Press brake is a kind of general equipment for bending sheet. Press brake can press metal sheet into a certain geometric shape by using a simpler general mold. For sheets of different thicknesses, V-groove lower molds with different opening sizes should be selected. The required bending force can be obtained from the bending pressure gauge.

1. The oil cylinders at both ends of the body of the press brake are arranged on both sides of the slider to directly drive the slider. A mechanical stop is arranged in the oil cylinder to control the bottom dead center position of the slider. The upward end position of the slider is adjusted by the stop beside the travel switch.
2. The bottom dead center of the slide block of the press brake and the end position of the back gauge stroke are shown by the corresponding rotation number table.
3. The torsion shaft of press brake is used to forcibly synchronize the two ends of the sliding block and can withstand a certain amount of eccentric load.
4. The upper part of the press brake is equipped with a precision compensation mechanism, which can make the workpiece obtain consistent bending accuracy over the entire length.
The accuracy of press brake is a factor that needs to be carefully considered. It is this factor that determines whether you need a CNC or manual press brake. If the press brake requires in the range of 1° and cannot be changed, you should choose CNC press brake. The repeatability of the slider of the is in the range of 0.002 inches with the deviation of 2 to 3°under the condition of using a suitable mold.
The wear of each mold must be checked by measuring the length from the front end of the punch to the shoulder and the length between the shoulder of the die. The deviation per foot should be around 0.001 inches and the total length deviation should not be greater than 0.005 inches.
When free bending is adopted, the bending radius of press brake is 0.156 times of the opening distance of the die. The opening distance of the die should be 8 times the thickness of the metal material. If the bending radius is less than the thickness of the material, a punch that a radius at the front end is smaller than the thickness of the material must be used.
The press brake is a machine that can bend thin plates. Traditional processing methods in the metal sheet workshop include plate shearing, punching and bending. A large number of molds are needed. Adapting to modern metal sheet processing, press brake come into being, reducing production costs and improving processing technology.
With the development of technology, the modern production mode puts forward higher requirements for the production equipment. In the past, the press brake had to bend the entire batch of workpieces when performing multi-pass bending processing, which required continuous work of refueling. However, the stopper and the slider stroke of press brake can be controlled, which can continuously bend batches of workpieces in multiple passes. The press brake ensures that the workpieces have high forming accuracy and high degree of identity, which can greatly improve production efficiency and have a promising development prospect.

Bending is a processing technique of deformation and forming after shaping. It is performed industrially with press brakes. Press brake can perform rectilinear and parallel folds on pieces of medium-large dimension. The minimum radius relies on the thickness and type of material to be bent.
Why we use press brake?
How does press brake work?
What are the uses of press brake?
Press brake uses the electro-hydraulic servo system to control the two-cylinder synchronization. Press brake cooperates with the international standard grating ruler to form a fully closed-loop control. The synchronization has high accuracy and high level of the bending and repeat accuracy.
Press brake can be equipped with hydraulic upper mold automatic clamp, quick clamp, or slot type lower mold to reduce the labor and improve efficiency.
Press brake is equipped with high-quality linear guides and ball screws to ensure the accuracy.
Press brake has flexible operation mode, not only solving the processing of ultra-long plates by dual-machine linkage, but also processing short parts by single-machine operation. Press brake improves the utilization rate and reduces energy consumption.
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.

CNC press brake is mainly used to realize the bending of metal cabinets, box shells, U-shaped beams and rectangles of various geometric shapes. The plates can be stretched, grooved, punched, and corrugated by the CNC press brake. The CNC press brake processing has the advantages of high bending straightness without marks, peeling or wrinkles.
What is the difference between CNC press brake and electro-hydraulic press brake?
How to choose a suitable CNC press brake?
How to improve the lifespan of CNC press brake?
The CNC press brake uses a torsion axis to link the left and right swing rods to form a torsion axis, forcing a synchronization mechanism to move up and down the cylinders on both sides. It is a mechanical forced synchronization method. The parallelism of the slider cannot be automatically checked and adjusted.
The electro-hydraulic press brake installs a magnetic scale on the slider and the wall plate. The numerical control system can analyze the synchronization of the two sides of the slide through the information feedback from the magnetic scale at any time. If something wrong, the numerical control system will be adjusted by a proportional electro-hydraulic servo valve to synchronize the strokes on both sides of the slider. They constitute the feedback closed-loop control of the electro-hydraulic press brake.
The parallelism of the slide block determines the angle of the workpiece. The CNC press brake keeps the slide block synchronized by the machine. There is no real-time error feedback. However, its eccentric load capacity is poor.
The electro-hydraulic press brake is the system through the proportional electro-hydraulic valve group to control the slider synchronization. The magnetic scale reports real-time error.
The CNC press brake does not have a control system and V-axis compensation. You can only stake out and do trial bending first.
The electro-hydraulic press brake is controlled by a professional numerical control system with V-axis compensation. There is a simulated bending function that no stakeout is required.
When purchasing CNC press brake, consider the production of parts. It must be able to complete the processing tasks. The workbench must be the shortest and the tonnage can be the smallest. The material grade and the maximum processing thickness and length should be paid attention to.
The shorter workbench, the fewer shim adjustments to produce qualified parts. Reduced shim adjustment shortens preparation time.
When free bending is used in CNC press brake, the bending radius is 0.156 times the opening distance of the die. The opening distance of the die should be 8 times the thickness of the metal material. If the bending radius of CNC press brake is almost as small as the material thickness, a bottomed die must be formed.
In order to choose the lowest tonnage specification, it is best to plan for a bending radius larger than the thickness of the material, using the free bending method.
The accuracy is the most important factor affecting your choice. It determines whether you need to consider a CNC or a manual press brake. If the bending accuracy requires within 1° and cannot be changed, you must focus on the CNC press brake.
Create a uniformly distributed machining allowance for each type of bending in each bending process. The main CNC press brake mold should be as close as possible to the final shape of the mold in each process.
The evenly distributed machining allowance of the CNC press brake mold ensures a constant and high productivity and a safe bending process. When the angle is constant, the bending speed and feed rate can also be kept constant at a high level.
Continuous cutting of CNC press brake should be maintained for as long as possible during the bending process. Otherwise, it will increase the thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more beneficial.
