Preparation of sheet metal: Before it goes to the press, the sheet metal must be properly cut to the desired size. It is also worth taking into account the sheet material (e.g. steel, aluminum, copper), because different materials have different plastic properties and may require different settings of the press parameters.
-
Tool Selection: A press brake relies on two key tools: a die (the lower part, which is stationary) and a punch (the upper part, which presses against the sheet metal). Depending on the shape we want to obtain, appropriate dies and punches are selected, which determine the bending angle and radius.
-
Setting press parameters: The selection of appropriate press operating parameters, such as pressure force, bending speed and setting appropriate tool angles, is crucial. Too little pressure may result in insufficient deformation of the sheet metal, while too much pressure may result in cracking or deformation.
-
Bending process: The sheet metal is placed on the die, and then the punch presses on it with appropriate force, causing it to deform at the point of contact. This process is carried out in a controlled manner, which allows obtaining precise angles and shapes.
-
Inspection and correction: After bending, the product is checked for compliance with design requirements. If there are any deviations, it is possible to correct the press settings and bend again. The bending process on a press brake is repeatable, which allows precise and mass bending of elements.
