| 摘要 |
The invention relates to a production device for carrying out a forming process on a sheet-metal workpiece, comprising a press table and a press crosshead (11), which is adjustable by means of a drive device in relation to the press table in a direction directed perpendicularly to a longitudinal extent of the press crosshead (11), wherein the drive device comprises at least three drive units, which are arranged distributed over the longitudinal extent of the press crosshead (11). The production device comprises a measuring device (18) for measuring the momentary position of individual points on the press crosshead (11) and a control device for adapting a deformation of the press crosshead (11), wherein the measuring device (18) comprises a laser transmitter (21) for generating a laser beam (23) aligned in the longitudinal extent of the press crosshead (11). |
