Definitions

  • a punching device consisting of two punching units and a bending device are provided for the processing of metal sheets.
  • the two punching units of the punching device are movable in opposite directions along the bending line defined on the bending device.
  • conveyor belts run by belt conveyors, by means of which workpieces to be machined and machined workpieces are removed. In the transverse direction of the bending line moves a workpiece manipulator.
  • a sheet to be processed is first transferred to the prior art arrangement of the respective belt conveyor along the bending line of the bending device in a position from which a feed cylinder moves the sheet in the transverse direction of the bending line to the punching device.
  • the punching units of the punching device and the sheet are then under Method of punching units along the bending line adjusted relative to each other.
  • the sheet is received by the workpiece manipulator and transferred in the transverse direction of the bending line relative to the punching units of the punching tools in at least one processing position for punching or cutting processing.
  • the workpiece manipulator moves with the sheet toward the bending device, on which the bending workpiece machining is then performed.
  • the cutting device is coupled to the workpiece support of the transverse guide for movement in the second axial direction.
  • workpiece movements as well as for cutting workpiece machining in the second axis to be performed relative movements of cutting device and workpieces are thus realized by means of a single drive.
  • only one single drive also requires the execution of the relative movements of workpieces and cutting device required along the machining line. Notwithstanding it by minimizing the number of needed Drive axes conditional simple structural design of the inventive arrangements are highly flexible to changing application requirements or user needs customizable.
  • the assembly optionally with one or two drive axles or machining devices.
  • an arrangement that is bestimmmt only for bending workpiece machining and has only a bending device and a handling of the workpieces to be machined and the bending parts serving transverse guide can be supplemented with little effort to the additional function "cutting workpiece machining".
  • only a cutting device and, if necessary, a longitudinal guide are provided in addition to the already existing components.
  • a provided with a cutting and a bending device as well as with a longitudinal and a transverse guide arrangement can be designed in a simple manner for exclusively bending workpiece machining. It is then only to dispense with the blocks “cutting device” and “longitudinal guide”. Function-related redundancies on the "dismantled" arrangement are avoided.
  • the claims 2 and 3 relate to invention types with processing devices that allow a particularly expedient and practice-oriented implementation of the inventive concept.
  • a cutting device for example a guillotine cutter, is conceivable in particular.
  • a workpiece by means of the workpiece storage of the transverse guide not only in the second axial direction but also to move about an axis of rotation extending in the transverse direction of the workpiece main plane.
  • This movement possibility can be used on the one hand to position the relevant workpiece with different rotational positions relative to the second processing device.
  • an example of the processing serving workpiece rotation is conceivable relative to the motion-coupled with the workpiece support of the transverse guide cutting device.
  • a machine assembly 1 is used for processing metal sheets 2.

  • the cutting device 3 is supported on the upper leg of the support frame 12 in the vertical direction 8 deliverable.
  • a workpiece holder 13 serving as a workpiece support. It is formed in two parts and has a holder top 14 shown in FIG Leg of the support frame 12 and a recognizable in Figure 2 Halterunterteil 15 on the lower leg of the support frame 12.
  • the upper bracket 14 has a movable in the vertical direction 8 piston rod 16 which is provided at its free end with a contact plate 17.
  • the lower holder part 15 comprises a piston rod 18, which can be moved in the vertical direction 8, with a contact plate 19.
  • the support frame 12 and the workpiece holder 13 are parts of a transverse guide 20, which also includes a highly detailed in the figures reproduced motor rack drive 21.
  • the rack and pinion drive 21 By means of the rack and pinion drive 21, the support frame 12 and with this the workpiece holder 13 and the cutting device 3 in an axial direction illustrated by a double arrow 22 are movable.
  • the axial direction 22 extends perpendicular to a bending or processing line 23 defined on the bending tool 7 of the bending device 4 and indicated by dash-dot lines in FIG.
  • a longitudinal guide 25 is effective in the longitudinal direction of the processing line 23, ie in an illustrated in Figure 1 by a double arrow axis 24, a longitudinal guide 25 is effective.
  • the longitudinal guide 25 comprises a cross member 26 with two clamping claws 27 as workpiece storage.
