Press Bending

A  Press Bending (also called a press or stamping machine) is a mechanical device used for processing sheet metal. Its main function is to apply pressure to the sheet metal, causing plastic deformation between dies (upper and lower dies), thereby bending, forming, or cutting the sheet metal.

Main Components:
Frame and Worktable:Supports the entire machine structure; the lower die is mounted on the worktable.
Upper Die (Pressure Head):A liftable pressure head mounted on the main column, pressing downwards onto the sheet metal.
Hydraulic or Mechanical Drive System:Provides the force required for bending; common types include hydraulic, mechanical (gear), and servo drive.
Control System:A CNC or manual control panel used to set the bending angle, position, and stroke.
Safety Devices:Safety doors, emergency stop switches, etc., ensuring operational safety.

Working Principle:
Positioning:The sheet metal to be processed is placed on the lower die of the worktable and aligned with the center line of the upper die.
Pressure Application:The drive system moves the upper die downwards, generating high pressure, causing the sheet metal to plastically flow between the dies.
Forming: Near the stress point, the sheet metal bends to form a predetermined angle or shape.
Returning: After completion, the upper mold rises, and the formed sheet metal is removed.
