Definitions

  • the invention relates to a method for obtaining at least two workpiece cutouts from a plate-like workpiece, in particular at least two sheet metal cutouts from a sheet, wherein by preparative cutting with moving workpiece, the connection between the workpiece cutouts and the remainder workpiece by means of a cutting device partially, ie, leaving a residual connection , is cut free, wherein after the preliminary cutting by final cutting on the stationary workpiece, the remaining connection of the workpiece cutouts with the remaining workpiece by means of a cutting device along at least one cut line is cut and the workpiece cutouts are removed after the final cutting of the remaining workpiece.
  • Such a method for obtaining sheet metal cutouts from a sheet is in DE-C-38 32 215 described.
  • a plurality of separating cuts are made on a metal sheet by means of a punching or nibbling device.
  • the sheet in question is moved by means of a sheet metal handling device relative to the punching or Nibbelvorraum. Due to the separating cuts the connection between several sheet metal cutouts and a remaining workpiece is partially severed. Each of the partially cut-sheet metal cutouts is connected to the remainder of the work piece via a separate remainder connection that exclusively exists for this sheet metal cutout.
  • the sheet is fed to a sheet metal shears.
  • the maximum cutting length of the sheet metal shears corresponds at least to the length or the width of the sheet to be processed.
  • the sheet metal scissors created on the stationary sheet a final separation cut, which extends over the entire width or length of the sheet.
  • several sheet metal cutouts connected along the cutting line of the final separating cut to the remainder of the work piece are completely separated from the remainder of the work piece. Subsequently, the cut-out metal cutouts slide onto a conveyor belt for removal.
  • this object is achieved by the method according to claim 1. Accordingly, the connection between the workpiece cutouts and the remaining workpiece in the direction of the cutting line (s) of the final cutting cutting is already shortened by the preliminary cutting. This shortening is dimensioned such that the remaining remnant connection between the workpiece cutouts and the remainder workpiece lies in the processing area of the cutter for the final cutting cut. In this way it is according to the invention It is also possible to machine workpieces which are larger than the working area of the cutting device for the final cutting. As a result, the method according to the invention can be carried out in particular with conventional machine tools whose cutting devices used for the final separating sheath have a machining area which is smaller than the workpiece to be machined.
  • the residual joint between the workpiece cut-outs and the remainder workpiece is simultaneously cut by the final cut-cutting along the entire cut line (s).
  • a simultaneous free cutting takes place in the case of a punching free cutting by means of a single punching stroke of a punch. In this way it is avoided that an already cut workpiece cut-out slips during the free cutting of a further workpiece cutout in the stationary remainder workpiece. For a process-safe removal of the cut-cut workpiece cutouts is ensured.
  • the completely cut workpiece cutouts are removed by gravity from the remainder of the workpiece. Accordingly, the workpiece cutouts fall or slip in the discharge direction. The need for handling the workpiece cutouts by means of complex handling devices is eliminated.
  • the preliminary separation cutting and the final separation cutting are performed by means of one and the same cutter. In particular, therefore, eliminates an additional transfer of the workpiece between the preparatory and the final cutting.
  • the device for carrying out the method can u. U. get along with a single cutter.
  • the remaining connection between the workpiece cutouts and the remaining workpiece is cut free by the final cutting along cutting lines according to claim 6, which are not arranged in mutual rectilinear extension to each other. Since cuts running in different directions can be made, the workpiece cut-outs to be cut together can be flexibly arranged with respect to each other.
  • the workpiece cutouts are arranged at the final cutting across an opening of a workpiece table supporting the workpiece. A fast and reliable removal of the workpiece cutouts is made possible.
  • a further measure for ensuring a high process reliability of the method according to the invention results from claim 8. Accordingly, the connection between the workpiece cutouts and the remaining workpiece is cut free by the preparatory cutting such that the workpiece cutouts remain surrounded by the remainder of the workpiece.
  • the remaining workpiece thus encloses the workpiece cutouts like a frame.
  • Frame-like remnant workpieces have an increased Stability against unwanted deformations. Such deformations can lead to collisions between the remaining workpiece and machine parts. Due to the increased stability of the residual workpiece such collisions are avoided and process-reliable workpiece machining is ensured.
  • the claims 9 and 10 relate to measures by which the time required for the final cutting and the removal of the cut-cut workpiece cutouts is reduced.
  • the residual compound according to the invention between the workpiece cutouts and the remainder of the workpiece is formed by a common connecting web.
  • the common connecting web By free cutting of the common connecting web, the workpiece cutouts are simultaneously completely cut free from the remainder of the workpiece. The thus cut workpiece cutouts are simultaneously removed from the remainder of the workpiece according to claim 10.
  • FIGS. 1a to 1d is a plate-like workpiece in the form of a sheet 1 in the extraction of two workpiece cutouts, in particular of two sheet metal cutouts 2 shown.
  • a machine tool as in FIG. 3 shown and as described in detail below.
  • FIG. 1a shows the sheet 1 during the preparatory cutting.
  • the preparatory cutting takes place with moving sheet metal.
  • the two sheet metal cutouts 2, which in each case have three smaller punched holes, are still connected to the remaining workpiece 3 by a residual connection 4 at the time shown.
  • a cutting device of the used machine tool has a processing area 5.
  • the sheet metal cutouts 2 have been separated from the sheet 1 by separating cuts 6 made by the cutting device.
  • the remaining compound 4 between the two sheet metal sections 2 and the remaining workpiece 3 in the direction of aligned, ie rectilinearly extending cutting lines 7 is according to FIG. 1a larger than the processing area 5 of the cutting device. Consequently, the residual compound 4 can not be completely separated from the remainder of the workpiece 3 when the metal sheet 1 is stationary.
  • the sheet metal 1 is moved or repositioned relative to the cutting device such that the sheet metal area to be processed enters the processing area 5 of the cutting device.
  • the residual compound 4 is shortened between the sheet metal cutouts 2 and the remaining workpiece 3 in the direction of the cutting lines 7.
  • the sheet metal areas to be processed are brought into the processing area 5 of the cutting device while moving the sheet 1 relative to the cutting device.
  • the separating cuts 6 are lengthened in the direction of the cutting lines 7.
  • FIG. 1b the sheet 1 is shown after the preliminary cutting and immediately before the final cutting.
  • the sheet metal cutouts 2 are still connected to the surrounding frame-like remaining workpiece 3.
  • the remaining compound 4 is now in the processing area 5 of the cutting device.
  • the following final cutting of the sheet metal cutouts 2 is carried out along the cutting lines 7 with resting sheet 1.
  • Figure 1c shows the sheet 1 with completely of the frame-like remnant workpiece 3 cut-sheet metal sections 2. Based on the situation according to Figure 1c the cut-sheet metal cutouts 2 are simultaneously removed from the frame-like residual workpiece 3. In Figure 1d the remainder of the workpiece 3 is shown after removal of the sheet metal cutouts 2.
  • the sheet metal cutouts 2 are cut free by the final cutting without intermediate movement of the sheet 1 of the remainder of the workpiece 3 and at the same time with unchanged position of the sheet 1 or remainder workpiece 3 discharged. Due to the joint production of two sheet metal sections 2, the production time per sheet metal section 2 is shortened compared to a single part production. The final free cutting and removal of the sheet metal cutouts 2 takes place at rest Sheet 1, in order to avoid undesired slipping of the completely cut-sheet metal cutouts 2 relative to the residual workpiece 3.
  • Sheet metal cutouts 12 have been cut free during preparatory cutting in such a way from the remainder of the work piece 11 that they remain connected to the remainder of the work piece 11 via a common connecting web 13.
  • the joint connecting web 13 of the sheet metal cutouts 12 is cut free with the remaining workpiece 11 by means of the cutting device along the cutting lines 14.
  • the cutting lines 14 are arranged in this case parallel to each other.
  • sheet metal cutouts with other contours can also be cut free. This is exemplified by circular sheet metal cutouts 15. Cut lines 16, along which the circular sheet metal cutouts 15 are cut free by the final cutting cut, have a curved course and consequently run in different directions. The same applies to cutting lines 17 of sheet metal cutouts 18th
  • Sheet metal cutouts 19 it can be seen how four sheet metal cutouts are to be cut free by preparatory cutting, so that they can be finally cut free when the sheet 10 is stationary.
  • Sheet metal cutouts 20 can each pair completely from the remaining work piece 11 are cut free, wherein between the final cutting edge of a pair and another pair, the sheet 10 must be moved linearly relative to the cutter only in its transverse direction.
  • Sheet metal cutouts 12, 15, 18, 19 and 20 which are shown by way of example, each have an identical shape in each case cut together sheet metal cutouts. In principle, however, it is also possible to cut open cut-outs of different shapes together.
  • FIG. 3 shows the trained as a laser punch press 30 machine tool on which the above method for obtaining sheet metal cutouts is carried out of a metal sheet.
  • the laser punch press 30 has a conventional punching device 31 and a conventional laser cutting device 32 as cutting devices.
  • a sheet metal 33 to be processed is supported on a workpiece table 34 during workpiece machining.
  • the sheet 33 is displaced in the sheet metal plane with respect to the punching device 31 and the laser cutting device 32.
  • the sheet metal area to be processed in each case is displaced into the processing region of the punching device 31 or the laser cutting device 32.
  • sheet metal cutouts 36 are partially separated from a remaining work piece 37 by preliminary cutting, ie, the connection of the sheet metal cutouts 36 with the remaining work piece 37 is cut free, leaving a remaining joint 38.
  • the punching device 31 serves, alternatively or additionally, the laser cutting device 32.
  • Both the punching device 31 and the laser cutting device 32 can also be used for the final cutting.
  • the processing area of the punching device 31 is defined by the size of punching tools 39 inserted on it.
  • the processing region of the laser cutting device 32 is essentially determined by the maximum travel paths of a movement unit, not shown, of the laser cutting device 32.
  • the partially cut-away sheet metal cutouts 36 are positioned for final cutting by means of the coordinate guide 35 in such a way with respect to the punching device 31 or the laser cutting device 32 that their residual connection 38 is located in the processing region of the relevant cutting device.
  • a cutting cut is made by continuously moving the laser cutting beam along the cutting lines by means of the moving unit, not shown. Consequently, the sheet 33, similar to the punching cut by means of a sheared cutting punch, cut at different locations along the cutting lines offset in time.
  • connection 38 is positioned in such a way and the sheet cutouts 36 are cut free from the remainder of the work piece 37 by the preliminary cutting so that the sheet cutouts 36, when their remainder connection 38 lies in the working area of one of the cutters, are themselves largely arranged above an opening 41 in the work table 34 ,
  • the opening 41 can be opened and closed by means of a flap 42.
  • the flap 42 is open, after the final cutting cut, the completely cut-out sheet metal cutouts 36 fall under gravity from the remaining workpiece 37.
  • the sheet cutouts 36 are removed from the working area of the laser punch press 30 via a flap 42 and a chute 43. A particularly rapid removal of the sheet metal cutouts 36 takes place when the final cutting is performed with the flap 42 open.
  • the cut-sheet metal cutouts 36 can also be removed from the remaining workpiece 37 by handling devices, not shown, for example by means of a suction frame. Since the final cutting takes place on the stationary sheet, the cut-sheet metal cut-outs can be set before the final cutting on the handling device. For example, nipples of a nipple frame become just before the final one Cutting edges created on the cut-to-cut sheet metal cutouts. Thus, a process-safe removal of sheet metal cutouts is ensured. Frequently, cut-sheet metal cutouts are also removed manually. For safety reasons, the machine must be stopped completely with every single manual removal. By at least two sheet metal cutouts are cut and removed together, the downtime of the machine can be reduced.
  • the control program is created using a programming system.
  • a programming software on which the programming system is based causes later workpiece machining to take place in accordance with the above method.
  • the programming software automatically detects or influences the mutual arrangement of the sheet metal cutouts, the separating cuts in the preparatory and final cutting and the removal process of the sheet metal cutouts, so that sheet metal cutouts are cut and removed together.
