Definitions

  • This invention relates to a punching machine for sheet metal strip.
  • Punching machines in metal strip processing lines are known. They generally comprise punching heads, the tools (punches) of which are driven, in accordance with the predetermined operative cycle, by hydraulic cylinders applied to the head itself and acting on the metal strip to be processed, which advances between said punches and the respective dies.
  • the strip is advanced by a feed device controlled by a central control unit, as are the punch operating cylinders.
  • the punch heads consist essentially of a thick metal plate which is disposed vertically and cut to ring shape to display a horizontal slot for passage of the strip to be processed.
  • the punches and the respective operating cylinders are applied to one or both the sides of the upper part of this ring-shaped plate, the dies being applied to the lower part.
  • a drawback of these heads is a substantial cost due to the operating cylinders, the number of which corresponds to the number of punches used, as stated.
  • heads comprising a loader for a plurality of punches positioned below a single cylinder provided with a piston rod with a rotary selector.
  • An object of the invention is to eliminate this drawback by providing a punching machine having high versatility while using only a small number of processing means.
  • the punching machine comprises substantially a bed 2 for a carriage 4 provided with slide blocks 6 for its sliding along guides 8 disposed transversely to the bed.
  • the carriage also presents a horizontal slot 18 faced by two C-shaped thick vertical metal plates 20, 20', with their cavities facing each other.
  • Each plate 20, 20' is rigid with a horizontal plate 22 rigid with the piston rod 24 of a hydraulic cylinder-piston unit 26 mounted on the carriage.
  • each vertical plate 20' there is applied a loader 28 carrying punches 30 which are faced by corresponding dies 32 provided on the lower side of the plate.
  • the piston rod 34 of a rotary selector cylinder 36 rigid with the carriage acts selectively on the heads of said punches.
  • a control unit (not shown in the drawing) for controlling the advancement and movement of the strip, of the carriage 2 and of the plates 20, 20' and for controlling the operation of the cylinder 36 is associated with the machine.
  • the punching machine operates in the following manner:
