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.
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.
Imagine giant, intelligent, large press brakes with a vast range of tonnages, lengths, loading/unloading metal material handling and an infinite number of bending lengths. Our high tonnage mega presses brakes feature an advanced engineered technology "box-construction" frame design. This gives our mega brakes one of the strongest and most stable machines in the world. All of our references around the globe are impressed by the exceptional stability and rigidity that our large high tonnage presses brakes have, thanks to our box-construction frame design. Our high tonnage presses are designed to minimize large pieces being handled before, during, or after the bending operation. This allows for the next process to be respected.
This dual-drive hybrid makes short work of any project with long term, high speed, energy-efficient operation.
The motor inside a mechanical press brake operates via a motor. This motor spins an enormous flywheel at high speeds. The machine operator controls the flywheel via a clutch. A clutch then sets the other parts in motion and bends the metal. The mechanical press brake, with its electronic controls, is much simpler and makes maintenance and operation simple. A mechanical press brake can handle tonnages that are two to three times larger than their intrinsic rating due to its design. The downside to using mechanical press brakes, however, is that the machine's ram must complete its full cycle before it can be reversed. The operator can make mistakes, which could lead to safety concerns. A potential danger is that the press brake may become locked if it travels too far.

Hydraulic Press Brake Preventive MaintenanceThe sheet metal can be bent by air bending when the punch ends and the V edges are connected. However, this type of bending has a spring back result. When the punch is removed, the bending force is lower and the metal sheet springs backwards just like elastic.
Our press brake machines are backed by Standard Industrial's reputation as a durable and repeatable machine. This gives them an advantage over other models.
It has been said, "The little guys sometimes punch well beyond their weight class." Our 4 foot small press brake proves this. This compact bender features a CNC controlled back gauge on the X axis, tangs for euro or american style toolsing, an LED rear light, two sliding front supports with a line rail and a dual station with a palm/foot switch. This compact, precise small press brake is sure to impress.
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.
Once these characteristics have been determined, you must then calculate the tonnage required for the bending operation.
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.

There are two methods that press brakes can bend steel. The first, or bottom bending, is when the ram presses metal to the bottom. Bottom bending can produce precise bends and is less dependent on the press brake. The problem is that each tool is designed for a specific type of bend. You will need to purchase a brand new tool for each angle. Air bending creates an air pocket between the die's bottom and the ram. This allows the operator flexibility in accommodating any spring back provided by the material. These types are only necessary to be replaced if the material is too thick. The drawback of air bending is its inability to accurately bend the material. This means that the ram will need to be changed accordingly.
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.
Your car will struggle to stop if your speed is lower than the lowest gear. This can be avoided by pressing the clutch to ensure that the engine does not depend on the transmission. Then, start braking.
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.
Hydraulic brakes are more efficient than mechanical disc brakes. This means that you will need to apply less pressure to the lever for equal braking power. This allows for better modulation.
Modern manual transmissions can be used to skip gears while going up or lower. You can, for example, change the gears when you accelerate. However, 3rd may be slower due to low engine revs.
