How to perform CNC press brake?

Close the rear protective door of the CNC press brake. Turn on the power. Turn on the switch on the control panel of CNC press brake. Then, start the oil pump. The CNC press brake does not operate at this time. Release all emergency stop switches.

Adjust stroke. Pay attention to adjusting the stroke when using it. You must test it before bending. There must be a gap of plate thickness when its upper die descends to the bottom. Otherwise, it will cause damage to the CNC press brake. The adjustment of the stroke also has electric quick adjustment.

For the selection of bending notches for CNC press brake, a notch with a width of 8 times the thickness of the plate should generally be selected.

Backgauge adjustment generally has electric quick adjustment and manual fine adjustment, which is the same as the shearing machine.

Press down the blue "reset" button on the pedal and the "reset rearguard" button on the electric box, ensuring that the two blue reset indicator lights are off.

Turn the function forwarding switch to the "auto" position and press the motor start button after the controller self-test is over.

The CNC press brake finds the reference point and loads the corresponding bending program. Ensure that the mold installed in the CNC press brake is consistent with the programmed mold. Ensure that the sheet material is consistent with the programming page.

How to adjust the gap between blades of CNC press brake?

Remove the lower blade of CNC press brake and clean it piece by piece. Select one side to install tightly. Check the straightness of the blade in the horizontal and vertical directions.

Remove the upper blade of CNC press brake and clean it piece by piece. Then, the operation is same with that of the lower blade.

The upper blade is fixed. We adjust the blade gap by adjusting the lower blade.

The left and right screws of the lower blade increase the clearance. Loosen the four bolts on the table of the lower blade.

Manually turn the upper blade down to the proper position. The operator adjusts at the blanking area of the CNC press brake.

Use a feeler gauge to roughly adjust to 0.5mm from the unoccupied part of the upper and lower blades.

Manually turn the blade to the middle position and adjust it to 0.5mm.

Manually turn the blade up to the right position where the upper and lower blades are not disengaged. The middle position is roughly adjusted to 0.5mm.

Manually turn the upper blade to the proper position and start fine adjustment.

What should be considered when using CNC press brake?

Before working, you must check the surrounding area of CNC press brake for any objects that may cause harm to it. Make sure the surroundings are clean, especially backgauge. Check the position of the oil mark in the oil tank. Check the hydraulic part for leaks.

The CNC press brake should be operated by professors. The operators must wear the corresponding labor protection supplies.

After turning on the power switch of the CNC press brake, do not start the oil pump immediately. Start the oil pump only after the computer screen displays normal.

After starting the CNC press brake, run it for 2 to 3 minutes without anything. Run the slide block at full stroke for 2 to 3 times. Check the motor and CNC press brake for noise. If the temperature is low, the oil tank and oil circuit must be preheated.

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?

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.

What is the structure of shearing machine?

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.

How does shearing machine work?

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.
