How to grasp the size of bending for press brake?

The main purpose of using a press brake is to grasp the size of the bending.

Avoid using a press brake to bend the edge or large-angle alignment.

Preliminary inspection is carried out before formal processing. Cyclic inspection is carried out during the use of press brake.

In order to avoid accumulative errors, the unfolded size must be measured every time when material is added.

Choose a good processing method and a good technical preparation method to simplify the processing of press brake.

The press brake selects the appropriate machine according to the accuracy requirements of the processed products.

Do not choose tools that have decentraction. Make sure that the tip of the upper die of press brake is on the same straight line before processing.

For products whose edges must be bent by a press brake, the front bending angle must be less than 90 degrees.

Determine the accuracy of the measuring instrument before processing.

How should you use press brake?

Strictly abide by the safe operation regulations of press brake. The user must wear labor protection. Before starting, carefully check the motor, switch, circuit, grounding, and the control parts and buttons of the press brake.

Run press brake idling for 1 to 2 minutes and move on the slide 2 to 3 times at full stroke. If there is anything abnormal, stop immediately to troubleshoot the malfunction.

The sheet material must be compacted when bending to prevent hurting people during bending. The power supply must be cut off when adjusting the sheet metal die. When changing the opening of the lower mold, no material is allowed to come into contact with the lower mold. When press brake works, no one is allowed to stand behind the press brake.

It is forbidden to use press brake molds to fold over-thick iron plates or hardened steel plates.

To close the press brake, place a wooden block on the lower die under the cylinders on both sides and lower the upper slide plate onto the wooden block.

How to adjust the bending angle of press brake?

Before using the press brake to bend the material, you need to adjust its various angles, including the bending force, the distance of the back gauge, the upper limit of the slider, the speed of the slider, and the adjustment of the upper and lower mold gaps.

The adjustment of the angle of the press brake is mainly to calculate the value of the bending force and indicated pressure according to the calculation formula. Then, adjust the handwheel of the overflow valve to generate the force which is slightly larger than the force of the folded plate.

The adjustment of the backgauge distance of the press brake needs to position in the length direction when bending the sheet. The button on the front button box controls the motor adjustment, whose value can be from the revolution table on the button box. There is a handwheel for fine adjustment.

The adjustment of the upper limit of the slider of the press brake needs to be realized by adjusting the position of the striker. The rising slider can stay at the required center position, which can shorten the stroke distance of the slider. It reduces the working cycle time and increases productivity.

The adjustment of the gap between the upper and lower molds in the press brake is completed by the button on the button box. Operate in the direction indicated by the press brake label. The initial adjustment gap should be greater than the thickness of the plate.

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.

How does CO₂ laser cutting machine work?

In aCO₂ laser cutting machine, light is produced when electricity runs through a gas-filled tube with mirrors at both ends. The discharge tube of the CO₂ laser cutting machine is filled with mixed gases such as CO₂, N₂, and He.

There are three different forms of motion for any molecule. One is the movement of electrons in the molecule, which determines the electronic energy state. The second is the atoms vibrate periodically around their equilibrium position, which determines the vibrational energy of the molecule. The third is the rotation of the molecule, which determines the rotational energy state of the molecule.

The CO₂ laser cutting machine uses the transition between the vibration and the rotation energy level of the CO₂ molecule to generate laser light.

What are the advantages of CO₂ laser cutting machine?

l The CO₂ laser cutting machine doesn’t physically touch the material it is working with. Instead, it causes the material to melt through intense heat, causing minimal damage to the material and the machine.
