How many types of press brakes are there?

The structural features and working principle of the mechanical press brake are the same as those of the mechanical press. The crank connecting rod mechanism is adopted to convert the rotating motion of the motor into the reciprocating motion of the slider. The mechanical press brake has a huge structure with high cost, which is often used for bending small and medium-sized parts. The advantage of the mechanical press brake is that the sliding block is parallel to the worktable, which has high precision and can withstand eccentric loads.

The hydraulic press brake is directly driven by hydraulic pressure. The hydraulic system can apply full pressure to the metal plate. If hydraulic press brake is overload, it can protect automatically. When bending sheet metal parts, the oil in the hydraulic cushion can be squeezed out under pressure. The upper die does a little retraction movement relative to the slider.

Pneumatic press brake uses compressed air as the power source. It is generally used for bending small plates. After the pneumatic press brake adopts CNC, it can save adjustment time.

What are the types of bending in press brake? 

There are three types of bending in press brakes that are commonly used. Each requires different strategies in press brake operation.

Coining means the process of pressing coins to get the images, numbers, and lettering on a coin. The workpiece is put under the tonnage of the press brake. It requires each bend to be exactly the same. The coining method requires the largest amount of tonnage in a press brake, usually 3 to 5 times that of the other bending methods.

Bottom bending doesn’t require as much tonnage as the coining method but does require more tonnage than the air-bending method. The metal is pushed down into the V-die to make a bend. There is a slight spring back. Bottom Bending is common on mechanical press brakes.

Air Bending is the most common form of press brake forming. It requires far less tonnage. A simple die can realize multiple angles with less tooling. It is much cheaper. There is less contact with the material being formed.

How to choose press brake?

Determine the specifications and models of the press brake according to processing dimensions. In addition, you also consider the needs after the expansion of production.

After you have determined the specifications and models, you can contact the press brake manufacturer. The models produced by each manufacturer are very different. It is important to choose a proper press brake. Choose some manufacturers to compare with each other to know more about the quality, stability and after-sales service of the press brake.

The accuracy of the press brake needs to be the focus of selection. The accuracy standards of different machines have differences due to different press brakes. Some processing fields attach great importance to the processing effect of the plate.

Pay attention to the selection of molds. The loss of molds in the process of bending the plate is more serious.

What are the failures of CNC press brake?

Sometimes, there is the large or small bending angles during CNC press brake operates. It may be that the plate is uneven or the plate thickness has changed. It is also possible that the shaft in the CNC press brake is caused by deviation.

The oil pump of CNC press brake is too noisy or heats fast. Even, the oil pump is damaged. The oil pump suction line leaks or the oil tank liquid level is too low, causing to suck. The oil temperature is too low and the oil viscosity is too high, resulting in high oil absorption resistance. The oil filter at the suction port is clogged. Coupling installation is too tight to make the motor shaft and the oil pump shaft nonconcentric.

The CNC press brake system is pressure-free or cannot be built up. The oil pump rotates incorrectly. Whether the pressure gauge is damaged. Whether the pressure control valve has an electrical signal or the valve is blocked. The pressure cartridge valve is blocked or stuck that cannot seal the oil.

How to solve the large bending angle error of the CNC press brake?

With the continuous development of CNC press brake manufacturing technology, CNC press brake has the advantages of high positioning accuracy, convenience, zero-activity disturbance compensation, and good consistency of processed products.

Check whether the compensation deflection of the compensation cylinder is large so that the zero position cannot be completely restored.

Check whether the quick clamp and grating ruler is loose.

Check whether there is any change in the bottom dead center of each bending.

Check whether the bow-shaped plate is installed in a standard way and whether the screw hole is deadlocked.

The large bending angle error of CNC press brake can also be caused by changes in the sheet, such as thickness, material, and stress。

There is inaccurate positioning of CNC press brake that whether the zero offset value of the proportional valve is appropriate or not. It may be impossible to return because the positioning cannot reach the bottom dead center.

How to maintain CNC press brake?

After each shift, clean the work area of CNC press brake by removing all debris with a dry cloth. Clean the tools, bench, supports, slide guides and other accessories. Clean the backstops and guides of the backgauge. Do not use compressed air for cleaning.

The lubrication parts are sufficiently greased.

The motor and oil pump of CNC press brake operate normally without noise and overheating.

The safety protection device is safe and reliable.

Check whether the pressure of the hydraulic system is within the rated range.

The indicator is sensitive and reliable.
