Ranging from entry-level hydraulic all the way up to heavy-duty, fully customized solutions that cover any of your requirements for sheet metal forming, these press brakes represent the apex of pounds-to-performance for industrial bending.
Once you have established these characteristics, then you need to calculate how much weight is required for the bending operation.
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.
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.
There are also the BH series "hybrid", which proves once again that not all hybrid press braking systems are created equal. These machines are the third generation and feature a dual-drive design that combines hydraulic and electric bending. They offer superior productivity, precision and reliability and energy savings.
We also have a range of Press Brakes designed on the hydraulic control system. Its bending capacity is capable of handling thick work-pieces. As a result of its tonnage capacity, it works efficiently on any thick metal material. This range is built in either Single Cylinder or Dual Cylinder Y1+Y2 formats and requires no complex operation to function. Materials that can be processed on our Press Brakes include steel, brass, metal sheets, and aluminum alloys.
Finally, there is a press brake solution for heavy duty that is both user-friendly and loveable.
According to the metal springback, you must adjust the angle of the bend and calculate the margin. So, for example, a 90deg bend must be bent, the punch must be reduced to 85deg.
In bottom bending, the punch curves the metal sheet with a high force (3 to 5 times greater than air bending) which reduces or even prevents the spring back effect generally associated with air bending. The process begins with air bending then continues with cold forging carried out at the bottom of the V.
High productivity, high-performance bending, and intuitive operation all in a cost-efficient package
Every Standard hydraulic brake is subject to our Perfect Machine Process. Each Standard hydraulic brake is rigorously checked in Rockford Illinois before being installed in your shop.
Our manual control push brakes are suitable for industries and jobs that don’t require the precision and detail achieved by CNC controls. The manual press brakes include all the safety features of CNC models. However, manual presses are more powerful and easier to use than CNC models. They feature a front operated power back-gauge, ram adjust with digital readings, and fine adjustment handswheels for both. Our models range from 22 to 44 tons.
When calculating the margin, other elements must be considered, such as thickness of punch blade, fold length, and opening of V.
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.
The most common reason for a soft/spongy pedal is air in the brake lines. Breathing in air can cause the brake pedal to feel soft or spongy. If your brakes feel spongy or soft, it is time to flush or change the brake fluid.
The press brake is usually narrow and long, so large sheets of sheet metal can easily be bent by it. The press brake bends sheet steel by placing a punch on sheet metal placed on top of a tool. A press brake can bend the metal several times until it reaches the desired shape.
A hydraulic press can cost anywhere from $10,000 to $5 million depending on its capabilities and age.
To pump hydraulic fluid into the system, pressure is applied by hand. The pressure is transferred to another area, and the resultant force can reach 25 tons.
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.
