Electro-Hydraulic CNC Press Brake with DA-66T CNC System From China Supplier.
A press brake is a machine tool used in metalworking and metal fabrication for bending, shaping, and forming sheet metal and plate materials. It is an essential piece of equipment in industries such as manufacturing, construction, automotive, aerospace, and more. Here are the key components and functions of a press brake:
Frame: The frame of the press brake provides the structure and rigidity necessary to withstand the immense forces generated during the bending process. It is typically made of heavy-duty steel to ensure stability.
Bed and Ram: The bed is the flat, horizontal surface where the sheet metal or plate material is placed for bending. The ram, also known as the upper beam, moves vertically and exerts downward force to bend the material against the bed. The ram is usually controlled hydraulically or mechanically.
Die and Punch: The die is a stationary tool mounted on the bed, while the punch is attached to the ram. Together, they create the desired shape or bend in the material. The punch and die have complementary profiles that determine the final bend angle and shape.
Back Gauge: A back gauge is a mechanism that helps position the sheet metal accurately before bending. It ensures that bends are made at precise locations and angles, which is crucial for maintaining the desired part dimensions.
Hydraulic or Mechanical System: Press brakes can be operated using hydraulic or mechanical systems. Hydraulic press brakes use hydraulic cylinders to control the movement of the ram, offering precise control and flexibility. Mechanical press brakes use mechanical linkages and leverage for bending, making them suitable for simpler bending operations.
CNC Control: Many modern press brakes are equipped with Computer Numerical Control (CNC) systems. CNC press brakes allow for precise and programmable control of the bending process, including adjusting bend angles, back gauge positions, and sequencing multiple bends for complex parts.
Safety Features: Press brakes are equipped with various safety features, including two-handed controls, light curtains, and interlocks to protect operators from potential hazards during operation.
Tooling: Press brakes use a variety of tooling options, including different types of punches and dies, to create various bend shapes and sizes. The choice of tooling depends on the specific requirements of the job.
Press brakes are versatile machines used to create a wide range of products, from simple brackets and enclosures to complex aerospace components and automotive parts. Their ability to accurately and consistently bend metal materials makes them essential in modern metal fabrication processes.
