Non-indentation Bending Technology and Die Application
Bending die is the main processing equipment of sheet metal forming, with the development of engineering machinery, automobiles, ships, aerospace, electrical instrumentation and building decoration industries, the processing enterprises at home and abroad have more and more requirements for forming precision and shape complexity of sheet metal products, and the requirement for surface quality of the sheet metal parts is more and more high.
Especially the bending processing for stainless steel plate, the aluminum plate is also requiring no scratches.
In order to avoid the indentation on the workpiece surface during bending process for press brakes machine, we will analyze the causes of the surface indentation of the sheet metal parts from four aspects, which including the bending method, material hardness, concave die structure, press brake selection and die precision.
