what is a press brake machine?(The Most Detailed Guide)


A press brake machine is a machine that can bend thin metal plates. They can be equipped with different styles of punches and dies to control the degree of bending of the sheet. These machines can bend simple and complex parts and are widely used in industries such as automobiles, aeroplanes, houses and cabinets.

Working Principle

When in use, the wire is energized to the coil, and the gravitational force is generated on the pressing plate after being energized, so as to realize the clamping of the thin plate between the pressing plate and the base. Due to the electromagnetic clamping, the pressing plate can be made into a variety of workpiece requirements, and the workpiece with sidewalls can be processed. The bending machine can meet the needs of various workpieces by changing the mould of the bending machine.

Main Application

CNC press brake machines are widely used in aviation, shipbuilding, metallurgy, instrumentation, electrical appliances, stainless steel products, steel structure construction and decoration industries.

press brake machines are currently the first-choice machine for sheet metal processing, especially large-scale sheet metal processing. By matching a variety of different moulds, the sheet metal can be bent, stretched, rounded, punched, and so on.

Main Classification

Press brake machines can be divided into four types

  • Hydraulic
  • Mechanical
  • Pneumatic
  • Servo motor


Structure Description

The press brake machines machine is an important equipment for the bending and forming of workpieces in the sheet metal industry. Its function is to press the steel plate into parts of various shapes according to the process requirements.

As shown in "Structural Schematic Diagram of Hydraulic Sheet Metal Bending Machine", the frame is mainly composed of left and right columns, worktables, and beams. Left and right oil cylinders are fixed on the column, and the slider is connected with the piston of the oil cylinder and goes up and down along the guide rail fixed on the column. Movement, the lower mold is fixed on the worktable, the upper mold is installed at the lower end of the slider, the hydraulic system provides power, and the electrical system gives instructions. Under the action of the oil cylinder, the slider drives the upper mold downwards and closes the lower mold to realize the folding of the sheet. bend. The left and right columns, the workbench and the sliding block (hereinafter referred to as the three major parts) are the key parts of the bending machine. The total weight of the three major parts accounts for 70% to 80% of the total weight of a bending machine. Its strength and rigidity directly determine the operating accuracy, the service life of the machine tool, and the accuracy of the workpiece.

Features of Industrial Pressure Brakes

1. Adopt an all-steel welded structure, with sufficient strength and rigidity;

2. Hydraulic drive, the cylinders at both ends of the machine tool are placed on the sliding block to directly drive the sliding work;

3. The slider synchronization mechanism adopts a torsion shaft for forced synchronization;

4. Using mechanical block structure, stable and reliable;

5. The stroke of the slider can be adjusted quickly by motor, fine-tuned manually, and the counter is displayed;

6. Oblique wedge-type deflection compensation mechanism to ensure higher bending accuracy.



According to the ordinary hydraulic press brake machine processing metal plate to make a brief introduction:

1. First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start.

2. The stroke adjustment, the use of the bending machine must pay attention to the adjustment stroke, be sure to test run before bending. When the upper die of the bending machine descends to the bottom, there must be a gap of plate thickness. Otherwise, it will cause damage to the mold and the machine. The stroke adjustment also has electric quick adjustment and manual fine adjustment.

3. For the selection of bending notches, a notch with a width of 8 times the thickness of the plate should generally be selected. If you bend a 4mm sheet, you need to choose a slot of about 32.

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

5. Step on the footswitch to start bending. The bending machine is different from the shearing machine. You can release it at any time. When you release your foot, the bending machine will stop, and then step on to continue downward.
