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.
It is a unique technology that allows press brake operators of all skill levels to produce high quality, efficient results.
G37 Brake Pedal StopperIn 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.
Warning: Incorrect Tonnage (too high/low) could cause damage to your presses brake or the part that you are bending. The operating manual and a tonnage chart will help you calculate the tonnage for your press brake.
The PA Plus series combines versatility and functionality in one powerful package. The PA Plus series has a wide variety of accessories to make it a customized solution.
The use of press brakes is common in sheet metal and production plants in many areas, including automotive and aeronautic.
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.
The possibilities are unlimited with our top end precision press brakes that feature, better controls, more axes, faster setups, faster part production, large daylight openings and large working areas. Features include a stable and fast AC servo motor-driven back gauge system and outboard mounted long ram guides (which provide stability while allowing full length between the frames for acute angle bending).
Once these characteristics are determined, it is time to calculate the tonnage necessary for the bending operation.
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.
A Mitsubishi automatic tool changer (ATC), fitted to a press brake, stands out in many ways.
It's finally possible to find a high-quality, durable press brake solution that is both simple to use, and easy to love.
Our BB series has the right bending tools for you.
The next step is to determine the characteristics that will be used to calculate the part bend. For example:
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.
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 bending length of the press brake should be slightly longer than the sheets you wish to bend. The press brake can become damaged or destroyed if it isn't the right size.
Hydraulic brakes use brake fluid within sealed tubing between the lever and caliper. This fluid is usually either DOT fluid, or mineral oil/fluid. Both fluids can cause contamination over time so it is important to flush the system and have fluid changed periodically.
F1 brakes can be difficult because all of the driving force must be generated by the driver. There cannot be power assistance. The pedal acts almost as an on/off switch, and there is rarely any need to use gentle braking.
