First of all, the blanks are cut from steel coils on a coil line. Depending on requirements, these base sheets are edged and may be partially pre-stamped.
At several points in the process, oils and greases are used to lubricate the sheet metal for stamping and pressing operations.
Cracks in the sheet metal result if the elastic limit of the material concerned is exceeded. This is avoided using multi-stage forming. Individual presses are linked together. This chain of presses is known as the press line.
Important components of a press shop are the hydraulics, as well as the lubrication and compressed air supply to the presses and grippers. The waste generated by the pressing and stamping operations is processed in a scrap press for reuse in electric melting furnaces.
Press shops must work reliably, with very high availability of the plant components.
Here the user is supported by sensors from ifm, with their high standards of reliability and robustness.
