What are the advantages of CNC press brake?

The main cylinders on both sides of the CNC press brake synchronously adopt a hydraulic control system and a grating ruler to form a closed-loop control, which is independently restricted by CNC. Accurate feedback data ensures safe operation of the slider.

The CNC press brake has high strength and good rigidity. It is stable and reliable with high precision. Backgauge distance and slider stroke adopt electric and manual fine adjustment. CNC press brake is equipped with a digital display device, which is convenient and quick to use.

The CNC press brake has a multi-step programming function, which can realize automatic operation, continuous positioning, and automatic and precise adjustment. The processing of CNC press brake shows real-time display and can remember the position and parameters after power failure.

The backgauge adopts imported ball screw and linear guide to ensure the positioning accuracy.

The CNC press brake uses a servo motor as an actuator. When the bending operation is not performed, the motor does not move and consume power. 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.

What is the proper CNC press brake setup procedures?

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.

It’s time to run CNC press brake.

What are the uses of CNC press brake?

Medical fields are assisted by CNC press brakes in the manufacturing and production of high-tech and crucial equipment, such as X-ray machines, components to emergency vehicles, and the actual construction of hospitals.

Military and defense industries employ CNC press brakes to design and craft components to weapons, vehicles, and other significant equipment. The military industry is one of the most invested by the advanced machines. The usage of CNC press brake speeds up the processes of building and testing new equipment.

The usage and importance of CNC press brakes cannot be understated. Without these machines, precise crafting would not be as widely possible and instituted as it is today. The CNC machine industry has always been at the forefront of innovative design to expand further outside industries.

What is the difference between CNC press brake and electro-hydraulic press brake?

The CNC press brake uses a torsion axis to link the left and right swing rods to form a torsion axis, forcing a synchronization mechanism to move up and down the cylinders on both sides. It is a mechanical forced synchronization method. The parallelism of the slider cannot be automatically checked and adjusted.

The electro-hydraulic press brake installs a magnetic scale on the slider and the wall plate. The numerical control system can analyze the synchronization of the two sides of the slide through the information feedback from the magnetic scale at any time. If something wrong, the numerical control system will be adjusted by a proportional electro-hydraulic servo valve to synchronize the strokes on both sides of the slider. They constitute the feedback closed-loop control of the electro-hydraulic press brake.

The parallelism of the slide block determines the angle of the workpiece. The CNC press brake keeps the slide block synchronized by the machine. There is no real-time error feedback. However, its eccentric load capacity is poor.

The electro-hydraulic press brake is the system through the proportional electro-hydraulic valve group to control the slider synchronization. The magnetic scale reports real-time error.

The CNC press brake does not have a control system and V-axis compensation. You can only stake out and do trial bending first.

The electro-hydraulic press brake is controlled by a professional numerical control system with V-axis compensation. There is a simulated bending function that no stakeout is required.

How to choose a suitable CNC press brake?

When purchasing CNC press brake, consider the production of parts. It must be able to complete the processing tasks. The workbench must be the shortest and the tonnage can be the smallest. The material grade and the maximum processing thickness and length should be paid attention to.

The shorter workbench, the fewer shim adjustments to produce qualified parts. Reduced shim adjustment shortens preparation time.

When free bending is used in CNC press brake, the bending radius is 0.156 times 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 of CNC press brake is almost as small as the material thickness, a bottomed die must be formed.

In order to choose the lowest tonnage specification, it is best to plan for a bending radius larger than the thickness of the material, using the free bending method.

The accuracy is the most important factor affecting your choice. It determines whether you need to consider a CNC or a manual press brake. If the bending accuracy requires within 1° and cannot be changed, you must focus on the CNC press brake.

How to improve the lifespan of CNC press brake?

Create a uniformly distributed machining allowance for each type of bending in each bending process. The main CNC press brake mold should be as close as possible to the final shape of the mold in each process.

The evenly distributed machining allowance of the CNC press brake mold ensures a constant and high productivity and a safe bending process. When the angle is constant, the bending speed and feed rate can also be kept constant at a high level.

Continuous cutting of CNC press brake should be maintained for as long as possible during the bending process. Otherwise, it will increase the thermal stress and thermal fatigue on the cutting edge. A uniform and high temperature in the cutting area is more beneficial.

Why we use press brake?

Press brake uses the electro-hydraulic servo system to control the two-cylinder synchronization. Press brake cooperates with the international standard grating ruler to form a fully closed-loop control. The synchronization has high accuracy and high level of the bending and repeat accuracy.

Press brake can be equipped with hydraulic upper mold automatic clamp, quick clamp, or slot type lower mold to reduce the labor and improve efficiency.

Press brake is equipped with high-quality linear guides and ball screws to ensure the accuracy.

Press brake has flexible operation mode, not only solving the processing of ultra-long plates by dual-machine linkage, but also processing short parts by single-machine operation. Press brake improves the utilization rate and reduces energy consumption.

The frame of press brake is welded with steel, ensuring high rigidity and machining accuracy.

How does press brake work?

To avoid cracks on the radius, it is essential that the press brake is carried out orthogonally to the rolling direction.

The press brakes are controlled by mechanical systems, a crank connecting rod system, and hydraulic pistons. Press brake can be operated by manually or computer, called CNC press brake.

The metal sheet is deformed by a bending force of press brake which necessarily exceeds the limit that the elasticity of the material imposes.

Also, the press brakes are equipped with a punch mounted on the movable part. This part of press brake is composed of a die and a blank holder piston with the same functions and characteristics of a mold for a press.

Press brakes contain a work table, a clamping plate, and supporters. The worktable consists of a base and a pressure plate, which is attached to the supporters. As working with a press brake, adjust the bending angle and dimensions continually.

What are the uses of press brake?

The forming of press brake greatly depends on operator’s skill. Therefore, varying levels of quality and productivity are to be achieved by two different operators.

Press brake is available for bending sheet metal. The sheet metal will play a important role in the manufacturing industry. These sheet metals processed by press brake are used in home appliances, vehicles, heavy equipment.

Before the right sheet metals are formed, press brakes should first consider the right die design to produce the right sheet metal. Press brakes are used in different forming works with the right die design like V dies, rotary bending dies, acute angle dies, and radius dies.

In a mechanical press brake, power is added to a flywheel with an electric motor. A clutch matches the flywheel to power a crank mechanism moving vertically. Accuracy and speed are two advantages of the mechanical press brake. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam.
