Definitions

  • the invention relates to a device for separating a number of workpieces from a strip of material, which has a separating unit to which the strip of material can be fed and in which the workpieces can be separated from the strip of material by acting on the strip of material, and the device has a transport device by which a workpiece strip containing the workpieces separated from the material strip and at least one residual strip containing the remaining area of the material strip can be moved further in a transport direction.
  • the invention further relates to a method for separating a number of workpieces from the strip of material, wherein the strip of material from one transport device of a device is fed to a separating station, a number of workpieces being separated from the material strip in this separating station, with a workpiece strip containing these workpieces and at least one residual strip containing the remaining area of the material strip processed in the separating station being moved out of the separating station.
  • the US-A 5,078,001 describes a device which has a punching machine, a strip transport device and a strip separating device as well as a first and a second winding device.
  • the stamping machine includes first and second sets of punches and dies, the first set between a first side of the strip of material and a centerline thereof and the second set between a second side of the strip of material and the aforementioned center line is arranged.
  • the first and second sets of punches and dies each include punches and dies for producing a first series of workpieces and a second series of workpieces from the strip of material. From this strip of material, which has side edges, blanks are produced by a cutting process. The blanks are then bent up or down in a U-shape.
  • this workpiece strip is split into two strips in a separating station, with the workpieces present on this first partial strip of workpieces being wound up on a roll and the workpieces present on this second partial strip of workpieces being wound up on a second roll.
  • the US-A 1,920,155 describes a machine for manufacturing cores for electrical apparatus and a method for their manufacture.
  • a material strip is formed which has a first partial strip with projections and a second partial strip with further projections which are separated from one another by slits in the material strip. These two workpiece partial strips are then separated from one another by cutting one strip out of the other strip.
  • a method that is particularly suitable for this purpose is also to be specified.
  • the separating station separates the material strip supplied to it into the workpiece strip containing the workpieces to be produced in one piece and the remaining strip or strips which contain the remainder of the material strip produced during the separating process of the workpieces in one piece, and that the separation station of the device in the transport direction of the strip of material below a separating station is arranged, through which the Workpiece strips containing workpieces are separated in a first plane and the remainder strip(s) containing the remainders of the strip of material produced during the separation process of the workpieces are separated in a second plane spaced apart from the first plane of the workpiece strip, so that the separating station contains a wedge-shaped separating element through which at least one remainder strip is at least is moved away laterally from the transport direction of the material strip, and that the narrow end of this wedge-shaped separating element faces the separating station.
  • the separating station contains a separating element which is wedge-shaped. By means of this separating element, at least one remaining strip can be moved away at least laterally from the transport direction of the material strip.
  • the separating element of the separating station of the device according to the invention thus facilitates the spatial separation of one or both residual strips from the workpiece strips containing the workpieces.
  • the method according to the invention provides that the device according to the invention is used to carry out the method, that in the separating station of the device a workpiece strip containing these workpieces and at least one residual strip containing the residues of the same resulting from the separating process of the workpieces from the material strip is produced in the separating station and from the separating station be moved out so that in a separating station of the device arranged downstream of the separating station in the transport direction of the material strip, the workpiece strip and the remaining strip or strips are spatially separated from one another in such a way that the workpiece strip is in a first plane and the remaining strip or strips of the material strip containing the remains of the material strip are in be transported to a further level spaced apart from the aforesaid first level.
  • the measures according to the invention advantageously ensure that the device according to the invention and the method according to the invention enable efficient production of dimensionally stable workpieces, including filigree workpieces, since the measures according to the invention eliminate the deformation forces acting on the workpiece during the cutting process or at least substantially reduced. It is advantageously possible to separate such workpieces from the strip of material in a single cutting operation, so that the production rate of such a device is increased considerably by the measures described.
  • the spatial separation of the remaining strips containing the remains of the strip of material enables them to be easily removed from the device according to the invention.
  • Another advantage here is that the residues of the strip of material produced during the cutting process are coherent, which simplifies the removal of the residue material, which also contributes to a higher cycle rate.
  • a further advantageous development of the invention provides that the separating station has at least two channels, with the workpiece strip being able to be guided in the first channel and at least one residual strip being able to be guided in at least one second channel, with a further advantageous development of the invention providing that at least one lower guide surface of the at least one second channel is arranged slightly inclined with respect to a working plane of the device. According to a further advantageous development of the invention, it is preferably provided that the at least one channel accommodating a residual strip runs inclined to the transport direction of the workpiece strip.
  • a device, generally designated 1, for separating workpieces W from a strip of material S is now shown schematically.
  • This consists essentially of a separating station 10, known per se and therefore not described in detail, which is used in a manner known per se to separate a workpiece W from the material strip S, and a separating station 20, in which - as also described below - the workpieces W are spatially separated from the remainder of the material strip S and the remainder of the material strip S is discharged together.
  • the figure 2 shows a plan view of the working plane of the device 1, the upper part of the separating station 10 shown in FIG. 1 has been omitted here for reasons of clarity.
  • the strip of material S is - in the representation of figure 2 - Supplied from the right of the device 1 in a manner known per se and therefore not described by a transport device (not shown). It then reaches the separating station 10 and the separating station 20.
  • a workpiece strip WS containing the workpieces W is fed out of the device 1 for further processing of these workpieces W.
  • the remainder of the material strip S here two remaining strips S', S" (see also figure 11 ), are discharged from the device 1 through discharge openings 20a, 20b.
  • the workpiece strip WS and the two remaining strips S' and S" of the originally flat strip of material S lie in different planes. It can be seen from the aforementioned figure that the workpiece strip WS lies below the remaining strips S' and S".
  • Such a procedure has the advantage that it enables precise and dimensionally accurate production of such workpieces W, in particular also of filigree workpieces W, in a simple manner, since, for the reasons explained below, deformations of the workpieces W during the cutting process, as they occur in encountered in known devices to date can be eliminated or at least substantially reduced. The reason for this is that any deformation forces arising during the cutting process are diverted into the two remaining strips S′, S′′ by the measures described and thus do not lead to a deformation of the workpieces W to be produced.
  • a further advantage of the procedure described is that it is now possible to detach even filigree workpieces W from the material strip S in a single cutting operation. With the device 1 described, it is thus advantageously no longer necessary for the production of such workpieces W to take place in two or more subsequent partial cutting processes. This advantageously leads to an increased production rate.
  • the cutting operation performed by the cutting station 10 is a shearing operation.
  • the measures described are not limited to such a shearing process. It can also be a punching or a cutting process for separation the workpieces W are used from a material strip S or another material-separating method which is based on the action of forces on the material strip S.
  • the changes that the person skilled in the art then has to make are obvious to him and therefore no longer need to be described.
  • a force-loaded stamp (not shown) of the separating station 10 preferably acts on the material strip S from above and cuts the material region of the same, which forms the workpiece W, into a cutting insert 25 lying below the material strip S (see Figures 3 and 4 ) presses, whereby the connection between the strip of material S and the area forming the workpiece W thereof is completely (punching, cutting) or partially (shearing) severed.
  • a force-loaded stamp (not shown) of the separating station 10 preferably acts on the material strip S from above and cuts the material region of the same, which forms the workpiece W, into a cutting insert 25 lying below the material strip S (see Figures 3 and 4 ) presses, whereby the connection between the strip of material S and the area forming the workpiece W thereof is completely (punching, cutting) or partially (shearing) severed.
  • the Figures 3 and 4 now show a section along the line AA of the figure 2 at the bottom dead center of the separation station 10, where - according to the representation of figure 2 - the upper part of the separation station 10 has been omitted.
  • the material region forming the workpiece W was separated from the material strip S by the punch of the separating station 10 being acted upon accordingly. This material area is thus in the cutting insert 25 of the cutting station 10 on an ejector 26.
  • the workpiece W and thus a workpiece strip WS containing the workpieces W lie below the edge region of the material strip S forming the remaining strips S', S".
  • the figures 5 and 6 now show the separation station 10 in its top dead center.
  • the workpiece strip WS containing the workpieces W lies in a first plane and the two remaining strips S', S" lie in a second plane above the aforementioned first plane.
  • Such a separating process is known and therefore does not need to be described further.
  • the strip of material S is advanced further.
  • the workpiece strip WS is guided in a first channel 22a running in the base body 20' of the separating station 20.
  • the first remaining strip S' is guided in a channel 22b and the second remaining strip S" is guided in a channel 22c of the separating station 20.
  • the channel 22a runs essentially in a straight line in the transport direction, while the channels 22b and 22c are at an angle to the Transport direction and thus run to the channel 22a.
  • the figures 7 and 8th now show a section along the line BB of the figure 2 .
  • the workpiece W cut out of the strip of material S as described above is thus already in the separating station 20 following the cutting station 10.
  • This has--as in particular from FIG figure 1 can be seen - a separating element 21, which is wedge-shaped in the exemplary embodiment shown here, the narrow end of this wedge-shaped separating element 21 facing the separating station 10.
  • the separating element 21 has the task of deflecting the remaining strips S′, S′′, which until now have run parallel to one another, outwards so that the remaining strips S′ and S′′—as best figure 1 can be seen - can be discharged from the device 1 through corresponding discharge openings 20a, 20b.
  • the separating station 20 has channels 22a, 22b and 22c for the different sub-strips WS, S' and S" of the material strip S fed out of the separating station 10, which - in a drawing plane of figure 2 and thus viewed in the Z direction orthogonal to the working plane 2 of the device 1 - run at different heights.
  • a central channel 22a which runs in a lower first plane, serves to guide the workpiece strip WS containing the workpieces W.
  • Further channels 22b, 22c are arranged on both sides of this, which serve to guide the first remaining strip S' and the second remaining strip S''. These two channels 22b, 22c are arranged in a second level lying above the first level.
  • the lower guide surface 23b of the channel 22b is not parallel to the lower guide surface 23a of the workpiece strip WS receiving channel 22a, but runs outwards sloping slightly inclined in relation to the working plane 2.
  • the lower guide surface 23c of the channel 22c also arranged sloping outwards.
  • the channels 22b and 22c accommodating the remaining strips S' and S" do not run parallel to the channel 22a accommodating the workpiece strip WS, but are arranged to run obliquely outwards to this channel 22a allows the spatial separation of the workpiece strip WS from the remaining strips S' and S" in a direction that is inclined to the transport direction.
  • both channels 22b and 22c it is not necessary for both channels 22b and 22c to be inclined at the same time; for certain purposes it can be quite sufficient if only one of these two channels 22b, 22c away from channel 22a.
  • the figures 9 and 10 now show a section along line CC of figure 2 . It can be seen that the lower guide surface 23c of the channel 22c now again runs approximately parallel to the lower guide surface 23a of the channel 22a. Since the two residual strips S', S" - as described above - have already been sufficiently separated by the separating element 21 of the device 1, and above all the residual strip S" guided in the channel 22c is already sufficiently far away from the workpiece strip WS, a further tilting of the residual strip S" is no longer necessary. As can also be seen from the figure, the wider residual strip S', which is guided in the channel 22b, is still partially above the workpiece strip WS, so that further lifting of this residual strip S' is expedient .
  • the configuration of the channels 22a-22c described here is only of an exemplary nature. Depending on the intended use of the device 1, it can be changed within wide limits.
  • the design of the channels 22a-22c depends in particular on the width of the respective strips WS, S' and S". It should be selected in such a way that, on the one hand, the workpiece strips WS can be transported away from the device 1 unhindered by the remaining strips S', S". and that, on the other hand, the residual strips S', S" can be easily removed from the device 1.
  • any configuration is possible , in which it is achieved that the strip running in the corresponding channel 22a-22c is channeled in a certain direction, i.e. guided in this direction.
  • the term “channel” is thus to be understood in its broadest meaning and functionally oriented and therefore not limited to the "trench-like" configuration shown in the exemplary embodiment described in terms of geometry and construction.
  • the device 1 preferably has a processing station 30, in particular a punching or cutting station, arranged in front of the separating station 10, which serves to introduce the aforementioned openings D into one or preferably into both edge regions of the material strip S by removing the corresponding material regions from the Strips of material S are cut out.
  • a processing station 30 in particular a punching or cutting station, arranged in front of the separating station 10, which serves to introduce the aforementioned openings D into one or preferably into both edge regions of the material strip S by removing the corresponding material regions from the Strips of material S are cut out.
  • an already prepared, i. H. provided with the aforementioned expansion openings material strips S to use.
  • the figure 12 now shows a further embodiment of such a strip of material.
  • the difference between the material strips S the figures 11 and 12 is that the strip of material S of figure 11 is now formed in two parts, ie it has only the workpiece strip WS and only one remaining strip S'. From the above description it is clear to the person skilled in the art how to modify the device 1 described above. In particular, only two guides 22a, 22b are then required and the separating element 21 can preferably also be omitted.
  • the measures described advantageously enable more efficient production of workpieces from a strip, strip or plate-shaped base body such as the material strip S, which was used as an example to explain the functioning of the device 1 described.
  • the Workpiece strips WS containing workpieces W and the residual strip or strips S', S" containing the remaining area of the starting material strip S are spatially separated from the separating station 10 of the device 1, which causes the workpieces W to be separated out of the material strip S, in at least two different planes, viz in a first level, in which the workpiece strip WS is transported further, and in at least a second level, in which or in which the remaining strip or strips S', S" are transported further, it is achieved in an advantageous manner that by acting on the Deformation forces caused by the material strip S are dissipated in the remaining strip or strips S', S", so that the risk of deformation of the workpiece or workpieces W is eliminated or at least significantly reduced.
  • This advantageously also makes it possible to easily produce delicate work
  • a further advantage of the measures described is that the workpieces W can now be cut out of the material strip S in a single cutting operation, as a result of which the production speed of such a device 1 is significantly increased.
