraulic Press Brakes are powerful efficient metal benders with up to 66% lower power consumption during stand by and 44% lower energy use during the bending cycle. Ram movement on our servo brakes is powered by AC Servo "electric" motors driving hydraulic oil "on demand" in line with variable speed pumps. Our servo press brake achieves a significantly lower cost per part by using our highly sophisticated advanced technology that synchronizes the powerful forces of electronics, electric power and hydraulics only when it's needed. You won't find a quieter, more energy efficient or more accurate press brake anywhere.
Flexible and reliable bending performance, all with the patented HEXA(r) frame – all in a cost efficient package
Do you require a machine capable of processing and bending steel sheets? Gulf States Saw & Machine Co. offers single and dual cylinder Y1+Y2 hydraulic press brakes that can bend plates and metal sheets quickly and easily. They are strong and can easily be relied on by fabricators for different forms of bending. Hydraulic Press brakes are easy to operate. It basically means that the material being used must be attached to the bed while it descends.
Our energy-efficient, all-electric BB series press brakes come specially designed with a collection of ultra-modern, performance-enhancing features that are perfect for meeting and exceeding the demanding requirements facing today’s production machinery experts.
Standard press brakes are reliable and dependable, day after day. It is easy to use the controls, which are extremely user-friendly. Our press brakes can handle a wide variety of materials, including soft brass as well heat-treated aluminum alloys and stainless steel.
When calculating the margin, other elements must be considered, such as thickness of punch blade, fold length, and opening of V.
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.
How does a hydraulic press brake work? Hydraulic press brakes use the power of a hydraulic motor, applying force to the metal and compressing it into a die that forms the shape. The shape of the die determines the final shape achieved by the metal bending process.
There are two types of primary press brakes: electronic and hydraulic. Hydraulic presses brakes are the most common and oldest type of press brakes. Hydraulic press brakes are capable of handling the most difficult workloads.
Semi-trucks use compressed air for their brakes instead of hydraulic fluid. Semi-trucks have a lot of weight so they need air to brake.
4. Choose the correct upper and lower dies for your press brake toolings based on the sheet metal hardness, thickness, length, and other factors. The slot width of the lower den should be between 5-6 times and 6-8 times the thickness of a metal plate. The sheet should have a longer length.
