  • the punches are held in the punch holder so that they can be moved up and down, with the tops of the heads of the punches being smooth or flush with the upper surface of the punch holder.
  • Press heads are used with a head surface for pressing down the punch heads.
  • a depression-preventing stepped portion is movable by die head driving means such that either the head surface or the blunted portion is aligned with the respective punch head.
  • the die head driving means are controlled by a control circuit which generates binary-coded machining data corresponding to the punching pattern.
  • a device for punching workpieces with an upper tool and a lower tool wherein the upper tool is movable relative to the lower tool, wherein several punching dies and adjusting elements associated therewith are arranged in the upper tool, which can be moved between an actuating position in which the punching dies are moved when the Upper tool relative to the lower tool, and a non-actuated position in which the punches do not machine the workpiece when the upper tool moves relative to the lower tool, and wherein the upper tool has a first, upper punch guide plate with holes for the punches to pass through and a second punch guide plate facing the lower tool with holes for the punches to pass through. Furthermore, a second punch guide plate of the upper tool facing the lower tool is part of a hold-down element, wherein the friction of the punches within the holes of the hold-down element is higher than within the holes of the upper punch guide plates of the upper tool.
  • German utility model specification DE 20 2017103 498 U1 discloses a perforating machine with a machine table and a striking element that is movable relative thereto, with a perforating tool that is either mounted on the machine table or on the striking element and to which a die is assigned on the other part, for perforating a material web that is guided between the perforating tool and die in a drivable manner in its longitudinal direction.
  • means are provided for the simultaneous movement of the perforating tool and the die in the transverse direction to the material web.
  • German utility model specification DE 20 2014 104 997 U1 a punch with several punching dies, the punch heads of which are mounted in a punch receiving plate, is described.
  • the mounting of the punch heads in the punch receiving plate is designed in such a way that an undercut is created during the return stroke of the punching die, with a drive element indirectly moving the punch receiving plate.
  • the punch has at least one locking element which is assigned to at least one punching die and is located between the drive element and the punch receiving plate.
  • the locking element can be moved in two operating positions, with the locking element in a first operating position closing the gap between the drive element and the punch head of the at least one punch and in a second operating position the locking element forms a free space above the punch head of the at least one punch and wherein additionally the at least one punch is held by a braking element at least in the second operating position of the locking element.
  • each tool part is preferably assigned a locking element, the locking element having a locking and release position.
  • a contact surface is provided on the locking element, which is divided into surface areas, with recesses formed between the surface areas. This forms a toothing.
  • the required stroke of the locking element when it is transferred from the locking to the release position and vice versa can thus be limited to the tooth width.
  • the locking members and the adjustable tool parts are arranged in separable partial tools, for example cassettes. This makes it possible to stamp on different punches, i.e. different punch diameters, punch shapes, punch toothing, for example, without changing the unit with the bars and the drives. A high degree of variability and differentiation of the hole pattern produced by the hole punches is not possible.
  • the EP 0 508 557 A2 discloses a punching machine in which the individual punching dies can be activated or deactivated via movable locking elements. This makes it possible to produce a different punching pattern in an individual punching row. In order to produce a different punching pattern, complex conversion measures are required.
  • the JP H08323695 A discloses a punching device in which the individual punches are activated or deactivated via movable locking slides. can be deactivated. This device enables a punching pattern consisting of rows of punched holes and is not capable of creating delicate punched hole patterns. Furthermore, the assembly work required to change to a different hole punching pattern, for example with punched holes of different diameters, is very complex.
  • the punching tool and control block are screwed together using a large number of screw connections and are also attached to the machine frame.
  • the distance between the punching dies/perforating needles is relatively large due to the selected geometry, so that punching/perforation patterns with a small grid size cannot be produced.
  • the number of needles in the known punching/perforating machines is therefore very limited per unit area.
  • the present invention is based on the task or technical problem of specifying a punching/perforating machine that significantly reduces the times for maintenance or repair and thus enables economical use of such a punching/perforating machine.
  • the present invention is further based on the task or technical problem of specifying a punching/perforating machine which enables the creation of a variably predeterminable punching pattern, which ensures a significantly higher cycle rate of the perforation stroke compared to the known machines, enables an increased number of punching stamps/perforation needles per unit area compared to the known machines and ensures permanently reliable functionality.
  • extension profiles ensure that the associated punching/perforating needles are reliably activated when the punching/perforating stroke is carried out and the locking slide is activated.
  • the length of the extension profiles is individually designed to match the position of the associated punching/perforating needle.
  • a particularly preferred embodiment is characterized in that the punching tool and/or the control block are arranged so as to be retractable/extractable in the longitudinal direction in guide grooves provided within the punching machine.
  • a particularly advantageous development of the punching/perforating machine according to the invention is characterized in that the guide grooves are designed in such a way that additional adapter units can be introduced in order to enable the positive mounting of different geometries of punching tools or control blocks.
  • the inventive design with individual components relating to the punching tool and the control block that can be assembled independently of one another provides a system that is very flexible and, in the event of maintenance - for example, to grind the perforating needles or dies - or in the event of repairs, means that only individual components or parts thereof are replaced or removed in order to carry out the maintenance/repair measures.
  • the punching tool and the control block can be separated independently of one another, in contrast to the known systems in which the punching tool and the control block are completely screwed together in multiple connections and are also screwed to the machine frame.
  • the punching tool and control block can be changed quickly. This can reduce the changeover times for the two parts by up to 80% compared to the known systems. This means that the downtimes during regular maintenance and/or repair work can be significantly reduced compared to the known punching/perforating machines, which significantly increases the economic use of such punching/perforating machines.
  • a particularly preferred embodiment which enables the implementation of high cycle rates, is characterized in that the piston-cylinder unit is designed as a double-acting piston-cylinder unit with a first pressure chamber and a second pressure chamber, wherein the first pressure chamber is permanently subjected to a first pressure via the control device, which causes the locking slide to be in or held in the deactivation position, and when a punching or perforation is carried out, the control device subjects the second pressure chamber to a second pressure in the activation case, which is greater than the first pressure, so that the locking slide extends into the activation position and thereby, during the lifting movement, this movement is transferred to the associated punching punch/perforating needle, so that a punching or perforation of the material unit/web is carried out.
  • a particularly advantageous further development which ensures long-term functional use at high cycle rates, is characterized by the fact that the locking slide is connected in a form-fitting manner with axial and radial play to the corresponding piston rod of the piston-cylinder unit.
  • a particularly preferred embodiment which ensures a compact design of the control block in conjunction with a small grid dimension of the punching dies/perforating needles to be controlled, is characterized in that the control block has housings that can be individually controlled by the control device and that have a plurality of individually controllable piston-cylinder units arranged offset in the longitudinal direction and in the stroke direction.
  • a particularly advantageous embodiment of the punching/perforating machine according to the invention is characterized in that the piston-cylinder units arranged within the housing correspond in the longitudinal direction to an offset dimension of 0.5, 1 and 2 times or multiples of the grid dimension of the arrangement of the punching dies/perforating needles within the punching tool.
  • a particularly preferred design variant which enables efficient and economical use, is characterized in that a valve device is present which is controlled by the control device and is in communication with the piston-cylinder units of the control block.
  • a particularly preferred and advantageous embodiment of the punching/perforating machine according to the invention which significantly improves the handling of the machine for the operator and at the same time ensures a high level of functionality, is characterized in that a projection laser unit is provided which, depending on the data of the contour of the material to be processed or perforated stored in the storage device, images these contours on a feed table of the machine, thereby enabling exact alignment of the material and the position data recorded by the projection laser are then fed to the control device.
  • a particularly advantageous design which further increases functionality, is characterized in that the longitudinally displaceable extension profile has a step-shaped outer peripheral contour and the associated guide recess has a corresponding counter contour.
  • valve device which is remotely controlled by the control device, is designed as a unit that can be connected separately to the punching/perforating machine.
  • a particularly preferred structural design which has proven particularly effective in practice with regard to the required punching/perforation pattern to be produced, is characterized in that the housing has four cylinder-piston units and the control block/punching tool has four grid recesses arranged in the longitudinal direction in a grid-like manner and offset in the transverse direction for the extension profile or the punching die/perforating needles.
  • a particularly simple structural solution which is advantageous in terms of maintenance/repair and when changing the punching tool, is characterized by the fact that the spacer plate is attached to the top of the needle holder.
  • valve device can be designed as a pneumatic or hydraulic system.
  • the present invention therefore comprises an accessory unit, namely a punching unit for installation in a special design punching/perforating machine, whereby the machine can be equipped with various tool adapters to accommodate different tool profiles available on the market. This is possible by providing appropriate guide profiles for the control block and the punching tool.
  • any symmetrical and/or asymmetrical contours (shapes) can also be produced within specified dimensional and technical limits.
  • a piston-cylinder housing unit which is formed from four independently operating piston-cylinder units with piston rods. This results in a narrow structure.
  • control block and punching tool makes it possible to achieve the minimum distance between the punching dies/perforating needles in the tool, which corresponds to a standard perforation in automotive engineering, for example. This currently results in a maximum number of needles of 1024 needles on a perforation width of 1945.6 mm.
  • a mechanical extension (extension profile) is used.
  • This consists, for example, of a hardened round material with a stepped diameter, which rests loosely on the head of the needle.
  • the stepped outer diameter prevents the vertically installed extension profile in the control block from falling down when the tool is installed or removed.
  • this extension profile is held in a fixed position above the needle head by the aforementioned step.
  • the mechanical extension profiles are inserted in different lengths in the control block and assigned to the locking slides accordingly.
  • valve device which is integrated in four housing units within the machine and protected from damage or access. These housings contain the complete electronic and pneumatic control (valve islands, pressure control, pressure monitoring, etc.). These units are connected to the valves on the control block using a coupling system (multipole). Alternatively, the valve devices can also be flexibly mounted on appropriate transport frames in order to use them on various punching/perforating machines. This means that you are not dependent on just one work area.
  • the operation of the punching/perforating machine according to the invention is as follows: The geometric data of the perforation pattern are determined and recorded electronically. This data is transmitted to the storage device of the punching/perforating machine and evaluated by the control device.
  • the data of a given contour (external or internal shape) of the material to be perforated can be projected onto a lay-out table using a projection laser.
  • the material can be aligned using this image and this position data can be transmitted to the control device.
  • the control signals determined by the control device control the piston rods of the piston-cylinder units in the control block via the valve devices.
  • the constant counterpressure from the pressure accumulator unit (so-called air spring) acting on the piston-cylinder unit causes the piston rod to automatically return to its starting position, i.e. the deactivation position. This also retracts the locking slide and releases the limit at the upper end of the extension profile.
  • the punching punches or perforating needles and the extension profile above them are pushed back to the upper edge of the locking slide when they hit the material to be perforated. This means that no punching takes place. Since the guide of the punching punch/perforating needle and the associated extension profile are very smooth due to the system, the surface of the material to be perforated is not damaged.
  • the punching/perforating machine 10 shown schematically has a punching tool 12 and a control block 14.
  • the control block 14 is connected to a pressure bar 36, i.e. it is inserted and centered in a control block guide groove 42 provided on the pressure bar 36.

  • the lower part of the punching tool 12 with the dies is centered by means of a centering pin (not shown in detail). This lower part of the punching tool 12 is also placed in tool guide grooves 46.
  • the needle holder 34 forms together with the needle guide, which is firmly connected to the punching tool 12, a unit, namely the punching tool 12.
  • spacer plate 60 On the needle holder 34 there is a spacer plate 60, which on the one hand makes it easier to dismantle the punching tool 12 and on the other hand enables the use of other standard tools with the same tool profile but a different pitch.
  • the open spacer plate 60 which is provided with grid holes (see Figures 1 to 4 ), by a closed variant without grid holes (see Fig. 5 ) replaced.
  • the perforating needles 16 are arranged in a predetermined grid in the longitudinal direction L, which is perpendicular to the plane of representation of Fig. 1
  • the perforating needles 16 can be individually activated or deactivated for each perforation stroke H.
  • This individual control is implemented by providing a control device 30 which is in communication with a storage device 40 in which the geometric data of the perforation pattern to be created on a material web M fed to the punching tool 12 are stored.
  • the control device 30 is in communication with a valve device 26, wherein the valve device 26 has valve units, each of which is individually in communication with piston-cylinder units arranged on the control block 14.
  • the piston-cylinder units are designed as double-acting piston-cylinder units, with a cylinder 24, a piston 21 and a piston rod 20.
  • a first pressure chamber 28 and a second pressure chamber 32 In each piston-cylinder unit there is a first pressure chamber 28 and a second pressure chamber 32.
  • Each piston rod 20 is connected in its free end area to a locking slide 22, which can be moved from an activation position (extended state) and a deactivation position (retracted state) can be displaced in the sliding direction S transversely to the stroke direction H when the piston-cylinder unit is pressurized accordingly.
  • a first pressure accumulator 28.1 and a second pressure accumulator 32.1 are present, which communicate with the valve device 26.
  • the first pressure chamber 28 provides a pressure P1
  • the second pressure chamber 32 provides a pressure P2 that is greater than the pressure P1.
  • Each perforating needle 16 is assigned a locking slide 22 with an associated controllable piston-cylinder unit.
  • the locking slide 22 is spaced apart from the upper head end of the perforating needle 16.
  • an extension profile 48 is provided in the control block 14 in a corresponding guide, the underside of the extension profile 48 resting on the head of the associated perforating needle 16 and the upper front side of the extension profile 48 being arranged at the same height as the underside of the locking slide 22.
  • the locking slide 22 has in its free end area a contour 52 which runs inclined against the stroke direction H, which ensures that if the extension profile 48 or the perforating needle 16 has an upward projection, the extension profile 48 is pushed downwards and is not sheared off or damaged. This ensures permanently reliable functionality.
  • the first pressure chamber 28 and the second pressure chamber 32 are individually controlled via the valve device 26 and the control device 30, taking into account the stored perforation pattern data, as follows.
  • the first pressure chamber 28 is permanently pressurized with the pressure P1 via the first pressure accumulator 28.1, i.e. under the effect of the pressure P1, the locking slide 22 is in the retracted position, so that when the perforation stroke H is carried out, the associated perforating needle 16 does not carry out any perforation.
  • the control device 30 causes, via the valve device 26, that the second pressure chamber 32 is subjected to the pressure P2 via the second pressure accumulator 32.1, which is greater than the permanently present pressure P1 in the first pressure chamber 28, so that the locking slide 22 extends and, when the perforation stroke H is carried out, the associated perforating needle 16 in conjunction with the extension profile 48 carries out a perforation stroke H and creates a perforation on the material web M.
  • the control block 14 thus has piston-cylinder units that are individually controlled and subject to a permanent first pressure P1, which virtually forms an air spring in the return stroke, wherein for each perforating needle 16 to be controlled in the punching tool 12, a piston rod 20 is assigned to the corresponding piston-cylinder unit, which is activated, i.e. extended, by being subjected to the pressure P2.

These piston-cylinder units are arranged offset from one another in the stroke direction H and in the longitudinal direction L within the housing 38, with the housings 38 being present on both sides of the control block 14. This results in a narrow structure.
  • the connection to the locking slide 22 is made at the head of each piston rod 20 using a positive but loose connection. This connection allows play in both the axial and vertical directions. This counteracts possible damage to the extension profile 48 when the locking slide 22 is extended and retracted and improves functionality overall.
