  • the carriage is moved from outside the punch press under the plunger, whereby long travels of the carriage are to be mastered.
  • long travels is accompanied by the fact that the carriage and a guide of the carriage have some extra-long parts that can deform and / or move and thus can lead to imprecise movements of the carriage especially at high stroke rates.
  • the space requirement of such an arrangement is particularly high because the drive and guide mechanism for the carriage is to be arranged next to the punch press.
  • the plunger has to cope with the previous punching press long travels so that it has to achieve very high speeds at high speeds.
  • the associated also high accelerations of both the plunger and the carriage reduce the transport and punching security and increase the wear of the parts associated with these movements.
  • high speeds of the affected parts, ie the tappet and the carriage, also imply high inaccuracy in the position and timing of punching or ejecting a stamped sheet.
  • sheets for a stator and for a rotor are often punched out of the same sheet blank or the same section of the sheet metal strip. Conveniently, it will be directly two sheet metal parts in produced a punching process. In this case, it is particularly complicated to bring the punched sheet metal parts on the carriage for conveying. In such a method, the metal strip or the sheet metal blank can not be nachgeschoben as long as one of the punching plates is under the plunger. This fact prevents a high processing speed and efficiency of the punch press because the punched sheet blocks the operation of the punch press until it is conveyed out of a corresponding slide.

As a result, inaccurate drops and possibly even damage to the sheet can be largely avoided.
  • Moving horizontally and vertically below the bumping means that the receptacle can be moved horizontally and vertically in an area that is located below the plunger at the horizontal position of the bite ice.
