The frame of press brake is welded with steel, ensuring high rigidity and machining accuracy.
To avoid cracks on the radius, it is essential that the press brake is carried out orthogonally to the rolling direction.
The press brakes are controlled by mechanical systems, a crank connecting rod system, and hydraulic pistons. Press brake can be operated by manually or computer, called CNC press brake.
The metal sheet is deformed by a bending force of press brake which necessarily exceeds the limit that the elasticity of the material imposes.
Also, the press brakes are equipped with a punch mounted on the movable part. This part of press brake is composed of a die and a blank holder piston with the same functions and characteristics of a mold for a press.
Press brakes contain a work table, a clamping plate, and supporters. The worktable consists of a base and a pressure plate, which is attached to the supporters. As working with a press brake, adjust the bending angle and dimensions continually.
The forming of press brake greatly depends on operator’s skill. Therefore, varying levels of quality and productivity are to be achieved by two different operators.
Press brake is available for bending sheet metal. The sheet metal will play a important role in the manufacturing industry. These sheet metals processed by press brake are used in home appliances, vehicles, heavy equipment.
Before the right sheet metals are formed, press brakes should first consider the right die design to produce the right sheet metal. Press brakes are used in different forming works with the right die design like V dies, rotary bending dies, acute angle dies, and radius dies.
In a mechanical press brake, power is added to a flywheel with an electric motor. A clutch matches the flywheel to power a crank mechanism moving vertically. Accuracy and speed are two advantages of the mechanical press brake. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam.

How to adjust the gap between blades of CNC press brake?
What should be considered when using CNC press brake?
Close the rear protective door of the CNC press brake. Turn on the power. Turn on the switch on the control panel of CNC press brake. Then, start the oil pump. The CNC press brake does not operate at this time. Release all emergency stop switches.
Adjust stroke. Pay attention to adjusting the stroke when using it. You must test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise, it will cause damage to the CNC press brake. The adjustment of the stroke also has electric quick adjustment.
For the selection of bending notches for CNC press brake, a notch with a width of 8 times the thickness of the plate should generally be selected.
Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.
Press down the blue "reset" button on the pedal and the "reset rearguard" button on the electric box, ensuring that the two blue reset indicator lights are off.
Turn the function forwarding switch to the "auto" position and press the motor start button after the controller self-test is over.
The CNC press brake finds the reference point and loads the corresponding bending program. Ensure that the mold installed in the CNC press brake is consistent with the programmed mold. Ensure that the sheet material is consistent with the programming page.
Remove the lower blade of CNC press brake and clean it piece by piece. Select one side to install tightly. Check the straightness of the blade in the horizontal and vertical directions.
Remove the upper blade of CNC press brake and clean it piece by piece. Then, the operation is same with that of the lower blade.
The upper blade is fixed. We adjust the blade gap by adjusting the lower blade.
The left and right screws of the lower blade increase the clearance. Loosen the four bolts on the table of the lower blade.
Manually turn the upper blade down to the proper position. The operator adjusts at the blanking area of the CNC press brake.
Use a feeler gauge to roughly adjust to 0.5mm from the unoccupied part of the upper and lower blades.
Manually turn the blade to the middle position and adjust it to 0.5mm.
Manually turn the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5mm.
Manually turn the upper blade to the proper position and start fine adjustment.
Before working, you must check the surrounding area of CNC press brake for any objects that may cause harm to it. Make sure the surroundings are clean, especially backgauge. Check the position of the oil mark in the oil tank. Check the hydraulic part for leaks.
The CNC press brake should be operated by professors. The operators must wear the corresponding labor protection supplies.
