Therefore, CNC press brake is a product that meets the energy saving requirements. The servo motor has a higher degree of controllability so that it can be well adapted to the production needs of the modern industry.
The efficiency and the profitability of a CNC press brake are measured by the number of completed and correct parts produced in a given period of time.
Operators need to know CNC press brake completely. They also should know material type, thickness, flange dimensions and tolerances, angles and angle tolerances, and inside radius of angles.
The choice of tool is based on the drawing. Air bending, bottom bending, and coining are available. Select the tool that is at least as accurate as the specified type.
Tonnage charts are available for air bending. For bottom bending, a good tonnage may be four times than that of the air bending. Coining requires eight times the air bend tonnage.
If you have two or more CNC press brakes, make sure to choose the best-suited one. Remember that air bending cannot overload a CNC press brake.
Determine tooling position on the bench. If the tonnage requirement exceeds the concentrated load limit in the center of the CNC press brake, it can be off-center.
Install the tooling and align the upper and lower.
CNC press brake should be programmed properly, which is very quick.
Bend materials only after completing a good test bend. If something wrong, correct the program until a good part has been formed.

Shearing machine is very important in the era of scientific and technological development. In terms of work efficiency, many enterprises have seen the light in the production of finished products due to shearing machine. They play a very important role in processing such as metal and non-metal plates.
Why is shearing machine widely used?
What is the structure of shearing machine?
How does shearing machine work?
The shearing machine plays a role in fast cutting for some panels that need to be processed. The traditional cutting wood is more often used by the see-saw method, which has slow speed and makes people tired. The saw blade is very easy to wear and break. However, the use of shearing machine gives a feeling of high efficiency, convenience and the high quality. Because the shearing machine has two blades merged into one joint, which can be adjusted, it can be cut at any angle, even if the plate is bent and deformed.
The main structure of the shearing machine is generally composed of the body, the transmission system, the knife holder, the presser, the front stopper, the rear stopper, the supporting device, the blade gap adjustment device, the light alignment device, the lubrication device, electrical control devices and other components.
The shearing machine is welded by steel plate, which has good rigidity. The two cylinders are fixed on the left and right columns. The auxiliary tool holder is provided on the working table to facilitate the micro adjustment of the lower tool holder. There is also a feeding ball on the working table of shearing machine.
The upper tool holder is a steel plate welded structure. It uses the eccentric sleeve as the fulcrum to swing back and forth under the drive of the left and right oil cylinders and the accumulator return cylinder to complete the shearing. The vertical supporting surface of the blades of shearing machine forms an arc-shaped curve to ensure the consistency of the gap between the upper blades during the cutting process.
The material pressing device is composed of several material pressing oil cylinders installed on the front supporting surface of the frame. The head presses down after overcoming the tension of the relay spring to compress the sheet material. It resets by the pulling force of the tension spring.
The shearing machine should be able to meet requirements of the straight and parallel shearing surface of the sheared sheet. Shearing machine should minimize the distortion of the sheet to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, while the lower blade is fixed on the workbench. A holding ball is installed on the workbench so that the sheet material will not be scratched when performing. The back gauge is used for positioning the plate that the position can be adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during shearing. The guardrail is a safety device to prevent work-related accidents. The returning generally relies on nitrogen, which is fast and has little impact.
The movement of the shearing machine is that the belt on the motor transmits the torque to the large pulley shaft. The large pulley shaft has a small gear at the other end. The power is transmitted from the small gear to the large gear on the shearing shaft. The large gear shaft is equipped with a clutch mechanism. When the shearing machine is operated, the large gear drives the shearing shaft. The eccentric wheel on the shearing shaft drives the upper knife holder to move up and down linearly through the connecting rod to shear.

Shearing machine is a machine that uses one blade to make a reciprocating linear motion relative to the other blade to cut the plate. A shearing force is applied to cut off sheet. Shearing machine plays the role as an industrial machine that cuts metal or a machine that cuts the wool off sheep.
What are the features of shearing machine?
What is the parameter of shearing machine?
What is the development of shearing machine?
The shearing machine is all steel welding mechanism. It has a good performance in reducing vibration stress, which has good rigidity and stability.
Shearing machine adopts advanced hydraulic integrated valve block in compact structure. It can reduce pipeline connection, improving system reliability and maintainability.
The series oil cylinder makes the shear angle not change during cutting. The main oil cylinder fixed on the wallboard moves downward to control shear movement. The nitrogen cylinder controls the returning. The hydraulic system is simplified and the operation is more stable.
Shearing machine uses hydraulic transmission, which has light weight, low noise, lightness, reliability, and overload performance.
Standard shearing machine is equipped with five stations and dual hydraulic workstations, which can work independently at the same time. The shearing machine does not need any horizontal adjustment.
Shearing machine uses CNC control system to increase automatic punching and cutting efficiency.
The frame of shearing machine is welded by the whole machine. After high-temperature quenching treatment, it has high rigidity and high strength.
The major parameters in shearing machine are the shape of the punch and die, the speed of punching, lubrication, and the clearance between the punch and the die.
The clearance between the punch and the die is a major factor in determining the shape and the quality of the shearing machine. As the clearance increases, the zone of deformation becomes larger and the sheared edge becomes rougher. The sheet tends to be pulled into the clearance region. The edges of the sheared zone become rougher. Secondary operations may be required to make smoother, which will increase the production cost.
Edge quality can be improved with the increasing speed of punching of shearing machine. Sheared edges can undergo severe cold working due to the high shear strains. The hardness of the edges will reduce the ductility of the edges and adversely affect the formability of the sheet during bending and stretching.
As the high-end CNC machine tool and blade mold industrial base and a demonstration zone of the shearing machine industry, Bowang District, Ma'anshan, Anhui is established to create a national export industrial product quality and safety demonstration zone and a shearing machine industry.

Press brakes have many types, which largely depend on what you are making and the tools. It also depends on the size and type of the metal to be bend and the properties of materials. It is recommended to have a press brake that is flexible and can handle more types of materials.
How to check press brake?
How to lubricate press brake?
How to maintain press brake?
Check whether the liquid valve of the press brake mold is fully opened. If it is oil contaminated, the filling valve spool is not flexible, resulting in insufficient filling. The filling valve of the press brake needs to be cleaned and reinstalled.
Check whether the solenoid coil of the overflow valve of the press brake is energized. Whether the voltage of the solenoid coil meets the standard.
Check whether the cartridge valve or the main valve core of press brake is stuck. Whether the orifice is blocked. Disassemble the overflow valve of the press brake mold. Clean and reinstall it.
Check the oil level of the mold oil tank of the press brake to see if the oil level is too low. If the filling port is not filled with water, the upper cavity of the cylinder is filled with liquid during fast forwarding, causing insufficient filling. Add the oil in the fuel tank to more than 5mm above the filler port to make sure to submerge the filler port completely.
All the rollers and corresponding parts in the press brake must be refueled, which is three times a week.
Put butter on the upper and lower blades of press brake. Add oil three times a week. Lubricate the clutch area of the knife.
The seal coil in the cylinder of the press brake must be cleaned and lubricated at the place where the sheet metal is bent.
The oiling work of the sliding bearing and the feeding frame of the press brake needs to be carried out every three days.
When refueling the place of the feeding shaft presser plate of press brake, we need to use a grease gun to inject the oil. Clean the place where the oil is added before refueling.
If it is to refuel the connection of the brake of press brake, move it back and forth after refueling. Lubricate it three times a week and pay attention to cleaning.
An inspection of press brake will allow to notice and address small issues before they become significant problems.
Verify that the press brake is in clean condition. The table and die area should be free of mill scale.
If the press brake is tooled up or a different toolset needs to be set up, verify the punch and die alignment and inspect the condition. The punches and dies should be free of dents. Indentations and cracks show that the tool has been overstressed needed to be reconditioned or replaced.
The proper operation of press brake, including up button, e-stops, foot pedal control, and indication lights should be in good condition within few seconds.
If additional guarding is present, make sure it is set up according to specifications.
Hydraulic oil is the lifeblood of press brake. It is vital to keep the oil clean and filling the oil reservoir. Check the oil level in the tank periodically. An insufficient oil level will cause erratic operation of the ram and damage the hydraulic pump.

What are the specifications of press brake?
What is the future trend of press brake?
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.
