Definitions
- the invention relates to a method for obtaining at least two workpiece cutouts from a plate-like workpiece, in particular of at least two sheet metal cutouts from a sheet, wherein by preparative cutting cutting while moving the workpiece, the connection between the workpiece cutouts and the remainder workpiece by means of a cutting device partially, ie, leaving a Remaining compound is cut, wherein after the preliminary Trennschnei- the final cutting of the workpiece cutouts with the remaining workpiece by means of a cutting device along at least one cutting line is cut by final cutting and the workpiece cutouts are removed after the final cutting of the remaining workpiece.
- a method for obtaining sheet metal cutouts from a sheet is described in DE-C-38 32 215.
- 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 nibbling device. Due to the separating cuts the connection between several sheet metal cutouts and a remaining workpiece is partially severed.
- 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 creates a final separating cut on the stationary sheet which extends over the entire width or length of the sheet. Several along the cutting line of the final one
- the aim of the invention is to provide a method which is extended in terms of its capabilities over the previously known method.
- this object is achieved by the method according to patent 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.
- This is how it is invented In accordance with this, it is also possible to machine workpieces which are larger than the processing area of the cutting device for the final cutting.
- 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 remaining connection between the workpiece cut-outs and the remainder workpiece is simultaneously cut free by the final cutting along the entire cutting 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 cutting according to the invention by the flexibly applicable and process-safe separation process of punching and / or laser cutting takes place.
- 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 remainder workpiece is cut free by the preparatory cutting so 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 connection according to the invention between the workpiece cutouts and the remaining 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.
- Figures Ia to Id a first sheet at different times in the course of a process for obtaining two
- Figure 2 a second sheet with partially cut away
- FIG. 3 is a perspective view of a laser
- Punching press for obtaining sheet metal cutouts from a sheet metal.
- a machine tool is used, as shown in FIG. 3 and as described in detail below.
- Figure Ia 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 remainder of the workpiece 3 in the direction of cursing each other, d. H. rectilinearly extending cutting lines 7 is larger than the processing area 5 of the cutting device according to FIG. 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. Based on the conditions according to FIG. 1a, the remaining connection 4 between the sheet metal cutouts 2 and the remaining work piece 3 is shortened in the direction of the cutting lines 7. For this purpose, while moving the sheet 1 relative to the cutting device, the sheet metal areas to be processed are brought into the processing area 5 of the cutting device. By means of the cutting device, the separating cuts 6 are lengthened in the direction of the cutting lines 7. Upon completion of the preparatory separation, the conditions set in FIG. 1b are established.
- FIG. 1c shows sheet metal 1 with sheet-metal cutouts 2 cut free entirely from frame-type remaining workpiece 3. Starting from the situation according to FIG. 1c, the cut-away sheet metal cutouts 2 are simultaneously removed from the frame-like residual workpiece 3. In Id, the remaining 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 cutouts 2, the production time per sheet 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.
- FIG. 2 shows further possibilities for releasing sheet metal cutouts from a sheet metal 10. All the sheet metal cutouts shown are in the state immediately before the final cutting cut. They are therefore still partially connected to the remainder of work 11. In the case of the sheet metal 10, the remaining work piece 11 of sheet metal cutouts assigned to one another comprises not only unprocessed sheet metal areas, but also each other, partially cutaway sheet metal cutouts.
- 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. Cutting 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.
- the cut-together metal sheet cut-outs each have an identical shape. In principle, however, it is also possible to cut out blank sections of different shapes together.
- FIG. 3 shows the machine tool designed as a laser stamping press 30, on which the above method for obtaining sheet metal cutouts from a metal sheet is carried out.
- 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-out sheet metal cutouts 36 are positioned for final cutting by means of the coordinate guide 35 with respect to the punching device 31 or the laser cutting device 32 in such a way that their residual connection 38 lies in the processing region of the relevant cutting device.
- the residual compound 38 is positioned in such a way and the sheet metal cutouts 36 are cut free from the remainder of the workpiece 37 by the preparatory cutting, that the sheet metal cutouts 36, if their
- Residual compound 38 is located in the processing area of one of the cutting devices, even largely over an opening 41 in the workpiece table 34 are arranged.
- 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 out of the remaining workpiece 37 under the action of gravity.
- 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-free 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, suckers of a suction frame are placed immediately before the closing separating cutters created on the cut sheet metal cutouts. Thus, a process-safe removal of sheet metal cutouts is ensured.
- cut-outs are also removed manually.
- 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.
