  • This document discloses a machine tool in the form of a press for machining workpieces, wherein an upper tool is provided on a lifting device which can be moved relative to a workpiece to be machined along a lifting axis in the direction of the workpiece and in the opposite direction.
  • a lower tool is provided in the lifting axis and opposite the upper tool and is positioned towards a lower side.
  • a lifting drive device for a lifting movement of the upper tool is controlled by a wedge gear.
  • the lifting drive device with the upper tool arranged thereon can be moved along a positioning axis.
  • the lower tool is moved synchronously with the upper tool.
  • a machine tool in which, in the form of a press for machining workpieces, an upper tool is provided on a lifting device and can be moved along the lifting axis in the direction of the workpiece and a lower tool and in the opposite direction.
  • a table segment provided in the workpiece support for the workpiece to be machined can be lowered or pivoted downwards in order to eject the workpiece part separated from the workpiece.
  • the workpiece part falls downwards due to a tilting movement and slides along the table segment in the ejection direction.
  • the tool can then be picked up by a collecting container or the like.
  • a processing machine for processing plate-shaped workpieces is known. This has a transfer device in a working area by means of which the The workpiece part can be removed from the workpiece support after separation from the workpiece. Subsequently, subsequent processing is carried out using a subsequent processing tool on the workpiece part removed from the workpiece support. After subsequent processing, the workpiece part is then returned to the workpiece support located in the working area of the machine arrangement using this transfer device. Before the workpiece part stored on the workpiece support and the subsequent processing product stored on the workpiece support are removed from the working area of the processing machine together with the workpiece support using a removal device.
  • the invention is based on the object of proposing a method and a machine tool for machining workpieces, by means of which increased process reliability is enabled when removing at least one workpiece part separated from the workpiece.
  • a method for machining plate-shaped workpieces in particular sheet metal, in which an upper tool, which is movable along a lifting axis with a lifting drive device in the direction of a workpiece to be machined with the upper tool and in the opposite direction, is positioned with at least one motor drive arrangement along an upper positioning axis running perpendicular to the lifting axis, and in which a lower tool, which is aligned with the upper tool, is positioned with at least one motor drive arrangement along a lower positioning axis running perpendicular to the lifting axis of the upper tool.
  • the workpiece lies on a workpiece support for machining.
  • the upper and lower tools are moved in the interior of a machine frame, wherein the motor drive arrangements for moving the upper and lower tools are controlled by a controller.
  • at least one workpiece part is separated from the workpiece.
  • the upper tool is moved outside of a spatial volume that extends above the severed workpiece part and is formed by at least a predetermined part of the base area of the workpiece part in the workpiece plane and a perpendicular to the workpiece part in the direction of the upper positioning axis, or by a predetermined part of the base area and an area outside the base area of the workpiece part in the workpiece plane and a perpendicular to the workpiece part in the direction of the upper positioning axis.
  • the severed workpiece is removed.
  • This method for removing the at least one workpiece part severed from the workpiece has the advantage of increased process reliability. A moving movement of the workpiece part is not necessary to remove the severed workpiece part. After being separated or cut free, the workpiece part can remain in its position on the workpiece support until it is removed. In addition, an increased removal height is created within the machine frame of the machine tool above the workpiece part to be removed. This allows even larger workpieces to be removed reliably. This eliminates the risk of collision when removing the workpiece from the upper tool.
  • the at least one workpiece part is removed with a gripping device, which is moved above the workpiece and is positioned in the spatial volume before gripping.
  • a collision-free lifting movement of the gripping device can also be carried out to the extent It must be ensured that at least one workpiece part can be lifted relative to a workpiece or residual skeleton that may remain on the workpiece support in order to then, for example, guide the workpiece part out of the spatial volume in a plane above the workpiece and transfer it to an unloading position.
  • An alternative embodiment of the method provides that before a table segment provided in the workpiece support is lowered to discharge the at least one workpiece part separated from the workpiece, the upper tool is moved outside the spatial volume.
  • This has the advantage that a tilting movement of the workpiece part resting on it and to be discharged is possible when the table segment is lowered in the workpiece support, and the workpiece part can be discharged without collision.
  • a workpiece edge opposite in the discharge direction can perform a tilting movement.
  • the workpiece part can perform a free tilting movement when the table segment is lowered and is not hindered by the upper tool located above or the stripper of the upper tool. This also prevents damage to the upper side of the workpiece part during discharge.
  • the upper tool is moved along the upper positioning axis outside the spatial volume of the workpiece part before the lowering movement of the table segment is initiated.
  • a simple movement of the upper tool allows it to be quickly transferred to an area adjacent to the tilting area of the workpiece part, thus enabling short cycle times for collision-free removal.
  • the lower tool after a final separating cut or free cutting of a residual connection of the workpiece part to the workpiece and during the lowering of the
  • the table segment is positioned stationary in the last working position for ejecting the workpiece part. This also increases process reliability. After the workpiece part has been separated or cut free from the workpiece, the workpiece part, which is loose from the workpiece, remains in its position on the workpiece support until the table segment is lowered. This prevents the workpiece part from becoming caught or shifted above or below the workpiece.
  • the table segment is pivoted and lowered about a rotational axis aligned parallel to the upper positioning axis of the upper tool. This allows the table segment to be directly connected to the workpiece support surface, enabling safe removal after the table segment, which is also referred to as a pivoting parts flap, is lowered.
  • the spatial volume can be formed by a tilting area of a workpiece edge of the workpiece part that is opposite to the ejection direction when the workpiece part is ejected.
  • a length of the workpiece part to be ejected is released during ejection, the length of which includes the length of the lowerable table segment, and a distance between the workpiece support surface and an interfering edge of the machine frame arranged above it is determined.
  • the lateral movement of the upper tool increases the length of the workpiece parts to be ejected and expands the range of workpiece parts to be manufactured.

  • the workpiece to be machined lies on a workpiece support of the machine tool.
  • the workpiece machine has a control system by means of which the motor drive arrangements for moving the upper and lower tools can be controlled.

  • the movement space of the lagging workpiece edge forms the tilting area or the spatial volume.
  • the upper tool does not hinder such a tilting movement, since it is positioned outside the collision zone or tilt zone. This allows for collision-free ejection. Furthermore, damage to the upper side of the workpiece part being ejected, especially the good part, is avoided.
  • a preferred embodiment of the machine tool provides that the table segment is pivotably mounted along a rotational axis. This rotational axis is aligned parallel to the upper positioning axis.

  • the removal height between the workpiece plane and a bottom side of the upper horizontal frame leg 3 is reduced compared to if the upper tool 11 remains in the spatial volume 220, as is shown in the Figures 6 and 7 shown, increased.
  • This free space volume 220 enables a collision-free removal of the workpiece part 81 by discharging the workpiece part 81 downwards via a table segment 285, as described below in the Figures 8 to 12 or by removal by means of a gripping device 292, as described below with reference to Figures 13 and 14 described.
  • FIG 8 A simplified schematic representation of a workpiece 10 resting on the workpiece support 28, 29 is shown, which is being machined by an upper and lower tool 9, 11.
  • the workpiece 10 is moved in and against the X direction by the grippers 23 to create a cutting gap 83.
  • the upper and lower tools 9, 11 are moved accordingly in and against the Y direction along the upper and lower positioning axes 16, 25.
  • the workpiece support 28 comprises a table segment 285, which forms part of the workpiece support 28.
  • This table segment 285 can be lowered relative to the workpiece support surface 28 for discharging workpiece parts 81.
  • the table segment 285 is pivotally mounted about a rotation axis 286, which is aligned parallel to the positioning axis 16, 25.
  • the table segment 285 preferably extends over the entire width of the workpiece support 28, 29 in the Y direction.
  • the table segment 285 is flush with the adjacent workpiece support 8 due to the pivotable connection, so that after a lowering movement, the workpiece part 81 can be discharged downwards, as is the case, for example, in Figure 12
  • the discharge direction is shown by arrows 287.
  • the last cutting cut can be in the Y-axis.
  • the last cutting cut is in an X-axis, that is, starting from the beginning of a cutting gap 83 according to arrow 288 ( Figure 8 ) and a counterclockwise production of the cutting gap 83, for example, a workpiece edge 289 opposite the table segment 285 with respect to the rotation axis 286 is cut.
  • This workpiece edge 289 is oriented, for example, in the Y direction.
  • the upper tool 11 is moved along the upper positioning axis 16.
  • the lower tool 9 is held stationary relative to the lower positioning axis 25 in the last working position for separating or cutting free the workpiece part 81.
  • the upper tool 11 is moved by a distance relative to the lower tool 9 ( Figure 9 ), so that it is positioned outside the spatial volume 220. This has the advantage that during a tilting movement of the workpiece edge 289 about the rotation axis 286 after the lowering of the table segment 285, the workpiece part 81 does not collide with the upper tool 11.
  • a first phase of the discharge after lowering the table segment 285 is shown in perspective in Figure 10 and in a front view in Figure 11
  • the workpiece 10 resting on the table segment 85 which has a section with a final workpiece edge 289 that lies outside the support surface of the table segment 285, undergoes a tilting movement when the table segment 285 is lowered.
  • the workpiece edge 289 opposite in the discharge direction 287 is pivoted relative to a workpiece plane in the direction of the upper frame leg 3.
  • Such a maximum tilting movement of the workpiece part 81 is Figure 11 shown.
  • the upper tool 11 Due to the offset of the position axes 35 of the upper tool 11 relative to the position axis 48 of the lower tool 9, the upper tool 11 is positioned outside the collision area or the tilting area of the workpiece part 81. This allows the tilting movement to be carried out unhindered within the free space 220, and the workpiece part 81 can be discharged downwards.
  • a final phase of the discharge process is in Figure 12
  • the workpiece edge 289 has already been lowered and is below the workpiece plane of the workpiece 10.
  • the table segment 285 can be closed again in order to create a closed workpiece support 28. and the upper and lower tools 11, 9 are moved into position to the workpiece 10 for a new machining operation.
  • FIG 13 is an alternative embodiment of the machine tool to Figure 1 and 5
  • This machine tool 1 differs from the Figure 1 and Figure 5 that instead of or in addition to the laser processing device 201 according to Figure 5 a gripping device 292 is provided on the machine frame 2, which is controlled to be movable above the workpiece 10 via a linear drive 207, which is also arranged on the upper horizontal frame leg 3.
  • the laser processing device 201 can be provided on an opposite side wall on the horizontal frame leg 3 of the machine tool 1 and can have a similar structure as in Figure 5 have.
  • the linear drive 207 for the gripping device 292 can have a horizontal linear axis 293, along which a vertical linear axis 294 is movable along the Y-direction.
  • the gripping device 292 is arranged on the vertical linear axis 294 and comprises holding elements 295 facing the workpiece 10.
  • the holding elements 295 can be arranged and/or controlled individually or in groups. These holding elements 295 can be, for example, magnetic suction cups, vacuum suction cups, or electro-adhesion suction cups.
  • the individual groups of holding elements 295 can also be controlled individually in order to successively remove one or more workpiece parts 81 separated from the workpiece 10.
  • the gripping device 292 is positioned with at least one of the holding elements 295 in the spatial volume 220 above the workpiece part 81 to be removed in order to remove at least one workpiece part 81.
  • the upper tool 11 has been moved outside the spatial volume 220 before the holding elements 295 are positioned in the spatial volume 220, as can be seen from a schematically enlarged view according to Figure 14 In this perspective view according to Figure 14 the side of the machine frame 2 opposite the gripping device 292 is shown.
  • the upper tool 11 is positioned outside the spatial volume 220 of the severed workpiece part 81 by the upper drive assembly 17. This allows the holding elements 295 to be retracted and positioned unhindered into a position above the workpiece part 81 or the workpiece parts 81 in the spatial volume 220.
  • the lateral movement of the upper tool 11 before the removal of the at least one workpiece part 81 increases the removal height between the workpiece 10 and an underside of the upper horizontal frame leg 3.
  • the at least one workpiece part 81 can rest motionless on the workpiece support 28, 29 after separation.
  • the lower tool 9 remains stationary outside the spatial volume 220 during the movement of the upper tool 11 in the position in which the last separating cut for the workpiece part 81 took place.
  • the at least one holding element 295 is lowered.
  • the at least one workpiece part 81 is gripped, subsequently triggering a lifting movement of the holding elements 295 in the Z direction.
  • the workpiece part 81 is positioned above the workpiece plane of the workpiece 10.
  • the gripping device 292 with its holding elements 295 can be guided out of the spatial volume 220, and the workpiece parts can be transferred to an unloading position.
  • Such a gripping device 292 can increase automation.
  • the gripping device 292 and the linear drive 207 with the at least one linear axis 293, 294 are designed as an independent handling device.
  • This handling device can be assigned to one of the two workpiece supports 28, 29 and positioned adjacent to or adjacent thereto.
  • the gripping device 292 of such a handling device can be designed analogously to the Figure 13 and 14 described gripping device 292 for removing the workpiece parts 81 can be used and controlled.
