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.

Laser cutting machine has become an indispensable tool for metal sheet processing enterprises. However, when using laser cutting machine for processing, we encounter some problems, like the large gap of steel plate and the reduced accuracy of the processed components.
A lot of heat will be generated, which may deform the surface of the thin plate and the processed workpiece.
The focus of the laser cutting machine and the surface of the processed object change, causing the large cutting gap or inaccurate processing.
An error will occur due to the incorrect position of the worktable. If the laser cutting machine is not installed firmly and the parts are worn for a long time, the worktable surface will be uneven. This imbalance will also cause problems between the thin steel plate and the laser focus, resulting in excessive cutting gaps or reduced processing accuracy.
One of the biggest advantages of laser cutting machine is to cut a wide range of materials.
Laser cutting machine can cut all types of metals, ranging from mild steel to stainless and non-ferrous metals. More reflective metals like aluminum are more difficult to cut. The thickness of the metal can be up to 30mm. The maximum thickness depends on the laser cutting machine.
Different types of wood are suitable for cutting like plywood and MDF. However, be aware of oils or resin to avoid fire.
Paper and cardboard are also suitable for laser cutting machine, where the popular wedding invitations are made.
Plastics also leave a great finish when using laser cutting machine that the edges are melted in a polished way.
POM is a highly utilized plastic in the engineering sector, finding usage in gears, guiding and sliding elements, medical instruments, and food packaging. It can also be cut by laser cutting machine.
Cutting glass is a seemingly impossible task because of its fragile and reflective properties. However, laser cutting machine can engrave glass.
Replace the circulating water once a week. Make sure that the laser tube is filled with circulating water before the laser cutting machine works. It is recommended to use pure water and keep the water temperature below 35°C.
Long-term use of the fan will accumulate a lot of solid dust, making the fan generate a lot of noise and not conducive to exhaust and deodorization. Disassemble the air inlet and outlet pipes on the fan. Remove the dust inside. Turn the fan upside down and pull the inner blades until they are clean.
It is recommended to clean lens before laser cutting machine works every day. There are 3 mirrors and 1 focusing mirror on the machine. The lens are easily stained with dust or other contaminants, which can cause laser loss or damage to the lens. Just rotate to wipe from the center to the edge with the lens wiping paper.
After the motion system has been working for a period of time, the screws and couplings at the motion connection will loosen, which will affect the smoothness of the mechanical motion. Observe whether there are abnormal noises or phenomena in the transmission components.
It is recommended to check whether the optical path is normal before each work.

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.
