Hydraulic press brakes can be used for heavy-duty work. They can also be customized to meet customer requirements, from high tonnage to long-length tandems and everything in-between.
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 repeatability and accuracy are exceptional. One job ran for five consecutive days. There was no difference in the time it took to bend the first part on day one and the last on day five. This, plus the shorter setup time, translate into higher profitability.
Tonnage is the force that the press brake applies to the material. It determines how much pressure can be applied to the punch during bending.
Tonnage refers to the press force applied by the brake. It is the pressure that can apply to the punch during the bending operation.
Do you need a strong and reliable machine for processing and bending metal sheets? At Gulf States Saw & Machine Co., our Single Cylinder and Dual Cylinder Y1+Y2 Hydraulic Press Brakes are capable of bending metal sheets and plates without hassles. They are strong and can be relied upon by fabricators for various form bending. The operation of our Hydraulic Press Brakes is quite simple as it basically requires that the material being worked on is fastened on the bed while the ram descends on it.
The motor within a mechanical press brake works by turning a large flywheel. The motor spins a large flywheel at high speed. The flywheel is controlled by the machine operator through a clutch. This sets the other parts in motion to bend metal. The mechanical press brake is simpler, especially in terms of its electronics. This makes maintenance and operation much easier. The mechanical press brakes can handle tons up to three times their intrinsic rating. Mechanical press brakes have one major drawback: the ram must go through a complete cycle once it is engaged. This cannot be reversed. This poses safety risks if an operator makes a mistake or places limitations on the machine. The possibility that the press brake could become locked if too much ram travel is one potential danger.
Standard is supported by a team of industry professionals which includes service engineers, sales consultants, product specialists and experienced application engineers. JMT has a dedicated parts and tooling section to keep your machines running at peak performance.
Bottom bending involves bending the metal sheet using a punch with a force that is 3 to 5 times stronger than air bending. This decreases or prevents the springback effect commonly associated with airbending. This begins with air bending and continues at the bottom with cold forging.
"The accuracy is amazing and the repeatability are excellent. Five days running a job, I saw no difference between the first and last parts bent on day one. The same thing happened on day five. This plus the faster setup time translate to higher profitability.
Raw power, heavy-duty bending performance, and improved technology – all in a cost-efficient package.
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.
You can use presses in sheet metal fabrication and production plants in many sectors such as automotive and aeronautics.
A motor in the device drives mechanical press brakes. The large flywheel spins at high speeds by the motor. The flywheel is controlled through a clutch by the operator. Once the clutch has been activated, the remaining parts are set into motion to bend and bend the metal. The mechanical press brake has an easier operation, thanks to its electronic components. Because of their mechanical design, they can handle tonnages up to three times greater than their inherent rating. However, mechanical press brakes are not able to be reversed. The ram inside the machine must complete the full cycle after it engages. This can cause safety issues if the operator is not careful and may also limit the machine's capabilities. If the ram travels far enough, the press brake can become locked.
Rare earth magnets can withstand pressures up to 9,000 lbs per square inch, but not for what you might think. The Internet has seen hydraulic presses crush things for a while.
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.
Hydraulic brakes are easy to maintain, provided you properly bleed the system and make sure there are no leaks.
The press brake is, in reality, one of the most difficult machines to master in the trade. Every sheet metal operation needs to bend.
