What is Sheet Metal Bending Machine?

The CNC bending machine is a machine tool that utilizes hydraulic, electrical, and other technical means to bend metal sheets into shaped components. Its primary purpose is to process metal sheets into various precise components and parts through bending. Its features include easy operation, high processing efficiency, high precision, and strong reliability, making it widely used in the field of metal processing.

How Does CNC Bending Machine Works?

The CNC sheet metal bending machine, controlled by a computer system, allows users to input parameters such as the size of the sheet metal and the bending angle. The computer then controls the bending mechanism to carry out the bending process, reducing the difficulty of manual operation and ensuring stable processing precision.

Typically, the metal sheet is first placed on the worktable and secured in position using fixtures or positioning devices. Force is then applied to the metal sheet by upper and lower dies to induce bending. The gap between the upper and lower dies determines the bending angle and radius of the metal sheet.

What are the Parts of the Bending Machine?

The automatic sheet metal bending machine is a crucial equipment for processing metal sheets, consisting primarily of the body, worktable, dies, hydraulic system, and electrical system.

  • Body: Constructed from high-strength steel plates welded together, providing excellent stability and rigidity, serving as the primary support structure for the bending machine.
  • Worktable: Supports the metal sheets during processing, typically equipped with feeding devices and fixtures to ensure accurate positioning and stability of the sheets during bending.
  • Dies: The critical components responsible for bending the metal sheets, comprising the upper and lower dies. The upper die is mounted on the mechanical arm, while the lower die is fixed to the body. Both are often made of high-hardness materials to ensure precision and stability during bending.
  • Hydraulic System: Acts as the power source for the bending machine, driving the up-and-down movement of the mechanical arm through hydraulic oil, applying force to achieve the bending of metal sheets. The design and performance of the hydraulic system directly affect the efficiency and processing quality of the bending machine.
  • Electrical System: Controls the operation and parameter settings of the bending machine, including control panels, sensors, etc., used to monitor and adjust various parameters during bending to ensure processing accuracy and stability.

These components work together to form the overall structure of the bending machine, enabling precise bending of metal sheets.

The CNC panel bending machine utilizes numerical control technology to achieve the bending forming of metal sheets. Equipped with dies, it can bend cold metal sheets into various geometric shapes of workpieces. It is widely used in industries such as metal processing, automotive manufacturing, shipbuilding, aerospace, and is suitable for processing various metal sheets and structural components.
