CNC double-V die press brake- Factory Suppliers Manufacturers From China

The CNC press brake is composed of a bracket, a workbench and a clamping plate. The gravitational force is generated by energizing the coil to the pressure plate, completing the support for the thin plate between the pressure plate and the base. Because of the electromagnetic clamping method, CNC press brake can bend the plate according to the specific requirements.

What is the structure of CNC press brake?

CNC press brake adopts hydraulic transmission and mechanical block. The cylinder is fixed on CNC press brake, while the piston rod is fixedly moved by hydraulic pressure. The mechanical block is used that the adjustment value is controlled by the environmental protection system.

Workbench of CNC press brake is designed by a button box. The retained intercepting material rack moves forward, whose distance is controlled by the control system. The minimum valve is about 0.01mm, which is limited by switch positioning of the front and rear position.

CNC press brake consists of a mechanical synchronization mechanism, which is composed of torsion shaft, swing arm, and joint motion. CNC press brake has simple structure, stable and reliable performance, and high synchronization accuracy. The mechanical stop is controlled by the motor to control the value of the system.

Material stopper mechanism used in CNC press brake is driven by a motor. The two screw rods move synchronously through chain operation.

What materials can be bent by CNC press brake?

The most commonly used carbon tool steels in CNC press brake are T8A and T10A. They are good at processing at low price. However, the harden ability and red hardness are poor. The heat treatment deformation is large with low bearing capacity.

As another common materials used in CNC press brake, low-alloy tool steel is based on carbon tool steel with an appropriate amount of alloying elements. It reduces the tendency of quenching deformation and cracking, improving the harden ability of steel. It has better wear resistance.

High carbon and high chromium tool steel

High carbon and high chromium tool steels are another important material used in CNC press brake. They have good harden ability and high wear resistance. The heat treatment deformation is very small. CNC press brake die steel is second only to high-speed steel in carrying capacity. However, the segregation of carbides is serious, which has to upset and forge again to reduce the unevenness of carbides.

What affects the deflection of CNC press brake?

Two working cylinders of CNC press brake are pressurized at both ends of the slider. The resultant force of the deformation of the workpiece is in the middle, so the worktable of the sliding block of CNC press brake will be flexed and deformed together with the upper and lower molds.

The sheet material will receive uneven force at various points along the length of the die edge, which directly affects the accuracy and straightness of the bent workpiece. To make up for this shortcoming of CNC press brake, a deflection compensation device can be installed.

Preset a deformation amount opposite to the force deformation direction between the press brake slider and the upper die. The amount of deformation is the same as the relative amount of deformation during actual work. The relative deformation of the slider and the worktable is compensated so that the pressure distribution between the dies is more uniform. CNC press brake improves the quality of sheet metal bending.

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.

When repairing after the end of production, the slider needs to be lowered to the lowest point.

Check whether the fixed part of the mold is loose before work.

When working, the CNC press brake must not exceed the maximum pressure that is 160KN.

How about the speed and power of laser cutting machine?

The power of the laser cutting machine is usually above 7W. It is determined according to the material, thickness and processing effect. FPC cutting usually uses 10W, 12W or 15W machines, while PCB cutting adopts 18W or 20W one.

The processing speed of the laser cutting machine is directly related to the material, thickness, and power. The higher the power, the higher the processing speed. The thinner the material thickness, the higher the processing speed. The higher the material absorbs laser beam, the higher the processing speed. The processing speed of PI film is much higher than the processing speed of thin metal.

The laser cutting machine is better to process thin materials, while the processing efficiency will be lower for other materials. The laser cutting machine can process thicker materials such as PCB, carbon fiber, and metal material. PCB can be processed with no more than 2mm, carbon fiber no more than 1mm, and metal material no more than 0.2mm.

Ventilation dust collector extracts the smoke and dust to carry out filtering treatment. Air cooling dryer and filter are used to supply clean and dry air.

 

Is laser cutting machine popular?

Of course! Laser cutting machine has been widely used everywhere. Due to the small laser spot, high-energy-density and fast cutting speed, it can perform better cutting quality, especially for small and exquisite products.

Laser cutting machine has higher electrical efficiency. Conventional machine requires more energy to produce the laser beam. In fact, a 2kW laser cutting machine uses a third of the power as a 4kW traditional machine. The fiber optic configuration will save power, but increases the lifespan due to the lower energy requirements.

Laser cutting machine allows for highly accurate cuts that leave a clean cut and a smooth finish. It does not need to contact the workpiece. And the heat-affected area is small. This minimizes the damage to the material surface.
